Abstract

The invention discloses an aluminum alloy pedestrian overpass structure and mounting and construction methods thereof. A concrete foundation pile is arranged on the lowest side of a base structure, the upper side of the foundation pile is connected to a bearing platform, an overpass pier is arranged above the bearing platform, a preburied anchor plate arranged above the bearing platform is fixedlyconnected to a bottom plate of a cover plate of the overpass pier, the column is arranged above the bottom plate of the column, a cover beam is arranged above the column, the cover beam is of a steelwelded hollow structure, a bottom plate of the cover beam is arranged below the cover beam, a top plate of the cover beam is arranged above the cover beam, side plates of the cover beam are arrangedaround the cover beam, a plurality of slab with haunched ribs are arranged in an inner cavity of the cover beam, and two sides above the cover beam bear a bottom beam of the overpass. The aluminum alloy pedestrian overpass structure provided by the invention has the advantages that the overpass structure is stable, small in vibration, high in pressure bearing ability and convenient and rapid to mount and construct and does not affect urban traffic.

Description

technical field [0001] The invention relates to the field of building structures, in particular to an aluminum alloy pedestrian bridge structure and an installation and construction method thereof. Background technique [0002] Traditional pedestrian bridges mainly adopt steel structure or concrete structure, which has the advantages of good rigidity, firmness and stability, but steel structure bridges generally face durability problems caused by corrosion and high maintenance costs, and concrete structure bridges have long construction time , The construction project is cumbersome and affects urban traffic and other shortcomings. Therefore, it is of great significance to the development of the city to find a new type of urban pedestrian bridge with comparable strength, good durability, good landscape effect, and short construction and installation time. The advantages of aluminum alloy materials, such as light weight, high strength, corrosion resistance, low maintenance co...
