The truss includes three or more chord elements (two or more upper chord elements and one or more lower chord elements) and one or more web elements. Embodiments of methods according to the disclosure include estimating a first change in length for each of the two or more upper chord elements and estimating a second change in length of each of the one or more lower chord elements, the first change in length and the second change in conditions to which the truss is exposed. The method may also include selecting the one or more web elements from the plurality of wood members such that it compensates for deformation caused by the first change in length and the second change in length. | 09-12-2013 |

| 20080222989 | Metal Roof Truss Connection - A novel connection means between chord members and stiffening members of a metal roof truss. Each member includes internally pressed circular sections adapted to engage one another and thereby provide for a joint having greater shear strength than conventional joints. Each member includes two parallel side walls adapted to engage one another, this further strengthening the joint in that there are two connecting surfaces, and located between each engaged walls is a cylindrical ferrule adapted to prevent inward deflection of the walls when secured. | 09-18-2008 |
| 20100326003 | PORTABLE MODULAR ROOF TRUSS SYSTEM - The present invention provides a portable modular roof truss system for creating a symmetric roof. In one embodiment, the portable modular roof truss system comprises a collar, a crossbar, two arms, two connecting members, and a locking mechanism. The arms are elongated hollow cylinders coupled to opposing sides of the hollow cylindrical collar at a predetermined slope. The crossbar is also an elongated cylinder residing parallel to the ground and is coupled to both arms. Each hollow cylindrical connecting member is coupled to the end of an arm, respectively. Finally, the locking mechanism is coupled to the bottom portion of the collar and prevents a roof pole residing therein from moving back and forth. Each connecting member further comprises two apertures residing on opposite sides of the member used to couple the truss system to a variety of truss components (e.g., spacers, clamps, hinges, etc.). | 12-30-2010 |
| 20130118110 | PORTABLE MODULAR ROOF TRUSS SYSTEM - The present invention provides a portable modular roof truss system. In one embodiment, a portable modular roof truss system comprises at least one roof truss device comprising a roof apex collar, a crossbar, two arms, and two connecting members. The collar comprises two separate members coupled together by at least one bolt to form an opening capable of receiving a roof pole. In another embodiment, a portable modular roof truss system comprises two roof apex collars. In yet another embodiment, a roof truss device comprises a collar, a crossbar, two arms, and two connecting members. The collar comprises two separate members coupled together by a hinge to form an opening capable of receiving a roof pole. | 05-16-2013 |
| 052643000 | Structurally related trusses | 6 |
| 20090158686 | Truss Elements and Space Truss Diagonal Member Manufacturing Method - There is provided a truss element in which space truss diagonal members can be easily integrally formed by being drawn in a predetermined direction. This truss element is formed in a corrugated shape with mountain portions | 06-25-2009 |
| 20090293408 | Wooden roof truss - A roof truss is provided comprising a bottom chord, a first top chord, and a second top chord forming a triangle with an apex at a distance A above the bottom chord. At least a web member is disposed between the top chords and the bottom chord such that, in a first state of operation, the at least a web member is capable of transmitting at least one of a tension force and a compression force between the top chords and the bottom chord. The roof truss further comprises at least an expandable interface for expandable interfacing at least one of the at least a web member with one of the chords for enabling, in a second state of operation, expansion of the distance A to an extent that uplift of the bottom chord is substantially reduced. | 12-03-2009 |
| 20100180531 | Truss chord and truss system with ribs and radiuses - A truss chord includes a facing surface with ridges, sides with ridges, and an attachment surface on the side to attach to frame members. The truss chord transfers the weight to the frame member, and the truss chord helps prevent lateral movement relative to the frame member. The truss chord is made of extruded aluminum, and includes a flared section at the interface between the facing surface and the side that forms an arc, and a portion at the end of the side in the shape of an arc. A truss chord system includes top and bottom truss chords connected by square tubing frame members. | 07-22-2010 |
| 20140305066 | Corrugated Metal Plate and Overhead Structure Incorporating Same - A corrugated metal plate comprises a plate configured to define a series of crests and troughs, where the plate has longitudinal edges extending parallel to longitudinal axes of the crests and the troughs and transverse edges extending orthogonally to the longitudinal axes of the crests and the troughs. The corrugated metal plate further comprises at least one of: at least one longitudinal flange extending from each longitudinal edge, and at least one transverse flange extending from each transverse edge. | 10-16-2014 |
| 20140373481 | Lattice Girder Structure Using Innovative Multiple Joints For Roof Covering Purposes - Roof truss system comprising tie rods, struts, knee rafters, and innovative connection joints to cover buildings, especially suitable for being implemented by plastic materials. | 12-25-2014 |
| 20150075107 | BRACED TRUSS FRAME AND FALL PROTECTION SYSTEM - A bracing panel for constructing a truss frame having spaced trusses includes first and second engagement members having outer faces extending parallel to each other. A plurality of spacing members are attached to the first and second engagement members. The plurality of spacing members are configured and dimensioned to maintain the outer faces of the first and second engagement members parallel and spaced by a distance equal to a predetermined truss spacing. A bracing member extends between the first and second engagement members and laterally with respect to the spacing members for providing lateral support to the spacing members. | 03-19-2015 |
| 052644000 | Arcuate chord | 1 |
| 20150047287 | Modular Truss System - A modular truss system includes an upper chord and a lower chord. Each of the upper and lower chords has a pair of terminal ends and each of the upper and lower chords is arcuate between associated ones of the pair of terminal ends. A plurality of branches is removably attached to and extends between the upper and lower chords. Each of the branches has a first end and a second end comprising a saddle that receives one of the upper or lower chords at a fixed angle with respect to the upper and lower chords. The saddles ensure the branches are properly placed on the upper and lower chords. | 02-19-2015 |
