摘要

PROBLEM TO BE SOLVED: To provide a column-beam joining structure wherein cracks are not formed in a whole slab even when a big earthquake occurs.;SOLUTION: In the column-beam joining structure 1, a joint end part of a precast concrete beam 3 is placed on a beam supporting cog 5 of the precast concrete column 2, and a slab 4 formed by cast-in-place concrete is formed on an upper surface of the precast concrete beam 3. Transmitting main reinforcements 10, 11 transmitting the stress from an upper end main reinforcement 8 of the precast concrete beam 3 are arranged in the slab 4 along a side face of the precast concrete column 2, and a reinforcing bar 12 surrounding the precast concrete column 2 is arranged on the transmitting main reinforcements 10, 11.;COPYRIGHT: (C)2010,JPO&INPIT
