Steel hidden beam type slab-column structure and connecting structure thereof

Abstract

The application discloses a steel hidden beam type slab-column structure and a connecting structure thereof, and comprises a column of a steel column cap as a vertical load-bearing framework, the column penetrating through a central reserved hole of the steel column cap and being rigidly connected with the steel column cap, the steel column cap comprising upper and lower spaced-apart upper flange ring plates, lower flange ring plates and vertical multiple stiffening plates, the upper flange ring plates, the lower flange ring plates and the stiffening plates being enclosed to form a hollow prism structure; further comprising a steel beam connected to a middle position of the steel column cap. The application adopts a steel hidden beam + slab-column hybrid system, completely buries the steel beam in a concrete floor to form a hidden effect, and utilizes the punching shear resistance of the steel column cap joint to realize indoor beamless, high integral ductility, punching shear resistance and structural redundancy of the floor system, and the structural performance is more optimal; secondly, the application is convenient for standardized design and semi-assembly construction, can greatly reduce on-site operation, and is higher in construction efficiency; the net height of the building is low, the steel consumption is low, and the application is especially suitable for the floor system of a multistory building or a basement using a pure steel column or a steel pipe concrete column.
