Tho insito rizil forming; the toy member of the 'tleg .which is made unnecessary by the use of the complementary sheet metal elements which will be hereafter described, is utilized to the tullfest extent without any waste. As shown particularly in Figs. l and 2 the slabs 22 may be arranged to space` each of the tiles 2O from the other so as to provide two sets of intersecting channels for the recept-ion of `the tension zone, are the sheet metal elements 25, a preferred form being shown in Fig. 5. The sheet metal elements extend over the top of the tile elements resting on the webs 2l and are formed with side members or'iianges 2G whichstand at rightangles te thewebs 21 and close the open ends ot' the channels of the tiles. Preferably the side members ot the sheet metal elements are formed with inturned rims' 27 which are notched as indicated at 28 so that they extend into the spaces between the webs 21 ot the tile elements. The tile element is preferably formed with three or more upstanding webs 217 the drawings showing tour, the outer pair ot webs forming two sides oi the closed hollow unit, the inner pair, if the tile is provided'with two webs, intermediate the side webs `constituting supports for the sheet metal top to keep the same- 'from sagging under the load of the concrete or trom being bent in by the work .men who. as a usual thing, have occasion to wall; over the tile work before the concrete poured.

ln Fig. 6 l have shown a modified form of tile element 29 which ditlers 'from that shown in Fig. 4 in being provided with theY struck in points or lugs 33, which bear against the ui'is'tanding webs 21 of the tile 20.

Figs. 9 and 10 show the sheet metal element which is the same as that shown in Figs. 7 and 8 except that the points or lugs, here designated 34, arev turned in the oppo direction.

The above described construction has several distinct advantages over an all tile structure. In' some localities at least it is cheaper to make the upper elements of the units of sheet metal than ofitile. If the elel ments oi? the Hoor structure have to be lransportml any considerable distance from the place et manufacture to the place where they are used the freight and cartage on the sheet metal is, of course, much less than on the4 tile. The loss by breakage, which is a very considerable item in all tile structures, is very much reduced. An advantage which is more important perhaps than any of these is that my structure is considerably lighter than an all tile structure. As 'a matter of fact the structure of my invention can be made so that it will weigh only about twothirds as much as an all tile structure having units of the same dimensions. As a result the dead weight of the floor is lessened by just so much which permits the use of less concrete, metal reinforcements of smaller diameter which, besides effecting a saving in the` materials constituting the Hoor, makes it possible ,to lighten the sup porting structures on which the Hoor is carried. Thus the cost of the construction of the building as a whole is diminished due to lightening the floor or doors in the tension zone. Furthermore a closer fit can be obtained between a' sheet metal element and a tile element, because of the Hexiloility of the former, than is possible to obtain where the unit is made up or" two engaging or interlocking tiles. Tiles cannot'be made with anything like geometrical precision. Some irregularity necessaril results from the character ot' the materlal ,used and the `fact .that more or less shrinkage and distortion is sure to take place in the kiln. I When the concrete is poured into the` channels, which are formed in part by the lianges or side members of the sheet metal elements, these flanges are pressed snugly against the ends of the tile elements so that leakage of the concrete into the hol'lows of the units is effectively prevented.

Any of hestructures shown inFigs. 6 to 10 inclusive mightbe used in the arrange* ments illustrated in the first three iigures and it is quite possible that modified forms both of the tile element and the sheet metal element could be devised for accomplishing equivalent results in much the same sort of way. Therefore l do not limit myself to the exact constructions,` arrangements and devices shown and described except in so far as certain ot' the same are made llimitations in certain of the claims herein; the intention being to claim(,.both broadly and narrowly Whatever patentable invention there may be in the constructions which I have devised in view of the state of the prior art.

I claim: 1

1. ln a reinforced concrete licor, a strucH ture to subserve the purposes 'of the usual tile work' consisting ot lower tile elements having flatbases and upstanding webs and `upper sheet metal elements having top members resting on said webs and iiangcs projecting downwardly from the top members and closing the spaces between the ends ot' said ""bs, and fiat spacing slabs arranged between the tile elements to space the same apart so as to constitute channels for concrete and metal reinforcements.

2. In a reinforced concrete floor, a structure to subserve the purposes of the usual tile work consisting of lower tile elements having fiat bases and upstanding webs and upper sheet metal elements having top members resting on said Webs and flanges projecting downwardly from the top members and closing the spaces between the ends of said webs so as to 'form hollow boX- like structures closed on all sides,` and spacing; elements which space said box-like structures apart to constitute channels for concrete and metal reinforcements.

3. In a structural unit for concrete oors and the like, a tile element composed of a base, side members spaced apart and one or more intermediate supporting members combined with a sheet metal element comprisin a top which rests upon said side members and intermediate 4support or supports, and side members which close the Spaces between Sail sido. members.

4f. ln a structural unit for concrete floors and the like, a. tile element composed of a base and a plurality of upstanding webs parallel to each other, combined with a l sheet metal element comprising a top which rests upon said webs, and side members which close the spaces between the yends of said webs. 5. In a reinforced concrete iloor a structure to snbserve the purposes of the usual tile work composed of a plurality of units each comprising a lower tile element having a base and a plurality of upstanding Webs7 and an upper sheetmetal element having a top and side members, which latter close the spaces between the ends of said Webs; said units providing closed box-like structures arranged in the Aioor in parallel rows and spaced apart so as to provide two sets of intersecting channels adapted to receive concrete and metal reinforcements.
