METALLIC mamas Filed Dec. 14, 1958 lmwizfwt' E0 BTU m Ml.

Patented May 9, 1939 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to metallic girders in the form of H and I-beams and the like, and particularly to those which are built-up from rolled plate or sheets.

The art of metallic girders of the class described (commonly called metal lumber) has been considerably active due to the possibilities inherent therein. Such devices, if sufllciently strong, should possess great utility as a result of their low cost and light weight. However, many devices directed toward these ends fail in practicability due to. complexity, of design.

It is among the objects of the present invention to provide a strong and light weight metallic girder which is of relatively simple design and therefore one which is inexpensive to manufacture.

The foregoing and other objects will be apparent after referring to the drawing, in which:

Figure 1 is a perspective of the metallic girder of the invention.

Figure 2 is a view similar to Figure 1 but disclosing a modification.

Figure 3 is a perspective of another modification.

Referring more particularly to the drawing, the numeral 2 designates the flange member of the metallic girder of the invention. This flange member 2 is made from suitable rolled plate or sheet and has edge portions 3 which extend from the major plane thereof at acute angles.

The web member 5 of the girder is made from material similar to that of the flange member 2 and is disposed with its major plane at an angle thereto which is substantially normal (or 90 degrees). This web 'member 5 has its adjacent edge deformed to provide angularly extending tongues 6 which contact the inner surfaces 4 of the angularly extending edge portions 3 of the flange member 2. These tongues 6 extend alternately from opposite sides of the web member 5.

Referring to Figure 2 of the drawing, there is tending edge portions 3 of the flange member 2.

Preferably, the tongues 6 of the web 5 are welded to the angularly extending edge portions 3 of the flange member 2 at all contacting points. This is also the case with respect to the mid-por- 5 tion of the flange member 2 and the longitudinally spaced edges of the intermediate undeformed portions ill of theweb member 5 in the modification of Figure 2. These welds are shown at X. Under some conditions, however, (for example, in case of a continuously imposed vertical load) welding is unnecessary.

While I have shown and described several specific embodiments of my invention, it will be understood that I do not wish to be limited exactly thereto, sincevarious modifications may be made without departing from the scope of my invention, as defined in the following claims.

I claim: 7

1. A metallic girder comprising a flange member having angularly extending edge portions, and a web member having its major plane at an angle which is substantially normal to the major plane of said flange member, said web member having angularly extending tongues which con- 25 tact the inner surfaces of the angularly extending edge portions of said flange member.

2. A metallic girder comprising a flange memher having angularly extending edge portions, and a web member having its major plane at an angle which is substantially normal to the major plane of said flange member, saidweb member having angularly extending tongues which contact the inner surfaces of the angularly extending edge portions of said flange member, said tongues extending alternately from opposite sides of said web member.

3. A metallic girder comprising a flange member having angularly extending edge portions, and a web member having its major plane at an 40 angle which is substantially normal to the major plane of said flange member, said Web member having tongues which extend angularly toward the angularly extending edge portions of said flange member, said tongues having angularly extending edge portions which are parallel to and contact the inner surfaces of the angularly extending edge portions of said flange member.

4. A metallic girder comprising a flange member having angularly extending edge portions, and a web member having its major plane at an angle which is substantially normal to the major plane of said flange member, said web member having tongues which extend angularly toward the angularly extending edge portions of said flange member. said tongues extending alternately from opposite sides of said web member and having angular-1y extending edge portions which are parallel to and contact the inner surfaces of the angularly extending edge portions ct said flange member.

5. A metallic girder comprising a flange memher having angularly extending edge portions, and a web member having its major plane at an angle which is substantially normal to the major plane of said flange member, said web member having longitudinally spaced portions of its adjacent edge in contact with said flange member and intermediate angularly extending tongues which contact the inner surtaces oi the angularly extending edge portions oi said flange member.

1. A metallic girder comprising a flange member having angularly extending edge portions, and a web member having its major plane at an angle which is substantially normal to the major plane of said flange member, said web member having longitudinally spaced portions of its adjacent edge in contact with said flange member and intermediate angularly extending tongues, said tongues having angularly extending edge portions which are parallel to and contact the inner surfaces of the-angularly extending edge portions 01' said flange member.

8. A metallic girder comprising a flange member having angularly extending edge portions, and a web member having its major plane at an angle which is substantially normal to the major plane of said flange member, said web member ROBERT U. GEIB, JR.
