A kind of construction method of super bridge steel structure bridge

Abstract

The invention discloses a construction method of a steel structure bridge of a super-large bridge, which comprises a bridge deck block body, a main truss, a rope frame, a main tire frame, a rope box, ropes, an auxiliary tire frame, a transverse truss piece and an upper parallel truss The web bar, the bridge deck system block body includes a base plate, a longitudinal diaphragm, a longitudinal web, a small longitudinal girder, a transverse T rib, a bridge deck and a beam, a construction method of a super-large steel structure bridge of the present invention, by using the method Construction The construction of steel structure bridges can effectively avoid the inconvenience caused by the large size and heavy weight of steel structure parts during transportation and construction. Each component can be pre-fabricated and assembled in the factory to ensure more convenience for personnel during construction operations , making the construction of the steel structure bridge more convenient and fast, and at the same time, when the steel structure bridge is spliced, the components of the steel structure bridge can be pre-positioned and calibrated, so as to ensure that the positioning of each structure of the bridge is more accurate during construction, ensure the quality of the bridge, and ensure personnel use.

Description

technical field [0001] The invention relates to the technical field of steel structure bridges, in particular to a construction method for super-large steel structure bridges. Background technique [0002] The super-large bridge composed of steel structure, its load-bearing structure is composed of steel, which can be assembled into prefabricated steel bridges with different loads and different spans according to requirements. [0003] Due to the large size and heavy weight of the steel structure parts of the current steel structure bridge, it is inconvenient for personnel to operate during the transportation and construction process, and personnel cannot splice the bridge in sections, resulting in time-consuming construction of the steel structure bridge Force, and the personnel cannot pre-position and splice the bridge, which will easily lead to inaccurate positioning during the bridge construction process, resulting in quality problems of the bridge and making it unusable...
