United States Patent METAL BUILDING CONSTRUiITION Earl Franklin Cross, Birmingham, Mich, assignor to The R. C. Mahon Company, Detroit, Micln, a corporation of Michigan Application June 1, 1954, Serial No. 433,649 2 Claims. (c1. res-c4 This invention relates to metal walls, particularly insulated steel walls built up out of sheet metal sections and straps which we call horizontal girts. The channel sections, which form the inside sheeting of the walls, are put together successively after the fiberglass insulation has been placed in the channels formed by the outside metal sections.

The girts are held in place by novel D clips which permit the same gauge metal in the D clip to be arc welded to the 16 or 18 gauge metal in the outside metal channel sections. These D clips are are welded above and below the girts which each D clip bridges to hold the girts in place on the ribs. This D clip and this method of securing the girts in place is a great improvement over welding the heavy girt stock to the ribs or securing the girts to the ribs in some other fashion. These clips distribute the weight of the horizontal girts over a greater area of the outside Wall structure. These clips are so designed as to allow for vertical and horizontal expansion of the building steel and metal wall. The clips have holes which are further apart than the width of the horizontal girt, thereby after welding at the holes reinforcing the ribs and allowing for greater welding area. They provide positive fastening both top and bottom of the clip for the metal of girts and the ribs.

Referring to the drawings:

Fig. 1 is a fragmentary perspective view of the outside wall structure taken from inside, showing the D clip welded to the vertical rib and supporting one of the horizontal girts.

Figs. 2, 3 and 4 are side, front and top elevations of the D clip, respectively.

Fig. 5 is a fragmentary perspective showing the outside wall channel sections looped together.

Fig. 6 is a fragmentary elevation of the outside wall structure after the insulation has been put in place and the girts secured to the vertical ribs by the D clips.

Fig. 7 is a section on the line 7-7 of Fig. 6.

Fig. 8 is a fragmentary elevation of the wall structure showing how the inside wall channel sections are secured in place by the hangers.

Fig. 9 is a perspective of one of the hangers.

Fig. 10 is a top fragmentary plan view of the assembled wall structure.

The outside Wall sections are designated 1. They comprise sheet metal channels with a plan flange 2 at one side and a looped flange at the other side. These fit together as shown in Figs. 1 and 5 to form the vertical ribs 4. The looped flange and the plain flange that forms the rib are fastened together by peening at 20. This makes a plain flush face for the outside of the wall. The ribs form effective reinforcements on the inside of the wall. Heat insulation material, such as fiberglass slabs 5, are fitted into the channels. The D clip 7 is set to straddle the rib above and below the girt 6 and to bridge it. The

Patented Feb. 3, 1959 friction of the clips straddling the ribs will hold the girts in place before welding. Or to insure more friction, nubs may be peened in the sides of the clips. An arc welder then welds the D clip 7 to the vertical ribs at the spots 8 and 9 above and below the girt 6. Slots 10 and 11 in the back of the D clip 7 give access for the welders electrode to contact both the D clip 7 and the back of the rib, thereby making both these members acessible for the electrode metal to unite the two parts together.

When all the D clips 7 have been set over the intersections and welded in place, the inside metal wall structure is set in place. The inside wall sections are what might be termed triple channels. They have two narrow channels 12 and a midchannel 13 about twice the width of the narrow channels. The narrow channels face toward one and the midchannel faces away from one. At one side the sections have a looped flange 14 and the other side a plain flange 15. These can be hooked together as shown in Fig. 10. The hanger clips 16 are hooked over the girts, the deep recess 19 straddling the girt. These hanger .clips are so narrow that when the next section is put in place, the looped flange engages over the plain flange and also the hanger clips. The setup of the inside wall, section for section, then goes on until it has all been completed. The inside channel sections rest upon the floor or upon floor molding. The hangers do not support them on the girts, but simply tie them to the girts.

What I claim is:

1. A temporary metal wall structure comprising a plurality of channel sections of sheet metal, each with a plain flange on one edge and a doubled back flange on the other edge, said sections being hooked together with said plain flanges engaged within said double back flanges to form vertical ribs, a plurality of girts of thicker metal extending horizontally across and abutting said vertical ribs, a plurality of sheet metal clips supporting each of said girts, each of said clips including a pair of channel portions connected by a girt-embracing bridge portion and said channel portions of each clip being deep channels frictionally engaging a rib for temporary support.

2. A metal wall structure comprising a plurality of channel sections of sheet metal, each with a plain flange on one edge and a doubled back flange on the other edge, said sections being hooked together with said plain flanges engaged within said doubled back flanges to form vertical ribs, a plurality of girts of thicker metal extending horizontally across and abutting said vertical ribs, a plurality of sheet metal clips supporting each of said girts, each of said clips including a pair of channel portions connected by a girt-embracing bridge portion, said channel portions of each clip fitting on the same rib and being welded thereto.
