  • Patent number: 5732918
    Abstract: A roof catchboard bracket for securing a catchboard to a roof, preferably formed from a plastic material. The device includes an L-shaped bracket having a first leg adapted to be removably secured to a roof and a second leg adapted to be removably secured to a catchboard. An integrally formed brace portion extends intermediate the first and second legs for bracing the second leg against the first leg. Other features include a provision for nesting a plurality of such brackets one on top of the other, and pry chamfers which allow the brackets to be readily removed after nailing to a roof surface.

  • Patent number: 4630424
    Abstract: At each end of a top hung wood truss one or more end webs are attached to top chord by connector plates which not only embed in the end webs and the top chord in the region of the joint between them, but also extend outwardly beyond the joint in the form of legs that embed within the chord extension, that is the portion of the top chord which extends beyond the joint and rests on the bearing surface that supports the truss. Indeed, the outwardly projecting leg of each connector plate is located over the bearing surface, its lower margin being close to the underface of the chord extension to lessen the tendency of wood fibers in the top chord to crush in that region. The plate strengthens the top chord at its extension, enabling it to better withstand the shear forces and moments that are within the chord extension.
