Description

[Technical Field]

[0001] The present disclosure relates to a louver material mounting member and a ceiling structure. [Background technology]

[0002] Conventionally, for the sake of design, some ceiling structures use louver materials instead of ceiling board materials. Most louver materials are made of wood or light steel. Also, ceiling structures using lightweight glass wool boards as louver materials are known.

[0003] For example, Patent Document 1 discloses a building panel mounting system in which a building panel made of plate-shaped glass wool is mounted to a ceiling metal fitting extending horizontally on a ceiling. An insertion portion through which a mounting metal fitting is inserted is formed inside the building panel, and the mounting metal fitting is attached to the building panel. The building panel is mounted to a ceiling by connecting the mounting metal fitting attached to the building panel to the ceiling metal fitting with a connecting member. The connecting member includes a plate-shaped member extending horizontally, a ceiling metal fitting connecting portion that connects the ceiling metal fitting to the plate-shaped member, and a panel connecting portion that connects the mounting metal fitting to the plate-shaped member.

[0004] [Patent Document 1] Registered Utility Model No. 3237139 Summary of the Invention [Problem to be solved by the invention]

[0005] In ceiling structures using wooden and light steel louver materials, the louver materials have a certain weight, so they need to be firmly fixed to the ceiling substrate to prevent them from falling in the event of an earthquake, etc. This makes the structure (fixing members) for fixing the louver materials to the ceiling substrate complex, increasing costs and making the work of fixing the louver materials more complicated.

[0006] Furthermore, in a ceiling structure using building panels (louver materials) made of lightweight glass wool as described in Patent Document 1, mounting hardware must be provided on the building panels, which increases costs. Also, the mounting hardware for the building panels and the ceiling hardware must be connected with connecting members, which makes the work of fixing the louver materials more complicated.

[0007] Therefore, an object of the present disclosure is to provide a louver material mounting member and ceiling structure that has a simple structure and can easily and firmly mount a louver material to a ceiling. [Means for solving the problem]

[0008] In order to solve the above problems, a first aspect of the present invention is a louver material mounting member for mounting a louver material extending in a predetermined direction to a bar material, the louver material mounting member comprising: a fixing portion fixed to the bar material; and a pair of support plate portions extending downward from both sides of the fixing portion in a direction intersecting the predetermined direction, facing each other, defining a louver material insertion space into which the louver material can be inserted, and supporting the louver material inserted into the louver material insertion space, wherein at least one of the pair of support plate portions is positioned from above relative to the other support plate portion. It has a first region that becomes closer as it goes downward, and a second region that bends from the lower end of the first region and moves away from the other support plate portion as it goes downward, and the shortest distance between the bent portion between the first region and the second region of one support plate portion and the other support plate portion is shorter than the thickness of the louver material, the distance between the lower ends of the pair of support plate portions is longer than the thickness of the louver material, and the bent portion of one support plate portion clamps the louver material inserted into the louver material insertion space between itself and the other support plate portion.

[0009] A second aspect of the present invention is the louver material mounting member of the first aspect, wherein the other support plate portion is formed symmetrically to the one support plate portion.

[0010] A third aspect of the present invention is the louver material mounting member of the first aspect or the second aspect, wherein the pair of support plate portions each have a pin insertion hole through which a pin can be inserted.

[0011] A fourth aspect of the present invention is a ceiling structure comprising a louver material mounting member of the first aspect or the second aspect and the louver material, wherein the louver material has a base material made of glass wool board and a surface material covering the base material, is inserted into the louver material insertion space, and is sandwiched in an elastically deformed state between the bent portion of one support plate portion and the other support plate portion.

[0012] A fifth aspect of the present invention is the ceiling structure of the fourth aspect, wherein an upper surface of the louver material abuts against a lower surface of the fixing portion of the louver material mounting member.

