Abstract: This disclosure relates to a composite structural member comprising a body part and multiple rigid strips which are attached to and separated by the body part. The body part is formed by a core having substantially flat parallel sides and opposed edges, and the opposed edges are covered by the rigid strips. As an example, the core is made of gypsum, and the strips are made of sheet metal. The rigid strips enable screw fasteners to be secured to the structural member. The sides of the core are preferably covered by side sheets.

Abstract: A hollow shaft wall corner with each of two walls having alternating horizontal studs and horizontally extending core boards, with the horizontal studs of the two respective walls adjoined at the wall corner by small clips affixed to the horizontal studs. A method of construction of the wall further includes small clips adjoining the ends of core boards at the wall corner.

Abstract: This disclosure relates to a reinforced metal stud for use in a hollow wall. The wall includes sheet metal studs placed horizontally between adjacent, horizontally extending gypsum core boards, typically in the walls surrounding an elevator shaft and stairwells, and in area separation walls and the like. The metal studs include an inner flange, an outer flange and an adjoining web connecting the flanges, with a core board abutting each side of the web. Standard or special fire-retardant gypsum wallboards are attached by fasteners to the outer flanges of the metal studs. A hollow space is thus formed between the core boards and the wallboards, the outer flange and a portion of the web being within the hollow space. A reinforcement channel is provided for attachment to and strengthening of the stud. The web and the outer flange of the stud form a partially enclosed space, and the reinforcement channel nests in the enclosed space.

Abstract: This disclosure relates to a wall construction including an outer panel and an inner panel, the inner panel being formed by at least one wallboard. The outer and inner panels are substantially parallel and are spaced apart to form an interior space between them. Within the interior space and secured to the outer and inner panels are one or more framing members made of roll formed sheet metal. Each framing member comprises a web which extends between and is substantially perpendicular to the outer and inner panels. At an outer portion of the member is formed an outer flange which abuts and is secured to the outer panel. At an inner portion of the framing member is formed at least one tab which extends closely adjacent the inner panel and at least one cutout formed in the member. An adhesive secures the inner portion including the tab to the inner panel. The framing member may further include a clip which extends through the cutout and is attached to the panel.

Abstract: A hollow shaft wall with horizontal studs having angled stud webs forming a channel with the stud inner flanges. Core boards are held by one edge in the angled channel and the other edge held by suitable means on an adjacent horizontal stud. Wallboards are spaced from the core boards and are secured to flanges of the studs. Supports are provided at the ends of the core boards and the studs for holding the wall in a vertical orientation.

Abstract: This disclosure relates to a riser comprising an elongated web having one or more folds which form at least one ridge and slopes extending away from the ridge. When in use as a riser, the web is positioned on edge so that the edge surfaces of the ridges and the slopes engage the bottommost article being supported. The web preferably includes strengthening elements located at at least the ridges. A group of risers are nestable whereby they may be compactly stacked for storage and/or shipping. The edge surfaces have a surface area sufficient to avoid forming a substantial imprint in the article. The risers may be made of a recycled material, such as wood chips, plastic and gypsum, and the risers are reusable.

Abstract: An elongated metal structural member including an expanded metal web formed by severing a metal strip along a sinuous path forming a plurality of keystone-shaped tabs on each half, moving the two halves directly away from each other until outer corners of the tabs of one half overlap outer corners of the tabs of the other half, and affixing together the outer corners of one half with outer corners of the other half.

Abstract: A hollow shaft wall stud corner clip adjoins ends of horizontal studs at a shaft wall structure corner and is readily adaptable for supporting core boards in a fire rated ceiling or a fire rated duct and for holding core board in place at a top or a bottom of a horizontal stud hollow shaft wall. The clip has a central web for positioning against a stud or track flange and an angled flange with a core board-supporting extremity.

Abstract: A laterally stiffened, elongate, roll-formed metal stud, or equivalent structural member having a central web with alternating deformed and undeformed portions.

Abstract: A generally flat attachment plate for providing a mounting surface on a side of a Z-stud, which surface is perpendicular to the Z-stud flanges. The plate has tongues on one edge engaging an inwardly directed lip on the Z-stud flange, and means on the opposite edge to affix the plate to the angled web of the Z-stud, such as by tabs which fit into slots on the web. The Z-stud has two rows of slots for use in mounting the plates or for suspending the Z-stud from a ceiling.

Abstract: A hollow shaft wall with horizontal studs held between corner posts and an intermediate vertical wall support post, which intermediate post has a central reinforcement channel, the reinforcement channel has a bottom and two side walls, the channel is filled with strips of gypsum board, and the two side walls have metal channels affixed thereto providing oppositely opening grooves for receiving and supporting the ends of said horizontal studs.

Abstract: An extendible stud, consisting of two substantially identical C-studs each of which has opposed flanges of substantially different widths and inwardly turned lips at the flange outer edges, and each C-stud having an elongate central area in its web located at substantially the middle of said C-stud cross-section, which two C-studs are interconnected by the narrow flange of each being held within the channel formed by the wider flange and the associated lip and web of the other C-stud, and the elongate central areas of the webs of the two C-studs abutting one another.

Abstract: A foldable floor track or ceiling track having 1/8-inch-wide slots in the flanges and a 1/8-inch-high rib in the web, between the slots, permitting the track to be cleanly folded in half at the factory, for convenient packaging and handling, and then unfolded and fastened to the floor and the ceiling at a job site.

Abstract: A wallboard package having edge protective tape which connects two wallboards face-to-face, with an adhesive film on the tape inner surface adapted for use in affixing the wallboards to wall studs.

Abstract: A hollow shaft wall having a cavity of a first width substantially throughout said wall and a cavity of a greater width in a limited section for the reception of a relatively deep utility box, the limited section having board omitted on one side thereof, and a short section of board affixed over the omitted section, creating the cavity of a greater width. The short section of board is affixed to boards or studs of the wall by short elongate clips having a pair of channels opening in opposite directions.

Abstract: Horizontal panels, each consisting of top and bottom horizontal studs, with gypsum boards affixed therebetween, are stacked vertically, with suitable means for maintaining the wall vertical.
