Abstract
Abstract This specification discloses steel building components, such as hollow thin-wall studding and corrugated steel sheet, having novel means integrally formed therewith by which wall and floor surface elements such as plaster, cement and concrete, may be attached to the components. Several forms of attachment means are disclosed. One form comprises an anchoring loop formed by raising a narrow strip between two slits in the sheet steel forming the studding or corrugated steel sheet. Another form is a combination of the loop and a locking prong in line therewith, the loop serving to support a reinforcing element, such as metal lath, in spaced relation to the studding or to the corrugated steel sheet and the prong serving to lock the metal lath to the raised loop. Another form comprises an inverted T-shaped tab, struck from the metal sheet and bent normal thereto. The base of the tab serves to support metal lath in spaced relation to the steel studding or to the corrugated steel sheet and the end portion of the tab is bendable to lock the metal lath to the base of the tab. Rolling apparatus and a method for forming the steel studding and the various attachment means is also disclosed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
72 words
A building component comprising a corrugated steel sheet of the type forming a base for floor surface elements, steel sheet having integrally formed attachment means comprising a loop for supporting a floor surface reinforcing element in elevated position with respect to said corrugated steel sheet and a prong separate from and adjacent to the loop, said prong being bendable towards the loop to lock the floor surface reinforcing element on said loop.
Claim 2
Dependent Claim
72 words
A building component comprising a corrugated steel sheet of the type forming a base for floor surface elements, steel sheet having integrally formed attachment means comprising a loop for supporting a floor surface reinforcing element in elevated position with respect to said corrugated steel sheet and a prong separate from and adjacent to the loop, said prong being bendable towards the loop to lock the floor surface reinforcing element on said loop.
Claim 3
Dependent Claim
37 words
A building component according to claim 1, wherein said loop comprises a relatively narrow strip only the sides of which are severed from the steel sheet, said strip being raised into spaced relation to the steel sheet.
Claim 4
Dependent Claim
59 words
A building component according to claim 1, wherein said prong comprises a relatively narrow strip severed on both sides and one end from the steel sheet and extended to a position substantially normal to the steel sheet for installation of the floor surface element, and adapted to be bent subsequently to lock the surface element to the support loop.
Claim 5
Dependent Claim
106 words
A building component fabricated of sheet steel and comprising a steel studding of the hollow thin wall type, said studding having means integrally formed thereon by which wall surface elements are attached and supported in spaced relation thereon, said attaching means comprising loop means severed from the studding along two coextensive parallel lines and stretched laterally for supporting a wall element in parallel spaced relation to the studding wall, and flexible prong means partially severed from the studding wall separate from and adjacent to said loop means, which prong means is bendable toward the loop means to lock a wall surface element on said loop means.
Claim 6
Dependent Claim
106 words
A building component fabricated of sheet steel and comprising a steel studding of the hollow thin wall type, said studding having means integrally formed thereon by which wall surface elements are attached and supported in spaced relation thereon, said attaching means comprising loop means severed from the studding along two coextensive parallel lines and stretched laterally for supporting a wall element in parallel spaced relation to the studding wall, and flexible prong means partially severed from the studding wall separate from and adjacent to said loop means, which prong means is bendable toward the loop means to lock a wall surface element on said loop means.
Claim 7
Dependent Claim
52 words
A building component according to claim 4, wherein the said loop comprises a relatively narrow strip of the studding wall only the sides of which are cut from the studding wall and the portion intervening between the uncut ends of the strip being laterally deformed into spaced relation to the studding wall.
Claim 8
Dependent Claim
62 words
A building component according to claim 4, wherein said prong comprises a relatively narrow strip of the studding wall cut on the sides and on one end from the wall and extended to a position substantially normal to the studding wall for installation of the wall element and adapted to be bent subsequent theReto to lock the wall element to the studding.
Claim 9
Dependent Claim
42 words
A building component according to claim 4, wherein said prong is of a length and curvature such as to accommodate the thickness of the wall element when the prong is bent toward said loop to lock the wall element to the studding.
