Embodiment Construction
[0018] The present invention will be further described below in conjunction with embodiment:
[0019] A method for constructing a horizontal structure of a super high-rise building core tube, characterized in that it comprises the following steps:
[0020] S1: Construction layout, segmental construction technology of core tube horizontal structure, super high-rise building structure using top formwork or climbing formwork system construction, when the core tube wall is constructed to the standard floor n floor along with the top formwork, according to the construction layout and Structural characteristics, choose the steel beam and profiled steel composite structure designed in depth to replace the original n-m layer concrete horizontal structure, and use this layer as a supporting platform to erect the n-m+1 layer horizontal structure formwork frame; when the core tube wall When the top formwork construction reaches the standard floor n+m floor, the steel beam and profiled st...

The invention discloses a construction method for a horizontal structure of a core wall of a super high-rise building. The construction method is characterized by comprising the steps of (1) construction arrangement, (2) installing construction of steel members and embedded components, (3) installing construction of machines and tools, (4) construction of profiled steel sheets, (5) construction of horizontal and solid protection, and (6) construction of horizontal structure slabs. When top die or creeping formwork is adopted in the construction of the super high-rise building, the construction method for a horizontal structure of a core wall of a super high-rise building can divide the horizontal structure into different construction segments according to floors and areas and then conduct construction, which greatly quickens the construction speed; meanwhile, in order to conduct the construction of the towering segment of the horizontal structure, a combined structure of steel beams and the profiled steel sheets is adopted to replace a concrete structure, and the adjusted combined structure can serve as a support platform of the construction of the upper portion of the horizontal structure and a protective shed for lower floors. After the above technical scheme is adopted, the construction of the horizontal structure is quickened, the structure rigidity is reinforced, and the whole force of the structure is improved; moreover, through the disposition of measuring and controlling points on each floor of the horizontal structure, the difficulty of measuring work is greatly reduced, and the measuring precision is guaranteed.
Description
technical field [0001] The invention belongs to the field of construction, and in particular relates to a construction method for a horizontal structure of a super high-rise building core tube. Background technique [0002] With the development of the city, the population is increasing, and the land is becoming less and less, super high-rise buildings (that is, buildings with a height greater than 100m) are constantly emerging. Super high-rise buildings are mostly designed as a frame core tube structure. The core tube is mainly constructed by climbing formwork or top formwork. It is suitable for the vertical structure of the core tube to be constructed first, and the horizontal structure is lagging behind, and the construction speed is slower than that of the vertical structure. The core wall is constructed first, and if the construction after the horizontal structure is not inserted in time, the height difference between the core wall and the horizontal structure will becom...
