For this reason, the louvers are formed with joints that enable them to be joined to the brackets (see Patent Document 1 below, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2013-238064 A Summary of the Invention [Problem to be solved by the invention]

[0004] Lightweight metals such as aluminum are used for louvers, but in recent years, materials such as fireproof paper and medium density fiberboard (MDF) have begun to be used to further reduce weight and improve texture. When louvers are made of metal, it is easy to integrally form and process the joints that connect with brackets during manufacturing, but when they are made of fireproof paper or MDF, it is difficult to integrally form and process the joints that connect with brackets during manufacturing. Therefore, when installing louvers made of fireproof paper or MDF on structures such as beams and columns, it is necessary to prepare specially shaped brackets to connect with the louvers, which is not only costly but also time-consuming.

[0005] For these reasons, the present invention aims to provide a louver mounting holder that can be easily and cost-effectively installed on structural members such as ceiling beams and wall columns, even for louvers made of materials that are difficult to process into a single piece, such as non-flammable paper or MDF boards, as well as a louver unit and louver installation method that utilize this holder.

[0018] The embodiments of the louver mounting holder and the louver unit and the louver installation method using the same according to the present invention will be described with reference to the drawings. Note that the present invention is not limited to the following embodiments described with reference to the drawings, and various technical matters described in each embodiment can be appropriately combined, replaced, or omitted as necessary.

[0019] [First embodiment] A first embodiment of a louver installation holder, a louver unit using the same, and a louver installation method according to the present invention will be described with reference to Figs.

[0020] As shown in Figures 1 and 2, the base end (top end in Figures 1 and 2) of a U-shaped metal bracket 11 is fixed to a ceiling beam 1, which is a structural member, by a number of wood screws 12. On the other hand, a U-shaped metal fixture 13 is fitted into opening 101a at the end of louver 101, which is a square tube (e.g., 90 mm high, 30 mm wide, 2-3 m long) made of fireproof paper, so as to cover the opening.

[0021] The louvers 101 are oriented so that their longitudinal direction runs along the width direction of the bracket 11 (left-right direction in Figure 1), and the outer surface of the end side abuts the tip side of the bracket 11 (lower end side in Figures 1 and 2).

[0022] A number of screws 14, which are male threaded parts, are inserted into the tip end side of bracket 11 (the lower end side in Figs. 1 and 2), and these screws 14 pass through louver 101 and are screwed into mounting fixtures 13. As a result, louver 101 is sandwiched between the tip end side of bracket 11 and mounting fixture 13, and is fixedly supported on beam 1 via bracket 11. The end of louver 101, the peripheral edge of opening 101a, and mounting fixture 13 are covered with a cover plate 15 made of non-combustible paper. Cover plate 15 is attached to mounting fixture 13 with a number of screws 16.

[0023] Incidentally, reference numeral 17 denotes a screw for fixing the mounting fixture 13 to the louver 101. Here, each member will be described in more detail.

[0024] The bracket 11 is formed by combining a base end fitting 11A, which is an L-shaped base end member, and a tip end fitting 11B, which is a tip end member, to form a U-shape. The base end fitting 11A forms the base end side of the bracket 11, and is formed with a plurality of through holes 11Aa for mounting and fixing to the beam 1 with a plurality of wood screws 12. The tip end fitting 11B forms the tip side of the bracket 11, and is formed with a plurality of through holes 11Ba for mounting and fixing to the mounting fixture 13 via the louver 101 with a plurality of screws 14.

[0025] The base end fitting 11A and the tip end fitting 11B are arranged so as to overlap partially between the base end side and the tip end side of the bracket 11, and a plurality of communication holes 11Ab, 11Bb that communicate with each other are formed in the overlapping portion. Then, the base end fitting 11A and the tip end fitting 11B are fixed together by inserting a bolt 11C, which is a threaded part, into the communication holes 11Ab, 11Bb and screwing it into a nut 11D to tighten it.

[0026] The mounting fixture 13 has an end surface portion 13a that covers the opening 101a at the end of the louver 101, and edge surface portions 13b, 13c that protrude from the ends of one side (upper side in Figs. 1 and 2) and the other side (lower side in Figs. 1 and 2) of the end surface portion 13a and abut against the inner surface of the louver 101. The end surface portion 13a is formed with a screw hole 13aa that screws with the screw 16. The edge surface portion 13b is formed with a plurality of screw holes 13ba that communicate with the through hole 11Ba of the tip side metal fitting 11B of the bracket 11 and screws with the screw 14. The edge surface portion 13c is formed with a screw hole 13ca that screws with the screw 17.

