Coupling structure and construction structure body

Abstract

A coupling structure in which two structure members (1, 2) are connected to each other. The structure members integrally have projecting parts (32, 42) projecting from one side part (A side or B side) thereof, respectively. The two structure members are close to each other, and the projecting parts overlap the side parts of the counterpart structure members (2, 1) so as to be positioned on sides opposite to each other, respectively. The projecting parts and the side parts of the counterpart structure members are each fixed by bolt joint. Thus, mainly, it is possible to provide a coupling in which the number of components used for connecting the structure members to each other is reduced, projection from (flange parts of) the structure members is eliminated, and construction is easily performed.
