<P>PROBLEM TO BE SOLVED: To provide a marine scaffold capable of facilitating carrying. <P>SOLUTION: The scaffold 10 includes: lengthwise scaffolding boards 11; stringer boards 12 which are provided to protrude on the rear face 11b side of the scaffolding board 11 in use and which is tiltable in the longitudinal direction of the scaffolding board 11; wires 17a, 17b structured so that both ends thereof are fixed with tension applied and so as to be applied to the end of the board 12. The wires 17a, 17b retain the board 12 provided so that the stringer board 12 does not tilt when a load is applied from a surface 11a side of the scaffolding board 11 in use. Accordingly, when the inside of a marine tank, for example, is inspected using the scaffold 10, when a load is applied from the surface 11a side of the scaffolding board 11, the load is supported by the tension of the stringer board 12 and the wires 17a, 17b. Thus, the necessity of producing the scaffolding board 11 to be thick and to be formed from a material with high strength can be reduced. <P>COPYRIGHT: (C)2011,JPO&INPIT |
