In addition, many of these types of cured morning glories are completely fixed, so they have to be dismantled each time they become a nuisance when unloading with a crane or the like.

Furthermore, hanging materials are usually installed between the tips of the cured morning glories and the temporary scaffolding. As a result, there was a risk that falling objects would bounce off the hanging materials, jump over the cured morning glories, and fall underground, causing an unexpected accident.

This invention was proposed in order to solve these problems, and allows the installation and dismantling of cured morning glories to be carried out extremely easily and safely on temporary scaffolding that allows for safe work, and also prevents falling objects. To provide a foldable type of cured morning glory that can completely prevent sudden accidents such as jumping over the cured morning glory and falling to the ground.
