Before describing the embodiments, the terms used in the present invention will be explained.
[Louver material]
Louvers are long, thin panels arranged in parallel with a space between them. They are used in a variety of places for the purposes of sun protection, ventilation, privacy, and blocking.
Louver material 4 refers to the unit members that make up the louvers. Generally, louvers are made up of slender blades that can be separated, and each slender blade is a constituent unit, so each blade is called a louver material 4. In the louver material type A (4A) in Fig. 5(A), the louver material type B (4B) in Fig. 5(B), the louver material type C (4C) in Fig. 6, the louver material type D (8D) in Fig. 14, and the louver material type E (8E) in Fig. 17, the slender blades are the unit members that make up the louvers. Each of these blades becomes a louver material 4.

[Support member]
1 is an explanatory diagram of the base material 95 and the support member 3, which is composed of a front view of the louver panel body 2, a cross-sectional view between A-A, B-B, C-C, and D-D in the front view, and an enlarged view of a rectangular area E. Louver material type A (4A) is used for explanation 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 a plurality of louver materials 4, which are unit members, to a support member 3 and unitizing them so that they can be attached directly to a base material 95. The front view and the cross-sectional view between A and A in Fig. 1 are drawings for explaining the role of the intermediate aggregate 86. Since a plurality of louver materials 4 are connected by the intermediate aggregate 86 to form the louver panel body 2, 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 central aggregate 86 is exemplified as the support member 3, the shape, structure, mounting 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 Figure 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 has the function of connecting each individual louver material D type (8D) to form a unit, as shown in Figure 15 (C), and therefore also serves as a support member 3.

FIG. 17 is an explanatory diagram of the E-type louver material (8E).
The louver material type E (8E) has a plurality of inclined surface portions 82 imitating the louver material 4, each of which is integrally connected to the inside of one panel plate portion 87. In the case of the louver material type E (8E), since the plurality of inclined surface portions 82 are integrally molded with one panel plate portion 87, the panel plate portion 87 functions as the support member 3. The louver material type E (8E) is also a louver panel body 2, since it is integrally molded with the panel plate portion 87.

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

[Horizontal piece]
The horizontal pieces are one of the features of the present invention. As shown in the enlarged view of the rectangular area E in Fig. 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. Each of the horizontal pieces affects the characteristics of the louver, such as ventilation, lighting, privacy, and obstruction.

[gap]
1 is an enlarged view of the rectangular area E added to the cross-sectional view taken along line B-B. The 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. The amount of air blowing from the outside to the inside changes when the mounting interval between the upper and lower louver materials 4 changes.
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, there 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, the inclined surface portion rear gap 413 is 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 wind blowing in changes.
There are other types of gaps, and the above examples are representative.
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.

The present invention also includes a louver material 4 that has only the upper horizontal piece 421, and a louver material 4 that has only the lower horizontal piece 43. When the louver material 4 is attached, the upper horizontal piece 421 or the lower horizontal piece 43 has a certain gap width. Of course, the present invention also includes an embodiment that has both the upper horizontal piece 421 and the lower horizontal piece 43.

These gaps affect characteristics 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, even if the width of the lower gap 221 is large, wind will not be able to blow in, resulting in a blocked portion 23.
Furthermore, if the width of the lower gap 221 is significantly restricted and there is no room for wind to blow in, it may become a blocked section 23 even if the width of the inclined surface portion rear gap 413 or the ventilation opening 222 (vertical gap) is large.

[Mounting part]
The louver material 4 must be attached to the base material 95. In the present invention, the means for attaching the louver material 4 to the base material 95 may vary. As shown in the enlarged view of the rectangular area E in FIG. 1, an attachment portion 45 is provided at the upper part of the back of the inclined surface portion, and a bag portion 451 is provided to accommodate a fastening material 46 such as a bolt so that the louver material 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 material 4 may be attached at an interval such that the upper horizontal piece portion 421 of the lower louver material 4 is swallowed up inside the inclined surface portion 41 of the upper louver material 4. When the lower louver material 4 in FIG. 2 is further raised and attached, the upper end 8a (upper horizontal piece portion 421) of the vertical piece portion 42 of the lower louver material 4 abuts against the upper inner side 412 of the inclined surface portion, which is the lower surface of the attachment portion 45, and the ventilation opening 222 (vertical gap) disappears, 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 attachment portion 45 is provided does not have to be the inclined surface portion upper inner side 412. Furthermore, when the mounting bracket 9 of Example 2 or Example 3 described below is used, the attachment portion 45 for fastening to the base material 95 is not required. Eliminating the attachment portion 45 expands the area that becomes the ventilation opening 222 (vertical gap).

