Abstract

The invention relates to a butt joint prefabricated combined beam and a construction method. The butt joint prefabricated combined beam comprises a steel main beam, and the steel main beam comprises asteel beam bottom plate and a steel beam web fixed to the steel beam bottom plate; a bottom-layer bridge deck slab is included and arranged at the top of the steel beam web, and the bottom-layer bridge deck slab comprises a concrete web and a concrete top plate; the steel beam web is in butt joint with the concrete web through transverse shear nails; and the height of the steel beam web and the height of the concrete web are changed in the longitudinal bridge direction. By adjusting the heights of the steel beam web and the concrete web, a structural stress is more reasonable, and the durability of the combined beam structure is enhanced while the shear resistance and the pulling resistance of the steel-concrete combined beam are enhanced.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a butt joint prefabricated composite beam and a construction method. Background technique [0002] At present, the steel-concrete composite bridge is a bridge structure in which the concrete bridge deck is connected with the steel girder through shear connectors to form an overall joint force. Compared with traditional concrete bridges, steel-concrete composite bridges have light weight, good seismic performance, fast construction speed, significantly increase the clearance under the bridge, and improve the bridge landscape effect; compared with steel bridges, they are more economical and the overall flexural bearing capacity Improvement, avoiding the problem of fragile steel bridge deck pavement, and has been widely used in bridge construction. For multi-span continuous beams, the support position has obvious negative bending moment effect, and the mid-span position has obviou...
