BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a climbing type all-weather temporary roof capable of avoiding bad weather such as wind and rain or direct sunlight, mainly when constructing a middle-high-rise building.

[0002]

2. Description of the Related Art Generally, in the construction work of buildings such as RC structures and steel structures, it is inevitable to encounter bad weather such as wind and rain and intense heat because the construction work takes a long time. The work in such bad weather significantly lowers the workability, and sometimes the work cannot be performed at all, which may be a major cause of the construction stagnation. In addition, the construction accuracy of work such as welding, which is easily affected by the weather, is not only significantly reduced, but also dangerous.

For this reason, recently, a simple upper house such as a tent roof is erected overhead, or the floor of the rooftop floor is constructed first to make the upper house, but the former method is underground. It can only be used during the partial construction period, and cannot be handled until the construction on the ground floor. It may even be damaged by being blown by gusts of wind. On the other hand, the latter can be used only for the construction of a steel frame structure and cannot be used for other constructions such as RC structures, so that the range of use is naturally limited.

The present invention has been made in order to solve the above problems, and can be used as a house for all the steps of construction work, and the opening necessary for loading the construction work can be set at a free position. It is an object of the present invention to provide a climbing type all-weather roof for construction work that can be secured, is easy to assemble and dismantle, and has a function as an external scaffold.
