Embodiment
The technical solution of the utility model is further elaborated with reference to embodiment and accompanying drawing.
Embodiment 1
A kind of sealing belting of bridge expanssion joint is present embodiments provided, as shown in figure 1, including elastic water-proof waterstop
1 is zigzag knot with the wearing layer 2 being arranged on the elastic water-proof waterstop 1, the upper surface of elastic water-proof waterstop 1
Structure, with the convex portion 5 and recess 6 being alternately arranged, the convex portion 5 and recess 6 are set by bridge lateral direction, in the recess 6
Fill PU glue；The first side 3 and second side 4 of the elastic water-proof strip 1 are in contact with bridge expanssion joint two sides respectively, institute
State and fluted 7 are set in first side 3 and second side 4, the groove 7 is set by bridge lateral direction.The convex portion 5 and recessed
