Description
Technical field
The invention belongs to science of bridge building fields, are related to a kind of cross-linking air partition structure of adaptation expansion joint displacement.
Background technique
Currently, air partition structure is arranged on main bridge or on access bridge more at home and abroad using in the bridge of air partition structure, but
It is in main bridge and access bridge junction because the setting at expansion joint is so that bridge longitudinally has displacement, traditional air partition structure is unable to satisfy
Displacement demand, therefore air partition structure is not provided in expansion joint beam section.In view of in bridge driving conditions, expansion joint beam section is same
There is the demand kept out the wind in sample, therefore objectively need to propose a kind of cross-linking bridge air partition of adaptation expansion joint displacement, replace solid
Surely hinder traditional air partition of item, to meet the requirement of bridge dilatation.
Summary of the invention
The purpose of the present invention is to provide a kind of cross-linking air partition structures of adaptation expansion joint displacement, replace fixed barrier item
Traditional air partition makes it that can meet the displacement of beam section at expansion joint.Air partition structure should have enough deformation energy in the longitudinal direction herein
Power to meet the requirement of bridge dilatation, and needs to have certain ability of keeping out the wind.
In order to achieve the above objectives, the technical scheme adopted by the invention is that:
It is a kind of adapt to expansion joint displacement cross-linking air partition structure, be arranged be interspersed on air partition column the blade that keeps out the wind (or
Barrier item) (hereinafter referred to as barrier item) be reciprocally moveable, to meet because of expansion joint displacement caused by hinder a column Relative sliding.
A barrier side fixing end is fixedly connected with air partition column, and other side free end passes through the hole being opened on column web
Hole.
It is equipped with idler wheel at column web hole, relatively reciprocal fortune is guaranteed with the contact of the blade that keeps out the wind (or barrier item) by idler wheel
Dynamic generation, and the degree of stability being kept in contact.
Hinder a free end there are certain excess length, depending on the displacement capabilities at the basis of design expansion joint of excess length, needs
Meet the barrier length in maximum displacement and covers region of keeping out the wind.
Specifically, a kind of cross-linking air partition structure for adapting to expansion joint displacement, the cross-linking air partition structure includes wind
Hinder column, Windbreak barrier strip；It include that cross-linking hinders item in the Windbreak barrier strip, one end of the cross-linking barrier item is and air partition column
The fixing end being fixedly connected, the other end are the free end that passes through from the hole opened up on the web of air partition column, it is described from
The overlay segment in one section of front-rear position is formed with the Windbreak barrier strip of adjacent segment by holding.
Further, it is preferable that further include idler wheel and fixed device, the idler wheel is fixed on air partition column by fixed device
Web on；The cross-linking barrier item contacts near described hole with the idler wheel to reduce barrier item and pass through rubbing for column web
The stability wiping resistance and being kept in contact.
Preferably, there are excess length, the basis of design of the excess length is flexible for the free end of the cross-linking barrier item
Depending on the displacement capabilities of seam, the length that need to meet the Windbreak barrier strip in maximum displacement covers region of keeping out the wind.
Preferably, the material of the Windbreak barrier strip is steel, alloy material, transparent or semitransparent high molecular material or glass
Plate.
As the above scheme is adopted, the invention has the advantages that the displacement for efficiently solving expansion joint position air partition is asked
Topic is, it can be achieved that Windbreak barrier strip length freely changes between column；It realizes the continuity that bridge air partition keeps out the wind, is conducive to driving peace
Entirely；The Windbreak barrier strip, which interts device, simply has actual effect.
Detailed description of the invention
Figure 1A is a kind of cross-linking bridge air partition front schematic view for adapting to expansion joint displacement of the present invention.
Figure 1B is Figure 1A illustrated embodiment cross-linking bridge air partition side schematic view.
Fig. 2 is the drawing of barrier item of the embodiment of the present invention；
Fig. 3 is to hinder item and column connecting portion construction (vertical view) schematic diagram in Figure 1A illustrated embodiment.
Specific embodiment
Invention is further illustrated below in conjunction with the embodiment shown in that figure.
Figure 1A and Figure 1B is a kind of cross-linking bridge air partition front for adapting to expansion joint displacement of the present invention and side signal
Figure, air partition structure are mounted on anticollision barrier 1, are suitable for 2 place beam section of expansion joint, which includes air partition column 3, is worn
The formula of inserting hinders item 5, idler wheel 502 and fixed device 503.Hole 501 is wherein opened up on a heel post web 301, cross-linking hinders item 5
Free end is passed through from the hole 501, and overlay segment (the spatially anteroposterior position of certain area is formed with the tradition barrier item 4 of adjacent segment
Set), the length of overlay segment is arranged according to the displacement capabilities at expansion joint.Idler wheel 502 passes through fixed device 503 and is fixed on web 301
On.
Cross-linking barrier item 5 contacts near the hole 501 of web 301 with idler wheel 502, when cross-linking hinders the movement of item 5, idler wheel
502 roll simultaneously, and idler wheel 502 opposite can reduce the stabilization journey that barrier item passes through the frictional resistance of column web 301 and is kept in contact
Degree ensures that cross-linking barrier item 5 reciprocatingly slides with the steady of air partition column 3.
In use, anticollision barrier 1 and air partition column 3 follow beam section phase when the displacement of bridge expanssion joint 2 increases (or reducing)
It should conjugate, the opposite barrier item of air partition column 3 generates sliding at this time, and region of keeping out the wind is elongated (or short), and cross-linking hinders 5 free end of item
(or long) can be correspondingly adjusted and shortened with adjacent segment tradition blade overlapping region of keeping out the wind.Idler wheel 502 effectively ensures that cross-linking hinders
The generation of the relative motion of item 5 and air partition column 3, reduces the loss in its motion process, to meet air partition structure for stretching
The requirement of contracting displacement.
In conclusion a kind of cross-linking bridge air partition for adapting to expansion joint displacement of the present invention, by air partition column and is interspersed in
The Windbreak barrier strip composition that can be moved back and forth on air partition column.Windbreak barrier strip may pass through the hole being opened on column web, and
There are certain length deposits, and when with girder length travel occurs for column, Windbreak barrier strip is realized and column by idler wheel
It moves back and forth, to play the effect kept out the wind.
In use, air partition column is mounted on deck expansion joint guardrails of both sides by the way that connecting plate is fixed or movable, the beam section
Air partition adjusts length by the Relative sliding of Windbreak barrier strip and column, so that this keeps out the wind, air partition has flexible displacement good
Adaptability.
The above-mentioned description to examples of implementation is that this can be understood and applied for the ease of those skilled in the art
Invention.Person skilled in the art obviously easily can make various modifications to these embodiments, and illustrating herein
General Principle be applied in other embodiments without having to go through creative labor.Therefore, the present invention is not limited to realities here
Example, those skilled in the art's announcement according to the present invention are applied, improvement and modification made without departing from the scope of the present invention all should
Within protection scope of the present invention.
