<p>PURPOSE:To facilitate handling and permit the use as a member having a sufficient strength in assembled state by constituting a pillar-shaped member from a plate-shaped member and a wedge type connecting member whose both edges are engaged with an opened hole part formed on the plate-shaped member and both hole parts. CONSTITUTION:A pair of plate-shaped member 7a and 7b are opened nearly perpendicularly by a plurality of hinges 13 installed in the axial direction, and in this state, both the edges of a wedge-type connecting member 14 are engaged with the opened port parts 7c and 7d, and a pillar-shaped member 7A having an L-figure-shaped section is obtained. When this pillar-shaped member 7A is transported, the wedge type connecting member 14 is demounted, and set close to the free edges of both the plate-shaped members 7a and 7b around the hinge 13. Then, both the plate-shaped members 7a and 7b are put into a superposed thin box form, and handling and transport are facilitated. Since the pillar-shaped member 7A is obtained from two plate-shaped members 7a and 7b, use of a bolt is prevented, and the engagement connection by the wedge type connecting member 14 is used, and assembly is exceedingly facilitated, and a curving device can be assembled in a short time.</p> |
