Background technology
Bridge extension joint is the important component part of bridge, the quality of retractor device performance, directly influences the safety of driving and the unimpeded of bridge road.At present, highway in China bridge main shaped steel to be used modular expansion device and common fishback retractor device.In actual applications, both the above retractor device is difficult to control to due to self structure defect and installation quality, all exist fragile, affect girder construction, road-ability is poor, service life is short, the problem such as difficult in maintenance.Wherein, the problems such as the anchor bolt of common fishback retractor device is cut off, nut gets loose happen occasionally；The middle beam vibration of shaped steel modular expansion device, driving noise are big, are also the problems of objective reality.Therefore, at present in the urgent need to a kind of novel bridge extension joint.
Utility model content
Technical problem to be solved in the utility model is just to provide one and had both met the flexible displacement of bridge and seal request, vibrates again vibration and noise reducing bridge extension joint little, that noise is low.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: be included on the concrete component of bridge expanssion joint both sides two be oppositely arranged across seam comb plate, comb joint, water-tight device is provided below across seam comb plate, comb joint, described two are identical across seam comb plate, comb joint structure, each across seam comb plate, comb joint be made up of comb, riser and reinforcing plate, two arranged in a crossed manner across seam comb plate, comb joint, and two comb across seam comb plate, comb joint ride over offside on the riser of seam comb plate, comb joint after intersecting.
Its additional technical feature is: structure that described comb, riser and reinforcing plate is single-casting structure or welding is connected as a single entity；
The front end of described comb is provided with chamfering；
The groove matched with comb it is provided with on described concrete component；
The back side of described riser is provided with anchor bar, and anchor bar is connected with the embedded ribs on concrete component；
Described water-tight device is made up of section bar and rubber weather strip, and section bar is provided with anchor rib；
Described across seam fishback segmentation manufacture.
A kind of vibration and noise reducing bridge extension joint provided by the utility model, compared with prior art, is no longer made up of fixed fingers plate and movable comb tooth plate, and two identical across seam comb plate, comb joint structure, each is made up of comb, riser and reinforcing plate across seam comb plate, comb joint.Two across seam comb plate, comb joint arranged in a crossed manner, be all movable, two across seam comb plate, comb joint comb intersect after ride over offside across seam comb plate, comb joint riser on, for freely supported structure, there is not cantilever, comb load subjected to can be directly delivered in beam body.Hole is the least between comb and comb and between comb front end and beam body, does not jump car, drives a vehicle comfortable, can not form bellows, and noise is little.Structure that comb, riser and reinforcing plate are single-casting structure or welding is connected as a single entity, solid and reliable.The front end of comb is provided with chamfering, reduces the vehicle horizontal impact power to comb, increases the service life of comb.The groove matched with comb it is provided with, the extendable room of reserved comb on concrete component.The back side of riser is provided with anchor bar, and anchor bar is connected with the embedded ribs on concrete component, solid and reliable, after casting concrete, forms one with beam or abutment, vibrates little.Water-tight device is made up of section bar and rubber weather strip, and section bar is provided with anchor rib, good airproof performance, and easy for installation, rubber weather strip is at the bottom of retractor device, it is to avoid sunlight direct irradiation, extends service life.Manufacture across seam fishback segmentation, it is simple to transport and install.
