<p><P>PROBLEM TO BE SOLVED: To provide a construction method of lightweight banking, capable of preventing deformation or falling of a wall surface material due to contraction of polyurethane foam filled and foamed on site and facilitating construction. <P>SOLUTION: A movable partition member is piled up on a fixed partition member fixed to a column 14 and is tentatively fixed, urethane foam is filled and foamed between the movable partition member and natural ground, and even when the urethane foam is contracted, since the tentatively fixed movable partition member follows it, the fixed partition member, the column 14 and a wall surface material 13 are prevented from being deformed or the like. Then, polyurethane foam is filled and foamed in a narrow and shallow gap formed with the fixed partition member by the following of the movable partition member in the next step, influence of contraction is suppressed in each step, and the lightweight banking is constructed without generating a gap. By repeating fixing installation of the fixed partition member and upper part tentative fixation of the movable partition member in each step according to a height for one step of the polyurethane foam and repeatedly filling and foaming the polyurethane foam, the construction is completed. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
