BACRGROUND OF THE INVENTION
It is well known in the construction industry that significant econo~uc 20 savings can be realized by reduc;ng the ~mollnt of work required at the construction site. To achieve this objective, pref~ri~tio~ has been adopted on alarge scale in the construciion industry, both with respect to general purpose b~ din~s and with respect to personal houcinP. For ~mI-le, some sources have estim~ted that as many as forty pcrcent (40%) of the homes now being built use 25 some form of pre-m~nllf~ lred stTuctural co~ Moreover, four and seven-tentbs percent (4.7~o) of all housing starts in the U.S. in 1991 are bomesthat are completely modular, and this percen~age is expected to rise. The ultimate goal to be achieved in building modular structures has been to produce,at a remote site and in a factory environment, as many of the components of a 30 given structure as possible, leaving only site prepalation and final assembly to be done at the actual location where the building is to be sitll~te~l SUBSTIT~JTE SHEET
wo 93/10315 PCT/CA92/00492 Therc are a number of advantages to be achieved by prefabrication.
The most obvious of those advantagcs is the cienific~nt reduction of time and labor required at the job site, wherc labor costs are normally thc highest. In addition to the reduced time required for actual erection of the building, otherS time savings are also possible. For e~a.llple, the reduced amount of work time at the job site reduces the potential for interruptions resulting from inclement weather. Reduced time at a job site can also drastically reduce the potential for work-related injuries and/or deaths. A controlled factory at nosphere is inherently ~men~le to measures for re~ucir~e injuries and increasing safety.
Furt_ermore, increased uni~o,~ of the structural components resn1ting from the enh~nced quality control possiblc in a &ctory atmosphere and the economic advantages of mass production techniques are also achievable vith t_e prefabrication approach. As is often the s;t~ ;ol-, the use of standardi ed,prefabricated structural components not only ill-pro.es the nniformity of the end lS product but also greatly simpLfies thc actual erection process. This last feature also makes it possible to produce quality buil~tingc vith unsldlled, or minim~lly sldlled, personnel. Thus, the overall rcsults of prefabrication in the construction industry include greatly ~I~.o~ed effi~ency, signLficantly reduced costs, lower accident rates and better safety records These advantages are, of cour~e desirable in any type of construction, but are believed to be especially illl~ll~t in the production of individual dwellings, particularly in economically ~ essed areas and in third world countries where cost is one of the most si~nifi~nt obst~rles to overcome.

FIG. S is a p~ c represent~tion of one form of an anchor block employed in the roof-to-wall cQI~neetion of the present invention; and, FIG. 6 is a vertical section through an e~e...plary roof-peak connection embodying the concep~s of the present invention.
DESCRIPIlON OF AN EXEMPL~RY EMBODIMENT
One represent~ e form of a roof-to-wall cont~c~lor means embodying the concepts of tbe present invention is desi~ted generally by the numeral 10 on the acco~pan~ing ~ swiUgS. Thc rcpresent~hvc roof-to-wall connc.lor means 10 may, for e~mpk be employed in a ~ni1-1ing structure which could se~ve as 2S res;denh~1 living quarters.
With particu~ar referencc to FIGS. 1 and 2, the ~l.lposile structure which cons~ tcs thc p,...~pal c~..,poncnt of the walls, and even the roof, of the modular structure for which the present c~nncctor means assembly is particularlysuited is the panel member 11. That portion of tbe wall 12 represe-nted in nG. 230 is formed by two, long;tudin~lly aligned panel members 11A and 11B which are joined by 8 panel connc~;lor 13.
As previewed in the previous paragraph, and as will appear in the detailed desc.;ption which follows, a parti~ular stmctural member, component or SUBSTITUTE SHEE~
WO 93/10315 ~ ~ ~ 3 7 13 - 6 - PCT/CA92/00492 arrangement may be employed at morc than onc location. When referring generally to that type of structural membcr, component or arrangement a common nurnerical designq-tion shall bc cmploycd. However, when one of the stn-ct lral members, components or arr~ng~mentC so idcnhficd is to bc S individually identifie.d it shall bc rcfcrcnced by ~irtuc of a lcttcr sufflx cmployed in com~a~on with the numerical de,;~y.al;on cmploycd for general identification of that structural member! component or al.; ngc-. e-~l Thus, there are at least two panel members whuch arc generally ide-ntified by the numeral 11, but the spectfir individual panels are, thercforc, identified as 11A and 11B in the spec~cation and on the drawings. This samc suffix con~nlion.shall be cmployed throughout thc spe~fication.
Returning to the description of the arr-qng~me-nt dcpictcd in FIG. 2, thc wall pancl members 11 each have a body portion 14. The body portion 14 has planar, transverscly space~t~ subst~nti-qlly parallcl, skin walls 15 and 16. A
plurality of rcinforcing ribs, not shown, prcfcrably cxtend trans~erscly betweenthe skin walls 15 and 16. Thc ribs arc, thcmceh~cs, latcrally spacc~l, one wit_ respect to thc othcrs, and they arc oricntcd subst~ntiqlly parallel to the lateral edges of thc body portion 14 - i~, pcrpendicu~arly with rcspcct to thc skin walls 15 and 16.
Thc lon~itudin~l cdgcs of the body portion 14 arc de-tineated by poCitioning cho~llders 18 and 19 prcscntcd at thc oppositc ends of each skin wall.
As dcpicted in FIG. 2, a positioning shouldcr 18A dcfinw ODC longitudinal edgc of skin wall 15 on pancl llA, and a co.lw~onding, and latcrally spaccd, pos;lioning sholl1der l9A dcfines onc lon~tudin-ql edgc of skin wall 16 of pancl11A. T_c positionirlg shol~lders 18A and l9A thus dcfinc one lor~tll~t;n~l cdgc of thc body portion 14 on pancl llA as wcll as t_e offsct junchlre betwcen the body portion 14 and thc conne~ing tongue 20A which c~t~o-n~ls lon~ 1in~11y outwardly from that vertical edge of the body portion 14 on panel 11A defined bythe positioning shoulders 18A and 19A.
Similarly, a positioning shoulder 18B defines the oppositc longitudinal edge of skin wall 15 on panel 11B, and a corresponding, and laterally opposed, positioning shoulder 19B defines the opposite lon~tu~in~l cdge of wall sldn 16 on panel 11B. The positioning shoulders 18B and 19B are laterally spaced ~om SUBSTITI.)TE SHEET
wo 93/1031~ PCT/CA92/00492 -7 212371~
each other, and longitu~lin~lly opposed to the positioning shoulders 18A and 19Aon panel 11A. As in pancl 11A, the positioning sho1llders 18B and l9B define one longitudinal edge of the body portion 14 on panel 11B as well as the offset lre between the body portion 14 and the CQ~ C.I;~ tongue 20B which S erte-nds longit~--lin~lly outwardly from that longitudinal edge of the body portion 14 on panel 11B define~ by the positioning sholllders 18B and 19B.
The conncc~ ton~es 20 each have a transversely oriented closure wall 21 that is spaced longitudinally outwardly from the lon~itu~in~l edge of the body portion 14 defined by the positioning shoulders 18 and 19. The transverse edges of thc closure wall 21 are joined to transversely spaceA longitudinally exte-n-lin~, locking waLls ~ and 23. A vertically ertenAin~ locking groove 25 isrecessed into each connecting tongue 20 between each locking wall 22 and 23 and the body portion 14 such that locking grooves 25A~ and 25A2 lie parallel to shoulders 18A and 19A, respcctively, of panel 1L~ Similarly, locking grooves 25Bl and 25B2 lie parallel to shoulders 18B and 19B of panel 11B.
lhe pair of tongues 20A and 20B presented from the lon~itu(lin~l edges of the linearly aligned panels 11A and 11B, rcsl~ccti~ely, have a transverse thickncss that is less that the transverse thicl~ness of the. body portion 14 in either panel membcr 11.
Specifically, thc locking walls 22 are laterally of~set with respect to the lonE~itu-lin~lly and Yertically oriented plane within which the exposed surface 26 on skin wall 15 is disposed, and the locking walLs 23 arc laterally offset with respect to thc IQ~itU~1;n~11Y and vertically oriented plane within which the cxposed surfacc ~8 on skin wall 16 is disposed. It is thcse lateral offsets of the locking walls ~ and 23 relative to thc respectivc surfaces 26 and 28 on the two skin walls 15 and 16 which results in the transverse, or laterally measured, thickness of the tonglles 20 being less that the L~ c,sc, or laterally measured,thic~rness of the body portion 14 on cither panel member lLA or 11B. The ~lnction~l purpose for this deliberate disparity bet veen the transverse thickness of the tongues 20 relative to the trans-~erse thi~ l~ness of the body portion 14 in each panel member 11 will be hereinafter more fully explained.

