A two-way synchronous construction method for high-rise buildings

Abstract

The invention relates to a two-way synchronous construction method for high-rise buildings, which belongs to the technical field of building construction. In the method, the steel column at the shear wall of the core tube is encrypted to form an encrypted steel column, and the cast-in-place pile below the encrypted steel column is also encrypted to form a steel column, a horizontal structure of the B0 layer, a horizontal structure of the B1 layer, and a B1 layer. The box load-bearing structure of the core tube of the first floor, the box load-bearing structure has better integrity and greater rigidity, and can smoothly transfer the stress of the above-ground structure to the steel columns and cast-in-place piles below, preventing local pile foundations from The problem of uneven settlement caused by high stress ensures the simultaneous construction of the upper structure during the construction of the basement. In addition, the present invention takes the lead in completing the construction of the basement encrypted steel column. After the basement floor is poured, the shear wall of the basement core tube is constructed using the sequential method, which solves the problem that the shear wall cannot be reversed, and realizes the connection between the encrypted steel column and the underground core. Tube shear wall conversion.

Description

technical field [0001] The invention relates to a two-way synchronous construction method for a high-rise building, in particular to a two-way synchronous construction method for a basement of a high-rise building and an above-ground core tube, and belongs to the technical field of building construction. Background technique [0002] The reverse method can solve the safety problem of foundation pit operation in urban high-rise dense areas, shorten the construction period, reduce the construction temporary support cost and maximize the economic benefits of the unit of land. It is more and more widely used in construction. The core concept of the upside-down method is that the basement of each layer below the ground adopts a top-down construction sequence, and the basement floor structure and vertical support structure form a horizontal stiffness to support the foundation pit and ensure the safety of the excavation of the foundation pit. [0003] However, the basements of high...

Problems solved by technology

[0003] However, the basement of high-rise and super-high-rise structures includes many floors, and the construction period of the underground structure is relatively long. If the basement is completed and then the structure above the ground is constructed, the construction period of the building will be affected.
