[0011] In addition, the ceiling louver mounting structure of the present invention uses a second clip member 8b as the clip member 8, which has a hanging piece 56 bent sideways at the top and has the locking portions 42b (42) protruding outward at the left and right sides of the lower end, and both locking portions 42b of the second clip member 8b are respectively locked to the edge portion 40 of the bar material 12 at the top of the connecting louver material 14, and the hanging piece 56 is also bent and hooked onto the receiving material 6, and the connecting louver material 14 is supported on the receiving material 6 using the second clip member 8b.

[0012] The ceiling louver mounting structure of the present invention is configured such that, in the ceiling louver mounting structure, when the first clip member 8a is used to mount the connecting louver materials 14 in a row on the receiving material 6 in sequence, the second clip member 8b is used for the connecting louver material 14 to be mounted last, and the connecting louver material 14 is mounted by shifting it to a position to the right or left from the designated regular mounting point on the receiving material 6, and after mounting, the connecting louver material 14 is slid along the receiving material 6 together with the second clip member 8b to the regular position and supported at the regular position.

[0013] The ceiling louver mounting structure of the present invention is configured such that, in the ceiling louver mounting structure, when the second clip member 8b is used to sequentially mount the connecting louver materials 14 in a line on the receiving material 6, the direction in which the hanging piece 56 of the second clip member 8b is hung on the receiving material 6 for the connecting louver material 14 that is mounted later is reversed to the direction of the hanging piece 56 of the second clip member 8b that previously mounted the connecting louver material 14, and the connecting louver material 14 is hung on the receiving material 6, and the connecting louver material 14 is supported in this state.

[0014] The ceiling louver mounting structure of the present invention is configured such that the lower plate portion of the bar material 12 and the upper surface portion of the louver material 10 are fastened together from above the bar material 12 with fasteners 41, thereby fixing the two together and integrating them into the combined louver material 14. In addition, both ends of the louver material 10 are closed with cover members 30. [Effects of the Invention]

[0015] According to the ceiling louver mounting structure of the present invention, the connecting louver material is placed below the support material, the engaging portion of the clip member is engaged with the edge of the bar material placed on top of the connecting louver material, and the upper portion of the clip member is attached to the support material, the connecting louver material is supported by the support material, and the louver material is attached to the ceiling material.Therefore, by placing the bar material on top of the louver material, the louver material becomes more noticeable, enhancing the design and contributing to the aesthetic appearance of the ceiling, and also achieving the effects of simple work, excellent construction, and excellent economy.

[0016] According to the ceiling louver mounting structure of the present invention, a bar material is placed and fixed on top of the louver material with its opening facing upward, and these are integrated to form a combined louver material. The combined louver material is then placed below the support material, and both locking portions of the clip member are respectively locked to the edges of the bar material at the top of the combined louver material. The top of the clip member is also attached to the support material, so that the combined louver material is supported by the support material, and the louver material is attached to the ceiling.

[0022] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a ceiling louver mounting structure according to an embodiment. This ceiling louver mounting structure is used by attaching it to the ceiling of a building made of steel, reinforced concrete, wood, etc.

[0023] This ceiling louver mounting structure mainly comprises a support member 6 placed on the ceiling portion 4, clip members 8, long louver material 10 (slats), and bar material 12. In this example, bar material 12 is attached to the top of louver material 10, and a combined louver material 14 is used that integrates these.

[0024] As shown in Figure 2, the receiving member 6 is a long steel member with a U-shaped cross section, which is made up of a base plate 15, upper and lower horizontal plates 17, and an opening 16 formed by these horizontal plates 17. The receiving member 6 is placed horizontally with the opening 16 facing sideways, and is supported by a receiving portion 21 of a hanger 20 attached to a hanging member 18 suspended from the ceiling frame.

[0025] As shown in Figure 3, the louver material 10 is a long material with a rectangular or U-shaped cross section. This louver material 10 may have a square cross section, a rectangular cross section that is long vertically, or an open bottom. The louver material 10 has an upper surface 22, left and right side surfaces 24, and a lower surface 26 (which may also have an open shape). Here, low-cost square steel plates are used for the louver material 10, but other light metals such as aluminum or synthetic resins can also be used. The surface of the louver material 10 is painted in, for example, a wood-grain color (brown, dark brown, or light brown).

[0026] Furthermore, the louver material 10 is provided with a cover member 30, which closes both ends of the louver material 10 and also enhances the design. The lid member 30 has a rectangular cross section and is formed with a constricted insertion portion 32 in one direction. This insertion portion 32 is inserted into the interior of the louver material 10 from its end, closing off the end of the louver material 10. The material, surface coating, etc. of the lid member 30 are the same as those of the louver material 10.

