' Patented July 28, 1931 UNITED STATES PATENT OFFICE HERBERT E. WHITE, 01 YOUNGSTOWN, OHIO, ASSIGNOR TO TRUSCON STEEL COMPANY, OF YOUNGSTOWN, OHIO, A. CORPORATION OF MICHIGAN manure one: srmrorunn Application filed October 26, 1928. Serial No. 815,311.

One of the objects of the present invention is to provide a metallic roof deck or similar structure that can be quickly and conveniently assembled and fastened in place 5 without the necessity of the workmen operating beneath the deck. A further and important object is to provide novel fastening means that will efiectively hold the parts in place and can be utilized in connection with 1 ordinary commercial structural members. A still further object is to provide novel means for producing a joint between abutting ends of the deck members or sections.

In the accompanying drawings:

Figure 1 is a plan View of a portion of a roof deck constructed in accordance with the present invention.

Figure 2 is a cross sectional view of the same.

Figure 5 is a plan view of the joint piece.

Figure 7 is a view in elevation of a yoke of said clip.

Figure 8 is an edge view of such yoke.

In the embodiment disclosed, supporting members or purlins are employed that may be channel beams. One of these is shown at 9. The same is located on edge to provide a horizontally disposed flan e 10, which flange as is well known, normally tapers from the web to its free edge. This tapered formation is made use of as hereinafter explained.

Supported onthe purlins 9 and extending transversely thereof is a deck formed of sheet metal strips or members designated generally by the reference numeral 11. These members, each comprises a body or top wall 12 with side walls 13 and 14 formed by flanging the margins of the metal. of the side walls, as 13,, is provided with an outstanding terminal rib or flange 15. The other side wall 14 is also provided with a terminal outstanding flange 16 preferably wider than the flange 15, and joined to the side wall by an inwardly extending bead 17.

minate short of the ends of the plate 19,

One 7 This bead produces a groove 18 at the bottom of the side wall 14 and above the flange 16 (see Fig. 6). In laying the structure, the members 11 are located side by side, as shown in Figure 2, with the flange 15 of one member fitting into the recess or groove 18 of the next adjacent.

These members are held-in place by the following clip structures. At each purlin'9 a cl1p plate 19 is placed on the flange 10 thereof, so that it lies on said flange 10 and overlies the flange 16. To position it, said plate is preferably provided with a downturned portion 20, the ends of which terforming abutment stops 21. The plate is thus reversible and can be employed irrespective of the direction in which the flange?" 10 of the purlin extends. The plate 19 is gripped to the purlin 9 by a yoke element 22 that embraces the flange 10 and plate 19, and is preferably provided with mturned spurs 23. This yoke ma have a driving head 24. The distance between the free ends of the spurs 23 is preferablysuch that the spurs will fit upon the free margin of the flange 10, but as this flange increasesin width toward the web 9, it will be evident that the yoke must be driven into place, so that the spurs 23 will bite into the underside of the flange 10 and the upper side of the plate 19, thus effectively holding all the parts in place.

In laying the members 11, it will be noted that when one is placed .in position, the flange 16 thereof is exposed and that consequently the workman may stand or kneel upon this section, place the plates 19 .over the exposed flange 16, and drive the yokes home He thus does not have to work or operate beneath the member. When he has fastened the same down, the next member is placed over the fasteners by inserting the flange 15 into the groove 18. This brings the flange 16 thereof in exposed position to be fastened and the operation is of course repeated until the deck is laid. It will be observed in this connection that the end of the plate 19 terminates short of the side wall 14, so as to permit the introduction of the flange 15 into the groove 18. While the strips or members 11 may be formed of relatively great length, it becomes necessary at times to use two or more in one rowthat is, end to end, and a novel joint is provided for this purpose, as illustrated in Figures 1, 3 and 4. The ends of the adjacent members 11 are slightly separated and a channeled joint piece 25 has its ends fitted into the adjacent ends of said members 11 and bridges the space between them. This joint piece is preferabl formed of sheet metal bent to channel 0rn1,vwith its end portions preferably inset as shown at 26 to permit its ready insertion. The downturned ends 27 of the joint piece rest respectively on the bead 17 and flanges l6. The central portion of the joint piece is provided with a transverse rib 27 that fills the space between the ends of the adjacent sections 11 and is in substantial alinement therewith.

Where the end of the deck abuts a wall or other obstruction, the space between one member 11. and the wall may be less than the width of the members, in which case the structure shown in Figures 1 and 2 may be employed. The wall herein is indicated at 28. Abutting the Wall is a section of one member, as illustrated at 29. It is provided with the side wall 14, the flange 16 and bead 17. In other'words, it may be an ordinary member cut longitudinally and of course can be cut diagonally if the wall is diagonal to the direction of the deck members 11. In the space between the wall 14: and the first standard member 11 is a bridge piece, comprising a top wall 30 having a. depending wall 31 provided with a flange 32 fitting in the socket or groove of the bead 17. The top wall 30 may overlie the adjacent standard member 11 and be secured thereto by screws 33 or other fasteners. This, however, would ordinarily provide a single supporting wall 13 that would make a weak point in the deck structure. In order to overcome this difficulty, a reenforcing wall 34 may be employed corresponding in all respects to the wall 14 with its flange 16 and bead 17 of a standard member. This is fitted into place and held by clips corresponding to those already described.

As already shown this deck structure can be laid without the workmen either lying over the top and working underneath or Working upwardly from beneath because the-fasteners when placed are ex osed and readily available from the tops of the deck already laid. 'Further than this, a smooth deck or floor is provided on which heat insulating material and a roof body can be placed. The structure is very strong since it is supported by a double side wall at each point and this it will be noted is true even where an obstructing wall or termination requires a special arrangement. The

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