[0027] Cover plate 15 has a plurality of through holes 15a formed therein for fastening with a plurality of screws 16 that screw into a plurality of screw holes 13aa in end surface 13a of mounting fixture 13. Cover plate 15 completely covers end surface 13a of mounting fixture 13, and also covers the peripheral edge of opening 101a of louver 101, giving opening 101a of louver 101 the same pattern as the outer surface of louver 101, thereby unifying the appearance of the entire louver 101.

[0028] 1 and 2, only one end of louver 101 in the longitudinal direction is shown, but the other end of louver 101 in the longitudinal direction has the same structure.

[0029] In this embodiment, the louver mounting holder 10 is made up of the bracket 11, wood screws 12, mounting fixture 13, screws 14, cover plate 15, screws 16, screws 17, etc., and the louver mounting holder 10, louver 101, etc. form the louver unit 100.

[0030] Next, a louver installation method using the louver installation holder 10 according to this embodiment will be described with reference to FIG.

[0031] First, the cover plate 15 is placed on the end surface 13a of the mounting fixture 13, and the screw 16 is inserted into the through hole 15a of the cover plate 15 and screwed into the screw hole 13aa of the end surface 13a of the mounting fixture 13, thereby attaching and mounting the cover plate 15 to the mounting fixture 13 (cover plate attachment process S11).

[0032] Next, edge surface portions 13b, 13c of mounting fixture 13 are inserted into opening 101a of louver 101 to fit mounting fixture 13, and screw 17 is passed through louver 101 and screwed into threaded hole 13ca of edge surface portion 13c and tightened, thereby attaching mounting fixture 13 to louver 101 (mounting fixture attachment process S12).

[0033] Next, the screw 14 is inserted into the through hole 11Ba of the tip side metal fitting 11B of the bracket 11, passed through the louver 101, and screwed into the threaded hole 13ba of the edge surface portion 13b of the mounting fixture 13, thereby attaching and mounting the tip side metal fitting 11B to the louver 101 via the mounting fixture 13 (tip side metal fitting (component) mounting process S13).

[0034] Then, the wood screw 12 is inserted into the through hole 11Aa of the base end metal fitting 11A of the bracket 11 and is screwed into the beam 1 and tightened, thereby attaching the base end metal fitting 11A to the beam 1 (base end metal fitting (member) attachment process S14).

[0035] Finally, the louver 101 is attached and held to the beam 1 via the bracket 11 by overlapping the base end fitting 11A of the bracket 11 with the tip end fitting 11B of the bracket 11 so that the communicating hole 11Ab and the tip end fitting 11Bb are connected to each other, inserting the bolt 11C, and screwing it into the nut 11D to fasten them together (installation process S15).

[0036] In this embodiment, even if the louver 101 is made of fire-resistant paper, for which it is difficult to form the joints as a single unit during manufacturing, the louver 101 can be attached and held to the beam 1 using only ordinary tools with the louver mounting holder 10, which is made up of only components with ordinary shapes.

[0037] Therefore, according to this embodiment, the louvers 101 can be easily installed on the beams 1 at low cost.

[0038] Furthermore, since the cover plate 15 completely covers the end face portion 13a of the mounting fixture 13 and also covers the peripheral edge of the opening 101a of the louver 101, the opening 101a of the louver 101 can be made to have the same pattern as the outer surface of the louver 101, thereby unifying the appearance of the entire louver 101.

[0039] Also, the base end metal fitting 11A of the bracket 11 is attached and fixed to the beam 1 with wood screws 12, while the tip end metal fitting 11B of the bracket 11 is attached and fixed to the mounting fixture 13 with screws 14 via the louver 101, and then the base end metal fitting 11A and the tip end metal fitting 11B of the bracket 11 are fastened with bolts 11C and nuts 11D, so that the louver 101 can be installed on the beam 1. Therefore, compared to when a bracket provided on the louver is directly fixed to the beam, or when a bracket provided on the beam is directly fixed to the louver, it is easier to install the louver on the beam, and workability can be further improved.

[0040] [Second embodiment] A second embodiment of a louver installation holder and a louver unit and a louver installation method using the same according to the present invention will be described with reference to Figures 4 to 6. However, for parts similar to those in the previously described embodiment, the same reference numerals as those used in the description of the previously described embodiment will be used, and descriptions that overlap with those in the previously described embodiment will be omitted.

[0041] 4 and 5, the base end side (upper end side in Figs. 4 and 5) of a metal bracket 21 having a substantially U-shape is fixed to the beam 1 by wood screws 12. The length of this bracket 21 in the width direction (left-right direction in Fig. 5) is longer (several times to more than ten times) than the length of the bracket 11 described in the above embodiment in the width direction (left-right direction in Fig. 1).

