<P>PROBLEM TO BE SOLVED: To provide a support which can dispense with both of a hanging chain and a strut material, which can reduce a tensile force applied in the length direction of a bolt, and which can hold a tread of a scaffold board for use in a worker's work in an approximately horizontal state. <P>SOLUTION: This support comprises a sleeper material 6 which is arranged on the downside of an overhanging portion 3a of a form so as to support the concrete form of an overhanging portion of a floor slab 2, provided in such a manner as to overhang from an upper flange portion 1b of a main girder 1, and a length-adjustable diagonal member 7 for supporting the sleeper material from an obliquely lower side. In the support, a through bolt or a pin is laterally inserted between an obliquely and vertically-long slot and a through-hole provided at one end of the sleeper material, via a retainer fitting provided with the obliquely and vertically-long slot with an upper end inclined in the center of web direction of the main girder; and thus, the sleeper material is attached to the retainer fitting. <P>COPYRIGHT: (C)2010,JPO&INPIT |
