Abstract

The invention provides a combined box girder and a manufacturing method thereof, and relates to the technical field of bridge design and construction. The combined box girder comprises a first beam section and a second beam section, a first gap is formed between the first beam section and the second beam section; a first connecting piece and a second connecting piece are arranged in the first gap;the first connecting piece is connected with a flange plate of the first beam section, the second connecting piece is connected with a flange plate of the second beam section, the first connecting piece and the second connecting piece are fixed through a first binding piece, and concrete is poured into the first gap so that a first joint can be formed between the first beam section and the secondbeam section. The first beam section and the second beam section in the combined box beam do not need to be manufactured on site and can be transported to the site after being manufactured, so that the field operation amount is relatively small, the influence on the environment is reduced, and the quality control difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of bridge design and construction, in particular to a composite box girder and a manufacturing method thereof. Background technique [0002] At present, for urban viaducts and interchange hub projects, super-wide box girders and special-shaped bridge structures are inevitable. [0003] According to the road alignment requirements and the changing characteristics of the road's longitudinal and transverse slopes, in the overall layout design of the bridge, the complex special-shaped section at the junction of the ramp needs to adopt a special-shaped widening curved bridge, which is often in the shape of "herringbone" and "pants". structure. [0004] In the past, design schemes such as multi-chamber box girder special-shaped structures were generally adopted. The multi-chamber ultra-wide box girder is a non-standard special-shaped structure with complex structural forces. In addition to bearing bending moment...
