Metal Roof Truss Connection |
摘要 |
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.
