Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tower-like structure erection device, and is useful when applied to the work of erection of various tower-like structures such as a high-rise chimney with an exterior plate and a large-diameter high-rise chimney.

[0002]

2. Description of the Related Art A conventional construction method for a high-rise stack with an exterior plate will be described with reference to FIG. The chimney shown in FIG. 5 is called an aesthetic type chimney because an appropriate number of inner cylinders 03 are covered with outer plates such as outer cylinders 04, and will be referred to as such. Each inner cylinder 03 is composed of a plurality of inner cylinder blocks 03a, and the outer cylinder 04 is composed of a plurality of divided blocks 04a. Various beam members 05 are used as appropriate. At the time of erection, first, a certain inner cylinder 03 is built up to a certain height by a not-shown chloraculene, and a post-crane 01 is installed on the top of this inner cylinder 03, and then this inner cylinder 03 with post-crane is installed. It is lifted by a jack-up device (not shown), and the inner cylinder block 03a carried by the carriage 02 is inserted into the gap. By sequentially repeating the insertion of the inner cylinder block 03a, the post-cleaning inner cylinder 03 is installed in advance. Next, Post Cren 0
1, the divided blocks 04a of the outer cylinder 04 are hoisted and sequentially mounted, and similarly, the inner cylinder block 03a is also hoisted and sequentially mounted and built for other adjacent inner cylinders 03. 05 will be lifted and built sequentially.

[0003]

However, as described above, in the conventional construction method, all the members 03 such as a plurality of inner cylinders, outer cylinders and various beam members are made by one post-crane 01.
Since a, 04a, and 05 are sequentially lifted one by one to build, and parallel work cannot be performed, the efficiency of the erection work is poor, and a large number of man-hours and work periods are required. In addition, the post cylinder 01 uses the inner cylinder block 03a,
When a structural block such as the divided block 04a of the outer cylinder is hoisted, there is a problem that swaying occurs due to wind or the like. In addition, since the work area is exposed to rain during rainy weather, the erection work cannot be performed and the operation rate is reduced. The present invention aims to solve the above-mentioned problems.

[0004]

In order to achieve the above object, a tower structure erection device of the present invention comprises a lifting mechanism that raises along an existing part of a tower structure by using the existing part of the tower structure as a scaffold. A scaffolding mechanism having one or more working scaffolds on which beam members arranged in each layer of the tower-like structure are supported by the lifting mechanism, and a roof supported by the lifting mechanism and covering the existing portion A crane for hoisting a structural block of the tower-like structure, further comprising a circular rail laid inside the roof, an outer frame rotatably suspended on the annular rail, and an outer frame. It is characterized by comprising an inner frame installed so as to be able to reciprocate, and a hoist installed so as to be able to travel in this inner frame. Further, a horizontal beam support mechanism is provided below the scaffold mechanism to support a set of horizontal beams arranged in each layer of the tower-shaped structure in a multi-tiered manner. Further, the present invention is characterized in that it is provided with a shake prevention mechanism for suppressing the shake of the structural block suspended on the crane.

[0005]

According to the above-mentioned tower structure erection device, the scaffolding mechanism, the roof and the crane are lifted along the existing portion of the tower structure by the lifting mechanism. In Clen, the structural block is hoisted by the trolley hoist, and the structural block is positioned by the traveling of the trolley hoist, the reciprocating movement of the inner frame, and the turning of the outer frame. On the other hand, the beam members of each layer of the tower-like structure are mounted on the scaffolding mechanism via, for example, the horizontal beam supporting mechanism, and are lifted together with the scaffolding mechanism by the lifting mechanism. Therefore, the suspended structural blocks can be sequentially mounted and built on the work scaffold of the scaffolding mechanism, and the beam members can be sequentially mounted on the work scaffolding as the scaffolding mechanism rises, enabling parallel work. Further, since the erection work area is covered by the roof, rainwater or the like is prevented from entering when raining. Therefore, all-weather erection work is realized. Further, since the structural block is lifted, there is a shaking prevention mechanism, so that the structure does not shake even if it receives wind or the like.

For example, the inner cylinder block 3 as a structural block
When hoisting a, the inner frame 16 is moved to the left and the front side thereof is projected to the outside of the outer frame 15. Similarly, after the trolley hoist 17 is run to the left, the wire 17a of the trolley hoist 17 is moved. It is wound down, and the inner cylinder block 3a on the ground is lifted up via the hook 18 so as to avoid the existing structure. After the inner cylinder block 3a is lifted to a predetermined height, the inner frame 16 is moved to the right next to the outer frame 15.

Next, the outer frame 15 is turned along the circular rail 19 and the trolley hoist 17 is moved to position the structural block 3a being lifted. Then, the scaffolding mechanism 11 is constructed using the upper or lower work scaffolds 11a and 11b.

When the structural block is the outer cylinder divided block 4a, the hoisting position is set to the roof 1 as shown in FIG.
Positions in each direction (a), (b), avoiding the support pillar 6 of 3
(C) and (d), the size of the divided block 4a is divided into four blocks in the circumferential direction of the outer cylinder 4. For example, when the divided block 4a is lifted from the position in the (b) direction, the outer frame 1
After turning 5 to the same (b) direction position, the inner frame 16 is projected to the outside of the outer frame 15 and the trolley hoist 17 is driven to lift the divided block 4a on the ground to a predetermined height in the same procedure as described above. After that, the trolley hoist 17 is run to draw the divided block 4a inward of the outer frame 15, and is positioned and installed. By repeating this operation also at the other positions (a), (c), and (d), the assembling of the divided blocks 4a on the entire circumference of the outer cylinder is completed.

Thus, as the construction of the structural blocks 3a, 4a progresses, the telescopic jack 14 of the lifting mechanism 1 is driven to sequentially jack up the roof 13 and the scaffolding mechanism 11. In response to this, Shuttle Crane 2 rises,
Using this, follow the steps described above for building block 3
a and 4a are sequentially lifted, positioned, and mounted on an existing part to build. By repeating this work for each layer, the work of constructing the structural block can be efficiently performed.

On the other hand, the lower working scaffold 11b of the scaffold mechanism 11

Further, when the structural blocks 3a, 4a of the inner and outer cylinders are lifted, the guide rails 25 are provided along the existing outer cylinder 4 as a shaking prevention mechanism, so that the structural blocks 3a, 4a being lifted are guided. The shaking of the structural blocks 3a, 4a is suppressed to a minimum. For example, a slidable guide may be fitted to the guide rail 25, and the guide rail 25 may be attached to the structural block to be lifted by a wire. Furthermore, since the entire erection work area is always covered by the roof 13, rainwater, etc. do not fall,
Work can be continued regardless of the weather.
