Description

Technical Field

[0001] The utility model relates to the field of steel structure overpasses, in particular to a modularly assembled steel structure overpass. Background Art

[0002] Pedestrian overpass is also called pedestrian flyover. It is usually built in areas with heavy traffic and dense pedestrians, or at intersections, squares and railways. Pedestrian overpasses only allow pedestrians to pass through, and are used to avoid conflicts when traffic and pedestrian flows intersect, ensure people's safe crossing, increase vehicle speed and reduce traffic accidents. Since pedestrian overpasses are generally built in areas with heavy traffic, and conventional overpasses take a long time to build, they affect normal traffic order and cause traffic jams. For this reason, a modular assembled steel structure overpass is needed to facilitate rapid construction.

[0003] After searching, Chinese patent announcement number: CN212294302U discloses a detachable steel structure overpass, including three support modules and two escalator modules, the side of the support module is provided with an escalator module, the three support modules each include four I-beam support seats, and the four I-beam support seats are distributed in a rectangular array, the opposite surfaces of each two I-beam support seats are fixedly connected with inclined reinforcing rods, the two sides of the I-beam support seats are fixedly connected with mounting plates, and the mounting plates of adjacent support structures are bolted. The detachable steel structure overpass, by providing support modules and escalator modules, is convenient for quickly fixing multiple support modules together with bolts according to the width of the road, and fixing the escalator bolts on the side of the support module. The modular assembly enables the overpass to reduce the construction period when dismantling and installing, and achieves the effect of convenient disassembly and assembly, thereby avoiding road congestion caused by long-term construction.

Therefore, a modularly assembled steel structure bridge is proposed to solve the above problems. Utility Model Content
