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

[0001] The invention relates to a bridge pavement structure, in particular to a continuous reinforcement joint pavement structure for a seamless bridge. Background technique

[0002] In traditional small and medium-sized bridge structures, in order to meet the requirements of bridge structure deformation, expansion joints must be provided between the ends of the two girders, between the end of the girder and the abutment, and a 4m-8m long slab is usually installed behind the abutment. The purpose of setting up the board is to eliminate the abrupt height difference of the staggered platform at the junction of the platform and embankment, so as to improve the driving condition of the road-bridge transition section. The butt plate is completely separated from the main beam structure, and the near end of the platform is supported on the corbel or back wall behind the platform. Traditional bridge structures generally have the maintenance problem of bridge de...
