Application filed my .18, 1917. Serial No. 169,386.

To all "whom it may concern Beit known that I, \ViLLiAM H. Evans, a citizen of the United States, and resident of Lakewood, county of Guyahoga, State of Ohio, have invented certain new and useful Improvements in Building Constructions, of which the following is a specification.

This invention relates to building construction and more particularly to floors vide a standardized reinforced concrete beam adapted for use in floors of various load capacities and also adapted for use as studding either in a bearin'g or non-bearing partition.

Other objects and the features of novelty will be apparent from the following description taken in connection with the accompanying drawings, in which,

Figure. 1 is a perspective view of a rein-' forced concrete beam embodying the invention;-

Figs. 2 and 3 are perspective views of dif- I ferent forms of-reinforcement for the beam shown in Fig. 1;

Fig. 4 is a perspective view of a hollow tile or filler block to be used with the beams shown in Fig. 1;

Fig. 5 is a transverse section through a girderand floor slabs embodying the invention;

Fig. 6 is a perspective view of a floor slab embodying the invention;

Fig. 7 isa composite perspective of diiferent types of partition'c'onstruction embodying the invention; and

ig. 8 is a perspective view of a block to be used in connection with the tile shown in Fig. 4:. i u

Referring to] the drawings, 10' indicates,

generally, a concrete forced by two bars 11 and 12, preferably of the form described andclaimed in my ready beam which is rein-- prior application Serial No. 165,149 filed April 28, 1917. The bars 11 and 12 are arranged near the upper and lower sides of, the beam and their ends may project from the concrete, as shown in Fig. 1, for a purpose to be hereinafter described.

The bars 11 and 12 have legs or flanges along two sides thereof and are latticedtogether by bars 13, indicated in dotted lines in Fig. 1. The reinforcement used inFig. 1, is shown more clearly in Fig. 2, th1s form of reinforcement being particularly adapted for floor beams and it will be observed that the construction is such that the beam will have substantially uniform strength irrespective of whether the beam is used in the position shown in Fig. 1 or relatively inverted. The lattice bars 13 may-be riveted or bolted to the bars 11 and-12 and the arrangement shown in Fig. '3 is preferably for reinforcing the studding of a partition, although either of the types of reinforcement shown may be used for beams or studding for cases where uniformity is desired throughout a building.

It will be observed the beam a T-shaped section and'being of such Width that one side of the .beam is s ipstantially double the width of the other si e.

Referring to Fig. 6, it will be observed that the floor slab is made up of a series of beams 10 spaced apart to receive. between them hollowtile or filler blocks 16, shown in detail in Fig. 4. The blocks 16 may be of any suitable construction but should have shoulders and 15 of thebeams and thus support the blocks with their upper and lower faces flush with the upper and lower sides of the beams 10 so that the slab thus built up is to receive the wearing floor on the upper side and the ceiling plaster on the under side. i

In Fig. 5, the manner of erecting a system of flooring is illustrated. A concrete girder 20, is reinforced by a built-up truss comprising the angle bars 21, 22,23 and 24 connected together by lattice bars25 and 26 and spacers 27 and 28 as describedin my prior application #165,149. built-up reinforcement is placed inposition that the beam 10 has shoulders, or ledges 14 and 15, along opposite sides and substantially at the middle of the height of the beam, these giving to p 18 and 19 along the middle of .opposite sides, to engage with the ledges 14 After this the beams.

on its supporting columns, the floor beams 10 are placed in position with ends on the von the job of large quantities of concrete materials, incident to the systems of reinforced concrete construction heretofore used.

Filler blocks 16 are placed between the beams 10 and closure slabs 29 are arranged at the ends of the filler blocks 16 to prevent the cementitious materials, used in the girder 20, from flowing into the chambers in the blocks 16. The closure blocks 29 are shown in detail in Fig. 8. The ends of the bars 11 and 12, projecting from the ends of the beams 10 are connected together, across the girders 20, by tie-rods 30, thereby increasing the strength'and rigidity of the construction. Forms for the concrete, of the girders 20, are then placed in position and the cementitious material laid, the same embedding the ends of beams 10 and filling the space to the level of the top of A floor thus constructed is as strong as the equivalent reinforced concrete floor, as heretofore made, and has the advantage of being of less weight, requiring less materials, a minimum false work, and more rapid construction.

In Fig. 7, I have shown my invention as applied to different types of partition construction. The studs 31, 32, 33 and 34 are Furthermore, the

are ready to receive a plaster or stucco fin-- ish. For a lighter partition the studs may be arranged as 32 and 33 where the spacing is for two of the blocks 16, the studs '32 and 33 being relatively in reverse arrangement to permit the blocks 16 to interlock therewith and together as shown. F or a heavy bearing partition the studs may be arranged side by side in interlocked are'the studs 33 and 34. This arrangement may also be employed to provide a, light column or a very heavy floor may be constructed by arranging the beams in a similar manner.

Having described the invention what is claimed is:

In reinforced concrete floor construction, the combination of a built-up truss forming the reinforcement of a girder, alined concretebeams extending in opposite directions laterally from said truss and having upper and lower reinforcing bars arranged with their ends projecting from the ends of the concrete, said bars being connected together in said beams to form a truss and the ends of the beams being supported directly on the first-mentioned truss, tie rods oppositely connecting the said projecting ends of said up er and lower bars of alined beams toget er across the first-mentioned'truss, and the first-mentioned truss, the ends ofsaid beams and said tie rods being embedded in a monolith.

In testimony whereof I affix my signature.
