Connecting construction between prefabricated bridge pier and bearing platform and capable of positioning attitude

Abstract

The invention belongs to the technical field of bridge engineering, and discloses a connecting construction between a prefabricated bridge pier and a bearing platform and capable of positioning the attitude. The connecting construction comprises the prefabricated bridge pier and the bearing platform arranged under the prefabricated bridge pier, the bearing platform comprises a pre-casting part anda post-casting part which are connected vertically, the center of the pre-casting part is provided with a boss, the boss is aligned with the center of the prefabricated bridge pier, the prefabricatedbridge pier is internally provided with multiple longitudinal tensioned bars arranged circumferentially around the projection of the boss on the prefabricated bridge pier, the longitudinal tensionedbars stretch out of the bottom of the prefabricated bridge pier and extend in the height direction of the boss, and the post-casting part is located around the boss and makes the longitudinal tensioned bars, the pre-casting part and the post-casting part combined tightly; multiple telescopic devices uniformly arranged around the periphery of the boss are arranged between the bottom face of the prefabricated bridge pier and the root of the boss of the pre-casting part, the telescopic devices are located between the longitudinal tensioned bars and the boss, and telescopic ends of the telescopicdevices are connected with the prefabricated bridge pier. The connecting construction between the prefabricated bridge pier and the bearing platform and capable of positioning the attitude has the advantages that the positions of the prefabricated bridge pier and bearing platform are positioned accurately, and the post-casting part can ensure that the prefabricated bridge pier and the bearing platform form a stable combination body.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a connection structure between a prefabricated bridge pier and a cap capable of positioning postures. Background technique [0002] In the prior art, the assembly of prefabricated piers and caps of bridge structures usually adopts embedded parts such as embedded sleeves, pre-embedded bellows or prestressed pipes in the piers or caps, and then the connecting steel bars in the caps or piers Precisely locate the splicing mode of socket embedded parts. [0003] The splicing modes of the above commonly used embedded parts all need to embed a large number of embedded parts such as sleeves, bellows or prestressed pipes in the columns or caps, and have high requirements for the construction positioning accuracy of the connecting steel bars and embedded parts in the prefabricated components. , There is little room for on-site construction adjustment, and very strict requiremen...