Typically, a panel connccLor 13 has a body portion 30 that is preferably of box-shaped cross ~ctiolt That is, tbe body portion 30 is hollow and has a generally rectiline~r~ external periphery w~ich defines a plurality of exterior faces such as the four 31, 32, 33 and 34 depicted. Tbe box-5 shaped cross section provides excellent bending strength with minim~l material aswell as ~Y~e~ nt eQhlmn~ strength with a superb L/R ratio.
Conneeti~ flanges 3S are presented from the body portion 30 in oppositely ~yten(~ pairs. Eaeh flange 35 has an extenciQn ann 36 with endc tbat are pro~.~.al and distal with respect to the body portion 30 from which each 10 extension arm 36 is presente~l The proxibllal end portion of each extencion arm 36 is integral with the body portion 30 in such a l..a~cr that each eYtencion arm is oriented in perpendicular relation with respect to one adjacent face but also in longitudinal ~li~m~nt ~ coplanar - with anothcr face on the body portion 30.
As can be ;een with reference to FIG. 2, the extension ann 36A is oriented not only in perpendicular relation with respect to the exterior face 31but also in coplanar relation with respect to exterior face 34. LikewLce, the eYtencion arm 36B is oriented not only in pc~c~ r relation with respect to the exterior face 31 but aLco in coplanar relation with respect to the exterior face 3~ The eyten~;on ar ns 36A and 36B are thus dispoced in transversely spaced, parallel relation to form the first col-nccl;on receptacle 40~

As sucb, the PYten~on arm 36C is oriented not only in perpendicular relation with respect to the exterior face 33 but also in coplanarrelation with respect to tbe exterior face 34.

A locking pawl 41C also extends- L.~e,sely outward~y from the distal end porffon of e~ler~sion arm 36C, and a locking pawl 41D e~tenrl~ transversely outwardly from the distal end of e~ten~;on arm 36D. The locking pawls 41C and 10 41D thus also extend toward each other in facing opposition within the connecting receptacle 40B.
The heretofore defined wall panel members 11 and the panel connectQrs 13 permit the wall 12 to be either directly assembled in their final,vertical dis~os;tion, or assembled at ground level and then raised into tbeir final, 15 vertical position. Either approach is acceptable, but there will likely be those who prefer one method over the other.
To erect a wall 12 ut sinl at least one laborer will require a ladder, stilts or some form of scaffolding. In this situadon two sequential panel members 1lA and l1B may be positioned in linear juxtaposidon, and the laborer on the 20 scaffolding, or the like, may take a coupling cQ~nc~lor 13 and slide it vertically betveen the linearly juxtaposed panel members 11A and llB such that, as depicted in FIG. 2, the connc~ receptacle 40A on the panel conncclor 13 operadvely engages the connecting tongue 20A on panel 11A and the cQnn~cting receptacle 40B on the panel co~ncc~or 13 operatively engages the connecting 25 tongue 20B on panel member llB.
Operative engagement of the connecting receptacles 40 on the panel Co~eclor 13 with the tongues 20 on tbe panel members 11 requires that the locking pawls 41 in the co~nc~l;on receptacles 40 mesh with the locking grooves 25 associated vith each the cormecting tong~ue 20. In fact, the locl~ng pawls 4130 are slidably received within the locl~Dg grooves 25. So engaged, the panel member 11A and llB are fully tied to the panel connector 13, and thus to each other.

