PRECAST CONCRETE CONSTRUCTION SYSTEM USING GERBER'S BEAM

摘要

The present invention relates to a precast concrete (PC) structure bonding system using a gerbers beam, wherein first and second separate PC girders having a gerbers beam structure are selectively joined to a column member, wherein the first PC member and the column member are anchored by joining a main bar to an open type through-hole or a sleeve to significantly reduce production cost and a construction period when compared with an existing system. In addition to this, a corresponding second PC girder is joined to a point on each of the first and second separate PC girders, wherein the point has minimum bending moment and shearing force to stabilize the joint structure and reduce the cross-sectional area, thereby lowering production cost and significantly improving workability and productivity. Furthermore, according to an alternative embodiment of the present invention, a mountain girder (MGS) or a double girder (MGS) can be applied to the first and second PC girders having a gerbers beam structure.
