うな特性を簡易に得しめる。(Prior art) Forming the roofing material of a permanent building with a membrane material inevitably makes it lightweight, which makes the structure of the building in general simpler and lighter, and greatly eliminates the need for supports in large buildings. It has the advantage of being appropriately translucent and allowing sunlight to enter during the day, and is gradually being adopted for tennis and other various competitions and sports facilities, gardening and exhibition halls, warehouses, and more. In other words, by increasing the internal air pressure of a building covered with resin membrane material to, for example, 0.1Kg/ cm2 ,
The membrane material floats and bulges in the direction of the top surface and hardly applies any load to the support structure material, so that the above-mentioned characteristics can be easily obtained.

発明である。"Effects of the Invention" Since the present invention as explained above uses a continuous porous polytetrafluoroethylene film, it has excellent weather resistance and corrosion resistance, and is particularly suitable for porous materials with a porosity of 75% or more. Because of this, it is extremely lightweight, and as mentioned above, under the conditions of increasing the atmospheric pressure inside a building, it is sufficient that the level of increase in pressure is considerably small, and it is finely porous with a pore diameter of 0.5 μm or less. As such, it is possible to ensure sufficient waterproofness, form a favorable roofing material expansion state under relatively light pressure conditions, and is flame retardant. Therefore, even if the continuous porous polytetrafluoroethylene film described above is made sufficiently thin, it has appropriate tensile strength and other strengths, and can withstand semi-permanent durability against stormy winds and other external conditions. This invention has the effect of making it possible to obtain the same at low cost, and is a highly effective invention industrially.
