Abstract
The utility model discloses an assembled metal bending yield damper, comprising: the connecting screw comprises an X-shaped steel plate, a steel cushion block, a connecting nut and a connecting screw. The steel cushion blocks and the X-shaped steel plates are alternately arranged, and the steel cushion blocks and the X-shaped steel plates are assembled into an integral steel cushion block through pre-tightening screw rods to form vertical bolt holes so that the damper is bolted with the structure. Under the action of horizontal earthquake, the upper end and the lower end of the damper generate relative displacement, and the X-shaped steel plate is bent and deformed to provide rigidity and damping for the structure. Compared with the common metal bending damper, the utility model does not need a welding process, avoids the adverse factors of residual stress, process difference, easy fracture of welding parts and the like generated in the welding process, and thus improves the stability of the mechanical property of the damper; in addition, if the X-shaped steel plate needs to be replaced after earthquake, the assembly type connection mode adopted by the utility model can effectively improve the replacement efficiency.

The traditional building earthquake-resistant method is single, the earthquake input energy is dissipated only through the inelastic deformation of the middle beams and the columns of the structure, the application range is wide, but the structure is greatly damaged, and the vibration energy is dissipated by arranging the dampers at certain positions of the building structure, so that the method is a more reasonable and effective method.
Currently, various dampers are available, mainly metal, friction, viscoelasticity and viscous dampers. The common steel plate damper has the advantages of large plastic deformation, good durability, full hysteresis curve, stable performance and the like, but the energy consumption steel plates in the traditional bending steel plate damper are welded with the upper and lower layers of steel plates, and the residual stress and the process difference generated by welding seams in a welding connection mode and adverse factors such as easy breakage of welding parts directly influence the stability of the mechanical properties of the damper, so that the performance deviation of the energy consumption device is larger. In the earthquake, the steel plate in the damper can generate larger shaping deformation, the energy-consuming elements after the earthquake need to be replaced, and the welding connection mode is not easy to replace the energy-consuming elements. In order to solve the problems, an assembled metal bending yield damper is provided, wherein the damper is assembled in an assembled mode, an X-shaped steel plate is used as an energy dissipation element, residual stress and process difference generated by welding can be avoided, and the energy dissipation element is easy to replace after earthquake.
