Description

Technical Field

[0001] This utility model relates to the field of building structure engineering technology, and in particular to a composite structural panel. Background Technology

[0002] Shear wall structures possess advantages such as high lateral stiffness, high load-bearing capacity, and good seismic performance, making them widely used in high-rise civil buildings. Reinforced concrete shear walls were the earliest type of shear wall unit, and their use remains strong. However, due to the brittle fracture characteristics of concrete, their ductility under seismic loads is poor. Compared to reinforced concrete shear walls, steel plate shear walls offer improved load-bearing capacity and ductility, along with good hysteresis performance and energy dissipation capacity. However, to fully utilize the mechanical and economic advantages of steel plate shear walls, the steel plate thickness should not be excessive, and measures must be taken to prevent premature buckling without yielding, such as adding stiffening ribs, concrete cap plates, or using corrugated steel plates. Subsequently, various forms of shear walls composed of steel plates and concrete have rapidly developed, as they can fully utilize the advantages of both materials through a combined effect, making them actively used in the high-rise building market.

[0003] This application provides a novel composite structural slab composed of steel plate and concrete, which can enhance the shear resistance of the structural slab, improve the anti-slip ability between the steel plate and concrete, and has the advantages of simple structure and easy construction.

[0031] The combined structural slab 100 provided in this embodiment of the present invention has good longitudinal shear resistance of the closed profiled steel sheet 110, which improves the shear resistance of the combined structural slab 100. In addition, part of the concrete 120 is embedded between two adjacent ribs 111 of the closed profiled steel sheet 110, which improves the connection strength between the concrete 120 and the closed profiled steel sheet 110. Under the extreme allowable design load, there will be no slippage between the closed profiled steel sheet 110 and the concrete 120.

The combined structural slab 100 provided in this embodiment of the present invention has the advantages of simple structure and easy construction.

[0032] In this embodiment, the composite structural panel 100 can be used as a wall panel or a floor panel. When the composite structural panel 100 is used as a wall panel, concrete 120 is poured into the cavity of the rib 111 to improve the support of the wall panel.
