Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar radiation control device for a roof capable of controlling and shielding the amount of sunlight entering from a translucent roof member.

[Conventional technology]

2. Description of the Related Art Conventionally, as a method of adjusting or blocking incident light, a so-called louver rotation method is often used, for example, even when provided directly under a transparent roof material. This is the eighth
As shown in the figure, a rotating shaft 22 is provided at the center of both ends of a large number of elongated blades 21, and a large number of blades 21 are simultaneously rotated in one direction by operating an interlocking rod 23, or the width of the blade 21. In some cases, interlocking cables 24 and 25 are provided on both sides in the direction, and the blades 21 are opened and closed by operating them in directions opposite to each other. Various mechanical parts such as gears, pulleys, and chains are often used for these operations. f indicates incident light.

[Problems to be solved by the invention]

However, in the louver system as described above, a mechanical joint and a drive device for simultaneously rotating a large number of elongated blade-like members constituting the louver are required, and even a small-scale one is liable to cause a failure. In particular, there is a problem that it is almost difficult to manufacture a large-scale one. Furthermore, it is extremely difficult to manufacture a transparent roof member along a deformed roof member or the like in which not only a uniform flat surface but also an inclined surface and a horizontal surface are mixed, and heat insulation is not good, There were various problems.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the related art, and has as its object to solve the above-described problems by providing a device for expanding and contracting a flexible bag-shaped sheet member.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a bag-shaped member that can be expanded or contracted into a tube or a plate by injecting or discharging gas, using a sheet material having a light reflecting function and a sheet material transmitting light, respectively. The bag-shaped members are formed separately and arranged alternately and in parallel at predetermined intervals on the lower surface of the roof member made of a translucent member, and the interval is set to be equal to or less than the diameter of the tubular shape of the bag-shaped member when it is enlarged. It is a solar radiation control device for the roof.

It is preferable that each bag-like member is configured to be able to exchange or circulate the gas inside via a pipe having an air volume control valve.

[Action]

Since the present invention is configured as described above, when gas is discharged from the bag-shaped member, the bag-shaped member shrinks and assumes a plate shape, and hangs down from the roof member. Therefore,
The sunlight passing through the transparent roof member can freely pass between the two types of bag-shaped members hanging at a predetermined interval. In this case, the solar light is not blocked when entering in the vertical direction, but is blocked by the bag-shaped member having a reflecting function when entering in an oblique direction. However, since the surface of the bag-shaped member has a reflection function, the surface of the bag-shaped member is reflected at a reflection angle corresponding to the incident angle to illuminate the lower side. In the case of a bag-shaped member made of a sheet that transmits light, the light is transmitted as it is and the lower part is irradiated. In this case, between the top and bottom of the roof, there is no heat insulating function other than the roof member.

Next, when gas is supplied to the bag-like member, the bag-like member expands according to the supply amount, and the space between the bag-like members becomes narrow, and sunlight is blocked by the bag-like member having a reflecting function. The amount of solar radiation to be reduced.

In addition, since the bag-shaped members that transmit light are provided between the bag-shaped members that reflect light, when both bag-shaped members are inflated to the same extent, the cross-section of both bag-shaped members is It has an oval shape and is pressed against each other, one of the bag-like members guides and introduces sunlight, and the thermal insulation effect is maintained by pressure. Further, if only the transparent bag-shaped member is inflated, the brightness in the room is doubled. In addition, if the amount of gas injected into both types of bag-like members is adjusted, the amount of solar radiation into the room can be arbitrarily adjusted.

Furthermore, by exchanging or circulating the gas inside the bag-shaped member through a pipe having a flow rate control valve, and by connecting an air conditioner in the middle of the pipe, a further improved heat insulating effect and indoor air conditioning, etc. Alternatively, it can be performed selectively.

As described above, the amount of solar radiation from the roof can be arbitrarily adjusted by covering the amount of gas supplied and the type of bag-shaped member to which the gas is supplied. Is unlikely to occur.

〔Example〕

Hereinafter, the present invention will be described with reference to the drawings. First to seventh
FIG. 1 shows an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a roof member,
It is composed of a thin transparent body fixed and indicated on the top, and its material is a glass plate, a polycarbonate plate, a weather-resistant transparent resin film or sheet, or the like, depending on the installation location.

Reference numeral 3 denotes a bag-like member having a light-reflecting function, which is made of a flexible film or sheet-like member, and is formed by laminating a thin film that reflects light, such as aluminum foil, on the surface to form a bag. In this embodiment, a resin film laminated with an aluminum foil is used.