[0013] A sixth aspect of the present invention is a ceiling structure comprising a louver material mounting member of the third aspect described above, the louver material, and a pin that passes through the pin insertion hole of the pair of support plate portions, wherein the louver material has a base material made of glass wool board and a surface material that covers the base material, and is inserted into the louver material insertion space and is clamped in an elastically deformed state between the bent portion of one support plate portion and the other support plate portion, and the pin passes through the louver material between the pair of support plate portions.

[0014] A seventh aspect of the present invention is the ceiling structure of the sixth aspect, wherein an upper surface of the louver material abuts against a lower surface of the fixing portion of the louver material mounting member. [Effects of the Invention]

[0015] According to the present disclosure, louver material can be attached to a ceiling easily and securely with a simple structure. [Brief explanation of the drawings]

[0019] As shown in Figure 1, a ceiling structure 1 according to one embodiment of the present invention is applied to the structure of a suspended ceiling that is placed below a ceiling structural material S and suspended from the ceiling structural material S. In this embodiment, the ceiling structure 1 includes a suspension bolt 2 hanging down from the ceiling structural material S, a joist support 3 attached to the lower end of the suspension bolt 2, a joist (bar material) 4 attached to the joist support 3, a louver material mounting member 10 attached to the joist 4, a louver material 5 supported by the louver material mounting member 10, and a spindle rivet (pin) 6.

[0020] The ceiling structural material S is, for example, a ceiling frame (ceiling slab). Note that the ceiling structural material S is not limited to a ceiling frame, but may be, for example, a purlin, a girder, a beam, or a horizontal member attached along or intersecting these.

[0021] The suspension bolts 2 are long bolts, and their upper ends are supported by the ceiling structural material S. In this embodiment, a plurality of suspension bolts 2 hang down from the ceiling structural material S.

[0022] The siding support 3 is a long member for supporting the siding members 4 and is attached to the lower ends of the hanging bolts 2 via hangers 7. In this embodiment, the siding support 3 extends in a direction (Y direction) intersecting the extension direction (Z direction) of the louver material 5 and is supported by hangers 7 attached to the lower ends of multiple hanging bolts 2. In other words, the siding support 3 is supported by multiple hanging bolts 2 via the hangers 7. Multiple siding support 3 are provided in parallel and spaced apart from each other in the Z direction. The material of the siding support 3 is not particularly limited, but examples include lightweight steel, light metals such as aluminum, and synthetic resin materials. Note that FIG. 1 illustrates one siding support 3, and other siding support 3 arranged at positions spaced apart from the siding support 3 in the Z direction are not illustrated. Furthermore, the cross-sectional shape of the siding support 3 is not limited to a rectangular shape and may be, for example, a C-shape.

[0023] The siding 4 is a long member for supporting the louver material 5 and is attached to the siding support 3 via connecting hardware 8. The siding 4 is positioned below the siding support 3, extends along the Z direction, and is supported by multiple siding supporters 3 via connecting hardware 8. Multiple sidings 4 are arranged parallel to each other and spaced apart in the Y direction. In this embodiment, the sidings 4 are arranged at equal intervals in the Y direction. The sidings 4 in this embodiment have a C-shaped cross section that opens upward. The material of the sidings 4 is not particularly limited, but examples include lightweight steel, light metals such as aluminum, and synthetic resin materials. While FIG. 1 illustrates four sidings 4, the number of sidings 4 is not limited to this and can be any desired number. Furthermore, the cross-sectional shape of the sidings 4 is not limited to a C-shaped cross section that opens upward, but may also be, for example, a rectangular cross section.

[0024] The louver material mounting member 10 is a member for supporting the louver material 5 and is fixed to the rafter 4. In this embodiment, the louver material mounting member 10 is arranged in contact with the underside of the rafter 4 and is fixed to the rafter 4. In this embodiment, multiple louver material mounting members 10 are provided for one rafter 4. These multiple louver material mounting members 10 are fixed to the rafter 4 while spaced apart from each other in the Z direction. Details of the louver material mounting member 10 will be described later.

