Girdle truss, manufacturing method of girdle truss and super high-rise building giant frame

Abstract

The invention relates a girdle truss, a manufacturing method of the girdle truss and a super high-rise building giant frame. The girdle truss comprises an upper chord, a lower chord and a corrugated steel web, wherein the upper chord adopts a steel tube concrete-filled upper chord, the lower chord adopts a prestressed steel tube concrete-filled core rod, and the upper end and the lower end of thecorrugated steel web are in rigid connection with the upper chord and the lower chord respectively to form the girdle truss; and a plurality of honeycomb through holes are formed in the corrugated steel web at equal intervals. According to the girdle truss, the manufacturing method of the girdle truss and the super high-rise building giant frame, the steel tube concrete-filled upper chord is usedas an upper chord member of the girdle truss, so that the compression bearing capacity and rigidity of the upper chord of the girdle truss are enhanced; the prestressed steel tube concrete-filled corerod is used as a lower chord member of the girdle truss, so that the tensile bearing capacity and rigidity of the lower chord of the girdle truss are improved; the corrugated steel web with the honeycomb through holes are adopted to replace a girdle truss diagonal web member, so that the shear bearing capacity is improved, daylighting performance and permeability of the girdle truss are improved,and girdle truss construction is simplified. The girdle truss is excellent in stress performance and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of super high-rise building frames, in particular to an annular truss, a method for manufacturing the annular truss, and a super high-rise building giant frame. Background technique [0002] As the research on the structural system of super high-rise buildings is becoming more and more perfect, super high-rise buildings have sprung up and completed. As the "business cards" of cities and countries, super high-rise buildings have become a symbol of a country's national spirit and the rise of urban economy. [0003] As the height of super high-rise buildings increases, the wind and earthquake effects they bear also increase significantly. General building structural systems are not competent. Super high-rise buildings usually adopt a giant frame-core tube structural system with strong resistance. In the structural system of super high-rise buildings, the core tube usually exists inevitably, and its resistance c...

Problems solved by technology

[0005] At present, ring-belt trusses are usually made of steel structures. However, steel-structure ring-belt trusses have disadvantages such as high cost, poor structural stability, low bearing capacity, and difficult construction. The engineering community urgently needs to develop a steel pipe concrete composite structure. Belt truss, construction technology reform for the belt truss of giant frame-core tube structure system in super high-rise buildings
