Benefits of technology

[0013]The invention further seeks to provide a steel member as described including depressions formed in said web at spaced intervals indented from said outside to said inside surfaces and, openings formed in said depressions to reduce heat transfer.

Problems solved by technology

Wood is a relatively poor heat transfer medium.
Metal studs having solid webs however, do create a heat loss transfer path through the exterior wall or other structure.
This results in cold patches along the lines of the studs.
However this did not overcome the heat transfer problem.

Embodiment Construction

[0042]As already described the invention provides sheet metal studs, suitable for use in erecting various structures, walls, floors, roofs, and the like and also internal partition walls. The invention also provides sheet metal studs suitable for use in reinforcement of thin-shell concrete panels which are widely used in completing walls, in particular. Such thin-shell structures can also form floors, roofs and the like. The invention also provides a method of making such studs.

[0043]Referring to FIG. 1 it will be seen that the invention is there illustrated in the form 10 of a stud (10), formed of sheet metal, in this case steel. The stud (10) has a web (12) which is essentially planar, and edge flanges (14) and (16) along each side edge of the web (12). Each of the flanges (14) (16) is formed by bending side edges of the web (12) at right angles. Lips (18) are formed on each edge flange (14-16) again at right angles.

[0044]The flanges, and the web define a generally C-shape in sect...

Abstract

A steel stud member for use in supporting structures and having reduced thickness as compared with conventional studs, and having a web having side edges, flanges on the side edges, formed at angles to the web, the web and the flanges enclosing inside surfaces, and having outside surfaces for mounting structure, and plurality of narrow indented longitudinal ribs formed in the flanges, and in the web, indented inwardly from the outside to the inside of the flanges, providing greater load bearing capacity for a given gauge of steel. Also disclosed is a method of making such a steel member.

Description

FIELD OF THE INVENTION[0001]The invention relates to steel studs or structural members formed with edge formations and lengthwise indented ribs. In a particular preferred form the studs are formed with openings and edge formations along at least one side of the openings formed with at least two bends at respective first and second angles with respect to the plane of the stud.BACKGROUND OF THE INVENTION[0002]Steel studs of a wide variety have been proposed for erecting structures. Usually such studs are used to replace wooden studs. Wood is a relatively poor heat transfer medium. Heat loss through wooden studs has not been a significant problem in the past. Metal studs having solid webs however, do create a heat loss transfer path through the exterior wall or other structure. This results in cold patches along the lines of the studs. Condensation, known as “ghosting” appears along these lines.[0003]Such studs usually were formed as a C-section, i.e. there was a central web, and the o...
