Viscous damping wall

Abstract

The invention discloses a viscous damping wall, and relates to the technical field of building structure vibration reduction and earthquake proofing. The viscous damping wall comprises a lower container, an inner inserting plate and butting components, wherein the lower container comprises two wall plates in parallel arrangement at intervals; the two wall plates are connected at two sides throughside walls; an accommodating cavity is formed between the two wall plates; a viscous material is accommodated in the accommodating cavity. An inner inserting plate is arranged in the accommodating cavity and is parallel to the wall plates; the inner inserting plate and the two wall plates are in arrangement at equal intervals; stiffening ribs are arranged on the inner inserting plate. Meanwhile, the butting components are arranged on two side surfaces of the inner inserting plate; the butting components are glidingly abutted against the wall plates. The viscous damping wall has the advantagesthat the surface outer rigidity of the inner inserting plate of the damping wall can be improved; the energy dissipation efficiency of the viscous material is improved; the manufacturing and installing work is simplified.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and anti-seismic technology of building structures, in particular to a viscous damping wall. Background technique [0002] With the development of my country's economy and society, a large number of high-rise building structures have been built in major cities in my country to meet the needs of commercial and residential buildings. In order to ensure the safety of the structure, on the one hand, the code restricts the rigidity of the structure. For example, the "Technical Regulations for Concrete Structures of High-Rise Buildings" stipulates the limit value of interstory displacement of different types of high-rise building structures. On the other hand, some non-load-bearing components of structures (such as supports, shear walls, connectors, etc.) , node) with a damping device installed. When an earthquake occurs, as the lateral deformation of the structure increases, the energy-di...

Problems solved by technology

However, this patent has the following two disadvantages: ① The structure of the damping wall is complicated, and the bolt holes are opened on the inner plate, and the viscous material can only be injected from the bottom after the wall is assembled. The viscosity of the material is high, and the whole filling process is still very troublesome

②The inner insert plate is not strengthened laterally, so when the damping wall is working, the inner insert plate may have a large out-of-plane deformation, the damping coefficient is unstable and affects the service life of the damping wall

However, there are technical shortcomings in this patent: the distance between the two sides of the folded plate type interposer and the container wall is different, resulting in different viscous shear rates of the damping materials on both sides of the interposer, and the damping energy consumption efficiency of the viscous material is not high.
