CONSTITUTION: A vertical member has a passing hole at the center. A supporting plate(30) with many bolt holes and fastening holes is welded at both ends of the vertical member. Both ends of both sheet metal worked materials are folded outward. Both sheet metal worked materials are connected through a stiffening member in a horizontal member(40). A fastening member with a fastening pin hole in the vertical direction of a joining groove is attached to both ends of both sheet metal worked materials. Then, the horizontal member is installed through the supporting plate of the vertical member. Fastening pin holes are formed at both ends of a diagonal member(50). The diagonal member is installed through the hole for the diagonal member in the horizontal member.
