In each of FIGS. 4 to 8, the guide rail side is shown on the left side of the figure and the fixed frame side is shown on the right side of the figure for easy understanding.

Step 1 (FIG. 4): A step of removing the guide rail 5 is shown. Confirm that the fixed frame 13 is fixed to the wall 1 and that the upper rod 9a of the upper lock cylinder 9 is completely inserted into the lock hole 5b of the guide rail 5. The anchor bolts that fix the guide rails 5 on the side of the climbing unit 7 attached to the upper scaffolding unit 2 and the lower scaffolding unit 3 to the wall 1 are removed.

Step 6 (FIG. 9): The whole ascending process centered on the upper and lower scaffolding units 2 and 3 is shown. The lower lock cylinder 10 is operated and extended to lock the lower rod 10a in the lock hole 5b. The upper lock cylinder 9 is operated and contracted (in this step, the upper rod 9a can be automatically removed by slightly operating the climbing cylinder 7). Operate the climbing cylinder 7 to extend it. The whole of the upper and lower scaffolding units 2, 3 rises. This climbing operation is repeated up to the desired height. The fixed frame 13 is pressed against the wall 1 by operating the upper slide cylinder 14 and the lower slide cylinder 14a. Anchor bolts for fixing the fixed frame 13 are attached.

Through such steps, the scaffolding unit can be raised. It should be noted that although the description about the descending is omitted, it can be performed by the reverse process to the above.

In the above embodiment, the scaffolding unit is described, and the outer scaffolding is not illustrated.

It can be configured and implemented in a corresponding relationship with the scaffolding unit during work.

Further, in the cross section in FIG. 3, the tower-shaped structure has an octagonal cross section, and the scaffolding unit also has an octagonal shape. However, it may be appropriately set according to the cross-sectional shape of the tower-shaped building to be constructed. For example, when constructing a building with a substantially rectangular cross section, the scaffolding unit should be a quadrangle, the formwork should be formed,
A concrete structure may be constructed by placing concrete in the formwork and curing it to form a wall, and then constructing a rectangular columnar structure.

Further, as seen in FIG. 1, in this embodiment, the difference in the height direction between the upper scaffolding unit 2 and the lower scaffolding unit 3 is about 2 units with respect to the building unit of the wall 1 shown on the left side. The length of the guide rail 5 was also set to about 3 units, but this is a construction process, in which the lowest wall unit has completed curing and the formwork has been removed, and the next unit is being cured with a frame, The above-mentioned condition is taken into consideration in the progressing state that concrete is being poured, and the dimensional relationship between them is not limited to this example.

[0032]

As described above, according to the present invention, a climbing unit and a fixed unit are provided in a scaffolding unit, and by utilizing both of them in a predetermined process sequence, the scaffolding unit is moved up to make a tower-like structure. Since the formwork was moved sequentially so that the walls would be continuous in the construction direction of the object, the method used to assemble the entire scaffold, which is conventionally used, and considerable strength are required. It does not require a tower mast, which is very laborious and costly. Therefore, there is a great effect that both cost and working time can be saved.

Further, since the driving operation of each part in each step is performed by the cylinder, the fatigue of the operator is small and the work is highly safe.
