Abstract
A cross-brace for connection to a pair of parallel conventional joists comprises elongate brace members assembled to form a X-shaped array, with a pair of vertical reinforcement members extending between outer ends of the brace members. The brace members and reinforcement members are connected to one another and, when the cross-brace is assembled with the joists, the reinforcement members abut mutually opposed sides of the joists. When I-beams are employed, the outer ends of the brace members and the opposite ends of the reinforcement members cooperate to form right-angled notches for snugly receiving longitudinal beam members, which are interconnected in pairs by web members against which the reinforcement members abut. The web members are connected by dovetail joints to the beam members instead of simply being inserted in a conventional manner into slots in the beam members.
