Construction method for dismantling aluminum alloy pedestrian overpass
The invention relates to the technical field of construction, in particular to a construction method for dismantling an aluminum alloy pedestrian overpass, which comprises the following steps of: S1, dismantling accessory structures of a main truss and a stairway truss of the overpass; s2, a fence is vertically arranged on a road at one end of the overpass, and traffic guide and change are conducted; s3, calculating the gravity centers of the main truss and the stairway truss of the overpass; and S4, according to the gravity center of the main truss and the gravity center of the stairway truss, the lifting points of the main truss and the stairway truss are determined correspondingly, so that the main truss and the stairway truss are lifted correspondingly, and the main truss and the stairway truss are moved into the fence. According to the construction method for dismantling the aluminum alloy pedestrian overpass, the dismantling efficiency of the overpass can be improved, and the influence on traffic is reduced.
本发明涉及施工技术领域，尤其是一种铝合金人行天桥拆除的施工方法，包括下述步骤：S1.对天桥的主桁架及梯道桁架的附属结构进行拆除；S2.在天桥一端的道路立设围挡，且进行交通的导改；S3.计算天桥的主桁架及梯道桁架的重心；S4.根据所述主桁架及所述梯道桁架的重心分别确定所述主桁架及所述梯道桁架的吊点，以分别对所述主桁架及所述梯道桁架进行吊装，且将所述主桁架及所述梯道桁架移动至所述围挡内。本发明的一种铝合金人行天桥拆除的施工方法，能够提高天桥的拆除效率，减少对交通的影响。
