Description
Technical field
The utility model relates to road and bridge field more particularly to a kind of long-life freedom from repairs bridge extension joint central sills.
Background technique
With the development of China's communication, the magnitude of traffic flow and vehicle load increasingly increase, existing highway bridge expansion joint field
There are various problems:
Often there is stone to fall into an expansion joint and just do hole to come out, in this case, water can enter damage bridge and stretch
Contracting crack structure；
When some sanitationman sweep, not diligently, stone is fallen into onto waterstop, oneself also pokes and stone is allowed to fall down
It goes；After having hole, water will enter bridge gap, and bridge can be damaged if icing, can corrode associated components, the time, which has been grown, to be easy to make
At accident.
In telescopic device after waterstop damage, corrosive substance such as bridge floor sewage, winter deicing salt water can pass through sealing
The breakage of band leaks, and can destroy a bridge support, destroys reinforcing bar, influences the use function of bridge, cause the security risk of bridge.
Traditional single layer waterstop service life is shorter, need to frequently replace, can shadow if waterstop is replaced during operation
Ring traffic.
Utility model content
The purpose of utility model: in order to provide a kind of effect preferably atraumatic bridge expanssion joint waterstop central sill,
Specific purposes are shown in multiple substantial technological effects of specific implementation part.
In order to reach purpose as above, the utility model adopts the following technical scheme:
A kind of long-life freedom from repairs bridge extension joint central sill, which is characterized in that in being used cooperatively with waterstop
Beam beam body includes clamping groove in the central sill beam body, and the structure that is caught in of waterstop is inserted into clamping groove, the clamping
Groove avris includes protrusion, includes the recess that can agree with protrusion below waterstop, and the lower section which holds central sill is convex
Waterstop can be fixed by rising；The clamping groove is located at the two sides of central sill.
The further technical solution of the utility model is, the raised central portion relative narrower；End is relatively wide, therefore
It can be close with recess clamping.
The further technical solution of the utility model is, includes upper hem above the clamping groove, and upper hem is to incline
Oblique side, the trimming thereon comprising a mutation.
Using the utility model of technical solution as above, have the advantages that compared with the existing technology: the above structure rises
To effect be that one layer of protection structure is added to waterstop, i.e., increase on it new steel wire either gap steel plate,
It can be avoided heavier stone and break through waterstop, while being avoided that people stabs rotten waterstop, so as to preferably export water
It goes, prevents corrosion etc. of the water to bridge ontology.The steel wire either gap steel plate neither influences the flexible of waterstop, again
Its intensity can be increased, guarantee its safety.

This patent provides a variety of concomitant regimens, in place of different expression, belong to modified scheme based on basic scheme or
It is parallel type scheme.Every kind of scheme has the unique features of oneself.
A kind of long-life freedom from repairs bridge extension joint central sill, which is characterized in that in being used cooperatively with waterstop
Beam beam body includes clamping groove in the central sill beam body, and the structure that is caught in of waterstop is inserted into clamping groove, the clamping
Groove avris includes protrusion, includes the recess that can agree with protrusion below waterstop, and the lower section which holds central sill is convex
Waterstop can be fixed by rising；The clamping groove is located at the two sides of central sill.
The technical effect and its realization process for the essence that the technical solution at this place is played are as follows: compared with the existing technology
In central sill, this structure can facilitate clamping, and clamping effect is more preferable, so that waterstop is not easily to fall off, clamping is close, meanwhile, by
Close in clamping, waterstop integrally has certain clamping force to protrusion 5, can effectively play clamping effect, and water will not be from
It is penetrated into the gap of waterstop and clamping groove, waterproof effect is more preferable.
The raised central portion relative narrower；End is relatively wide, therefore can be close with recess clamping.The folder of the structure
Holding effect fruit is more preferable.
It include upper hem above the clamping groove, upper hem is inclined side, the trimming thereon comprising a mutation.
The technical effect for the essence that the technical solution at this place is played and its realize that process be as follows: the inclined side tilt upward, because
This water, which is not likely to enter in the gap of waterstop and clamping groove, to penetrate into, and waterproof effect is more preferable.
A kind of atraumatic bridge extension joint, which is characterized in that telescopic device includes side bar, central sill and sealing
Band includes waterstop, and waterstop includes comprising sealing band body, and sealing band body includes sealing subzonal layer 3 and and waterstop
The waterstop upper layer 4 that lower layer 3 fits closely, the sealing subzonal layer 3 are rubber material, and the waterstop upper layer 4 is steel
Silk screen either gap steel plate.The technical effect and its realization process for the essence that the technical solution at this place is played are as follows: only
The waterstop upper layer 4 that water subzonal layer 3 fits closely constitutes the entirety of waterstop；
After top has stone to fall, stone can be blocked by waterstop upper layer 4, avoided it from hitting and worn waterstop.This place
Stone, which can also be, is difficult to expect other objects on road surface.
The effect that the above structure plays is that one layer of protection structure is added to waterstop, i.e., increases new steel wire on it
Net either gap steel plate, can be avoided heavier stone and breaks through waterstop, while be avoided that people stabs rotten waterstop, enable it to
It is enough preferably to go water export, prevent corrosion etc. of the water to bridge ontology.The steel wire either gap steel plate neither shadow
The flexible of waterstop is rung, and its intensity can be increased, guarantees its safety.
