Background
The hoisting of the building dome structure is an important part in the building engineering, and is also one of the parts with higher difficulty and requirements in the building construction process, and is directly related to the progress of the engineering, the quality of the building and the construction cost.
In recent years, as large buildings are built more and larger, building dome structures are more and more complex, and the hoisting difficulty is higher and more, on the contrary, the construction period is shorter and higher, and the quality requirement is higher and higher, in particular, the mechanical equipment and the construction conditions and the construction period required by building construction never meet the imagination of designers and requirements of owners, so that the hoisting of the building dome structures is always a major problem for builders.
For example, with the increase of environmental requirements, small cement plants are eliminated, while the devices and equipment of large cement plants are usually large, the matched buildings are also large, and production and transportation equipment is usually required to be installed inside and on the top of the buildings, the dome structure is very complex, and therefore, the difficulty in hoisting the dome structure becomes very difficult.
Some huge cement manufacturing enterprises producing ten thousand tons per day need to be matched with and build a plurality of hundred thousand-ton-level clinker warehouses, the clinker warehouses are very huge, the height of an outer wall of each clinker warehouse from the bottom to the top reaches 40m, a dome adopts an all-steel truss structure, the all-steel truss structure consists of an upper ring beam and a lower top frame and is an inverted bowl-shaped structure, the overall weight of the dome structure exceeds 300 tons, the diameter reaches 50m, and the height reaches 17 m.
In the prior similar building with similar shape and smaller volume, a dome structure is generally constructed by adopting a method of ground assembly and integral hoisting by using a crane, but the weight of the dome structure of a hundred thousand-ton-level clinker silo is 300 tons, so that the dome structure with the weight is hoisted by using a 1200-ton crawler crane, the renting cost of the large crane is extremely high, and the time required for early preparation and reservation is extremely long, so that the traditional hoisting scheme does not accord with the principles of high efficiency, safety and economy.
Of course, there are many hoisting methods worth referring to in the prior art, such as:

the invention discloses a lifting method of a top ring in dome structure installation (application number 201210221120.5), which comprises the steps of correctly selecting a proper crane and a proper lifting appliance, lifting and arranging a temporary steel bracket of the top ring, arranging a steel wire rope on the temporary steel bracket to serve as a wind-holding rope for stabilizing the temporary steel bracket before the top ring is in place, configuring a 2t inverted chain as a tensioning device for each wind-holding rope, and determining the type and the model of the crane according to the weight, the maximum diameter, the height of a body and the installation height of the top ring;
the invention discloses a hoisting method of a large-span asymmetric rectangular space twisted pipe truss (application number 201210460439.3). the method can place the asymmetric rectangular space twisted pipe truss in one step when being installed at high altitude, and ensures that the whole installation work is simple and practical, the construction period can be greatly shortened, and the construction cost is reduced;
the invention discloses a special lifting appliance and a lifting method for a steel containment vessel head of a nuclear island of a nuclear power station, which are disclosed by the patent application number 201210177992.6, and can ensure that the deformation of the head in the lifting process is reduced to the minimum, thereby meeting the lifting requirements of large components and equipment of the nuclear power station;
the invention discloses a roof truss hoisting method disclosed in the patent application (application number 201910693610.7), which effectively solves the problems that a construction area is limited, large-scale hoisting equipment cannot be used, an operation field is narrow, and conventional hoisting operation is difficult by reasonably planning a limited operation space and scientifically formulating a hoisting process.
In spite of the above prior art, the problems encountered in the prior art can be solved, but no construction scheme is provided for efficiently, safely and inexpensively completing the hoisting of a building, particularly a large building dome structure under the difficult conditions of no large hoisting equipment, short construction period, complex dome structure and the like, and no clear and direct suggestion is provided.
