  When the structural members 11 are vertically coupled to each other using the connecting jig 1, as shown in FIG. 3, the opening end 12 of the second structural member 11b is provided on the side wall of the first structural member 11a. The structural members 11a and 11b are assembled in the contact state. At this time, a through hole 16 is formed in the structural material 11b in a direction orthogonal to the axial direction, and the through hole 16 is formed by cutting the rib 13 vertically. Here, the connecting jig 1 is inserted into the through hole 16 and positioned so that the female screw portion 3 communicates with the cylindrical portion 15.

  On the other hand, a through hole 17 perpendicular to the axial direction of the first structural member 11a is formed in the first structural member 11a at a position facing the cylindrical portion 15 of the second structural member 11b. A screw (bolt) 18 is inserted into the through hole 17. The screw 18 inserted through the through hole 17 of the first structural member 11a is guided to the female screw portion 3 of the connecting jig 1 by the cylindrical portion 15 of the second structural member 11b, and is screwed into the female screw portion 3.
