A kind of super high-rise building core tube steel column connection structure and core tube construction method

Abstract

The application relates to a steel column connection structure of a core tube of a super high-rise building and a construction method of the core tube, and relates to the technical field of high-rise building engineering, which includes a steel column and a beam. There is a fixing plate, a reinforcement frame is fixed in the groove of the steel column, the interior of the reinforcement frame is hollow, a plurality of threaded cylinders are fixed on the inner wall of the groove of the steel column, the cylinder hole is opened in the reinforcement frame, and a flange plate is fixed at one end of the beam. The flange plate is in contact with the outer wall of the reinforcement frame, the flange plate is provided with a first round hole, a fixing bolt is abutted in the first round hole, and the fixing bolt passes through the first round hole and the reinforcement frame and is threadedly connected with the threaded barrel; The inner wall of the frame is fixed with a reinforcement plate, the threaded barrel is also fixed on the reinforcement plate, the flange plate is in contact with the flange of the steel column, and the fixing bolts pass through the first round hole, the flange of the steel column, the rear of the reinforcement frame and the reinforcement plate in sequence. The threaded barrel is threadedly connected, and the present application has the effect of improving the strength of the connection between the steel column and the beam, thereby improving the strength of the core barrel.

Description

technical field [0001] The present application relates to the technical field of high-rise building engineering, in particular to a core tube steel column connection structure of a super-high-rise building and a core tube construction method. Background technique [0002] The core tube is the central part of the building. The central core tube surrounded by elevator shafts, stairs, toilets and other parts forms an outer frame and inner tube structure with the outer frame of the building, which is poured with reinforced concrete. Because the core tube structure has the characteristics of high strength and high economic efficiency, the core tube structure is often used in high-rise and super high-rise buildings. [0003] In the related art, the core tube is generally made of steel columns, beams, and steel bars. The steel columns are located at the four corners of the core tube and are connected with the steel column flanges below. Connected and connected, steel bars are stag...
