Abstract
The invention discloses a continuous reinforcement distribution wiring road structure for a seamless bridge, which comprises a structure continuing or deck continuing main girder (1), a semi-integral type or integral type abutment (2), a butt strap (3), a corbel (4) and a continuous reinforcement distribution wiring road (5); the near abutment end of the butt strap (3) is connected with the main girder (1) through a main steel reinforcement (7); the long abutment end of the butt strap (3) is positioned on the corbel (4); the continuous reinforcement distribution wiring road (5) is connected with the butt strap (3) through the adoption of a monolayer through steel reinforcement (8) set in full duration; and the bottom end of the continuous reinforcement distribution wiring road (5) can be provided with an anchoring block (6). The continuous reinforcement distribution wiring road structure removes telescopic seam between the girder end and the abutment and road-bridge telescopic seam between the bottom end of the butt strap and the wiring road, has convenient design and construction, is in particular suitable for middle and small-size bridges, and can effectively reduce the maintenance expense of the bridge.
Description
Technical background
The present invention relates to a kind of bridge pavement structure, particularly relate to structure of continuously reinforced link road pavement for seamless bridge.
Background technology
In traditional medium and small bridge construction, be to adapt to the requirement of bridge construction distortion, must the long attachment strap of 4m-8m be set usually behind the abutment between two beam-ends, between beam-ends and the abutment, the shrinkage joint is set.The purpose of attachment strap setting is to eliminate the faulting of slab ends discrepancy in elevation of platform dike joining place sudden change, to improve the driving situation of road-bridge transition section.Attachment strap separates fully with main beam structure, and near platform end is supported in behind the platform on bracket or the parados.The maintenance issues of traditional bridge construction ubiquity deck expansion joint.
In medium and small bridge, the standard practice of building monolithic (semi-monolithic formula) seamless bridge technology is: cancellation full-bridge shrinkage joint, comprise the shrinkage joint between once requisite beam-ends and the abutment, girder closely is connected with attachment strap (or claiming settlement plate), attachment strap (or claiming settlement plate) adopts the ground type setting, the gradient is concordant with road, with beam body dilatation, bigger road and bridge seams is set to receive the distortion of bridge between attachment strap end and road pavement.External seamless bridge design is owing to being provided with bigger road and bridge expansion or contraction joints, so still exist the shrinkage joint to safeguard the replacing problem.
Summary of the invention
Technical problem to be solved by this invention provides a kind of shrinkage joint of both having eliminated between beam-ends and the abutment, eliminate the road and bridge shrinkage joint between attachment strap end and the road pavement again, design and construction are convenient, can reduce the structure of continuously reinforced link road pavement for seamless bridge of bridge inspection and maintenance expense.
In order to solve the problems of the technologies described above, structure of continuously reinforced link road pavement for seamless bridge provided by the invention, comprise structure is continuous or bridge floor is continuous girder, semi-monolithic formula or monolithic abutment, attachment strap, sleeper beam, continuously reinforced link road pavement, the attachment strap near platform end closely is connected by main muscle with girder, the far platform end of attachment strap places on the sleeper beam, and the elongated reinforcing bar of individual layer that described road pavement adopts full duration to be provided with is connected with described attachment strap.
If during the continuously reinforced link road pavement length limited, can be provided with anchor block at described road pavement end.
Adopt the structure of continuously reinforced link road pavement for seamless bridge of technique scheme, cancelled the road and bridge seam of seamless bridge, the elongated reinforcing bar of individual layer that road pavement adopts full duration to be provided with is connected with attachment strap, realized that fully full-bridge and road pavement are all seamless, really realized " zero dimension is protected ", reduced maintenance cost; Owing to thoroughly solve the stretching device problem, improve the driving comfort of highway, improve durability of structures, social benefit is obvious; Patent of the present invention not only can be used for newly-built bridge construction, more can conveniently be used to exist the strengthening reconstruction work of the old bridge of abutment place stretching device problem, has wide range of applications.Patent of the present invention is specially adapted to the medium and small footpath seamless bridge structure of striding, and can be used for all pavement structures.
In sum, the present invention is a kind of shrinkage joint of both having eliminated between beam-ends and the abutment, eliminates the road and bridge shrinkage joint between attachment strap end and the road pavement again, and design and construction are convenient, be particularly suitable for medium and small bridge, can reduce the structure of continuously reinforced link road pavement for seamless bridge of bridge inspection and maintenance expense.
