Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a working scaffold structure for a waterside structure and a mechanism for moving the scaffold structure, and a stabilizing structure for repairing or cleaning the bottom and lower surfaces of the structure such as above water. The present invention provides a scaffold structure that is easy to handle and an operation mechanism for performing a moving operation thereof, and performs an upward operation on water or the like as described above stably and accurately, and also appropriately and easily moves and sets a considerable area. The purpose of the present invention is to make it possible to carry out a smooth operation efficiently with a relatively compact facility in a work area having the above.

[0002]

2. Description of the Related Art The use of scaffolds in performing various operations on water structures has been conventionally employed in various ways,
Although it has just been implemented, it is not always easy to set the scaffold stably for the target structure etc. because it is work on water, and it requires considerable man-hours and time, and it is particularly stable In order to obtain a proper mounting, many man-hours are required for setting or moving.

[0003] In the case of work on the side wall surface for setting the scaffold, it is possible to adopt a hanging method from the roof or the upper floor, but a scaffold for performing the work on the lower surface of the water body structure or the bottom of the deck. It is generally difficult to find an appropriate support portion, and a special setting portion is generally formed.

[0004]

In any of the above-mentioned prior arts, it is difficult to stably set a scaffold for a waterside structure, and in particular, the bottom surface of a structure formed on the water surface is difficult. Under such conditions, special processing and work for setting a scaffold, such as providing a special setting section, are required, which is accompanied by a significant disadvantage. Scaffolds that are temporarily set generally lack stability, and those that increase this stability have to increase the number of steps of setting or moving operations.

As described above, the special processing or work for setting the scaffolding on the lower surface of the floating structure or the bottom surface of the deck greatly impairs the use or appearance of the structure, and such processing for cleaning or repairing, It is also generally known that constructions cause significant disadvantages and deformations to buildings. In addition, since it is difficult to move or relocate, it often serves as a scaffold for the entire object.

In the case of a floating structure, there is a danger that an operator or the like may fall into the water. Therefore, careful setting is required when setting the scaffold. It is complicated because it requires fixed support materials, etc.In some cases, it requires in-water workers wearing diving clothes, so work efficiency is inferior, and work costs must be considerably increased . Of course, the risk is also high.

Immobilization by the wire 5 after moving to the target position can also be accurately achieved with relatively few operations. It should be noted that the buoyancy member 7 is shown in FIG.
As shown in FIGS. 1 and 12, a large number of the buoyancy members 7 may be used, but approximately four may be provided by adopting a large-sized body. It can be streamlined.

As shown in the drawing, the buoyancy section 7 can adopt a foamed resin molded article as shown in FIG. 13 and can give a sufficient buoyancy. By arranging a plurality of connecting portions 8 as shown in FIG. 13 on the buoyancy portion of the body, an appropriate cord or other connecting member is used, and as shown in FIGS. It can be properly mounted and arranged on the bottom,
A favorable balance may be provided to provide buoyancy. That is, the scaffold 1 as described above can be moved to an appropriate position using buoyancy on the water surface even if the scaffold 1 is reasonably large (to the extent that a worker can get on and work).

In the case where it is desirable to obtain buoyancy even in the air, the buoyancy portion 7 can be similarly implemented by utilizing the buoyancy by employing a balloon-like portion filled with a lightweight gas. It should be noted that even when the buoyancy is obtained in such air and the scaffold 1 is levitated, a stable material such as a spacing material is disposed on the scaffold and a certain gap is provided between the scaffold 1 and a structure to be worked. Get the settings.
