LAMINATION BLOCK, LIGHTWEIGHT BANKING STRUCTURE USING LAMINATION BLOCK, AND METHOD FOR CONSTRUCTING LIGHTWEIGHT BANKING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a lamination block used in a lightweight banking structure and comprising a plurality of polystyrene-based extrusion foam boards that can reduce occurrence of warpage even if the lamination block are left for a long time in a construction process.;SOLUTION: In a lamination block 10 comprising at least two polystyrene-based extrusion foam boards, the thickness of a polystyrene-based extrusion foam board 21 on one face is made smaller than the thickness of the other polystyrene-based extrusion foam board 22, and by laying the lamination block 10 with one face directed upward, a contraction amount of the polystyrene-based extrusion foam board 21 on the top face is reduced even when the lamination block is left for a long time and a surface temperature is increased. At the same time, stress applied to the polystyrene-based extrusion foam board 21 at the lower part is reduced and warpage generated in the lamination block 10 is reduced.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
