Junction structure and bonding method of precast reinforced concrete beam members to each other

摘要

PROBLEM TO BE SOLVED: To provide a method and a structure for joining precast reinforced concrete beam members together, which can drastically simplify large-scale post-work without the horizontal displacement of PCa beam members when the PCa beam members are joined together, which realize the shortening of a construction period, and which are excellent in construction work characteristics and economic efficiency.;SOLUTION: Joint ends of the beam members 1 and 1 are provided with slit-like void portions 2 which correspond to each other when they are brought closer to each other almost up to an abutting state in advance, respectively. The beam members 1 and 1 are brought closer to each other up to the almost abutting state, and positioned in such a manner as to be arranged in an opposed state; a connecting member 3, which is composed of a reinforcing bar 3a etc. formed in an X-shape, is inserted into the void portions 2 corresponding to each other, and positioned in such a manner as to almost evenly straddle both the beam members 1 and 1; and after that, a hardening material 4 is infilled into the void portion 2, so that the precast reinforced concrete beam members 1 and 1 can be integrally joined together.;COPYRIGHT: (C)2008,JPO&INPIT
