' 2,249,106 v BUILDING ooNs'ra'Uo'rioN i Leroy aumgaru, chicago, ni. Application-July 11, 1940, serial No. 3443857. "15 claims. (o1. 10s-13)v My invention relates to building-construction, and has particular reference 'to a roof construction of the flat deck type, although the sameconstruction may be used for Walls or sides of buildings, if desired.

The primary object of the invention `is the` provision 'of a' building structure'of substantially pre-fabricated form which can be installed in unit construction to provide a `roof or wall construction protecting the building against various elements such as wind, rain, V'snow Vand the like, and serving the purpose 'of' the usual enclosure for a building.

Another and further object of my invention is the provision of a building structure which is so constructed that it may expand when becoming heated, as when exposed to the sunsrayS,

or contract dueto cold weather, and yet remain weatherand water-proof under all normal weather conditions Another and further 'object is the -provision ofi a building structure which is exible within limitsV and which will yield toa lcertain extent to the action of the wind or the up-'currents of air underneath a roof or to down-current's'dueto unusual disturbed atmospheric conditions, andV yet will retain the necessary strength 'to perform Vits functions 'without weakening 'to any material degree.

Aiurther object of my invention', particularly i when used as a roof structure, 'is that it is suinciehtlystrong to withstand 'ordinary 'weight such as that of an individual walking upon it, and which in normal use will give long years` of service, particularly if thevupper surface is kept -panhaving material. such as 'fibreboelrd mastic material or fibrous insulating mate-rial in plastic form', or the like, permanently secured or afnxed to the under side thereof so the under side of Vthe Ametal pans is protected from condensation,

rust and the like,A vand an insulating or sounddeadening effect is secured, these units being prepared so they can easily and quickly be fitted into position duringthe construction of a roof. TheseV and other'objects of imy invention will be more ence to Which- Figure embodying my invention, showing the unit in the successive stages of installation;

'Figure 2 is 'a cross-sectional -view on line 2--2 ofFigure 1; l Figure 3 is a longitudinal viewpart-ially in section and partially in elevation Yofvfone of the capi members;

the accompanying drawings,V and `in Figure 4 is a perspective View of one of the corner cap members used in the structure; Y

Figure 5 is a channel-shaped star member used for anchoring the support and transverse `members together Vat the corners;

-1-1 of Figure 1.

Referring 'now specically to the drawings,

land in which like reference Vcharactersreier to likerparts throughout, the usualpurlin VI!! is shown, a plurality -of which are used inspaced parallel relation.' Witheach other, upon which is placed parallel extending'spaced support members designated asV ay whole asl-I, `I-| ,"these members extending;transversely voi `the purlin lil. These support members Il, H are "in the preferred vforrn composed of a channel section t2 having'ilanges 13,13 extending from each side thereof, with angular 'disposed webs i4, 'lilv connecting the flanges and-"the body of the channel fsecti'on I2.

provided having its base 4portions angularly dis- A U-shaped channel section `I5 'is posed to lit in parallel relation against the webs M, 14' of the ychannel section I2, andvis 'spotwelded or otherwise secured to the 'channel sec- `tio'n 12 so that in'ef'iect the sectionsr Ilan-d' l5 maybe `considered as an integral member "for practicalA purposes of construction. The' "sections I5 have ahge portions I6, IG extending outwardlyffr'om the upper edges 'thereof for purposes' which will ybe hereinafterdescribed.

f The support members IL' YH lare placed "in telescopic-end VtoY end relation with each other, aslshown particularly in-Figure Y6, with a struckout portion l1 being fashioned out of the-botf tom wall 'of themember i2 and bent at'right angles thereto, so that it abuts kagainst the purlin' lli. The end ofthe corresponding supportY member Il, which is slightly reduced 'in fully andl better understood 'by refer- -1 is a plan View of a complete unitV l size to fit into telescopic relation with the end of the adjacent member II, has the bottom wall I8 of the section I2 bent upwardly a slight distance so that a locking member I9 is provided which is fitted into the upturned portion I8 of one of the sections I2, with one end 20 turned around the bottom wall at the end of the member I2, and the opposite end 2I of the locking member I9 is bent downward around the purlin III, so that when the longitudinal support members II are placed in position they are held against both longitudinal and vertical movement upon the purlin I0.

