Corrugated steel web I-shaped composite beam for steel-concrete superposed bridge deck

Abstract

The invention relates to a corrugated steel web I-shaped composite beam for a steel-concrete superposed bridge deck. The composite beam comprises a steel-concrete composite bridge deck slab, corrugated steel web I-shaped steel beams and transverse linkage beams; the corrugated steel web I-shaped steel beams are arranged in parallel in the longitudinal bridge direction; a plurality of transverse linkage beams are arranged between every two adjacent corrugated steel web I-shaped steel beams and arranged in parallel in the longitudinal bridge direction; and the steel-concrete composite bridge deck slab is located above the corrugated steel web I-shaped steel beams and the transverse linkage beams. The structural form of a steel-concrete combined system is enriched, the number of steel girders, the number of bridge deck slab steel bars and girder detail structures can be effectively optimized, meanwhile, work such as formwork erection in bridge deck slab construction can be omitted through application of the steel-concrete combined bridge deck slab, the construction procedure is greatly simplified, and the rapid construction requirement of the steel-concrete combined structure is met.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to an I-shaped composite girder with corrugated steel webs on a steel-concrete composite bridge deck. Background technique [0002] In recent years, with the successful application of steel-concrete composite structures in the domestic and foreign bridge markets and the continuous optimization of structural forms, steel-concrete composite structures with fewer main girders have great advantages. Domestic small and medium-span steel-concrete composite structures are mostly multi-girder composite structures. Multi-girder composite structures usually require a large number of stiffeners with complex structures. At the same time, the amount of structural welding and painting is large, and the follow-up maintenance costs are high. The composite structure with few main girders is a new type of steel-concrete composite structure developed by steel-concrete composite bridge techn...
