nels are designed to receii'e metal reinforcements and concrete material. the latter closingthe hollowv spaces in the endsI ot the blocks and producing beams which extend in one direction only in the lloor, 'a'. e, at right angles to the girders. Manifestly, in the latter form of construction tbe'tile blocks are not enveloped on all their sides with the material forming' the concrete ribs. and said blocks are not. and cannot be. conibined `with the concrete material to secure the 'full compressive strength of the hollow blocks in the construction oi the floor oi arch.

According to my invention, I employc crossing or intersecting metal reinforceing rods which constitute tension members at thc bottom middle portion ot lthe door, hollow tile blocks of cellular form internally and open at the respective ends thereof, said blocks being individually spaced with respect to every other block and occupying a predetermined spaced relation tothe crossing metal reinforcements so that the tile blocks are positioned in rows both lengthwise and crosswiseof the resulting floor, and bondingI material composed of concrete which is poured and tamped so as to fill the spaces intervening the sides and ends ot the hollow. tile blocks, whereby the concrete nia- A tei'ial producesintersecting beams which'en-A velop the side walls and end portions of the hollow tile blocks, so as to secure a perfect bond between the dry material of preferably baked hollow tiles and the wet'plast-ic or' Asemi-plastic concrete, such bond existing not only at the side walls of the individual tiles but also at the end faces of said tiles. Furthermore, the cellular hollow tiles and the material of the concrete beams are inti- 'inately loclzedand-bound together for the reason that the concrete material, while in its plastic or semi-pla`stic condition, will enter and fill the hollow spaces of said tiles at the vopen ends thereof, but the. extent of entry ot' such concrete material will not be unduly excessive for several4 reasons, first, the male ial will flow into the open ended spaces to an extent limited and determined by the angle of repose of such material, sccond, by the cross sectional area of' the openings or` the cell spaces at the end of the tile block, and third, by the resistance to the inflow due to the friction between the lwalls of the a1-ll space and the plastic concrete mate- 'the concrete material. thus entering the cell spaces at theopen ends of the tile block results not only in a perfect bond beti'ecn such material but it secures the added advantages oi", i'irst, a mechanical lock betui-een the concrete beam and the hollow tile block, second, the material thus adn'iitted to theends ot the cell spaces 1n conjunction with thc concrete material 1n external con- 4tact with the respective side walls of the tile block coperate in laterally strengthening the walls of thc block so as to impart added strength and resistin qualities laterally to the blocks. and, thir't the tile blocks are so combined with the concrete beams as to attain the Jfull compressive strength of said tile blocks in the floor construction, whereby there' results a floor structure char acterized by an increase of fully fifteen perv cent. in strength with a decrease of not less than ten per cent. in weight of materialsas compared with any prior floor structure of which I have knowledge.

In a practical form of construction the` floor is in the form of a flat slab the concrete material of which is integral with a belt course, said concrete material extending continuously over the tops ot the piers and interior columns whereby I am enabled to secure the important function of continuous floors between the girders and over the topsl ol. theppiers and columns. .Furthern1ore, the metal reinforcing rods or bars are embedded in the vconcrete beams, and said bars-or rods are so positioned that at the middle 'of the Hoor between the girders and piers (at the lsa bottom chord of the fiat arch) the rods act as tension members whereas the tile blocks` and concrete ribs are in compression at the'.

top chord of the arch; but in'carryingY the continuous metal rods or bars over the capitals of the piers or columns, the said rods or bars are at or near the top of the concrete slabs over-,such piers or columns, so that they resist the tension ofthe slab at the top chord' at the specified` particular points.

Other features and advantages of the in-v4 vent-ion will appear from the following detailed descriptiontaken in connection with the drawings.

Said piers andi columns may be of any suitable or preferred construction, but preferably they are formed of reinforced concrete. The' columns and the piers are constructed with enlarged upper ends or zcapitals, as indicated'at 10eand 11l in Fig. course 16, thus the prodiiyion of thus affording wide bearingsffor the floor a solid concrete slab w ch secures creased V strength at the oints where increased v The lloor is a dat slab composedof constrength is uire ,owing tothe strains in- 3 crate 12, i.l1ing blocks 14,.and metal reincident to the oad upon the door.

hollow tile filling blocks 14 are while at the columns and at the belt course emitted o ver the columns and the piers and the top chord of the floor slab is in tension stehe points where the door meets the and the bottom chord is in compression. f. As