As~noted previously, composite panel m~mherc 11 may alco constitute 5 the principal component of the roo~ To preclude confilcion tbe panel memberc shall, wben used ac a eo~poneDt of tbe roof itseLf, be de-sign~ed by the numerical ide-ntifier 45. The roof panel memberc 45 are, as depicted in FIG. 1, connt~cted to, and SuppOI led by, the waJl 12, the struciural arrangement for which has now been descr;ibed. The roof panel member 45 also has opposed skin walls 46 and 48, sldn wall 46 presentin~ tbe exterior surface 49 of the roof panel 45,and skin wall 48 presenhng that surface 50 which faces interiorly of tbe structure covered by the roof panel members 4S.
With additional reference to FIG. 1 it will be observed tbat an aperture S1 penetrates tbe sl~n wall 48 preser~ g the interior surface S0 on theroof panel member 45. The aperture S1 is of suffir~nt rtimenciQn to be read;ly received over the locking bead S2 of an anchor dowel SS, as will be hereinafter described in greater detail.
As can be seen fFom FIG. 1, an end cap 60 serves to determine the pitch at wbich the roof panel member 45 is inrlincd with respect to the vertically disposed wall 12. Each end cap 60 h~ a ho.~ontal base 61, and a vertically oriented, short riser 62 is conjoined to the base 61 at apl,ro. ;.n~tely tbe outer extent of the base 61. A vertically oriented, long riser 63 is similarly conjoined at tbe inner extent of tbe base 61. Tbe difference in the vertical extent of the risers 62 and 63 determines the pitch at which the roof panel member 45 is inctinert, as should now be apparent. An inrl;ned plate portion 65 is di~osed in spaced relation upwardly of the base 61 and may be integral with the risers 62 and 63.
The base 61 and the inrtined plate portion 65 are each provided w;th res~ccti~e apertures 66 and 68. The apertures 66 and 68 are aligned and are alsoof sufficient tlimerlcion to permit the locking head 52 of the anchor dowel 55 to be received therethrough. Reinforcing walls 69 and 70 extend substantially vertically between the base 61 and the inclined plate portion 65, and they are preferably disposed in parallel relation to the risers 62 and 63. Although only two re~for~,ng walls 69 and 70 are depicted in the drawings, it should be SUBSTITlJTE SHE~T
wO 93/1031~ PCT/CA92/00492 understood that the space which extends vertically between the apertures 66 and 68 may be s~lounded by re~forcing walls in order to provide additional strength to the end cap 60, if required, or desired.
A pair of mou~t~g fJanges 71 and 72 extend downwardly from tbe S base 61, and they are preferably disposcd in ~ ...cn~ with the risers 62 and 63, respectively, and are laterally spaced contiguously to engage the surfaces 34 and 32 on the body portion 30 of the panel cQnnector 13 as well as the exposed surfaces 26 and 28 (F~G. 2) on the skin walls 15 and 16 of each panel member 11. As such, the end cap 60 embracingly engages the wall panels 11A and 11B, 10 as they are conjoined by the panel connectQr 13, as well as the panel conneaor 13 itseL~
At the juncture of each mo~lntln~ flangc 71 and 72 with the base 61 is an en~ging step 73. When the end cap 60 is received on the panel member(s) 11 forming the wall 12,.the steps 73 cngage thc upwardly directcd edges 74 and 75 of the walls 34 and 32 on the conn~ctQr 13 as well as the upwardly directed edges 76 and 78 (FIG. 4) of the coplanar walls 15 and 16 on the wall panel membcrs 11. Thc steps 73 thus servc to cffcct accuratc pl~cemcnt of the cnd cap 60 with respect to the wall 12 OD which it is recc.~cd.
A plurality of recesses 79 arc formed in the base 61. The recesses 79 20 may, as reprcsentcd, be disposed in proxi~ to the eng~ging steps 73. The recesses 79 serve to align, and position, the anchor dowel 55, as will be herein~ler more dully explained.
The utilization of one component for multiple purposes also enh~nces the concept of modularity. An excellent eY~ of this multiple utilization is 25 that the end cap 60 can not only bc cmployed along the upper extent of the panel membcrs 11 f~,~il,g the wall 12 ~ut also along the outer edge of the roof panel members 45 which form the roof 45, where the plate portion 65 becomes the fascia 6SA. The apertures 66 and 68 which ~ccQmmodate the locking head 52 of the anchor dowel 55 then se~e as ventDation openings to the interior cavity 80 3Q of t_e roof panel 45. In that situation at least the outer aperture 68 may beprovided with a screen 81, or other means, by which to preclude the a~lmicsion of bugs, birds or rodentc. To provide a means by which to drain any undesired liquid from ~cQlmnl~ting within the cavity 80, apertures 82 and 83 may penetrate SUBSTITUTE SHEET

