CONCRETE FLOOR CONSTRUCTION Filed Oct. 15, 1926 2 Sheets-Sheet 2 VIIIIIIIII WILL/AM M.v GoLosM/m Patented Oct. 1, 1929 UNITED STATES PATENT OFFICE WILLIAM M. GOLDSMITH, OF CINCINNATI, OHIO, ASSIGNOR TO THE GOLDSMITH METAL LATH COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO CONCRETE FLOOR CONSTRUCTION Application filed October 13, 1926.

10 duce a molded ceiling and a molded concrete floor wherein the ceiling and floor are bonded together while the floor is in a plastic state.

Another object of my invention is to provide a concrete floor wherein the reinforcing 15 bars, waste pipes, wiring conduits, etc., may

. be positioned or arranged with a minimum of time and effort and in an expeditious manner.

Serial No. 141,321.

My invention contemplates a temporary flooring or centering 10 supported by the usual uprights or shoring 11. The temporary flooring being erected to cover the entire space over which the ceiling and floor are to be constructed. After the shoring has been erected a suitable bonding element 12 is positioned upon the upper surface 13 of the temporary flooring 10. The bonding element 12 may be a wire frame of an inverted U shape and comprises a body portion 14 having

arms

15 and 16 extending therefrom. The

arms

15 and 16 are bent toward one another at the point 17 whereby to form an inclined portion 18. The

arms

15 and 16 are then bent upon themselves at 19 to form a base 20 whereby to support the bonding element upon the shoring 10. The free ends 21 of the

arms

15 and 16 are then bent right angles to the base 20 and extend in a plane parallel to that portion 22 of the

arms

15 and 16 secured to the body portion 14. This structure provides a way 23 intermediate the free end 21 and portion 22 of the

arms

15 and 16 having a downwardly and inwardly wedged shape cross section 24.

A series of the bonding elements just described may be joined together by suitable bars 25 being secured to the

arms

15 and 16, as shown in the left hand portion of 1. Again, a single bar 26 may be employed, which is secured at 27 to the body portion 14 of the bonding element above described. The

bars

25 and 26 may be secured in any manner to the bonding elements 12 such as by spot welding, soldering or the like, at the

points

27 and 28. By securing the bonding elements 12 together as described above a wire frame results, as disclosed in Fig. 1, that may be readily positioned in a minimum of time and in an expeditious manner.

After these frames have been positioned a suitable cement-itious or plaster ceiling 29 is poured upon the upper surface 13 of the shoring 10, which material enters the way 23 formed intermediate the bent portions of the arms and 16 and surrounds the bonding element from the point 17 downwardly, securely embodying the bonding element within the cementitious material as shown in Fig. 1. The cementitious material 30 intermediate the bent portions of the

arms

15 and 16 forms a key which, after the cementitious material has set, prevents the withdrawal or removal of the bonding frame from the ceiling after the said ceiling 29 has set. After the cementit-ious ceiling 29 has set and hardened itbecomes the finished ceiling of the room under construction. It should be noted that except for a very narrow strip 31 of the base of the bonding element 12 the entire element is concealed from view.

After the ceiling 29 has set the metal domes or hollow tiles 32 are then positioned upon the upper surface 33 of the ceiling 29. The leg 34 of the domes 32 is received intermediate the free end 21 and the portion 22 of the

arms

15 and 16 of the bonding element 12. The free end 21 prevents the inward spreading or bending of the leg 34 of the dome 32 and the portion 2270f the arm 15 prevents the outward spreading of the leg 34 of the dome 32. After the domes 32 have been positioned, the concrete floor 35 may be poured, which enters the space 36 intermediate adjacent domes for forming the beam 37. It is readily evident that the body portion 14 and

arms

15 and 16 secured to the body portion 14 of the bonding element 12, as well as the tie rods and 26, are all embedded in the concrete floor and securely retained in place after the said concrete 35 sets and becomes hard. As stated above, the free end 21 of the

arms

15 and 16 prevents the inward movement of the legs 34 of the domes 32 which might be caused by the pressure of the concrete bearing against the outer surface of the said legs 34. The portion 22 of the

arms

15 and 16 secured to the body portion 14 prevents the outward spread- P mg, as stated above, of the legs 34 due to the pressure of the concrete upon the upper surface of the domes 32.

In the modified structure illustrated in Fig. 7, the free ends 21 of the

arms

15 and 16 have been removed at the upper line of the ceiling 29. This structure may be used where there is no danger of the leg 34 of the domes 32 bending inwardly, or wherein the pressure on the top of the dome may tend to bend the legs outwardly. The portion 22 of the

arms

15 and 16 secured to the body portion 14 prevent such a caving or bending of the dome.

The body portion 14 of the bonding element 12 may have formed intermediate its ends suitable depressions 38 which form a chair for the reinforcing bars 39. The reinforcing bars 39 may be secured to the individual bonding elements 12 and the tie rods or

bars

25 and 26 eliminated. In such a structure the reinforcing bars would serve the double purpose of securing the frames 12 in spaced rela tion as well as performing their normal function, namely, that of reinforcing the concrete.

In Fig. 4 I have illustrated a concrete floor using the bonding element disclosed in the right hand portion of Fig. 1 wherein the metal domes 32 are secured to the portion 22 of the

arms

15 and 16 by means of a tie wire 40. WVith this structure the arms 34 of the metal domes 32 are precluded from collapsing or bending inward from the pressure of the wet concrete in the floor and beams. I have also provided reinforcing bars 41 embedded within the plastic ceiling 29 whereby to reinforce the ceiling 29. It should be noted that when the reinforcing bars 41 are employed the tie rods or

bars

25 and 26 may be eliminated, allowing the bars 41 to serve as a tie means and a reinforcing means.

In Figs. 5 and 6 there is illustrated a channel 42 secured to the

arms

15 and 16 of the bonding element 12 so positioned as to lie on the upper surface 33 of the finished ceiling 29. The channels 42 are adapted to receive the leg 34 of the domes 32 which channel affords continuous support for the bonding element and precludes spreading of the legs 34 of the dome32. It is readily evident that the structure shown in Fig. 5 carries all the necessary means for bondingthe ceiling to the floor, reinforcing the ceiling, reinforcing the beams and floor, and means for insuring the correct position of the domes during and after the pouring of the concrete to form the beams and floor.

It must be readily evident that I have produced a device wherein a finished ceiling and a concrete floor may be erected in a minimum of time and with a minimum of labor. After the ceiling 29 has set the upper surface 33 thereof may be walked upon by the workmen and the like for arranging any waste pipes, reinforcing bars, electric wiring conduits, etc., that it may be desired to place upon such a ceilin It is also evident that the surface may be walked upon for positioning the metal domes 32 and that the danger of injury to the finished surface of the ceiling is absolutely eliminated.

What I claim is:

1. A. combined bar support, tile spacer and key device comprising spaced inverted U shape wire frames having arms for supporting the frames, and for supporting and spacin tiles, and connector members, spacedly securing the frames and providing with the frames, elongated structures for aligning a plurality of adjoining tiles and for gauging adjacent rows of adjoining tiles.

2. A floor in the course of construction, the combination of temporar centering, a plurality of rows of frames, ars connecting and securing the frames of individual rows of frames, the frames comprising key portions disposed at the bottom of the frames, rows of XVILLIAM M. GOLDSMITH.
