Description

The present invention relates to a paving block that is laid on a sidewalk or a plaza.

It is common practice to lay paving blocks on sidewalks and open spaces. The most common is a paving block having a square or rectangular shape, which is laid flat on a ground layer such as sand. However, when the underlayer moves, there is a problem in that a step is generated or a gap is generated to cause a gap such as walking, a wheelchair, or a baby carriage, and a risk of falling is generated. For this reason, a ridge is formed on one side wall of the paving block over the entire longitudinal direction, and a ridge on which the ridge is fitted is formed on the other side wall. Pavement blocks have been developed that are fitted together to be combined together (Patent Document 1).

However, this pavement block is formed with ridges and ridges over the entire longitudinal direction, and there is no deviation in the horizontal direction and the vertical direction in which they are fitted, but the vertical direction orthogonal thereto is not regulated. When the underlayer moves, there is a problem of shifting in the vertical direction.
