[0008] Before describing the embodiments, the correspondence between the claims and the drawings will be explained. However, any correspondence is not intended to limit the interpretation of the claims to the embodiments shown in the drawings, but is merely shown as a representative example included in the claims to aid understanding.

[0009] The louver material type A (4A) to the louver material type C (4C) are types included in the first embodiment. The louver material type D (8D) is a type included in the second embodiment. The louver material type E (8E) is a type included in the third embodiment.

[0010] The invention according to claim 1 is characterized in that the horizontal piece portion (upper horizontal piece portion 421 or lower horizontal piece portion 43) common to the louver panel body 2 equipped with louver material type A (4A) to louver material type E (8E) limits the width of the lower gap 221 formed between the upper louver material 4 and the lower louver material 4 in side view. This invention also includes Examples 1 to 3. The invention according to claim 2 is an embodiment in which a ventilation / screening section 22 using louver material type A (4A) is used, and corresponds to Fig. 10(A). This is an example included in embodiment 1. The invention according to claim 3 is an embodiment of a ventilation and lighting section 21 using louver material type A (4A), and corresponds to Figures 7(A), 7(B), 9(A), and 11(B). This is an example included in Example 1. The invention according to claim 4 is an embodiment in which the blocking portion 23 uses the louver material type B (4B), and corresponds to Fig. 10(B). This is an example included in the first embodiment. The invention according to claim 5 is an embodiment in which the blocking portion 23 uses a C-shaped louver material (4C), and corresponds to Fig. 8(C). This is an example included in the first embodiment. The invention according to claim 6 is an embodiment in which a ventilation / screening section 22 using a D-type louver material (8D) is used, and corresponds to FIG. 14. This is an example included in the second embodiment. The invention according to claim 7 is an aspect in which an E-type louver material (8E) is used, and corresponds to Fig. 18. This is an example included in the third embodiment.

[0011] Before describing the examples, the terms used in the present invention will be explained. [Louver material] Louvers are long, thin slats arranged parallel to one another at intervals. They are used in a variety of places for purposes such as sun protection, ventilation, air circulation, privacy, and closure. Louver material 4 refers to the unit components that make up a louver. Louvers generally have long, thin blades that can be separated, and each long, thin blade is a constituent unit, so each blade is called a louver material 4. In louver material type A (4A) in Figure 5(A), louver material type B (4B) in Figure 5(B), louver material type C (4C) in Figure 6, louver material type D (8D) in Figure 14, and louver material type E (8E) in Figure 17, the long, thin blades are the unit components that make up the louver. Each of these becomes a louver material 4.

[0012] [Supporting member] 1 is an explanatory diagram of the base material 95 and the support member 3, consisting of a front view of the louver panel body 2, a cross-sectional view between AA, BB, CC, and DD in the front view, and an enlarged view of the rectangular area E. Louver material type A (4A) is used as a representative example of the louver material 4, and the explanation of FIG. 1 is common to louver material type A (4A) to louver material type C (4C) of Example 1. The louver panel body 2 is formed by connecting multiple louver materials 4, which are unit components, to support members 3 and then unitizing them so that they can be attached directly to the base material 95. The front view and AA cross section of Figure 1 are drawings that explain the role of the intermediate aggregate 86. Multiple louver materials 4 are connected by the intermediate aggregate 86 to form the louver panel body 2, so the intermediate aggregate 86 also plays the role of the support member 3. The louver panel body 2 is assembled in a factory or the like by arranging the louver materials 4 at the designed intervals and fastening them with screws 861 using the intermediate aggregate 86. Although the intermediate aggregate 86 is shown as an example of the support member 3, the shape, structure, attachment position, and number of the support member 3 are not limited as long as the louver members 4 can be attached at predetermined intervals and the louver panel body 2 can be formed. Therefore, various members can fulfill the role of the support member 3 while also having other functions. In the louver material D type (8D) shown in FIG. 15 described later, intermediate aggregate 86 is also used as the support member 3. Furthermore, the mounting bracket 9 in Figure 15(A) functions to attach the louver panel body 2 to the base material 95, but also serves as a support member 3, as it also has the function of connecting each individual louver material D type (8D) to form a unit, as shown in Figure 15(C).

[0013] FIG. 17 is an explanatory diagram of the louver material E type (8E). The louver material type E (8E) has a plurality of inclined surface portions 82 that are modeled after the louver material 4, each of which is connected integrally to the inside of a single panel plate portion 87. In the case of the louver material type E (8E), the plurality of inclined surface portions 82 are integrally molded with the single panel plate portion 87, so the panel plate portion 87 functions as the support member 3. The louver material type E (8E) is also a louver panel body 2 because it is integrally molded with the panel plate portion 87.

[0014] [Base material] The attachment relationship between the base material 95 and the louver material 4 will be described using the front view and the cross-sectional view between CC in FIG. The base material 95 is a member that supports the louver panel body 2, and must be a strong member in order to firmly support the louver elements 4 that are exposed to wind and rain. The base material 95 is preferably an H-shaped steel beam, angle iron, or the like. The louver panel body 2 is made by assembling the louver elements 4 with core members 86 (support members) so that they are spaced at predetermined intervals, so installation is completed by placing the ends of the louver panel body 2 against the base material 95 and fastening each louver element 4 with fastening members 46. Because there are many louver materials 4, it takes time to fasten each one to the base material 95 at the specified intervals. However, because the louver panels 2 are assembled with intermediate framework 86 (support members) so that they are aligned at the designed intervals in advance, work efficiency is high.

[0015] [Horizontal piece] The horizontal pieces are one of the features of the present invention. As shown in the enlarged view of rectangular area E in Figure 1, there is a lower horizontal piece 43 provided at the lower end 8b of the inclined surface portion 41 and an upper horizontal piece 421 provided at the upper end of the louver material 4. Both horizontal pieces affect characteristics such as ventilation, lighting, privacy, and closure.

[0016] [gap] The enlarged view of rectangular area E in Figure 1 is an enlarged view of rectangular area E attached to the B-B cross section. Details of the louver material 4 will be described later, but the louver material 4 of the present invention has an inclined surface portion 41, which is a characteristic of the louver blades. Changing the installation distance between the upper and lower louver materials 4 changes the amount of air blowing from the outside to the inside. There are many gaps involving the lower horizontal piece 43 or the upper horizontal piece 421, which affect the wind blowing in. For example, there is a lower gap 221 formed between the lower horizontal piece 43 of the upper louver material 4 and the upper horizontal piece 421 of the lower louver material 4. Also, it is a ventilation opening 222 (vertical gap) formed between the upper inner side 412 of the inclined surface portion of the louver material 4 above and the upper horizontal piece portion 421 of the louver material 4 below. 2, only when the louver material 4 below is attached at an attachment interval (pitch) such that the rear of the inclined surface portion 41 of the upper louver material 4 is swallowed up by the rear of the inclined surface portion 41 of the upper louver material 4, will the inclined surface portion rear gap 413 be formed between the rear of the inclined surface portion 41 of the upper louver material 4 and the upper horizontal piece portion 421 of the lower louver material 4. In an embodiment in which the upper horizontal piece portion 421 is long, the width of the inclined surface portion rear gap 413 formed between the upper horizontal piece portion 421 and the rear surface of the inclined surface portion 41 becomes smaller, and the amount of air blowing in changes. There are other types of gaps, and the examples above are representative examples. Depending on the installation distance between the upper louver material 4 and the lower louver material 4 and the length of the upper horizontal piece 421 and the lower horizontal piece 43, various gaps are created that affect characteristics such as ventilation, lighting, privacy, and obstruction, and by limiting the width of these gaps, the above characteristics change.

[0017] The present invention also includes louver materials 4 provided with only upper horizontal pieces 421, and louver materials 4 provided with only lower horizontal pieces 43. When the louver materials 4 are attached, the upper horizontal pieces 421 or the lower horizontal pieces 43 have a certain gap width. Of course, the present invention also includes embodiments having both the upper horizontal pieces 421 and the lower horizontal pieces 43.

[0018] These gaps affect properties such as ventilation, lighting, privacy, and obstruction, and which gap has the greatest impact depends on the installation distance between the upper louver material 4 and the lower louver material 4, and the length of the upper horizontal piece 421 and the lower horizontal piece 43. For example, if the width of the ventilation opening 222 (vertical gap) becomes short and is effectively blocked, wind cannot blow in even if the width of the lower gap 221 is large, and a blocked portion 23 is formed. Furthermore, if the width of the lower gap 221 is greatly restricted and there is no room for wind to blow in, it may become a blocked portion 23 even if the width of the inclined surface portion rear gap 413 or the ventilation opening 222 (vertical gap) is wide.

