Description

Technical Field

[0001] The utility model relates to the technical field of concrete components, in particular to a steel-concrete connection structure. Background Art

[0002] Steel-concrete structure is a combination of steel and concrete structures, with the steel located inside the concrete structure. During the construction of steel-concrete structure, the steel and the steel bars need to be connected and fixed through stirrups or tension bars. Since the steel is welded by steel plates, there is no fulcrum on its surface for the stirrups to fix. In order to connect the steel and the steel bars, the current practice is to open holes in the steel to allow the stirrups to pass through, which will weaken the strength of the steel and create unsafe factors; or directly weld the stirrups to the surface of the steel, which will result in excessive welding and high labor costs.
