Claims (1)

[Scope of Claim for Utility Model Registration] (1) A channel-shaped abdominal member made of an extruded section with non-return claws formed on the inner edges of both sides of the opening, and latching pieces that engage with the non-return claws of the abdominal member on the edges of both openings. Assembling a hollow crosspiece with a channel-shaped back member made of an extruded member having an inwardly inclined introduction slope portion which can be pushed inwardly between the two non-return claws at the tips of both the locking pieces, A round bending structure of a hollow crosspiece, characterized in that the abdominal member and the back member are bent relative to the abutting surfaces by mutually shifting the abutting surfaces. (2) A practical method in which a notch is provided on each side of the abdomen member and the back member so that the two members touch each other, and a set of crosspieces that intersect with the hollow crosspiece are sandwiched between the abdomen member and the back member at the notch.
