CONCRETE SHEAR KEY STRENGTHENED WITH STEEL COVER PLATE AND TENSION MEMBER AND THE CONSTRUCTION METHOD THEREWITH

摘要

PURPOSE: A precast steel composite deck with a concrete shear key, strengthened with a steel plate, and a connection member and a construction method thereof are provided to enable cost-efficient construction by not requiring a welding work. CONSTITUTION: A precast steel composite deck(100) with a concrete shear key, strengthened with a steel plate, and a connection member comprises main tension beams(110), intermediate plates(120), upper bars(130), connection sleeves(140), upper concrete, and steel plates(160) for shear key reinforcement. The intermediate plates are used as a lower form of the upper concrete. The upper bars comprise horizontal and vertical bars(131,132). The connection sleeves are formed on the ends of the horizontal bars and have grouting holes(141). The upper concrete is placed on the top of the main tension beams. The steel plates for shear key reinforcement are installed concrete shear keys to be separated from the main tension beams and the sides of the upper bars.
