Abstract
The utility model is specially a kind of anti-device that comes to nothing of laminated rubber bearing, solves the problems, such as to exist easily to come to nothing when existing laminated rubber bearing earthquake to cause bridge top and the bottom Structural defect.A kind of anti-device that comes to nothing of laminated rubber bearing, including the laminated rubber bearing being arranged between bridge main beam and concrete bent cap, it is cased with the round steel ring being supported on concrete bent cap upper surface outside laminated rubber bearing, the bottom end of round steel ring is provided with circular steel plate, and circular steel plate lower end is provided with the vertical anchor bar being inserted into concrete bent cap.It is reliable that the structure design of the utility model is reasonable, prevent laminated rubber bearing to come to nothing the generation of phenomenon, and then solves the problems, such as bridge top and the bottom Structural defect, and plays the role of the laminated rubber bearing when earthquake occurs and play shock insulation by sliding a part of seismic energy of consumption with bridge main beam, the safety that ensure that bridge structure has the advantages that simple in structure, easy to process and at low cost.
Description
Technical field
The utility model is related to the anti-device that comes to nothing of Highway Municipal bridge, the anti-dresses that comes to nothing of specially a kind of laminated rubber bearing
It sets.
Background technology
Earthquake is that have great destruction for bridge.The performance of bearing can largely reduce earthquake to bridge
Damage effect.Laminated rubber bearing is in highway in China bridge using very extensive.Due to laminated rubber bearing and bridge master
There is no effectively connections for beam, can opposite sliding between bearing and bridge main beam when geological process occurs.This slide effect can
Largely to discharge a part of geological process power, to protecting the safety of bridge substructure that there is good effect.It is board-like
Rubber support slides, and later period maintenance is also very convenient.
In previous Bridge Design, laminated rubber bearing is only located on pinner or on concrete bent cap, not
The effectively sliding range of limitation laminated rubber bearing, in turn results in when earthquake occurs, laminated rubber bearing slid
Greatly, other than the support range for skidding off bridge main beam, bridge main beam is caused to come to nothing, and then bridge main beam is directly pounded in concrete bent cap
On.Bridge main beam comes to nothing, and on the one hand bridge superstructure is caused to destroy, and on the other hand the shock insulation of laminated rubber bearing is not imitated
It answers, the disease of the bridge substructure of increasing, bridge main beam is directly pounded on concrete bent cap, and huge impact force is formed, and is mixed
Solidifying earth mulch beam is also easy to happen destruction.
Invention content
The utility model causes bridge top and the bottom structure to exist easily to come to nothing when solving existing laminated rubber bearing earthquake
The problem of disease, provides a kind of anti-device that comes to nothing of laminated rubber bearing.
The utility model adopts the following technical scheme that realization：A kind of anti-device that comes to nothing of laminated rubber bearing, including set
The laminated rubber bearing between bridge main beam and concrete bent cap is set, is cased with outside laminated rubber bearing and is supported on concrete bent cap
The bottom end of round steel ring on upper surface, round steel ring is provided with circular steel plate, and circular steel plate lower end is provided with vertical be inserted into and mixes
Anchor bar in solidifying earth mulch beam.
When an earthquake occurs, bridge main beam drives laminated rubber bearing to slide, when board-like under the action of seismic force
Rubber support is slid onto when being touched with round steel ring, and the displacement of laminated rubber bearing is restricted, and then prevents board-like rubber branch
Seat slides into the problem outside bridge main beam support range, has prevented laminated rubber bearing and has come to nothing the generation of phenomenon；Board-like rubber branch
There is certain gap between seat and round steel ring, limited can slide, do not influence the performance of bearing performance when routine use,
It ensure that when earthquake occurs, laminated rubber bearing consumes a part of seismic energy with bridge main beam by sliding, to play
The effect of shock insulation causes asking for bridge top and the bottom Structural defect when overcoming existing laminated rubber bearing earthquake in the presence of easily coming to nothing
Topic.
Round steel ring is structure as a whole with circular steel plate, and the lower end of anchor bar is provided with and extends to horizontal direction
Anti-dropout reinforcing bar.
The setting of anchor bar cooperation anti-dropout reinforcing bar and round steel ring and the integrated design of circular steel plate further increase
The stress and stability of the anti-device that comes to nothing.
It is reliable that the structure design of the utility model is reasonable, has prevented laminated rubber bearing and has come to nothing the generation of phenomenon, and then has solved
The problem of bridge top and the bottom Structural defects, and play the laminated rubber bearing when earthquake occurs and pass through cunning with bridge main beam
It moves a part of seismic energy of consumption and plays the role of shock insulation, ensure that the safety of bridge structure, have simple in structure, easy to process
And advantage at low cost.

Specific implementation mode
A kind of anti-device that comes to nothing of laminated rubber bearing, including be arranged between bridge main beam 1 and concrete bent cap 2 board-like
Rubber support 3, laminated rubber bearing 3 are cased with the round steel ring 4 being supported on 2 upper surface of concrete bent cap outside, round steel ring 4
Bottom end is provided with circular steel plate 5, and 5 lower end of circular steel plate is provided with the vertical anchor bar 6 being inserted into concrete bent cap 2.
Round steel ring 4 is structure as a whole with circular steel plate 5, and the lower end of anchor bar 6 is provided with to horizontal direction and extends
The anti-dropout reinforcing bar 7 gone out.
