JOINING METHOD FOR PRECAST CONCRETE ANTI-SEISMIC WALL AND CONCRETE MASS

摘要

PURPOSE:To facilitate construction and transportation of a precast concrete anti-seismic wall and accomplish a reliable joint with concrete mass by embed ding an insert inside of the joint end with the concrete mass of a precast anti- seismic wall, fitting a fixation anchor at the time of placing, and then pouring in the mass concrete. CONSTITUTION:Reinforcing rods are accommodated in a precast anti-seismic wall A, and an insert 1 fitted with an anchor rod 2 is embedded fast inside of the joint end with a pillar B. Then, this anti-seismic wall A is placed in the joining position with the pillar B. An anchor 6 for fixation of pillar is fixed to the insert 1, and pillar concrete is poured in, followed by construction of pillar B, which is consolidated with the anti-seismic wall A. This facilitates rod arranging and form removal at the time of fabricating precast anti-seismic wall A, also provides easy handling in stocking and transportation as well as easy erection of anti-seismic wall, and allows accomplishment of consolidated structure of the mass concrete and anti-seismic wall through anchoring.
