Embodiment 1
[0044] as attached Figure 1-7 Shown, its concrete structure of metal piston damper provided by the present invention is as follows:
[0045] The damper includes a cylindrical inner shaft 1, the inner shaft 1 is made of high-strength steel (Q345 steel plate or other easy-to-process, low-cost high-strength steel), the cross-sectional shape is circular, and a seamless round steel column can be used. There is a notch on the outer periphery of the shaft 1 at the welding place with the annular steel plate 3, and there are no incisions on the rest of the periphery;
[0046] There are two ring-shaped steel plates 3 outside the inner shaft 1, which are the first ring-shaped steel plate 301 and the second ring-shaped steel plate 302. The outer edges of the first ring-shaped steel plate 301 are welded with the upper steel outer tube 2 and the middle steel outer tube 4 respectively; The outer edges of the two annular steel plates 302 are welded to the middle steel outer tube 4 and the l...

Abstract
The invention relates to the field of anti-seismic buildings, in particular to a metal piston damper. The metal piston damper provided by the present invention includes an inner shaft, and there are two steel plates outside the inner shaft, which are respectively the first steel plate and the second steel plate, and the outer edges of the first steel plate are respectively connected with the upper steel outer tube and the middle steel outer tube The outer edge of the second steel plate is respectively connected with the middle steel outer tube and the lower steel outer tube; the inner edge of the first steel plate and the second steel plate are respectively connected with the inner shaft; the first steel plate and the second steel plate are parallel. The beneficial effect of the present invention is that the damper of the present invention adopts the inner shaft in the form of a steel column, which effectively improves the bearing capacity of the damper, reduces the yield deformation of the internal components of the damper, and reduces fracture; and can also realize factory production and welding, Improve work efficiency. In addition, it is easy to manufacture and install, and inexpensive. In addition, the damper of the present invention can be directly installed on the bottom or top of the support without considering the size and installation of the damper.
Description
technical field [0001] The invention relates to the field of anti-seismic buildings, in particular to a metal piston damper. Background technique [0002] In metallic dampers, seismic input energy is dissipated by inelastic deformation of the metal. Metal dampers are widely used in the seismic protection of structures due to their simple, economical and effective energy dissipation mechanism. Traditional filled tube dampers work on the principle that a filled tube device consists of two welded tubes with two smaller tubes inside, and the space between the tubes is filled with metal such as lead or zinc. Filled tube dampers employ shear loading, utilizing the plasticization of the outer tube, inner tube, and filler metal, and metal-to-metal friction as energy absorption mechanisms to dissipate the energy generated by earthquakes. However, compared with other metal dampers, the stiffness and strength of filled tube dampers are lower, which may cause the appearance of weak la...