the long riser 63 and the reinforcL~g wall 70, respectively, and an apert~re 84 may penetrate the base 61 and open through the recess 79 adjacent the long rLer 70.
The anchor dowel 55 is a generally cylindAcal structure, having a 5 cylin~ body portion 85 the upper extent of which termin~es in a locking head 52 which hac at least one L~ e (limenC-on that is greater than a correspond~g ha~~ e ~ ens:cn of the of body portion 85. As best seen in FIG. 5, the body portion 85 as weD as the locking head 52 may both be cylindAcal.
T~e anchor dowel 55 has two positioning arrays, a vertically upper array 86, and a lower array 88, which assure that the body portion 85 is locatedcentrally within the cavity 89 within tbe con--e. lor 13. The upper array 86 mayemploy four individual arms 90 whicb extend radially outwardly from the body portion 85, each of which terminate in an en~eing tab 91. The arrns 90 are 15 preferably spaced at angular increments of 90 degrees about the circumference of tbe body portion 85, and each e~ ng tab 91 is angularly disposed with respect to the a~as of the arm 90 &om which it is present~d so as to engage one of the recesses 79 (I;IGS. 1-3) formed in thc eDd cap 60. The eng~n~ tabs 91 also iDterfit between the base 61 (witbin recess 79) of the eDd cap 60 and the closure 20 waLI 21 of tbe ap~rop.iate toDgue 2Q
The lower array 88 may aLso employ four individual arms 92 which extend radially outwardly from the body portion 85, each of which terminate in an eng~n~ wedge 93. The arms 92 are also preferably spaced at angular increments of 90 degree about tbe circumference of the body portion 85. The 25 e~gin~ wedges 93 eacb rece;~ed within tbe in~hlde~ angle fonned by tbe intersection of tbe sides 31, 32, 33 and 34 forrnin~ the body portion 30 of the panel conncctor 13. Tbe lower array 88 is preferably located at the very bottom of body portion 85. The vertical dist~nce between the upper and lower arrays 86 and 88 may be se]ected to assure that the lower array 88 may be buried to a 30- sufflcient extent within the cementitious material introduced into the cavity 89 within the connector 13 to provide the desired resistance against lifting of theroof stn~cture off the supporting wall 12 and also to permit a dose fit between the end cap 60 and the components of the upper array 86. When those SUBSTITUTE SHEET
Wo 93/10315 PCT/CA92/00492 21~3713 14-conditions are met, the vertical distance between the upper array 86 and the locking head 52 will ~cco-~ odate an anchor block 95 (F~GS. 1 and 5) which is interposed between the locking head 52 and the base 61 of end cap 60 to tie the roof panel 45 to the wall 12, as will be herein~ftcr descn~ed in greater detaiI.The surface on that lengtb of tbe anchor ~owel body portion 85 which extends between the locking head 52 and tbe plate portion 65 of the end cap 60 is preferably provided witb vertical striations 96 coope~aLi~,ely to interact with an anchor block 95, as will be bereinafter more fully descn~ed.
The anchor block 95 is geDcrally wedge shaped, with a trapezoidal, vertical cross-secdon as best seen in FIG. 1. Three sides of this trapezoidal cross-section -~e: sides 98, 99 and I00 - are perpendicular to each other, but the rem~ining side 101 is inclined at angle equal to the pitch ~ of the roof panel 45. The anchor block 95 has a central slot 102 which opens through side 100.
The lateral sides 103A and 103B of the slot 102 has vertical striations 104 which are locl.ingl~ engageable with the striadons 96 on the body portion 85 of the anchor dowel 55.
As shouId now be readily understood, when the anchor dowel 55 is secured within the conne.~or 13 the locking head 52 and a length of the body portion 85 w~l extend upwardly through the aperture 51 in the plate portion 65 so that an aperture SI in the skin wall 48 of the roof panel 45 can be received over the locking head 52. When the interior surface 50 on the skin wall 48 thlLccontiguously engages the plate portion 65 an anchor block 95 will be i~ctalled into the cavity 80 of the roof panel 45 (the end cap 60 not yet having been positioned on the roof panel 45). A workman need only position the slot 102 in ~ e~t with that length of the body portion 85 which e~te-n~lc into the cavity 80 of the roof panel 45 and then drive the anchor block 95 wedgingly between the locking head 52 and the plate portion 65. The in~eraction of the striations 96 on he body portion 85 of the anchor dowel 55 and the striations 104 on the anchor block 95 m~int~inC the wedging action of the anchor block 95 and thereby secures the roof panel 45 to the wall 12. The end cap 60 may then be applied to the roof panel 45. As shown in FIG. 1, the end cap 60 may be applied by fitting the moun~ g flanges 71 and 72 embracingly to engage the skin walls 46 and 48 SUBSTITUTE SH~ET

on the roof panel 45. The end cap 60 may be ret~ined by an adhesive or other fastening means.
A roof-peak connector means adapted to join the roof panels 45 is desi~ted generally at 110 in nG. 6. The roof-peak cQnnectQr means 110 may employ a ridge beam 112. The ridge bearn 112, like the wall panel members 10, also has a body portion 114 with transversely sp~ceA, s~bst~nt~lly parallel, skin walls 115 and 116, with at least the upper edge of each skin wall 115 and 116 terTnin~-in~ in positioning shoulders 118 and 119, respectively. A tongue 120 extends vertically upwardly from the positioning shoulders 118 and 119, which define the of~set juncture between the body portion 114 of the ridge beam 112 and the tongue 120.
The tongue 120 also has a transversely oriented closure wall 121 that is spaced vertically upward]y from thc longin~-lin~lly extending positioning shoulders 118 and 119. The transverse edges of the closure wall 121 are joined to transversely spaced, vertically disposcd, and lon~itudin~lly eYterl-iing~ locking walls l~ and 123. Lon~-tuAin~lly c~en(ling lochng grooves 125 are recessed i~to the connectin~ tongue 120 between each locking wall l~ and 123 nd the reactive shou]ders 118 and 119.
The tongue 120 may also have a trarLcverse thickness that is less than the transverse thickness of the body portion 114. This offset may be ~ccomplished in the same manner as the offset is ~ccomrlished in the wall panel members 11 previously descn~ed.
A ridge cap 130 is provided which cooperatively engages the tongue 120 on the ridge beam 112. The ridge cap 130 h~s a pair of laterally spaced brace members 126 that may, ac shown have trapezoidal cross sectiQnC. The central portions of one parallel sidc 128, . preferably the longest, on each trapezoid are conjoined by a horizontal web in the nature of a base 129. The base, or web, 129 overlies the closurc wall 121 of the tongue 120, and a longihl-lin~lly eYten~ling locking pawl 130 projects outwardly from the one parallel side 128 of each brace member 126 to be received within each locldng groove 125. The parallel sides 128A and 128B thus serve to embrace the tong~e 120 of the ridge beam 112.

