WWZ A'i'TORNEY 20 direct attachment of Patented Mar. 30, 1937 PATENT OFFICE STUD OR JOIS'I' Michael G. Vass, Maywood, Ill., assignor to United States Gypsum Company, Chicago, 111., a corporation of Illinois Application August 9,

3 Claims.

This invention relates to building constructions, and has reference more particularly to studs or joists together with their manner of utilization in a building construction.

In the construction of studs, joists and like building members, it is desirable that the memher be designed to provide the maximum of rigidity and strength when subjected to a given load. It is also desirable that these results be obtained with the least possible weight of metal to reduce the cost of manufacture. Building members of the class described should provide means for direct attachment of composition building boards thereto.

An object of this invention therefore, is to provide low cost building members of high rigidity and strength.

Another object of the invention is to provide metallic building members having means for the composition building boards; also to improve building members and constructions inother respects hereinafter specifled and claimed.

Reference is to be had to the accompanying drawing forming a part of this specification, in

which Fig. l is a perspective view of my improved building member,

Fig. 2 is an end elevation of the building memher, and

Fig. 3 is a sectional elevation of a building structure utilizing-the building members.

Referring to the drawing by numerals, the building members may be in the form of studs I I0, joists II or other desired beam or elongated truss, the distinction between the various members ordinarily being the depth of the member between outer webs l2 of spaced channels having inwardly extending flanges l3. In order to connect the channels H) in spaced relation, continuous bars M are bent into zi'g-zag form in such amanner that certain bar sections iii are attached at the bend point or fold I6 to flanges l3 lying on 5' the same side of channels It, while, the adjoining bar sections I! extend diagonally betweenthe vchannels ill at an inclination to the plane of said channels In, being attached at the fold line to the opposite flange l3. Due to the alternating diagonal bracing action of the bar sections H, as

clearly seen in Fig. 2,the stud or joist has unusual- 1y high strength and rigidity in spite of the fact that the structure is-inexpensively made throughout of comparatively lightweight metal. At the folds l6; thebars i5 and H may be attached to 1935, Serial No. 35,420

the inside of the flanges l3 by spot welding or 4 riveting, preferably the former. Joists M are constructed in the same manner as hereinabove described except that the distance between webs i2 is greater and a heavier metal is used throughout. The bars 15 and It may be square, rectangular orround in cross-section, or may have any other desired shape such as angles, channels, etc.

In constructing a building through the use of my improved building members, the flanges H3 at the top of the studs are cut back and web i2 is bent at right angles to form a flange is which is secured by a bolt or rivet 20 to the web I2 of the lower joist channel. In order to directly attach building sheets or boards 2! to the webs H of the studs l0 and joists H, I provide a multiplicity of perforations 22 in the webs i2, these perforations being arranged in a' series of spaced groups. Holes are punched through the boards 2! by pushing a sharp pointed punch through said boards, the point of the punch finding one of the closely spaced holes 22. Wood or drive screws 23 are inserted in the punched holes after the punch is withdrawn and engage in the registering perforations to draw the board'tightly against the channel webs l2. The boards 2| are attached to studs II] to form partitions, and to joists Ii to form ceilings and floors. These boards 2| may be composition boards or sheets of the types well known to the art, such as gypsum board, insulation boards, hard pressed boards, asbestos boards, plywood or sheet metal. The resulting building construction may be entirely fireproof if fireproof boards are used, and the building framework is light, inexpensive and is easily erected.

I would state in conclusion that, whilethe illustrated example constitutes a practical embodiment of my invention, I do not wish to limit myself precisely to these details, since manifestly the same may be considerably varied without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:-

1. A building member comprising a pair of elongated flat strips in spaced, parallel relation, and zig-zag bar sections connecting said strips, alternate bar sections extending from one edge of one strip to the diagonally opposite edge of the other strip and the remaining bar sections extending between adjacent edges of said strips.

'2. A building member comprising a pair of channel strips in spaced, parallel relation, said 10 strips having inwardly turned flanges and a web connecting said flanges, and zig-zag bar sections secured to said flanges and connecting said channels, certain of said bar sections extending at an inclination to the plane of said'channels and the remaining bar sections being substantially parallel to the plane of said channels, the webs of said channels being provided with a series of closely spaced perforations for receiving board attaching screws.
