BEARING ANCHOR STRUCTURE TO PREVENT A FALLING BRIDGE OF A STEEL BOX GIRDER BRIDGE

摘要

The present invention relates to an anti-falling bearing anchor structure of a steel box girder bridge. More specifically, the slip-type bearing is installed on both sides of the longitudinal direction of the steel box girder so as to prevent an annual fall of the bridge. It is possible to minimize the size of the bridge and does not affect the stretch of the bridge, and especially the steel box used as the bearing of the bridge is not twisted and designed to be installed on the aging bridge, the fall prevention bearing anchor structure of the steel box gutter bridge .;The present invention, in the steel box girder bridge, the steel box girder 1 and the steel box girder 2 is provided with an anti-falling bearing anchor in the gap, while the concrete slab and steel installed on the upper portion of the steel box girder 1 In the concrete slab installed on the upper part of the box girder 2, a bridge seam is installed in the gap, and the anti-falling bearing anchor is coupled to the steel box girder 1,2 by the fastening bolt 1 and the fastening plate 2 by the fastening bolt. Steel box girders, characterized in that the bearing bolt is fastened to the anchor bolt hole of the transverse bracket welded to the fastening plate 1 and the bearing hole of the bearing bracket welded to the fastening plate 2 to couple the fastening plate 1 and the fastening plate 2. Provides a bridge's anti-fall bearing bearing structure.
