This invention relates to teniplets "adapted to. be laid out on the 1 ground or, forinstance, on a i'u 'ndatioil slab, to define? the plan of. a" building that about to be-erected.
teinpletdefinesthe postion of, and mayform part or; shuttering for moulding concrete walls. In other cases it defines and may form part of; the wall itself; particularly when the latter is a hollow wall of a' portable building composed ofv panels connected and supported edgewi'se; I tmpl'et accordingv to thexinvention, Consists or 'n assembly ofmanufacturedunits adaptedto' be smbled in various combinations to-accord withftheshape and size of the walls of. the building."1he assemblycomprises continuity structi'ii' -e'ssential units ot-which are cornerrunits consisting'of two-arms rigidly'extending from one another at right anglesg or suchiother angles-as the building may require. f -There:are two types of corner unit's, one'type inwhich the .visible surfacesof the'walls-to be erected form ahollow or" exterior-angle of less than 180 which in;the.
following specification and claims I, designate as "re-entrant fand the other type in which the vislble' surfaces form: a. protruding ior-exterior,
angle of more than 180 and which I, designate as f's'alient in accordance with the use with;
polygons. 'I n the case of corn'er;.units for reentrant angles, agusset or. the, likeis provided.
for' making the angle rigid. The templet further includes structure that, in;the assemblyldefines thefstraightwalls between pairs :of corners and joins thecorner units in aicircuit which is usually ai'fclose'd circuit. Said continuity. structure thus,
includes the arms of'the corner units and also includes separate straight bars that come between two such arms in line. There are also-coupling units for joining the parts composin thecon-v tiifuityflstructure and'ranging' said parts in.
straightlines. The coupling and corner units and the -straight bars are so formed that the coupling unitsare capable of being'engaged with bothcor' In some T cases zthei said: 'templet sets a Union of South Africa Application February 14, 1945, serial No. 577,898 In-' the Union of South Africa MarchB, 1944 apart from one another.
According to a further feature formed ofpanels having'edge formations con-v structed toengage edgewise with similar panels and other parts of walls; and the templet' is formed with an upward edge or surface that'interengages or'inte'rlocks with the lower edge for-- mations of panels or wall units laid on it. Sa'id inter-engaging formations are'usually of the generaltongue-and-groove type. V 1 a The means whereby the abovementioned ties engage with the respective tern-plot sets is prefer.-
ably such that upon layingthe ties with their ends properly positioned on the templet, .the
superimposition of the wall panels on the templet automatically secures the ties to the templet with the'innerand outer sets of the latter properly.
spaced apart and tied together bythe ties. With this object the ends of the ties are shaped in cross section to engage with the aforesaid intereng'aging or interlocking edge or surfaceforma-' tionsp The invention is illustrated in the accompanye ing drawings in which:
Figure I is a plan view of a templet for a tworoorned building.
Figure II is a perspective view illustratingthe used the templet. Figure III is an enlarged cross section through a bar Gand coupling 1. l I The 'temple't shown in both-Figures I and andfindicated' generally by 2, defines the plan shape of'two parallel sets of walls, which maybe for instance the two elements of the hollow wall of a portable building, or the inner and outer shuttering walls temporarily set up to mould. a
concrete wall between them. There are accords;
ingly at least two templet sets viz; an outer set indicated by letter A and an inner set indicated by letter B.' Each room of the'buildinghas, its own inner templet set; the second inner templet set in the illustrated example being indicated by B 'Each templet set forms a closed circuit. 3
Each templet set comprises corner units indicated by the numeral 3 and consistin of two arms rigidlyfixed to one another at right; angles-ear in some other angular relationshipin; the unusualcase of a building that is not rectan-s gular; The corner units of the inner-set B or B are principally for defining re-en'trant corners between the walls. Such 're-entrant cornerunitg .areindicatedbyj and their arms 4 ar made space the latter properly a of the invention; the templet-is incorporated in and forms the footing'of walls erected on it. Said walls may be" tight and telescopically on the adjacent ends of the arms 4 and of the bars 6 and are long enough to hold said parts firmly in line across the joints between them.
The whole of the continuity structure, which includes the arms 4 of the corner units. and the separate bars 6, is formed of sheet metal pressed to a common cross sectional shape which imparts longitudinal stiffness and provides a base that stands stably on a hat surface. The section shown enlarged in Figure III includes that of a upwardly directed tongue 8 of a tongue-androove connection, the ends 9, 9 of which provide the stable base. The coupling units 1 are also made of sheet metal pressed to a cross sectional form that enables them to connect the arms 4 and bars 6 telescopically; and if the bar and arm section is of a formdescribed later-that is suitable, the units are made of the same section as the bars and arms. In using the term the same sectipn it is assumed that the sheet metal is sufficiently thin relatively to the dimensions of the section for there to be no significant difference between the internal and the, external profiles of the section.
