  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a louver fence, and the louver fence A is formed into a strip on a transparent substrate 31 by extruding two colors of transparent and translucent or opaque resin. By using a molding panel 3 in which many blindfolded portions 32 having a full length in the width direction are embedded and molded in parallel, the blindfolded portions 32 and the remaining transparent portions 33 are alternately arranged on the transparent substrate 31 in the vertical direction. The louver function is given by installing them adjacent to each other vertically in the aluminum frame 1 through the ventilation space 26. In this example, the molded panel 3 is made of acrylic and translucent resin. It is based on highly weather-resistant resins such as polycarbonate, polycarbonate, ASA, and AES.

  The molded panel 3 is, for example, about 8 to 15 cm long, about 10 cm in this example, and has a horizontal length of about 1 to 2 m, and 2 m in this example. At this time, the thickness is 1 to 5 mm, 2 mm in the present example, the thickness of the blindfold 32 is 3 mm or less, and 0.05 mm in the present example. .

  The molded panel 3 is formed by two-color extrusion molding of a transparent resin for the transparent substrate 31 and, for example, a translucent or opaque resin for the blindfold portion 32 in which a white pigment is added to the transparent resin. Molding is performed by joining molten resin supplied through different flow paths inside the mold, and in the same direction, the melted translucent or opaque resin is directed to the molten transparent resin, for example from one side to the other. And a large number of the translucent or opaque resins are embedded in the transparent resin substrate 31 in the longitudinal direction. At this time, the translucent resin in the molded panel 3 of the present example is such that one end of the translucent resin 32 is exposed on one side of the front and back sides from the front and back ends of the transparent substrate 31 to the other end or an intermediate position thereof. In this case, it is assumed that the embedding is performed so that the transparent resin is covered or the tip is exposed.

  In this example, the blindfolded portion 32 of the molded panel is embedded and inclined with respect to the transparent substrate 31, and at this time, the uppermost blindfolded portion 32 that is inclined and embedded is formed. The lower end and the upper end of the lower blindfold portion 32 are arranged horizontally or overlapped with each other to prevent see-through of the front and back surfaces due to the exposure of the transparent portion 33. Further, at this time, the tilted embedding of the blindfold portion 32 of the molded panel 3 is performed. The angle of the molding can be set to 70 degrees or less. In this example, the angle is set to 50 ± 5 degrees with respect to the transparent substrate plane.

  That is, in the two-color extrusion molding, the translucent or opaque resin is supplied in an oblique direction toward the crossing direction of extrusion with respect to the molten transparent resin, thereby embedding the translucent or opaque resin. The molding is in an inclined state. At this time, the supply in the oblique direction is 50 ± 5 degrees, preferably 50 ± 3 degrees in accordance with the sun angle of spring and autumn described later, which is about 50 degrees. It is supposed to be.

  In this way, the molded panel 3 in which the translucent resin is embedded is formed as a louver fence A by vertically installing it in the aluminum frame 1, that is, upright and vertically in series. In the example, the upper and lower arrangements of the molded panel 3 in the aluminum frame 1 are arranged such that the end of the panel is held by the installation frame 2 installed on the opposed vertical frame 11 in the aluminum frame 1. In addition, the installation frame 2 is provided with a wind plate 23 directed from one end to the other in the width direction, and the ventilation space 26 is provided in the wind plate 23. This is due to the opening communicating between the top and bottom.

  In this example, the aluminum frame 1 is composed of a vertical frame 11 and a horizontal frame 12 made of an extruded aluminum material having a relatively narrow depth width of, for example, about 2 cm so as to form the outer frame of the louver fence A. Similarly, a number of installation frames 2 having a depth smaller than that of the vertical frame 11, which are also made of aluminum extruded material, are fixed in the vertical direction, and the upper and lower ends of the molding panel 3 positioned at the uppermost and lowermost positions are respectively connected to the aluminum frame 1. The molded panel 3 is placed in series with the aluminum frame 1 by holding the upper and lower ends of the panel 3 in the vertical direction, and is installed on the aluminum frame 1. It is.

  The installation frame 2 is provided with a panel receiving groove 21 and a tapping hole 22 on one of the upper and lower sides, and a windshield plate 23 on the other side of the upper and lower side, and a pressing edge 25 for fixing the molded panel fitted in the panel receiving groove 21. At this time, the windbreak plate 23 is formed on one side in the width direction of the installation frame 2, that is, the panel receiving groove 21 or the tapping hole 22, for example, the panel receiving groove 21 in this example. It has a C-shaped or U-shaped cross section provided with a wind pressure attenuating groove 24 so that wind can be received from the end in the width direction toward the intermediate position in the width direction and the wind pressure can be attenuated. To the tip of the wind pressure attenuating groove 24 is about 2 cm. The horizontal frame 12 of the aluminum frame 1 that holds the uppermost and lowermost molded panels 3 is provided with a panel receiving groove 21, a tapping hole 22, and a pressing edge 25 in the same manner except for the windshield plate 23.

