6 Claims. SICI. i2-70) This invention is directed (to improvements in a concrete' and steel oor construction, which makes it possible to conceal a portion of the cross supporting beams and girders in the flat concrete slab, and which utilizes the steel floor sections between the girders as forms to receive the concrete reproong, with provision for the embedment of the girders within the concrete in the formation of a reinforced monolithic structure.
In carrying out this method of construction, the steel floor sections, in the form of pans, are rigidly attached to the girders. by means of projecting lugs, which serve to unite all portions of the floor structure in such a way as to provide the necessary strength and rigidity and to permit the employment of light weight concrete as a filler, which reduces the dead load of the floor system and affords better flreproong and protection than that afforded by the use of ordinary concrete.
Furthermore, the metallic floor sections, together with the'box shaped girder casings which are united therewith and which provide for the reception of the concrete embedding the girders, in conjunction, provide a smooth uniform finish which requires no plastering, and at the same time-protects the enclosed concrete from disintegration due to fire or other causes.
The present construction is superior to the usual method of reproong the beams Where the concrete slab is poured flush with the top of the beam, and shelf angles are riveted to the web of the beam to carry the slab. It is also superior to the ordinary method of constructing a deck which requires that the steel sections be placed on top of the beams and which renders it necessary in the reproong of the beams to rst build forms around the beams and girders and pour the concrete reprooflng around the beams before placing of the steel floor. Y
In the present invention, the employment of steel floor sections, in the form of open-ended pans, in conjunction with girder shells secured to the pans, permits the pouring of the concrete into the pans by a single continuous operation, from which it will flow into the girder shells 1ocated at a lower level, so that all portions of the metallic frame structure will be embedded within the concrete filling of monolithic character, which eliminates the necessity for the use of temporary pouring forms and greatly simplifies the character of the metallicv reinforcing structure, thus securing the requisite strength and rigidity and permitting the use of light Weight concrete,
with the attendant advantages of such a structure. Y
Further objects andA details will appearV from the description of the invention in conjunction with vthe accompanying drawings, wherein,
Figure 1 is a plan View of one of the oors of a typical building, showing in dotted lines the po'- sition of the girders and pans;
Fig. 2 is an enlarged sectional elevation, taken on line 2 2 of Fig. 1;

Fig. 7 is a similar view, taken'on line 'I 'I of Fig. 1; and
Fig. 8 is a similar view, taken on line 8 8 of Fig. 1.
It will be understood that the building arrangement shoWn is merely illustrative of the principles involved and serves to illustrate varying conditions encountered in the employmentof the features of the present invention.
The building, as shown, comprises side walls I0 and I I, an end wall 'I2 and an inwardlyoffset wall I3. Within the enclosure thus afforded are located what may be referred to as longitudinal girders I4 and intersecting transverse girders I5.
The girders rare supported by columns or the like (not shown) at the points of intersection, where the span is of a length to require interior suppoit, although itwill be understood that such interior support, if used, constitutesV no portion of the present invention, and that, for fairly long spans, the pans of the present invention, in conjunction with the girdersand monolithic concrete filling, will afford sufficient strength and rigidity without intermediate columns or the like.
The vlongitudinal girder I4, as illustrated on the section line 2 2, extends between the walls I0 and Hand is of I-beam formation and cooperates on each side with an open sided, open ended marginal pan I6, the inner open edge of which is welded to the inturned flange I1 of a girder shell I8 of relatively deep troughlike formation, which surrounds the girder and is held in spaced relation on all sides therefromy so as to constitute a pouring form for the complete enclosure and embedment of the girder, being suspended fromthe girder by Z-shaped brackets 3B which are welded to the girder and to the anged edge of the shell. The marginal pans immediately adjacent all of the longitudinal girders are similarly formed, arranged and united to the girder shells, preferably by welding along the overlapped edges, so that, when a concrete or similar plastic lling I9 is poured into the marginal pans, it will flow down into and surround and embed the adjacent girder, thereby forming a monolithic filling within the marginal pans and Ythe girder shell. n
The marginal pans I6, on their outer edges, are provided with side walls 20, whose upper edges are turned inwardly to afford horizontal flanges EI terminating in downturned edge flanges 22. The marginal pans I6 cooperate with a group of parallel elongated open ended intermediate pans 23 having side walls 24 which are inturned to provide horizontal flanges 25 terminating in downturned edge flanges 26 identical with the wall` construction of the marginal pans. The walls thus formed abut together and are preferably united by welding or the like to afford a T shapedl construction which extends throughout the length ofthe abutted pans and affords a series of closely spaced reinforcing elements in the nature of I-beams, in which the bottoms ofV the pans constitute the bottom flanges of the I-beam structure. This arrangement enables relatively long pans to berempIoyed, which run parallel with the longitudinal girders and find end support either from the exterior wallsi or fr omv the interior girders, or from both, as the case may be. j Y
Fig. l illustrates the manner in which the inner ends of a series of pans are supported in unison from one of the interior transverse girders I5. This girder, as shown, is of less depth than the longitudinal girder I4, and is surrounded by a girder shell 2l in all respects like the one rst described, save in the matter of depth, which shell is provided with inturned flanges 28 which afford a shelf or support for the ends of a series of intermediate pans 23 with the accompanying marginal pan I6. The pans are supported from the girders by the employment of short lugs 29, which underlie and are welded to the flanges of the pan and project beyond the ends of the pans in position to rest upon the'upper flanges of the girders to which they are welded, thus suspending the ends of the pans and affording a strong and rigid metallic framework for the reception of the concrete and eliminating the use of shelf angles or the like for the support of concrete slabs.
