The anti falling beam stopper mainly includes a beam body tensile seat, a pier and abutment tensile seat, and a circular chain. The two ends of the circular chain are respectively connected to the beam body tensile seat and the pier and abutment tensile seat, and the circular chain is wrapped with buffer rubber. The pre embedded anchor bars are installed on the tensile seat of the beam body, which is not used for steel truss beams. For the tensile seat of the beam body, the form of a single connecting ear has poor stability, insufficient connection strength, and short practical life.

The anti falling beam blocking blocks have middle and side piers, which are divided into continuous beams and single double track beams. The anti-corrosion requirements for bridge anti falling beam blocking blocks are zinc infiltration or multi-element alloy co infiltration. The anti falling beam should first understand the position, specifications, and quantity of the embedded parts, select qualified raw materials, conduct necessary mechanical performance tests, chemical composition analysis, and visual quality inspection before processing, and then make and fix according to the standards.