  The erection frame 2 is a common member that is used to hold the upper and lower ends of a molded panel 3 by inverting a single aluminum extruded material up and down in this example. By inserting both ends in the longitudinal direction between ribs at both ends in the width direction of the vertical frame and coming into contact with the opposing surface of the vertical frame 11, the screws 4 from the vertical frame 11 side are screwed into the tapping holes 22. An upper end or a lower end of the molded panel 3 is inserted into the panel receiving groove 21 and the panel receiving groove 21 is formed in the gap between the panel 11 and the molded panel 3. The formed panel 3 is held by fitting the pressing edges 25. At this time, the upper and lower ends of the uppermost and lowermost formed panels 3 with respect to the horizontal frame 12 are also provided in the panel receiving grooves as in the installation frame 2. 21 using the ledge 25 It is performed retention.

  The installation frame 2 is arranged so that the upper end and the lower end of the wind pressure attenuating groove 24 from one side in the width direction of the windshield plate 23 toward the middle position in the width direction are horizontal or slightly overlapped with respect to the vertical frame 11. In this way, an opening communicating with the upper and lower sides having a width of, for example, about 1 cm is disposed between the upper end and the lower end defining the wind pressure attenuation groove 24, and the ventilation is communicated by the opening communicating with the upper and lower sides. A space 26 is provided.

  The molded panel 3 is held in series in the vertical direction in a state of standing vertically at the intermediate position in the width direction of the vertical frame 11, particularly at the center position, thereby being inclined and embedded in the molded panel 3. The blindfolded portion 32 is maintained on the aluminum frame 1 while maintaining the tilted state, and the front and back sides are prevented from being seen due to the exposure of the transparent portion 33 arranged alternately with the blindfolded portion 32 in the vertical direction. is there. Further, by setting the inclination angle of the blindfold portion 32 to 50 ± 5 degrees, preferably 50 ± 3 degrees, the transparent portions 33 arranged alternately with the blindfold portions 32 are set to have the same inclination angle. By directing in the direction of the sun in the spring and autumn, sunlight passes through the transparent portion 33 regardless of the installation height of the louver fence A. Reachable. Therefore, the surface of the earth can enjoy the irradiation of sunlight that is substantially the same as the state in which the louver fence A is not installed, and can reduce the transmission of the sunlight by the blindfolded part 32 and limit the irradiation in summer. Can thus be made suitable for the growth of plants, for example.

  In this example, a series of arrangements of the molded panels 3 in the aluminum frame 1 are prepared in several types, for example, four, five, and seven, with various louver fence heights being changed. . That is, when the number of the molded panels 3 is four, the height of the louver fence A is about 50 cm, about five centimeters when the number is five, and about 80 centimeters when the number is seven. The louver fence A of this example can be formed as thin as about 2 cm of the depth width of the vertical frame 11, and thus exhibits the louver function. However, the louver fence A having a depth as thin as possible can be obtained.

In the figure, when the horizontal width of the molded panel 3 is long, 13 is arranged on the back surface of the molded panel 3,
An intermediate vertical frame used as necessary is shown so as to prevent the molded panel 3 from being rocked by wind pressure by being fixed by screws 4.

  Although the illustrated example is as described above, the molded panel has a blindfold portion and a transparent portion alternately arranged in the vertical direction vertical or the horizontal direction alternately, and the blindness is ensured by interrupting the transparent portion by the blindfold portion. Including this case, the angle of inclined embedding of the blindfolded portion of the molded panel is set to 0 to 70 degrees with respect to the transparent substrate plane, and the sectional shape of the blindfolded portion is, for example, a rhombus cross section or a circular shape. Appropriate shapes such as cross-sections, the transparent parts of the remaining shape are alternately arranged in the vertical direction, and when the blindfolded part is embedded and tilted in the transparent substrate, the transparent part remains thin on the front and back surfaces. In the same manner, it is possible to ensure the blindness by interrupting the transparent part, omit the installation frame, place the molded panel directly in the aluminum frame, and between the molded panels. In arranging the ventilation space, etc., in implementing the present invention, a louver fence, transparent and translucent resin, two-color extrusion molding, molded panel, transparent substrate, blindfolded part, transparent part, aluminum frame, ventilation Space, high weather resistance resin used as needed, angle of oblique embedding of blindfolded parts, each concrete shape such as construction frame, structure, material, application, composition, relationship between these, addition to these, etc. Various forms can be employed as long as the gist of the invention is not violated.