[Length of horizontal piece]
The lengths of the lower horizontal piece 43 and the upper horizontal piece 421 can be appropriately determined depending on the desired characteristics such as ventilation, lighting, privacy, obstruction, etc. As an example, in the example of Figure 2, the length of the upper horizontal piece 421 is shorter than the width of the lower surface of the mounting part 45, so that the upper end 8a (upper horizontal piece 421) of the vertical piece 42 can abut against the lower surface 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 inclined surface portion back gap 413 will be restricted and disappear to become the 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 since the inclined surface portion back gap 413 becomes the blocked portion 23, ventilation will be lost.
The length of the lower side piece 43 can also be varied to affect different gap widths.

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.

[Overall scaffolding structure]
FIG. 3 is a schematic diagram of the first embodiment. 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 installed under the viaduct 5 is shown. Under the road surface material 52, an under-elevation member such as a plate girder 51 that supports the road surface material 52 is installed. Work is being carried out to install the scaffolding 7 between the legs 53, and a cross beam 75 of the scaffolding 7 is connected and supported by the under-elevation member such as the plate girder 51 via a cross beam support member 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 to form the structure 1.

Figure 4 shows a cross-sectional view of the elevated section 5 and an enlarged view of the frame a shown in the cross-sectional view. The scaffolding 7 can be attached to any elevated under-structure member, but it is preferable that the scaffolding 7 is 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 (elevated under-structure 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 Figure 4, an auxiliary member 774 can be attached to the side of the plate girder (elevated under-structure member) 51, and the cross beam support member 77 can be attached. The cross beam support member 77 can also be used as a base material 95 for attaching the louver panel body 2 by attaching the auxiliary member 774.

The louver material 4 shown in Example 1 has three types as shown in Figures 5 and 6. They 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 have the following common structure:

[Inclined surface]
All the 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 the first embodiment, 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 conspicuous in appearance.

[Mounting part]
The mounting portion 45 constituting a part of the inclined surface portion 41 is formed to have the same shape and the same size in all three types. The mounting portion 45 may be positioned as appropriate, but in Example 1, it is provided on the inside of the inclined surface portion 41. In addition, the louver material 4 can be attached by fastening work from the scaffolding 7 side.

The mounting portion 45 is provided with a bag portion 451. The bag portion 451 has a structure that allows the 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 bag 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 bag portion 451 contributes to improving the 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 the fastening material 46 is stored in the bag portion 451, so the fastening material 46 is not exposed on the front side of the louver material 4.

[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 type A (4A) to type C (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 type A (4A) and Figure 5(B) for louver material type B (4B).
The lower horizontal piece 43 acts as follows when multiple louver materials 4 are attached in the vertical direction of 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 louver material 4 below as seen from the side as shown in Fig. 5(B). When the upper horizontal piece 421 is provided and the lower horizontal piece 43 and the 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.

[Upper horizontal piece]
All three types have an upper horizontal piece 421 that extends outward from the upper end (upper end 422 of the vertical piece) of the louver material 4. Like the lower horizontal piece 43 described above, when multiple louver materials 4 are attached in the vertical direction of the base material 95 to form louvers, the upper horizontal piece 421 affects the width of the lower gap 221 that is formed between the upper louver material 4 in a side view and the upper horizontal piece 421 of the louver material 4 below it, and affects 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 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 limits 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.

[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 fits along the base material 95 when attached to the base material 95.
The lower horizontal piece 43 is a short member extending 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.

Also, the louver material type A (4A) has an upper horizontal piece 421 extending outward from the vertical piece upper end 422, which is the upper end of the louver material type A (4A). When a plurality of louver materials type A (4A) are attached in the vertical direction of the base material 95 to form the louver panel body 2, this affects the width of the lower gap 221 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 vertical piece upper end 422 (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 louver material A type (4A) located above and the louver material A type (4A) located below in side view. Even in an embodiment in which 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.

When a plurality of louver materials type A (4A) are attached in the vertical direction to the support member 3 to form the louver panel body 2, the upper horizontal piece 421 extending outward from the vertical piece upper end 422, which is the upper end of the louver material type A (4A), performs 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 generated on the upper and lower back sides. The vertical piece upper end 422 (upper horizontal piece 421) of the lower louver material type A (4A) constitutes part of the ventilation opening 222 (vertical gap) and limits the ventilation of the wind entering the inside through the ventilation opening 222 (vertical gap).
As described above, the lower horizontal piece 43 and the upper horizontal piece 421 restrict ventilation and mainly affect the privacy, ventilation and lighting properties.

When the louver material type A (4A) is installed with the lower vertical piece 42 of the louver material type A (4A) 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 widened, so that the louver material type A (4A) has high ventilation properties, allowing air to pass through from the inside of the inclined surface portion 41.
Details will be given later, but the louver material type A (4A) can be configured as a ventilation/lighting section 21 and a ventilation/privacy section 22 by adjusting the installation spacing.
At this time, the upper horizontal piece 421, in combination 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 the function as a screen.

