A method for assembling truss bridge segments

Abstract

The invention discloses an assembling method of truss bridge segments. The method comprises the following steps of respectively assembling two main trusses; assembling bridge surface plates; performing temporary tightening on two lower crossbeams, and respectively connecting two ends of a plurality of lower parallel connectors with the two lower crossbeams; fixing a plurality of crossbeam web members to the two lower crossbeams; performing temporary fixing on the two main trusses, two lower crossbeams and the crossbeam web members; connecting each upper crossbeam with lateral nodes of the corresponding main truss, and connecting each upper crossbeam with the corresponding crossbeam web member; and connecting the bridge surface plates with the main trusses, and connecting a stringer adapterplate of each upper crossbeam with the corresponding bridge surface plate, so as to complete the assembling of the truss bridge segments. According to the assembling method disclosed by the invention, three-dimensional assembling is firstly performed on an inner site, then integral hoisting is sequentially performed, the line shape is adjusted, and circumferential seam connection is performed; through the adoption of the assembling method disclosed by the invention, the aloft work is integrally assembled in a ground, planar and massive manner, and aloft work is reduced, so that the efficiencyis improved, the assembling quality is improved, the assembling speed is accelerated, and requirements for standardized and batch production of long-span steel truss beam are met.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a method for assembling truss bridge segments. Background technique [0002] The traditional assembly process of truss bridges is to assemble the rods one by one at the bridge position. This assembly has problems such as large amount of high-altitude operations, difficulty in high-altitude adjustment, low assembly efficiency, and a large amount of traffic resources. It is no longer suitable for large-span steel truss girders. The demand for mass assembly. Contents of the invention [0003] The present application provides a method for assembling truss bridge segments, which solves the technical problem in the prior art that the truss bridge segments are assembled sequentially by rods at the bridge position, which cannot be applied to the large-scale assembly of large-span steel truss girders. [0004] The present application provides an assembly method for truss br...
