It is characterized in that a mounting bracket provided is mounted on the pillar.

According to a second aspect of the present invention, the mounting member is a section steel having a U-shaped cross section, and the bolt insertion hole and the rivet insertion hole are provided in a web portion connecting a pair of flange portions of the section steel. It is characterized by that.

[0010]

According to the present invention, there is provided a bolt insertion hole for inserting a bolt for fixing the stud and a rivet insertion hole for inserting a rivet for fixing the outer wall panel on the stud. Since the mounting bracket is attached to the pillar, if the rivet is inserted into the rivet insertion hole while the bolt is inserted in the bolt insertion hole, the stud will be supported by the bolt and the rivet, and the bolt will be the center of rotation. The rotation of the studs is blocked.

According to the second aspect of the present invention, the mounting member is a section steel having a U-shaped cross section, and the bolt insertion hole and the rivet insertion section are formed in a web portion connecting a pair of flange portions of the section steel. Since the holes are provided, the rigidity in the horizontal direction and the vertical direction in the mounting portion is enhanced.