[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 louver material type A (4A), the louver material type B (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 interval (pitch) is changed.

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 that the width of the lower gap 221 created between the lower horizontal piece 43 of louver material type B (4B) at the top and the vertical piece 42 of louver material type B at the bottom in side view becomes smaller, and ventilation from the lower gap 221 is significantly limited.
Since the louver material type B (4B) has a long lower horizontal piece 43, even if the louver material is installed spaced apart from one another so as not to overlap, almost no wind passes through to the inside of the inclined surface portion 41. The louver material type B (4B) is a type that places emphasis on relatively blocking properties, and can be used as a ventilation/lighting section 21 or a blocking section 23 by adjusting the installation interval.

[Louver material type C]
FIG. 6 is a side view of the louver material type C (4C), which differs from the louver material type A (4A) only in that the vertical piece portion 42 is longer.
The lower horizontal piece 43 of the louver material type C (4C) is short like the louver material type A (4A) (short enough to create a lower gap 221 below the louver material type C (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 .
Since the vertical piece 42 of the louver material Type C (4C) is longer than that of the louver material Type A (4A), the blocking effect is high even if the vertical installation interval is increased. As will be described in detail later, the louver material Type C is characterized by the fact that it can be used as any of the ventilation/lighting section 21, the ventilation/screening section 22, or the blocking section 23 by adjusting the vertical installation interval (pitch).

In particular, because the vertical piece 42 of the louver material C type (4C) is long, the position of the vertical piece upper end 422 (upper horizontal piece 421) is high, which significantly limits the width of the ventilation opening 222 (vertical gap) on the back side of the louver material C type (4C) that leads to the inside through the vertical piece upper end 422 (upper horizontal piece 421) of the louver material C type (4C) above and the louver material C type (4C) below in side view. In the louver material C type (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, and this is a type of louver material 4 that emphasizes concealment and obstruction.

(Other type variations)
The louver material 4 may be of various types in addition to 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 constituting the louver panel body 2 is the lower horizontal piece 43 or the upper horizontal piece 421, and the length of this can be varied to increase the variety. 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 with different degrees of ventilation and lighting properties.

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

Figure 7 shows an example of how to install louver material type A (4A). In the example in Figure 7, all of the louver materials type A (4A) in the figure are the same, and the vertical dimension is 60 mm.

FIG. 7(A) is a side view showing an example of mounting for comparison, FIG. 7(B) is a side view showing an example of mounting for increasing the mounting interval (pitch), and FIG. 7(C) is a side view showing an example of mounting for decreasing the mounting interval (pitch).
Note that Fig. 7(A) is a comparative reference diagram for explaining the influence of the installation interval (pitch). The installation interval (pitch) shown in Fig. 7(A) is not recommended as a standard, nor is it a preferred installation interval (pitch). The optimal installation interval (pitch) of the louver materials 4 varies depending on the surrounding environment of the place where the louver materials 4 are to be installed, the desired lighting, and other factors.

Please refer to FIG. 7(A) and an enlarged view of a part of it. This is the same for all types of louver panel bodies 2, but the side of the inclined surface portion 41 with respect to the base material 95 is the outside, and the side of the scaffolding 7, separated by the base material 95, is the inside. The lower horizontal piece portion 43 of the upper louver material type A (4A) and the vertical piece portion 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 upper and lower louver materials type A (4A) is set to 10 mm. Wind and light enter the inside of the scaffolding 7 from this daylight opening 213, but since the inside can be seen through the daylight opening 213, the inside cannot be concealed.

The vertical attachment spacing of 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) attached below, and is 70 mm in this attachment example.
Furthermore, the plurality of louver materials A type (4A) form a daylight opening 213 between the lower horizontal piece portion 43 of the upper louver material A type (4A) in side view and the vertical piece portion upper end 422 (upper horizontal piece portion 421) of the lower louver material A type (4A). Furthermore, a louver material A type (4A) ventilation opening 222 (vertical gap) leading to the inside of the scaffolding 7 is formed between the upper inside 412 of the inclined surface portion of the upper louver material A type (4A) and the vertical piece portion upper end 422 (upper horizontal piece portion 421) of the lower louver material A type (4A), and a part of this becomes the daylight opening 213.
This installation example is an installation example of louver material type A (4A) which serves as ventilation and lighting section 21.

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

Fig. 7(C) is an example of installation that prioritizes preventing rain from entering and objects from falling. The vertical installation interval of the louver material A type (4A) to the base material 95 is such that the lower horizontal piece 43 of the upper louver material A type (4A) and the vertical piece 42 of the lower louver material A type (4A) overlap when viewed from the front. In terms of overlap, it is negative at -10 mm, and the upper end 422 (upper horizontal piece 421) of the vertical piece of the lower louver material A type (4A) is swallowed up by the inside of the inclined surface part 41 of the upper louver material A type (4A). For this reason, there is no daylight opening 213 that allows the inside of the louver panel body 2 to be directly seen when viewed from the front, as in Fig. 7(B).
The daylight opening 213 has disappeared, but a lower gap 221 is created between the lower horizontal piece 43 of the louver material type A (4A) above in side view and the upper end 422 (upper horizontal piece 421) of the vertical piece of the louver material type A (4A) below. 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 louver material type A (4A) above in side view and the upper end 422 (upper horizontal piece 421) of the vertical piece of the louver material type A (4A) below.

