Beam-to-column main reinforcement destination pairs hollow precast concrete column unit and pillar construction method using this pillar unit

摘要

PROBLEM TO BE SOLVED: To provide a hollow PC column unit having high constructing efficiency with few craning times for every constructing floor and dispensed with assembling of a scaffold on every constructing floor. ;SOLUTION: A column beam main bar pre-assembled hollow PC column unit 11 is formed of hollow PC column forms 12 for N floors, beam main bar- assembled reinforcement baskets 13 for N floors placed horizontally on the hollow PC column forms 12, and an assembled column main bars 14 having the length for two floor heights of N floor-(N+1) floor inserted into the hollow PC column forms 12 through the panel zone part 21 of the beam main bar pre-assembled reinforcement basket 13. This column beam main bar pre- assembled hollow PC column unit 11 is assembled and stored in a stock yard. According to this, the lifting times for every constructing floor is minimized, and assembling of a scaffold every constructing floor is dispensed with, so that the construction efficiency is improved. Further, the stock yard can be used more effectively than in the separate storage of reinforcements such as column main bar or beam main bar and the hollow PC column forms 12.;COPYRIGHT: (C)1999,JPO
