<p>PURPOSE:To enhance efficiency as a contact material, by connecting a plurality of embossed plates, each of which is constituted so as to allow concave surfaces and convex surfaces to correspond across both front and back surfaces at plural places, in the up-and-down direction and the left-and-right direction by hinges. CONSTITUTION:A laminated block system is formed by connecting embossed plates P in the up-and-down direction by hinges 3a and in the left-and-right direction by hinges 3b. Each embossed plate P is constituted by forming oblique fib like convex surfaces 2a and grooves 2b to a net plate made of a synthetic resin symmetrically on front and back surfaces. The embossed plates P connected in the up-and-down direction are not closely contacted to each other when folded back in the up-and-down direction and combined in a direction overlapped so as to take the interval corresponding to the height of one rib like convex surface 2a therebetween while the embossed plates P adjacent in the left-and-right directions are combined in a direction overlapped in a closely contacted state when folded back to each other.</p> |
