Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing, and the structure and principle of this device are very clear to those skilled in the art. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] Now take the drafting of a project as an example to illustrate. The main building parameters of the example are: the main building has 60 floors above ground, 4 floors underground, the total building height is 280 meters, and the total construction area is about 180,000 square meters. The main building adopts an outer frame and inner tube structure system. The plane of the core tube is octagonal, which is a reinforced concrete structure, and steel columns are inserted inside; the outer frame is hexagonal, and the outer frame columns are steel concrete columns, and the outer frame floor is steel beams. , Composite floor slab of ...

Abstract

The invention relates to the technical field of engineering construction, in particular to a tower crane construction technology used for a super high-rise building steel structure. The tower crane construction technology used for the super high-rise building steel structure comprises the following steps: a) carrying out tower crane model selection and tower crane plane arrangement; b) carrying out tower crane climbing analysis which comprises the structure setting of a tower crane climbing system and climbing elevation determination; c) carrying out tower crane climbing; d) calculating the internal force and the displacement of a core tube shear wall structure which bears tower crane load and creeping formwork load. Compared with the prior art, the tower crane construction technology has the advantages of reasonable process design and high actionability; according to repeated experiments, the tower crane construction technology is strictly executed according to a working condition set in a scheme, and the deformation of the core tube shear wall is within an allowable range of a standard through multiple times of practical observation. Practice proves that the function configuration and the plane arrangement of the construction engineering of a high-rise steel structure and a large tower crane are reasonable; the design of a climbing system and a climbing technology are advanced and proper; calculation relevant to the tower crane load is correct, and the whole working state of the tower crane is safe and reliable.

Description

[technical field] [0001] The invention relates to the technical field of engineering construction, in particular to a tower crane construction process for super high-rise building steel structures. [Background technique] [0002] Tower crane is the most commonly used type of lifting equipment on construction sites, used to lift steel bars, corrugated wood, concrete, steel pipes and other construction materials for construction. The tower crane is an essential equipment on the construction site, and it is also the core equipment for the construction of super high-rise steel structures. Its reasonable selection plays a key role in the progress of the construction. [0003] However, there are many deficiencies in the tower crane process in the prior art, and the imperfection of the process directly or indirectly leads to problems in the efficiency, quality and cost of the project. [Content of the invention] [0004] The purpose of the present invention is to solve the defici...