Where the ends of the pans extend to the exterior wall, asV for instance the wall I in Fig. 5, I provide for their support by partially embedding a girder beam 30 of I-beam formation partially in the wall, so that its lower flanges project outwardly on one side, Withthe lower flange surrounded by a wall girder shell 3l having a bottom 32 terminating in a marginal flange 33 which abuts against the base of the wall vgirder beam and is partially embedded within the wall. The outer wall of the shell terminates in an inturned flange 34` which` furnishes a shelf or support for the ends of the pans, which are additionally supported by Welded lugs 29. As shown, the web of the girder beam 3D is inset sufficiently within the wall so that the concrete filling I9 within the` girder shell will lock into the wall itself, furnishing a rugged anchorage for he ends of the pans. with their concrete filling and serving to tie the,- Wall and floor structures closely-together.
Fig. 6 shows the connection afforded between one of the openY sided marginal pans and the adjacent wall I3. In this case, the lower end of the longitudinal girder I4 shown in Fig. l is embedded within the inner face of the wall section I3, and partially surrounded on its lower inner side by a girder shell 3| identical with that previously described, which is supported by Z- shaped brackets, 36, hooking over the upper flange of the girder, which is the method of supporting the girder shells in all of the various modifications in structure herein described.
Fig. 7 illustrates a construction `which is substantially. identical with that of Fig. 4, save for the fact that the girder shell 2'Ia is formed with lower walls on one side than on the other, to accommodate pans set at different levels on opposite sides` of theV girder to afford a thicker floor construction on the right hand side. In this case I have Vshown hangers 31 for supporting the lower set of pans at the right, While thepans at the left on a higher level are supported by lugs 29; The opposite ends of the pans in Fig. 7 are supported by a wall girder 38 embedded within the wallV I0 and partially surrounded by a shell 3|a similar to the shell 3l, save as to the matter of" depth. In other respects the construction is substantiallyidentical with that shown in Fig. 5.
Fig. 8 shows a construction in which an interiorjwall 39 is employed, as for instance in an elevator shaft, and in which I have. provided a girdervshell 40 having inner and outer side Walls 4I and 42, which' are spaced sufficiently tobridge through the entireV thickness of the wall and whichV surrounds the transverse girder I5. The outer wall 42 terminates inan inturned flange 43', which rests upon a supporting plate 44. overlapping the top ofthe girder, but in other respects the construction of Fig. 8' is similar to that previously described. l l In erecting a floor by the employment of the pans and shellsl of the present invention, the outer walls will be erected of masonry or concretefof the proper height to receive the wall girders which are embedded at the'proper levels, and the interior girders are erected and supported at the ends either by embedment in the walls or by additional interior support, and after the girder skeleton isthus erected, the ends of the pans are hung from and secured to the girders by the lugs welded thereto, and the bottoms of theV pans are supported upon the suspended girder shells and welded, and the abutting walls of the pans are welded together until the entire structure hasbeen united in condition toreceive the concrete-or other plastic filling.
As the concrete is poured into the open ended pans, and also into the open sided marginal pans, it will run down into the girder shells, inasmuch as the pans afford troughs or channels forgdirecting, the flow of concrete around the girders, and after the' girders have been completely embedded, theV pouring of additional concrete will continue until the concrete isof sufficient depth to overlie both the pans and the girdersthereby furnishing an unbroken top layer which extends throughoutthe entire floor and thus affords a substantially monolithic structure, partially divided, however, into slabs'by the abutting walls of the pans, which furnish additional reinforce'- ment throughout all portions of the floor structure. At the same time the edge portions of the floor will be firmly andfcontinuously united and anchored to the exterior walls of the building. The.` @.(sesv offthe pans willbeiirmly. and permanently embedded `within the concrete, and the bottoms of the pans themselves, in conjunction Y, with the girder shells, will affordv the ceiling iinish, which willpresent a smooth and unbroken appearance, save for the joints between the pans and the depending offset form of the girder shells. 'The metallicsurface thus exposed may tended lengths and sizes at the mill, and when so cut, the erection of the building can proceed rapidly and without the necessity for providing forms or scaffolding or other temporary expedients of the character ordinarily required in the pouring of concrete.
Although the invention has been described with particularity as to detail, it will be understood that the description here given relates to typical forms ordinarily employed in the erection of a building in a manner conformable to the present invention, but that various additional modifications may be made without departing from the spirit of the invention.