Therefore, the wind entering from the lower gap 221 can enter 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 Fig. 7 (A), it is well ventilated, but it serves as a ventilation and concealment area where the inside cannot be seen from the front. The above has explained the installation interval (pitch) of the louver material type A (4A), but the installation interval (pitch) of the louver material type B (4B) and the louver material type C (4C) can also be changed as appropriate.

[Installation example with matching appearance]
Fig. 8 is an explanatory diagram of the 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 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 a lower horizontal piece 43 of a louver material 4 and a lower horizontal piece 43 of a louver material 4 attached below it.
8(A) shows a louver panel body 2 using louver material type A (4A), in which the louver material type A (4A) is attached at an attachment interval (pitch) of 70 mm to form a 10 mm daylight opening 213, forming a ventilation and daylighting section 21. In side view, a lower gap 221 is provided between the lower horizontal piece 43 of the upper louver material type A (4A) and the upper end 422 (upper horizontal piece 421) of the vertical piece of the louver material type A (4A) below. The ventilation opening 222 (vertical gap) on the back side of the louver material 4 is large and provides good ventilation.

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

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

FIG. 8(C) shows a louver panel body 2 using louver material C-type (4C), in which louver material C-type (4C) is attached at an attachment interval (pitch) of 60 mm. In the first embodiment, it is designed so that the upper horizontal piece 421 at the upper end 422 of the vertical piece of the lower louver material C-type (4C) just abuts on the inner side 412 of the upper inclined surface part where the attachment part 45 of the upper louver material C-type (4C) is located. Therefore, it is possible to attach it at an interval (pitch) of 60 mm just by attaching the vertical piece 42 of the lower louver material C-type (4C) by abutting it on the attachment part 45 of the upper louver material C-type (4C). The vertical dimension of the louver material C-type (4C) is 80 mm, but the vertical piece 42 of the lower louver material C-type (4C) is swallowed up by the inner side of the upper inclined surface part 41, and the overlap is -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, so that the ventilation opening 222 (vertical gap) on the back side of the louver material C type (4C) disappears, resulting in a blocked portion 23 that has no ventilation or lighting properties.
Compared to the louver material C type (4C) of Figure 8(C) with an installation interval (pitch) of 60 mm, the louver material A type (4A) of Figure 8(A) and the louver material B type (4B) of Figure 8(B) with an installation interval (pitch) of 70 mm, when placed side by side, it is clear that there is a difference in appearance, but it is not very noticeable. And when the louver panel body 2 of the louver material A type (4A) of Figure 8(A) is placed below and the louver panel body 2 of the louver material C type (4C) of Figure 8(C) is placed above, the difference in appearance becomes less noticeable.

In the louver panel body 2 in which the mounting intervals (pitch) of the louver material type A (4A) to the louver material type C (4C) are made the same, even if different types of louver panel bodies 2 are arranged on the left and right, the positions of the inclined surface parts 41 match in appearance and they become indistinguishable.
By simply adjusting the mounting interval (pitch), the same appearance can be achieved regardless of the type of louver material 4 used.

[Mounting interval (pitch) change]
FIG. 9 is an explanatory diagram of the change in the installation interval (pitch). By combining the type of louver material 4 to be adopted and the installation interval (pitch), the daylighting, ventilation, concealment, and obstruction properties can be appropriately adjusted. FIG. 9(A) shows an example in which a type A louver material (4A) is used, the installation interval is 80 mm, and a ventilation/daylighting section 21 is formed. The daylighting opening 213 is wider by 20 mm than in FIG. 8(A). Since the installation interval (pitch) is wider than in FIG. 8(A), more light enters the inside of the louver panel body 2. The installation examples in FIG. 8(A) and FIG. 9(A) are both examples in which a type A louver material (4A) is used as a ventilation/daylighting section 21, but in the example of FIG. 9(A), the installation interval is wider, and the daylighting and ventilation properties can be improved compared to the example of FIG. 8(A).

Figure 9(B) shows an example of an installation using louver material type C (4C) with an installation interval of 80 mm to form the ventilation and privacy section 22. As mentioned above, if the installation interval (pitch) of louver material types A (4A) to 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 and the intervals of the inclined surface sections 41 are aligned.

[Gap restriction by upper and lower horizontal pieces]
Various installation examples of louver material type A (4A) to type C (4C) have been described 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 described 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 makes it possible to 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 become narrower.
In addition, 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.

