多人数の人手を要し、作業能率が悪い欠点があった。2. Description of the Related Art In a conventional tower mast for construction of a tower, when a tower top is constructed or dismantled,
A push-up type lift-up device (climbing device) is installed outside the tower, and the base of the boom is pivotally mounted on the upper support of the tower mast, and the tower member suspended at the tip of the boom is placed around the tower mast. The assembled or assembled tower member can be disassembled (Japanese Patent Laid-Open No. 5-2866).
No. 94). However, even when attempting to assemble the triangular pyramid tower at the top of the tower, the boom hinders the movement of the center of the triangular pyramid tower to the center of the tower and cannot be stacked. In addition, it is difficult to remove the triangular pyramid tower section of the tower assembled on the ground without dismantling it, and it is necessary to suspend the top of the boom to disassemble and assemble or dismantle the top of the triangular pyramid tower. The bolts and nuts must be loosened to dismantle the triangular pyramid tower from the steel tower, and the disassembled members must be processed and processed, and the assembly and disassembly work requires a long time and a large number of people, There was a drawback that work efficiency was poor.

By installing an auxiliary boom that has its base fixed to the part vertically and can be tilted forward, a tower mast is arranged at the center of the tower, and the triangular pyramid tower member of the tower is installed with the auxiliary boom. The triangular pyramid-shaped tower member placed and fixed on the upper end of the tower or fixed on the upper end of the tower can be pulled down from the upper end of the tower with the auxiliary boom and disassembled from the tower. It is what was constituted.

It is possible to assemble a steel tower by raising and raising a crane drive device inside, storing the drive device of the crane in the tower mast, assembling the tower mast in a small steel tower, and disassembling. The tower can be assembled at the same time.

きる。As described above, according to the present invention, by installing a tower mast inside a tower, the tower and the tower mast can be assembled or constructed simultaneously or at different times.
The boom attached to the upper end of the tower mast is tilted backward from the center axis of the tower, and the auxiliary boom attached to the tip of the boom is tilted forward and the hook of the wire rope suspended from the tip is attached to the center of the tower. It is guided in the axial direction and locked at the top of the triangular pyramid-shaped tower, and the wire rope is pulled down or pulled up by a crane drive to lock the top of the triangular pyramid at the top of the tower, or the top of the tower. Boom 2 when removing from
However, the work process can be simplified without disturbing, and the assembling and disassembling of the tower and the top of the triangular pyramid tower can be performed quickly.
Also, when the boom is in the upright state, the plane dimensions are equal to or smaller than the tower mast, so if there is a gap in the tower at the time of the descent, the tower can be dismantled. Therefore, it is possible to assemble and disassemble a small tower, and it is possible to pass through the small tower because the driving device of the crane is housed in the tower mast.
