Description
Technical field
The utility model belongs to Highway bridge technique field, relates to shock mount device.
Background technology
At present, personnel's aseismatic bearing that domestic bridge adopts mainly contains high-damp rubber support, shear-pin shock isolating pedestal and friction pendulum aseismatic bearing, and performance and feature that it is main are as follows:
The shortcomings such as 1, " high-damp rubber support " can utilize the damping characteristic of rubber that earthquake resistance is provided when support displacement, reduce and absorb seismic load, but the bearing capacity of high-damp rubber support is less, and rubber is easily aging, and earthquake displacement is little and inflammable.
2, existing " shear-pin shock isolating pedestal " when earthquake, while can only Earthquake occurrence control reaching susceptor design seismic load, shear-pin release, isolation seismic load, reaches the object of protection bridge pier.
3, existing " friction pendulum aseismatic bearing " adopts two sphere displacements, logical two spheres rotate to realize antidetonation mutually, during bearing normal displacement, just can provide frictional resistance, owing to can causing the lifting of beam body after two spherical rotation, can affect bridge overall force structure, particularly cable stayed bridge and suspension bridge, simultaneously because two spherical radius are very large, seat structure size is large, and cost is very high.
Utility model content
The purpose of this utility model is: a kind of shock-absorbing function of realizing in earthquake displacement process is provided, does not affect again the shock mount of the force structure of bridge simultaneously.
The purpose of this utility model realizes by following technical proposals:
A kind of elastic ring shock mount device, comprise a seat body, it comprises upper bracket and undersetting, also comprises elasticity loop chain, described elasticity loop chain is an elastic ring or is interlocked and formed by a plurality of elastic ring series windings, is connected with at least one elasticity loop chain between described upper bracket and undersetting.
As selecting 1, described elasticity loop chain is divided into some levels by length difference, and elastic ring chain length at the same level is identical, is connected with at least 2 grades of elasticity loop chains between described upper bracket and undersetting.
As selecting 2, the elastic ring chain length between described upper bracket and undersetting is identical.
As selecting 3, described elastic ring is annulus, elliptical ring or Fang Huan.
As selecting 4, described elasticity loop chain outer wrap has rubber layer.
As selecting 5, the Connection Block of described elasticity loop chain by two ends and described upper bracket and undersetting are connected and fixed.
As selecting 6, described seat body also comprises corrosion resistant plate, wearing plate I, middle steel plate, wearing plate II, is provided with successively from top to bottom described corrosion resistant plate, wearing plate I, middle steel plate and wearing plate II between described upper bracket and undersetting.
The main scheme of aforementioned the utility model and each further selection scheme thereof can independent assortment to form a plurality of schemes; be the utility model and can adopt also claimed scheme: as the utility model; each select can and main scheme and other select (wherein select 1 or 2 select a selection) any combination; those skilled in the art can understand there is multiple combination according to prior art and common practise after understanding the present invention program, at this, do not do exhaustive.
The course of work of the present utility model: as select 6 examples, this patent structure applications is in spherical bearing, this patent structure can be used as the functional part of existing various bearings, as spherical bearing, pot bearing and laminated rubber bearing etc., makes common bearing have the performance of aseismatic bearing.Being connected between bearing (upper bracket and undersetting) and bridge beam body and pier adopts welding manner or bolt connecting mode, can select according to design and construction requirement.This patent adopts elastic ring, and each elastic ring radially has certain elasticity, and each elastic ring series winding interlocks, and when elasticity loop chain under tension, each elastic ring produces radial deformation, and elasticity loop chain has larger stretcher strain amount.Elasticity loop chain one end and upper bracket are fixed, and the other end and undersetting are fixed.When beam displacement body, elasticity loop chain is with upper bracket and the displacement of beam body, and elastic ring is subject to radial pull, and elastic deformation occurs, and bearing is held downwards, with beam displacement body, strengthens, and elastic ring distortion is increasing, and the pulling force providing is also larger.The elastic ring diameter, elastic ring thickness, quantity and the length that change elasticity loop chain are carried out the pulling force size of adjustable elastic loop chain, the damping force size that elasticity loop chain provides to beam body.Each bearing can arrange the elasticity loop chain of different length, by length difference, is divided into some levels, and by length from be short to dash be divided into one, two, three so that N(N be positive integer) level.Such as elasticity loop chain divides two-stage even more than 3 grades, controlling respectively the different displaced position sections of beam body moves, normal displacement section at bearing, first order elasticity loop chain tension, the pulling force that elasticity loop chain provides is little, when support displacement arrives near maximum displacement, second level elasticity loop chain starts to be subject to, and the larger pulling force that elasticity loop chain provides is large.While surpassing bearing normal displacement, third level elasticity loop chain can be set, strengthen draw ring pulling force, also can destroy the shorter elasticity loop chain of the first order and consume seismic forces simultaneously.
The beneficial effects of the utility model:
1,, during support displacement, elasticity loop chain tension power, hinders beam displacement body, at the whole displacement process continuous consumption seismic forces of beam body, reaches the object of damping.
2, adopt classification earthquake resistant structure, the length of elasticity loop chain can be divided multistage, realizes beam body in displacement hour, and elasticity loop chain provides damping force little, and when displacement is larger, the damping force that elasticity loop chain provides is large.
3, elasticity loop chain is function of seismic resistance parts, can combine with the bearing of any type, forms corresponding aseismatic bearing.
4, elasticity loop chain is connected with lower support plate with upper bracket plate by Connection Block, and former seat structure be there is no to impact.
5, elastic ring chain structure is simple, and cost of production is low.
