[0002]

2. Description of the Related Art Conventionally, when constructing a high-rise structure such as an office building, a tower crane is arranged on the ground where the structure is to be constructed, and the tower crane is used first for the first floor. The first layer is constructed by suspending the columns, beams, floors, walls, and the like previously manufactured at the factory for constructing the first structure, and assembling them sequentially, and then the structure of the first layer A tower crane is transferred to the upper part of the object to construct a second-layer structure, and the above operation is repeated until the number of layers reaches a desired number. When the floor area of the constructed structure is large, the construction work is performed by arranging a plurality of tower cranes in parallel.

[0003]

However, in the above-described conventional method of constructing a high-rise structure, since the structure is constructed mainly by a tower crane, various precast members constituting each story are formed. When assembling,
It requires a lot of labor such as a carpenter and an operator for a tower crane, which increases the operating cost, lowers the productivity of construction, and is far from unmanned construction. In addition, as the height of the tower crane from the ground rises as the height of the tower crane increases, the length of the wire rope that suspends the precast member increases, and the suspended precast member and the boom are blown by the wind. In addition to swinging and causing danger, the tower crane must be replaced as the building level rises, which makes the setup replacement work complicated, and the actual construction work cannot be performed at the time of setup replacement. There's a problem. Furthermore, the tower crane has a blind spot, so its working range is narrow,
Being able to cover the entire working range of the structure
There was a problem that the number of tower cranes increased.

[0004] The present invention has been made in view of the above-described circumstances, and aims to improve the efficiency of construction and construction of a structure.
It is an object of the present invention to provide a method of constructing a structure that facilitates unmanned operation, secures a wide working range without blind spots, and enables construction work that is not affected by weather.
