However, the railing structure cannot be connected to the bridge deck by bolts, and the railing needs to be welded to the bridge deck. Repeated use will cause great damage to the bridge deck steel plate. In actual use, the edge I-beams of traditional bridge decks are prone to deformation during the hoisting process, and the main beam spacing is large. Long-term use will cause large areas of the bridge deck to sag, which is difficult to repair. In this solution, the railing is set as a snap-on base, and the base is inserted into the beam from both ends of the beam. The adaptability of this base is not high, and the bases of beams of different models are not compatible. Utility Model Content
