DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary roof made of a film-like material and a top sheet which are filled with air or helium gas so that the beam has rigidity, and is particularly excellent in handleability at a construction site. The present invention relates to a temporary roof that is stable for a long time and can be put to practical use, and a method for constructing the temporary roof.

2. Description of the Related Art A floating roof made of a film-like material configured to be filled with helium gas and floated is disclosed in, for example, Japanese Patent Application Laid-Open No. 4-33.
No. 9966. The technology disclosed herein is a temporary roof that is configured with a membrane material itself that fills a floating roof (temporary roof) with helium gas, and is configured to be able to float by filling the tube with helium gas. However, in the case of such a conventional floating roof, this type of floating roof is required for ordinary large-scale construction or various events in which a large span roof that requires this type of floating roof is required. It is difficult to do that. In addition, this floating roof is not realistic because it uses a large amount of extremely expensive helium gas and requires temporary curing costs.

[0003] In addition, the large area must be handled at the construction site, but filled with helium gas.
When the roof shape is reached, it becomes a lightweight floating roof, but before filling with helium gas, it is a heavy cloth sheet, and lifting equipment such as heavy equipment must be prepared, which is insufficient for handling at various sites. It is. In addition, since the roof or the helium gas is filled to maintain the shape of the roof by its internal pressure, it is difficult to maintain the shape of the roof if the filled air or the helium gas leaks in a large amount. Also, when opening and closing the roof, the entire roof must be slid sideways or temporarily removed. This method of opening and closing requires the use of mechanical means and is limited only when there is sufficient site space. At present, such as rain curing for the construction of detached houses, a number of square single sheets (blue sheets) are superimposed, and a temporary roof is used as a temporary roof. In addition, the temporary roof made of the blue sheet takes time and effort to pay before and after every work and is easily torn, and requires a lot of time and labor for handling on site. Therefore, in the current state of detached house construction, rain curing takes a lot of time and effort, but the curing material is easily broken, so there are many accidents due to rain leakage, and construction companies have difficulty in quality control and process control. You are in a situation. In addition, there is a situation in which a house under construction is getting wet with rain, which makes it difficult for the owner to deal with complaints.
