A plank and flange plate structure for providing additional bearing for the precast concrete planks on an underlying steel beam, the additional bearing being located on each side of the existing steel beam so as also to provide a transfer of the dead and live loads to the existing steel beam. Several embodiments include a square structure, made up of a pair of flange plates which rest on the steel beam, and a pair of plank plates supporting the precast concrete plank(s), and several structures located between adjacent steel beams, with two or three plank plates. Plank and flange plates may be secured together by welding, nut and bolt fasteners, riveting, or the parts may be formed (e.g., cast, molded, etc.) as a unitary structure.