[0027] 4(a) and 4(b), the bar material 12 is a long material with a C-shaped cross section having an opening 34 that is open at the top. The bar material 12 has a bottom plate portion 36, left and right side plate portions 38, and the tops of these side plate portions 38 each have edge portions 40, 40 that are bent inward and downward. The bar material 12 is made of lightweight steel, light metal such as aluminum, or synthetic resin material, etc.

[0028] Furthermore, here, the louver material 10 and the bar material 12 are used as an integrated unit. In this case, the lengths of the louver material 10 and the bar material 12 are approximately the same, and the bar material 12 is attached to the top of the louver material 10 to integrate them, forming a combined louver material 14. The bar material 12 is then placed on top of the louver material 10, and the lower plate portion 36 of the bar material 10 and the upper surface portion 22 of the louver material 10 are fixed using fasteners 41 such as screws. The fasteners 41 are attached at multiple locations at predetermined intervals. Here, one-touch screws (siltap screws) that do not require pilot holes are used as fasteners 41. The louver material 10 and the bar material 12 are cut in advance to a length required for arranging the louvers and to approximately the same length, and the two are integrated together to prepare a combined louver material 14.

[0029] By using the combined louver material 14, the louver material 10 is attached to the ceiling 4 using the bar material 12 at the top of the louver material 10. In other words, the bar material 12 of the combined louver material 14 is attached to the receiving material 6 using the clip member 8. Then, both locking portions 42, 42 of the clip member 8 are locked onto the edge portions 40, 40 of the bar material 12 related to the connecting louver material 14, and the upper portion of the clip member 8 is attached to the receiving material 6 to support the connecting louver material 14. The clip member 8 connects the receiving material 6 and the connecting louver material 14.

[0030] As shown in Figures 5(a) and (b), the clip member 8 has a bent portion formed on the upper side for holding the receiving material 6, and a locking portion 42 for locking the bar material 12 is provided on the lower side. Furthermore, here, two types of clip members 8 are used: a first clip member 8a and a second clip member 8b.

[0031] The first clip member 8a shown in Fig. 1(a) has two plate-shaped members 46, 46, each having a fixing piece 48 formed on the top of the plate-shaped members 46 and a hole 50 formed in the center thereof. Also, a holding portion 52 capable of holding the receiving member 6 is formed in the center, and engaging portions 42a (42) are provided on the left and right sides of the lower end portion, each of which protrudes outward.

[0032] The first clip members 8a have their locking portions 42a locked onto the edges 40 of the bar materials 12 above the connecting louver materials 14, and at the same time, the plate-like materials 46 are arranged facing each other. Then, the support material 6 is sandwiched between the holding portions 52 of the plate-like materials 46, and in this state, fasteners 54 such as bolts and nuts are attached to the holes 50 to fasten both plate-like materials 46 to the support material 6, thereby supporting the connecting louver materials 14 together with the bar materials 12.

[0033] The second clip member 8b shown in Fig. 2(b) has a hooking piece 56 formed on its upper part, bent at a right angle. The second clip member 8b also has a receiving surface 58 formed in the center, and has outwardly protruding locking portions 42b (42) on the left and right sides of the lower end. The second clip member 8b has both locking portions 42b locked to the edge portions 40 of the bar material 12 at the top of the connecting louver material 14. Then, the hooking piece 56 of the second clip member 8b is bent (approximately 90 degrees) to hook onto the receiving material 6, and the receiving material 6 supports the connecting louver material 14.

[0034] Next, the construction procedure for attaching the connecting louver material 14 to the ceiling portion 4 will be described. First, the hanging members 18 are hung from the ceiling frame. At the bottom of each hanging member 18, hangers 20 are attached by nuts 19 arranged at the top and bottom of the hanging members 18 so that they can move up and down. The hanging members 18 are attached at intervals that allow the support members 6 to be supported and at positions that allow the support members 6 to be arranged in parallel at predetermined intervals.

[0035] Then, the receiving member 6 is supported by the receiving portion 21 of the hanger 20, and the receiving member 6 is placed horizontally and sideways on the ceiling portion 4. The receiving member 6 is placed so that the connecting louver material 14 is attached in a direction intersecting (orthogonal to) it. Next, the connecting louver material 14 is attached. The connecting louver material 14 required to form the ceiling louvers may be prepared in advance at a factory, or the louver material 10 and bar material 12 may be cut and attached on-site to form a single piece. The connecting louver material 14 is attached to the support material 6 using clip members 8.

[0036] As shown in FIG. 6, first, attachment using the first clip member 8a will be described. The worker usually installs the connecting louver material 14 below the receiving material 6. For this reason, the worker installs the clip member 8 to the receiving material 6 above from below the receiving material 6 or the previously installed connecting louver material 14.