[0042] The louvers 101 are oriented so that their short sides (width direction) face along the width direction (left-right direction in Fig. 5) of the bracket 21, and are arranged in parallel along the width direction (left-right direction in Fig. 5) of the bracket 21, with the outer surfaces of the end sides abutting against the tip side (lower end side in Figs. 4 and 5) of the bracket 21. In other words, there are multiple louvers 101 arranged in parallel. Correspondingly, there are also multiple mounting fixtures 13, and each is fitted into the opening 101a of the louvers 101.

[0043] A number of screws 14 are inserted at predetermined intervals into the tip side of bracket 21 (the lower end side in Figs. 4 and 5) across the width (the left-right direction in Fig. 5), and these screws 14 pass through each louver 101 and screw into mounting fixture 13. Therefore, each louver 101 is sandwiched between the tip side of bracket 21 and mounting fixture 13, and is fixedly supported in parallel on beam 1 via bracket 21. Here, the members that differ from the embodiment described above will be described in more detail.

[0044] The bracket 21 is formed by combining a base end fitting 21A, which is an L-shaped base end member, and a tip end fitting 21B, which is a tip end member, to form a substantially B-shape. The base end fitting 21A constitutes the base end side of the bracket 21, and is formed with a through hole 21Aa for mounting and fixing to the beam 1 with a wood screw 12. The tip end fitting 21B constitutes the tip side of the bracket 21, and is formed with a plurality of through holes 21Ba at predetermined intervals in the width direction (left and right direction in FIG. 5) for mounting and fixing to the mounting fixture 13 via the louvers 101 with a plurality of screws 14 so that they are parallel to each other. In other words, there are a plurality of screws 14, and the louvers 101 arranged in parallel are fixed to the tip end fitting 21B.

[0045] The base end fitting 21A and the tip end fitting 21B are arranged so as to overlap partially between the base end side and the tip end side of the bracket 21, and communication holes 21Ab, 21Bb that communicate with each other are formed in the overlapping parts. Then, the base end fitting 21A and the tip end fitting 21B are fixed together by inserting the bolt 11C into the communication holes 21Ab, 21Bb and screwing it into the nut 11D to tighten it.

[0046] Note that Figure 4 shows only one longitudinal end side of louver 101, and Figure 5 shows only one widthwise end side of bracket 21, but the other longitudinal end side of louver 101 and the other widthwise end side of bracket 21 also have a similar structure.

[0047] In this embodiment, the louver mounting holder 20 is made up of the bracket 21, wood screws 12, mounting fixture 13, screws 14, cover plate 15, screws 16, screws 17, etc., and the louver mounting holder 20, louver 101, etc. form the louver unit 200.

[0048] In other words, in the above-mentioned embodiment, the louver unit 100 is constructed by applying a bracket 11 capable of holding one louver 101, but in this embodiment, the louver unit 200 is constructed by applying a bracket 21 capable of holding multiple louvers 101 in parallel.

[0049] Next, a construction method using the louver mounting holder 20 according to this embodiment will be described with reference to FIG.

[0050] First, as in the case of the above-described embodiment, the cover plate 15 is attached to the fixture 13 (cover plate attachment step S11), and the fixture 13 is attached to the louver 101 (fixture attachment step S12).

[0051] Next, the screw 14 is inserted into the through hole 21Ba of the tip side metal fitting 21B of the bracket 21, passes through the louver 101, and is screwed into the threaded hole 13ba of the edge surface portion 13b of the mounting fixture 13 for tightening. By performing this for each of the multiple louvers 101 arranged at predetermined intervals across the width direction of the bracket 21, the multiple parallel louvers 101 are fixed and attached to the tip side metal fitting 21B (tip side metal fitting (member) attachment process S23).

[0052] Then, the wood screw 12 is inserted into the through hole 21Aa of the base end metal fitting 21A of the bracket 21 and is screwed into the beam 1 and tightened, thereby fixing and attaching the base end metal fitting 21A to the beam 1 (base end metal fitting (member) attachment process S24).

[0053] Finally, the through holes 21Ab of the base end metal fitting 21A of the bracket 21 and the through holes 21Bb of the tip end metal fitting 21B of the bracket 21 are overlapped so as to communicate with each other, and the bolt 11C is inserted and fastened by screwing it into the nut 11D. As a result, the multiple louvers 101 are attached and held in parallel to the beam 1 via the bracket 21 (installation step S25).

