AI Technical Summary
In existing straddle-type rail transit systems, the change in the angle at the connection between the finger plate and the beam end increases the risk of anchor bolt pull-out, affecting the overall stability and safety of the rail transit system.
The design employs a pre-reserved gap between the first and second panels and the connecting structure. The first and second panels are movably snapped together by the connecting structure to form a three-section self-locking finger plate, which disperses and releases the corner load at the end of the track beam, and avoids the fixed structure bearing unnecessary upward force.
It has improved the overall stability and safety of the rail transit system, reduced risks in the production process, and ensured long-term safe and efficient operation.
