Abstract

The invention discloses a construction method of an upper structure of a steel-concrete overlapping beam. The method includes the following steps of erection of flexible temporary buttresses, mounting of supporting seats, mounting of pre-embedded parts, hoisting of steel beams, fine adjustment of the beams, beam section welding, first-time removing of supports, pouring of bridge deck slab sections, prestress tension, second-time beam lowering and removing of the flexible temporary buttresses. According to the construction method of the upper structure of the steel-concrete overlapping beam, the construction process of erection of the steel beams and a large-tonnage steel beam fine adjustment device by means of a flexible buttress method has the advantages of convenient operation, fast construction and the like, devices that are used in the construction method are common devices that are made of common materials and can be applied to common bridge construction sites, costs are low, and the application range is wide.

Description

technical field [0001] The technical field of building construction of the present invention specifically refers to a construction method for the superstructure of steel-concrete composite beams. Background technique [0002] With the development of society and the progress of economy, there are more and more bridge projects, and at the same time, bridge engineering has gradually become one of the important factors to promote my country's economic development. Among them, the steel-concrete composite beam system is a bridge system that has been widely used in recent years. However, the existing construction methods for steel-concrete composite beams are difficult to guarantee the construction quality, and the cost is high and the operation is complicated, which delays the construction progress to a certain extent. . Contents of the invention [0003] The object of the present invention is to provide a construction method for the superstructure of steel-concrete com...
