Description

TECHNICAL FIELD

[0002] It is known that in order to meet the needs of bridge beam deformation, bridge expansion joint devices are generally installed between the two beam ends of a bridge, between the beam ends and abutments, or at the hinged positions of the bridge.

[0003] A highway bridge comb plate expansion device disclosed in CN210315205U is currently available. Many existing bridge expansion devices generally have longitudinal displacement, longitudinal rotation, and horizontal rotation three-directional displacement functions, which can meet the requirements of general bridges for bridge expansion devices. However, some large bridges will produce lateral displacement and torsional displacement in addition to longitudinal displacement, longitudinal rotation, and horizontal rotation during use due to temperature, heavy load, wind load, and earthquake effects. For example, a bridge will produce large lateral displacement and torsion under the influence of an earthquake, and a bridge will also produce torsional displacement under heavy or uneven load. Although existing technologies have disclosed bridge expansion devices with longitudinal displacement, lateral displacement, longitudinal rotation, and horizontal rotation, the lateral displacement capacity of existing expansion devices is small, making it difficult to meet the demand for large lateral displacement caused by earthquakes, and lacking torsional displacement function. Accordingly, in order to avoid damage to the expansion device and the beam, the bridge expansion device also needs to have a large lateral displacement and torsional displacement function along the bridge direction. In summary, the existing bridge expansion device needs to be further improved. SUMMARY
