AI Technical Summary
The adjacent beam ends of integral bridges are prone to misalignment and deformation under lateral action, which leads to bridge structural instability and affects train running stability. The existing shear tenon device has insufficient constraint stiffness and cannot adapt to the corner deformation of the beam ends.
An anti-misalignment component is installed between two adjacent beams, including a first anti-misalignment component and a second anti-misalignment component. The components form lateral and vertical limits through the interlocking of concave and convex teeth to prevent lateral misalignment of the beam ends, while allowing longitudinal and angular displacement.
It effectively avoids lateral displacement and deformation at the beam ends, improves the stability of the bridge structure and the safety of traffic, and maintains the smoothness of the track on the bridge.