[0025] As shown in Figure 2, the louver material 5 has a base material 5a made of glass wool board and a surface material 5b that covers the base material 5a. The base material 5a is the main component that constitutes the louver material 5 and is a solid glass wool board. The surface material 5b is the component that constitutes the surface of the louver material 5 and is provided with the design of the louver material 5. The design of the louver material 5 provided on the surface material 5b may be a simple, solid color design, or may be a wood grain design or the like.

[0026] The louver material 5 is formed in a plate shape that intersects with the Y direction and extends in the Z direction. The louver material 5 does not have any special components (metal fittings, etc.) for attaching the louver material 5 to the louver material mounting member 10. In this embodiment, the louver material 5 does not have any components other than the base material 5a and surface material 5b made of glass wool board.

[0027] The louver material 5 of this embodiment is formed with a rectangular cross section in which the length in the height direction (X direction) is longer than the length in the thickness direction (Y direction). The louver material 5 of this embodiment is disposed below the joist 4 and extends linearly in the Z direction along the joist 4 (see FIG. 1). The cross section of the louver material 5 is not limited to a rectangular shape, and any desired shape can be applied. For example, the cross section of the louver material 5 may be tapered downward or may be square. Furthermore, although the louver material 5 of this embodiment extends linearly, the present invention is not limited thereto, and the louver material 5 may extend curvedly in the Y direction, for example.

[0028] As shown in Figures 3 to 5, the louver mounting member 10 is a member for mounting a louver 5 extending in the Z direction (a predetermined direction) to a joist (bar material) 4. The material of the louver mounting member 10 is not particularly limited, but examples include lightweight steel, light metal such as aluminum, and synthetic resin material.

[0029] The louver material mounting member 10 has an upper fixed plate portion (fixing portion) 11 and a pair of support plate portions 12A, 12B extending downward from both ends of the fixed plate portion 11 in the Y direction, and is formed with a generally C-shaped cross section that opens downward. The louver material mounting member 10 defines a louver material insertion space 13 inside into which the louver material 5 can be inserted. In this embodiment, the fixed plate portion 11 and the pair of support plate portions 12A, 12B are integrally molded.

[0030] As shown in Figures 4(a) and 5, the fixing plate portion 11 of the louver mounting member 10 is a portion fixed to the rafter 4 and is formed in a plate shape that intersects in the vertical direction. In this embodiment, the fixing plate portion 11 is formed in a rectangular plate shape. The length W1 of the fixing plate portion 11 in the Y direction is formed to be greater than the thickness T (see Figure 2) of the louver 5 (W1>T). The fixing plate portion 11 defines the upper part of the louver insertion space 13. The fixing plate portion 11 has bolt insertion holes 14. The fixing plate portion 11 is fastened and fixed to the rafter 4 by bolts 15 inserted through the bolt insertion holes 14 and nuts 16 threaded onto the bolts 15 (see Figure 5). Note that the method of fixing the fixing plate portion 11 to the rafter 4 is not limited to fastening and fixing using the bolts 15 and nuts 16, and may be fixed, for example, by screwing or welding. In addition, in this embodiment, the portion of the louver material mounting member 10 that is fixed to the siding 4 is a plate-shaped fixing plate portion 11, but the portion that is fixed to the siding 4 is not limited to being plate-shaped, and any desired shape can be applied.

[0031] As shown in Figures 4(b) and 5, the pair of support plates 12A, 12B support the louver material 5 inserted into the louver material insertion space 13 from both sides in the Y direction, and extend downward from both sides of the fixed plate portion 11 in the Y direction and face each other. That is, the pair of support plates 12A, 12B are formed in the shape of plates that intersect with the Y direction. In this embodiment, the pair of support plates 12A, 12B bend and extend downward from both sides of the fixed plate portion 11 in the Y direction. The pair of support plates 12A, 12B define both sides of the louver material insertion space 13 in the Y direction. As a result, the louver material insertion space 13 is defined at the top by the fixed plate portion 11, at both sides in the Y direction by the pair of support plates 12A, 12B, and is open at the bottom and both sides in the Z direction.

