Abstract
The utility model relates to a can release lateral restraint's rubber support, this support can be divided into the rubber part of taking the rivet, lower steel sheet and the last steel sheet of taking the recess. When finishing bearing installation, the rivet just in time inlays in the recess of last steel sheet, can reduce the effect that the frictional resistance played the release restraint like this. This support can be used to the medium and small footpath bridge of striding, and the preparation is convenient, low in cost. Can make the bridge atress more reasonable by simple effectual release bridge lateral restraint.
Description
Technical field
This utility model belongs to road and science of bridge building field, relates to a kind of rubber support, particularly relates to one and can discharge laterally
The rubber support of constraint.
Background technology
Along with the fast development of China's transport development cause, highway bridge as a kind of special Highway Structural Material crossing over landform,
Whole transport development is played extremely important effect.Transport power owing to undertaking required for highway bridge is more and more heavier.The width of bridge floor
Spend the most increasing.So would generally place multiple bearing below girder and meet force request.But in same row, general
One bearing with lateral confinement is set.Other bearings then need to discharge lateral confinement, and otherwise two bearings can interact.
When girder because the other reasonses such as shrinkage and creep are when laterally producing displacement with deformation, if multiple bearing is provided which lateral confinement,
So girder can produce the biggest second inner force.The like this discontinuity of bridge, stress is poor.And can discharge
The bridle iron of lateral confinement then cost is the highest, and makes complexity.Rubber support with low cost then needs bigger thickness to produce
Unboiled water is put down to displacement, uses very inconvenient.
Utility model content
Be difficulty with the practical problem of lateral confinement release for current bridge pad, the purpose of this utility model is to provide one can
The rubber support being used on Short/Medium Span Bridge, discharges lateral confinement for girder, makes bridge force-bearing more reasonable.And bearing
Low cost, makes simple, easy to use.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of rubber support that can discharge lateral confinement, including upper steel plate, lower steel plate and rubber, it is characterised in that: described
The rubber support that can discharge lateral confinement also includes being arranged on the rivet of rubber upper surface；Described upper steel plate pass sequentially through rivet with
And rubber is compressed on lower steel plate.
The lower surface of above-mentioned upper steel plate is provided with groove；Described rivet is inlayed in a groove and the most relatively slides.
Above-mentioned rivet is multiple, and multiple rivets are linear or matrix arrangement.
When above-mentioned multiple rivet is arranged in arrays, described groove is a plurality of, a plurality of groove parallel arranged.
The utility model has the advantages that:
This utility model provides a kind of rubber support that can discharge lateral confinement, including upper steel plate, lower steel plate and rubber, with
Time, also include the rivet being arranged on rubber upper surface；Upper steel plate passes sequentially through rivet and rubber is compressed on lower steel plate.This reality
Insert the upper surface of rubber with Novel rivet, fix.Rivet is Tong Bu subjected to displacement and deform with rubber.Meanwhile, at upper steel plate
Lower surface be provided with the groove corresponding with rivet, facilitate rivet to slide to discharge lateral confinement in groove.With existing rubber
Bearing is compared, and this utility model can reduce the frictional resistance between upper steel plate and rubber, steel and rubber contact is become steel and connects with steel
Touching, it is easier to release lateral confinement, and bearing is with low cost, steel using amount is much smaller than die bearing, easy to make, uses letter
Single, it is adaptable to Short/Medium Span Bridge, and bridge force-bearing can be made more reasonable.This bearing can be divided into rubber part and the band of band rivet
The upper steel plate of groove and lower steel plate.

Detailed description of the invention
Seeing Fig. 1, this utility model provides a kind of rubber support that can discharge lateral confinement, and identical with existing bearing is
All including upper steel plate 3, lower steel plate 4 and rubber 5, difference is: this utility model also includes being arranged on rubber 5 upper surface
Rivet 1, be also arranged on the groove 2 of upper steel plate 3 lower surface；Upper steel plate 3 passes sequentially through rivet 1 and rubber 5 is compressed on lower steel
On plate 4.
Seeing Fig. 2 and Fig. 3, the rivet 1 that this utility model is used can be multiple, and multiple rivets 1 are in linear array or in square
Battle array arrangement.
The lower surface seeing Fig. 1 and Fig. 2 upper steel plate 3 is provided with groove 2, groove 2 parallel arranged；Rivet 1 is embedded in groove 2 also
Relatively slide at groove 2.This utility model is provided with the groove corresponding with rivet at the lower surface of upper steel plate, facilitates rivet at groove
Interior slip is to discharge lateral confinement.Compared with existing rubber support, this utility model can reduce between upper steel plate and rubber
Frictional resistance, becomes steel into steel with rubber contact and contacts with steel, it is easier to release lateral confinement,
In conjunction with Fig. 1 to Fig. 2, the upper steel plate 3 fluted 2 of this utility model bearing, rubber upper surface is inserted with rivet 1.Work as upper steel plate
3 when contacting with rubber 5, and steel plate before contacts with rubber support and becomes steel plate and contact with rivet.So frictional resistance of contact surface
Reducing, the constraint to girder is horizontal is just released.And rivet, longitudinally cannot slide along sliding laterally in inside grooves, this
Sample bearing just constrains the length travel of girder.
Seeing Fig. 4, as can be seen from the figure the mutual displacement between girder 6 and pier 7 is realized by bearing.Pier 7 is to master
The effect of contraction of beam is also realized by bearing.
