Specifically, as shown in FIGS. 5 (A) and 5 (B), the insect repellent net 17 provided on the entire surface of the exhaust port B extends beyond the air supply tube 6 toward the heat insulating air layer A. By sticking the insect net 17 to the air supply tube 6, the occurrence of surface tension can be suppressed and adhesion (adhesion) can be prevented.
The air supply tube 6 is made of a flexible synthetic resin or rubber sheet, and air supply holes 6a having a diameter of about 6 mm communicating with the heat insulating air layer A are spaced apart by about 30 mm in the vertical direction. Two are provided, and are provided with an interval of, for example, 500 mm in the longitudinal direction of the house. However, the air supply holes 6a ... are shaped and sized so that the air supply tube 6 expands to be in close contact with the air layer forming films 20 (21) and 30 inside and outside, and air can be blown into the air layer space A. There is no limitation to the dimensions and the number.

A small and lightweight electric fan 5 that blows air from the indoor side of the air house 1 toward the air supply tube 6 directly to the arrangement that sandwiches the air layer forming film 20 (21) on the inner side and the air supply tube 5 directly. The air blower outlet of the electric fan 5 is directly opened toward the air supply tube 6.
FIG. 7 shows a configuration in which the electric fan 5 is attached to the inner air layer forming film 20 and the air supply tube 6. A small electric fan 5 is applied to the inner surface of the air layer forming film 20 on the inner side, and the film 20 and the air supply tube 6 are sandwiched by a pressing edge 50 applied to the inner surface of the air supply tube 6. And is attached by bolting. Incidentally, the location where the electric fan 5 is attached is opened to a size and shape that allow air to enter and exit.
The electric fan 5 has an output of about 25 W as an example, and is installed in the longitudinal direction (about 30 m) of the air supply tube 6 to form the air house outer body 10 by operating for about 10 minutes. Can do. However, the electric fan 5, and a plurality placed in the longitudinal direction of the air supply tube 6 (about 30 m), the configuration of forming the air house outer body 10 blowing air to a more quick and air layer space A It can also be implemented.
Although illustration is omitted, the left and right air supply tubes 6 and 6 are connected to each other by a communication tube, and the small electric fan 5 is installed only on one of the air supply tubes 6, Or it can supply in common with the one electric fan 5 by installing in the said communicating pipe.

Next, a procedure for forming the air house outer body 10 having the heat insulating air layer A by blowing air into the air layer space A by the electric fan 5 will be described.
First, in the procedure for supplying air to the air space A, A, air is supplied by switching on the electric fans 5 installed on the air layer forming films 20 and 21 on the left and right inner sides, as shown in FIG. In this way, the left and right air layer spaces A and A are expanded. Air is blown into the air supply tube 6 from the electric fan 5 and the left and right air supply tubes 6 and 6 are deflated as shown in FIG. The exhaust port B is closed as shown in FIG. Subsequently, the air escapes from the air supply hole 6a of the air supply tube 6 and is sequentially and efficiently blown into the air layer space A.
Thus, the expanded left and right air supply tubes 6 are in close contact with the inner and outer air layer forming films 20 (21) and 30 and close the gaps between the inner and outer air layer forming films 20 (21) and 30. Therefore, air does not leak to the outside of the air layer forming films 20 (21) and 30 inside and outside, and the air house outer body 10 having the heat insulating air layer A can be formed.

  As shown in FIG. 4, the air blown excessively into the heat insulating air layer A by the electric fan 5 pushes away the outer air layer forming film 30 in accordance with the increase in internal pressure, so that there is a gap with the air supply tube 6. It is discharged from the exhaust port B. In other words, as long as the electric fan 5 blows air into the heat insulating air layer A (the electric fan is rotated and released), the heat insulating air layer A having a certain layer thickness is formed, and excess air exceeding the certain layer thickness is exhausted by itself. By forming and overflowing, the air pressure can be self-maintained below a certain value, and an excellent heat insulation effect can be expected. Therefore, there are no accidents in which the air layer forming films 20 (21) and 30 inside and outside expand due to excessive air pressure and expand excessively or are damaged in an extreme case.

  In addition, when air is blown into the heat insulating air layer A, for example, an operator operates the electric fan 5 intermittently according to the swelling thickness of the heat insulating air layer A to blow air into the heat insulating air layer A. It can also be implemented. Alternatively, an electric switch mechanism comprising an electric switch mechanism as a detecting means for automatically adjusting the bulge thickness of the heat insulating air layer A to a set value and an electric switch mechanism operated by using the electric switch mechanism is installed. The air switch can also be implemented while adjusting the bulge thickness by the electric switch mechanism.

  Incidentally, as an exhausting procedure for extracting air from the adiabatic air layer A, the electric fan 5 is stopped by turning off the switch, and the air supply tube 6 is deflated. Then, the close contact between the air supply tube 6 and the inner and outer air layer forming films 20 (21) and 30 is released and the exhaust port B is opened widely, so that a large amount of air can be discharged from the exhaust port B at a stretch. It is.

