Coupling structure of columns and beams at the junction fittings and wooden buildings for wooden building

摘要

PROBLEM TO BE SOLVED: To provide a joint metal for a wooden building and a connection structure of a column and a beam in a wooden building, capable of preventing a pair of side plates from opening, and having strong resistance force against an earthquake or the like.;SOLUTION: Surfaces 20 to be pressure-welded of a pair of separation plates 19 are composed of inclined surfaces lowered as approaching the inner side, and each of angles θ formed by the pair of surfaces 20 to be pressure-welded and a pair of surfaces 24 to be joined which are both side faces of a support plate 15 is 70°. A pressure-welding surfaces 38 of a pair of insertion parts 37 are composed of inclined surfaces raised as approaching the inner side, and each of angles α formed by the pair of pressure-welding surfaces 38 and a pair of joint surfaces 36 is 70°. The insertion parts 37 are closely fitted to a connection groove 21, the pressure-welding surfaces 38 of the insertion parts 37 are abutted to the surfaces 20 to be pressure-welded of the connection groove 21, and the joint surfaces 36 of the insertion parts 37 are abutted to the surfaces 24 to be joined of the connection groove 21. When the pair of side plates 35 are to open, the pressure-welding surfaces 38 of the insertion parts 37 are pressure-welded to the surfaces 20 to be pressure-welded of the connection groove 21.;COPYRIGHT: (C)2012,JPO&INPIT
