Description

Technical Field

[0001] The utility model relates to the technical field of steel member connection, in particular to a support connection structure for the base of a steel pipe column. Background Art

[0002] In the prefabricated steel structure system, the column foot is an important component for connecting the upper structure and the foundation in the steel structure. Welding or anchor bolts are generally used for column feet; in existing construction projects, the construction method of steel column feet is through threaded connection;

[0003] When installing a steel column, the base plate at the bottom of the steel column is fixed to the anchor bolts exposed on the top surface of the foundation with nuts. However, during the construction process, the positions of the steel column foot anchor bolts exposed on the top surface of the concrete foundation often deviate due to the construction of subsequent processes, making it difficult to install the base plate at the bottom of the steel column. It is very difficult for the anchor bolt holes on the column base plate to be aligned with multiple anchor bolts on the installation foundation at the same time. It often requires repeated adjustment, and sometimes the anchor bolt holes need to be made larger, which not only affects the connection strength but also there are deviations in the positions of the steel column foot anchor bolts;

[0004] When installing a steel column, due to the large mass and weight of the steel column, the threads on the steel column foot anchor bolts are often damaged, making it impossible to tighten the anchor bolt nuts, affecting the safety and reliability of the connection.
