Description
Technical Field
The invention relates to an anti-buckling steel plate concrete composite wall.
Background
At present, steel structure assembled houses are widely popularized in China, but the assembled steel structure houses have more problems and restrict the development of the assembled steel structure houses. Most residential buildings are high-rise buildings, the structural form generally adopts a steel frame-support structure, the arrangement of supports is extremely limited due to the influence of factors such as door and window openings, and inclined walls generated by the arrangement of inclined supports are extremely difficult in secondary structure construction, so that the progress and the quality of engineering are seriously influenced. To avoid the above problems, steel plate shear walls are generally used instead of struts to resist horizontal forces. However, the traditional steel plate shear wall brings new problems when being applied, the steel plate shear wall is difficult to form good connection with a secondary structure when measures such as fireproof paint or fireproof plates are adopted, and cracks are easy to generate in the later period. Therefore, the invention discloses an anti-buckling steel plate concrete composite wall.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the buckling-restrained steel plate concrete composite wall which has the advantages of standardization, good performance, flexibility, few cracks and wide practicability.
In order to solve the technical problems, the technical scheme of the invention is as follows:
a buckling-restrained steel plate concrete composite wall is characterized in that a vertical seam opening steel plate is fixedly connected between an upper steel beam and a lower steel beam, at least two vertical seams are formed in the vertical direction on the vertical seam opening steel plate, steel bar trusses are fixedly connected between the vertical seams on the surfaces of two sides of the vertical seam opening steel plate in the vertical direction, and buckling-restrained concrete plates are poured on two surfaces of the vertical seam opening steel plate;
through adopting above-mentioned technical scheme, steel sheet and buckling restrained concrete slab's connection can be strengthened to steel bar truss, and buckling restrained concrete slab multiplicable is to the restraint of division perps steel sheet, prevents to open perps steel sheet bucking, improves the anti-seismic performance of division perps steel sheet.
Preferably, the vertical seam steel plate is close to the two ends of the upper steel beam and the lower steel beam, and bolt holes are formed in the two ends of the upper steel beam and the two ends of the lower steel beam.
Preferably, the upper steel beam and the lower steel beam are fixed with the vertical seam steel plate through bolts.
Preferably, the steel plate with the vertical seams is welded with the steel bar truss.
In summary, the invention has the following beneficial technical effects:
1. the buckling-restrained steel plate concrete composite wall can be subjected to standardized design, industrial production is carried out in a prefabricated part factory, and the construction period is shortened.
2. The restraint of the anti-buckling concrete plate can improve the ductility of the steel plate with the vertical seam and enhance the performance of the assembled steel structure under the condition of heavy shock; the buckling-restrained steel plate concrete composite wall is not limited by door and window openings and the like, can be randomly arranged at a solid wall and is more flexible; the concrete outside the steel plate can be used for fire prevention, the problem of cracks at the joint of a common fire-proof coating, a fire-proof plate and a secondary structure is solved, and the concrete has wide practicability.