[0054] That is, in the above-described embodiment, the louver unit 100 consisting of one louver 101 is installed on the beam 1, but in this embodiment, the louver unit 200 consisting of a plurality of louvers 101 arranged in parallel is installed on the beam 1. Therefore, it becomes possible to assemble the plurality of louvers 101 all at once in advance at a pre-factory or construction site, and then install them on the beam 1 of the ceiling.

[0055] Therefore, according to this embodiment, not only can the same effects as those of the previously described embodiments be obtained, but also multiple louvers 101 can be quickly installed, resulting in further cost reduction and improved work efficiency.

[0056] [Other embodiments] In the above-described embodiment, the cover plate mounting step S11 is performed before the mounting tool mounting step S12, but the present invention is not limited to this. In other embodiments, for example, the cover plate mounting step S11 can be performed between the mounting tool mounting step S12 and the tip-side metal fitting mounting steps S13, S23, between the tip-side metal fitting mounting steps S13, S23 and the base-side metal fitting mounting steps S14, S24, or after the base-side metal fitting mounting steps S14, S24. However, it is preferable to perform the cover plate mounting step S11 before the mounting tool mounting step S12 as in the above-described embodiment, since the construction of the louver 101 can be performed efficiently.

[0057] In the above-described embodiment, the base-end fitting attachment steps S14, S24 are performed after the tip-end fitting attachment steps S13, S23, but the present invention is not limited to this. In another embodiment, for example, the tip-end fitting attachment steps S13, S23 can be performed after the base-end fitting attachment steps S14, S24. However, it is preferable to perform the base-end fitting attachment steps S14, S24 after the tip-end fitting attachment steps S13, S23 as in the above-described embodiment, because this allows the construction of the louver 101 to be performed efficiently.

[0058] In the above-described embodiment, the brackets 11, 21 are applied in which the base end side metal fittings 11A, 21A and the tip end side metal fittings 11B, 21B are fixed with the bolts 11C and nuts 11D, but the present invention is not limited to this. As another embodiment, for example, it is also possible to apply a bracket made of a single member in which the base end side and the tip end side are integrated and fastening with a screw part is eliminated.

[0059] When using such a bracket made of a single member to install the louver 101 on the beam 1, a screw 14 is passed through the through hole at the tip side of the bracket and through the louver 101, and the screw 14 is screwed into the screw hole 13ba in the edge surface portion 13b of the mounting fixture 13 to attach the bracket to the louver 101 (bracket mounting process), and the base end side of the bracket is fixed to the beam 1 and the bracket is attached to the beam 1, thereby installing the louver 101 on the beam 1 (installation process).

[0060] This eliminates the need to insert the bolt 11C into the communicating holes 11Ab, 11Bb, 21Ab, 21Bb of the base end fittings 11A, 21A and the tip end fittings 11B, 21B and fasten them with the nut 11D, thereby reducing the number of work steps compared to the previously described embodiment.

[0061] However, in the above-described embodiment, the tip end fittings 11B, 21B to which the louver 101 is attached are fixed to the base end fittings 11A, 21A attached to the beam 1 with bolts 11C and nuts 11D, which is preferable as it makes the work easier than fixing a bracket to which the louver 101 is attached to the beam 1.

[0062] In the above embodiment, the louver 101 is installed on the beams 1 of the ceiling, but the present invention is not limited to this. Other embodiments can be applied to, for example, the interior structure of a building, including wall pillars, in the same manner as the above embodiment.

[0063] In the above embodiment, the louvers 101 are made of fireproof paper, but the present invention is not limited to this. As another embodiment, the present invention can be applied to louvers made of materials that are difficult to process as a single unit, such as medium density fiberboard (MDF), as well as louvers made of metal materials that are easy to process as a single unit, in the same manner as the above embodiment. In this case, it is preferable that the cover plate is made of the same material as the louvers.

[0064] In the above embodiment, the louver 101 is in a rectangular tube shape, but the present invention is not limited to this. As another embodiment, any louver having a tube shape, including a cylindrical shape, can be applied in the same manner as the above embodiment. In this case, the mounting fixture and the cover plate are shaped to match the shape of the opening at the end of the louver.

[0065] In the above embodiment, the case where the cover plate is applied has been described, but the present invention is not limited to this. As another embodiment, for example, in cases where the periphery of the opening at the end of the louver cannot be seen due to the installation situation, it is possible to omit the cover plate. [Industrial Applicability]

[0066] The louver mounting holder and the louver unit and louver installation method of the present invention can be easily and cost-effectively installed on structural members such as ceiling beams and wall columns, even for louvers made of materials that are difficult to process into a single piece, such as non-flammable paper or MDF boards, and can therefore be used with great advantage in a variety of industries, including the construction industry.
