CONTINUOUS CONSTRUCTION METHOD FOR PRECAST CONCRETE COLUMN WALL MEMBER

摘要

PROBLEM TO BE SOLVED: To increase the efficiency and accuracy of execution by efficiently and continuously carrying precast concrete members into a prescribed position for the purpose of subsequently assembling the members. SOLUTION: In the continuous construction method for the precast concrete column wall member, column blocks 10 are carried into an earth retaining space 5 formed by ground excavation and longitudinally coupled together on foundation concrete 11, and column walls 3 composed of plural lines are constructed within the space 5. The column block 10 has an inverted T-shaped cross section with a base. Bearing balls 14 are spread for placement all over the top surface of a rail 13 wherein the base is laid on the foundation concrete 11 for the purpose of horizontally pulling the column blocks 10. The column blocks 10 are moved to a coupling position with the rolling motion of the bearing balls 14 and sequentially coupled together in the above position in order to construct the integrated column walls 3.
