Abstract

The invention belongs to the technical field of building structure earthquake resistance, in particular relates to an interlayer collaborative earthquake-resistant wall, and aims to solve the problems of insufficient side stiffness, insufficient material performance and uneven interlayer displacement distribution of the traditional shear wall with an energy consumption damper. The anti-seismic wall comprises an upper wall body and a lower wall body, wherein flexible filling plates are arranged on two sides of the upper wall body and the lower wall body to release lateral constraint, wall connecting pieces are arranged between the wall bodies, and a contact surface is made of friction energy consumption materials. The wall connecting piece consists of a bolt, a spring, a sleeve, a shell, a sliding plate, a stop block and a bolt. When the bolt is triggered in a major earthquake, the upper wall body and the lower wall body are automatically locked when returning to the initial relative positions, and the integral rigidity and the bearing capacity of the wall body are obviously improved. The bearing potential of the device is furthest exerted while the structural function is recovered. The design can realize interlayer collaborative earthquake resistance, optimize interlayer displacement distribution, fully excite the integral earthquake resistance potential of the structure, and improve the local and integral structural failure modes.

Description

Interlayer collaborative anti-seismic wall Technical Field The invention belongs to the technical field of earthquake resistance of building structures, and particularly relates to an interlayer collaborative earthquake-resistant wall. Background The wall body in the building structure is an important lateral force resisting component and has certain energy consumption under the action of earthquake load. The wall body is mainly divided into a shear wall with higher rigidity and a common filling wall. The former assumes most of the interlaminar shear forces in the building, while the latter generally does not take into account its seismic action, only as a safety reserve. The frame structure and the shear wall can form a frame shear wall structure, and the structural system has the advantages of flexible space arrangement of the frame structure and strong shock resistance of the shear wall structure, and is widely applied to the field of engineering construction, in particular to a high-rise building structure. In order to optimize the restorable function capability of the shear wall after earthquake, the shear wall is generally divided into an upper part, a lower part, a left part and a right part, partial restraint of the shear wall is released, and the relative displacement between the walls is utilized to combine various energy-consuming dampers to consume earthquake energy. At the moment, the shear wall has larger bearing capacity, basically is not damaged or only slightly damaged, and the function of the shear wall can be recovered only by replacing the energy consumption damper. Because the partial constraint of the shear wall is released, the whole shear wall is divided into smaller plates, the lateral deformation resistance of the wall is obviously reduced, the contained larger bearing capacity of the wall cannot be fully exerted, and the problem of underutilization of the material performance exists. Under the action of earthquake, deformation is often concentrated on floors with larger horizontal shearing force, such as building floors. When a weak layer occurs, catastrophic weak layer failure is likely to occur, while other floors are substantially intact. At this time, the interlayer displacement angle is unevenly distributed, and the earthquake-resistant potential of the whole structure cannot be fully exerted. In summary, there are unreasonable failure modes in both the local shear wall and the overall structure. Disclosure of Invention In order to solve the problems, the invention aims to provide an interlayer collaborative earthquake-resistant wall, which releases lateral constraint by splitting a wall body and arranging a flexible filling plate, realizes energy consumption and locking functions under different earthquake intensities by means of special wall connecting pieces, not only considers the function restorability during medium and small earthquakes and the bearing capacity during large earthquakes, but also promotes interlayer collaborative work, optimizes internal force and deformation redistribution, thereby improving local and overall structural performance and fully exciting the earthquake-resistant potential of the structure. In order to achieve the above object, the present invention adopts the following technical scheme: The interlayer collaborative earthquake-resistant wall comprises an upper wall body and a lower wall body, wherein flexible filling plates are arranged on two sides of the upper wall body and two sides of the lower wall body, and a wall connecting piece is arranged between the upper wall body and the lower wall body. The earthquake-resistant wall is divided into an upper part and a lower part, friction energy dissipation materials are arranged on the contact surfaces of the upper wall body and the lower wall body, and relative displacement friction energy dissipation is utilized. Side edges of upper and lower walls a flexible filler plate is provided and is positioned, releasing the lateral constraint of the earthquake-resistant wall. The wall body connecting piece comprises two bolts, the top of each bolt is connected with a spring, and each bolt is slidably connected in the first sleeve. The wall connecting piece further comprises a shell, a sliding groove is formed in the shell, two sliding plates are connected in the sliding groove in a sliding mode, the sliding plates are connected with the shell in a sliding mode, the sliding plates are only allowed to slide along the sliding groove and are not allowed to be separated, a stop block is fixedly connected to each sliding plate, a plurality of bolts are connected to the stop block in a threaded mode, and two second sleeves are fixedly connected to the bottom end of the shell. The bolt can pass through the first sleeve and the shell and is connected inside the second sleeve in a sliding way.
