Construction method of fully enclosed layer in core tube of super high-rise building

Abstract

The invention provides a construction method of a totally closed layer in a super high-rise building core cylinder. The construction method comprises the steps that in the construction process of thesuper high-rise building core cylinder, when a core cylinder vertical wall exceeds an external frame steel structure by a plurality of storeys, and the external frame steel structure exceeds an internal cylinder horizontal structure by a plurality of storeys, the two ends of a first high altitude gallery are arranged on a first connecting beam and a second connecting beam of the core cylinder vertical wall correspondingly, and the first connecting beam and the second connecting beam are opposite to each other. A first cross beam and a second cross beam are transversely arranged on the left side and the right side of the first high altitude gallery correspondingly, and the first cross beam and the second cross beam are connected with the first high altitude gallery and the core cylinder vertical wall correspondingly. The first cross beam and the second cross beam are paved with a plurality of first face plates correspondingly. The construction method is ingenious in design, easy, convenient and rapid to operate, and low in cost. The constructed totally closed layer can bear large loads, the requirement for force bearing of a vertical steel pipe formwork is met, an up-down perpendicular operation face is provided, an internal cylinder can be divided to two construction sections to be constructed independently up and down, the construction safety is ensured, the construction period pressure is relieved, and the construction method is suitable for being applied and promoted in a large scale.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to the technical field of super high-rise building core tube construction, and specifically refers to a construction method for a fully enclosed layer in a super high-rise building core tube. Background technique [0002] Super high-rise buildings refer to buildings with more than 40 floors and a height of more than 100 meters. China's "General Rules for Civil Building Design" GB50352-2005 stipulates that when the building height exceeds 100m, both residential and public buildings are super high-rise buildings. [0003] The formwork system is generally used for the construction of the vertical wall structure during the construction of the core tube of a super high-rise building. Generally, the outer frame steel structure lags behind the vertical wall by 10 to 15 floors, and the outer frame concrete structure lags behind the outer frame steel structure by 5~ 10 floors,...

Problems solved by technology

[0003] The formwork system is generally used for the construction of the vertical wall structure during the construction of the core tube of a super high-rise building. Generally, the outer frame steel structure lags behind the vertical wall by 10 to 15 floors, and the outer frame concrete structure lags behind the outer frame steel structure by 5~ 10 floors, the horizontal structure of the inner cylinder is 5 floors behind the outer frame concrete structure or 10-15 floors behind the outer frame steel structure, so the safety requirements for vertical operations are high, and the construction period is delayed.
