Abstract
This utility model belongs to means of transportation technical field, is specifically related to a kind of dust control and noise absorption bridge extension joint without welding.Include a pair fishback, it is characterised in that fishback is fixing with anchor plate to be connected, and is directly embedded in concrete, and anchor plate is interted fixing connection that interlock by elongated reinforcing bar with embedded bar, and waterstop is connected by fixing angle steel and anchor plate are fixing；Dust-proof sound-absorbing material it is provided with between described fishback and waterstop.Beneficial effect: fishback need not be fixed by bolt welding so that it is surface is the most smooth, smooth, trafficability can be more steady, reduces Vehicular vibration and reduces noise.Simultaneously fishback and between dust-proof sound-absorbing material is set, not only act as dustproof effect, also meet the damping noise reduction demand of retractor device.
Description
Technical field
This utility model belongs to means of transportation technical field, is specifically related to a kind of dust control and noise absorption flexible without the bridge of welding
Device.
Background technology
In recent years, along with the increase of infrastructure investment, highway field obtains the development advanced by leaps and bounds, answering of retractor device
With more universal, it comes into question and also gets more and more.As due to bolt fracture or nut loosening thus cause fishback to take off
Fall, cause vehicle pass-through inconvenience；Vehicle travel process produces noise problem, to factory, school, particularly community around highway
Office and the life of resident make a big impact.A kind of dust control and noise absorption of this utility model is without the retractor device of welding, it is not necessary to
It is bolted fishback, from without producing the problem causing fishback to come off due to bolt fracture or nut loosening.
Fishback is more smooth without open surface, smooth simultaneously, reduces vehicle by the vibration produced.This utility model is also at comb
It is provided with dust-proof sound-absorbing material between plate and waterstop, is possible not only to dust-proof, vibration damping, moreover it is possible to absorb road noise, reduce noise dirty
Dye, protects environment.
Utility model content
The purpose of utility model: in order to provide a kind of more preferable rolling stock wheel of effect that more changing device, specific purposes are shown in
It is embodied as multiple substantial technological effects of part.
In order to reach as above purpose, this utility model adopts the following technical scheme that:
Scheme one:
A kind of dust control and noise absorption, without the bridge extension joint of welding, includes a pair fishback, it is characterised in that fishback
Directly fix with anchor plate and be connected and without being bolted, anchor plate and embedded bar are interted by elongated reinforcing bar to be handed over
Wrong fixing connection, waterstop is connected by fixing angle steel and anchor plate are fixing；It is provided with between described fishback and waterstop
Dust-proof sound-absorbing material, described dust-proof sound-absorbing material can absorb noise.
The further technical scheme of this utility model is, a pair described fishback connected mode is arranged crosswise.
The further technical scheme of this utility model is, described anchor plate pattern is appointing in hollow, gate, square
Meaning one.
The further technical scheme of this utility model is, comprises the rubber layer of more than a layer below described waterstop.
The further technical scheme of this utility model is, comprises space between described rubber layer.
Scheme two:
A kind of dust control and noise absorption is without the bridge-collision-avoidance method of the bridge of welding, it is characterised in that utilize dress as above
Putting, dust-proof sound-absorbing material is prevented from two bridge plates and collides with one another.
Use this utility model of as above technical scheme, have the advantages that relative to prior art: fishback is not required to
Bolt welding to be passed through is fixed so that it is surface is the most smooth, smooth, reduces Vehicular vibration.Simultaneously fishback and between arrange
Dust-proof sound-absorbing material, not only acts as dustproof effect, also meets the damping noise reduction demand of retractor device.

Detailed description of the invention
Illustrating embodiment of the present utility model below in conjunction with the accompanying drawings, embodiment is not constituted limit of the present utility model
System:
A kind of dust control and noise absorption, without the bridge extension joint of welding, includes a pair fishback, it is characterised in that fishback
Directly fix with anchor plate and be connected and without being bolted, anchor plate and embedded bar are interted by elongated reinforcing bar to be handed over
Wrong fixing connection, waterstop is connected by fixing angle steel and anchor plate are fixing；It is provided with between described fishback and waterstop
Dust-proof sound-absorbing material, described dust-proof sound-absorbing material can absorb noise.The technology effect of the essence that the technical scheme at this place is played
Fruit and the process that realizes thereof are as follows: fishback need not be fixed by bolt welding so that it is surface is the most smooth, smooth, reduce
Vehicular vibration.Simultaneously fishback and between dust-proof sound-absorbing material is set, not only act as dustproof effect, also meet retractor device
Damping noise reduction demand.
Compared to the prior art, distance is same, from bridge horizontal range 18M: find that noise vs is: prior art is
70db;This patent is 30db.
As preferably, described waterstop is preferably the structure of arc, can be rubber or other water-retaining structures, even
It it is the metal of some dash.
Described a pair fishback 1 connected mode is arranged crosswise.
The rubber layer of more than one layer is comprised below described waterstop 4.Space is comprised between described rubber layer.The technology at this place
Technique effect and the process that realizes thereof of the essence that scheme is played are as follows: rubber layer and air layer make to insulate against sound damping effect more
Good.When bridge is by External Force Acting, bridge superstructure can be subjected to displacement deformation, and this retractor device is that combed is intersected, can be certainly
By stretching, meet the displacement deformation occurred.Retractor device produces vibration and noise under vehicle loading, by using dust-proof suction
Sound material, will vibrate and slowed noise and absorption, reach the function of antivibration and anti-noise.
As the most preferably, a kind of dust control and noise absorption is without the bridge-collision-avoidance method of the bridge of welding, it is characterised in that
Utilize device as above, dust-proof sound-absorbing material to be prevented from two bridge plates to collide with one another.
In a creative way, each effect above is individually present, moreover it is possible to complete the combination of the above results with a nested structure.
The technique effect that above structure realizes realizes clear, and discounting for additional technical scheme, this patent title is also
It can be a kind of bridge structure.Part details not shown in figure.
It should be noted that multiple schemes that this patent provides comprise the basic scheme of itself, separate, the most mutually
Restriction, but it can also be mutually combined in the case of not conflicting, and reaches multiple effect and jointly realizes.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Ability
Territory skilled person will appreciate that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model also can
Having various changes and modifications, these changes and improvements both fall within claimed scope.