[0019] [Mounting part] The louver materials 4 must be attached to the base material 95. In the present invention, various means for attaching the louver materials 4 to the base material 95 are possible. As shown in the enlarged view of the rectangular area E in FIG. 1 , an attachment portion 45 is provided at the top of the back of the inclined surface portion, and a pocket portion 451 is provided to accommodate a fastener 46, such as a bolt, so that the louver materials 4 can be fastened to the base material 95. The attachment intervals of the louver materials 4 may vary. As shown in FIG. 2 , the louver materials 4 may be attached at an interval such that the upper horizontal piece 421 of the lower louver material 4 is inserted inside the inclined surface portion 41 of the upper louver material 4. If the lower louver material 4 in FIG. 2 is attached further upward, the upper end 8a (upper horizontal piece 421) of the vertical piece 42 of the lower louver material 4 abuts against the inner side 412 of the upper inclined surface portion, which is the underside of the attachment portion 45. This eliminates the ventilation opening 222 (vertical gap), forming a blocked portion 23. The upper end 8a (upper horizontal piece 421) of the vertical piece 42 limits the width of the ventilation opening 222 (vertical gap). The position where the mounting portion 45 is provided does not have to be the inside upper portion 412 of the inclined surface portion. Furthermore, when using the mounting bracket 9 of Example 2 or Example 3 described below, the mounting portion 45 for fastening to the base material 95 is not required. Eliminating the mounting portion 45 expands the area that becomes the ventilation opening 222 (vertical gap).

[0020] [Length of horizontal piece] The lengths of the lower horizontal piece 43 and the upper horizontal piece 421 can be determined appropriately depending on the desired characteristics such as ventilation, lighting, privacy, and closure. For example, in the example of Figure 2, the length of the upper horizontal piece 421 is shorter than the width of the underside of the mounting part 45, so that the upper end 8a (upper horizontal piece 421) of the vertical piece 42 can abut against the underside of the mounting part 45. If the length of the upper horizontal piece 421 is made longer than the underside of the mounting portion 45, the tip of the upper horizontal piece 421 of the lower louver material 4 will abut against the underside of the inclined surface portion 41 of the upper louver material 4 before abutting against the underside of the mounting portion 45, and the gap 413 behind the inclined surface portion will be restricted and disappear, becoming a blocked portion 23. A ventilation opening 222 (vertical gap) will remain between the upper end 8b (upper horizontal piece 421) of the vertical piece 42, but because the gap 413 behind the inclined surface portion becomes a blocked portion 23, ventilation will be lost. The length of the lower horizontal piece 43 can also be varied to affect different gap widths.

[0021] Example 1 Example 1 is an example of a louver panel body 2 provided on a scaffolding 7 provided under or on the side of an elevated structure 5. The scaffolding 7 is an example of a structure 1 on which the louver panel body 2 is provided.

[0022] [Overall scaffolding structure] FIG. 3 is a schematic diagram of Example 1. FIG. 3(A) is a cross-sectional view of the viaduct 5, and FIG. 3(B) is a side view of the viaduct 5. Scaffolding 7 is shown installed under the viaduct 5. Beneath the road surface material 52, under-elevation components such as plate girders 51 that support the road surface material 52 are installed. Work is underway to install the scaffolding 7 between the legs 53, and the cross beams 75 of the scaffolding 7 are connected to and supported by the under-elevation components such as the plate girders 51 via cross beam supports 77. As the scaffolding 7 is extended, louver panel bodies 2 are attached one after another to both the left and right sides of the viaduct 5, completing the structure 1.

[0023] FIG. 4 is a cross-sectional view of the viaduct 5 and an enlarged view of the frame a shown in the cross-sectional view. The scaffolding 7 can be attached to any under-elevation member, but is preferably a strong member such as a box girder or plate girder 51. In Example 1, a plurality of cross beam support members 77 are attached to the plate girder (under-elevation member) 51 to support the cross beam 75 of the scaffolding 7. If there is no strong member above the cross beam 75, as shown in FIG. 4, auxiliary members 774 can be attached to the sides of the plate girder (under-elevation member) 51, and the cross beam support members 77 can be attached. With the auxiliary members 774 attached, the cross beam support members 77 can also be used as a base material 95 for attaching the louver panel body 2.

[0024] The louver material 4 shown in Example 1 has three types as shown in Figures 5 and 6. These are louver material type A (4A), louver material type B (4B), and louver material type C (4C). Figure 5(A) is a side view of louver material type A (4A), Figure 5(B) is a side view of louver material type B (4B), and Figure 6 is a side view of louver material type C (4C). The three types share the following common structure:

[0025] [Slope section] All molds have the inclined surface portion 41 of the same shape and size. It is sufficient that a portion of the inclined surface portion 41 is an inclined surface. In Example 1, the lower end of the inclined surface portion 41 is a vertical surface 411. The vertical surface 411 does not have to exist, and it is preferable that the inclined surface portion 41 is made to stand out in appearance.

[0026] [Mounting part] The mounting portions 45 that form part of the inclined surface portion 41 are all formed to have the same shape and size for all three types. The mounting portions 45 can be positioned as desired, but in Example 1 they are provided on the inside of the inclined surface portion 41. Furthermore, the louver material 4 can be attached by fastening it from the scaffolding 7 side.

[0027] The mounting portion 45 is provided with a pocket portion 451. The pocket portion 451 has a structure that allows insertion of a fastening material 46, such as the head of a nut or bolt, for attaching the louver material 4 to the base material 95. The pocket portion 451 is formed to be approximately the same size as the head of the nut or bolt, and functions as a rotation stopper for the nut or bolt. The pocket portion 451 contributes to improving work efficiency when fastening the louver material 4 to the base material 95. The louver material 4 can be fastened from the base material 95 side (the scaffolding 7 side), and because the fastening material 46 is contained in the pocket portion 451, the fastening material 46 is not exposed on the front side of the louver material 4.

[0028] [Lower horizontal piece] The "lower horizontal piece 43", which is one aspect of the "horizontal piece" of the present invention, will be described. The three types of louver material A type (4A) to louver material C type (4C) described below have a common feature in that they all have a lower horizontal piece portion 43 that extends inward from the lower end 8b of the inclined surface portion 41 of the louver material 4. This feature will be explained using Figure 5(A) for louver material A type (4A) and Figure 5(B) for louver material B type (4B). The lower horizontal piece 43 functions as follows when multiple louver materials 4 are attached vertically to the base material 95 to form louvers. The lower horizontal piece 43 limits the length of the width (ventilation) of the lower gap 221 formed between the lower horizontal piece 43 of the upper louver material 4 and the vertical piece 42 of the lower louver material 4 as seen from the side, as shown in FIG. 5(B). When an upper horizontal piece 421 is provided and the lower horizontal piece 43 and upper horizontal piece 421 face each other, as shown in FIG. 5(A), the lower gap 221 is formed between the lower horizontal piece 43 of the upper louver material 4 and the upper horizontal piece 421 of the lower louver material 4.

[0029] [Top horizontal piece] All three types have upper horizontal pieces 421 that extend outward from the upper end (upper end 422 of the vertical piece) of the louver material 4. Like the lower horizontal pieces 43 described above, when multiple louver materials 4 are attached in the vertical direction to the base material 95 to form louvers, the upper horizontal pieces 421 affect the width of the lower gap 221 that is formed between the upper louver material 4 and the upper horizontal piece 421 of the louver material 4 below it in side view, and thus affect the ventilation between the louver materials 4. In addition, the upper horizontal piece 421 of the lower louver material 4 forms part of the ventilation opening 222 (vertical gap) between it and the upper inner side 412 of the inclined surface portion of the upper louver material 4, i.e., on the back side of the louver material 4, and limits ventilation. In the case of a louver material 4 that does not have a lower horizontal piece 43, the upper horizontal piece 421 of the lower louver material 4 will limit the width of the ventilation opening 222 (vertical gap) created between it and the upper inner side 412 of the inclined surface portion 41 of the upper louver material 4 when viewed from the side. That is, the lower horizontal piece 43 and the upper horizontal piece 421 together limit the width dimension of the lower gap 221 in the projection direction and the width of the ventilation opening 222 (vertical gap), which is a gap in the vertical direction.