In the representative S embodiment depicted the exposed sidc wall 133 is inclined at the same angle ~
as the plate wall 131. As shown, the plate wall 131 may be provided with an extension 131A which projects past the one parallel side 128 of each brace member 126.
Spring clips 135 may be used to secure; the roof panels 45 to the extension 131A on each brace member 126, and a ridge vent 140, as is well known to the ar~ may be used to cover the gap between the roof panels 45 at the apex of the roo~ The ridge vent 140 does not form a part of the present invention.
As should now be apparent, the present invention not only teaches 15 that a roof anchor embodying the concepts of the present invention provides a means by which to securc a roof to a wall with mass produced structural components that can be utilized by unchlled labor without special tools. By employing the concepts of the present inveDtion the roof can be erected and secured in place and in a far shorter time than the same job could be 20 accomplished by traditional components and sl~lled labor. It should now also be apparent that the other objects of the present invention are likewise accomplished.

DESCRIPIlON OF AN EXEMPL~RY EMBODIMENT
One represent~ e form of a roof-to-wall cont~c~lor means embodying the concepts of tbe present invention is desi~ted generally by the numeral 10 on the acco~pan~ing ~ swiUgS. Thc rcpresent~hvc roof-to-wall connc.lor means 10 may, for e~mpk be employed in a ~ni1-1ing structure which could se~ve as 2S res;denh~1 living quarters.
With particu~ar referencc to FIGS. 1 and 2, the ~l.lposile structure which cons~ tcs thc p,...~pal c~..,poncnt of the walls, and even the roof, of the modular structure for which the present c~nncctor means assembly is particularlysuited is the panel member 11. That portion of tbe wall 12 represe-nted in nG. 230 is formed by two, long;tudin~lly aligned panel members 11A and 11B which are joined by 8 panel connc~;lor 13.
As previewed in the previous paragraph, and as will appear in the detailed desc.;ption which follows, a parti~ular stmctural member, component or SUBSTITUTE SHEE~
WO 93/10315 ~ ~ ~ 3 7 13 - 6 - PCT/CA92/00492 arrangement may be employed at morc than onc location. When referring generally to that type of structural membcr, component or arrangement a common nurnerical designq-tion shall bc cmploycd. However, when one of the stn-ct lral members, components or arr~ng~mentC so idcnhficd is to bc S individually identifie.d it shall bc rcfcrcnced by ~irtuc of a lcttcr sufflx cmployed in com~a~on with the numerical de,;~y.al;on cmploycd for general identification of that structural member! component or al.; ngc-. e-~l Thus, there are at least two panel members whuch arc generally ide-ntified by the numeral 11, but the spectfir individual panels are, thercforc, identified as 11A and 11B in the spec~cation and on the drawings. This samc suffix con~nlion.shall be cmployed throughout thc spe~fication.
Returning to the description of the arr-qng~me-nt dcpictcd in FIG. 2, thc wall pancl members 11 each have a body portion 14. The body portion 14 has planar, transverscly space~t~ subst~nti-qlly parallcl, skin walls 15 and 16. A
plurality of rcinforcing ribs, not shown, prcfcrably cxtend trans~erscly betweenthe skin walls 15 and 16. Thc ribs arc, thcmceh~cs, latcrally spacc~l, one wit_ respect to thc othcrs, and they arc oricntcd subst~ntiqlly parallel to the lateral edges of thc body portion 14 - i~, pcrpendicu~arly with rcspcct to thc skin walls 15 and 16.
Thc lon~itudin~l cdgcs of the body portion 14 arc de-tineated by poCitioning cho~llders 18 and 19 prcscntcd at thc oppositc ends of each skin wall.
As dcpicted in FIG. 2, a positioning shouldcr 18A dcfinw ODC longitudinal edgc of skin wall 15 on pancl llA, and a co.lw~onding, and latcrally spaccd, pos;lioning sholl1der l9A dcfines onc lon~tudin-ql edgc of skin wall 16 of pancl11A. T_c positionirlg shol~lders 18A and l9A thus dcfinc one lor~tll~t;n~l cdgc of thc body portion 14 on pancl llA as wcll as t_e offsct junchlre betwcen the body portion 14 and thc conne~ing tongue 20A which c~t~o-n~ls lon~ 1in~11y outwardly from that vertical edge of the body portion 14 on panel 11A defined bythe positioning shoulders 18A and 19A.
Similarly, a positioning shoulder 18B defines the oppositc longitudinal edge of skin wall 15 on panel 11B, and a corresponding, and laterally opposed, positioning shoulder 19B defines the opposite lon~tu~in~l cdge of wall sldn 16 on panel 11B. The positioning shoulders 18B and 19B are laterally spaced ~om SUBSTITI.)TE SHEET

