The support seat has high vibration damping and anti-displacement ability in every horizontal direction.
Description
Technical field
The utility model relates to a kind of vibration damping holder, is a kind of vibration damping holder that is used for bridge or building structure.
Background technology
The existing bearing that is used for bridge or building structure, usually adopt rubber tile to carry out vibration damping, yet this bearing only is to have reduced the impact of vibration to bearing, and the horizontal movement ability that the opposing vibration causes is poor, and aging phenomenon is arranged, and irreversible deterioration takes place in aging its mechanical property of back and damping property.
On May 7th, 2003, disclosed Chinese patent literature CN1415802A disclosed a kind of hyperbolical steel support of inventor's invention, this steel support comprises loam cake, SMIS, base and static housing, base is installed in the static housing, loam cake passes the top case lid of static housing, the elastic vibration clamper that has the particularly arc leaf spring of spring to constitute between loam cake sidewall and static housing.This bearing since between wall box and loam cake sidewall flexible vibration absorber, so have displacement capacity on stronger antivibration and the anti-horizontal direction.But, this bearing is because elastic vibration clamper adopts many group leaf springs, helical spring is fixed on the loam cake sidewall, and casing is square chest, every group of elastic vibration clamper is single direction, the preferred direction of its vibration damping and resist displacement is on the orthogonal both direction of level, it is the installation direction of spring, but because the vibration that earthquake or other modes cause does not have specific direction usually, can not guarantee the elastic force direction basically identical of the total and spring of direction of vibration like this, when the direction of displacement of vibration on the horizontal direction or horizontal direction was in a certain angle between the elastic force direction of two groups of adjacent elastic vibration clampers, its effectiveness in vibration suppression and resist displacement effect just can descend.
The utility model content
The purpose of this utility model is to overcome the deficiency of bearing on horizontal antivibration and resist displacement of prior art, a kind of universal horizontal vibration damping holder that all has strong antivibration and resist displacement ability on any direction of level is provided, and antivibration and the resist displacement ability basically identical of this bearing on all directions of level.
In order to achieve the above object, the universal horizontal vibration damping holder that the utility model provides comprises casing, loam cake, SMIS and a base, base is positioned at casing, SMIS is positioned in the middle of base and the loam cake, it is characterized in that: described casing is cylindric, described loam cake is cylindric, around loam cake and between the box inside wall radial elastic vibration absorber is arranged, and elastic vibration clamper is around loam cake.
Described radial elastic vibration absorber can be for having the corrugated spring circle of axial ripple, and the corrugated spring circle can be one, also can for a plurality of piles together.Described radial elastic vibration absorber can also adopt this type of flexible member to consider the replacing measure simultaneously for cylindric corrugated vibration isolation rubber or the inner cylindric nonmetal damping ring that cellular hole is arranged.
This universal horizontal vibration damping holder that the utility model provides, because loam cake and casing are respectively cylindric and cylindric, the radial elastic vibration absorber is installed in the annular gap of between, the radial elastic vibration absorber is looped around around the loam cake, so when any direction in level produces vibration and displacement, all there is the radial elastic vibration absorber to produce elastic force because of being subjected to oppressing, and elastic force is opposite with direction of vibration or direction of displacement, so its vibration damping and resist displacement ability all are uniformly on all directions of level, therefore on all directions of this bearing ground level stronger vibration damping and resist displacement ability are arranged all.
Description of drawings
Fig. 1 is the structural representation of a kind of universal horizontal vibration damping holder of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments universal horizontal vibration damping holder of the present utility model is described further, to help understanding content of the present utility model.
As shown in Figures 1 and 2, present embodiment is a kind of preferred embodiment of universal horizontal vibration damping holder, in a casing 5 cylindraceous, the rail plate 6 of a circular ring metal plate formation is welded on the inwall of casing 5, base 3 lower limbs are installed in casing 5 bottoms by rail plate 6 and are blocked by guide rail 6 pressures, base 3 can slided, simultaneously because of the restriction of ring-shaped guide rail 6 and can not in casing 5, extract on the horizontal all directions in casing 5.Base 3 has SMIS 2 by tongue-and-groove structure and loam cake 1 interlock between base 3 and loam cake 1.Loam cake 1 is cylindric, be that its horizontal cross sectional geometry is for circular, be placed with the radial elastic vibration absorber that a wavy metal shape turn 4 that has an axial ripple constitutes in the annular space that between the sidewall of the inside wall of casing 5 and loam cake 1, constitutes, corrugated spring circle 4 is looped around around the loam cake 1, as shown in Figure 2, corrugated spring circle 4 maximum outside diameter places withstand on the inwall of casing 5 cylindraceous, and the minimum diameter place withstands on the outer wall of loam cake 1.
Because the radial elastic vibration absorber that has the corrugated spring circle to constitute, and because the elasticity of corrugated spring circle on all directions of level is consistent substantially, so its vibration damping and resist displacement ability on all directions is identical.When because vibration when making on all directions of loam cake 1 relative casing 5 in level the generation displacement, corrugated spring circle 4 is compressed generation elastic force, its elastic force can play vibration damping and reduce the effect of the displacement of vibration generation, and have and make loam cake 1 return to the trend of original position, make bearing on all directions of level, all can produce favorable damping and resist displacement effect.
The whole corrugated spring circle that wavy metal shape turn 4 also can adopt a height and placement space height in the casing to adapt also can pile up together for a plurality of.
The radial elastic vibration absorber also can adopt undulatory vibration isolation rubber annulus, or has the nonmetal damping ring in cellular hole, also can be in the annulus between loam cake and the wall box elastic element of other type of filling.Adopt the metal bellows spring in the present embodiment to compare with other elastic vibration clamper except that having the advantage that modulus of elasticity is big, the resist displacement ability is strong, can resist≤displacement of 500mm, because of there not being problem of aging, so use more the life-span long.
SMIS 2 soffits can be spherical or hyperboloid shape or existing other shape, to adapt to the requirement that discharges torque on the different directions.
