Socket and spigot joint type connection structure for bridge prefabricated pier stand column and bearing platform and splicing method of socket and spigot joint type connection structure

Abstract

The invention discloses a socket and spigot joint type connection structure for a bridge prefabricated pier stand column and a bearing platform. The structure comprises the stand column and the bearing platform, the stand column comprises an exposed end and an embedded end, the bearing platform is provided with a stand column installing groove in the vertical direction, the cross section shape and the size of the stand column installing groove are matched with the cross section shape and the size of the embedded end so that the stand column can be embedded in the stand column installing groove, and the gap between the outer wall of the embedded end of the stand column and the inner wall of the stand column installing groove is greater than or equal to 2 cm; mud jacking holes are formed in the top face of the bearing platform, first mud outlets are formed in the bottom face of the stand column installing groove, and a mud jacking channel is formed between each mud jacking hole and the corresponding first mud outlet. The invention discloses a splicing method of the socket and spigot joint type connection structure. According to the socket and spigot joint type connection structure for the bridge prefabricated pier stand column and the bearing platform and the splicing method of the socket and spigot joint type connection structure, it is not needed to pre-bury a large number of pre-buried parts in the prefabricated stand column or the bearing platform, the positioning accuracy requirement for site operation is low, the adjusting redundancy is large, and requirements for construction machinery and the like are not high; site steel bar binding and welding and large-scale concrete pouring work are not needed, and site installation is fast, convenient and small in working load.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge prefabricated bridge pier column and socket-type connection structure and an assembly method thereof. Background technique [0002] In the prior art, for the assembly of prefabricated pier columns and caps of bridge structures, pre-embedded sleeves, pre-embedded metal bellows and prestressed steel strands are usually used in the columns or caps, and then the connection in the caps or columns Precise positioning and socketing of steel bars Three types of splicing modes for embedded parts; In addition, there is also a splicing method in which a section of column is prefabricated on the cap at the same time, and a section of cast-in-place section is set between this column and the upper column to connect the prefabricated pier and the cap as a whole . [0003] Since the above three commonly used splicing modes of embedded parts need to embed a large number of e...

Problems solved by technology

[0003] Since the above three commonly used splicing modes of embedded parts need to embed a large number of embedded parts such as sleeves, bellows or prestressed pipes in the columns or caps, and the connecting steel bars and embedded parts in prefabricated components The requirements for construction positioning accuracy are high, and the redundancy of on-site construction adjustment is small, which puts forward very high requirements for construction machinery, equipment, manufacturing and processing, etc. Welding of steel bars and pouring of concrete requires a lot of work on site
