Strip-shaped grate concrete filled steel tube combined structure shear wall and preparation method thereof

Abstract

The invention provides a strip-shaped grate concrete-filled steel tube combined structure shear wall, which comprises a strip-shaped grate steel tube wall plate and reinforced concrete columns inside tubes. A corrugated sheet steel and a plurality of steel sheet strip cover plates are vertically welded, so that the strip-shaped grate steel tube wall plate is formed; a vertical groove of the corrugated sheet steel is covered by the steel sheet strip cover plates, and then a plurality of cavities are formed, high-strength concrete is poured in the cavities, a strip-shaped grate concrete-filled steel tube combined structure shear wall plate is formed, and the shear wall plate is welded with margin steel columns and margin steel beams. The grate steel tube wall plate and the high strength reinforced concrete columns inside tubes are combined for usage, advantages are complementary, teamwork is achieved, lateral deformation of concrete inside the tubes is restricted by the grate steel tubes, hooped reinforcements of the reinforced concrete columns inside the tubes and the grate steel tubes are welded and tied, so that the bending resistance of the grate steel tube wall plate can be improved. The strip-shaped grate concrete-filled steel tube combined structure shear wall has the advantages that the structural rigidity is high, the construction is quick, the bending resistance is high, the yield load is high, the ductility is good, the energy consumption performance is good, the construction cost is low, and the like. The shear wall can be applied to an ultrahigh steel structure building.

Description

technical field [0001] The invention belongs to the field of building structure engineering, and relates to a composite structure shear wall, in particular to a long grid steel tube concrete composite structure shear wall. Background technique [0002] High-rise steel structure buildings represent the development direction of future building structures. It has comprehensive advantages such as high strength, light weight, low foundation costs, high degree of industrialization, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. With the increase of my country's steel output and the development of real estate construction, high-rise steel structure buildings have been more and more used. my country is an earthquake-prone country. In order to ensure the seismic safety of high-rise steel structure buildings, it is necessary to set up a lateral force-resistant shear wall structure system to resist strong earthquakes. ...

Problems solved by technology

[0004] The existing double-layer steel plate shear wall structure technology has more or less deficiencies and is not mature enough. Some double-layer steel plates adopt simple bolt tie connection measures, and the force of the tension structure is unreliable; The multi-story steel plate shear wall has a complex structure, and it cannot be poured into concrete to form a combined shear wall structure, which cannot bear vertical loads; some corrugated steel plate shear walls with pure steel structures do not have restoring strength after buckling, and their ductility is extremely high.