[0032] In this embodiment, the pair of support plate portions 12A, 12B are formed symmetrically in the Y direction. That is, the other support plate portion 12B of the pair of support plate portions 12A, 12B is formed symmetrically with one support plate portion 12A. For this reason, hereinafter, only one support plate portion 12A (hereinafter sometimes simply referred to as "support plate portion 12A") will be described, and a description of the other support plate portion 12B (hereinafter sometimes simply referred to as "support plate portion 12B") will be omitted.

[0033] As shown in Figures 4(b) and 5, the support plate portion 12A has a first region 17 that becomes closer to the support plate portion 12B as it goes from top to bottom, and a second region 18 that bends from the lower end of the first region 17 and becomes farther away from the support plate portion 12B as it goes downward.

[0034] The first region 17 of the support plate 12A bends and extends downward from one edge of the fixed plate 11 in the Y direction. The angle between the fixed plate 11 and the first region 17 is set to be smaller than 90 degrees by a predetermined angle θ1. The predetermined angle θ1 (see FIG. 5) between an imaginary line VL1 that passes through one edge of the fixed plate 11 in the Y direction and is at a 90-degree angle with respect to the fixed plate 11 and the outer surface of the first region 17 in the Y direction is not particularly limited, but is preferably between 4 degrees and 10 degrees, and most preferably 6 degrees. If the predetermined angle θ1 is set to 4 degrees or less, it becomes difficult to firmly support the louver material 5. On the other hand, if the predetermined angle θ1 is set to 10 degrees or more, the shortest distance W2 (see FIG. 5) between the bent portion 19 of the support plate 12A and the other support plate 12B, which will be described later, may become shorter while maintaining the length of the fixed plate 11 in the Y direction. If the shortest distance W2 between the bent portion 19 of the support plate portion 12A and the other support plate portion 12B is too short, a strong force may be required to insert the louver material 5 into the louver material insertion space 13, making it difficult to insert the louver material 5 into the louver material insertion space 13 and potentially complicating the work. Furthermore, if the shortest distance W2 between the bent portion 19 of the support plate portion 12A and the other support plate portion 12B is too short, when the louver material 5 is formed by covering a base material 5a (e.g., a glass wool base material) with a surface material 5b (e.g., a wood-patterned sheet), wrinkles may easily form in the surface material 5b, potentially degrading the appearance of the louver material 5. Furthermore, if the shortest distance W2 between the bent portion 19 of the support plate portion 12A and the other support plate portion 12B is appropriately set and the predetermined angle θ1 is set to 10 degrees or more, the fixing plate portion 11 becomes longer in the Y direction, reducing the compactness of the louver material mounting member 10.

[0035] The second region 18 of the support plate portion 12A is bent at a bending portion 19 at the lower end of the first region 17 and extends downward and outward in the Y direction from the bending portion 19. In this embodiment, the second region 18 extends from the bending portion 19 to the lower end of the support plate portion 12A. The bending portion 19 extends linearly in the Z direction. The angle θ2 (see FIG. 5) between an imaginary line VL2 that passes through the bending portion 19 and is at an angle of 90 degrees with respect to the fixing plate portion 11 and the inner surface of the second region 18 in the Y direction is not particularly limited, but is preferably 12 degrees.

[0036] The shortest distance W2 between the bent portion 19 of the support plate portion 12A and the other support plate portion 12B is shorter than the thickness T of the louver material 5 (W2 < T). In the present embodiment, since the pair of support plate portions 12A and 12B are formed symmetrically with respect to the Y direction, the shortest distance W2 between the bent portion 19 of the support plate portion 12A and the other support plate portion 12B is the distance W2 between the bent portions 19 of the pair of support plate portions 12A and 12B as shown in FIG. 5.

[0037] The distance W3 between the lower ends of the pair of support plate portions 12A and the other support plate portion 12B is longer than the thickness T of the louver material 5 (W3 > T). In the present embodiment, the distance W3 between the lower ends of the pair of support plate portions 12A and 12B is shorter than the length W1 in the Y direction of the fixed plate portion 11 (W3 < W1).