each other, and longitu~lin~lly opposed to the positioning shoulders 18A and 19Aon panel 11A. As in pancl 11A, the positioning sho1llders 18B and l9B define one longitudinal edge of the body portion 14 on panel 11B as well as the offset lre between the body portion 14 and the CQ~ C.I;~ tongue 20B which S erte-nds longit~--lin~lly outwardly from that longitudinal edge of the body portion 14 on panel 11B define~ by the positioning sholllders 18B and 19B.
The conncc~ ton~es 20 each have a transversely oriented closure wall 21 that is spaced longitudinally outwardly from the lon~itu~in~l edge of the body portion 14 defined by the positioning shoulders 18 and 19. The transverse edges of thc closure wall 21 are joined to transversely spaceA longitudinally exte-n-lin~, locking waLls ~ and 23. A vertically ertenAin~ locking groove 25 isrecessed into each connecting tongue 20 between each locking wall 22 and 23 and the body portion 14 such that locking grooves 25A~ and 25A2 lie parallel to shoulders 18A and 19A, respcctively, of panel 1L~ Similarly, locking grooves 25Bl and 25B2 lie parallel to shoulders 18B and 19B of panel 11B.
lhe pair of tongues 20A and 20B presented from the lon~itu(lin~l edges of the linearly aligned panels 11A and 11B, rcsl~ccti~ely, have a transverse thickncss that is less that the transverse thicl~ness of the. body portion 14 in either panel membcr 11.
Specifically, thc locking walls 22 are laterally of~set with respect to the lonE~itu-lin~lly and Yertically oriented plane within which the exposed surface 26 on skin wall 15 is disposed, and the locking walLs 23 arc laterally offset with respect to thc IQ~itU~1;n~11Y and vertically oriented plane within which the cxposed surfacc ~8 on skin wall 16 is disposed. It is thcse lateral offsets of the locking walls ~ and 23 relative to thc respectivc surfaces 26 and 28 on the two skin walls 15 and 16 which results in the transverse, or laterally measured, thickness of the tonglles 20 being less that the L~ c,sc, or laterally measured,thic~rness of the body portion 14 on cither panel member lLA or 11B. The ~lnction~l purpose for this deliberate disparity bet veen the transverse thickness of the tongues 20 relative to the trans-~erse thi~ l~ness of the body portion 14 in each panel member 11 will be hereinafter more fully explained.
With contimled reference to FIG. 2, the panel connector 13 is employed to effect a structural tie between the tvo, linearly oriented panel SUBSTITUTE SHEET
WO 93/1031~ PCT/CA92/00492 2~ 3~13 members 11A and 11B. Typically, a panel connccLor 13 has a body portion 30 that is preferably of box-shaped cross ~ctiolt That is, tbe body portion 30 is hollow and has a generally rectiline~r~ external periphery w~ich defines a plurality of exterior faces such as the four 31, 32, 33 and 34 depicted. Tbe box-5 shaped cross section provides excellent bending strength with minim~l material aswell as ~Y~e~ nt eQhlmn~ strength with a superb L/R ratio.
Conneeti~ flanges 3S are presented from the body portion 30 in oppositely ~yten(~ pairs. Eaeh flange 35 has an extenciQn ann 36 with endc tbat are pro~.~.al and distal with respect to the body portion 30 from which each 10 extension arm 36 is presente~l The proxibllal end portion of each extencion arm 36 is integral with the body portion 30 in such a l..a~cr that each eYtencion arm is oriented in perpendicular relation with respect to one adjacent face but also in longitudinal ~li~m~nt ~ coplanar - with anothcr face on the body portion 30.
As can be ;een with reference to FIG. 2, the extension ann 36A is oriented not only in perpendicular relation with respect to the exterior face 31but also in coplanar relation with respect to exterior face 34. LikewLce, the eYtencion arm 36B is oriented not only in pc~c~ r relation with respect to the exterior face 31 but aLco in coplanar relation with respect to the exterior face 3~ The eyten~;on ar ns 36A and 36B are thus dispoced in transversely spaced, parallel relation to form the first col-nccl;on receptacle 40~
A locking pawl 41 eYten~ .,.scly oulw~dly from the distal end portion of each extension arm 36. Spe~fi~lly, locldng pawl 4L~ is presented from the dist~l eDd portion of t~e eYt~nc;on arrn 36A, and pawl 41B is presentedfrom the distal end portion of the extension arm 36B. The pawls 41A and 41B
so provided extend toward each other in facing opposilion in the first connc.lion receptacle 40A~
The panel co~c~lor 13 also presents a second pair of eYten~ion arms 36C and 36D wbicb extend out vardly from the body portion 29 in a diametrically 3~ opposite direction relative to the first pair of extension arms 36A and 36B, respe~.,ely. As sucb, the PYten~on arm 36C is oriented not only in perpendicular relation with respect to the exterior face 33 but also in coplanarrelation with respect to tbe exterior face 34. Likewise, the extension arm 36D is SUBSTITU~E SHEE~

A locking pawl 41C also extends- L.~e,sely outward~y from the distal end porffon of e~ler~sion arm 36C, and a locking pawl 41D e~tenrl~ transversely outwardly from the distal end of e~ten~;on arm 36D. The locking pawls 41C and 10 41D thus also extend toward each other in facing opposition within the connecting receptacle 40B.
The heretofore defined wall panel members 11 and the panel connectQrs 13 permit the wall 12 to be either directly assembled in their final,vertical dis~os;tion, or assembled at ground level and then raised into tbeir final, 15 vertical position. Either approach is acceptable, but there will likely be those who prefer one method over the other.
To erect a wall 12 ut sinl at least one laborer will require a ladder, stilts or some form of scaffolding. In this situadon two sequential panel members 1lA and l1B may be positioned in linear juxtaposidon, and the laborer on the 20 scaffolding, or the like, may take a coupling cQ~nc~lor 13 and slide it vertically betveen the linearly juxtaposed panel members 11A and llB such that, as depicted in FIG. 2, the connc~ receptacle 40A on the panel conncclor 13 operadvely engages the connecting tongue 20A on panel 11A and the cQnn~cting receptacle 40B on the panel co~ncc~or 13 operatively engages the connecting 25 tongue 20B on panel member llB.
Operative engagement of the connecting receptacles 40 on the panel Co~eclor 13 with the tongues 20 on tbe panel members 11 requires that the locking pawls 41 in the co~nc~l;on receptacles 40 mesh with the locking grooves 25 associated vith each the cormecting tong~ue 20. In fact, the locl~ng pawls 4130 are slidably received within the locl~Dg grooves 25. So engaged, the panel member 11A and llB are fully tied to the panel connector 13, and thus to each other.

A good disclosure of these products and the process for their preparation can be found in U.S. Pat. ~o. 4,536,360, the subject matter of which30 is incorporated herein by reference.
As should be evident to those sk;lled in thc art, practice of the present invention does not require that the structural col~ponents comprise nnyl chloride resins reinforced by glass fi~er and therefore, the invention is not to be limited SUBST~TUTE SHEET

