Latticed lead extrusion damper

Abstract

The invention provides a latticed lead extrusion damper, which comprises an outer tube, end plate reinforcing plates, end plates, a movable shaft, a fixed shaft, connecting lugs, lead extrusion ports, lead, sealing rings, a movable shaft guide pipe, limiting supports, limiting baffles, a lattice frame, longitudinal lattice plates and transverse lattice plates, wherein the end plate reinforcing plates and the end plates are arranged at the two ends of the outer tube, the sealing rings and the limiting supports are arranged at the two internal ends of the outer tube, the movable shaft is arranged on one internal side and the fixed shaft is arranged on the other internal side and is connected with the end plate; and the lattice frame is arranged between the movable shaft and the outer tube, a plurality of lead extrusion ports are arranged at the middle part of the movable shaft and correspond to transversely cut areas of the lattice frame one to one, and the limiting baffles are respectively arranged on the external sides of the lead extrusion ports (7). The latticed lead extrusion damper has the effects and the advantages that the material utilization ratio is high and the energy consumption effect is good; and the latticed lead extrusion damper is simple to fabricate and install, is convenient to use, and not only can be used for seismic design of newly constructed building engineering, but also can be used for reinforcement and repair of the existing engineering.

Description

technical field [0001] The invention relates to a building structure vibration control device, in particular to a lattice type lead extrusion damper for building structure vibration control. Background technique [0002] Metallic yielding dampers are various forms of damping energy dissipators made of mild steel or other soft metal materials. Metals have good hysteretic properties after yielding, and the elastic-plastic hysteretic deformation energy dissipation of some metals is used. Metal yield dampers include mild steel dampers, lead dampers, and shape memory alloys (SMA) dampers. The mechanism of its vibration control on the structure is to dissipate part of the energy of the structural vibration through the yield hysteresis energy dissipation of the metal, so as to achieve the purpose of reducing the structural response. [0003] Lead dampers make full use of the characteristics of lead, such as high density, low melting point, high plasticity, low strength, strong co...
