Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention is used for a building, for example, as a skylight, so that it is in a light-shielded state in summer due to the incident angle of sunlight and is in a daylighting state in winter. The present invention relates to a transparent plate material for use.

<Conventional technology> Conventionally, a skylight of a building is provided for the purpose of ventilation and lighting of a room, and a transparent glass plate using an openable window frame is usually used.

The above-mentioned skylight allows sunlight to enter the room and brighten the room, raising the indoor temperature.However, especially in the summertime, the temperature of the room is increased to increase the load on cooling equipment, for example, when returning home from going out In some cases, the interior of a room may become extremely hot due to the heating effect of sunlight.

Therefore, in order to block the above-mentioned summer sunlight from entering the room, a light-shielding material that can be opened and closed is installed outside or inside the skylight, and the light-shielding material is closed to control the incidence of sunlight in the room. The method was taken.

<Problem to be Solved by the Invention> However, since the above-mentioned light-blocking material that can be opened and closed is provided at a high position in a building, opening and closing operations are extremely troublesome.

Further, if the light-shielding member can be opened and closed by a simple operation by connecting an appropriate electric device, the facility cost becomes extremely high.

Further, when the light shielding material is in a closed state, there is a problem that the sunlight function of supplying the room with brightness by sunlight is also suppressed.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and has a horizontal stripe-shaped first pattern in which a first light-shielding layer and a first transmission portion are continuous on the outdoor side of a transparent plate. A second pattern of horizontal stripes parallel to the above-mentioned first pattern is formed by connecting the second light-shielding layer and the second transmission portion on the indoor side of the transparent plate, and the thickness of the transparent plate is T, 1 The width of the light-shielding layer is L1, the slit width of the first transmission part is S1, the width of the second light-shielding layer is L2, the width of the second transmission part is S2, and the incident angle of sunlight at the summer solstice is α, Assuming that the incident angle of the sunlight at the time of autumn is β and the incident angle of the sunlight at the winter solstice is γ, the second light-shielding layer is shifted laterally from the side edge of the first light-shielding by the length of (Ttanα). The width L2 of the second light shielding layer is set to (S1
+ Ttanβ-Ttanα), and the width of the second transmission part
By setting S2 to (Ttanγ-Ttanβ), the incidence of sunlight is controlled by the above-mentioned first and second patterns, the room is kept in a light-shielded state during the summer season from the equinox to the autumn equinox, and the The present invention relates to a transparent plate for a building which is in a lighting state in winter.

<Function> According to the present invention, the incidence of sunlight is blocked in summer and light is collected in winter, so that in summer, heating and supply to the room is suppressed,
Gentle heating can be provided in winter.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a transparent plate 1 for a building according to the present invention forms a horizontal stripe-shaped first pattern 3 on the outdoor side of a transparent plate 2 and a horizontal stripe parallel to the first pattern 3 on the indoor side. The second pattern 4 is formed.

The transparent plate member 2 is made of glass, a transparent acrylic resin plate, or the like, and has a plurality of strip-shaped first light-shielding layers 5 formed on the outdoor side. The first pattern 3 on the outdoor side is obtained by using the portion 6.
Is configured.

Similarly, a plurality of strip-shaped second light-shielding layers 7 are formed on the indoor side of the transparent plate 2 in parallel with the first light-shielding layer 5, and the surface of the plate 2 on which the second light-shielding layer 7 is not formed is formed. Second
The second pattern on the indoor side is obtained by using the transmitting portion 8.

The first light-shielding layer 5 and the second light-shielding layer 7 may be of any material and forming method as long as they have a property of blocking the transmission of sunlight. It may be configured by printing or by bonding a strip-shaped light-shielding tape or a thin plate material to both surfaces of the plate material 2.

Next, the light-shielding function and the daylighting function of the building transparent plate 1 of the present invention will be described.

As shown in FIG. 2, the thickness of the transparent plate 2 is T, the width of the first light shielding layer 5 is L1, and the slit width of the first transmission section 6 is S1.

