Reinforced board for paving blocks

Abstract

This article is used when laying paving blocks on the ground. It is a reinforcement plate for paving blocks that is placed between the ground and the paving blocks to prevent the blocks from shifting or creating steps, and to create gaps between the paving blocks. The article has a base plate that is roughly square in plan view, and is provided on its upper surface with roughly vertical joint plates that create gaps between the paving blocks, and the base plate has multiple small protrusions on its upper surface. In addition, the base plate has roughly circular ribs on its lower surface when viewed from the bottom.
