2. Description of the Related Art Conventionally, in construction work, it is common to suspend work because of poor workability during rainfall and snowfall, and accidents are prone to occur, but bad weather continues during the rainy season and winter in northern countries. Of these days, there were no days available for work, which meant that the construction period was significantly delayed and profitability deteriorated. Therefore, we sometimes cover the roof so that we can work even if it rains a little, but since this roof is mostly closed and built-in, it becomes an obstacle on a sunny day, and it is an obstacle to the lower building. There was a problem that it was not useful for the high-rise building construction, which had to be moved to the upper layers one after another, because it was not convenient.
