Description

Scaffolding for Work {Scaffold}

The present invention relates to a scaffold for work, which is a temporary scaffolding structure mounted on a working wall when a ship is built or a structure is installed.

In general, scaffold is a temporary scaffolding structure that lifts various materials needed at construction and shipbuilding sites or allows workers to work in high places.

In particular, the ship's construction process builds the hull into a number of large blocks and combines them. Therefore, scaffolding is installed on the hull wall surface to perform various operations in the outer wall of the block of steel structures such as ships.

Since the scaffold is a place where the worker works directly, it should be installed safely on the hull. As it is a temporary structure, it should be able to minimize the labor and overall expenses incurred when installing or dismantling.

Typical scaffolding has a method of welding the chieftains pieces to the hull, bolting the brackets to each of the chieftains pieces, and then connecting the workbench to the brackets to install them.

However, the conventional scaffolds are large in size, so that after the installation of the hull dry, the hull drying is not visually beautiful to complete and leave the hull dry, so the dismantling demand occurs. The bolting process is very cumbersome, and the overall installation and dismantling of scaffolding requires a lot of labor, time and money.
