To construct a roof or other horizontal Fig. 12 a sectional elevational view illustratpartition of the tile beam as shown in Fig. 1, ing bolted ends of a pair of beams supported on they are assembled in the manner shown in Fig. an I-beam: 2 with the tongues and grooves 8 and 9 of ad- 55 jacent tile interacting in the manner shown. A mortar or other substance may be poured or otherwise interposed in the tonguesand grooves to provide an uninterrupted finished surface. When assembling the beams as shown in Fig. 2, they are preferably staggered as shown in Fig. 5 to displace the ends of the tie-rods relative to each other, thereby reducing the space between the ends of the beams to a minimum.

As shown in Figs. 1 and 2, the beams are assembled on I-beams I5, and after assembly constitute a unitary floor, roof or other partition member.

While the tile and beam assembly shown in Figs. 1 to 5 inclusive are especially adapted for roof construction, the principle of the invention may be applied in the construction of roofs or ceilings having a plain uninterrupted surface. To this end, the form of tile and manner of assembly illustrated in Figs. 6 to 15 inclusive may be employed, the form shown in Figs. 6 and '7 having upper and lower plain surfaces I6 and II which constitute a floor and ceiling, respectively, or a roof and ceiling, as the'case may be. These tile are provided with straight abutting faces l8, Fig. 6, and I9 Fig. '7', the faces l8 being recessed at 20 and the faces l9 beveled at 2| so that in assembly they form spaces or grooves for grout 22, which is poured therein in a semi-liquid state. The tile of Fig. 6 is provided with a single central perforation 23 for receiving the tie-rods 5, the end face of the tile being recessed at 24, Figs. 10 and 12, to receive the ends of the juxtaposed tie rods when the beams in which the tile are formed are assembled on the I-beams I5. The recesses may be at both ends of the tile, as shown in Fig. 13, so that the ends of the beams may be assembled on the I-beams without staggering, as shown in Fig. 5, and without interference of the tie-rod ends. In the form of construction of tile of Fig. 7, perforations 25 are provided in pairs to receive the tie rods in the manner of the T-shaped tile of Figs. 1 to 5 and a central web 26 is provided with a slotted opening 21, which constitutes a line of cleavage along which the tile may be supplied.

Figs. 8 and 9 illustrate the uninterrupted surface tiles of Figs. 6 and 7 provided with tongues and grooves 28 and 29, respectively, for interlocking the assembled beams when placed upon the I-beam supports. The tile of Figs. 8 and 9 are also provided with the recesses 20 and bevels 2|, which form a space for pouring grout after the assembled beams are mounted in cooperative abutting relation on the building and supports.

Although several embodiments of the invention are herein shown and described, it will be evident to those skilled in the art that other structural shapes may be utilized. The double T-shape shown in the drawings provides for large compression stresses at the top of the building unit to counteract the tension of the reenforcing members therein, which are preferably located at the bottom of the unit.

I claim:

1. A building unit comprising a plurality of tile block having an uninterrupted surface on one side and channeled on the opposite side thereof, the legs of the channel portion being perforated, tie-rods disposed through the perforations of said blocks spaced from the walls of said blocks and extending the full length of the plurality of blocks to constitute reenforcement therein, filler material interposed adjacent the end faces of said blocks out of contact with the body of said rods, and means on said tierods for drawing said blocks against said filler material to constitute said blocks and rods a unitary beam.

2. A building unit comprising a plurality of tile block having an uninterrupted surface on one side and channeled on the opposite side thereof, the legs of the channel portion being perforated, tie-rods disposed through the perforations of said blocks spaced from the walls of said blocks and extending the full length of the plurality of blocks to constitute reenforcement therein, resilient gaskets of the cross-sectional shape of the blocks interposed adjacent the end faces of said blocks and spaced from said tierods, and means on said tie-rods for drawing said blocks against said gaskets to constitute said blocks and rods a unitary beam.

3. A building unit comprising a plurality of tile block having plain, top and end faces and a cross section of structural shape, said tile having longitudinal voids for receiving tie-rods common to all of said tile, filler material interposed adjacent the end faces only of said tile and tie-rods for joining said tile extending through said voids and filler material, said rods being of less cross-sectional dimension than the voids in the tile and having screw threaded ends for receiving screw nuts, and washers of relatively large diameter disposed between the nuts and end faces of the tile to distribute the compressive strain over a relatively large area of said tile.
