BUILDING CONSTRUCTION Filed May l, 1935 2 SheetS-Sheet 2 Patented Mar. 9, 1937 UNITED STATES PATENT; ori-ics 6 Claims.

This invention relates to building constructions and refers more particularly to fabricated building constructions composed of prefashioned units.

One of the principal objects of this invention is to improve generally building constructions of the type set forth, by providing framework having weight supporting structural elements spaced from each other to permit sliding prefashioned units of convenient size therebetween in such a manner that the units are not only guided, but are also held in assembled relation by the structural elements and, in addition, by providing the units with portions overlapping the exterior surfaces of the elements. The foregoing is particularly advantageous in constructions where the preformed units are of lreproof material, such as concrete, since it protects the weight supporting structural elements from intensive heat and thereby prevents buckling of the elements.

Another advantageous feature of the present invention consists in the provision of a building construction having weight supporting columns and having door supporting elements secured to, but spaced from the columns a sufficient distance to provide for extending portions of the prefashioned units along the inner sides of the columns, as Well as along the outer sides thereof.

A further object of the present invention resides in the provision of a building construction of the character previously set forth rendering it possible to preform the window, door and chimney openings in the units, prior to securing the latter in assembled relation with the structural elements of the building.

The foregoing, as well as other objects, will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure 1 is a fragmentary horizontal sectional view through a portion of a building constructed in accordance with this invention;

Figure 2 is a cross sectional view taken on the line 2-2 of Figure l;

Figure 3 is a cross sectional View taken on the line 3-3 of Figure l; and

Figure 4 is a semi-diagrammatical elevational view illustrating the manner in which one wall of a building may be assembled in accordance with this invention. In Figure 1 of the drawings, the reference numeral I0 designates one side wall assembly of the building, while the' reference numeral II indicates another side wall assembly and the numeral I2 indicates the door structure supported by the wall assemblies. In the present instance, the wall assemblies are iireproof and are built-up from steel structural elements I3 and prefashioned units I4. The steel structural elements I3 are the principal load carrying members and are preferably, although not necessarily in the form of H-section columns, while the units I4 are in the form of pre-cast concrete slabs.

As shown particularly in Figure 4, the H-section columns I3 are secured at the lower ends to the footing I5 in predetermined spaced relationship with the sides of the H disposed in planes parallel to the planes of the inner and outer surfaces of the associated slabs I4. As will be observed from Figure 1, the space between adjacent columns I3 is so determined as to provide for sliding a slab I4 therebetween, in such ,a manner that the opposite sides of the H of each of the columns serves to guide the slabs in place. In this connection, it is to be noted that the opposite vertical edges of the slabs Hare recessed as at I6 throughout the length thereof, to provide for receiving the columns I3. The width of the recesses I6 is suciently greater than the width of the columns for readily sliding the slabs in place between adjacent columns, and the depth of the recesses is so determined that the recess in the edge of one slab will cooperate with the recess in the edge of the adjacent slab to substantially enclose the intervening column. After the slabs Il are assembled with the columns, and are properly positioned with respect to each other, the spaces around the columns are filled with concrete or some other suitable filler by pouring the same into the recesses I6. This construction provides for substantially completely embedding the columns in the side walls of the building and, in addition, serves to integrally secure the concrete slabs together. Embedding the weight supporting columns in a lire-proof material such as concrete, is extremely advantageous insofar as re hazard is concerned, in that it shields the columns from intensive heat and, as a consequence, prevents failure of the side walls by buckling of the columns.

One particular type of corner construction is also shown in Figure 1, and as will be observed embodies an H-section column Il identical in construction to the columns I3 previously described. However, in view of the fact that the side wall I I extends at substantially right angles to the wall I0, the end slab I8 of the former wall is guided in place by an angular structural element I9 having one flange secured to the H- section column, and having the other flange extending in the direction of the slab I8 for engagement in the recess 20 formed in the adjacent edge of the slab I8. The recess 2I in the end slab 22 of the wall I 8 is identical to the recess 20 in the slab I8, and both the recesses are for the same ,purpose as the recesses I6 described above. In other words, the end slab 22 of the wall I0 is guided in place by the opposite sides of the H- section column I1 in the same manner as the slab Il is guided, and the end slab I8 of the wall I I is guided in place by the angle strip I8 welded or otherwise permanently secured to the H-section I1. However, the outer walls of the recesses 20 and 2| are extended to compensate for the corner, and the space defined by the recesses is illled with concrete or other suitable material in the same manner as the recesses I6 are lled.

As previously stated, the floor structure I2 is also supported from the H-section columns, and this is accomplished in the present instance by the following- Y construction. The floor structure is designated in the drawings by the reference character I2 and is secured to the columns, by means of gusset plates 25. As shown particularly in Figure 1, the gusset plate 25 associated with each H-section column is disposed in the same plane as the bar of the H, and the outer edge thereof is Welded throughout the length to the inner side of the H-section. The gusset plates 25 extend inwardly beyond the walls through the spaces provided between adjacent slabs and are bolted or otherwise suitably secured to the floor structure. In connection with the wall I0, the inner portion of each gusset plate is secured to a structural element of I-shaped cross section, which forms one of the floor beams and is supported with the web 21 lying in a vertical plane. In detail, the inner portion of each gusset plate overlaps the outer end portion of the web 21, and is bolted or otherwise permanently secured thereto in the field. 'I'he outer ends of the I-beams 26 are interconnected, by means of inwardly opening substantially channel-shaped struts 28 secured to the webs 21 of the I-beams, by means of suitable angle brackets 29. The floor or I- beam adjacent the wall II is connected to the outer end of a floor channel 30, by means of a strut 8l identical in construction to the strut 28,

and having the opposite ends, respectively, permanently secured to the oor channel and I- beam by means of angle brackets 32. The floor channel 30 is spaced inwardly from the wall II, in the same manner as the strut 28, and is secured to the H-section column I'I at the corner, by means of one of the gusset plates 25, in the same manner as the I-beams 26 are secured to the columns I3. It may be pointed out in this connection that the gusset plates 25 for securing the floor channel 30 to the columns embedded in the wall II differ in detail from the gusset plates employed in connection with the wall I0, in that the inner ends of the former are bent laterally to provide attaching flanges 35, and the latter are bolted to the outer surface of the base of the floor channel 38.

Thus from the foregoing, it will be observed that I have provided a fabricated building construction composed of preformed units capable of being expediently erected at a minimum cost and including wall sections having the desired door and window openings prefashioned therein. It will also be apparent from my improved construction previously described, that the columns or weight supporting structural elements are thoroughly protected from intensive heat and, as a consequence, will not buckle readily in case of fire.
