ABSTRACT:
A support member or tie bar for supporting and connecting T-shaped flooring members. The support member has an integral one-piece body with an elongated base and a number of support structures or bridges extending upwardly from the base. Each support structure has a relatively wide bottom and a narrow upper section. The upper section has a ledge formed on each transverse side thereof for supporting an edge of the horizontal portion of the T-shaped member. The base and the adjacent transverse sides of each pair of adjacent bottoms form a groove for receiving and supporting a bottom edge of the flooring member. Each support structure and the underlying base forms a trapezoid shape as seen in longitudinal cross-section and the center of the trapezoid is hollow. Each ledge is located a short distance below the top of the support structure. A transversely extending horizontal lip is formed on each transverse side of each support structure at the bottom of the support structure but spaced above the top surface of the base.