The roof panel memberc 45 are, as depicted in FIG. 1, connt~cted to, and SuppOI led by, the waJl 12, the struciural arrangement for which has now been descr;ibed. The roof panel member 45 also has opposed skin walls 46 and 48, sldn wall 46 presentin~ tbe exterior surface 49 of the roof panel 45,and skin wall 48 presenhng that surface 50 which faces interiorly of tbe structure covered by the roof panel members 4S.
With additional reference to FIG. 1 it will be observed tbat an aperture S1 penetrates tbe sl~n wall 48 preser~ g the interior surface S0 on theroof panel member 45. The aperture S1 is of suffir~nt rtimenciQn to be read;ly received over the locking bead S2 of an anchor dowel SS, as will be hereinafter described in greater detail.
As can be seen fFom FIG. 1, an end cap 60 serves to determine the pitch at wbich the roof panel member 45 is inrlincd with respect to the vertically disposed wall 12. Each end cap 60 h~ a ho.~ontal base 61, and a vertically oriented, short riser 62 is conjoined to the base 61 at apl,ro. ;.n~tely tbe outer extent of the base 61. A vertically oriented, long riser 63 is similarly conjoined at tbe inner extent of tbe base 61. Tbe difference in the vertical extent of the risers 62 and 63 determines the pitch at which the roof panel member 45 is inctinert, as should now be apparent. An inrl;ned plate portion 65 is di~osed in spaced relation upwardly of the base 61 and may be integral with the risers 62 and 63.
The base 61 and the inrtined plate portion 65 are each provided w;th res~ccti~e apertures 66 and 68. The apertures 66 and 68 are aligned and are alsoof sufficient tlimerlcion to permit the locking head 52 of the anchor dowel 55 to be received therethrough. Reinforcing walls 69 and 70 extend substantially vertically between the base 61 and the inclined plate portion 65, and they are preferably disposed in parallel relation to the risers 62 and 63. Although only two re~for~,ng walls 69 and 70 are depicted in the drawings, it should be SUBSTITlJTE SHE~T
wO 93/1031~ PCT/CA92/00492 understood that the space which extends vertically between the apertures 66 and 68 may be s~lounded by re~forcing walls in order to provide additional strength to the end cap 60, if required, or desired.
A pair of mou~t~g fJanges 71 and 72 extend downwardly from tbe S base 61, and they are preferably disposcd in ~ ...cn~ with the risers 62 and 63, respectively, and are laterally spaced contiguously to engage the surfaces 34 and 32 on the body portion 30 of the panel cQnnector 13 as well as the exposed surfaces 26 and 28 (F~G. 2) on the skin walls 15 and 16 of each panel member 11. As such, the end cap 60 embracingly engages the wall panels 11A and 11B, 10 as they are conjoined by the panel connectQr 13, as well as the panel conneaor 13 itseL~
At the juncture of each mo~lntln~ flangc 71 and 72 with the base 61 is an en~ging step 73. When the end cap 60 is received on the panel member(s) 11 forming the wall 12,.the steps 73 cngage thc upwardly directcd edges 74 and 75 of the walls 34 and 32 on the conn~ctQr 13 as well as the upwardly directed edges 76 and 78 (FIG. 4) of the coplanar walls 15 and 16 on the wall panel membcrs 11. Thc steps 73 thus servc to cffcct accuratc pl~cemcnt of the cnd cap 60 with respect to the wall 12 OD which it is recc.~cd.
A plurality of recesses 79 arc formed in the base 61. The recesses 79 20 may, as reprcsentcd, be disposed in proxi~ to the eng~ging steps 73. The recesses 79 serve to align, and position, the anchor dowel 55, as will be herein~ler more dully explained.
The utilization of one component for multiple purposes also enh~nces the concept of modularity. An excellent eY~ of this multiple utilization is 25 that the end cap 60 can not only bc cmployed along the upper extent of the panel membcrs 11 f~,~il,g the wall 12 ~ut also along the outer edge of the roof panel members 45 which form the roof 45, where the plate portion 65 becomes the fascia 6SA. The apertures 66 and 68 which ~ccQmmodate the locking head 52 of the anchor dowel 55 then se~e as ventDation openings to the interior cavity 80 3Q of t_e roof panel 45. In that situation at least the outer aperture 68 may beprovided with a screen 81, or other means, by which to preclude the a~lmicsion of bugs, birds or rodentc. To provide a means by which to drain any undesired liquid from ~cQlmnl~ting within the cavity 80, apertures 82 and 83 may penetrate SUBSTITUTE SHEET