At the top portions of the floor slab exposed to the greatest stress the bars or rods are positioned in Overlapping relation, thus f imparting increased strength at such points of overlap. Thus, at the slabs 12, and at the solid concrete slabs between the columns, the ends of the bars or rods are extended past each other, thereby doubling the effect of the reinforce at such points. Furthermore, the'overlapping ofthe rods or bars is effected at all the lines running between the columns within the interior of the building, producing reinforce areas in the nature of internal girders reaching from column to column, thereby bracing and strengthening the building into a rigidunitary structure. Obviously, the walls of the building do not form any part ot' the present invention and are not illustrated. As hereinbefore stated, the building is particularly adapted for manufacturing and business purposes, andas is usual in such cases the Walls are usually skeletonized allowing the largestjpossible window area to insure a Well lighted interior.

In installing the arch the reinforce and the hollow tile blocks are positioned substantially as shown in Fig. l, the reinforce being put into place during or immediately before the tamping of the concrete. lt is preferred to'position the metallic rods or bars in crossing relationv and immediately thereafter to place the hollow tile blocks in the'spaces between said crossing bars and at regular uniformdistances therefrom. As is usual inthe art, the hollow tile blocks are supported by a centering and the rods and bars having been properly positioned, 'the concrete in a plastic or semi-plastic condi. tion' is poured .into the spaces between the rows of' tiles, such concrete being tamped in place. The plastic or semi-plastic concrete 'is in direct contact with the side'walls and ends of the tile blocks so as to secure a perfeet bonding effect therewith, and by tamping the concrete material in place the mass is solidilied to a certain extent andsome of Y the concrete flows into the cells or spaces at the respective open ends of the hollow tiles` the 'extentol entry ot' the plastic or sentii-v plastic material being limited, first, by the angle of repose ofsuch material, second, by the relatively small cross sectional area' of the cell spaces within the hollow tiles, andV third by the resistance due to the frictional contact betweei'i the walls of the cell spaces and the inflowing material. lllhenthe con crete sets and harde-ns a net-work of intersecting ribs results, which ribs are so inti mately united to the sides andgends ofthe hollow tile blocks as to resultin a homogeneous sti-notare. Furthermore, the hollow tile blocks are so united to the '.zOIMSrete beams as to utilize A the full compressive strength of the material in the tile blocks,

and while the tile blocks tend to decrease the dead weight of the Hoor slab, yet said tile" blocks and the metal reinforcing rods are so combined with the concrete beams as to-rey sult in a. monolithic structure possesslng y great weight-carrying or load resistlngcaf pacity. Furthermore, the Walls and partitions of the tile blocks are in contact with the concrete ribs and the inwardlyextending projections of 'such ribs so that the Walls and the partitions of the tile blocks are laterally reinforced, thus materially strengthvching the blocks themselves and adding weight-resisting capacity thereto.

In addition to the foregoing functions, the floor slabr'of my invention possesses other numerous advantages. The structure is extremely light in weight vand easy of installation, for the reason that the centering or molds in which the work is shaped may be perfectly dat owing to the fact that the botv tom of the floor slab is flat. .This effects a great saving, for the reason that the hollow tile blocks may be placed in position on the centering and the rods or bars placed in the desired relation to the tile blocks by unskilled labor, the operation of assembling the blocks `and the rods being rapidly performed, after which it is only necessary to dump the concrete material into place and to tamp such concrete material.

In some prior floor slabs thehollow blocks have been arranged so that there was a vlack of iii-m connection between said hollow blocks and the concrete material, resulting i I I grial interlocked with the open end portions of the blocks, but said material is perfectly bonded with the-filling blocks at the side walls and at the ends of said blocks, whereby the blocks operate etfectually as compres,- sion members, and the concrete material in such intimate Contact with the side walls ,imparts strength and stability thereto for resisting the lateral strains. l v

As will be noted by reference to Fig. 3,'

the partition walls within the hollen7 tiler blocks are close enough to each other to sub? stantially limit the extent to which the plastic concrete material will enter the cells or'V spaces within said block, and by varying the area of such cells or spaces the extent of the teria tersecting concrete beams in-.contact with to .provide entry of. the' concrete materiali-intothe lsanne maybe controlled. ,t isvmypm'p .E roportion the cells or *within the oaks that the concrete*v material willyeliterj 5 to an extent determined lbythe angle of re posev of the' materialandtof the 'de` s ired rm interlockin e gement osaid concrete material 'wi e lli blocks,
