摘要

PROBLEM TO BE SOLVED: To provide a joint metal fitting for a wooden building and a connection structure of a column and a beam in the wooden building, for easily inserting an insertion part to a connection groove even when positions of the insertion part and the connection groove are somewhat shifted.;SOLUTION: A width dimension of the connection groove 21 is gradually reduced from an upper part to a lower part, and the width dimension of the insertion part 41 is also gradually reduced from the upper part to the lower part corresponding to a shape of the connection groove 21. The width dimension of an upper end part of the connection groove 21 is larger than a lower end part of the insertion part 41, and in a state of inserting the lower end part of the insertion part 41 to the upper end part of the connection groove 21, a gap is formed between a side face of the insertion part 41 and the side face of the connection groove 21. In the state of completely inserting the insertion part 41 to the connection groove 21, the insertion part 41 is firmly fitted to the connection groove 21 without play.;COPYRIGHT: (C)2012,JPO&INPIT
