Abstract
The utility model provides a kind of highway bridge bearing, including upper bracket plate, cochain joint chair, support body, lower chain joint chair, lower support plate, bolt；Support plate is rectangle, and bearing chain joint chair is circular ring shape, and support body is metal rubber material（By austenitic stainless steel wires spring volume, stretching, in a mold braiding, stamping forming material are made through wrapping wire）.Common bearing is laminated rubber bearing on bridge at present, but there are the endurance issues such as serious aging for laminated rubber bearing.The beneficial effects of the utility model are：The aging of rubber bearing can be solved using metal rubber material substitution rubber, the endurance issues such as creep, bearing provided by the utility model can also high- and low-temperature resistance, and can be reached by the good damping characteristic of support body and subtracted, the effect of shock insulation.
Description
Technical field
It the utility model is related to a kind of bridge pad, more particularly to a kind of highway bridge bearing.
Background technology
Bridge pad is the force transferring part of bridge, and the dead load of bridge superstructure and mobile load can be reliably transmitted to pier by it
Platform, and the horizontal distortion that girder produces under temperature change, creep and shrinkage of concrete and mobile load Braking is suitable for,
Common bearing is laminated rubber bearing in highway bridge at present, but can be found that board-like rubber branch from current finding
Seat problem during using use occurs frequently, and such as seat empty, detrusion transfinite, ageing of rubber, rubber surface cracking are asked
Topic, these problems can cause bridge structure stress to change, seriously affect traffic safety, it is therefore desirable to invent a kind of bearing to replace
Laminated rubber bearing.
The content of the invention
The purpose of this utility model is to provide a kind of highway bridge bearing, has the normal use work(of traditional rubber bearing
Can, it can effectively transmit the dead weight of bridge superstructure and spanning mobile load and meet beam-ends corner caused by vertical load, can
Adapt to the horizontal distortion that girder produces under temperature change, creep and shrinkage of concrete and mobile load Braking；And bearing
Ageing-resistant performance, isolation property, service life, bearing capacity etc. are superior to existing laminated rubber bearing.
To achieve the above object, the utility model designs a kind of highway bridge bearing, including support body, upper bracket plate,
Lower support plate, cochain joint chair, lower chain joint chair, bolt.
The metal rubber material that the support body uses be austenitic stainless steel wires through wrapping wire make spring volume, stretching,
Weave, is stamping forming in a mold, this material is made of stainless steel wire, its corrosion resistance and good, ageing-resistant, resistance to high and low
Temperature, service life are far above traditional laminated rubber bearing, and the friction between stainless steel wire and the plastic deformation of stainless steel wire
Can make bearing that there is higher damping under geological process, thus this bearing also have it is good subtract, shock insulation function.
The nominal relative density of the metal rubber material, the i.e. density ratio of Sample density and wire 0.24~
Between 0.40, can by adjusting the nominal relative density of support body come change the rigidity of bearing so as to change the subtracting of bearing,
Isolation property.
The support body is cylindrical type, this is because for large scale metal-rubber component, cylindrical type mould is more
Easily make, and cylinder type metal rubber test piece uniform force during compressing, its end properties are preferable.
The support body is single layer structure, this is because for large scale metal-rubber component, single layer structure adds
Work is easy, mechanical property is more stable.
The highway bridge bearing, its feature are being linked with the upper bracket plate with cochain seat board by welding, undersetting
Plate is linked with lower chain seat board by welding.
The highway bridge bearing, it is characterised in that the upper bracket plate is rectangle, and cochain joint chair is annulus, lower support plate
It is rectangle, lower chain joint chair is annulus.
The highway bridge bearing, it is characterised in that the upper bracket plate, cochain joint chair, lower support plate, lower chain joint chair are all
It is made of steel, and its surface all carries out brush paint after zinc-plated processing.
The highway bridge bearing, it is characterised in that the support body is located between cochain joint chair and lower chain joint chair, on
Support plate is linked by bolt and beam bottom, and lower support plate is linked by bolt and pier.
Brief description of the drawings
1 bearing three-dimensional model diagram of attached drawing
2 bearing main view profile of attached drawing
3 bearing top view of attached drawing
Have in figure：Upper bracket plate 1, support body 2, lower support plate 3, bolt 4, cochain joint chair 12, lower chain joint chair 32.
Embodiment
Below in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
As shown in Fig. 1 to Fig. 3, a kind of highway bridge bearing of the utility model, including upper bracket plate, support body
And lower support plate.Upper bracket plate lower part is provided with cochain joint chair, and cochain joint chair is linked with upper bracket plate by welding, upper bracket plate
Four link holes are set, and upper link hole is linked by bolt and girder；Lower support plate top is provided with lower chain joint chair, lower chain joint chair
Linked with lower support plate by welding, lower support plate sets four link holes, and lower support plate is linked by bolt and pier；Bearing
Body is the single layer structure of cylindrical type, and used material is metal-rubber（Stainless steel wire through wrapping wire make spring volume, stretching,
Braiding, in a mold stamping forming material）, used metal-rubber name relative density is between 0.24~0.4, metal
Elastomeric material is made of stainless steel wire, its corrosion resistance and good, high-low temperature resistant, ageing-resistant, and service life is far above traditional plate
Formula rubber support, and friction between stainless steel wire and the plastic deformation of stainless steel wire can make bearing in geological process to bearing
Lower to have higher damping, this highway bridge bearing also subtracts shock insulation function with good.
It is using beneficial effect caused by above-mentioned technical proposal：
The support body of the utility model employs single-layer metal rubber, single-layer metal rubber structure can with one-pass molding,
Mechanical property is more stable, and metal rubber material is made of stainless steel wire, and corrosion-resistant, high-low temperature resistant, ageing-resistant performance are good, and props up
Seat board and chain joint chair the brush paint all after zinc-plated are handled, its rustless property is superior to ordinary steel support plate, under geological process
Bearing can also be given to provide damping force by the friction between wire and the plastic deformation of wire, thus can reach and subtract, every
The purpose of shake.
