Prefabricated column, pier column structure and construction method

Abstract

The invention discloses a prefabricated column, a pier column structure and a construction method. The structure comprises the prefabricated column. The prefabricated column is arranged on a pile cap through a connecting column, the connecting column and the pile cap are constructed in a cast-in-place concrete way, a bulge or a groove is arranged at the bottom of the prefabricated column, the shape of the top of the connecting column is matched with the shape of the bottom of the prefabricated column, steel plates which partially protrude out of the bottom of the prefabricated column are arranged in the prefabricated column in the longitudinal direction, and hole grooves matched with the steel plates are arranged in the connecting column. According to the invention, the prefabricated column and the connecting column are connected through the bulge and the groove, and then connected with the hole grooves through the steel plates, finally the joints are further sealed through grouting pipes and grouting channels, and thus the connection reliability of the pier column structure is effectively guaranteed. The connection structure is clear in stress, the I-shaped steel plates and wedge notches are arranged, so that the shear-bearing capacity of the structure is improved, rubber strips and epoxy mortars ensure the sealing of the joints, and the structure durability is improved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a prefabricated column, a pier column structure and a construction method. Background technique [0002] At present, most of the construction of general bridge piers in our country is completed by cast-in-place method. This construction method needs to enclose a large enough construction work area, and the construction period is long, requiring erection of supports and consuming a large amount of formwork. Especially for the rail transit built in urban areas, the enclosure of large work space will inevitably occupy a large amount of road resources and hinder traffic travel. Therefore, the construction method of standardized and industrialized production of pier columns in prefabricated yards and on-site installation is just Cater to the needs of the majority of builders. [0003] At present, there are some beneficial attempts for prefabricated pier columns. In the prior art, the conn...

Problems solved by technology

However, the positioning problem in the assembly construction has not been better resolved, and it is easy to affect the service life of the bridge pier

[0005] A connection structure between a prefabricated bridge pier and cap is designed with a shear key to improve the shear performance of the connection structure, but the detailed structure of the connection and the installation accuracy are also not given.
