Problems solved by technology

[0003] However, due to structural defects, the steel-concrete composite beam will form a negative moment zone at the support. The steel beam in this zone is under compression and the concrete slab is under tension, which easily forms a weak zone. Large tensile stress often leads to cracking of the concrete slab. seriously affect the durability of the structure
[0004] In addition, the crack control requirements are strict in actual engineering. If the crack width exceeds t

Abstract

The invention relates to the technical field of steel-concrete composite beams, and discloses a steel-concrete composite beam connecting piece, a steel-concrete composite beam and a manufacturing method thereof. The steel-concrete composite beam connecting piece comprises a built-in fitting and a clamping member, thebuilt-in fitting and the clamping member are detachably connected, and a flange plate clamping cavity is formed between the built-in fitting and the clamping member. According to the steel-concrete composite beam connecting piece, the steel-concrete composite beam and the manufacturing method thereof, cracking performance and durability of a concrete plate in a negative bending moment area can be greatly improved, and maintenance and replacement of the structure can be facilitated.

Description

technical field [0001] The invention relates to the technical field of steel-concrete composite beams, in particular to a steel-concrete composite beam connector, a steel-concrete composite beam and a manufacturing method. Background technique [0002] At present, steel-concrete composite beams are widely used in bridge engineering. The elastic modulus and deformation properties of the two materials are quite different. Steel-concrete connections form a whole. Conventional connectors all have shear resistance, such as steel connectors, stud connectors, combined connectors, embedded connectors and other modes. The role of the shear connector is to prevent the two from sliding and separating horizontally at the interface, so that the steel structure and the concrete structure with very different elastic moduli can form a whole and work together. [0003] However, due to structural defects, the steel-concrete composite beam will form a negative moment zone at the support. The...
