Block product modulo stopping construction method

摘要

PURPOSE:To enable reduction of the weight of a block by a method wherein the block is formed of foamed styrol, and a coupling part for intercoupling the blocks and a hole part through which floor excavated soil is charged are formed in the block. CONSTITUTION:An H-block is formed of a foamed styrol material. The thickness of a front wall 1 is made equal to that of a rear wall 2, and the length of a lateral wall 3 is set to a value two times as long as the thickness of the front wall 1. A hole parts 4, 5, and 6 are formed in the front wall 1, the rear wall 2, and the lateral wall 3, respectively. Arcuate notch parts 7 are formed on both sides of the lateral wall 3, and the notch parts 7 of the adjoining H- blocks are joined together to form a hole pert. This constitution reduces weight and enables prevention of settling under weight.
