Abstract: A web stiffener for use with a building component having a web portion and a leg portion that extends generally outwardly from the web portion, the leg portion having a lip that extends generally upwardly therefrom. The web stiffener includes a first member and a second member extending generally outwardly from the first member, wherein the second member defines a slot to receive the lip of the building component. An assembly that utilizes the web stiffener and method of attaching the first building component and a second building component utilizing the web stiffener are also disclosed.
Abstract: A joist support system and apparatus. The system may include a joist rim that has at least one attachment tab integrally formed therein to facilitate attachment of a joist to the joist rim. Reinforcing ribs are preferably provided adjacent the attachment tabs for providing desired structural integrity to the attachment tab connection. The system may also include a C-shaped joist that has a plurality of oval-shaped openings therein to enable components such as ducts, wires, piping, etc. to pass therethrough. The joists may also be provided with a plurality of mounting holes that are adapted to accommodate wire retainer members for supporting insulation between respective joists. The system may also include preformed blocking members that are sized to extend between adjacent joists and be attached thereto to provide lateral support to the joists.

Abstract: A truss pitch break connector plate having a main body portion. A first stiffener flange projects generally perpendicular from one face of said main body portion along an arcuate first edge having an outer radius. A second stiffener flange projects generally perpendicular from the opposite face of the main body portion along a arcuate second edge having inner radius. The main body portion preferably is generally sector-shaped but alternatively it may be circular. The overall arrangement is such that the pitch break connector plate will accommodate top chords of different sizes; and is capable of maintaining the top chords at any one of a range of roof pitches.
Abstract: Cold formed, light-gauge metal structural framing for building construction, including a one-piece jamb member, a one-piece load-bearing header member connected to said jamb member, and a one-piece upper channel member connected to at least one of said jamb member and said header member and spanning a juncture of said jamb and header members. The framing may also include an expandable, cold formed, light-gauge metal window frame subassembly.
