手。[Claims for Utility Model Registration] 1. A pair of vertical members fixed to a post-fabricated material on the road surface via an anchor member at a joint of a road, bridge, etc., and a pair of vertical members attached to the end portion of the vertical member on the road surface side. In a vertical road expansion joint made of road rubber, the part of the road rubber that comes into contact with the post-applied material has a JIS hardness that is higher than the JIS hardness of the road rubber.
A vertical expansion joint for roads, characterized by integrally provided with hard end reinforcing rubber. 2 JIS hardness of the road rubber is 50° to 60°
In contrast, the JIS hardness of the end reinforcement rubber is 70°~
The vertical expansion joint for roads according to claim 1, characterized in that the angle is set at 90°. 3. The vertical expansion joint for roads according to claim 1, wherein the road surface side of the end reinforcing rubber is extended horizontally to form a substantially triangular shape.
