Description
Technical field
The utility model belongs to bridge technology field, and in particular to a kind of unit assembled noise abatement telescopic device.
Background technology
At present, the telescopic device of domestic and abroad bridge mainly has modulus type (containing single seam), the board-like, gapless of broach etc. several
Class.These types of device has following features:
Modular expansion device is a kind of main product, is manufactured using shaped steel, and seam is stayed to adapt to displacement, shaped steel surface between shaped steel
Wheel support face is formed, suitable for the bridge of various displacements.When shortcoming is that vehicle passes through gap, can generate impact and it is larger
Noise, road-ability is poor, and noise pollution is big.
The board-like telescopic device of broach, which using a pair is mutually twisted combed tooth plate and forms bearing surface and displacement, to be stitched, relative wheel and
Speech, continuous transition on direction of traffic, for vehicle by the way that the impact of generation is small, noise is low, driving is comfortable.Shortcoming is that wheel quickly leads to
After crossing, being detached from fishback, tooth plate inertia knock-on, connecting component fatiguability causes to loosen, come off or damage, and influences traffic safety.
Deformable body blind is mainly done in gapless expansion joint using elastic material, and seamless whole road surface is formed with road surface,
Impact that small, noise is low, driving is comfortable.Shortcoming is material requirements height, and elastomer short life, deflection is small, only can be suitably used for very little
The bridge of across footpath.
In recent years, the advantages of domestic and international scientific research institution and manufacturing enterprise fully combine modulus type and board-like broach, develops
A series of noise abatement telescopic device, core are that combed toothed plate structure is fixed on modulus type section steel surface, modulus existing in this way
Formula is simple in structure, anchoring is reliable, without the advantages of sticking up tooth, the advantages of being provided simultaneously with fishback telescopic device driving steady, low noise,
Therefore a period of time has obtained in bridge, particularly in Urban Bridge extensive utilization.But there is also two for this telescopic device
A main problem, first, the connection bolt or welding of tooth plate and shaped steel, fatiguability destroys under long-term live loading, causes bolt
It comes off or weld cracking influences traffic safety, second is that rubber strip can not be repaired, be replaced.
It summarizes:
Modular expansion device accounts for Chinese market major part market, is domestic main product, suitable for various displacements
Bridge, the larger noise that vehicle can be generated by telescopic device influences urban environment;The board-like telescopic device of broach is a kind of
Noise abatement telescopic device, vehicle is smaller by the noise that telescopic device generates, and is anchored or welded using bolt, and direction across bridge direction point is more
A unit is, it can be achieved that the replacement of local fishback;Broach adds the telescopic device of shaped steel to be a kind of noise abatement telescopic device, broach and type
Using welding or bolt anchoring two ways between steel, during using welding manner, primary disadvantage is that water proof rubber bar can not be more
It changes, during using bolt anchorage style, fishback and bolt are easily loosened, damaged;Gapless telescopic device mainly uses elastic material
Deformable body is done, to material requirements height, deflection very little is primarily adapted for use in the bridge of displacement very little.
Utility model content

The utility model adds the tooth plate of telescopic device of shaped steel and the welding company of shaped steel to solve broach in the prior art
It is connected on fatiguability under long-term live loading to destroy, weld cracking is caused to influence traffic safety, rubber strip can not be repaired, be replaced
The problem of.And provide a kind of unit assembled noise abatement telescopic device.
The technical solution adopted in the utility model is as follows:
A kind of unit assembled noise abatement telescopic device, the band tooth steel plate including being mounted on beam body both sides, both sides in beam body
Broach with tooth steel plate is interlaced, and expansion joint is formed between two broach with tooth steel plate, which is characterized in that the band tooth steel plate
Lower section be both provided with backing plate, two blocks of deformed steels are provided between two backing plates, be connected between two blocks of deformed steels positioned at two band teeth
The waterproof adhesive tape below expansion joint between steel plate broach, backing plate and deformed steel are connect by U-bolt with tooth steel plate;It is described
Backing plate and deformed steel are anchored by anchor slab and anchor ring and the concrete of beam body;Pushing off the slag steel plate is provided with below the band tooth steel plate.
The utility model can disassemble haplotype band tooth steel plate, replace waterproof adhesive tape, finally restore band tooth steel by dismantling bolt-nut
It is quick and convenient to replace vulnerable part for plate.The opening that installation shape chamber is embedded in for waterproof adhesive tape end is provided with below the deformed steel,
The height that shape intracavitary longitudinal direction depth is more than opening is installed
The anchor slab is welded to connect with anchor ring.
The section of the deformed steel is " F " type, and the lower end of deformed steel offers the installation shape for installing waterproof adhesive tape
Chamber, the end insertion installation shape intracavitary of waterproof adhesive tape.
The waterproof adhesive tape section is in " M " font.
The U-bolt anchors together with concrete, forms two layers of anchoring reinforcement mode.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. band tooth steel plate is designed as bolt fastening structure with deformed steel in the utility model, haplotype is removed by substep and is combed
