Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for constructing a high-rise cylindrical structure such as a free-standing chimney or tower.

(Prior art) Conventionally, when constructing a self-supporting steel chimney, as shown in Fig. 13, the cylinder blocks (b)'r are lifted one by one using a large truck crane (α), and the existing chimney portion is (It was installed on the CL and completed by welding, painting, etc.

(Problems to be Solved by the Invention) However, even the largest version of truck fliers has a lifting height of about 1 oom, making it impossible to construct a super high-rise free-standing chimney exceeding 1 ooom. Additionally, super-large truck cranes are subject to space constraints at construction sites, making construction work on narrow sites impossible.

In addition, since the cylinder block is suspended by wire, the pendulum phenomenon requires a specialist craftsman to install and position it in the air, which tends to pose problems in terms of work safety and efficiency, and furthermore, work in strong winds is difficult. It becomes difficult.

(Means for solving the problem) The present invention has been proposed to solve the problem as described above, and is constructed by building a high-rise structure by sequentially stacking all the blocks divided into multiple blocks in the height direction from the lower side. In the construction method, a lifting rail is sequentially installed along the side wall of the completed part, and a self-propelled mobile truck with a crane mounted on the rail is attached to the above-ground part. A hanging lobe is stretched from the winch via the crane, and the block connected to the tip of the lobe is lifted up, and the blocks are stacked on top of the existing part of the high-rise structure using the front raising wren, and the high-rise structure is constructed. This relates to a method for constructing a high-rise structure, which is characterized by the construction of high-rise structures.

(Function) As described above, in the present invention, when a high-rise structure is constructed by stacking blocks divided into a plurality of blocks in the height direction sequentially from the lower side, the side wall of the existing part after construction is completed. Rails for raising and lowering were installed in sequence along the rails, and a self-propelled crane truck carrying a crane was mounted on the rails so that it could be raised and lowered, and the crane was lifted from a winch on the ground. The block is connected to the tip of a hanging lobe stretched through the crane, and by operating the winch, the block is hoisted to the crane via the lifting lobe, and then the winch is fully activated and the block is hoisted to the crane. All the blocks suspended via lobes are stacked on top of the existing part of the high-rise structure and connected to the same existing part, and the same steps as described above are then repeated to construct the high-rise structure.

(Effects of the Invention) According to the present invention, the system can run on rails that are sequentially installed along the outer wall of the existing part of a high-rise structure that has been erected, without using a crane truck as in the past. The blocks are piled up and erected on top of the existing part of the high-rise structure by a continuous attack between a crane-containing vehicle loaded with crane and a winch installed on the ground. This makes it possible to erect high-rise structures even on narrow sites, and the drive mechanism and power source for lifting the heavy blocks are installed on the ground, making aerial equipment simpler, smaller, and lighter. Furthermore, since the block is slid on the side wall surface of the structure, the crane can be made smaller and lighter, and work can be performed in strong winds.

Furthermore, since the crane puller is self-propelled and the length of the winch lobe can be set arbitrarily, there is no height restriction when constructing the super high-rise structure Q. Further, since the crane truck lifts the blocks in a stationary state, it can withstand a large load even though it is small.

(Example) The illustrated example in which the present invention is applied to the erection of a self-supporting chimney will be described below.