[0030] [Louver material type A] Louver material type A (4A) is the most basic type. Of the three types, it has the shortest vertical piece 42. Here, "short" means a length shorter than the vertical dimension of the inclined surface portion 41. The vertical piece 42 extends upward from the upper end of the inclined surface portion 41, and is designed to fit along the base material 95 when attached to the base material 95. The lower horizontal piece 43 is a short member that extends inward from the lower end 8b of the inclined surface portion 41. Here, "short" means a short length that creates a lower gap 221 through which air can pass between the base material 95 and the lower horizontal piece 43 when the louver material type A (4A) is attached to the base material 95. Although the lower horizontal piece 43 is short, it has the effect of restricting ventilation when attached to the base material 95.

[0031] The louver material type A (4A) also has an upper horizontal piece 421 that extends outward from the upper end 422 of the vertical piece, which is the upper end of the louver material type A (4A). When multiple louver materials type A (4A) are attached in the vertical direction to the base material 95 to form the louver panel body 2, this affects the width of the lower gap 221 that is formed between the lower horizontal piece 43 of the upper louver material type A (4A) in side view and the upper end of the louver material type A (4A) below it, i.e., the upper end 422 of the vertical piece (upper horizontal piece 421). In this way, both the lower horizontal piece 43 and the vertical piece upper end 422 (upper horizontal piece 421) limit the ventilation between the upper louver material A-type (4A) and the lower louver material A-type (4A) when viewed from the side. Even in an embodiment where only one of the lower horizontal piece 43 and the vertical piece upper end 422 (upper horizontal piece 421) is present, the function of limiting the width of the lower gap 221 is not lost.

[0032] When multiple type-A louver materials (4A) are attached vertically to the support member 3 to form the louver panel body 2, the upper horizontal pieces 421 extending outward from the upper ends 422 of the vertical pieces, which are the upper ends of the type-A louver materials (4A), perform the following function: Between the upper louver material type-A (4A) and the lower louver material type-A (4A), ventilation openings 222 (vertical gaps) are created on the upper and lower back sides. The upper ends 422 of the vertical pieces (upper horizontal pieces 421) of the lower type-A louver material (4A) form part of the ventilation openings 222 (vertical gaps), and limit the ventilation of air entering the interior through the ventilation openings 222 (vertical gaps). As described above, the lower horizontal piece 43 and the upper horizontal piece 421 restrict ventilation and mainly affect the privacy, ventilation, and lighting.

[0033] When the louver material type A (4A) is installed with the vertical piece 42 of the louver material type A (4A) below it spaced apart from the lower horizontal piece 43 of the louver material type A (4A) above, the lower horizontal piece 43 is short and the width of the lower gap 221 is wide, so that the type has high ventilation, allowing air to pass through from the inside of the inclined surface portion 41. Details will be described later, but the louver material type A (4A) can be used as a ventilation / lighting section 21 and a ventilation / screening section 22 by adjusting the installation interval. At this time, the upper horizontal piece 421, together with the lower horizontal piece 43, limits the width of the lower gap 221, making it difficult to see inside the louver panel body 2, thereby helping to improve its function as a privacy screen.

[0034] [Louver material type B] Comparing louver material type A (4A) in Figure 5(A) with louver material type B (4B) in Figure 5(B), louver material type B (4B) differs from louver material type A (4A) only in that the length of the lower horizontal piece portion 43 is longer than that of louver material type A (4A). Like the type A louver material (4A), the type B louver material (4B) has an upper horizontal piece 421 extending outward at its upper end (upper end 422 of the vertical piece). Details will be given later, but louver material type B (4B) has a higher blocking effect than louver material type A (4A) even when the installation spacing (pitch) is changed.

[0035] When louver material type B (4B) is installed above and below, the lower horizontal piece 43 of louver material type B (4B) is significantly longer than that of louver material type A (4A), so the width of the lower gap 221 formed between the lower horizontal piece 43 of louver material type B (4B) above and the vertical piece 42 of louver material type B below in side view becomes smaller, and ventilation through the lower gap 221 is significantly restricted. Since the louver material type B (4B) has a long lower horizontal piece 43, even if it is installed apart from the top and bottom so that it does not overlap, almost no wind passes inside the inclined surface portion 41. The louver material type B (4B) is a type that places emphasis on blocking properties, and can be used as a ventilation / lighting section 21 or a blocking section 23 by adjusting the installation interval.

[0036] [Louver material C type] FIG. 6 is a side view of the louver material C-type (4C), which differs from the louver material A-type (4A) only in that the length of the vertical piece portion 42 is longer. The lower horizontal piece 43 of the C-type louver material (4C) is short like the A-type louver material (4A) (a short length that leaves a lower gap 221 below the C-type louver material (4C) through which air can pass). The length of the vertical piece 42 extending upward from the upper end of the inclined surface portion 41 is longer than the vertical dimension of the inclined surface portion 41. The louver material C type (4C) has longer vertical pieces 42 than the louver material A type (4A), so it has a high blocking effect even when the vertical installation interval is increased. As will be described in more detail later, this type is characterized by the fact that it can be used as any of the ventilation / lighting section 21, ventilation / screening section 22, or blocking section 23 by adjusting the vertical installation interval (pitch).

[0037] In particular, because the vertical pieces 42 of the C-type louver material (4C) are long, the position of the upper ends 422 of the vertical pieces (upper horizontal pieces 421) is high, which significantly limits the width of the ventilation opening 222 (vertical gap) created on the back side of the C-type louver material (4C), which leads to the inside through the upper ends 422 (upper horizontal pieces 421) of the C-type louver material (4C) above and the C-type louver material (4C) below in side view. With the C-type louver material (4C), even if the width of the lower gap 221 is large, the width of the ventilation opening 222 (vertical gap) tends to be small, making this a type of louver material 4 that emphasizes privacy and obstruction.

[0038] (Other type variations) The louver material 4 may be of various types other than the louver material type A (4A), louver material type B (4B), and louver material type C (4C) presented as examples. What is common to each type of louver material 4 that makes up the louver panel body 2 is the lower horizontal piece 43 or the upper horizontal piece 421, and by varying the length of this, variations can be increased. Even if only one type of louver material 4 is used, by changing the installation interval (pitch), it is possible to create a louver panel body 2 equipped with ventilation / lighting sections 21 that have different levels of ventilation and lighting properties.

[0039] [Installation example] Below, examples of how to attach each type of louver material 4 to scaffolding 7 are shown, but attachment methods other than the examples are not excluded and are shown as examples only.

[0040] Figure 7 is a diagram showing an example of installation of the louver material type A (4A). In the example of Figure 7, all of the louver materials type A (4A) in the drawing are the same, and the vertical dimension is 60 mm.

[0041] FIG. 7(A) is a side view showing an example of mounting a comparison standard, FIG. 7(B) is a side view showing an example of mounting with a wider mounting interval (pitch), and FIG. 7(C) is a side view showing an example of mounting with a narrower mounting interval (pitch). Note that Figure 7(A) is a comparison reference diagram for explaining the influence of the installation interval (pitch). The installation interval (pitch) shown in Figure 7(A) is not a recommended standard, nor is it a preferred installation interval (pitch). The optimal installation interval (pitch) for the louver materials 4 will vary depending on the surrounding environment of the location where the louver materials 4 are to be installed, the desired lighting, and other factors.

[0042] Please refer to Figure 7(A) and an enlarged view of a portion thereof. This is the same for all types of louver panel bodies 2, but the side of the inclined surface portion 41 relative to the base material 95 is the outside, and the side facing the scaffolding 7, separated by the base material 95, is the inside. The lower horizontal piece 43 of the upper louver material Type A (4A) and the vertical piece 42 of the lower louver material Type A (4A) are attached so that they are spaced apart when viewed from the front. The daylight opening 213 created between the spaced-apart upper and lower louver materials Type A (4A) is set to 10 mm. Wind and light enter the inside of the scaffolding 7 through this daylight opening 213, but the inside can be seen through the daylight opening 213, so the inside cannot be concealed.