The present invention includes any one 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 does not substantially enter the inside of the inclined surface portion 41.
Furthermore, in the case of louver material type C (4C) which has a long vertical piece 42 with an upper horizontal piece 421, the ventilation opening 222 (vertical gap) is significantly restricted, and when the upper inner side 412 of the inclined surface portion of the louver material type C (4C) above and the upper horizontal piece 421 of the louver material type C (4C) below are installed with abutting spacing, essentially no wind will enter the inside through the ventilation opening 222 (vertical gap).
As shown in Figure 9 (A), when the upper and lower louver materials type A (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.

FIG. 10 is an explanatory diagram of changes in the mounting interval (pitch).
10(A) shows an example of installation in which louver material type A (4A) is used with an installation interval (pitch) of 60 mm, the same as the vertical dimension of the louver material 4, to form the ventilation and privacy section 22. The lower horizontal piece 43 of the upper louver material type A (4A) is attached to the base material 95 so as to overlap 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 as to be 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 louver material type A (4A) below and the upper inner side 412 of the inclined surface portion of the louver material type A (4A) above, thereby providing ventilation but creating a ventilation/concealment section 22 in which the inside cannot be seen from the front.

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

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 as to be swallowed up inside the inclined surface portion 41 of the upper louver material type B (4B), this will essentially result in a blocking portion 23.
The appearance of Figure 10(A), which uses louver material type A (4A), and Figure 10(B), which uses louver material type B (4B), is the same because the mounting intervals (pitch) are the same, so the spacing of the inclined surface portions 41 is uniform, and the appearance is the same despite the use of different types of louver materials 4.

[Versatility]
As described 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 that the size of the ventilation/lighting section 21 can be changed to prioritize ventilation or lighting. If ventilation is required but a screen function is also required, the ventilation/screening 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.

The present invention can provide a louver panel body 2 that can be used in a variety of situations and locations, such as in places where wind resistance and obstruction are important, such as bridges exposed to strong winds and rain, in places close to sidewalks where privacy is important, and in places 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.

Figure 11 is an explanatory diagram of versatility. Figure 11 (A) is an installation example of louver material type A (4A) that serves as a comparison standard, and is an example of 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.

Figure 11 (B) is a side view of the louver panel body 2 with the installation interval (pitch) increased by 80 mm. The same louver material Type A (4A) is used as the comparison standard. The installation interval (pitch) has been changed and widened from the comparison standard, so it is the same as the comparison standard in that it forms a ventilation and light section 21, but the installation example in Figure 11 (B) has improved the daylighting and ventilation properties of the louver panel body 2 by the amount that the installation interval (pitch) has been widened.

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 A type (4A) as the comparison standard is used. Since the installation interval (pitch) has been narrowed from the comparison standard, the louver panel body 2 becomes a ventilation/screening section 22.

Figure 11 (D) is a side view of the louver panel body 2 with a changed 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 mounting 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.

11(E) is a side view of a louver panel body 2 in which different mounting intervals (pitch) are used depending on the height. Both the upper and lower parts of the louver panel body 2 have in common that type A louver material (4A) is used, but the mounting interval (pitch) is wider at the upper part at 70 mm and narrower at the lower part at 50 mm. The mounting 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 swallowed up by the inclined surface portion 41 of the upper louver material type A (4A), resulting in a pitch of -10 mm.
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.

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 upper and lower parts of the louver panel body 2, but the upper part uses louver material type A (4A) and the lower part uses louver material type B (4B). Therefore, the upper part is a ventilation and lighting section 21, while the lower part is a ventilation and lighting section 21 that prioritizes wind protection.

[Using different shapes and spacing for the upper and lower louver panel bodies]
FIG. 12 is an explanatory diagram showing how the upper and lower parts of the louver panel body 2 are used separately.
In Fig. 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 in cases where priority is given to lighting so that the underside of the elevated structure 5 can be easily inspected.

In Fig. 12 (B), the installation interval (pitch) is slightly narrower, with the upper part being a ventilation/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 in cases where emphasis is placed on blocking, so that tools or pieces of concrete resulting from deterioration of the elevated structure 5 do not fall.

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

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

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/screening section 22 of louver material type A (4A).
In both Figures 13(A) and 13(B), louver materials 4 of different shapes 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.

The louver material type A (4A) can be installed at different installation intervals (pitch) to serve as a ventilation/lighting section 21 and a ventilation/screening section 22.
The louver material type B (4B) can be installed at different installation intervals (pitch) to create 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, the ventilation/screening section 22, and the 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 suited to the environment and the type of work to be done. Also, it is possible to create a structure 1 equipped with such a louver panel body 2.

[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 toward the top.

