Patented Dec. 20, 1932 UNITED, STATES FREDERICK M. VENZIE, F PHILADELPHIA, PENNSYLVANIA FLOOR STRUCTURE Y Application led November 18, 1931. Serial No'. 575,838.

This invention, generally stated, relates to a building construction and has more particular relation to flooring made up of precast slabs which may be either of waterproof- I ing material perse or provided with `a coatf ing or layer of waterproofing materia-l..

One object of the present invention is to provide a simple, eicient, and comparatively inexpensive arrangement of parts for the rapid assembling by unskilled labor of liooring possessed of Waterproofing characteristics.

A further object of the present invention is to provide an arrangement and construction of parts of the character stated in which adjacent Vpre-cast slabs are tied or coupled together by means of reinforcing rods or wires longitudinally considered.

A further object of the present invention is to provide a pre-castfslab of the character stated the under surface of which is provided with spaced, pendant, integral flanges which flanges have embedded therein longitudinally extended reinforcing rods the terminals of which rods extend beyond the slab ends for clinching with reinforcing rods of adjacent slabs.

A further object of the present invention isto providea structure of the character stated in which there is provided intermediate adjacent slabs a vertically arranged apertured web for interlocking adjacent slab ends with respect to floor beams constituting part of the floor structure.

A still further object of the present invention resides in the providing of general details of structure and arrangement of parts as will hereinafter more fully appear.

The invention consists ofthe novel construction hereinafter more fully described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description 45 taken in connection with the accompanying drawing forming part hereof,` and in which: Fig. 1 is a view, principally in longitudinal section of flooring embodying the invention; Fig. 2 is a fragmentary view in plan of the part shown in Fg- 1S Fig. 3 is a fragmentary view of the underl vside of the part shown in Fig. 2;

Fig. 4 isan end view, partly in section, of Fig. 2; y Fig. V5 is a view in side elevation of Fig. 3;

Fig. 6 is a fragmentarypview illustrating the manner of tying together the reinforcing rods shown in Fig. 1;

Fig. 7 is a fragmentary view in elevation hereinafter referred to;` y

Fig. 8 is a view in section taken upon the line88 of Fig. 7; and y Fig. 9 is a view in perspective of a tie piece hereinafter referred to. f

For the purpose of illustrating my invention I'have shown in theaccompanying draw v ing one form thereof which is at present v preferred by me, since thel same has been found in practice togive satisfactory and reliable results, although it isto be understoody that the various instrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as here- 75 in shown and described. v

Referring to the drawing inV detail, the reference numeral 10 designates spaced floor members as I-beams for supporting the novel lpre-cast slabs 11 embodying the invention. 80 These slabs 11 maybe made of anysuitable material, preferably possessingwaterproofing characteristics. Each slab 11 is provided uponits under face and formed integral therewith with pendant, longitudinally eX- tended ribs 12, as best seen in Figs. 3, L1, and 5. Embedded in each rib 12 is a longitudinally extended member 13, as a rod or wire. VThe ribs 12, as before stated, are arranged in spaced relation and the ends thereof are bevelled ,as at 14. Each reinforcing member 13 throughout the maj or portion of its extent parallels the bottom of a slab as clearly shown in Fig.` 1. Each reinforcing member at its ends is vdeflected upwardly atan angle Y15, 95

see l, and thereafter is extended outwardly as at 16 in a horizontal mannerto parallel the major :portion-of the eXtentof Y said reinforcingV member, fand is thereafter extended upwardly in parallelism asiat 17, as 100 best seen in Fig. 1. The object in having the ends of the reinforcing member extended as at 17 is that of providing means whereby a tie wire 18 may be adjusted with respect to the up-turned ends of the reinforcing member to couple the precast slabs together, as best seen in Fig. 6.

rllhe central rib of each slab has embedded therein a vertically extended plate 19 apertured as shown in Fig. 5 to lighten construction. This plate extends from the central rib upwardly and terminates short of the top of a slab as shown in Fig. 4. Both the upper and lower portions of said plate are flanged as at 20. y

Adjacent the abutting portions of the floor slabs there is provided a device as best yseen* in Fig. 9 which is made of wire and comprises .a cross piece .1 and appair of parallel prongs 22. In practice these prongs 22 are introduced through one end 'of aV floor slab, as best seen in Fig. l, and the ends of the prongs 22 are turned over as at 23 beneath the flanges of a. iloor beam 10. In the connection it is to be noted that the cross bar 2l of this device, as best seen in Fig. 8, is embedded in the slab material. The yabove construction anchors the floor slab with respectto the floor beams l0. In practice a cementitious flooring material 2i is applied over the flooring slabs il.

In order to accommodate the cross bars 21 the slabs lll are notched as at 25.

The slabs 1l in order kto provide lateral interconnection are notched as at 26 and provided with a rib 27 opposite to the notch 26 whereby the slabs may be interlocked one with respect to another. y

What is claimed is:

l. In a building construction of the character stated, flanged floor beams, pre-cast slabs the ends of which are cuty away to lit over the upper flanges of and be supported by said beams, said slabs having embedded therein longitudinally extended reinforcing rods, the terminals of which rods extend first through the slab ends at an upwardly extending angle entirely free of the beam flange and thereafter are extended vertically beyond a slab end, means for tying together the vertically extended portions of said reinforcing rods of companion slabs, a. cementitious fill .covering said slabs including said coupled together ends of said reinforcing rods, each slab beingprovided laterally considered with a notched portion, and a tie-piece accommodated in said notched portions the terminals of said tie-pieces being clamped beneath the undersides of the beam flanges.

2. In a building construction of the character stated, flanged floor beams, pre-cast slabs the ends of which are cut away to fit over the upper flanges of and be supported by said beams, said slabs being` provided with `:pendant spaced -langes each flange having i,s91,51's

embedded therein longitudinally extended reinforcing rods, the terminals of which rods extend first through the slab ends at an upwardly extending angle entirely free of the beam flange and thereafter are extended vertically beyond a slab end, means for tying together the vertically extended portions of said reinforcing rods of companion slabs, a cementitious fill covering said slabs including said coupled together ends of said reinforcing rods, and an apertured and flanged reinforcing plate embedded in each of said slabs and extendedinto an intermediate of said flanges. f

3. In a building construction of the character stated, flanged floor beams, pre-cast slabs the vends of which Iare cut away to 'it over the upper flanges 'of and be supported by said beams, said slabs being provided with pendant yspaced flanges each flange having embedded therein longitudinally extended reinforcing rods, the terminals of which rods extend first through the slabfends at an'upwardly extending Vangle ventirely free of the beam flange-and thereafter are extended vertically beyond a slab end, means for tying together the vertically extended portions of said reinforcing rods of companion slabs, a cementitious fill covering said slabs including said coupled together ends of said reinforcing rods, andan aper-tured and flanged reinforcing plate embedded in each of said slabs and extended into an intermediate of said flanges,the said reinforcing rods following the general vcontour of said reinforcing plate. e

4. In a building construction of the character stated, met-allie floor supports, pre-cast slabs the ends of which are cut away toit over the V-up'per flanges of and be supported by said beams, said slabs being provided with pendant spaced flanges each flange having embedded therein longitudinally extended reinforcing rods, the terminals of which rods extend first thru the slab ends at an upwardly extending angle entirely free of the beam flange and thereafter areextended vertically beyond a slab end, means for tying together the vertically extended portions of said reinforcing rods of companion slabs, a ce- '115 mentitious fill covering said slabs including said coupled together ends -of said reinforcing rods, and anaper-tured and flanged reinforcing plate embedded in each of said slabs and extended into lan intermediate of vsaid flanges.