[0038] The pair of support plate portions 12A and 12B of the present embodiment each have a pin insertion hole 20 through which the spindle bolt 6 can be inserted. In the present embodiment, three pin insertion holes 20 are provided in each of the pair of support plate portions 12A and 12B (six in total on both sides). The three pin insertion holes 20 of the pair of support plate portions 12A and 12B are arranged at intervals in the Z direction in the bent portion 19. The pin insertion holes 20 of one support plate portion 12A and the pin insertion holes 20 of the other support plate portion 12B are arranged at opposing positions. Note that the number and positions of the pin insertion holes 20 are not limited to the above, and any desired number can be provided at any desired position.

[0039] As shown in FIG. 6 , the spindle rivet (pin) 6 has a diameter large enough to pass through the pin insertion holes 20 of the pair of support plate portions 12A, 12B, and is formed longer than the distance between the pin insertion holes 20 of the pair of support plate portions 12A, 12B (the distance W2 between the bent portions 19 in this embodiment). The spindle rivet 6 of this embodiment has a plate 6a at one end. The plate 6a is larger than the pin insertion holes 20. The spindle rivet 6 is a member that reliably prevents the louver material 5 from falling off the louver material mounting member 10. The material of the spindle rivet 6 is not particularly limited, but examples include lightweight steel, light metals such as aluminum, and synthetic resins. Among these, a metal (e.g., aluminum) that can be easily bent by hand is preferable.

[0040] Next, a construction procedure for attaching the louver material 5 to the ceiling will be described.

[0041] When attaching the louver material 5 to the ceiling, first, the hanging bolts 2 are hung from the ceiling structural material S. A hanger 7 is attached to the bottom of each hanging bolt 2. The hanger 7 is adjustable in its vertical position relative to the hanging bolt 2. The hanging bolts 2 are spaced apart in the Y direction so that the joist support 3 can be supported, and at intervals in the Z direction so that the joist 4 can be supported.

[0042] Next, the siding support 3 is attached to the hanger 7 below the hanging bolt 2 while extending in the Y direction. Next, the siding support 4 is placed below the siding support 3 so as to straddle multiple siding supporters 3 while extending in the Z direction, and is attached to the multiple siding supporters 3 via connecting fittings 8.

[0043] Next, the multiple louver material mounting members 10 are fixed to the siding 4 while abutting against the siding 4 from below (see Figure 3). The multiple louver material mounting members 10 are preferably arranged so as to be located at the connecting portions between adjacent louver materials 5 in the Z direction and at the intermediate portions of each louver material 5.

[0044] Next, as shown in FIG. 6, the louver material 5 is inserted downward into the louver material insertion space 13 of the louver material mounting member 10. At this time, since the shortest distance W2 between the bent portion 19 of one support plate portion 12A and the other support plate portion 12B of the louver material mounting member 10 is shorter than the thickness T of the louver material 5 (W2 < T), the louver material 5 is inserted downward into the louver material insertion space 13 of the louver material mounting member 10 while being elastically deformed in the thickness direction. Then, the upper surface of the louver material 5 is brought into contact with the lower surface of the fixed plate portion 11 of the louver material mounting member 10 (see FIG. 6). As a result, the bent portion 19 of one support plate portion 12A sandwiches the louver material 5 inserted into the louver material insertion space 13 between it and the other support plate portion 12B (the bent portion 19 of the support plate portion 12B in this embodiment). On the other hand, the louver material 5 is sandwiched in an elastically deformed state between the bent portion 19 of one support plate portion 12A and the other support plate portion 12B.