[0043] The vertical mounting distance of the louver material type A (4A) to the base material 95 can be measured as the distance between the lower horizontal piece 43 of the louver material type A (4A) above and the lower horizontal piece 43 of the louver material type A (4A) mounted below, and in this mounting example is 70 mm. Furthermore, the plurality of type A louver materials (4A) form a daylight opening 213 between the lower horizontal piece 43 of the upper type A louver material (4A) and the upper end 422 (upper horizontal piece 421) of the vertical piece of the lower type A louver material (4A) in side view. Furthermore, a type A louver material (4A) ventilation opening 222 (vertical gap) that leads to the inside of the scaffolding 7 is formed between the upper inside 412 of the inclined surface part of the upper louver material (4A) and the upper end 422 (upper horizontal piece 421) of the vertical piece of the lower louver material (4A), and part of this becomes the daylight opening 213. This installation example is an installation example of louver material type A (4A) which becomes the ventilation and lighting section 21.

[0044] Figure 7(B) is an installation example that emphasizes ventilation and light transmission. This installation example in Figure 7(B) is an installation example of louver material type A (4A) which forms the same ventilation and light transmission section 21 as Figure 7(A) above, but the vertical installation spacing of the louver material type A (4A) relative to the base material 95 is wider at 80 mm than in Figure 7(A), and the light transmission opening 213 is wider at 20 mm than in Figure 7(A). Compared to the comparison standard in Figure 7(A), the performance of concealment, rain intrusion prevention, and object fall prevention is reduced, but ventilation and light transmission are improved. Figure 7(B) is brighter and more airy, improving the work environment compared to the comparison standard in Figure 7(A).

[0045] Figure 7(C) shows an installation example that prioritizes preventing rain from entering and objects from falling. The vertical installation distance of the louver material Type A (4A) to the base material 95 is such that the lower horizontal piece 43 of the upper louver material Type A and the vertical piece 42 of the lower louver material Type A (4A) overlap in a front view. In terms of overlap, this is a negative value of -10 mm, and the upper end 422 (upper horizontal piece 421) of the vertical piece of the lower louver material Type A (4A) is swallowed up inside the inclined surface portion 41 of the upper louver material Type A (4A). For this reason, there is no daylight opening 213 that allows direct viewing of the inside of the louver panel body 2 when viewed from the front, as shown in Figure 7(B). The daylight opening 213 has disappeared, but a lower gap 221 is created between the lower horizontal piece 43 of the upper louver material A-type (4A) in side view and the upper end 422 (upper horizontal piece 421) of the vertical piece of the louver material A-type (4A) in side view. And, a ventilation opening 222 (vertical gap) leading to the inside of the scaffolding 7 is created between the upper inside 412 of the inclined surface part of the upper louver material A-type (4A) in side view and the upper end 422 (upper horizontal piece 421) of the vertical piece of the louver material A-type (4A) in side view.

[0046] Therefore, the wind that enters through the lower gap 221 enters the inside of the inclined surface portion 41 as shown by the arrow, and can enter the scaffolding 7 (inside) through the ventilation opening 222 (vertical gap). Although the ventilation opening 222 (vertical gap) is narrower than that of the comparison standard, Figure 7 (A), it still has ventilation, but it serves as a ventilation and concealment section where the inside cannot be seen from the front. The above has explained the installation interval (pitch) of louver material type A (4A), but the installation interval (pitch) of louver material type B (4B) and louver material type C (4C) can also be changed appropriately.

[0047] [Installation example with matching appearance] Fig. 8 is an explanatory diagram of appearance matching. The vertical dimension of the louver material type A (4A) and the louver material type B (4B) in Fig. 8 is 60 mm, and that of the louver material type C (4C) is 80 mm. The attachment interval (pitch) of the louver materials 4 can be expressed as the distance between the lower horizontal piece 43 of one louver material 4 and the lower horizontal piece 43 of the louver material 4 attached below it. Fig. 8(A) shows a louver panel body 2 using type A louver material (4A), in which the type A louver material (4A) is attached at an attachment interval (pitch) of 70 mm to form a 10 mm light-collecting opening 213, forming a ventilation / lighting section 21. In side view, a lower gap 221 is formed between the lower horizontal piece 43 of the upper type A louver material (4A) and the upper end 422 (upper horizontal piece 421) of the vertical piece of the lower type A louver material (4A). The ventilation opening 222 (vertical gap) on the back side of the louver material 4A is large, providing good ventilation.

[0048] 8(B) shows a louver panel body 2 using louver material type B (4B), and is an example of installation in which louver material type B (4B) is installed at an installation interval (pitch) of 70 mm to form a 10 mm light opening 213, forming ventilation and lighting section 21. Louver material type B (4B) has a lower horizontal piece 43 that extends inward from the lower end 8b of inclined surface portion 41 to a position approximately directly below vertical piece portion 42. Because the lower horizontal piece 43 of the type B louver material (4B) is long, no matter what the installation interval (pitch) is, the width of the lower gap 221 that forms between the upper louver material type B (4B) and the lower louver material type B (4B) below it in a side view is significantly limited. The long lower horizontal piece 43 of the type B louver material (4B) only allows a small amount of air to pass inside the inclined surface portion 41 of the type B louver material (4B), and essentially blocks the area where the type B louver material (4B) is installed. The area that functions as the ventilation and lighting section 21 is limited to the ventilation opening 222 (vertical gap) between the lower horizontal piece 43 of the upper louver material type B (4B) and the upper end 422 of the vertical piece of the lower louver material type B (4B). The installation example of louver material type A (4A) in Figure 8(A) and the installation example of louver material type B (4B) in Figure 8(B) are common installation examples that serve as ventilation and lighting section 21, but the installation example in Figure 8(A) prioritizes ventilation, while the installation example in Figure 8(B) prioritizes wind protection. The installation example in Figure 8(B) can be used for scaffolding 7 under bridges that are often exposed to strong winds.

[0049] The louver panel body 2 using the louver material type A (4A) with a vertical dimension of 60 mm in Figure 8(A) and the louver material type B (4B) with a vertical dimension of 60 mm in Figure 8(B) both have a 10 mm daylight opening 213 at an installation interval (pitch) of 70 mm. The intervals of the inclined surface portions 41, which are noticeable from the outside, are exactly the same, making them indistinguishable at a glance.

[0050] FIG. 8(C) shows a louver panel body 2 using C-type louver materials (4C), which are attached at a 60 mm attachment interval (pitch). In Example 1, the louver panel is designed so that the upper horizontal piece 421 at the upper end 422 of the vertical piece of the lower C-type louver material (4C) abuts the inner upper inclined surface 412 where the attachment portion 45 of the upper C-type louver material (4C) is located. Therefore, simply by attaching the vertical piece 42 of the lower C-type louver material (4C) to the attachment portion 45 of the upper C-type louver material (4C), the louver panels can be attached at a 60 mm interval (pitch). The vertical dimension of the C-type louver material (4C) is 80 mm, but the vertical piece 42 of the lower C-type louver material (4C) is inserted into the inner side of the upper inclined surface 41, resulting in an overlap of -20 mm. The installation example in Figure 8 (C) is an installation example in which the mounting portion 45 on the inside of the inclined surface portion 41 of the upper louver material C-type (4C) and the vertical piece portion 42 of the lower louver material C-type (4C) are arranged to abut against each other, thereby eliminating the ventilation opening 222 (vertical gap) on the back side of the louver material C-type (4C), resulting in a blocked portion 23 that has no ventilation or lighting properties. Compared to the louver material C type (4C) in Figure 8(C) with an installation interval (pitch) of 60 mm, the louver material A type (4A) in Figure 8(A) and the louver material B type (4B) in Figure 8(B) with an installation interval (pitch) of 70 mm, when placed side by side, there is a discrepancy in appearance that is obvious, but it is not very noticeable. Furthermore, if a louver panel body 2 of the louver material A type (4A) in Figure 8(A) is placed below and a louver panel body 2 of the louver material C type (4C) in Figure 8(C) is placed above, the difference in appearance becomes less noticeable.

[0051] In a louver panel body 2 in which the attachment intervals (pitch) of louver material type A (4A) to louver material type C (4C) are the same, even if different types of louver panel bodies 2 are lined up on the left and right, the positions of the inclined surface portions 41 will match in appearance, making them indistinguishable. By simply adjusting the installation interval (pitch), the same appearance can be achieved regardless of the type of louver material 4 used.

