Description
Technical field
The utility model is related in bridges in highway engineering field, more particularly to a kind of bridge beam body anti-deviation device what is used
The spacing guidance set structure of bridge pier.
Background technology
At present, the in-service medium and small bridges of China's overwhelming majority（Especially continuous curved box girder bridges）Expansion joint is stuck, temperature
Under the effect such as degree effect, bias of quiet dynamic load, its girder is susceptible to significantly lateral shift, and side-play amount is over time
Passage gradually adds up.These bridges that beam body off normal occurs seriously have threaten the safety of road operation, and it is right to be highly desirable to
It is targetedly repaired and is reinforced.Simultaneously for the research of bridge shift phenomenon, not only to study and cause what beam body offset
The method of reason and Deviation Correction Construction and monitoring process, will also try every possible means fundamentally to solve beam body offset problem-i.e. pre- anti-offset
Measure and correction after anti-inclined again measure research.
For the research of the anti-offset measure of bridge beam body, the method that the current country is frequently used has three kinds, three kinds of methods
And its problem for existing is：（1）The method that lateral confinement is carried out using directional support.The method is mainly in the design process,
Easily trigger off normal this problem in view of bridge type feature, by the susceptor design of easy off normal beam section it is in pairs to or three-dimensional about bundle branch
Seat.The shortcoming of this method be preliminary examination phase constraint effect preferably, but at bearing beam body it may happen that larger constraint should
Power；The problems such as follow-up phase is due to the corrosion of bearing itself, deformation, failure causes constraint to be failed, and such as changes not in time, may be right
The safe handling of bridge causes a hidden trouble, and the replacing of bearing construction is pretty troublesome.（2）In beam body both sides, the anti-bias of rigid baffle is set
Shifting method.The method is mainly the bar planting on beam bottom or bent cap, rigid baffle is set by bar planting, by the resistance by force of rigid baffle
Gear prevents beam body from shifting.The above method is primarily present following unfavorable factor：First, anti-bias mode is excessively rigid, belong to strong
Row obstruction formula it is anti-bias, this is not only possible to cause larger beam body internal stress, it is also possible to cause beam body bottom, pier top or bent cap top
Damage；Second, this mode intensity is relatively low, normally only suitable for earthquake motion peak acceleration (Ag≤0.15g) area.（3）
In beam body both sides, the Anti-deviation method of semi-rigid baffle plate is set.With the above method 2, difference is exactly in side to the principle of the method
On the basis of method 2, in rigid baffle and obstacle（Beam body or pier top）Centre filling elastic filler realizes collision or extruding wink
Between transition.Although the above method reduces the infringement of bridge structure part to a certain extent, exist with method 2 same
Problem, i.e., be normally only applied to earthquake motion peak acceleration (Ag≤0.15g) area.
In order to the lateral confinement to bridge beam body is better achieved, and restraint stress can be discharged, reduce safety hidden
Suffer from preventing bridge beam body from offseting.Applicant considers to devise a kind of bridge beam body anti-deviation device, and its feature is, including sets
Two groups of beam body fixation kits of the left and right sides in beam body lower surface in the width direction are put, beam body fixation kit includes one piece of anchoring
Base plate, anchoring base plate is set along beam body width and anchor connection is in beam body, vertical along beam body with one in anchoring base plate
To the displacement following plate for setting straight down, flatly set flexible in the lateral direction between two displacement following plate lower sections
Component, elastic component with the supporting member below beam body be install supporting base.So, anchoring base plate and beam body anchoring are one
Body, can be delivered to displacement following plate, then discharge stress by elastic component by the skew stress concentration on beam body left and right directions
And skew stress is delivered in the supporting member below beam body, therefore the lateral confinement to bridge beam body can be preferably realized,
Release restraint stress, can effectively prevent skew occur, and can will anti-offset during to structure structure injure drop it is small.
But the beam body anti-deviation device, when being specifically applied to bridge pier type bridge, in addition it is also necessary to it may be further contemplated, how to realize it is right
The installation support and the power transmission of horizontal left and right directions of elastic component are oriented to, to facilitate the transmission of stress and preferably discharge stress,
Improve the problem of security.