[0045] In this embodiment, further, the spindle bolt 6 is inserted through the pin insertion holes 20 of the pair of support plate portions 12A and 12B of the louver material mounting member 10. At this time, in this embodiment, for the louver material mounting member 10 provided at the intermediate portion of the louver material 5 in the Z direction, the central pin insertion hole 20 in the Z direction among the three pin insertion holes 20 is used. On the other hand, for the louver material mounting member 10 provided at the connecting portion between the adjacent louver materials 5 in the Z direction, the pin insertion holes 20 on both sides in the Z direction among the three pin insertion holes 20 are used. That is, in order to fix the louver material 5 located on one side in the Z direction of the adjacent louver materials 5, the pin insertion hole 20 located on one side in the Z direction among the three pin insertion holes 20 is used, and in order to fix the louver material 5 located on the other side in the Z direction, the pin insertion hole 20 located on the other side in the Z direction among the three pin insertion holes 20 is used.

[0046] The spindle bolt 6 penetrates the louver material 5 between the pair of support plate portions 12A and 12B in the Y direction. The plate 6a of the spindle bolt 6 abuts against the outer surface in the Y direction of one support plate portion 12A. The tip side of the spindle bolt 6 protrudes outward in the Y direction from the pin insertion hole 20 of the other support plate portion 12B. Then, with the spindle washer 9 attached to the tip side of the spindle bolt 6, the tip side of the spindle bolt 6 is bent (see Fig. 6). Thereby, the louver material 5 can be attached to the ceiling. The spindle washer 9 is a plate-shaped washer having a pin insertion hole at the center. Note that the tip side of the spindle bolt 6 may be bent without attaching the spindle washer 9.

[0047] In the louver material attachment member 10 configured as described above and the ceiling structure 1 including the same, with the louver material attachment member 10 having a simple structure including the fixed plate portion 11 and the pair of support plate portions 12A and 12B, the louver material 5 can be attached to the ceiling.

[0048] Also, since the distance W3 between the lower ends of the pair of support plate portions 12A and 12B of the louver material attachment member 10 is longer than the thickness T of the louver material 5 (W3>T), when the louver material 5 is inserted into the louver material insertion space 13, the louver material 5 is unlikely to get caught on the lower ends of the pair of support plate portions 12A and 12B. For this reason, the louver material 5 can be easily inserted into the louver material insertion space 13.

[0049] Also, since the shortest distance W2 between the bent portion 19 of the support plate portion 12A of the louver material attachment member 10 and the other support plate portion 12B is shorter than the thickness T of the louver material 5 (W2<T), the louver material 5 is sandwiched in an elastically deformed state between the bent portion 19 of one support plate portion 12A and the other support plate portion 12B. For this reason, the louver material 5 can be firmly supported by the louver material attachment member 10, and it is difficult for the louver material 5 to fall from the louver material attachment member 10.

[0050] As described above, according to the present embodiment, the louver material 5 can be easily and firmly attached to the ceiling with a simple structure.

[0051] Furthermore, by forming the other support plate portion 12B of the louver material mounting member 10 symmetrically to one support plate portion 12A, the louver material 5 can be supported between the bent portions 19 of the pair of support plate portions 12A, 12B. This allows the louver material 5 to be supported by the louver material mounting member 10 more firmly.

[0052] Furthermore, by providing pin insertion holes 20 in the pair of support plate portions 12A, 12B of the louver material mounting member 10, the spindle studs 6 can be passed through the louver material 5 between the pair of support plate portions 12A, 12B in the Y direction. This makes it possible to reliably prevent the louver material 5 from falling off the louver material mounting member 10.

[0053] Furthermore, by abutting the upper surface of the louver material 5 against the lower surface of the fixing plate portion 11 of the louver material mounting member 10, it is possible to eliminate any gap above the louver material 5. This makes it possible to restrict movement of the louver material 5 relative to the louver material mounting member 10, allowing the louver material 5 to be attached more firmly to the ceiling.

[0054] Furthermore, by abutting the upper surface of the louver material 5 against the lower surface of the fixing plate portion 11 of the louver material mounting member 10, the positioning of the louver material 5 in the height direction can be easily performed.

[0055] Furthermore, the louver material 5 has a base material 5a made of a lightweight glass wool board, which reduces the risk of injury due to the louver material 5 falling during an earthquake or the like.

