Description

Technical Field

[0001] The utility model relates to a reinforcement butt joint auxiliary positioning device for bridge pier construction. Background Art

[0002] The usual practice for bridge pier construction is as follows: after the final setting of the abutment, the reinforcement of the first section of the cast-in-place concrete pier is overlapped (i.e., overlapped with the reserved reinforcement on the top of the abutment) and the reinforcement is tied. After the reinforcement cage of the first section of the cast-in-place concrete pier is tied, the formwork of the first section of the cast-in-place concrete pier is erected, and then the first section of the cast-in-place concrete pier is cast. After the maintenance of the first section of the cast-in-place concrete pier is completed, the reinforcement of the second section of the cast-in-place concrete pier is overlapped (i.e., overlapped with the reserved reinforcement on the top of the first section of the cast-in-place concrete pier) and the reinforcement is tied. After the reinforcement cage of the second section of the cast-in-place concrete pier is tied, the formwork of the second section of the cast-in-place concrete pier is erected, and then the second section of the cast-in-place concrete pier is cast. And so on and so forth, to complete the construction of the entire cast-in-place concrete pier. In order to improve construction efficiency, prefabricated steel cages can be used for cast-in-place concrete piers. At this time, the steel bar binding work of each section of the cast-in-place concrete pier will be completed in advance in the factory. The construction site only needs to install the prefabricated steel cage of the upper cast-in-place concrete pier on the reserved steel bars on the top of the lower cast-in-place concrete structure, and then the cast-in-place concrete pier formwork can be erected.