[0052] [Mounting interval (pitch) change] Figure 9 is an explanatory diagram of changing the installation interval (pitch). By combining the type of louver material 4 used and the installation interval (pitch), it is possible to appropriately adjust the lighting, ventilation, privacy, and obstruction properties. Figure 9(A) shows an example of a ventilation / lighting section 21 using louver material type A (4A) with an installation interval of 80 mm. The daylight opening 213 is wider, 20 mm, than in Figure 8(A). Because the installation interval (pitch) is wider than in Figure 8(A), more light enters the inside of the louver panel body 2. Both the installation examples in Figures 8(A) and 9(A) use louver material type A (4A) to create a ventilation / lighting section 21, but by widening the installation interval in the example of Figure 9(A), it is possible to improve lighting and ventilation compared to the example of Figure 8(A).

[0053] Also, Figure 9(B) is an example of installation using louver material type C (4C) with an installation interval of 80 mm to form ventilation and privacy sections 22. As mentioned above, if the installation interval (pitch) of louver material type A (4A) to louver material type C (4C) is the same, the positions of the inclined surface sections 41 will be aligned. The appearance of Figure 9(A) using louver material type A (4A) and Figure 9(B) using louver material type C (4C) is almost the same despite the use of different types of louver material 4, as the installation interval (pitch) is the same, 80 mm, the intervals of the inclined surface sections 41 are aligned.

[0054] [Gap restriction by upper and lower horizontal pieces] Various installation examples of louver materials A type (4A) to C type (4C) have been explained above. The restriction of the gap by the upper horizontal piece 421 and the lower horizontal piece 43 will now be explained in detail. As mentioned above, the upper horizontal piece 421 and the lower horizontal piece 43 are both elements that make up the lower gap 221, and having either one of them can restrict the width of the lower gap 221. Furthermore, if the length of the upper horizontal piece 421 or the lower horizontal piece 43 is increased, the width of the lower gap 221 will be narrowed. Furthermore, the upper horizontal piece 421 limits the width of the ventilation opening 222 (vertical gap) by changing the attachment interval of the louver material 4.

[0055] The present invention encompasses any louver having either the upper horizontal piece 421 or the lower horizontal piece 43. Example 1 is an example having both the upper horizontal piece 421 and the lower horizontal piece 43. When the lower horizontal piece 43 is extremely long, as in the case of louver material type B (4B), the lower gap 221 is greatly restricted regardless of the installation interval, and wind is effectively prevented from entering the inside of the inclined surface portion 41. Furthermore, in the case of louver material C-type (4C) which has a long vertical piece 42 with an upper horizontal piece 421, the ventilation opening 222 (vertical gap) is greatly restricted, and when the upper inner side 412 of the inclined surface part of the louver material C-type (4C) on the top and the lower upper horizontal piece 421 of the louver material C-type (4C) on the bottom are installed at an abutting distance, wind will not actually enter the inside through the ventilation opening 222 (vertical gap). As shown in Figure 9(A), when the upper and lower louver materials A-type (4A) are installed at a distance from each other, the width of the lower gap 221 and the width of the ventilation opening 222 (vertical gap) both become larger, forming a ventilation and lighting section 21. By restricting the gap between the upper horizontal piece 421 and the lower horizontal piece 43, various louver panel bodies 2 can be created, with emphasis on ventilation or wind protection.

[0056] FIG. 10 is an explanatory diagram of changes in the mounting interval (pitch). Figure 10(A) shows an example of installation using louver material type A (4A) with an installation interval (pitch) of 60 mm, the same as the vertical dimension of the louver material 4, as the ventilation / privacy section 22. The lower horizontal piece 43 of the upper louver material type A (4A) is attached to the base material 95 so that it overlaps with the vertical piece 42 of the lower louver material type A (4A) in a front view. In addition, in this installation example, the lower horizontal piece 43 of the upper louver material type A (4A) and the upper end 422 of the vertical piece of the lower louver material type A (4A) are attached to the base material 95 so that they are in approximately the same position in a side view. When viewed from the side, a lower gap 221 is left between the upper end 422 of the vertical piece and the lower horizontal piece 43, and a ventilation opening 222 (vertical gap) is left between the upper end 422 of the vertical piece of the lower louver material type A (4A) and the upper inside 412 of the inclined surface part of the upper louver material type A (4A), thereby providing ventilation but forming a ventilation / concealment part 22 in which the inside cannot be seen from the front.

[0057] Figure 10(B) is an example of installation using louver material type B (4B) with an installation interval (pitch) of 60 mm to form blocking section 23. The installation interval (pitch) of louver material type B (4B) in the vertical direction relative to base material 95 is such that the vertical piece 42 of the lower louver material type B (4B) and the tip of the lower horizontal piece 43 of the upper louver material type B (4B) overlap in side view to form blocking section 23.

[0058] Furthermore, even if the installation interval (pitch) of the louver material type B (4B) is further narrowed to 50 mm and the upper end 422 of the vertical piece of the lower louver material type B (4B) is installed so that it is swallowed up inside the inclined surface portion 41 of the upper louver material type B (4B), it will still essentially become a blocking portion 23. The appearance of Figure 10(A) using louver material type A (4A) and Figure 10(B) using louver material type B (4B) is the same because the installation intervals (pitch) are the same, so the spacing of the inclined surface portions 41 is the same, and the appearance is the same despite the use of different types of louver material 4.

[0059] [Flexibility] As mentioned above, the present invention has three types of louver materials 4, and the installation interval (pitch) of each type of louver material 4 can be changed, so the size of the ventilation / lighting section 21 can be changed to prioritize ventilation or lighting. If ventilation is desired but a privacy function is also desired, the ventilation / privacy section 22 can be used to prevent rain from entering. If priority is given to preventing objects from falling or shielding, the blocking section 23 can be used.

[0060] The present invention can provide a louver panel body 2 suitable for various situations and locations, such as a bridge exposed to strong winds and rain where wind protection and obstruction are important, a location close to a sidewalk where privacy is important, or a location where lighting is important to improve workability. Furthermore, even if the characteristics are changed, the shape of the inclined surface portion 41 remains the same, so a unified appearance can be achieved.

[0061] Figure 11 is an explanatory diagram of versatility. Figure 11(A) is an example of installation of louver material type A (4A) as a comparison standard, which serves as a ventilation and lighting section 21. The installation interval (pitch) is 70 mm. Note that this is a comparison standard to explain versatility, and is not intended as a preferred or recommended example.

[0062] Figure 11(B) is a side view of the louver panel body 2 in which the installation interval (pitch) has been increased by 80 mm. The same louver material Type A (4A) as the comparison standard is used. The installation interval (pitch) has been changed and widened compared to the comparison standard, so it is no different from the comparison standard in that it has become a ventilation and light section 21. However, the installation example in Figure 11(B) has improved the light and ventilation properties of the louver panel body 2 by the amount of the wider installation interval (pitch).

[0063] Figure 11(C) is a side view of the louver panel body 2 with the installation interval (pitch) narrowed to 50 mm. The same louver material Type A (4A) as the comparison standard is used. Since the installation interval (pitch) has been narrowed compared to the comparison standard, the louver panel body 2 becomes a ventilation and privacy section 22.

[0064] Figure 11(D) is a side view of the louver panel body 2 with a modified shape. The louver panel body 2 in Figure 11(D) uses type C louver material (4C), and the comparison standard and shape have been changed. The installation interval (pitch) is 70 mm, the same as the comparison standard, but because the shape has been changed, the louver panel body 2 has a closed section 23.

[0065] Figure 11(E) is a side view of a louver panel body 2 in which different installation intervals (pitch) are used depending on the height. Both the upper and lower parts of the louver panel body 2 have in common the use of Type A louver material (4A), but the installation interval (pitch) at the upper part is wider at 70 mm and narrower at the lower part at 50 mm. The installation interval (pitch) at the lower part is 50 mm, which is narrower than the vertical dimension of Type A louver material (4A) which is 60 mm, so 10 mm is pushed inside the inclined surface portion 41 of the upper Type A louver material (4A), resulting in a -10 mm interval. Therefore, the upper part serves as a ventilation and lighting section 21, and the lower part serves as a ventilation and privacy section 22. When changing the mounting interval (pitch) in the vertical direction, it is preferable to change it gradually, as this will make the change in appearance less noticeable.

[0066] Figure 11(F) is a side view of a louver panel body 2 in which different types are used depending on the height. The installation interval (pitch) of the louver materials 4 is the same at both the top and bottom of the louver panel body 2, but louver material type A (4A) is used at the top and louver material type B (4B) is used at the bottom. Therefore, the top serves as a ventilation and lighting section 21, while the bottom serves as a ventilation and lighting section 21 that prioritizes wind protection.

