Similar characters of reference refer to similar parts and portions throughout the several views of the drawings:

In my building construction I employ a special construction web member as tie members for tying the spaced wall portions together which is shown best in Figs. 6 to 10 inclusive of the drawings. It consists of a metallic strip I of a length to suit its particular use in the building construction and is of a width to suit the thickness of the wall floor, ceiling or roof support. It is provided at its opposite sides with a plurality of prong members Ia which are provided with bevelled ends Ib terminating in a sharp point Is. Each of these prong members is provided with a plurality of integral laterally extending portions Id in each side edge which are preferably punched from the side edges of these prongs and the material is extended laterally to one side as shown best in Figs. 9 and 10 of the drawings. These prong members Ia are bent alternately in opposite directions along both edges so that there are two spaced rows of prongs as shown best in Fig. 7 of the drawings which I have designated I and id and they are preferably formed with curves at their intersections with the body of the strip designated Ie. Inwardly from these prongs at each side of the strips there is provided the depressed or curved portions I j which serve for lateral reenforcing of the web member and prov des greater flexure strength, and between these depressed portions If the. web, strip is provided with a plurality of cutout portions I9 and between the adjacent cutout portions lg are rib portions Ih which are also provided with depressions or reenforcing members Ii as shown best in Figs. 6 and 8 of the drawings which provides for greater iiexure strength than if they were fiat. These web members are utilized for connecting, supporting and reenforcing the spaced wall portions formed of plastic slabs at the opposite sides of the wall, ceiling, roof or floor, as will be hereinafter described.

For certain portions of my construction ll also employ a special strut member 2 which is preferably composed of a relatively thin metallic strip which is principally formed in U shape as at 2a shown best in Fig. 13 of the drawings to provide lateral and fiexure strength. It is provided at each end with a plurality of prongs 2b and 20 which are bent outwardly in opposed direction vfrom each other as shown best in Fig. 21 of the drawings, thus two of the prongs 2b are turned in one direction and the other two prongs 2c are turned in the opposite direction and they are in alternate relation to each other. Each of these prongs are provided with a plurality of punched integral ofiset portions Zdwhich serves as bonds for the plastic material.

I also employ a similar strut member 3 which is constructed the same as the strut member 2 throughout except that the main portion is provided with a plurality of corrugations 3a as shown in Fig. 15 of the drawings, thus providing a modified form of strut member for particular use when desired.

I also have provided a special structural cord web member 4. as shown best in Fig. 20 of the drawings which is the same as one side of the web member l, but only utilizes one side from the holes I g outwardly, the prongs and the depression If being the same construction throughout.

Referring now to Fig. l of the drawings, buildings are constructed substantially as follows: Foundation is laid in the usual or conventional manner with a raised central ridge 5a in the preferred form. The shoulder 51) of the foundation 5 is substantially liush with the base line or ground surface and positioned on this shoulde 5b and on the ground is a relatively thin slab of plastic material, preferably cement 6 and provided with conventional wire net reenforcing 6a. After this slab 6 is laid it is approximately one inch thick. While the concrete is still in a plastic state the web members are set on one side with the prongs Ia embedded in the plastic cement and after the concrete is hardened with these web members extending vertically spaced the proper distance apart, the work of constructing the upper or top slab I is begun, by first laying substantially one inch in thickness and the floor is finished. In erecting the side walls the web members I perform the function of tying the inner and outer slabs t and 9 (which are preferably concrete) together and bracing the same in rigid position, the web members being preferably set in at about sixteen inch centers for the reason that sixteen inches is the normal space for stucco wire netting to span. After these web members I are set and aligned and braced the wire strands are stretched over the inner and outer area of the wall web members as a backing for'the building paper the same as hereindescribed for the top floor slab. The building paper is placed tight over the inner and outer surfaces of the webs and wire strands to form a backing for plastering operation which is accomplished in the conventional manner. These web or connecting members I are also used for forming ceiling and roof supports and areas in the same manner as the floor and wall construction as shown in Fig. 2 of the drawings. I