When the templet comprises two or more templet sets, it also includes ties it, the function of which is to connect the similar elements of the sets and to hold said similar elements parallel with one another and properly spaced apart ac-.
cording to the overall thicknes of the buildin walls to be formed. The ties here shown are similar to those disclosed in Union of South Africa patent specification No. 1,121 of 1943. They con-v sist oi fiat strips of sheet metal havin end portions ll bent to form a tongue section that is transverse to the length of the tie, and that fits the tongue 8. The length of the ties corresponds to the intended overall thickness of the wall to be formed; and may vary accordingly as the. wall is an outer wall or a partition wall.
In order to make use of the templet in th preferred manner, a level foundation surface 12 (Figures I and II) is. prepared, by for instance building a concrete foundation l3 for th building. It is convenient to assemble one of the templet sets first; say set B. To do this a corner unit 3% is laid down and a bar 6 is attached to each of its arms 4 by the couplings 1. Other bars. are similarly jointed on as may be necessary; the couplings keeping the bars and armsv alined at their joints. A corner element is added at the end of each line thus formed; the telescopic char-. actor of the joints enabling said lines to be adjusted to length with precision. The process is continued until the circuit of the set B is completed. The set B is similarly completed; and, the parallel elements -m and n of the two sets, B, B are connected by several ties l0. These ties, are laid transversely to the continuity structure and with their end portions. ll engaged either under or over the barsv 6 and arms. 4 and so that their tongue shapes nest into the-tongue shapes of said bars and arms.
The inner sets B and B having been thus assembled, more ties ID are engaged with said sets at intervals and directed outwardly. The outer set A is now assembled in the same way as the inner sets and in addition so as to engage with the outer ends of the last mentioned ties. Since the inner ends of the ties are already engaged with the inner sets, the mere engagement of the outer set units with the outer ends of the ties causes said outer set to be positioned parallel with and properly spaced from the inner sets, without further measurement.
The corner units and especially the gusseted corner units .s are important in determining the squareness of the layout; and if some lack of squareness has appeared during the assembly, haking the assembled templet, by enabling elastically bent parts to straighten out, will usually ensure complete squareness all through the layout.
The templet thus assembled may be employed in various ways to impart. its form to the walls of the intended building. The lower course of blocks of a concrete block wall, for instance, may be cor-J rectly laid out by setting said blocks in the space,
engage edgewise. Said panels are indicated in igure II by 1 4.. Their loweredges are, shaped as a tongue-.andegroove formation complementai to that of the arms 4 and bars 6; and in the ex-. ample shown as a somewhat V-shaped groove. The upper edges of the. paneis are also of tongue and groove formation; and said upper edges of the two wall elements are tied. and spaced by ties indicated by [5. The drawing also shows waling' members [6 interposed between the panel courses as described in patent. application No. 1,120 of 1 943; andit is pointed out that the templet arms, 4 and bars 6 perform a functionsimilarto that of. said waling' members. in. keeping the, lower edges of horizontally adjacent panels in alinement. The panels l4, in turn, duplicate the aliningz function of the coupling members 1., where the. former cross the joints of, they bars; 5 and-arms. 4.-
The two parallel. walls and Y: thus formed, by the panels may, as mentioned above, be. the two elements of a. hollow wall. in which the templet and; the ties. remain as. perm nen fea ures.- Equali y Well they may be the inner and outfit. walls. of-shutterins, between which. a concrete wallj s oulded as su g ted at. ln'tbatc se, the panels. 14 and the. parts; of the templet, are dis? assembled, after the. wall I1 is, formed" and can be reassembled an indefinite number of times; The ties it}, andv 15, remain embedded in the concrete.
In order fi makethe section of thearms 4, the bars 6 and the coupling 1 one that is telescopic in the sense of the outer one of a coupled pair of such members embracing the inner one, at least as long as the sections are not. purposely rotated relatively to one another, there isv added. to the tongue section already described, the fur,- thersection element consisting-of the straight limb. l8 extending-upward-irom one side of the general: V section and hooked over at I59 at its upper end; towards such V section; but this-specific formlis'a not-claimed in this application. Thelimb t8... Larisa provided at the outer edges of the arms 4; and the bars 6 are so arranged when assembled that said limb is also at their outer sides, as appears from the drawings. This allows the moulding faces of the panels M, when the latter are shuttering panels, to extend practically down to the foundation face l2; being separated therefrom only by the thin edges 21 of the templet sections.