[0067] [Using different shapes and spacing for the upper and lower louver panels] FIG. 12 is an explanatory diagram showing how the upper and lower louver panel bodies 2 are used separately. In Figure 12(A), the installation interval (pitch) is slightly wider, with the upper part being a ventilation and lighting section 21 made of louver material type A (4A) and the lower part being a ventilation and privacy section 22 made of louver material type C (4C). In the case of scaffolding 7 under an elevated structure 5, the upper part can be used when priority is placed on lighting so that the underside of the elevated structure 5 can be easily inspected.

[0068] In Figure 12(B), the installation interval (pitch) is slightly narrower, with the upper part being a ventilation and screening section 22 made of louver material type A (4A) and the lower part being a blocking section 23 made of louver material type B (4B). In the case of scaffolding 7 under the elevated structure 5, the lower part can be used when emphasis is placed on blocking, so that tools and concrete fragments resulting from deterioration of the elevated structure 5 do not fall.

[0069] In both Figures 12(A) and 12(B), different louver materials 4 are used on the top and bottom of the louver panel body 2, but the inclined surface portions 41 are aligned, giving the appearance a unified appearance. In addition, their functions differ, such as lighting and blocking, and the degree of ventilation also differs, but the inclined surface portions 41 are the same and the appearance is almost the same.

[0070] [A mode in which the left and right louver panels are used in different shapes and with different spacing] FIG. 13 is an explanatory diagram showing how the left and right sides of the louver panel body 2 are used separately. In Figure 13(A), the installation interval (pitch) is slightly wider, with the left part being a blocking section 23 of C-type louver material (4C) and the right part being a ventilation and lighting section 21 of A-type louver material (4A).

[0071] In Figure 13 (B), the installation interval (pitch) is slightly narrower, with the left part being a blocking section 23 of louver material type B (4B) and the right part being a ventilation and screening section 22 of louver material type A (4A). In both Figures 13(A) and 13(B), different louver materials 4 are used on the left and right sides of the louver panel body 2, but the inclined surface portions 41 are aligned, resulting in a unified appearance.

[0072] The louver material type A (4A) can be installed at different intervals (pitch) to create a ventilation / lighting section 21 and a ventilation / screening section 22. The louver material type B (4B) can be installed at different intervals (pitch) to form a ventilation / lighting section 21 and a blocking section 23. The C-type louver material (4C) can be used as any of a ventilation / lighting section 21, a ventilation / screening section 22, and a blocking section 23 by changing the installation interval (pitch). By changing and attaching the ventilation / lighting section 21, ventilation / screening section 22, and blocking section 23 made of these types of louver materials 4 in the vertical or horizontal directions, it is possible to create a louver panel body 2 that is suited to the environment and the type of work being done.In addition, it is possible to create a structure 1 equipped with such a louver panel body 2.

[0073] [Louver material combination] There are various possible variations, such as selecting at least two types from the above louver material type A (4A), louver material type B (4B), and louver material type C (4C) and attaching them alternately to the top and bottom of the louver panel body 2. It is also possible to use three types of louver material 4, with the lower part being a closed section 23 and gradually changing to a ventilation and lighting section 21 as it moves upward.

[0074] In the first embodiment of the present invention, it has been described that the louver material 4 has an inclined surface portion 41 that is common to each type, and that louver materials 4 are prepared with different dimensions for the vertical piece portion 42 and / or the lower horizontal piece portion 43. By using different types of louver material 4, the present invention makes it possible to uniform the appearance of the ventilation / lighting portion 21, ventilation / screening portion 22, and blocking portion 23 while keeping the installation interval (pitch) uniform.

[0075] Furthermore, in Example 1 of the present invention, it has been shown that the degree of ventilation and lighting of the ventilation / lighting section 21 and the ventilation / privacy section 22 can be changed by changing the installation interval (pitch) of the louver material 4, and that the appearance can be made the same by using different shapes. It goes without saying that four or more types of louver materials 4 may be prepared as long as they have a common inclined surface portion 41.

[0076] Example 2 [D-type louver material] The louver materials 4 of the louver materials A-type (4A) to C-type (4C) of Example 1 each had both an upper horizontal piece 421 and a lower horizontal piece 43. FIG. 14 is a side view of the louver material D-type (8D). As shown, the louver material D-type (8D) of Example 2 has an upper horizontal piece 84 at the upper end 8a of the vertical piece 88, but does not have a lower horizontal piece 43 at the lower end 8b of the inclined surface 82. When multiple louver materials D-type (8D) are attached vertically to form a louver panel body 2, the width of the lower gap 827 formed between the inside of the inclined surface 82 of the upper louver material D-type (8D) in side view and the upper horizontal piece 84 at the upper end 8a of the lower louver material D-type (8D) is limited. By lengthening the upper horizontal piece 84, the width of the lower gap 827 is limited and narrowed. In Figure 14, the lower end 8b of the inclined surface portion 82 of the upper louver material D-type (8D) faces the upper horizontal piece portion 84 (upper end 8a) of the lower louver material D-type (8D), so a lower gap 827 is formed at the position shown in the figure. If the upper horizontal piece portion 84 of the lower louver material D-type (8D) is swallowed up inside the inclined surface portion 82 of the upper louver material D-type (8D), a lower gap 827 is formed between the upper horizontal piece portion 84 and the opposing inclined surface portion 82. The upper horizontal piece 84 limits the width of the lower gap 827 between the upper louver material 4 and the lower louver material 4 when viewed from the side.

[0077] The upper horizontal piece 84 (upper end 8a) also limits the width of the ventilation opening 826 (vertical gap) formed between the lower end 811 of the hanging piece of the upper D-shaped louver material (8D) and the upper horizontal piece 84 (upper end 8a) of the lower D-shaped louver material (8D). The installation interval (pitch) affects the ability to hide, ventilate, and let in light.

[0078] The D-type louver material (8D) also has an inclined surface portion 82 that slopes outward. The inclined surface portion 82 has an area that is configured in this order from the top: an upper inclined surface 821, an upper vertical surface 824, a middle inclined surface 822, and a lower vertical surface 825. A tapping hole 823 is provided on the inside of the middle inclined surface 822 for attaching the D-type louver material (8D) to a mounting bracket 9, which will be described later. As shown in FIG. 15, the mounting bracket 9 also functions as a support member 3 when used to connect D-type louver materials (8D), which are unit components of the louver, from the side to form a unit. A vertical piece 88 extends upward and a hanging piece 81 extends downward, continuing from the upper inclined surface 821. An upper horizontal piece 84 extending outward is provided at the upper end 8a of the vertical piece 88. There is a space 83 surrounded by the upper inclined surface 821, the upper vertical surface 824, and the hanging piece 81. This space 83 is where the tips of the screws 861 for attaching the intermediate aggregate 86 (support member) described later are accommodated.

[0079] The multiple D-type louver materials (8D) are attached in a vertical line using mounting brackets 9, which will be described in Fig. 15, along the direction shown by the dashed lines in Fig. 14. In the attachment mode of Fig. 14, the attachment intervals of the D-type louver materials (8D) are such that the upper and lower D-type louver materials (8D) overlap when viewed from the front, and are attached at intervals such that a ventilation opening 826 (vertical gap) leading to the inside is left between the upper and lower D-type louver materials (8D) when viewed from the side.

[0080] In side view, a lower gap 827 is formed between the upper louver material D-type (8D) and the lower louver material D-type (8D), and wind blows in from the outside to the inside as shown by the arrow. Also, the inside cannot be seen from the outside, so there is ventilation but the inside cannot be seen from the outside, forming a ventilation / screen section 22. In Example 2, the lower end 8b of the upper louver material D-type (8D) and the upper end 8a of the lower louver material D-type (8D) are installed at an interval (pitch) such that they exactly overlap when viewed from the front, and this is the installation interval that maximizes the width of the ventilation opening 826 (vertical gap) in the form of a ventilation / privacy section 22. If it is desired to suppress ventilation, it is possible to narrow the width of the ventilation opening 826 (vertical gap) by narrowing the mounting interval (pitch).

