Three-dimensional energy-dissipating shock-isolation bearing

Abstract

The invention discloses a three-dimensional energy dissipation and earthquake isolation support seat which comprises a base plate, a top plate, U-shaped strips, a sliding element, a box-shaped component, a support shaft, a disc spring and a U-shaped frame, wherein the base plate and the top plate are in parallel and corresponding arrangement at top and bottom; the two ends of the U-shaped strips are respectively and fixedly connected with the edges of the base plate and the top plate; the plurality of U-shaped strips are uniformly distributed; the sliding element is glidingly attached to the top surface of the base plate, and slides in a horizontal plane in a position limiting way; the box-shaped component is fixed on the top surface of the sliding element; one end of the support shaft isfixed on the top surface of the box-shaped component; the other end of the support shaft penetrates out of the top plate; the disc spring is arranged on the support shaft in a sleeving way; and the U-shaped frame reversely covers the top surface of the top plate. The three-dimensional energy dissipation and earthquake isolation support seat has the advantages that the earthquake isolation and energy dissipation effects are good; the construction is convenient and fast; and the material taking is easy, and the like. The earthquake power effect is isolated in the horizontal free direction; underthe vertical earthquake effect, the earthquake isolation performance is good; certain self resetting capability is realized; the problem that the vertical earthquake waves are seldomly considered inthe earthquake isolation design of the engineering at a current stage can be effectively solved; and high practicability is realized.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption, and more specifically relates to a three-dimensional energy dissipation shock-isolation support. Background technique [0002] At present, the impact of seismic waves on building structures is similar to the effect of exerting a force on the bottom of the structure. This "force" acting on the foundation of the building structure is relatively complex and unstable. According to the characteristics of seismic waves on buildings, the impact on building structures mainly includes horizontal seismic components, vertical seismic components and three rotational seismic components. However, in the isolation design of most building structures, the impact of vertical seismic waves is often not considered. impact on building structures. [0003] Although with the increasing development of science and technology, in order to further improve people's safety and security perfor...
