External plate mounting structure of steel structure bridge

The invention discloses an external plate installation structure of a steel structure bridge, and relates to the technical field of bridge external plate installation, the external plate installation structure comprises a cover plate used for splicing gaps between adjacent prefabricated bridge body side protection baffles, and the width of the cover plate is larger than that of the gaps between the adjacent prefabricated bridge body side protection baffles; the side wall, facing the partition part, of the limiting part is provided with a first buffering piece located in a gap between adjacent prefabricated bridge body side protection baffles, one end of the connecting rod is fixed to the side wall, facing the partition part, of the limiting part, and the two L-shaped butt joint blocks are symmetrically fixed to the two ends of the arc-shaped elastic rod correspondingly. The ends of the positioning pins extend out of the second adjusting holes and then are fixedly connected with the side walls of the correspon