[0056] Furthermore, because the louver material 5 is lightweight and can be clamped between the louver material mounting members 10 and attached to the ceiling, there is no need to provide the louver material 5 with special components (metal fittings, etc.) or processing for attaching it to the louver material mounting member 10. This reduces costs and allows the louver material 5 to be easily attached to the ceiling.

[0057] Furthermore, the louver material 5 has the surface material 5b that covers the base material 5a, which can prevent the glass wool from scattering and improve the appearance of the louver material 5.

[0058] In this embodiment, the upper surface of the louver material 5 is abutted against the lower surface of the fixing plate portion 11 of the louver material mounting member 10, but this is not limited to this, and the upper surface of the louver material 5 may be spaced apart from the lower surface of the fixing plate portion 11.

[0059] Furthermore, in this embodiment, spindle stud 6 is used as an example of the pin that penetrates louver material 5, but the present invention is not limited to this and may be, for example, a split pin formed in a U-shape. In the case of a split pin formed in a U-shape, the split pin may be passed through louver material 5, and the tips of the bifurcated pin on the open side may be protruded outward in the Y direction from pin insertion hole 20 of the other support plate portion 12B, and then the tips of the bifurcated pin may be bent in directions that move them apart from each other.

[0060] Furthermore, in this embodiment, pins (spindle rivets 6) are provided to penetrate the louver material 5, but this is not limiting and pins may not be provided. Even in this case, the louver material 5 is sandwiched in an elastically deformed state between the bent portion 19 of one support plate portion 12A and the other support plate portion 12B, so the louver material 5 can be easily and firmly attached to the ceiling with a simple structure as described above. Also, in this case, it is not necessary to provide pin insertion holes 20 in the pair of support plate portions 12A, 12B of the louver material mounting member 10.

[0061] Furthermore, in this embodiment, the other support plate portion 12B of the louver material mounting member 10 is formed symmetrically to the one support plate portion 12A, but this is not limited to this. For example, the other support plate portion 12B may be bent at a 90-degree angle relative to the fixed plate portion 11 from the other edge in the Y direction of the fixed plate portion 11 and extend linearly to the lower tip, so that it is formed asymmetrically with the one support plate portion 12A. Even in this case, the louver material 5 is sandwiched in an elastically deformed state between the bent portion 19 of the one support plate portion 12A and the other support plate portion 12B, so that the louver material 5 can be easily and firmly attached to the ceiling with a simple structure as described above.

[0062] Furthermore, in this embodiment, the first region 17 of one support plate portion 12A of the louver material mounting member 10 is bent and extends downward from one end edge in the Y direction of the fixed plate portion 11, but this is not limited to this, and another region may be provided between one end edge in the Y direction of the fixed plate portion 11 and the first region 17. For example, another region may be provided that extends downward from one end edge in the Y direction of the fixed plate portion 11 at an angle of 90 degrees to the fixed plate portion 11, and the first region 17 may extend downward from the lower end of that other region.

[0063] Furthermore, in this embodiment, the second region 18 of one support plate portion 12A of the louver material mounting member 10 extends from the bent portion 19 to the lower end of the support plate portion 12A, but this is not limited to this. The second region 18 may be any region that bends from the lower end (bent portion 19) of the first region 17 and moves downward relative to the other support plate portion 12B. In other words, the second region 18 may be any region that forms the bent portion 19 that protrudes inward in the Y direction between itself and the first region 17.

[0064] In addition, in this embodiment, one first region 17 and one second region 18 of the louver material mounting member 10 is provided on one support plate portion 12A, thereby providing one bending portion 19 on one support plate portion 12A, but this is not limited to this. For example, multiple first regions 17 and multiple second regions 18 may be provided on one support plate portion 12A, thereby providing multiple bending portions 19 on one support plate portion 12A.

[0065] Although the present invention has been described above based on the above embodiment, the present invention is not limited to the content of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, operational techniques, etc. made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