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

Furthermore, in Example 1 of the present invention, it has been shown that the degree of ventilation and lighting in the ventilation/lighting section 21 and the ventilation/concealment section 22 can be changed by changing the installation interval (pitch) of the louver material 4, and that by using different shapes, the appearance can be made the same.
Needless to say, four or more types of louver materials 4 may be prepared as long as they have a common inclined surface portion 41 .

Example 2
[Louver material type D]
The louver materials 4 from the louver material type A (4A) to the louver material type C (4C) of the first embodiment have both the upper horizontal piece portion 421 and the lower horizontal piece portion 43. FIG. 14 is a side view of the louver material type D (8D). As shown in the figure, the louver material type D (8D) of the second embodiment has an upper horizontal piece portion 84 at the upper end 8a of the vertical piece portion 88, but does not have a lower horizontal piece portion 43 at the lower end 8b of the inclined surface portion 82. When a plurality of louver materials type D (8D) are attached in the vertical direction to form a louver panel body 2, the width of the lower gap 827 formed between the inside of the inclined surface portion 82 of the louver material type D (8D) above in a side view and the upper horizontal piece portion 84, which is the upper end 8a of the louver material type D (8D) below it, is limited. If the upper horizontal piece portion 84 is made longer, the width of the lower gap 827 is limited and narrowed. In Fig. 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 a lower gap 827 between an upper louver material 4 and an underlying louver material 4 when viewed from the side.

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

The D-type louver material (8D) also has an inclined surface portion 82 that is inclined outward. The inclined surface portion 82 has an area that is configured in the following 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 the mounting bracket 9 described below.
As shown in FIG. 15, when the mounting bracket 9 is used to connect D-type louver materials (8D), which are unit components of the louvers, from the side to form a unit, the mounting bracket 9 also functions as a support member 3.
A vertical piece 88 extends upward and a hanging piece 81 extends downward, continuous with the upper inclined surface 821. An upper lateral piece 84 extending outward is provided on an 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 portion 81. This space 83 is where the tips of screws 861 for attaching the central aggregate 86 (support member) described later are placed.

The multiple D-type louver materials (8D) are attached in a vertical line along the direction shown by the dashed line in Fig. 14 with mounting brackets 9, which will be described in Fig. 15. In the mounting manner in Fig. 14, the D-type louver materials (8D) are attached at intervals such that the upper louver material D-type (8D) and the lower louver material D-type (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 provided between the upper louver material D-type (8D) and the lower louver material D-type (8D) when viewed from the side.

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 it is a ventilation and concealment section 22 that has ventilation but does not allow the inside to be seen from the outside.
In Example 2, the installation spacing (pitch) is set so that 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) exactly overlap when viewed from the front, and this is the installation spacing that maximizes the width of the ventilation opening 826 (vertical gap) in the form of a ventilation/privacy section 22.
When 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).

[Mounting bracket holding part]
Fig. 15 is an explanatory diagram of the attachment of D-type louver material (8D), Fig. 15(A) is an explanatory diagram of the louver panel body 2 and the mounting bracket 9, Fig. 15(B) is an enlarged view of the inside of the frame a in Fig. 15(A), and Fig. 15(C) is a cross-sectional view between A-A in Fig. 15(A). Since each D-type louver material (8D) is attached to the central frame 86 and the 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 called the 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 installed during on-site construction or may be installed at the factory.
The mounting bracket 9 can be fixed to an appropriate member of the scaffolding 7 under the elevated structure 5, but in the second embodiment, an H-shaped steel is attached to the girder (lower elevated structure member) 51 via an auxiliary member 774 as the base material 95 (see the enlarged view of the frame a in FIG. 4). The mounting bracket 9 shown by hatching in FIG. 15(B) is a long metal fitting so that multiple D-type louver materials (8D) can 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-type louver material (8D). The holding portion 91 is composed of three areas: a protruding portion 911, a projection wall portion 913, and an abutting portion 93. The projection wall portion 913 of the holding portion 91 covers the side of the D-type louver material (8D), and has a tapping screw 912 that is driven from the projection wall portion 913 toward the side of the D-type louver material (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).

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

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

When attaching the D-type louver material (8D) to the embracing portion 91, any suitable attachment method can be used. For example, a side wall (attachment portion) can be provided on the D-type louver material (8D), and the side wall and the projection wall portion 913 can be fastened together with a fastener.

[Mounting bracket contact part]
15(B) shows an enlarged view of the abutment portion 93 and the groove portion 92. The mounting bracket 9 has the abutment portion 93 connected to the projection 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 of them or both.

[Groove]
The mounting bracket 9 has a groove 92 adjacent to an abutment portion 93 that is connected 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 is connected to the holding portion 91, and the other end is also an abutment portion 93. Since both sides of the groove 92 are abutment portions 93, the abutment portion 93 at the other end is a planar abutment surface in Example 2. However, the abutment portion 93 may be one that is not planar, but in which the end face of the groove wall of the groove 92 directly abuts against the back surface of the louver material D-type (8D).

