BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment according to the present invention. In the figure, 1
Is a building such as a hangar of an airplane, 2 is an opening having a large opening forming a large entrance and exit of the building, 3 is a telescopic air beam provided at the opening and provided to open and close the opening. It is an air mat (however, in this embodiment, only an air beam is used, so it is simply referred to as an air beam hereinafter). Reference numeral 4 denotes an opening / closing control device 4 provided so as to expand and contract the air beam by supplying and discharging air to and from the air beam 3.

The opening 2 is formed by erecting an appropriate number of steel columns 13 on both sides, and forming a pair of steel beams 14 at the upper ends of the steel columns. A plurality of rail support members 15 are provided between the two steel beams. It is installed at equal intervals. A pit 16 is provided on the floor of the opening 2 along the opening, and a plurality of rail support arms 17 project from both side edges of the pit into the pit. And
A pair of guide rails 5 are arranged in parallel between the middle of both steel beams 14 and the middle of the pit 16 with the groove surfaces facing each other, and the lower surface of each rail support member 15 and the tip of each rail support arm 17 are provided. And let them support.

The air beam 3 is provided on each of the upper and lower guide rails 5.
, And a plurality of rod-shaped double membrane members 6 are formed in a line in series, and the left and right rod-shaped double membrane members 6 have an upper end and a lower end. A pair of left and right electric saddles 10 (FIG. 7) are mounted, and these electric saddles are movably engaged with a pair of upper and lower guide rails 5, respectively.
Further, a pair of left and right rollers (not shown) is provided at the upper end and the lower end of the plurality of intermediate rod-shaped double membrane members 6, respectively, and these rollers are movably engaged with the pair of upper and lower guide rails 5, respectively. . The provision of the electric saddle 10 in this way is
This is mainly for the purpose of enabling the air beam 3 to be opened and closed mainly by air to be opened and closed by electric power. Note that the double membrane member 6 may be plate-shaped. All the rollers may be replaced with the electric saddle 10. Other electric opening and closing means may be used in place of the electric saddle 10. Opening and closing when the wind load is small may be performed only by an electric opening / closing means such as an electric saddle without depending on supply / discharge of air. In this case, since the wind load is small, the function and shape of the shutter can be maintained without filling with air.

The opening / closing control device 4 is provided with a reversible blower 7 at an appropriate position in the pit 16, and the reversible blower is connected to each rod-shaped double membrane member 6.
The flexible hose 8 is connected via a flexible hose 8 to supply and discharge air to each rod-shaped double membrane member 6. In addition, a valve mechanism 9 that restricts outflow of unnecessary air from each rod-shaped double membrane member 6 is provided at an appropriate position in an air passage from the reversible blower 7 to each rod-shaped double membrane member 6. Further, a sensor 12 for detecting a wind load applied to the air beam 3 is provided at an appropriate position.
When the value detected by the sensor becomes equal to or more than a set value, the reversible blower 7 is operated to supply air excessively from the reversible blower, so that the pressure in the air beam 3 is increased. The rod-shaped double membrane members 6 may be communicated with each other to supply and discharge air to all the rod-shaped double membrane members 6 with one flexible hose 8.
The valve mechanism 9 may be an electromagnetic valve that can be electrically controlled.
As the sensor 12 for detecting the wind load, an anemometer, an anemometer, a strain gauge directly attached to the air beam 3, or the like is appropriate.

The open / close control device 4 includes an open / close switch, an air / electric changeover switch, a radio-controlled receiver, a microcomputer and a storage device for centralized control, a driver for a reversible blower, a driver for a valve mechanism, and an electric saddle. A control box 11 equipped with a screwdriver and the like is provided at an appropriate place in the building 1, and a radio control transmitter 20 is separately provided so that the reversible blower 7, the valve mechanism 9, and the electric saddle 10 are stored in a storage device. A program is controlled based on the data, and the control is also possible by an input signal from the sensor 12. This will be described in terms of function as follows.

In the control box 11, the air
The electric changeover switch is usually set to the air side. When the open / close switch is closed in the state where the air beam 3 is open, the reversible blower 7 rotates forward, and the valve mechanism 9 is opened. Air is supplied to the membrane member 6, and each bar-shaped double membrane member 6 expands, and the air beam 3 is guided and extended by the upper and lower guide rails 5 to close the opening 2. With this closing, the valve mechanism 9 is also closed to prevent unnecessary outflow of air from each rod-shaped double membrane member 6. In this closed state, when a wind load equal to or greater than the set value is applied to the air beam 3, the sensor 12 detects this and the reversible blower 7 further rotates forward, and the valve mechanism 9 is opened, and the reversible blower 7 Air is pressurized and supplied to each rod-shaped double membrane member 6, and the pressure inside each rod-shaped double membrane member 6 is increased, so that strength and rigidity are increased. Since the stress of the film material of the air beam 3 is increased only when necessary, its creep is minimized.
Next, when the open / close switch is opened while the air beam 3 is closed, the reversible blower 7 is rotated in the reverse direction, the valve mechanism 9 is opened, and the air in each rod-shaped double membrane member 6 becomes flexible. Discharged through the hose 8,
Each bar-shaped double membrane member 6 contracts, and the air beam 3 is guided by the upper and lower guide rails 5 and contracts to open the opening 2. With this opening, the valve mechanism 9 closes and the contracted state of the air beam 3 is maintained. By the way, when the air / electric changeover switch is switched to the electric side, the electric saddle 10 becomes active in place of the reversible blower 7, and when the open / close switch is operated to open or close in this state, the required electric saddle 10 Moves forward and backward along the upper and lower guide rails 5, and the valve mechanism 9
Is opened to allow air in each rod-shaped double membrane member 6 to freely enter and exit through the respective pipes 18 and the flexible hoses 8, so that the air beam 3 can be electrically opened and closed. The above operation can also be performed by the radio control transmitter 20, and the operation signal from the radio control transmitter 20 is received by the radio control receiver, whereby the various operations described above can be caused.

Note that, instead of the reversible blower 7, an air compressor dedicated to air supply and a vacuum pump dedicated to air discharge may be provided. The opening and closing of the air beam 3 may be detected by a limit switch or the like, and the expansion and contraction movement may be stopped.

[0018]

According to the present invention, a shutter having a large aperture can be remarkably reduced in weight and simplified by using an air beam / air mat 3 which can be expanded and contracted, and has rigidity and strength. The opening / closing trajectory can be kept small, the cost can be significantly reduced, and the cost for management and operation can also be reduced. Further, since air pressure is applied to the inside of the air beam / air mat 3 according to the wind load detected by the sensor, creep of the film of the air beam / air mat 3 can be minimized, and no trouble occurs.
