  • Publication number: 20110016820
    Abstract: The present invention relates to a metal roof bracket and hip plate assembly used to connect up to three truss or support members with a metal roof truss. This novel means of connection, which may well utilize the co-pending application's novel connection method, provides a more efficient means of assembly than the traditional assembly techniques. The bracket allows the support member to be held by the hip plate while aligning the bracket into a position where it may be mounted thereto. It also allows for the support member to be rotated into a desired position before fixing.

  • Publication number: 20080222989
    Abstract: 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.
