SYNTHETIC RESIN FOAM BLOCK FOR LIGHTWEIGHT BANKING AND LIGHTWEIGHT BANKING STRUCTURE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a synthetic resin foam block which can constitute a lightweight banking structure having a flat side wall and good external appearance without the need for troublesome positioning work and which does not affect the side wall even if compressed and deformed.SOLUTION: In a synthetic resin foam block, a first side face 15 on the side of a side wall of a main body 11 comprising a synthetic resin foam is provided with a metallic face bar 12. In the synthetic resin foam block, first steps 14 and 14 are formed by cutting off the upper end and lower end of the first side face 15, and first grooves 13 and 13 are formed along the first side face 15 in the first steps 14 and 14. The synthetic resin foam blocks mutually adjacent in the vertical direction are connected by inserting a first spline 22 into the first grooves 13 and 13.SELECTED DRAWING: Figure 6
