Background
The expansion joint, which is a building expansion joint, is a structural joint provided at an appropriate position along a building or a construction joint direction of the building in order to prevent a structure from being cracked or damaged due to a change in temperature (thermal expansion or contraction) of the building. The expansion joint is used for dividing building components above a foundation, such as a wall body, a floor slab, a roof (except a wooden roof) and the like into two independent parts, so that the building or the structure can horizontally expand and contract along the long direction, the reasonable selection of the joint with proper expansion and contraction amount is very important, and the expansion device is easy to damage when the joint is larger. Too large or too small a gap is used, and the gap is not adjusted in consideration of the temperature at the time of installation. Especially, the plate-type rubber expansion device is easy to damage. Cracks often appear in the surface course even when continuous bridge decks are paved. Thus. The method is to pre-cut the bridge surface, set the joint, or use the softer paving layer to absorb the crack, or install the small-sized telescopic device to solve the problem. In the case of a large longitudinal slope, if a structure that accommodates vertical displacement is not provided, a defect is likely to occur and damage is likely to occur.
However, the existing covering structure for the bridge expansion joint has some defects in the using process, the existing equipment generally only uses one damping rubber plate to fill the gap when in use, and if the damping rubber plate is damaged due to overlong time, the gap cannot be protected due to the equipment, so that cracks appear in the building and the safety of the building is influenced.
