Abstract:
A metal truss system comprising a pair of chord members of generally U-shaped cross-sectional configuration is joined together by a web formed of a single continuous piece having a wave shape. The apexes of the web are adapted to be received in each chord. The legs of the chords have inwardly recessed portions to form a narrowed throat portion, which provides a stop against which the apex of the web abuts. The resulting positioning of the web apex presents a maximum surface area for welding the web to the chord member. This enables an optimum amount of welding, while minimizing the weakening of the metal being welded. The configuration of the chords and web permits rapid fabrication of the truss.
Abstract:
The present invention relates to a method of manufacturing a self supporting system capable of forming a substructure of a building and also a joint system utilized to form such a substructure. This joint system includes at least two lengths of sheet material where one end of each length of sheet material is pre-cut at a predetermined angle. The angle of the pre-cut ends are configured to receive each other to join the sheet material lengths together without the requirement of a bracket to provide a self supporting system capable of forming a substructure of the building.
Abstract:
Embodiments of truss systems and methods are disclosed. One system embodiment comprises a first chord, a second chord, and a continuous web member connected to the first chord and the second chord.
Abstract:
The present invention provides for an improved method of fabricating trusses. The improved trusses are made from elongated, tubular members forming the chords and/or webs. A metal connector plate is used to connect the chords and webs to form the truss. Further, modifications of the connector plates are used to facilitate the connection of trusses into truss assemblies. Additionally, other modifications of the connector plates are used to facilitate the connection of the trusses to the supporting structure.
Abstract:
A truss (10) for a roof having an attic space or the like, the truss including: a substantially vertical web (15, 16) adapted to constitute a stud for supporting the attic wall; a substantially horizontal web (14) adapted to constitute a support for the attic ceiling or ceiling battens, and a bottom chord (11) adapted to constitute a bearer or joist for the attic floor.
Abstract:
A system for building steel framed structures (9,12) wherein a series of slots (2) and tongues (1) are punched in the various components that are required to make a wall (9) or truss (12), the slots (2) to position components precisely and the tongues (1) to secure them. The frames (9) or open web trusses (12) are thus able to be fabricated without the necessity of a jig or additional fastenings, allowing the fabrication to be carried out quickly and on site if desired. Also disclosed is a tongue (3) which is slit to it's base enabling the halves of the tongue to be bent in opposite directions and a securing bracket (Fig.8) for the system.
Abstract:
For a truss, a hinge assembly for connecting truss members that form the truss. The hinge assembly may includes a first hinge plate having a first boss formed thereon and a second hinge plate having a second boss formed thereon. The second boss defines an opening for pivotal receipt of the first boss. The hinge assembly also includes a retainer for maintaining the pivotal receipt of the first boss in the second boss. When the first hinge plate is attached to a first portion of a truss and a second hinge plate is attached to a second portion of a truss, the first and a second truss portion can be pivoted relative to each other to enable portions of the truss to be collapsed for transporting purposes.
Abstract:
A truss system wherein the structural components and fixtures are formed from light gauge metal. The trusses are fabricated from roll formed truss chord members and truss web members. The truss chord members are roll formed to have a generally U-shaped cross-section (30) with a base (32) and two substantially parallel legs (34) with recessed web attachment faces and outwardly extending stiffening flanges (42) to improve structural capacity thus improving the strength-to-weight ratio of the chord member and minimizing costs. The truss web members are formed by nesting two roll formed C-shaped members (110) to form a web member which is box-shaped in cross section. The web members provide the structural advantages of a box-shaped member and the ease and flexibility of a roll formed member. The truss system and method provides improved means and methods for positioning and attaching the web members to the chord members as well as improved truss clips (90) for resistance to uplifting forces and improved truss jack clips for forming hip connections.
Abstract:
A roof truss of the kind having a bottom chord (13) and a pair of inclined top chords (11, 12), each of the chords having an approximate C channel cross sectional shape, wherein the top and bottom chords lie in a single vertical plane with the channels opening in the same direction. The bottom chord has openings formed in the top flange (20) of the channel at opposite ends and an upwardly projecting web extension (21) extending longitudinally to the bottom chord. Each of the top chords (11, 12) has at it's apex forming upper end cut to a shape so that their upper ends overlap with their webs in the region of the overlap being in face to face relation. The apex angle can be varied.
Abstract:
The present invention relates generally to structure layout and marking during construction. More particularly, the present invention relates to an automated layout system that acquires data directly from the architectural drawing, blueprint, or CAD (computer aided design). The automated layout system then generates a full banner for denoting the precise location of building elements such as studs, doors, windows, etc., for a structure under construction.
