A method for manufacturing a composite steel column in the crown transition section of a super high-rise building

Abstract

The invention discloses a method for manufacturing a combined steel column in the crown transition section of a super high-rise building. The combined steel column includes a vertically arranged steel column, upper corbels and lower corbels arranged on the steel column at intervals, and the steel column From bottom to top, it consists of orthogonal H-shaped steel column section, connecting H-shaped steel column section, oblique H-shaped steel column section and diamond-shaped steel column section; orthogonal H-shaped steel column section, connecting H-shaped steel column section and oblique H-shaped steel column section The center line of the web plate of the section is located on the same straight line; the lower corbel is set on the connecting H-shaped steel column section; the left and right flange plates are respectively arranged between the upper and lower flange plates at the upper end of the oblique H-shaped steel column section. Both sides of the flange plate and the right flange plate are fixedly connected with the edge of the lower flange plate and the corresponding edge of the upper flange plate to respectively close the left and right sides of the upper and lower flange plates, and the inclination angle of the diamond-shaped steel column section corresponds to the inclination angle of the tower crown. The fabricated composite steel column can effectively realize the transition from the main structure of the tower to the crown structure.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a method for manufacturing a combined steel column at the crown transition section of a super high-rise building. Background technique [0002] With the further development of super high-rise buildings, more and more super high-rise buildings need lateral force-resisting structural systems such as outer frame columns + core tubes + reinforced layer outrigger trusses to meet the structural design requirements. The main stress-bearing structural system of the outer frame column is usually a large-section combined steel column to ensure that the entire tower can exert its advantages in compression, torsion, and earthquake resistance under the action of gravity or external force. Corbels connected to the steel beams of each floor are arranged on the outer frame columns, and the corbels play a role in the stability of the connection between components to a large extent...

Problems solved by technology

Therefore, when the main body of the tower transitions to the tower crown, the outer frame steel column should be converted from the H-shaped section of the original rigid steel column to the diamond-shaped section structure. However, this type of section conversion has never been used in previous projects, and there is no reference. Therefore, How to realize the conversion of cross-section form and cross-section size has become a key problem in the production of steel columns in the transition section from the main structure of the tower to the crown structure.
