Description

April 3, 1934. F. M. VENZIE 1,953,203

' BUILDIIENG CONSTRUCTION Filed June 16, 1932 ATTORNEY Patented Apr. 3, 1934 UNITED STATES PATENT FFICE 9 Claims.

This invention, generally stated, relates to a building construction havingparticular relation to a cementitious slab foruse in a fioor structure.

One object of the present invention is to provide a simple, eflicient, andrelatively inexpensive slab of fire-proofing nature which is strong and durable, having the partsso arranged that companion slabs may be coupled or tied one with another both longitudinally and laterally considered in order to provide maximum stability.

Another object of the present invention is to provide an arrangement, combination, and connection of parts for attaining the results sought by the foregoing object.

With these and other objects in view, the invention consists of the novel structure hereinafter described and. finally claimed.

The nature, characteristic features and scope of. the invention will be more fully understood from the following description taken in connection with the accompanying drawing forming part thereof, and in which:

Fig. 1 is a top or plan view of the main or supporting metal structure of the slab prior to pouring the cementitious material;

Fig. 2 is an end view thereof Fig.3 is an end view of the completed slab;

:Fig. 4 is a view in longitudinal section of a pairfof llpositioned slabs;

Fig. 5 is a top or plan view of one of the slabs shown in Figs. 3 and 4; and

Fig. disa fragmentary view in plan illustrating the manner of coupling or tying together companion slab parts at a juncture point.

For the purpose of illustrating my invention I have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumenta1ities as herein shown and described.

Referring to the drawing in detail, the reference numeral 10 designates parallel side pieces formed of T-irons, with the longitudinal flanges 11 thereof facing inwardly. At desired intervals throughout the extent of the side pieces 10 the flanges are apertured at 12. Having hooked relation as at 13 with certain of the apertures 12 are a series of spaced cross-rods 14. Extending longitudinally of the ladder-like frame thus provided are spaced rods 15 which have laced or intertwined relation with the cross-rods 14, best seen in Fig. l. The terminals of the longitudinal rods 15 are lip-turned as at 16, see Fig. 2, so that in assembled position of the respective. slabs said terminals may be tied together as at 17, see Fig. 4. The above described frame is embedded in a floor slab 18 of cementitious material, as clearly shown in Figs. 3, 1, and 5 The and through apertures in the slabs in alignment with apertures 12 and the free ends of the wires twisted together to interlock companion slabs with respect to one another at junction points of said slabs.

What is claimed is: l r a 1. An article of the character stated comprising a pre-cast slab of cementitious material having embedded therein a reinforcing frame made up of parallel side-pieces of T-iron the inwardly extended flanges of which frame are connected by cross-rods to form a ladder-like configuration, longitudinal rods connecting with said cross-rods in intertwined fashion, the terminals of said longitudinal rods being upturned and projected beyond the slab ends.

2. An article'of the character stated comprising a pre-castslab of cementitious material having embedded therein a reinforcing frame made up of parallel side-pieces of T iron the inwardly extended flanges of which frame are connected in hooked relation by cross rods to form a ladderlike configuration, longitudinal rods connecting with said cross-rods in intertwined fashion, the termiturned and projected beyond the slab bevelled ends.

4. An article of the character stated comprising a pre-cast slab of cementitious material having embedded therein a reinforcing frame made up of parallel side-pieces of T-iron the inwardly extended flanges of which frame are connected by cross-rods to form a ladder-like configuration, the flanges of said T-iron being apertured at intervals to accommodate tie-wires, longitudinal rods connecting with said cross-rods in intertwined fashion, the terminals of said longitudinal rods being up-turned and projected beyond the slab ends. I

5. In a building construction suitably supported pre-cast slabs having bevelled ends each slab having embedded therein a metal frame made up of side rails and longitudinal and laterally disposed rods, the latter having intertwined relation, the terminals of the longitudinal rods being up turned and projected through the bevelled ends of the slabs, the rod terminals of adjacent slabs being tied together in the space afforded by said end bevels.

6. In a building construction suitably supported pre-cast slabs having bevelled ends each slab having embedded therein a metal frame made up of side rails and longitudinal and laterally disposed rods,the latter having intertwined relation, the terminals of the longitudinal rods being up-turned and projected through the bevelled ends of the slabs, the rod terminals of adjacent slabs being tied together in the space afforded "by said end bevels, said side rails and slabs being apertured in alignment, and means for tying together adjacent slabs through said apertured portions.

7. A precast building slab comprising a cementitious shape, means for reinforcing said shape,

said reinforcing means comprising metal edges for two sides of said shape, said metal edges defining a surface lying in a plane at right angles to metal edges providing means for connecting other coupling means to said shape, and said shape having a bevelled surface between an edge of said metal edge and a major surface and a corresponding bevel on the edges of said shape not having a metal edge whereby in assembled position said connecting means may be located between the two major surfaces of said shape while the edges of said shape may abut.

-8. A precast building slab comprising a cementitious shape, means for reinforcing said shape, said reinforcing means comprising metal edges for two sides of said shape, said metal edges defining a surface lying in a plane at right angles to the major surface of said shape and providing means for holding other reinforcing members in position, said other reinforcing members comprising means for connecting adjacent shapes; and said shape having a bevelled surface between an edge of said metal edge and a major surface and a corresponding bevel on the edges of said shape not having a metal edge whereby in assembled position said connecting means may be located between the two major surfaces of said shape while the edges of said shape may abut.

9. A precast building slab comprising a cementitious shape, means for reinforcing said shape, said reinforcing means comprising metal edges for two sides of said shape, said metal edges defining a surface lying in a plane at right angles to the major surface of said shape and providing means extending into said slab for reinforcing edges of said slab and for holding other reinforcing members in position between the two major surfaces thereof, said other reinforcing members comprising means for connecting adjacent shapes; said metal edges providing means for connecting other coupling means to said shape, and said shape having a bevelled surface between an edge of said metal edge and a major surface and a corresponding bevel on the edges of said shape not having a metal edge whereby in assembled position said connecting means may be locatedbetween the two major surfaces of said shape while the edges of said shape may abut.
