In general, a ship's chieftain (scaffolding) structure means that when the ship is to be dried, when the welding or painting area is located at a high place, the worker must stand on the chieftain board and work on the inner wall of the vessel It refers to the structure installed on the outer wall.

However, a large ship is a structure with a considerable height, and the height of a large cargo ship or passenger ship exceeds tens of meters. In addition, since the block structure constituting a large-sized ship has a considerable height, the stability of the patriarch (that is, scaffold) supporting the operator at a considerable height is required to perform various operations required for drying the ship.

In the conventional Korean Utility Model Publication No. 2011-0000903 (Jan. 27, 2011), in order to install a chief board for a welding work or a painting work at a high position in general, After the chief piece is welded and attached, a bracket is installed on the chief piece, and then a chief board is laid on the bracket.

Generally, the chiefs (footrests) are installed along the longitudinal direction of the work area, so that it is possible to provide a sufficient work space and a moving space for the workers, and to develop a new type of chiefs There is a need.

However, these patriarchs not only require a considerable amount of time and labor for installation and removal, but also have the disadvantage of requiring various facilities (for example, safety nets) for safety management of the patriarchs.

In addition, in order to install the chief board, the conventional chief footstep structure for shipbuilding as described above is required not only to weld the chief piece to the wall of the ship block but also to attach the chief piece after the chief structure is used It is necessary to remove the chief piece welded to the wall of the ship block, thereby excessively installing and demolishing the chief structure, and at the same time, it takes a long time to install and dismantle.

If the chock pieces welded to the ship block wall are removed, the coating surface of the ship block wall is damaged, so that the chock pieces need to be removed and then the ship block wall must be repainted, There is a problem that the drying time of the ship is delayed as well as the increase of the drying time of the ship.

In addition, since the footrest (footrest) is installed along the longitudinal direction of the work area, conventionally, when the footrest is connected to the footrest, one end of the footrest is obtained on another footrest, The movement is not easy and the joint between the foot plate and the foot plate is insecure, causing a psychological uneasiness of the worker.
