Quickly assembled pedestrian bridge

Abstract

The present invention provides a fast-assembled overpass, which belongs to the technical field of urban traffic facilities, including bridge piers, columns, bridge arches, bridge decks, and stairways. The bridge piers are made of steel structure pipe piles, and columns are connected to the upper part thereof. The columns are used to fix the bridge arches, bridge decks, and stairways. The overpass has the advantages of low investment, fast construction, continuous traffic, no disturbance to the people, low maintenance, and few hidden dangers. The on-site installation can be completed within 1 hour at the fastest, and the usual installation only takes a few hours. It does not hinder traffic, and it is also very convenient to disassemble and move. It also has many advantages such as large bearing capacity, diversified design and shape, increased urban beauty, and long service life. It can be widely used in urban overpasses, especially temporary or long-term traffic auxiliary facilities in urban pedestrian-dense areas. It is also convenient for specialized batch production in factories.
