Problems solved by technology

Because in the case of small earthquakes, the plastic energy dissipation characteristics of E-shaped steel cannot be fully utilized, and even in the elastic stage, the energy dissipation effect is not good.
The combination of E-shaped steel and the support requires a certain amount of installation space, so it is not suitable for limited space

Abstract

The invention discloses a novel composite damping shock-absorbing supporting seat. The supporting seat sequentially comprises an upper supporting seat plate assembly, a supporting seat rotary dampingring, a spherical crown body and a lower supporting seat plate, the supporting seat rotary damping ring is arranged between the upper supporting seat plate assembly and the lower supporting seat plate, the spherical crown body is arranged in a tub cavity of the lower supporting seat plate, the spherical crown body comprises an upper protruded spherical body and a lower protruded spherical body which are integrally shaped through an austempering ductile casting technology, the spherical crown body formed by the upper and lower protruded spherical bodies is mushroom-shaped, the tub cavity of thelower supporting seat plate is concave-spherical-shape, the upper protruded spherical body of the spherical crown body is spherically hinged to a concave spherical groove formed in a bottom piston ofthe upper supporting seat plate assembly, and the lower protruded spherical body of the spherical crown body is in tangent contact with the bottom wall of the tub cavity of the lower supporting seatplate. The novel composite damping shock-absorbing supporting seat has the advantages that the weight is light, the restoring capability is high, the service life is long, and different using conditions of non-earthquake, low-level earthquake and high-level earthquake can be taken in consideration.

Description

technical field [0001] The invention relates to the technical field of bridge supports, in particular to a novel composite damping and shock absorbing support. Background technique [0002] Earthquake is a sudden natural disaster that seriously threatens the safety of human life and property. Bridge bearing is a key component that undertakes the upper and lower structures of bridges. The concept of seismic isolation technology was proposed in the 1960s. The seismic isolation of bridges is mainly to provide the necessary vertical support for the upper structure through the seismic isolation bearing and provide flexible buffering in the horizontal direction, so that the horizontal vibration of the upper structure It is separated from the lower structure, thereby prolonging the period of the structure and reducing the transmission of seismic energy to the upper structure; by increasing the damping of the seismic isolation device, absorbing part of the seismic energy to control ...