Note that the snow in strong winds and winter films of roof of the air house 1 is centrally or locally compressing the air layer formation film 20 (21), when there is a risk that 30 sags are shown in FIG. 8 As described above, one end of the sealing sheets 8 and 8 suspended from the exhaust port B is attached to the left and right sheet fastening devices 41 and 43 that fasten the fixed ends 20b and 21b of the inner air layer forming films 20 and 21. The other end is attached along the longitudinal direction of the exhaust port B, and the other end is sealed with a sealing means 80 such as a double-sided tape, chuck or fastener, and both ends of the sealing sheets 8 and 8 are sealed. The air is continuously supplied by the electric fan 5 in a state where the air is sealed, and the internal pressure of the heat insulating air layer A is increased. Then, the air house outer body 10 is in a state of being tightly stretched, and the snow on the roof portion of the air house 1 can be shaken off toward the ground, and can be formed with a strength that can withstand strong winds. In addition, the said sealing sheets 8 and 8 can also be implemented as a structure which welds one end to the said left and right air supply tubes 6 and 6, and hangs down from the exhaust port B. As shown in FIG.

FIG. 9 shows a configuration in which a vinyl chloride pipe 7 (hereinafter referred to as a polyvinyl chloride pipe) is installed as a pipe material in place of the air supply tube 6.
Specifically, the inner and outer air layer forming films without blocking the exhaust port B at the position of the fixed end adjacent to the exhaust port B of the inner air layer forming films 20 and 21 or the position on the near side thereof. A PVC pipe 7 having a diameter that closes the gap between 20 (21) and 30 is installed over the entire length along the longitudinal direction of the exhaust port B. The PVC pipe 7 is provided with air supply holes 70 communicating with the heat insulating air layer A on the side facing the heat insulating air layer A, and an electric fan 5 that blows air toward the PVC pipe 7 forms an inner air layer. The films 20 and 21 and the polyvinyl chloride tube 7 are placed between them. That is, air is supplied by the electric fan 5 and air is blown from the PVC pipe 7 into the left and right air space A to form the air house outer body 10 having the heat insulating air layer A.

Next, the procedure for supplying and exhausting air to the air space A will be described based on the curtain system 15 formed on the roof portion of the house shown in FIG.
First, in the procedure for supplying air to the air space A, the inner and outer air layer forming films 20 (21) and 30 are unwound by rewinding the winding shaft 90 (91) by rotating the handle of the rotation transmission device. When deploying (midway) or when deployed (after deployment), the electric fan 5 is switched on to supply air and expand the air layer space A. The electric fan 5 is blown into the air supply tube 6, and first, the air supply tube 6 is inflated to close the exhaust port B. Subsequently, the air escapes from the air supply hole 6a of the air supply tube 6 and is sequentially and efficiently blown into the air layer space A. Thus, the expanded air supply tube 6 is in close contact with the inner and outer air layer forming films 20 (21) and 30 and closes the gap between the inner and outer air layer forming films 20 (21) and 30. Therefore, air does not leak to the outside of the air layer space A, and the air layer forming films 20 (21) and 30 can form the heat insulating air layer A.
The air blown excessively into the heat insulating air layer A pushes out the outer air layer forming film 30 in accordance with the increase in internal pressure, escapes from the gap with the air supply tube 6 and is discharged from the exhaust port B. . In other words, as long as the electric fan 5 blows air into the heat insulating air layer A (the electric fan is rotated and released), the heat insulating air layer A having a certain layer thickness is formed, and excess air exceeding the certain layer thickness is exhausted by itself. By forming and overflowing, the air pressure can be self-maintained below a certain value, and an excellent heat insulation effect can be expected.

Next, a procedure for exhausting air to the adiabatic air layer A will be described. First, the electric fan 5 is stopped by turning off the switch, and the air supply tube 6 is deflated. Then, the close state between the air supply tube 6 and the inner and outer films 20 (21) and 30 is released and the exhaust port B is opened, so that a large amount of air can be discharged from the exhaust port B at a stretch. Therefore, the rotation transmission device of the rotate handle winding shaft 90 (91) in and out of the air layer forming the film 20 (21), said inner and outer air layer formed by the winding shaft 90 (91) when winding the 30 films 20 (21), the air in the heat insulating air layer A can be exhausted at a stretch at a speed that is not inferior to the winding speed of 30 (the squeezing effect of the air layer forming film 2). When winding 31, there is no inconvenience that the winding shaft 90 (91) is lifted by air pressure, and the workability is excellent.
Even when the electric fan 5 is turned off (when the power of the electric fan 5 is forgotten to be turned off) and the air supply tube 6 is inflated, the air layer forming film 20 inside and outside is wound around the winding shaft 90 (91). (21) By rolling up 30, the outer air layer forming film 30 is pushed away by the air pressure, and air is let out from the gap between the outer air layer forming film 30 and the air supply tube 6, and the exhaust port Since it can be discharged from the portion B, there is no inconvenience that the winding shaft 90 (91) is lifted by the air pressure, and the winding operation of the inner and outer air layer forming films 20 (21) and 30 can be performed smoothly. Further, there is no accident that the air layer forming films 20 (21) and 30 inside and outside expand and are excessively stretched or damaged.

  Although the present invention has been described based on the illustrated embodiment, the present invention is not limited to the configuration of the embodiment. I would like to remind you that it includes the scope of design changes and other applications and modifications that will be performed by those skilled in the art as needed.
