Characteristics of comb type bridge expansion joints

1. The comb shaped expansion joint surface laminate is a comb shaped anti-skid groove steel plate, which is a supporting structure meshing with each other from the left and right out of the bridge deck gap. The structural stiffness is large and can withstand large horizontal displacement.

2. The reserved height of comb expansion joint is low. The comb type expansion joint can be installed within the height of the bridge deck pavement, and there is no need to reserve a notch in the beam body, which greatly facilitates the design and construction.

3. The expansion joint has a wide range of application. It can be used on both new and old bridges, especially for the replacement of large displacement rubber plate expansion device of old bridges.

4. The car runs smoothly and comfortably without jumping and noise.

5. The expansion joint components are easy to transport and install, and do not need to be transported by extra long vehicles or loaded and unloaded by cranes.
