HYBRID PRE-FABRICATION TRUSS GIRDER USING PRE-STRESS CONCRETE MEMBER AS TOP AND BOTTOM MEMBERS AND STEEL MEMBER AS VERTICAL AND DIAGONAL MEMBERS, WHEREIN GIRDER IS CAPABLE OF BEING USED AS A MAIN

摘要

PURPOSE: A hybrid pre-fabrication truss girder is provided to allow for ease and simplicity of manufacture and assembly, while achieving improved transport convenience by reducing weight of the girder. CONSTITUTION: A pre-cast is fabricated by using a pre-stress concrete, and applied to pre-stress tendons(7,8), to thereby obtain a top member(1) and a bottom member(2). A vertical member(3) and a diagonal member are produced from a steel member, and have ends with anchor steel plates welded thereto so as to connect the vertical member and the diagonal member to the top and bottom members. Each component is connected through a nut(6). The pre-stress concrete member is used as top and bottom members and the steel member is used as vertical and diagonal members.