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

[Base material]
In the underpass scaffolding 7, the base material 95 is fixed to the plate girder (underpass member) 51 or the like, and the louver material D type (8D) which becomes 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.

[Medium aggregate]
Fig. 15(C) is a cross-sectional view taken along line A-A in Fig. 15(A). Line A-A is the area where the intermediate aggregate 86 (support member) backs the D-type louver members (8D), and although it appears blocked in the cross-sectional view, in reality, as shown in Fig. 15(A), both sides of the D-type louver members (8D) sandwiching the intermediate aggregate 86 (support member) are ventilation openings 826 (vertical gaps).
As described above, the louver D-type material (8D) is sandwiched between the holding parts 91 of a pair of mounting brackets 9 from both sides and attached to form the louver panel body 2. The holding parts 91 and the louver D-type material (8D) are attached by driving the tapping screw 912 from the holding part 91 side, so if it is exposed to strong winds, a force is applied that tries to rotate around the tapping screw 912. The louver D-type material (8D) attached to the mounting bracket 9 does not rotate easily because it is held by the holding part 91, but if it is exposed to strong winds, the louver D-type material (8D) may come off the holding part 91 and rotate, or the tapping screw 912 may loosen even if it does not come off. To prevent this, a belt-shaped plate material with high strength, a central aggregate 86 (support member), is attached. It is preferable to attach the central aggregate 86 (support member) to the middle of the left and right width direction of the louver panel body 2. The central frame 86 (support member) connects the multiple 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 member whose function is to unitize the louver materials 4 into the louver panel body 2, and the core material 86 also functions to unitize the louver materials 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 core material 86, and the shape, structure, mounting position, etc. are not important.

[Fixing of intermediate aggregate]
The central frame 86 (support member) is fixed to the hanging piece portion 81 of the D-type louver material (8D) with a screw 861.
The space 83 surrounded by the upper vertical surface 824, the upper inclined surface 821, and the hanging piece 81 shown in FIG. 14 functions as a place for accommodating the tip of the screw 861 that penetrates and is driven into the hanging piece 81. The space 83 is located on the upper side of the inclined surface portion 82 of the louver material D type (8D), and is a place that is not easily exposed to rain. Therefore, the space 83 protects the screw 861 and the screw hole into which the screw 861 is driven from corrosion, etc. The space 83 prevents the central aggregate 86 (support member), which is subjected to the load of the force that tries to rotate around the tapping screw 912, from coming off the louver material D type (8D) due to corrosion of the screw 861, etc.

[How to install the louver panel]
Assembling a large number of D-type louver materials (8D) on site is inefficient. 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 worsens work efficiency. As shown in FIG. 15(A), the work efficiency can be improved by assembling the D-type louver materials (8D) and the mounting bracket 9 in advance to form the louver panel body 2. In addition, the work efficiency on site can be further improved by inserting the bolt 923 in advance into the bolt mounting hole 922 at the bottom 921 of the groove portion 92 of the mounting bracket 9. The installation work of the louver panel body 2 is completed simply by passing the bolt 923 attached in advance to the louver panel body 2 through the base material 95 and fastening it with a nut 924 prepared separately.
The mounting bracket 9 is not a special mounting member specialized 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).

[Panel plate]
Fig. 16 shows an example of mounting the D-type louver material (8D) to the panel plate portion 87 to form the blocking portion 23. In the embodiment of Fig. 15(A), a central aggregate 86 (support member) is used, and ventilation openings 826 (vertical gaps) are formed on both sides of the central aggregate 86 (support member). In the embodiment of Fig. 16, a panel plate portion 87 (support member) having a width substantially the same as that of the D-type louver material (8D) is used instead of the central aggregate 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 a panel plate portion 87 also functions as a 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 may 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 may be directly fastened together to attach them.

Example 3
[Louver material type E]
Fig. 17 is an explanatory diagram of the louver material type E (8E). Compared with the louver panel body 2 of the louver material type D (8D) in Fig. 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 integrally molded. 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 a single upper horizontal piece portion 84 extending outward.
Since the E-type louver material (8E) is a type that only serves as a blocking portion 23, the upper end 8a of the E-type louver material (8E) has been omitted except for the upper horizontal piece portion 84, as this is not necessary for the function and does not give a strong impression in appearance.
In addition, in the louver material E type (8E), the tapping holes 823 are not provided on the back surface of any of the inclined surface portions 82.
In this way, the louver material type E (8E) of Example 3 has only the minimum necessary parts for function and appearance, and this, combined with the integral molding, enables cost reduction.

