Abstract

The inventive damper consists of upper and lower supporting seats, a boot sleeve, a strength-bearing shock isolating and absorbing layer, a pressure-bearing shock isolating and absorbing layer, a horizontal shock isolating and absorbing layer and a prepressing high-strength bolt. The upper supporting seat is put in the boot sleeve structure with the shock isolating and absorbing layer in each direction to isolate and absorb the shock action in each direction effectively.

Description

Boot-type shock-absorbing damper

Affiliated technical field: engineering structure

Background technique:

Be used to the engineering structure field a lot of years every damping and energy-dissipating and shock-absorbing technology, the development of damper has also obtained very much progress, developed the damper of various ways, the application in engineering structure for standard and promotion every damping and energy-dissipating and shock-absorbing technology, country has also made relevant regulation in " Code for seismic design of buildings ", but promote every the large size that damping and energy-dissipating and shock-absorbing technology do not obtain truly, deficiency on the people that trace it to its cause are familiar with also has the shortcoming of damper self.As: " shock insulation layer neoprene bearing tensile stress should not occur to regulation under the effect of rarely occurred earthquake in country's " Code for seismic design of buildings "."; because existing shock insulation layer neoprene bearing (damper) can not resist tensile stress; do not possess every shock-absorbing function in the displacement process that superstructure makes progress simultaneously, this has greatly limited every the application of cushion technique on the bigger equipment support of high-level structure and up-throwing force.

Summary of the invention:

The present invention by boots formula structural design provide a kind of can draw, under the pressure stress effectively every damping, again can be under horizontal shear every the damper of damping.This damper structure form is shown in Figure of description 1, by upper bracket, undersetting, boots cover, bear every buffer layer, pressure-bearing and form every buffer layer and precompressed high-strength bolt every buffer layer, level.Wherein: upper bracket top is used to connect superstructure, and the bottom then is positioned in buffer layer; Undersetting is used for and being connected of substructure, and forms the precompressed mechanism every buffer layer with Boot sleeve structure and high-strength bolt simultaneously; The boots cover is mainly used in applying precompression every buffer layer, assurance bears, pressure-bearing all can effectively be worked every buffer layer, can limit simultaneously the displacement of upper bracket within the specific limits, its form can also can be polygonal for circle, be divided into the assembling of two-part or many parts for easy to assembly, as shown in Figure 2; The precompressed high-strength bolt is used for applying precompression every buffer layer, and the precompression size is calculated by bearing load and vibrations and determined, the relative displacement S by high-strength bolt moment of torsion or boots cover and undersetting realizes accurately control; Bear every buffer layer and form at interval every vibration-absorptive material and steel plate, when the damper tension, rise every cushioning effect by multilayer; Pressure-bearing also is made up of every vibration-absorptive material and steel plate multilayer at interval every buffer layer, rises every cushioning effect when the damper pressurized; Level is affixed on boots covers inwall every buffer layer, be used for substantially horizontal every damping, bear simultaneously, pressure-bearing, also can play every the effect that subtracts the certain level vibrations owing in the horizontal direction certain displacement can be arranged every buffer layer.This damper is positioned over all directions with upper bracket all to be had among the Boot sleeve structure of buffer layer, thereby can be every the shock effect that subtracts all directions.

Its advantage is specific as follows: 1. this structural type damper can be every the vibrations that subtract all directions, and effectiveness in vibration suppression is than general damping device better effects if.2. this structural type damper using scope is extensive, can be used for many, tall building every damping, also can be used for rack bearing, roof truss bearing, bridge pad, equipment support, also can be used for support, tie-rod of energy-dissipating and shock-absorbing etc.3. this structural type damper structure is simple, easy to make, easy care.
