[0002] An expansion joint refers to a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion and contraction). The expansion joint structure is widely used in construction engineering, bridge engineering, road engineering and other fields. The expansion joint structure can effectively absorb and buffer the deformation of buildings, bridges, roads and other structures caused by temperature changes, foundation settlement, concrete shrinkage and other factors, avoid cracks and damage to the structure, and reduce the safety hazards caused by structural deformation, ensuring the normal use of buildings, bridges and roads. In short, the expansion joint structure plays an important role in engineering fields such as buildings, bridges and roads. In the existing expansion joint structure, the location of the expansion joint structure is relatively narrow, and in order not to affect the driving of passing vehicles, the expansion joint plate is generally set close to the ground, and there is not enough operating space to disassemble the expansion joint structure. Therefore, we propose an expansion joint structure that is easy to maintain. Summary of the invention

[0033] Among them, a groove 44 is opened at the bottom of the annular plate 43, a limit ring 42 is fixedly installed on the outer side of the fixed plate 41, and a circular groove for the limit ring 42 to pass through is opened on the expansion joint plate 3.
