Abstract: A backer clip, a plurality of which may be used to replace a second framing member normally employed for interior corner constructions of wallboard, ceiling and partition panel assemblies, and suitable for installation on a framing member, is of a continuous length of wire bent to shape so that an interior portion (or exterior portions) thereof is (are) substantially in a single plane, and the corresponding exterior portions (or interior portion) are (is) in a substantially parallel plane when the clip is installed on a framing member, with such interior and exterior portions being connected by legs in a plane at about right angles to such other planes when the clip is installed, and being of such length that sides of the interior and exterior portions facing each other can bear against faces of a substantially rectangular longitudinal framing member onto which the clip may be installed, with the legs along a connecting side of the framing member and with a part of the interior portion or exterior portions of

Abstract: An outside longitudinal corner construction of wallboard panels includes a framing member of the rectangular wooden stud or C-shaped sheet metal channel type, an edging member which is essentially T-shaped in cross-section or of a modified shape and a pair of wallboard panels fitted to the edging member and held to the framing member in such a way that a flap of covering fabric or sheet, as of a prefinished wallboard panel, or a part of the cover paper of such a panel, which cover material had the wallboard core and back removed from it, is wrapped around the edging member T cross-bar and held in position by the other wallboard panel. Thus, the edging member is concealed by the cover material, which is wrapped around it, and the corner construction matches in appearance the rest of the wallboard, with only one discontinuity along the length of the corner on one side thereof, and such is not conspicuous.

Abstract: Readily separable positively locking panel fasteners are described which are useful for holding panels together at sides thereof and to framing members; such as wooden or metal studs, to make walls, partitions or other structures incorporating side-abutting panels, such as wallboard panels. Mounting means for holding the panels together and to the framing member include engageable pairs of different panel fasteners, with one in each such pair being adapted to be held to a wallboard panel at a side thereof and to be fastened to a framing member, which fastener comprises a catch member, and to the other fastener of such pair being adapted to be held to another wallboard panel, which is to be installed in side-abutting or similar relationship to the other panel by means of fasteners which comprise a latch member which is engageable with the catch member of the other type of fastener.

Abstract: Walls and partitions are constructed by securing wallboard panels to a substructure, such as one of conventional metal or other framing members, by a series of concealed fastening clips, some of which are affixed to the framing members by nail or screw fasteners and others of which, while not held to the framing members, help hold adjacent wallboard panels together and in alignment with each other at the panel sides, which are usually in abutting relationship. The fastening clips are made from sheet or strip material and include a base portion having a substructure contacting surface and a panel contacting surface spaced apart by intermediate strengthening walls, a web portion at about a right angle to the base portion and tab means extending from the web portion and suitable for entering the side of the panel to which the clip is to be appended.

Abstract: Walls and partitions are constructed by securing of wallboard panels to a substructure, such as common wood or metal framing members, by a series of concealed clips of described construction, affixed to the framing members by nail or screw type fasteners. When the wall or partition is erected the fasteners are hidden from view so that joint treatment of the wallboard panels may be reduced or eliminated, depending on the type of wall structure constructed. The side or edge gripping clips are impaled along each side of abutting panels. When erected, a first series of clip fasteners are impaled on a side of a first wallboard and fastened to a framing member and a second series of such fasteners are impaled on an abutting or nearly abutting side of a second, wallboard panel, offset from the first series of clips so as to fit behind and be held by the first panel in a "tongue and groove" type cooperation.

Abstract: Mechanically held fasteners or clips invisibly secure common end-abutting wallboard panels to common wood or metal framing members. The fasteners are spaced apart, extending from the backs of wallboard panels and beyond their vertical ends so as to be conveniently screw fastened to a framing member. When screw fastened to common wall framing members, the clips, due to their spacing structure, which also improves clip strength, secure the wallboard panels slightly off the framing member front surface to permit offset fasteners of abutting wallboard panels to slide between the fastened wallboard panels and the framing members and to be engaged by the fastened wallboard panels in a "tongue and groove" relationship, preventing transverse panel movement.

Abstract: A fastener for use with other such fasteners in concealably holding wallboard panels to framing members and in abutting linear relationship with each other is made of sheet metal and includes a first part suitable for fastening to and against a framing member, a second part overlying a part of said first part and farther from the framing member than the first part, when installed, an intermediate section connecting said first and second parts so they can move relatively, with the intermediate section resisting such movement, a web extending from said second part and at the web end, an impaling part for insertion into a wallboard.

Abstract: Mechanically fastened appended tabs invisibly secure common edge-abutting wallboard panels to common wood or metal framing members. The fastener appendants are spaced apart tabs extending from the back of and exposed beyond the vertical edges of the wallboard panels so as to be conveniently screw fastened. When screw fastened to common wall framing members, the appended tabs secure the wallboard panels slightly off the framing member front surface to permit offset appendant tabs of abutting wallboard panels to slide between the fastened wallboard panels and the framing members and be engaged by the fastened wallboard panels in a tongue and groove relationship.

Abstract: The present invention relates to a system for the demountable attachment of architectural components and particularly the demountable attachment of wallboard panels to conventional wall and partition framing members, in such a way as to permit individual panels to be removed for access to the wall cavity. A preferred form of the invention utilizes a series of barbed clips, mechanically fastened to conventional framing members along each panel intersection joint. The clips are provided with a series of resilient barbs, protruding in angular opposing directions so as to penetrate and engage opposing marginal edges of abutting wallboard panels. The clip barbs spear wallboard panel edges in a pawl-like manner to permit the wallboard panels to be urged inward to the framing member surface, there retained by the natural outward obstruction of the hinged barbs.

Abstract: Building columns of generally squared C shape are strengthened by rigidification with a novel bridge member so that inward deflections of the flanges of the C are prevented by insertion of the bridge. The bridge includes a transverse intermediate portion which fits between the ends of the channel flanges to prevent inward deflections thereof, a pair of inclined crossing leg portions and a pair of opposing foot portions, each joined to a leg portion and adapted to fit in the interiors of opposed corners of the channel between the flanges thereof and the connecting part.

Abstract: Two abutting predecorated gypsum wallboards, being adhesively affixed to preformed sheet metal framing members, such as studs, are temporarily held firmly against a stud, which is disposed behind the joint between the two boards, by means including an elongate flat block disposed against the face of the board edges, a tie wire and a small arcuate wire guide, with the tie wire extending from one end, near the outer face of the block, to between the wallboard edges, through one hole in the stud, around the arcuate guide, back through another hole in the stud, out between the wallboard edges to the other end, also near the outer face of the block. The two wire ends are arranged to urge the block tightly against wallboard, when the two wire ends are twisted together. Removal of the wire and block involves cutting one leg of the wire, adjacent the block, and then pulling the wire out of the wall by pulling on the other wire leg.
