Method of building concrete structure using attachment plates adjoining ends of concrete beam with walls of abutments

摘要

The present invention relates to a technique for constructing a concrete structure by mounting a beam made of concrete such as a PSC beam or a composite beam on an alternating wall, and a beam attached with an attachment for improving the mutual confinement effect is mounted on the alternate wall It is easy to construct concrete structure by placing concrete on top of both alternate walls and bottom plate, and the fracture between wall and upper structure is sure. The attachment of the present invention is formed of a continuous plate having a stud bolt. A bolt hole is formed at one end of the pivot plate to be engaged with the beam side portion, and a through hole is formed at the other end. Since the alternating wall and beams are connected in the form of a fissure, the shape of the concrete structure is reduced, and the cost of construction is reduced as well as the maintenance of the structure is simplified. The step of constructing comprises attaching and fixing an attachment to the end of the beam by making an attachment; Constructing each of the alternating walls in such a manner that a support portion is provided at the upper end of the wall and a vertical reinforcing bar is projected; Placing the beam on a receiving portion and installing a horizontal reinforcing bar through the through hole; And placing the concrete on the top of the wall and the bottom plate to integrate the beam and the wall.