For the sake of explanation, in FIG. 17, the appearance of the louver material E type (8E) is made to resemble the louver material D type (8D), but the appearance of the louver material E type (8E) may resemble any of the louver materials A type (4A) to C type (4C). When the louver materials A type (4A) to C type (4C) are viewed individually, the impression of the appearance is different. In particular, the louver material C type (4C), which has a long vertical piece 42, is clearly different from the louver materials A type (4A) and B type (4B). However, when it is made into a louver panel body 2, the shape of the inclined surface portion 41 gives a strong impression, and the vertical piece portion 42 is swallowed up by the inclined surface portion 41 of the louver material 4 attached to the upper part, and is recognized only as a difference in the installation interval, and the contribution rate to the appearance is reduced. In addition, the lower horizontal piece portion 43 is difficult to see in the first place, so the contribution rate 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, even if a louver material type E (8E) imitating any one of the louver material types A (4A) to C (4C) is prepared and placed next to a louver panel body 2 consisting of the louver material types A (4A) to C (4C), the positions of the inclined surface portions 41 will be aligned, and the appearances will be almost the same.
In preparation for changing the installation interval of the louver material 4, it is a preferable embodiment to prepare a louver material type E (8E) in which the installation interval of the inclined surface portion 82 is changed.

[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 a 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 present 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.

[Installation interval of E-type louver material]
FIG. 19 is an explanatory diagram of the installation interval (pitch) of E-type louver material (8E).
The figure shows a state in which two louver materials E-type (8E) are attached to the base material 95 shown by the dashed line at the top and bottom. In Example 3, when the upper louver material E-type (8E) and the lower louver material E-type (8E) are attached so that the appearances of the numerous inclined surface portions 82 are arranged at equal intervals, the positions of the lower end 871 of the panel plate portion of the upper louver material E-type (8E) and the upper horizontal piece portion 84 (upper end 8a) of the lower louver material E-type (8E) are set so that a thermal expansion allowance 89 (vertical gap) is created. The thermal expansion allowance 89 (vertical gap) is a gap provided for the thermal expansion of the louver material E-type (8E) in the vertical direction when exposed to high temperatures in the summer, and prevents the lower end 871 of the panel plate portion of the upper louver material E-type (8E) from coming into contact with the upper horizontal piece portion 84 (upper end 8a) of the lower louver material E-type (8E). Of course, the upper and lower E-shaped louver materials (8E) may be arranged with a larger distance between them to form a ventilation opening 826 (vertical gap).

At this time, the upper horizontal piece 84 limits the width of the thermal expansion allowance 89 (vertical gap) or the ventilation opening 826 (vertical gap) that is 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) in side view.

Also, although not shown in the figure, 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 lower horizontal piece portion 43, which is present in louver material type A (4A) to louver material type C (8C), which is functionally important, 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 louver material type E (8E), which imitates louver material type A (4A) to 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).

[Uniformity of appearance]
FIG. 20 is an explanatory diagram of how to use the D-type louver material (8D) and the E-type louver material (8E), with FIG. 20(A) being an example of how to use them for the top and bottom, and FIG. 20(B) being an example of how to use them for the left and right.
20(A) is attached to the upper part, and the upper mounting bracket 9 supports the multiple D-type louver materials (8D) from both sides, playing the role of a support member 3. The mounting interval (pitch) of the D-type louver materials (8D) at the upper part is set to an interval that forms a ventilation/screening section 22.
On the other hand, an E-type louver material (8E) is attached to the lower part.
The upper louver panel body 2 made of D-type louver material (8D) serves as a ventilation/screening section 21, whereas 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 gives a strong impression to the appearance. In the louver material E type (8E), some of the members that contribute less to the appearance (upper horizontal piece portion 84, tapping hole 823, etc.) are omitted, but at a glance they are indistinguishable. Even if the louver panel body 2 made of the louver material D type (8D) and the louver panel body 2 made of the louver material E type (8E) are used side by side, a unified appearance can be achieved.

Figure 20 (B) is an explanatory diagram of how the louver panel body 2 is used on the left and right sides; the left part is a louver panel body 2 made of D-type louver material (8D) and serves as the ventilation and privacy section 22. The right part is made up of two E-type louver materials (8E) attached to a base material 95 with mounting brackets 9 and serves as the blocking section 23. Once the louver panel bodies 2 on the right and left parts are attached to the base material 95 with mounting brackets 9, the left and right parts look the same even though the types of louver materials 4 are different, and they become indistinguishable.

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, such as whether a certain area should be a ventilation/screening area 22 or a certain area should be a blocking area 23. The louver panel bodies 2 of louver material type D (8D) and louver material type E (8E) have very similar appearances, and can meet the requirements without compromising the uniformity of the design.

The specific configuration is not limited to these embodiments, and the present invention includes design changes that do not deviate from the gist of the present invention.

Furthermore, the above-mentioned embodiments and various aspects can be combined by reusing each other's technologies, so long as there are no particular contradictions or problems in their purpose and configuration, etc.
