UNITED STATES WELDED STRUCTURAL MEMBER Gerald G. Greulich, Mount Lebanon, Pa.

Application December 31, 1936, Serial No. 118,663

1 Claim.

This invention relates to the production of welded structures by means of a suitable web and a. flange welded thereto.

Other objects and advantages will become apparent as the description proceeds, in which:

Figure 1 is a perspective view of the assembled structure;

Figure 2 is a detailed transverse sectional view showing the iiange and web before welding;

Figure 3 is a detailed sectional view showing the ange and web after welding; and

Figure 4 is a detailed section of the web edge.

In the drawing, the numeral 2 designates the web, which is of single thickness of metal. The

Vweb may be aplain straight sheet of metal or,

if desired, may be provided with a plurality of projections 3 and 4,. of any desired shape, extending alternately from each side of said web, as shown in Figure 4.

The ange comprises a single piece of metal bent or folded to provide an outer body-portion 5 and an inner body-portion 6. lllhe inner bodyportion ii is spaced from the outer body-portion 5, as shown in Figures 2 and 3, and is provided with laterally extended portions il.

The Web 2 is adapted to be positioned between the laterally extended portions l and extend beyond the inner body-portion 6 and contact with the inner face t of the outer body-portion it. When in such position, the web and laterally extended portions are spot welded, or if the web be of a plain straight sheet material, the web and laterally extended. portions are spot welded at various points along the entire body.

While I prefer that the thickness of the metal in the ange be less than the thickness of the metal in the web E, if desired, the total thickness of the folded flange may .be equal to or greater,

.than the thickness of the web. As an example of the ratio of thickness between the single thickness o metal in the harige and the web, i propose that this single thickness of the ma teriel from which the iange is formed should range between '10 and 95 per cent. of the thickness of the web metal or the combined total thickness of the doubled-up flange should range from 140 to 190 per cent. of the total web thickness. By such a differential in the web and iiange thicknesses, it is possible to obtain unlimited combination of web and flange sizes which permits production of any depth, width.

and height of beam desired.

Also, it is desired that the web 2 contact the inner face of the outer portion of the ange and, in so doing, reduce the amount of welding required and at the same time produce a beam structure having suitable advantages over the beams of the present construction.

The principle involved herein may be applied with web members and flange members of other shapes. It also may be applied to other structural members having a web and a iiange or flanges Welded` thereto, such as, for example, Ts and other common types.

While I have shown and described a specific embodiment of the invention, it is to be understood that I do not wish to be limited exactly thereto, since various modifications may be made Without departing from the scope of the invention, as defined in the following claim.

l claim:

A structural member comprising at least one flange formed from a singie piece of metal bent back upon itself to provide a double thickness of metal in spaced relationship and including laterally extended portions from the inner portion of said ange and a web provided with a plurality of projections extending alternately from each side thereoi positioned between said laterally extended portions and welded thereto at the points said projections contact said laterally extended Bange portions, said web adapted to project beyond the inner portion of said ange to contact the inner face of the outer portion thereof.
