Aluminum alloy pedestrian overpass

Abstract

The invention relates to an aluminum alloy pedestrian overpass which comprises a bridge body made of aluminum alloy materials, ladder corridors, ladder way straight rods, a ceiling, decorative grid rods and handrails, each truss body unit comprises a plurality of groups of parallel transverse trusses and vertical trusses on the two sides, the transverse trusses are arranged at certain intervals, and the vertical trusses on the two sides are perpendicular to the transverse trusses. Meanwhile, the stair steps, the bridge body step plates, the stairway longitudinal beams, the decorative grid rods, the bridge body handrails, the stairway handrails and the water collecting tanks which are convenient to install are arranged, assembling is rapid and convenient, the strength of the bridge body structure is improved, the self weight of the bridge body is light, the transportation cost is reduced, and the foundation cost of the ground is reduced; the on-site construction period is short, the speed is high, the installation difficulty is small, long-time road sealing and barrier setting are not needed, the structure corrosion resistance is good, the maintenance cost is extremely low, the aluminum alloy materials are renewable after disassembly, and the disassembled aluminum alloy materials are high in recovery rate and low in recovery treatment cost.

Description

technical field [0001] The invention relates to the field of overpasses, in particular to an aluminum alloy pedestrian overpass. Background technique [0002] Traditional pedestrian bridges are usually constructed of reinforced concrete, or steel structures are connected by bolts or welded on site. Reinforced concrete components are heavy in weight, long in construction period and low in plasticity. They are cast on site and generate a lot of construction waste during construction. , not environmentally friendly; the construction period is long, and the road needs to be blocked for a long time, causing traffic obstacles along the line; the structure is heavy, the aesthetics are poor, and the transportation cost is high. Disadvantages of steel structure pedestrian bridges are easy to corrode, poor durability, high post-maintenance cost; low recovery value and recovery rate, welding operation is not conducive to environmental protection, and the structure is heavy.

[0002] Traditional pedestrian bridges are usually constructed of reinforced concrete, or steel structures are connected by bolts or welded on site. Reinforced concrete components are heavy in weight, long in construction period and low in plasticity. They are cast on site and generate a lot of construction waste during construction. , not environmentally friendly; the construction period is long, and the road needs to be blocked for a long time, causing traffic obstacles along the line; the structure is heavy, the aesthetics are poor, and the transportation cost is high

Disadvantages of steel structure pedestrian bridges are easy to corrode, poor durability, high maintenance cost in the later stage; low recovery value and recovery rate, welding operation is not conducive to environmental protection, and the structure is heavy
