Abstract

The utility model relates to a concealed bracing energy-intensive low shear wall structure system with built-in steel plates and steel bars. The system comprises border pillars, inside casing pillars, section steel inside casing pillars, steel bar meshes consisting of horizontal steel bars and vertical steel bars between the border pillars and the inside casing pillars, and a steel bar mesh consisting of horizontal steel bars and vertical steel bars between the section steel inside casing pillars, and is characterized in that a shear wall structure is divided into three parts, slant concealed braces are arranged between the border pillars and the inside casing pillars at two sides, a shear resisting steel plate with shear resisting steel bars is arranged between the section steel inside casing pillars in the middle part, two edges of the shear resisting steel plate are respectively welded with section steels in the section steel inside casing pillars, the horizontal steel bars in the steel bar meshes are disconnected between the inside casing pillars and the section steel inside casing pillars to form plain concrete seams, and the shear wall is integrally formed by pouring polymer concrete. The system disclosed by the utility model has high bearing capacity and good ductility, is stressed reasonably, and can achieve an ideal failure mode under the effect of large earthquake, so that a large amount of earthquake energy is consumed, the earthquake resistant performance is good, and earthquake disasters can be greatly relieved, and collapse is prevented.

Description

Built-in steel plate-reinforcing bar secretly supports the low shear wall structure system of power consumption

Technical field

The utility model belongs to field of civil engineering, is specially low shear wall structure system category commonly used in the building.

Background technology

The key of antidetonation mitigation is to strengthen the shock resistance of building.Reinforced concrete shear wall is the core antidetonation parts of building structure.Low shear wall refers generally to ratio of shear span to effective depth of section less than 1 shear wall, is usually used in multi-layer bottom frame structure and high-rise Large Space at Lower Part structure.Common low shear wall is made up of frame columns and common armored concrete wallboard, under horizontal loads, shear brittleness takes place destroy.The existing method of improving low shear wall performance mainly concentrates on the following aspects: perps is set in shear wall, though this method has bigger effect to the ductility that improves member, has reduced the rigidity and the bearing capacity of member to a great extent; In the newel post of shear wall, add shaped steel, though can under the situation that guarantees bearing capacity, improve the ductility of member preferably, member later stage rigidity and bearing capacity reduce bigger, and do not change the failure mode of low shear wall, still belong to brittle fracture.Adopt existing low shear wall anti-seismic performance of improving one's methods still undesirable.

The utility model content

The purpose of the utility model provides a kind of built-in steel plate-reinforcing bar and secretly supports the low shear wall structure of power consumption, is issued to desirable failure mode to realize low shear wall in geological process.

The technical scheme of the utility model: comprise frame columns, inside casing post, shaped steel inside casing post, be located between frame columns and the inside casing post and the steel mesh reinforcement that constitutes by horizontal reinforcement and vertical reinforcing bar between the shaped steel inside casing post; It is characterized in that; Shear wall structure is divided into three parts, is provided with oblique dark support between the frame columns of its both sides part and the inside casing post, is provided with the anti-shear steel plate of band shear reinforcement between the shaped steel inside casing post of intermediate portion; The both sides of anti-shear steel plate respectively with shaped steel inside casing post in shaped steel weld mutually; Horizontal reinforcement breaks off between inside casing post and shaped steel inside casing post in the steel mesh reinforcement, formin concrete seam, and shear wall integral body is built by polymer concrete.

Said shear reinforcement is scattered in equally spaced many rows form on anti-shear steel plate.

Said shaped steel is I font steel.

The utility model adds the shear resistance that built-in steel plate can significantly improve shear wall; Adding built-in oblique dark support can prevent the too early cracking of both sides shear wall and can improve ductility.The employing polymer concrete is built, and can improve the damping of structure, reduces earthquake response.The utility model is compared with common low shear wall, has the bearing capacity height, and ductility is good; Reasonable stress, and have less thickness and weight, and can make structure be issued to desirable failure mode in big shake effect; Thereby consume a large amount of seismic energies; Have good anti-seismic performance, thereby earthquake disaster mitigation greatly prevents to collapse.