[0081] [Mounting bracket holding part] Figure 15 is an explanatory diagram of the installation of D-type louver material (8D), Figure 15(A) is an explanatory diagram of the louver panel body 2 and mounting bracket 9, Figure 15(B) is an enlarged view of the area within box a in Figure 15(A), and Figure 15(C) is a cross-sectional view between AA in Figure 15(A). Since each D-type louver material (8D) is attached to the central frame 86 and mounting bracket 9 at a predetermined interval to form the louver panel body 2, the mounting bracket 9 as well as the central frame 86 can also be considered a support member 3. In this way, the support member 3 may also have other functions, like the mounting bracket 9. The mounting bracket 9 may be attached at the time of construction on-site or may be attached at the factory. The mounting bracket 9 can be fixed to an appropriate member of the scaffolding 7 under the elevated structure 5. In Example 2, however, an H-shaped steel beam is attached to the girder (lower elevated structure member) 51 via a support member 774 as the base member 95 (see the enlarged view of box a in FIG. 4). The mounting bracket 9, shown hatched in FIG. 15(B), is a long metal fitting that allows multiple D-shaped louver members (8D) to be attached in the vertical direction, and forms the side of the louver panel body 2. The mounting bracket 9 also has a holding portion 91 that holds the side of the D-shaped louver member (8D). The holding portion 91 is composed of three regions: a protrusion 911, a recessed wall portion 913, and an abutment portion 93. The recessed wall portion 913 of the holding portion 91 covers the side of the D-shaped louver member (8D) and has a tapping screw 912 that is driven from the recessed wall portion 913 toward the side of the D-shaped louver member (8D). A tapping hole 823 is provided on the inside of the inclined surface portion 82 of the D-type louver material (8D). The louver material is attached to the mounting bracket 9 by driving a tapping screw 912 from the recessed wall portion 913 into the tapping hole 823 of the D-type louver material (8D).

[0082] When louver panel bodies 2 using mounting brackets 9 are attached to a structure 1 side by side, it is preferable that the tapping screws 912 of the right and left louver panel bodies 2 be attached so that they face and abut each other, as shown in Figure 15(A). By having the tapping screws 912 in the same position face and abut each other, it is possible to prevent the tapping screws 912 from loosening.

[0083] The abutment portion 93 connected to the recessed wall portion 913 may have a shape like a protrusion or ridge, and does not have to be a surface. The side wall (attached portion) of the D-type louver material (8D) is sandwiched between the abutment portion 93 connected to the recessed wall portion 913 and the protrusion 911, thereby embracing the side wall of the D-type louver material (8D). When the D-type louver material (8D) is exposed to wind and the side wall is embracing it, a force is generated that tries to rotate it around the tapping screw 912 as an axis, but the abutment portion 93 and protrusion 911 that sandwich the D-type louver material (8D) can resist this force.

[0084] Any suitable attachment means may be used to attach the D-type louver material (8D) to the embracing portion 91. For example, a side wall (attachment portion) may be provided on the D-type louver material (8D), and the side wall and the projection wall portion 913 may be fastened together with a fastener.

[0085] [Mounting bracket contact part] 15(B) shows an enlarged view of the abutment portion 93 and groove portion 92. The mounting bracket 9 has the abutment portion 93 connected to the recessed wall portion 913. The abutment portion 93 may abut against the vertical piece portion 88 of the D-type louver material (8D), or may abut against the hanging piece portion 81, or may abut against only one or both.

[0086] [Groove] The mounting bracket 9 has a groove 92 adjacent to an abutment portion 93 that connects to the recessed wall portion 913. The groove 92 is for attaching the mounting bracket 9 to the base material 95. One end of the groove 92 is an abutment portion 93 that connects to the embracing portion 91, and the other end is also an abutment portion 93. Because both sides of the groove 92 are abutment portions 93, it firmly supports the back surface of the D-type louver material (8D). In Example 2, the abutment portion 93 at the other end is a flat abutment surface. However, the abutment portion 93 may be one in which the end face of the groove wall of the groove 92 directly abuts against the back surface of the D-type louver material (8D), and is not flat.

[0087] Groove 92 is provided to accommodate a fastening member such as a bolt 923 for fixing mounting bracket 9 to base material 95. Therefore, groove 92 is deep enough to accommodate at least the head of bolt 923. A bottom 921 of the groove 92 abuts against the base material 95, and is provided with a bolt mounting hole 922. The width of the groove 92 is approximately the same diameter as the head of the bolt 923, and functions as a stopper for the bolt 923.

[0088] [Base material] In the under-elevated scaffolding 7, the base material 95 is fixed to the plate girder (under-elevated member) 51 or the like, and the louver material D-type (8D) which has become the louver panel body 2 is attached via the base material 95. The base material 95 is preferably made of high strength material such as H-shaped steel, in order to support the louver panel body 2 which is exposed to wind, etc.

[0089] [Medium aggregate] Figure 15(C) is a cross-sectional view of the section AA in Figure 15(A). The section AA is where the intermediate aggregate 86 (support member) lines multiple D-type louver materials (8D), and although it appears to be closed in the cross-sectional view, in reality, as shown in Figure 15(A), there are ventilation openings 826 (vertical gaps) on both sides of the D-type louver materials (8D) sandwiched between the intermediate aggregate 86 (support member). As described above, the D-shaped louver material (8D) is sandwiched between the holding portions 91 of a pair of mounting brackets 9 on both sides to form the louver panel body 2. The holding portions 91 and the D-shaped louver material (8D) are attached by driving tapping screws 912 into the holding portions 91. Therefore, when exposed to strong winds, a force is applied that tries to rotate the D-shaped louver material (8D) around the axis of the tapping screws 912. The D-shaped louver material (8D) attached to the mounting brackets 9 does not easily rotate because it is held by the holding portions 91. However, when exposed to strong winds, the D-shaped louver material (8D) may come off the holding portions 91 and rotate, or even if it does not come off, the tapping screws 912 may loosen. To prevent this, a strip-shaped plate-like, high-strength central frame 86 (support member) is attached. The central frame 86 (support member) is preferably attached to the center of the left and right width of the louver panel body 2. The central frame 86 (support member) connects the attached D-shaped louver materials (8D) vertically, and prevents the individual D-shaped louver materials (8D) from rotating. As mentioned above, the support member 3 is a component whose function is to unitize the louver material 4 into a louver panel body 2, and the intermediate frame 86 also functions to unitize the louver material 4, so it can also be called a support member 3. As described above, the support member 3 may be the mounting bracket 9 or the intermediate aggregate 86, and the shape, structure, mounting position, etc. are not important.

[0090] [Fixing of intermediate aggregate] The intermediate frame 86 (support member) is fixed to the hanging piece 81 of the D-shaped louver material (8D) with a screw 861. Space 83, surrounded by upper vertical surface 824, upper inclined surface 821, and hanging piece 81 shown in FIG. 14, functions as a space for accommodating the tip of screw 861 that is driven through hanging piece 81. Space 83 is located on the upper side of inclined surface 82 of louver material D-type (8D), and is a location that is less exposed to rain. Therefore, space 83 protects screws 861 and the screw holes into which screws 861 are driven from corrosion and other factors. This prevents core material 86 (support member), which is subjected to the load of a force that tries to rotate tapping screw 912 around its axis, from coming off louver material D-type (8D) due to corrosion of screws 861 and other factors.

[0091] [How to install the louver panel] Assembling a large number of D-type louver materials (8D) on-site reduces work efficiency. In particular, as shown in FIG. 3, the scaffolding 7 under the elevated structure is narrow, so assembling a large number of D-type louver materials (8D) on-site further reduces work efficiency. As shown in FIG. 15(A), pre-assembling the D-type louver materials (8D) and the mounting bracket 9 to form the louver panel body 2 can improve work efficiency. Furthermore, pre-inserting a bolt 923 through a bolt mounting hole 922 at the bottom 921 of the groove 92 of the mounting bracket 9 can further improve work efficiency on-site. The installation of the louver panel body 2 is completed simply by passing the bolt 923, which is pre-attached to the louver panel body 2, through the base material 95 and fastening it with a separately prepared nut 924. The mounting bracket 9 is not a special mounting member specifically designed for mounting the louver material type D (8D). The mounting bracket 9 can also be used to mount the louver panel body 2 of the louver material type A (4A) to the louver material type C (4C).

[0092] [Panel board] Figure 16 shows an example of an installation in which a D-type louver material (8D) is attached to a panel plate portion 87 to form a blocking portion 23. In the embodiment of Figure 15(A), a central frame 86 (support member) is used, and ventilation openings 826 (vertical gaps) are formed on both sides of the central frame 86 (support member). In the embodiment of Figure 16, a panel plate portion 87 (support member) with approximately the same width as the D-type louver material (8D) is used instead of the central frame 86 (support member). The panel plate portion 87 (support member) completely covers the back surface of the D-type louver material (8D), resulting in a blocking portion 23 with no openings anywhere. The embodiment of FIG. 16 is an example in which the panel plate portion 87 also functions as the support member 3, and is an example showing that the shape, structure, etc. of the support member 3 are not important. The louver panel body 2 using the panel plate portion 87 as the support member 3 can be attached to the base material 95 using the mounting bracket 9 described in Figure 15, or if the panel plate portion 87 is strong, the panel plate portion 87 and the base material 95 can be directly fastened together to attach them.

