Multi-cavity L-shaped encased-steel plate shearing wall

Abstract

The invention relates to a multi-cavity L-shaped encased-steel plate shearing wall. The multi-cavity L-shaped encased-steel plate shearing wall is characterized by comprising a first encased-steel plate, a second encased-steel plate, a middle ribbed plate, an end ribbed plate, concrete, an upper ribbed plate, a lower ribbed plate, holes on corresponding positions of floor beams and for pouring concrete in the upper ribbed plate and the lower ribbed plate and exhaust holes in connection corners of the upper ribbed plate and the lower ribbed plate with the first encased-steel plate, the second encased-steel plate or the end ribbed plate, the first encased-steel plate and the second encased-steel plate are respectively arranged at the outer side of the shearing wall along the length direction of a shearing wall body, the middle ribbed plates satisfying the space requirement are arranged along the length direction of the shearing wall, concrete is poured in a cavity respectively formed among the first encased-steel plate, the second encased-steel plate and the middle ribbed plate to form the multi-cavity L-shaped encased-steel plate shearing wall. The multi-cavity L-shaped encased-steel plate shearing wall has the advantages of the ordinary rectangular reinforced concrete wall body and a built-in steel plate shearing wall, the stretchability of the wall body can be improved, the plastic development under the earthquake or strong wind can be delayed, and the thickness of the wall body is reduced.

Description

technical field [0001] The invention relates to a shear wall structure, in particular to a multi-cavity L-shaped outsourcing steel plate shear wall formed by placing steel plates on the outside of the wall and setting ribs at a certain distance along the length direction of the wall. Concrete belongs to the field of construction engineering. Background technique [0002] Concrete has high compressive strength and a wide range of material sources. The compressive and tensile strengths of steel bars are the same and very large. The shear wall composed of concrete and steel bars can give full play to the material properties of concrete and steel bars, and is widely used in actual projects. Concrete shear walls have high rigidity and high compressive strength, and are one of the indispensable components in high-rise concrete structures. The codes currently issued in my country are "Code for Design of Concrete Structures", "Code for Seismic Design of Buildings", "Concrete Structu...

Problems solved by technology

[0008] The purpose of the present invention is to solve the problem of the traditional pure concrete shear wall under rare earthquakes, where the tensile stress exceeds the limit value of the concrete tensile strength, the plasticity develops too fast, and the premature failure; and the built-in steel plate shear wall has complex structure and high construction difficulty. , High cost and other disadvantages