the long riser 63 and the reinforcL~g wall 70, respectively, and an apert~re 84 may penetrate the base 61 and open through the recess 79 adjacent the long rLer 70.
The anchor dowel 55 is a generally cylindAcal structure, having a 5 cylin~ body portion 85 the upper extent of which termin~es in a locking head 52 which hac at least one L~ e (limenC-on that is greater than a correspond~g ha~~ e ~ ens:cn of the of body portion 85. As best seen in FIG. 5, the body portion 85 as weD as the locking head 52 may both be cylindAcal.
T~e anchor dowel 55 has two positioning arrays, a vertically upper array 86, and a lower array 88, which assure that the body portion 85 is locatedcentrally within the cavity 89 within tbe con--e. lor 13. The upper array 86 mayemploy four individual arms 90 whicb extend radially outwardly from the body portion 85, each of which terminate in an en~eing tab 91. The arrns 90 are 15 preferably spaced at angular increments of 90 degrees about the circumference of tbe body portion 85, and each e~ ng tab 91 is angularly disposed with respect to the a~as of the arm 90 &om which it is present~d so as to engage one of the recesses 79 (I;IGS. 1-3) formed in thc eDd cap 60. The eng~n~ tabs 91 also iDterfit between the base 61 (witbin recess 79) of the eDd cap 60 and the closure 20 waLI 21 of tbe ap~rop.iate toDgue 2Q
The lower array 88 may aLso employ four individual arms 92 which extend radially outwardly from the body portion 85, each of which terminate in an eng~n~ wedge 93. The arms 92 are also preferably spaced at angular increments of 90 degree about tbe circumference of the body portion 85. The 25 e~gin~ wedges 93 eacb rece;~ed within tbe in~hlde~ angle fonned by tbe intersection of tbe sides 31, 32, 33 and 34 forrnin~ the body portion 30 of the panel conncctor 13. Tbe lower array 88 is preferably located at the very bottom of body portion 85. The vertical dist~nce between the upper and lower arrays 86 and 88 may be se]ected to assure that the lower array 88 may be buried to a 30- sufflcient extent within the cementitious material introduced into the cavity 89 within the connector 13 to provide the desired resistance against lifting of theroof stn~cture off the supporting wall 12 and also to permit a dose fit between the end cap 60 and the components of the upper array 86. When those SUBSTITUTE SHEET
Wo 93/10315 PCT/CA92/00492 21~3713 14-conditions are met, the vertical distance between the upper array 86 and the locking head 52 will ~cco-~ odate an anchor block 95 (F~GS. 1 and 5) which is interposed between the locking head 52 and the base 61 of end cap 60 to tie the roof panel 45 to the wall 12, as will be herein~ftcr descn~ed in greater detaiI.The surface on that lengtb of tbe anchor ~owel body portion 85 which extends between the locking head 52 and tbe plate portion 65 of the end cap 60 is preferably provided witb vertical striations 96 coope~aLi~,ely to interact with an anchor block 95, as will be bereinafter more fully descn~ed.
The anchor block 95 is geDcrally wedge shaped, with a trapezoidal, vertical cross-secdon as best seen in FIG. 1. Three sides of this trapezoidal cross-section -~e: sides 98, 99 and I00 - are perpendicular to each other, but the rem~ining side 101 is inclined at angle equal to the pitch ~ of the roof panel 45. The anchor block 95 has a central slot 102 which opens through side 100.
The lateral sides 103A and 103B of the slot 102 has vertical striations 104 which are locl.ingl~ engageable with the striadons 96 on the body portion 85 of the anchor dowel 55.
As shouId now be readily understood, when the anchor dowel 55 is secured within the conne.~or 13 the locking head 52 and a length of the body portion 85 w~l extend upwardly through the aperture 51 in the plate portion 65 so that an aperture SI in the skin wall 48 of the roof panel 45 can be received over the locking head 52. When the interior surface 50 on the skin wall 48 thlLccontiguously engages the plate portion 65 an anchor block 95 will be i~ctalled into the cavity 80 of the roof panel 45 (the end cap 60 not yet having been positioned on the roof panel 45). A workman need only position the slot 102 in ~ e~t with that length of the body portion 85 which e~te-n~lc into the cavity 80 of the roof panel 45 and then drive the anchor block 95 wedgingly between the locking head 52 and the plate portion 65. The in~eraction of the striations 96 on he body portion 85 of the anchor dowel 55 and the striations 104 on the anchor block 95 m~int~inC the wedging action of the anchor block 95 and thereby secures the roof panel 45 to the wall 12. The end cap 60 may then be applied to the roof panel 45. As shown in FIG. 1, the end cap 60 may be applied by fitting the moun~ g flanges 71 and 72 embracingly to engage the skin walls 46 and 48 SUBSTITUTE SH~ET

on the roof panel 45. The end cap 60 may be ret~ined by an adhesive or other fastening means.
A roof-peak connector means adapted to join the roof panels 45 is desi~ted generally at 110 in nG. 6. The roof-peak cQnnectQr means 110 may employ a ridge beam 112. The ridge bearn 112, like the wall panel members 10, also has a body portion 114 with transversely sp~ceA, s~bst~nt~lly parallel, skin walls 115 and 116, with at least the upper edge of each skin wall 115 and 116 terTnin~-in~ in positioning shoulders 118 and 119, respectively. A tongue 120 extends vertically upwardly from the positioning shoulders 118 and 119, which define the of~set juncture between the body portion 114 of the ridge beam 112 and the tongue 120.
The tongue 120 also has a transversely oriented closure wall 121 that is spaced vertically upward]y from thc longin~-lin~lly extending positioning shoulders 118 and 119. The transverse edges of the closure wall 121 are joined to transversely spaced, vertically disposcd, and lon~itudin~lly eYterl-iing~ locking walls l~ and 123. Lon~-tuAin~lly c~en(ling lochng grooves 125 are recessed i~to the connectin~ tongue 120 between each locking wall l~ and 123 nd the reactive shou]ders 118 and 119.
The tongue 120 may also have a trarLcverse thickness that is less than the transverse thickness of the body portion 114. This offset may be ~ccomplished in the same manner as the offset is ~ccomrlished in the wall panel members 11 previously descn~ed.
A ridge cap 130 is provided which cooperatively engages the tongue 120 on the ridge beam 112. The ridge cap 130 h~s a pair of laterally spaced brace members 126 that may, ac shown have trapezoidal cross sectiQnC. The central portions of one parallel sidc 128, . preferably the longest, on each trapezoid are conjoined by a horizontal web in the nature of a base 129. The base, or web, 129 overlies the closurc wall 121 of the tongue 120, and a longihl-lin~lly eYten~ling locking pawl 130 projects outwardly from the one parallel side 128 of each brace member 126 to be received within each locldng groove 125. The parallel sides 128A and 128B thus serve to embrace the tong~e 120 of the ridge beam 112.
SUBSTITU~E SHE~T
WO 93/10315 PCr/CA92/00492 The upper, or plate, wall 131 prese-nted from the brace member 12~ is inclined at the pitch angle a of the roof panel 45, but the other parallel wall 132 as well as the exposed sidc wall 133, respectively, may be disposed in whatever is deemed by the user to be aesthetically pleasing. In the representative S embodiment depicted the exposed sidc wall 133 is inclined at the same angle ~
as the plate wall 131. As shown, the plate wall 131 may be provided with an extension 131A which projects past the one parallel side 128 of each brace member 126.
Spring clips 135 may be used to secure; the roof panels 45 to the extension 131A on each brace member 126, and a ridge vent 140, as is well known to the ar~ may be used to cover the gap between the roof panels 45 at the apex of the roo~ The ridge vent 140 does not form a part of the present invention.
As should now be apparent, the present invention not only teaches 15 that a roof anchor embodying the concepts of the present invention provides a means by which to securc a roof to a wall with mass produced structural components that can be utilized by unchlled labor without special tools. By employing the concepts of the present inveDtion the roof can be erected and secured in place and in a far shorter time than the same job could be 20 accomplished by traditional components and sl~lled labor. It should now also be apparent that the other objects of the present invention are likewise accomplished.
