Patented May 5, 1931 rATVENT oFFicE YEIREDFRICK M. VENZIE, PHILADIIIQIEHIAL,4 PENNSYLVANIA BUILDING STRUCTURE Application `meer J'ulyza, 1929;` serial No. 380,276.

This invention, l a building construction and has more particular relation to a floor structure. It is common practice in building construction l where I-beams are employed to leave the saine exposed with the exception of a slight covering of cement, so that the contour of the ceiling 1s interrupted at intervals by these beams.

The leading object of thepresent invention is to overcome this disadvantageous feature and provide a structure in which the I-beams are entirely concealed vbetween the floor surfaces and the ceilingV surfaces.

A further object of the` present invention is to provide a series of hollow tiles spaced between adjacent I-beams, each tile being ofA a height inY excess of the height of ani-beam. A furtherobjvec't of theV present invention is to provide a cap ffor each hollow tile so that in the pour of the `concrete none of it enters the hollow tiles.

A further object of. the present inven tion is to provide a hollow tile of the character stated which is by ribs. v

lA further object of the present invention Y p l in Figs.v 3 and 4, a detail description of which is to provide a tile ofthe character stated provided at its lower end with a flanged' part having ribs upon two faces `and Vgrooves upon the other two faces so that adjacent tiles .may interlock. i i* Y A still further object of the'present invern tion is to provide a' tile of the character stated the flanged part. of which has fupwardlypr jected therefrom a generally7 rectangular portion eXteriorly provided with, ribs sov that a bond may be formed between the tiles yandV the concrete. l

With these and other objects in View, the

invention consists of the novel construction hereinafter described and finally? claimed.

The nature, characteristic features' and scope of the invention will be more fully un-V derstood from the following descriptionv taken in connection with the accompanying drawings forming part hereof, and in which Fig. l, is a view in cross section. of a floor and ceiling structure embodying the invens l" tion, taken upon ne une 1mi of rig. e.

For the purpose of illustrating my inventionI have shown in the accompanying drawings oneform thereof which is at present preferred by Ine 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 vorganization of the instrumentalities as herein shown and described. Y

Referringto the drawings in detail, the reference numeral l designates an I-bea1n as used between a floor 2 and ceiling 3.v VIn forming the structure after the I-beams are in place the usual scaffold .or support, not shown in the drawings, is used to temporarily support the pour of concrete. Upon such temporary support between adjacent I-bealns are positioned a plurality of tiles 4, best seen one of the will hereinafter appear. These tilesare hollow and are arranged to receive at their tops a plate or cover 5. When the tiles are positioned as shown in Figs. land 2, a concrete j fill` 6 is introduced between adjacent tiles, as

clearly shown in Figs. l and 2. The concrete iillmay have introduced therein reinforcing rods 7. With the concrete properly set the-V temporary scaffold is removed and a coating ofceiling plaster is added. By this arrangekment and construction of parts it is noted that the I-beam is completely concealed from view, and that the ceiling has a plane surface -f and is notinterrupted by unsightly obstructions.

Taking up now specifically the construction of a tile, and referring more particularly to Figs. Sande, the reference numeral 8 designates a lower flanged portion, forming a solid base, Awhich terminates in an upwardly extending hollow member 9. Two faces of the has@ 8 areprovidefl Witbribs l0 and the other two faces are provided with channels 11. By this arrangement of parts the bases of adjacent tiles may have interloclred relation as clearly shown in Fig. l, it being understood in this connection that wherever a beam 1 is present the meeting edges of a pair of adjacent tiles completely cover the bottom of the beam 1. The hollow member 9 of the tile is eX- tei'iorly provided with ribs 12 so that a bond may be formed between the concrete 6 and the tiles. The tiles are provided with reinforcing rods 13 at their tops and with reinforcing rods lll in the base of the tiles, as best seen in Fig. 1. The tile is interiorly provided with a reinforcing construction consisting of vertically disposed cross ribs 15 and 16, which ribs stop short of the upper edge of a tile to provide a ledge 17. This ledge 17 affords means to receive the plate or cover 5.

The above arrangement and construction of parts forms a very eflicient and relatively inexpensive structure which greatly enhances the appearance of a room since the ceiling contour presents a plane surface. The tiles may be manufactured at a plant and shipped to destination ready for installation, and these tiles may be installed by unskilled labor, which is a very desirable feature.

Another advantage resides in the fact that I am enabled to obtain a uniform plastering surface throughout the ceiling. This is because of the fact that the plaster boards provide a plastering surface which is uniform so that stains, as frequently appear upon ceiling surfaces from above, are eliminated.

I am aware that the invention may be embodied in other specific forms without depart ing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

VJhat I claim is:

1. A floor structure having completely concealed beams comprising spaced beams, a plurality of hollow tiles arranged between adjacent beams, each tile having a flanged solid base and recessed at its top to receive a cover plate, adjacent bases abutting with the flanged parts of at least some of the tile bases completely covering a beam bottom, the tops of said tiles being substantially flush with the tops of said beams, a cover plate for each hollow tile, and cementitious material arranged between said tiles.

2. A floor structure having completely concealed beams comprising spaced beams, a plurality of hollow tiles arranged between adjacent beams each tile having a flanged solid base and recessed at its top to receive a cover plate, adjacent bases abutting in interlocked relation with the flanged parts of at least some of the tile bases completely covering a beam bottom, the tops of said tiles being substantially flush with the tops of said beams, a cover plate for each hollow tile, and cementitious material arranged between said tiles.

3. A door structure having completely concealed beams comprising spaced beams, a plurality of internally reinforced hollow tiles arranged between adjacent beams, each tile having a flanged solid base and recessed at its top to receive a cover plate, adjacent bases abutting with the flanged parts of at least some of the tile bases completely covering a beam bottom, the tops of said tiles being substantially flush with the tops of said beams, a cover plate for each hollow tile, and cementitious material arranged between said tiles.

4. A floor structure having completely concealed beams comprising spaced beams, a plurality of hollow tiles arranged between adjacent beams, each tile having a flanged solid base and recessed at its top to receive a cover plate and vertically disposed portions eX- teriorly provided with a plurality of ribs, adjacent bases abutting with the flanged parts of at least some of the tile bases completely covering a beam bottom, the tops of said tiles being substantially flush with the tops of said beams, a cover plate for each hollow tile, and cementitious material arranged between said tiles.
