Abstract

The invention discloses a joint structure for adding a steel column in an upper structure of a steel structure building and a construction method thereof. The joint structure comprises a herringbone conversion joint, a leg at the top of the herringbone conversion joint is vertically and upwards formed with a column leg for connecting the added steel column, two legs at the bottom of the herringbone conversion joint are obliquely toward two original structure steel columns at the two sides and diagonal braces are respectively connected with the two original structure steel columns, and first reinforced steel beams are connected between the two diagonal braces and between the two original structure steel columns at the adjacent sides of the diagonal braces. Through the joint structure and the construction method thereof provided by the invention, the original structure steel column can be used as a support in a high-rise structure to form a foundation of the added steel column, the needof change is achieved without changing the foundation of a lower structure, and the construction period is saved.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a node structure for adding steel columns to the superstructure of a steel structure building and a construction method thereof. Background technique [0002] In the construction of EPC (Engineering Procurement Construction, "Engineering Procurement Construction") super high-rise steel structure building, the basic structure has been completed due to the late drawing of the superstructure drawings. Due to design requirements, it is necessary to add steel columns and steel beams to the upper structure, such as re-independent foundation construction, which will cost a lot and also have a great impact on the construction period. Therefore, it is urgent to design a steel structure building steel column node to meet the design needs. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention provides a node structure and a c...
