<P>PROBLEM TO BE SOLVED: To solve the problem that when a conventional scaffold using suspension chains is applied to a water-area structure, not only a constructing operation for a scaffold, but also various operations on the scaffold having been constructed are hard operations accompanied by danger, a decrease in operation efficiency is not evitable to result in an increase in operation time. <P>SOLUTION: A connection member 14 which connects steel pipe piles 13 of a water-area structure 11 to each other and mounted not to move along the steel pipe piles 13 bears the load of a scaffold constructed under a superstructure, or suppresses fluctuations of a scaffold constructed with a floating body under the superstructure. The connection member 14 which bears the load of the scaffold is a rod-like member which freely extends and contracts in a member axis direction, and attachable and detachable between existent steel pipe piles 13. A scaffold support member 15 is locked to the connection member 14 as a fixed base 23 comes into contact with the connection member 14 by closing a base piece 23a, and the opening/closing operation thereof is performed by a support member 24 mounted on the fixed base 23. <P>COPYRIGHT: (C)2013,JPO&INPIT |
