Installation system and construction method of steel truss arch bridge

Abstract

The invention relates to a steel truss arch bridge installation system, which includes a steel truss group assembly frame, a steel truss underwater installation bracket, a steel truss installation attachment construction platform and a steel truss arch bridge cantilever hanger construction platform; the steel truss group assembly includes Connection groove, connecting steel sheet, tire frame steel plate, tire frame outrigger and outrigger lifting adjustment device; the steel truss underwater installation bracket includes a top adjustment device, a steel pipe connection device and a steel pipe pile; the steel truss installation attachment The construction platform includes hanging baskets, upper rollers, lower rollers, upper panels, lower panels and steel girder splicing plates; the construction platform of the steel truss arch bridge cantilever hanger includes hanger tracks, universal rollers, cantilever arms, bottom plates and clamping rails device. The beneficial effects of the present invention are: the steel truss assembly tire frame provided by the present invention can overcome the problem of unevenness of the pre-assembly site, and the base is stable and does not slip, and tire frames of corresponding sizes can be quickly assembled according to the size of the pre-assembly unit For quick test assembly of steel truss members.

Description

technical field [0001] The invention relates to a steel truss arch bridge, in particular to a steel truss arch bridge installation system and a construction method thereof. Background technique [0002] With the rapid development of my country's urban construction and the improvement of bridge construction technology, steel trusses are more and more widely used in bridge construction. Most of the components of the steel truss arch bridge are prefabricated and installed. The construction involves the pre-assembly and hoisting of many bridge components. When building the main body of the steel structure, it is usually fixed by welding, bolts or rivets. During the connection and installation process, construction personnel need to carry out high-altitude operations at the connection. The formwork and support platform of the traditional installation system are complex, which usually brings a lot of inconvenience to the construction personnel's operation, and it is difficult to i...

Problems solved by technology

During the connection and installation process, the construction personnel need to carry out high-altitude operations at the connection. The formwork and support platform of the traditional installation system are relatively complicated, which usually brings a lot of inconvenience to the construction personnel's operation, and it is difficult to improve work efficiency.