Transverse U-shaped channel members 22 are provided which are placed in spaced relation With each other and extend at their ends-substantially up to the side walls of the members I5, I5. Connecting members 23 are provided which have four-way extensions such as 24, 25, 26 and 2'I. The extensions 24 and V26 are formed of the same cross-sectional shape as the members I and of sumcient size to fitV inside these Y members, while the extensions 25 and 2'I are being adapted to cover an area Aenclosed by adjacent pairs of support members `I I, II andthe transverse members 22, 22. 'I'he pans 28fhave downwardly turned'flanges 29 around their entire outer periphery, with horizontally turned edge portions 30, 30 provided so that the edge contour of the pans is substantially of Z-form. In use, the horizontal portion 30 of theY edge of the pan may be omitted, as I may find that the cup members hereinafter described willbe suicient without relying upon these edges to form bases upon which the cup members engage vas hereinafter described. Extending transversely of the pans 28 on the under side thereof are spaced angles 34, 34 terminating short of the edges of the pans to aiord the necessary rigidity to the pans to prevent their bending or cuppingin service and to assist the pans 28 in sustaining weight placed upon them, such as may be 'necessary due to workmen or others walking across the top of the roof during its construction or for purposes of servicing and the like. The pans may have ribs rolled therein to alford sufficient rigidity, if desired, instead of using the angles 34, 34. l

Fibreboards 31, 31 are cemented or otherwise aiiixed to the under side of the pans 28, being of Vsuch length that their ends fit snugly against the flange 28 at eachV side of the pan, and preferably of sufficient thickness so as to re'stV on the flanges I3, I3 of the section II. These boards 3'I are of proper width to be'tted between the angles 34, and are attached to the underside of the pans in the shop prior to being placed in position on a roof, so that these boards become a part of the roong 'unit ready'to' be installed when the supporting frame is completed. Y'They provide protection against condensation onY the under side of the roof, heat and cold insulation and also possess sound deadening qualities, Yall of which is desirable in roofs of this character.

Other materials may be used if desired, such as plastic compounds of various kinds, to perform the function described above.

Fitted to the longitudinal sections I5 and the transverse channels 22 and extending over the edges of the pans 28, are lcap strips 3l, 3l, these cap strips having inverted U-shaped members 32, 32 spot-welded to the under sides thereof. Holes extend through these cap strips 3l and through the members 32 in register withv each other, so that bolts 33, 33 may be placed in the channel sections I5 and the channel members 22, and extend upwardly therefrom to hold the cap strips 3l in position when the structure is assembled.

A corner cap member 35 is provided having extensions extending in four directions from the center thereof, and which is adapted to overlap the ends of the cap members at the corners and the ends of the support members II and transverse members I2 at their ends also. These cap members are held inY position by the bolts 33, 33 which pass through the ends of the longitudinal support members" I5, I5 and the transverse members 22, and also through the extensions of the corner channel sections 24, through the ends of the cap' strips 3I and through openings in the extensions of the members 34. Thus when the members are assembled'and the bolts placed in position, the whole structure is held together in a unitary structure by means ofl these bolts 33, the bolts 33 also holding the cap strips 3I in position at the ends.

In assembling the combination, the longitudinal members II are placed in position' and secured to the -purlins I!) and then the corner sections 24 are placed in position so that at this stage of the assembling the structure is in the condition shown at the upper right-hand vcorner of Figure 1. The bolts 33 at the corner positions may be inserted and then the open sided longitudinal sections I5 'and the transverse sections 22. also the connecting members 23, 'lled with any prepared roong mastic 36, these channel sections and connecting members 23 beingsubstantially lled with this mastic. The pans 28 are then placed in position, with the edges of the pans extending into the mastic inthe-open ichannels, so that in eiect the edges of the 'pans-28 around their entire periphery are seale'din the mastic, preventing Vwater from flowing into the open sides 4of the channels and preserving the portions of the metal with which it comes in contact. f i

The cap strips 3| are then placed inposition over the longitudinal members and the transverse channels, with the U-shaped members projecting downward into these channel sections and preferably resting upon the; horizontaledges of the pans, sothatas the nuts on the bolts 33 are tightened the pans are placed under tension, thus serving to draw the pans taut and hold them rmly in position in service. The cap members 34 are thereupon placed in position as shown at the Vleft end of the figures, so that the-ends of these -members overlap the ends of the cap strips 3l. Nuts are tightened upon the end Ibolts 33 so thatthe cap `strips are firmly held in position, and then theentire surface is coated with a masticor roofing paint, as may be desired, so that the surface of themetal is protectedl from rust and other actions of air'and 'Water coming in contact withit. v Y In following the installation it will be understood that Ithe parts hereinabove described are pre-fabricated and that the initial lst eps comprise 'thellaying of theV longitudinal vsupport 4members and putting the transverse members into shape, andthat'this can be followed by the other steps hereinabove described, so that the installation of a roof can be very easily and quicklyaccomplished. Y

While I have described more vor less. Vprecisely the details of construction, Ido not wish Vto be understood as limiting myself theretdas Iy contemplate changes in form and the proportion of parts and the substitution-of. equivalents as Vcircumstances may suggest or render expedient vwithout departing from the lspirit or scope fof my invention.
