Description

[Detailed Description of the Invention] (Field of Application of the Invention) The present invention relates to a variable air membrane structure building that can be used as a variety of sports venues, gathering halls, exhibition halls, and other various indoor facilities. be.

(Prior Art) Conventionally, air membrane structure buildings have been constructed using the so-called single membrane system as shown in Figs. 5 to 7, and as shown in Figs. 8 and 9.
A so-called beam method as shown in the figure has been proposed.

The former creates a sealed space with an integrally formed single air membrane Of, and supplies air pressure inside to levitate and support the air membrane 01 to form a dome, and the large volume of air pressure itself supplied inside. It has a structure that supports loads, has a small internal pressure level, and is easy to create an air membrane, and has good waterproof and heat retention properties, but it must be highly sealed, and if the air lock 02 is incomplete, the membrane will fall. As a result, there was a problem that ventilation was poor and the interior was likely to become hot and humid.

On the other hand, the latter creates an air film by connecting independently molded tubes 03, and supplies relatively high pressure air into the tubes 03 to float and support the air film to form a dome.
The structure supports the load using the bending resistance of the tube 03 to which high-pressure air is supplied, and since both ends are open, entry and exit is easy and ventilation is good, but the internal pressure level is high and the air film is difficult to mold in one piece. There were problems with membrane strength, waterproofness, etc.

As described above, the single film method and the beam method that have been proposed so far each have advantages and disadvantages, and are not satisfactory.

(Purpose of the Invention) The present invention was proposed in view of the above-mentioned conventional situation, and has a safe and economical air membrane structure that can create a comfortable indoor environment, without fear of membrane descent, etc. The purpose is to provide buildings.

(Structure of the Invention) The present invention is configured to take advantage of the features of the heavy membrane method and the beam method, and is designed to be integrated into both ends of a beam-type air membrane of a continuously formed tube structure that is suspended and supported by air pressure. Because the opening has a single layer air membrane that can be opened and closed,
If necessary, the openings at both ends can be opened with a single air membrane at both ends to use it as a beam system, or the openings can be sealed and used as a single membrane system.

(Effects of the Invention) Since the present invention is configured as described above, a beam method can be used when the load to be supported is small, and a single membrane method can be used when the load is heavy.

In addition, beans can be used with good ventilation, and conversely in winter, they can be used with good heat retention by eliminating ventilation, and they can also be used in a comfortable indoor environment regardless of the weather, such as wind, rain, wind, snow, or sunlight. can be produced.

Moreover, even when used as a heavy membrane method, it is safe because there is no need to increase the degree of sealing to prevent the membrane from falling.
Moreover, it is possible to increase the degree of freedom in the movement of people and objects in and out.

Furthermore, it is possible to have the effects that continuous shooting, relocation, construction, collection, foundation work, etc., which are the original characteristics of air membrane structure buildings, are easy and simple.

(Example) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

Figures 1 to 4 show one embodiment. 1 is a beam-type air membrane that is floated and supported by air pressure supplied inside, and is continuously formed using a polyester base fabric coated with vinyl chloride. It has a tube structure and can be used as a beam-type air membrane structure building by itself.

2 is beam type air l! ,! It is a single air membrane provided integrally at both ends of the beam type air membrane 1, and is composed of a net 3 and a transparent film 4 provided inside it, and can open and close the openings 5 at both ends of the beam type air membrane 1. It has a roll-up type structure that is rolled up upward when opening the opening 5.

Furthermore, by closing the opening 5 with the double-layered air membrane 2 and supplying air pressure to the internal space, it can be used as a single-layer air membrane structure building.

Note that air pressure is supplied to the beam type air membrane 1 or the single air membrane 2 by a known method using a blower or the like. The air pressure supplied is higher than the air pressure supplied into the heavy cloth membrane 2, and it is not necessary that all the tubes have the same pressure; high air pressure may be supplied at appropriate intervals. .

Furthermore, the supplied air may be warm air during snowfall in winter, and may be used for melting snow.

By having the configuration as shown in L, the first
It is possible to use it as a beam method as shown in the figure, or as a single film method as shown in FIG.

In other words, when used as a beam type, air pressure is supplied to the beam type air membrane 1 to float and support it, and the - type chamber air membrane 2 is
It is sufficient to open the openings 5 at both ends by winding up the material, and it is possible to improve ventilation during the hot summer months and the like, and to prevent wind, rain, and sunlight.

On the other hand, when the load to be supported becomes large due to heavy rain, wind and snow, etc., or when you want to use it with good heat retention, lower the - type chamber air membrane 2, seal the openings 5 at both ends, and apply air pressure inside. Because it can be supplied and used as a heavy H method,
It is resistant to heavy rain, wind and snow, and can create a comfortable indoor environment regardless of the weather conditions.

In addition, when used as a layered membrane method, even if the air rotor is incomplete, it is configured to be used in conjunction with the beam method, so there is no risk of the membrane falling, making it safe and allowing people and objects to enter and exit. can be carried out freely.

Moreover, it has all the characteristics inherent in air membrane structure buildings, and can produce many effects.

In addition, although the above embodiment shows an example in which the air membrane is made of polyester base fabric coated with vinyl chloride, the present invention is not limited to this, and other suitable materials may be used without departing from the gist of the present invention. It goes without saying that various modifications and changes can be made therein.
