PURPOSE:To suppress the lowering of strength and water-stopping performance of a sheathing wall by a method in which a water stopper is continually provided to the periphery of steel tubes for column line and guider for lowering guide is provided to the upper part of the steel tubes connectively and disconnectively. CONSTITUTION:A round steel tube 4 is fitted on the lower end portion of an H- shaped steel 3 and fixed, and uneven water stoppers 5 and 6 to close between the adjacent tubes 4 are fixed to the periphery of the steel tube 4. A cylindrical guider 7 having a projected guider 7a to guide the lowering of the adjacent steel tubes 4 along the H-shaped steel 3 is provided to the upper part of the steel tube 4 connectively and disconnectively. When plural tubes 4 are set, the guider 7 is pulled out and used for others. The connecting work of the steel tubes can thus be exactly and easily made from distance on the ground's surface, and the cost of the construction work can be reduced. |
