[0002] A road expansion joint refers to a structural joint set up at an appropriate position along the construction joint direction of a road or structure to prevent road components from expanding or contracting due to changes in climate temperature, causing cracks or damage to the structure. An expansion joint divides building components above the foundation, such as walls, floor slabs, roofs, etc., into two independent parts, allowing the road or structure to expand and contract horizontally along its length.

The utility model can provide effective buffering for the longitudinal offset generated between the first beam body and the second beam body through the joint action of the buffer block and the sliding sleeve, effectively improve the longitudinal deformation generated between the first beam body and the second beam body, and can provide buffering for the lateral deformation generated between the first beam body and the second beam body through the joint action of the buffer block and the sliding block, effectively improve the lateral deformation generated between the first beam body and the second beam body, effectively maintain the flatness of the road surface, and improve the safety of vehicle driving.

At the same time, the road cracks will expand outward over time, and the expansion joints cannot expand outward according to the increase of the road cracks. For this reason, we propose a municipal road expansion joint to solve the above problems. Utility Model Content
