solaim's. (c1. v2-ssi l My invention Arelates to structural'iioors and ceilings and refers particularly. to liireproof oors A and ceilings. f Y
The usual method employed for the production of hollow reproof floorsand ceilings is to erect a metallic skeleton to -form theV hollow spaces, erect a temporary, or false, ceiling tosupport the plastic material until it has set, or hardened, and
then removethe temporary ceiling. 'i Thereis considerable expense inmaterial and time incident to the erection and remcvalof .this false, or temporary ceiling, and delay is occasioned in the erection of the permanent ceiling as the temporary ceiling can not be removed until the plastic material has set. Y
My invention .overcomes the abovementioned, and other, objectionable 'features incident to the present employed methods o'f'oorconstruction, as it obviates the necessity of `temporarxnor false,
` ceilings and allows of the erection of the permanent ceiling prior tc the absolute hardening of the plastic material employed. Y The several valuable features of the device of my invention will be evident upon a consideration of my specification and accompanying drawings.
` In thefaccompanying drawings showing modied formsjof the device of my invention, similar parts are designated by similarv numerals.'

modiiied Figure 12 is an enlargedperspective view ofthe lFigure 14 is a section through the line 14-14 of Figure 13. i' f y Figure 15 is a perspective view of a modified formnof the device of Figure13.
The particular constructionshown in'Figures 60 Y 1, v5, 6, '7` and 11 comprises a plurality of parallel spaced I beams 20,20. A plurality of hooks 21, 21, are vsuspended from 4the lower flange ofeach beam and a plurality of transverse parallel rods 22, 22, are supported by saidhooks21, 21. V`Wire lath 23, '23, then laidupon the rods 22, 22 and supported thereby. A plurality'A of inverted elongated itin pans 24, 24, are then-positioned upon the wire lath 23, 23, between the I beams. The'iianges 25, 25, of the tin pans have aplurality 70 of openings26, 26, and their up`turned ends 27,
V27, are clamped together by means of the clamps `28,28.T'Ihe`upper iianges of the I beams carry Ya plurality of upwardly extended supports 29, 29,
having a' plurality of openings Y30, 30 therein. 75 Supported by the supports 29, 29, of each I beam and spaced from the'bottom thereof is a sleeper 3 1. It will thus be seen that the entire construction thus formed is supported by the I beams and that it has been erected without the necessity of a temporary ooring. Concrete, or other desirableA material, 100'is then poured in, which 'passes through the openings 26, 26, and theopenings 30, '30, thus forminga solid'concrete mass,y
completely covering the I beams, the upper faces of the tin pansand the sleepers withv the exception of theirr upper faces. vThe upper face of the concrete can then be levelledand the flooring 32 laid, and the ceiling 33`plastered. -f
The modied'form of constructionshown in 90 Figures2, 5, 9, 10"and 12 comprises a plurality of spaced parallel bar joists 34, 34. The lower bar. joists 34', 34, Hcarry a plurality of suspended hooks `35, 35, carrying the-rods 22, ` 22vthe metal lath 23, 23 and the tinpans 24 as previously described. 95 The upperbar joists carry a plurality of upwardly extended supports 36, 36, each having aL plurality 'of Vopenings 37, 37, therein. `Supported @by each set ofupwardly extended supports 36, 36, is a sleeper 38. Concrete, or other suitable material, 100 is poured into the device thus constructed until it reaches the lower:V faces of the sleepers 38, 38. yThe flooring 39 and the ceiling 40y are lthen introduced. In this construction there is an air space 41, between the Yflooring 39 and the 105 upper face of the cement 100. Y
Thefmodied form of construction shown -in Figures 3,:5, 13 and 14 comprises a pluralityfof spaced parallel : Ibeams 42, 42. The'lower flanges 'of eachV I beam carry a plurality of suspended 110 plates 43, 43, having a plurality of openings 44, 44, therein. A plurality of spaced parallel rods 45, 45, are passed through openings 44, 44, of the plates 43, 43. In order to prevent accidental movement of the rods 45, 45, they are notched, a cut out portion 43 of the plate 43 being positioned in a rod notch. Attached to the suspending plates 43, 43, of each I beam 42 isa sleeper 46. Wall boards 47, 47, are attached to the lower faces of the sleepers46, 46, by means of the finish trims 48, 48, which can be done either before or after the concrete 100 is poured.
Concrete, or other desirable material, 100 is then poured until it reaches a height above the top iianges of the I beams 42, 42, and a concrete, or other suitable flooring, 49 is laid.
The modified form of construction shown in Figure 4, is similar to that shown in Figure' except that it contains a plurality of reinforcing rods 50, 50, carried by the upper flanges of the I beams 42, and insulating board 51, 51, is carried by the rods 45, 45, and a plaster ceiling 52 is applied.
The form of support shown in Figure 8 is a modification of that shown in Figure 6, the latter being constructed to support a sleeper parallel to the Ibeam while that shown in the gure is constructed to support a sleeper atright anglesv to the beam.
The form of suspending hook shown in Figure 15 is a modification of that shown in Figure 13, the latter being adapted for useY with I beams while that shown in this figure is adapted for employment With bar joists53.
It will thus be seen that in the construction of floors of my invention, the tin pan, or mold, is supported by supporting means extending from Vjoist to joist and that at no time is it necessary to erect a temporary, or false, ceiling, and, further, that the permanent ceiling may be constructed without waiting for the plastic material to be absolutely hard, or set.
It will be further noted, that my invention allows of a floor construction capable of adaptation to variousshapes and character of metal skeletons, molds, and joists.
I do not limit myself to the particular size. shape, number, form, arrangement or material of parts as shown and described as these are given simply as a means for clearly explaining my invention.