Referring now to Figs. 16 to 19 inclusive of the drawings, the prongs Ia are used for anchoring the wire strands II! which are stretched over the walls, floors, ceilings or roof areas. The wire strands Eli are drawn tight and the ends wrapped around the prongs as shown best in Fig.16 at varions intervals in order to hold the wire strands Iii tight and the prongs bent over where the wire strands Ill are secured. Building paper II is then placed over these wire strands lb and some of the extended prongs are forced through the paper, thus supporting the paper rigidly in position. Then a few more of the prongs are bent down over the paper to hold it rigidly in position. This is shown in Fig. 17 of the drawings. Then wire netting I2 is stretched over the area to be reenforced (against the building paper as shown in Fig. 18 of the drawings). This wire netting is used for reenforcing of the concrete slabs. Then the cement is laid in the conventional manner as shown in Fig. 19 of the drawings so that the prong members I a form a bond into the concrete slab by projecting into it about the center of the slab and the prongs are not bent snug against the building paper. Therefor a liberal amount of concrete will embed itself in around the prongs as the bent portions of the prongs are approximately at right angles to the face of the web members and are aligned parallel to the line of the concrete slab in which they are embedded and therefore form a positive bond into the concrete slab.

Therefore these prongs Ia perform five important functions: First as an anchorage for the wire strand; second as an anchorage for the building paper; third as *an anchorage for the wire reenforcing and fourth a a bond for the concrete slabyand fifth they form a bracing together with the web portion and tie members for the spaced slabs, either for floor, side wall, ceiling or roof support.

It is believed that the web members I have considerable structural value in whateverposition they are used, but they are not necessarily designed to carry any particular structural value as far as calculated stresses and strains are concerned other than a bracing effect between the connected slabs. The webmembers when placed between two slabs produce a web-like structure to coact with the wall slabs in providing a wall adapted to act as a series of vertical trusses, the web members acting likewise whether placed in a wall, floor or ceiling or roof structure as disclosed herein.

In preparing roof, ceiling and floor construction as shown in Figs. 1 and 4 of the drawings where strut members are used as a level ceiling with pitched roof or a level ceiling with a floor above as in Fig. 4. The prongmembers la'of the cord member 4 and the prong members 2b and 2c of the truss member 2 are interlocked and bent and spread in varying directions and embedded in the cement slabs forming the roof and ceiling or floor and ceiling as shown best in detail in Figs. 11 and 11a of the drawings, thus forming rigid ties between the cords, trusses, and slabs. The cord members] as shown in Fig. 20 of the drawings are used for rafters and ceiling beams as shown in Fig. 1 and as floor joists. and ceiling beams in Fig. 4 of the drawings and the prongs 4a, which are the same as the prongs la in shape and construction, are utilized in the same manner in the slabs forming the roof and ceiling and these slabs forming the roof and celling are interconnected and braced by means of truss membersas shown in either Figs. 12 or 14 in lieu thereof when desired. These truss memi bers 2 are positioned in bracing relation as shown in the roof and ceiling construction in Fig. 1 of the drawings and in the floor and ceiling construction as shown in Fig. 4 of the drawings and the ends 2b and 2c are embedded in the concrete slabs forming the roof and ceiling or floor and ceiling and the members 2b and 2c are spread similar to that shown in Figs. 11 and 11a oi the drawings and provide for rigid .bonding between the slabs and the ends 212 and 2c of the truss members 2. Thus where a level ceiling is constructed in conjunction with a pitched roof as shown in Fig. 1 and the trusses are used to support the ceiling slab and the roof slab is in compression and is deemed to be of'suiiicient strength to support the ceiling slab, both ends of the truss being rigidly secured in the slab and the top and bottom cord members are tied together forming a complete truss, it being noted that the trusses are set in their vertical position to carry their vertical load and others are set at an angle to produce a bracing or trussing effect and that the prongs on the trusses project well into the concrete slab and with the concrete poured around them provides a very efficient conmotion between the trusses and the concrete slab.

It will be here noted that the ends of the wire netting placed in adjacent floors, walls, ceilings, or roof construction are extended from one slab into the adjacent slab so that the ends overlap and form rigid connecting ties between the adjacent slab in either the floors, walls, ceiling or roof construction.

It will be here noted that any form of plastic material may be used for forming the slabs. Any form of wire netting reenforcing may be utilized embedded wholly in the slab. All of the walls are of double slab spaced construction with continuous air space between the two slabs. The walls provide insulation against weather and efficient insulation against transmission of heat.

By varying the width of the web members varying thicknesses of walls may be produced and roof and floor constructions are produced in ub stantially the same way except the concrete is poured instead of plastered or sprayed on the surface.

Though I have shown and described a particular construction, combination and arrangement of parts and portions and certain modifications thereof, I do not wish to be limited to this particular construction, combination and arrangement nor to the modification as herein disclosed, but desire to'include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.