Reference numeral 7 denotes a bag-like member having a light transmitting function, which is a bag made of a flexible transparent film or sheet-like member. These two kinds of bag-like members 3, 7 are arranged alternately and in parallel on the frame 2 of the roof, and the mounting interval d is the cross-sectional circle when the bag-like members 3, 7 are fully inflated. Radius or slightly smaller distance.

Reference numeral 4 denotes gas inlets and outlets provided in the bag-shaped members 3 and 7, each of which is provided with an air volume control valve 9 and these are communicated with an air duct 5, and the air duct 5 is connected to a blower 6 which can rotate in the reverse direction. Is done. The degree of expansion of each of the bag-shaped members 3, 7 is changed by adjusting the opening of the valve.

In addition, if relatively light weights as shown by symbols 3a and 7a in FIG. 2 are attached to the bag-like members 3, 7, the weight 3a is only released by the air volume control valve 9 to open the internal air to the outside air. The bag-shaped members 3, 7 shrink in a plate-like shape due to the weight of the bag, 7a.

Further, as shown in FIG. 3, the hanging members of the bag-shaped members 3, 7 are mounted on a circular pipe 17 rotatably supported by the frame 2, and the circular pipe 17 is rotated to be wound and stored. It is also possible to make the space less noticeable. It is also possible to connect the circular pipe 17 to the air duct 5 and supply and discharge gas through the air duct 5.

FIG. 4 shows the case where each of the bag-shaped members 3, 7 is inflated to the same size. Even in the daytime, when the sunlight is not directly above, the contact surface of the bag-shaped members is mirror-shaped. The sunlight is introduced into the room as reflected light S in addition to the direct light M, and the contacting bag-shaped members 3, 7 form a fixed air layer to maintain the heat insulating effect both day and night.

FIG. 5 shows a state in which only the bag-like member 7 having the function of transmitting light is sufficiently inflated, and the deflated bag-like member 3 having the reflection function is provided.
In this case, the direct light M or the reflected light S transmitted through the bag-shaped member 7 is much brighter than the case of FIG. 4 and the heat insulating effect of FIG. It will be kept the same as in the case. In order to block the solar radiation, only the other bag-shaped member 3 needs to be inflated, contrary to the above.

FIG. 6 shows an example in which a blower 6B for the bag-shaped member 3 and a blower 6A for the bag-shaped member 7 are separately provided. In this case, the rotation, stop, and rotation control of each blower are performed to form each bag. Make the expansion of the member variable, or each bag-shaped member of each duct 5A, 5B
The air flow control valves 9A, 9B may be provided in the branch pipes 8A, 8B connecting the switches 7 and 3, and may be variable. In this case, an air outlet 10 is provided on the side opposite to the air supply side (branch pipes 8A and 8B), and the blower 6
If the bag-like member is in an inflated state by continuously operating the air-conditioning device and air is constantly flowed inside, the air-cooling effect as well as the heat-insulating effect can be maintained. 10a is a flow control valve for controlling the amount of exhaust air. The branch pipes 8A and 8B in FIG. 6 correspond to the entrance 4 in FIG.

Next, FIG. 7 shows an embodiment in which the gas in the bag-shaped members 3, 7 can be circulated, and an air conditioner 14 is connected to the ducts 4A, 4B, and either or both of the bag-shaped members 3, 7 are provided. This is a diagram showing a case where conditioned air is supplied to the apparatus. In the figure, 11 is the entrance side, 12
Is an air flow control valve on the outlet side, and 13 is a return air pipe connected to return the air on the outlet side to the air conditioner 14 again. Reference numeral 15 denotes an outside air inlet to the air conditioner 14, which is used when the outside air is supplied to each bag-like member by a built-in blower without performing heating or cooling air conditioning.

Even when the gas pipeline shown in FIGS. 6 and 7 is adopted, the roof member 1, the frame 2, and the bag-shaped members 3 and 7 are not shown in FIGS.
Needless to say, this is the same as the case described with reference to the drawings.

〔The invention's effect〕

As described above, according to the present invention, since the use of the bag-shaped member is relatively light, it can be easily carried out even in a place having a large area, which has been difficult in the past, and can be applied to an atrium or the like of a glass roof. In addition to being suitable, it is extremely easy to adjust the amount of solar radiation and hardly causes a failure because almost no mechanical parts are used in the operation part for the adjustment,
Furthermore, it can follow curved or deformed roofs and walls, and is relatively inexpensive. In addition, since an air layer is formed by the expansion of the transparent bag-like material, the state of heat insulation can be improved.
By adjusting the inflated state of the bag-shaped members, it is possible to form a heat insulating layer as well as to control the amount of transmitted light, and to further improve the heat removal effect by ventilating the air inside the bag-shaped members. In addition, since the gas in the bag-shaped member can be circulated, there is also an effect that an air conditioner can be connected to enhance the indoor air conditioning effect.
