Problems solved by technology
[0003] The applicant found that there are at least the following technical problems in the existing various energy dissipation and shock absorption technology products: 1. In the past, the energy dissipation module of the damper was single, and the core components were generally made of a single damping material. For example, the friction damper only used The frictional resistance energy consumption of friction material products, the metal yield damper utilizes the yield energy dissipation of metal materials, and the viscoelastic damper utilizes the nonlinear shear hysteretic deformation of viscoelastic materials to dissipate energy, etc.; 2. In the past, various damping Composite dampers with a combination of materials such as steel-lead extrusion dampers and lead viscoelastic dampers also have certain disadvantages, such as steel-lead extrusion dampers, the connection and assembly of lead cores and steel components is difficult, and lead stick The elastic damper needs to be vulcanized at high temperature and the viscoelastic material needs to be high-damping rubber, which has the disadvantages of complex processing technology and high production cost, and cannot realize modular assembly, which is not conducive to large-scale production
[0005] 1. Under the action of earthquakes in high-intensity areas, when the reinforced concrete coupling beams as energy-dissipating components are subjected to a large force, their shear-compression ratio is often difficult to meet the requirements of the code, and effective energy dissipation cannot be guaranteed, and the concrete coupling beams cannot be repaired after the earthquake ;
[0006] 2. Other types of coupling beam dampers have obvious super strength after yielding, and the ultimate bearing capacity is much greater than the yielding force, which will increase the difficulty of designing surrounding connecting components;
[0007] 3. At present, the embedded parts of all kinds of coupling beam dampers basically adopt the method of welding anchor bars and welded section steel. The construction and installation are extremely difficult, and their installation often has a great impact on the overall construction progress.

The invention discloses an assembly type metal composite damper. The assembly type metal composite damper comprises a first connecting plate and a second connecting plate, wherein the first connecting plate and the second connecting plate are parallel to each other and are vertically arranged, at least one shearing plate is arranged on the side, facing the first connecting plate, of the second connecting plate, a plurality of constraint steel plates are arranged on the first connecting plate and correspond to the shearing plates, the shearing plates are arranged between every two adjacent constraint steel plates, the shearing plates are connected with the corresponding constraint steel plates through a plurality of pre-tightening bolts, and shearing energy dissipation modules and friction core plates are arranged between the shearing plates and the constraint steel plates. The assembly type metal composite damper has the beneficial effects that the energy dissipation capacity of the damper can be remarkably improved, and installation and fixation are convenient; and the shearing plates and the constraint steel plates are connected by adopting the pre-tightening bolts in cooperation with elastic pieces, stable connecting force can be provided in the relative sliding process of the shearing plates and the constraint steel plates, and therefore the shearing plates and the constraint steel plates can carry out friction energy dissipation through stable contact friction force.
Description
technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption of building structures, in particular to an assembled metal composite damper. Background technique [0002] Energy dissipation and shock absorption technology is to install energy-consuming shock-absorbing devices on the key parts of the building structure. By adjusting or changing the dynamic characteristics of the structure to control the response of the structure under the action of the earthquake, the energy dissipation and shock absorption can greatly reduce the impact of the earthquake on the building structure. The role of comprehensively improve the seismic performance of building structures. In recent years, with the extensive application of energy dissipation and shock absorption technology, various types of building structures also have corresponding applicability shock absorber products. Since the core of energy dissipation and shock absorption technolo...