[0093] Example 3 [Louver material E type] Figure 17 is an explanatory diagram of the louver material type E (8E). Compared to the louver panel body 2 of the louver material type D (8D) in Figure 16, the first feature of the louver material type E (8E) is that the panel plate portion 87 integrally connects the inclined surface portions 82 spaced apart at a predetermined interval in the vertical direction on the inside, and is molded as a single unit. Therefore, in the louver material type E (8E), the panel plate portion 87 functions as the support member 3, and the louver material type E (8E) itself becomes the louver panel body 2. The uppermost end of the panel plate portion 87 is formed with only one upper horizontal piece portion 84 extending outward. Since the louver material type E (8E) only serves as the blocking portion 23, the parts other than the upper horizontal piece portion 84 at the upper end 8a of the louver material type E (8E) are omitted because they are not functionally necessary and do not make a strong impression in appearance. Furthermore, in the louver material E type (8E), tapping holes 823 are not provided on the rear surface of all the inclined surface portions 82. In this way, the louver material E type (8E) of Example 3 is one that retains the minimum necessary parts for function and appearance, and combined with the integral molding, it is possible to reduce costs.

[0094] For illustrative purposes, in Figure 17, the appearance of the type E louver (8E) is shown to resemble the type D louver (8D). However, the appearance of the type E louver (8E) may resemble any of the types A (4A) to C (4C). When viewed individually, the types A (4A) to C (4C) have different appearances. In particular, the type C louver (4C), which has a longer vertical strip 42, is clearly different from the type A louver (4A) and the type B louver (4B). However, when combined into a louver panel body 2, the shape of the inclined surface 41 creates a strong impression, and the vertical strip 42 is swallowed up by the inclined surface 41 of the louver 4 attached above, so it is perceived only as a difference in installation spacing, reducing its contribution to the appearance. In addition, the lower horizontal strip 43 is difficult to see, so its contribution to the appearance is low. Furthermore, the inside of the louver material 4 is darker than the outside, and even if there is a daylight opening 213, the difference between light and dark and the blocked portion 23 is not very noticeable. Therefore, it is difficult to distinguish between any type of louver material 4 except for the installation interval. Therefore, if a louver material type E (8E) that imitates one of the louver material types A (4A) to C (4C) is prepared and placed next to a louver panel body 2 consisting of louver material type A (4A) to C (4C), the positions of the inclined surface portions 41 will be aligned, and the appearance will be almost the same. In preparation for changing the mounting interval of the louver material 4, it is a preferable embodiment to prepare a louver material E type (8E) in which the mounting interval of the inclined surface portion 82 is changed.

[0095] [How to attach E-type louver material to the base material] FIG. 18 is an explanatory diagram of how the E-type louver material (8E) is attached to the base material 95. It can be attached in the same manner as in Example 2 using the mounting bracket 9. The difference is that the tapping holes 823 of the E-type louver material (8E) are not located on the inside of all of the inclined surface portions 82, but on every other one. This improves the efficiency of the installation work. The tapping hole 823 and the mounting bracket 9 are fastened with a tapping screw 912, and the louver material E type (8E) is fixed so as to embrace it from the side.

[0096] [Installation interval of E-type louver material] FIG. 19 is an explanatory diagram of the attachment interval (pitch) of the E-type louver material (8E). The figure shows two E-type louver materials (8E) attached to a base material 95, shown by the dotted line, one above the other. In Example 3, when the upper and lower E-type louver materials (8E) are attached so that the appearances of the numerous inclined surface portions 82 are evenly spaced, the positions of the lower end 871 of the panel plate portion of the upper E-type louver material (8E) and the upper horizontal piece portion 84 (upper end 8a) of the lower E-type louver material (8E) are set so that a thermal expansion allowance 89 (vertical gap) is created. The thermal expansion allowance 89 (vertical gap) is a gap to accommodate thermal expansion in the vertical direction of the E-type louver material (8E) when exposed to high summer temperatures, and prevents the lower end 871 of the panel plate portion of the upper E-type louver material (8E) from coming into contact with the upper horizontal piece portion 84 (upper end 8a) of the lower E-type louver material (8E). Of course, the upper and lower louver members E-type (8E) may be arranged with a larger distance between them to form ventilation openings 826 (vertical gaps).

[0097] At this time, the upper horizontal piece 84 limits the width of the thermal expansion allowance 89 (vertical gap) or ventilation opening 826 (vertical gap) formed between the lower end 871 of the panel plate portion of the upper louver material E type (8E) and the upper horizontal piece 84 of the lower louver material E type (8E) when viewed from the side.

[0098] Furthermore, although not shown in the figures, when louver material type E (8E) is made to imitate louver material type A (4A) to louver material type C (8C) as in Example 1, a functionally important lower horizontal piece portion 43 present in louver material type A (4A) to louver material type C (8C) may be provided at the lower end 8b of the lowest inclined surface portion 82 of louver material type E (8E). The lower horizontal piece 43 of the louver panel body 2 of the louver material type E (8E), which imitates the louver material type A (4A) to the louver material type C (8C), limits the width of the lower gap 827 formed between the lower horizontal piece 43 of the upper louver panel body 2 and the upper end 8a (upper horizontal piece 84) of the louver panel body 2 below it when viewed from the side. In the present invention, if necessary, a mode can be adopted in which a lower horizontal piece portion 43 is attached to the lower end 8b of the lowermost inclined surface portion 82 of the E-type louver material (8E).

[0099] [Uniformity of appearance] Figure 20 is an explanatory diagram of how to use louver material type D (8D) and louver material type E (8E), where Figure 20(A) is an example of using them on the top and bottom, and Figure 20(B) is an example of using them on the left and right. D-type louver materials (8D) are attached to the upper part of Figure 20(A), and the upper mounting brackets 9 support the multiple D-type louver materials (8D) from both sides, playing the role of support members 3. The attachment interval (pitch) of the D-type louver materials (8D) at the upper part is set at an interval that forms a ventilation and privacy section 22. On the other hand, louver material type E (8E) is attached to the bottom. The upper louver panel body 2 made of D-type louver material (8D) serves as a ventilation and privacy section 21, while the lower louver panel body 2 made of E-type louver material (8E) serves as a blocking section 23, and they are used differently. The louver panel body 2 made of the upper louver material D-type (8D) and the louver panel body 2 made of the lower louver material E-type (8E) have the same shape of the inclined surface portion 82, which makes a strong impression on the exterior. The louver material E-type (8E) omits some of the components that contribute little to the exterior (such as the upper horizontal piece portion 84 and tapping hole 823), but at a glance they are indistinguishable. Even when a louver panel body 2 made of louver material D-type (8D) and a louver panel body 2 made of louver material E-type (8E) are used side by side, a unified appearance can be achieved.

[0100] Figure 20(B) is an explanatory diagram showing how to use the louver panel body 2 on the left and right sides, with the left part being a louver panel body 2 made of D-type louver material (8D) and forming a ventilation / screening section 22. The right part is made up of two E-type louver material (8E) attached to a base material 95 with mounting brackets 9 and forming a blocking section 23. Once the louver panel bodies 2 on the right and left parts are attached to the base material 95 with the mounting brackets 9, the left and right parts look the same and are indistinguishable, even though the types of louver material 4 are different.

[0101] As described above, it is possible to meet the requirements for the location of the structure 1 where the louver panel body 2 is to be installed, for example, to make this a ventilation / screen section 22, or to make this a blocking section 23. The louver panel bodies 2 of the louver material type D (8D) and the louver material type E (8E) have very similar appearances, and can meet the requirements without compromising the unity of the design.

[0102] The specific configuration is not limited to these embodiments, and the present invention also includes design changes and the like within the scope of the present invention without departing from the gist of the present invention.

[0103] Furthermore, the above-described embodiments and various aspects can be combined by utilizing each other's techniques, as long as there are no particular contradictions or problems in the purpose, configuration, and the like. [Explanation of symbols]
