  Next, the function and effect of the scaffold 2 having the above configuration will be described. The column material 5 constituting the column 3 of the scaffold 2 extends continuously from the first member 5a when the second member 5b is pulled out from the first member 5a formed in a cylindrical shape, The three members 5c are continuously extended from the second member 5b by being pulled out from the second member 5b formed in a cylindrical shape. In this way, the length of the support material 5 and by extension the support material 3 is ensured. And the support | pillar 3 is connected by the some connection material 4 and 4, and the scaffold 2 is formed. Here, the column member 5 is before the second member 5b is pulled out from the first member 5a and before the third member 5c is pulled out from the second member 5b, that is, the column member 5 is stretched. Before the second member 5b, the second member 5b is accommodated in the first member 5a, and the third member 5c is accommodated in the second member 5b. In this way, the column material 5 is made compact, so that the column material 5 and eventually the disassembled scaffold 2 can be handled easily. Then, the column member 5 can be assembled by pulling out the second member 5b from the first member 5a and pulling out the third member 5c from the second member 5b, that is, by extending the column member 5. It is possible to assemble the support material 5 and the scaffold 2 easily.

In this way, in addition to the first adjustment fixing means 8 and the second adjustment fixing means, the height adjustment width of the scaffold 2 is increased by connecting the support material 18 to the support material 5 according to the situation. Can do.

  Further, the column member 5 is prevented from being pulled out of the first member 5a by the first retaining means 10 and the second retaining means, and the third member 5c is The escape from the member 5b is prevented. Therefore, the 1st member 5a and the 2nd member 5b do not separate, and the 2nd member 5b and the 3rd member 5c do not separate, and handling becomes still easier. Furthermore, by providing the 1st connection tool 12, the 2nd connection tool 13, and the 3rd connection tool 14 which connect the connection material 4 to the 1st member 5a, the 2nd member 5b, and the 3rd member 5c. The support members 5, 5 and thus the support members 3, 3 are easily connected.

  Further, since the work can be sequentially performed by rotating the wheel 20a provided in the scaffold 2 and moving the scaffold 2, it is possible to cope with the small-scale scaffold 2. Moreover, since the wheel 20a is rotated by the prime mover 20b, the scaffold 2 can be easily moved. In addition, the direction of the wheel 20a is changed with a simple structure called a link mechanism. Thus, the scaffold 2 can be easily moved in a required direction by changing the direction of the wheel 20a. In the illustrated embodiment, the scaffold 2 is arranged so as to cover a radial portion of the tank 1 in the radial direction. And the work of the whole tank 1 can be performed by moving this scaffold 2 sequentially in the circumferential direction of the tank 1.

For example, the column member 5 is provided with a pair of a second member 5b and a third member 5c in addition to the first member 5a, which are drawn out upward and downward. Each of the three members 5c may be provided and pulled out only to one of the upper side and the lower side. As described above, the support member 5 includes the first member 5a, the second member 5b, and the third member 5c, and is formed to be extendable / contractable. The member 5a and the second member 5b may be formed to be stretchable. On the other hand, in addition to the first to third members 5a, 5b, and 5c, the column member 5 is a fourth member that is pulled out from the third member 5c so as to extend further continuously from the third member 5c. And may be formed to be stretchable.

  Moreover, although the wheel 20a and the motor | power_engine 20b are provided as the moving means 20 of the scaffold 2, the motor | power_engine 20b does not need to be provided only by the wheel 20a. Further, the scaffold 2 may be a fixed scaffold without the moving means 20 being provided. Further, even if the wheel 20a is not directly placed on the bottom plate 1c, for example, a rail may be placed on the bottom plate 1c, and the wheel 20a may rotate and move on the rail.

  Further, the scaffold 2 may be used not only for the construction inside the tank 1 but also for the outside construction. Furthermore, the scaffold 2 may be used for construction of the tank 1, even if it is not used for repair work or repair work of the tank 1. And a structure is not limited to the tank 1, Other structures, such as a bridge and a building, may be sufficient.
