Description
Technical field
The utility model relates to a kind of road pavement of bridge constructions, more particularly to a kind of list for large and medium-sized bridge
Telescopic device bridge road and bridge seamless connection structure.
Background technique
In the bridge structure of the prior art, the problem of bridge structure generally existing deck expansion joint rapid wear difficulty maintenance.It is whole
The standard practice of formula bridge is to consolidate flexible abutment and girder, and the temperature deformation of girder mainly passes through the longitudinal direction of flexible pile under platform
Displacement is received；Rigid abutment is then connect by semi-monolithic formula bridge with zero moment of flexure of girder, and the vertical of girder is received by the displacement of stake
To displacement.But this entirety or semi-monolithic formula bridge are provided with road and bridge seam, however it remains the cracking of seam and maintenance replacement etc.
Problem.
Utility model content
The purpose of this utility model is that: Abutment girder and the equal seamless surface of road pavement are realized, bridge is reduced
Maintenance cost, and road pavement does not need configuration reinforcement, the time needed for reducing reinforcing bar binding, shortens the duration.
The technical problem to be solved by the utility model is to provide a kind of telescopic device eliminated between beam-ends and abutment,
To cancel the road and bridge seam between attachment strap end and road pavement again, can be suitably used for the large and medium-sized bridge of 100m-300m, design is simple,
Convenient and quick construction, and a kind of road and bridge suitable for large and medium-sized bridge that can be reduced bridge life cycle management maintenance cost are seamless
Connecting structure.The technical solution adopted in the utility model is as follows: a kind of road and bridge seamless connection structure for large and medium-sized bridge, packet
Include that structure is continuous or the continuous girder of bridge floor, bridge pier, full-bridge center pier coping portion setting one of telescopic device, half whole
Body formula or Integral Abutment and road pavement offer L-shaped groove on the junction top of two girders, are realized and are led by telescopic device
Connection between beam；Telescopic device includes a plurality of I-steel, marine glue；A plurality of I-steel is arranged in L-shaped groove for connecting master
Beam, marine glue are arranged below L-shaped groove for sealing, waterproof, connect girder；The expansion joint for cancelling Abutment end of main beam, connects
The near platform end of circuit surface is connected with the girder for only setting telescopic device together by connection reinforcing bar, and the far platform end of road pavement is placed in anchor
Gu on component；Road pavement uses the high performance concrete containing steel fibre, and road pavement does not need configuration continuity reinforcement(bar)；Its
In, anchorage element uses inverted T-shaped structure；Girder, road pavement upper surface asphalt concrete pavement layer.Further, it connects
One of anchorage element is set by every 5-6M below circuit surface.
To sum up, by adopting the above-described technical solution, stretching the beneficial effects of the utility model are: thoroughly solving abutment
The problem of device, reduces vehicle bump at bridge ends, improves driving road-condition, enhances driving comfort level, improves the resistance to of structure
Long performance and anti-seismic performance, social benefit are obvious.The utility model patent can be not only used for newly building bridge structure, it may also be used for
There are problems that the strengthening and rehabilitation of old bridges work of abutment telescopic device, application prospect is extensive.The utility model patent especially suitable for
Large and medium-sized bridge structure can be used for all road pavement constructions.
To sum up, the utility model is a kind of telescopic device not only eliminated between beam-ends and abutment, but also cancels attachment strap end
Road and bridge seam, simple, the easy for construction, speed of application of design it is quick, especially suitable for large and medium-sized bridge, can be reduced the bridge full longevity
Order the seamless connection structure of periodic maintenance expense.
