Slant-leg rigid-frame-type supporting structure of super-high-rise building mega-frame bottom layer and construction method

Abstract

The invention discloses a slant-leg rigid-frame-type supporting structure of a super-high-rise building mega-frame bottom layer. The slant-leg rigid-frame-type supporting structure of the super-high-rise building mega-frame bottom layer comprises mega-frame columns, a slant-leg rigid-frame-type supporting structure body, cross-supporting structures, annular belt truss beams and a sub-frame structure. The slant-leg rigid-frame-type supporting structure body is arranged between the two mega-frame columns, and the slant-leg rigid-frame-type supporting structure body is composed of two rigid-frameslant-leg columns and a rigid-frame horizontal beam. The lower ends of the rigid-frame slant-leg columns are separately connected with the two mega-frame columns, and the upper ends of the rigid-frame slant-leg columns are connected with the rigid-frame horizontal beam. The upper ends of the rigid-frame slant-leg columns extend upward and are connected with the cross-supporting structures, the upper ends of the cross-supporting structures are connected with the two mega-frame columns, the annular belt truss beams are arranged at the upper ends of the cross-supporting structures, the other cross-supporting structures are connected to the upper parts of the annular belt truss beams, and the annular belt truss beams and the cross-supporting structures are repeatedly arranged alternately upwards. The slant-leg rigid-frame-type supporting structure of the super-high-rise building mega-frame bottom layer has the advantages of large lateral rigidity, good seismic performance and the like.

Description

technical field [0001] The invention belongs to the technical field of supporting structures of giant frames, and in particular relates to a support structure of oblique-leg rigid frame at the bottom of a giant frame of a super high-rise building. Background technique [0002] With the development of super high-rise building structures, the structural system of super high-rise buildings is becoming more and more complex, and the use of obliquely braced giant frame structure systems is becoming more and more extensive. [0003] In actual engineering, the entrance to the ground floor of a giant frame super high-rise building often requires a hollow hall with a height of 3 to 4 floors. The entrance of a super high-rise building requires a tall and spacious building to ensure that people will not feel oppressed when entering the super high-rise building. How to take into account the coordination of the conversion girders of the ground floor hollow hall, the anti-seismic structur...

AI Technical Summary

Problems solved by technology

[0004] Under the conversion girder of the existing ground floor hollow hall, there is a design of herringbone support, which can meet the requirements of architectural aesthetics. However, the matching between the ground floor herringbone support and the upper X cross support is poor; the existing ground floor hollow hall conversion girder The bottom is designed in the form of V-shaped support. The V-shaped support on the bottom layer matches the X-cross support above. However, the aesthetic effect of the architectural appearance is not good, and it affects the use of the lobby on the ground floor.