At the time of the summer solstice in Japan, the altitude of the sun is the highest, and the sunlight indicated by R1 is incident on the perpendicular R of the plate 2 at an incident angle α. Therefore, the second light shielding layer 7 is
While being shifted laterally by Ttan α from the side edge of the light shielding layer 5,
When the first transmitting portion 6 is formed to be longer than the slit width S1, the sunlight R1 at the summer solstice can be shielded.

At the time of spring / autumn equinox, the sunlight indicated by R2 is incident on the perpendicular of the plate 2 at an incident angle β.

Therefore, the width L2 of the second light shielding layer 7 is set to (S1 + Ttan β−T
If it is formed longer than tan α), it is possible to shield the sun rays R2 at the time of the spring equinox and the autumn equinox, and at least to shield the sun rays during the period from the spring equinox to the summer solstice and the summer solstice to the autumn equinox.

In the embodiment shown in FIG. 2, since the width L2 of the second light-shielding layer 7 is set to L2 = S1 + Ttanβ-Ttanα, it is possible to shield the sunlight from the spring equinox to the autumn equinox.

At the time of the winter solstice, a solar ray indicated by R3 is incident at an incident angle γ. Therefore, the width S2 of the second transmission part 8 is (Ttan
γ-Ttan β), the sunlight R3 at the time of the winter solstice can be collected, and the sunlight from the autumn solstice to the winter solstice and the winter solstice to the spring equinox can be collected.

In the above description, the solar rays at the summer solstice, spring equinox / autumn solstice, and winter solstice are indicated by R1, R2, and R3, respectively. At dawn and dusk, the angle of incidence of each sun ray will be different. However, in the northern hemisphere such as Japan, the sun apparently rotates in a southward arc in the sky, so that the light-shielding layers 5, 7 and the transmissive portions 6, 8 are oriented in the east-west direction. This makes it possible to maintain the incident state of sunlight shown in FIG. 2 at dawn and dusk other than mid-south.

Therefore, the transparent plate 1 for a building according to the present invention has a width L1 of the first light-shielding layer 5, a slit width S1 of the first light-transmitting portion 6, a width L2 of the second light-shielding layer 7, and a slit width S2 of the second light-transmitting portion 8. In addition, by appropriately setting the installation direction and the installation angle of the building transparent plate material 1, the seasonal light-shielding state and daylighting state, and the light-shielding state and daylighting state at the time of irradiating sunlight are selected and executed as desired. be able to.

In addition, the transparent board 1 for buildings of the present invention can be used for the intended purpose by appropriately setting the patterns on both sides even in places with different latitudes such as Hokkaido and Okinawa, or even in the southern hemisphere. .

In the transparent plate 1 for buildings according to the present invention, any additional configuration may be added. For example, by using the transparent plate 2 having an ultraviolet absorbing function, 10%
Removes ultraviolet rays of 400mμ or less contained, and 45% contained 40
When the visible light of 0 to 770 mμ and the infrared light of 770 mμ or more, which is included in 45%, are collected, the light shielding state and the light collection state in the present invention become more practical.

<Effects of the Invention> As described above, according to the present invention, it is used for, for example, a skylight of a building, and the incidence of sunlight is reliably blocked in the summer from the spring equinox to the autumn equinox, and it is surely blocked in the winter from the autumn equinox to the vernal equinox. Can be lit.

Therefore, in summer, the temperature rise in the room and the incidence of ultraviolet rays are surely suppressed, so that the load on the cooling device can be reduced. At the same time, the room can be kept warm and illuminated in winter. In addition, each light-shielding layer does not allow the interior of the room to be seen from the outside, and the illumination light on the inside does not leak to the outside. Therefore, the light-emitting device can be effectively used particularly as a building for general home use.

In addition, the transparent plate for buildings of the present invention has a simple configuration in which a light-shielding layer having a horizontal stripe pattern is provided on both surfaces of the transparent plate, so that it can be easily and inexpensively manufactured. Since there is no need for equipment such as a light-blocking material, and labor and equipment for opening and closing it, the economical and practical effects are extremely high.
