A steel damping energy-dissipating spherical steel support

Abstract

The invention provides a steel damping energy-consuming type spherical steel support applicable to bridge and building structures. The steel damping energy-consuming type spherical steel support comprises an anchor bar, an upper seat plate, a stainless steel plate, a plane wear-resistant plate, a spherical crown lining plate, a spherical wear-resistant plate, a lower seat plate, a lower seat plate flange, an upper seat plate flange and a steel damping element; the upper seat plate flange is fixedly connected with the upper seat plate and protrudes downward to be in clearance fit with the lower seat plate; the lower seat plate flange is arranged on the periphery or the two sides of the lower seat plate; the steel damping element is connected between the lower seat plate flange and the upper seat plate flange; the upper end of the upper seat plate flange is wide; the lower end of the upper seat plate flange is narrow; the upper seat plate flange has an inverted trapezoidal section; and the inner edge line of the inverted trapezoidal section can be a straight line or an arc line. According to the steel damping energy-consuming type spherical steel support, except that normal use situations of bridges or buildings can be met, seismic energy can be dissipated when the seismic displacement of the support is large, the support can be effectively protected against being destroyed and falling off, and the structural safeties of the bridges or the buildings are protected. The steel damping energy-consuming type spherical steel support has the advantages of simple structure, simple and convenient mounting and easy maintenance and changing.

Description

technical field [0001] The invention relates to the field of bridges and building bearings, in particular to a spherical bearing with energy dissipation function. Background technique [0002] Spherical steel bearing is one of the important components in bridges and construction projects. Its function is to transfer various loads on the upper part of bridges and building structures to the piers through spherical steel bearings, and at the same time ensure the required bearing capacity of bridges and building structures. Force, displacement and rotation requirements. [0003] The traditional spherical steel bearing only has the functions of bearing pressure, displacement and rotation, but has no energy dissipation effect. When the earthquake produces a large horizontal force, the bearing body will be damaged and cause its function to fail, resulting in damage to the bridge structure. endanger people's lives and property safety. On the other hand, in recent years, with the c...

Problems solved by technology

The existing technology mainly uses rubber or friction pairs to buffer and dissipate energy. For example, the patented spherical bearing with energy-dissipating friction pair (CN201581517U) and the shock-resistant damping spherical bearing (CN2705494Y), which are named as energy-dissipating friction pair. Spherical support (public number: CN201581517U), the support has multiple friction pairs, the friction coefficient of each friction pair is very small, it is difficult to ensure that the energy-consuming friction pair can fully play its role; high-damping rubber is easily affected by the environment, resulting in its performance drops

The name is the anti-seismic damping spherical bearing (public number is CN2705494Y). Only high-damping rubber is used to dissipate energy due to extrusion, and the energy dissipation effect needs to be verified.
