ABSTRACT:
A bracket apparatus for attachment of a structural support, such as a truss, receives a pin in the form of a bolt which extends laterally through side edges of chord members of the support and a hole in a web member. The bracket apparatus includes two cooperating bracket members each including an upper plate portion, an internal tab portion, and external flange portion which extends in the same direction as the tab portion generally perpendicular from the upper plate portion. The tab portion and flange portion include holes which receive the pin extending laterally through the chord member. The bracket apparatus provides additional support to the pin in providing additional bearing surfaces in the form of the inner surface of the holes in the tab portion and external portion and thus reduces the amount of pin bending. Accordingly, lower grade steel can be used in the pin or a higher reaction load can be carried by the truss for a given pin.