[0037] First, the connecting louver material 14 is placed below the receiving material 6, and then both locking portions 42a of one of the plate-shaped materials 46 of the first clip member 8a are inserted into the openings 34 of the bar material 12 fixed to the connecting louver material 14, and both locking portions 42a are locked onto both edge portions 40 of the bar material 12. The other plate-shaped material 46 of the first clip member 8a is locked in the same manner.

[0038] Then, the plate-shaped materials 46 of the first clip member 8a are placed facing each other, with the receiving material 6 sandwiched between their respective holding portions 52. At this time, the upper fixing pieces 48 of the first clip member 8a face each other above the receiving material 6 and are able to abut. Then, the shanks of bolts serving as fasteners 54 are inserted through the holes 50 of both fixing pieces 48, and the shanks are tightened from the other side with nuts, attaching the first clip member 8a to the receiving material 6. In this way, the connecting louver material 14 is supported on the receiving material 6 while being engaged with the first clip member 8a.

[0039] It is also possible to first loosely attach the fixing piece 48 of the first clip member 8a to the receiving material 6 using the fastener 54, and then in this state engage its engaging portion 42a with the edge portion 40 of the bar material 12 of the connecting louver material 14, and then later tighten the fastener 54 of the fixing piece 48 to secure it in place. The combined louver material 14 is usually fixed to the receiving material 6 at two locations, one on the left and one on the right side of the long material, using the first clip members 8a. Therefore, the other locations of the combined louver material 14 are similarly supported by the receiving material 6. In this way, the combined louver materials 14 are attached to the receiving material 6 one by one.

[0040] Next, the installation using the second clip member 8b will be described as shown in Figure 7. In this case as well, the worker installs the connecting louver material 14 below the receiving material 6. The connecting louver material 14 is placed below the receiving material 6, and both locking portions 42b of the second clip member 8b are inserted into the opening 34 of the bar material 12 fixed to the connecting louver material 14, and both locking portions 42b are locked to both edge portions 40 of the bar material 12, respectively.

[0041] Then, the hanging piece 56 of the second clip member 8b is placed on top of the receiving material 6, and with the receiving surface 58 of the second clip member 8b holding the side of the receiving material 6, the hanging piece 56 of the second clip member 8b is bent approximately 90 degrees to be hung on the receiving material 6. In this way, the connecting louver material 14 is supported on the receiving material 6 using the second clip member 8b.

[0042] It is also possible to first loosely attach the hanging pieces 56 of the second clip member 8b to the receiving material 6, and then in this state engage the locking portions 42b with the edge portions 40 of the bar material 12 of the connecting louver material 14, and then later firmly hook and attach the hanging pieces 56 to the receiving material 6. Other parts of the connecting louver material 14 are supported by the receiving material 6 in the same manner.

[0043] In this manner, the connecting louver materials 14 are attached sequentially. In this case, the attachment direction of the attachment piece 56 of the second clip member 8b to the receiving material 6 is alternately reversed. In other words, if the attachment piece 56 of the first attached second clip member 8b is attached so that it faces from the base plate 15 of the receiving material 6 toward the opening 16, the attachment piece 56 of the second clip member 8b attached next (closer to the worker) will have the attachment piece 56 facing in the opposite direction, and the attachment piece 56 will be positioned and attached from the opening 16 side of the receiving material 6 toward the base plate 15.

[0044] The second clip members 8b are configured to hook the hooking pieces 56 onto the receiving material 6 from one direction, which results in uneven attachment strength to the receiving material 6. Therefore, in order to balance this strength and ensure an overall stable attachment, the second clip members 8b are attached by alternately changing the orientation.

[0045] Now, when attaching the connecting louver materials 14 using the first clip member 8a, the connecting louver materials 14 are attached in order from one side of the receiving material 6, but there may be a wall portion 60 on the other side, and the hanger 20 of the hanging member 18 may be attached to the receiving material 6 near the wall portion 60. In this case, the connecting louver material 14 that is to be attached last is obstructed by other connecting louver materials 14, making it difficult for the worker to reach the top of the first clip member 8a and the receiving material 6, which causes problems during the work.

[0046] For example, as shown in Figure 1, the last connecting louver material 14 to be installed (second from the right) is obstructed by the connecting louver material 14 to its left, the hanger 20 on its right, and the connecting louver material 14 at the edge of the right wall portion 60. For this reason, if one were to attempt to install this (last) connecting louver material 14 as is, it would be difficult to fasten the bolts and nuts serving as fasteners 54 when attaching the first clip member 8a that connects this connecting louver material 14 to the receiving member 6.

[0047] Therefore, here, when attaching the last connecting louver material 14, the second clip member 8b is used instead of the first clip member 8a. Then, using this second clip member 8b, the connecting louver material 14 is first attached near the attachment position of the left connecting louver material 14 (almost in contact). In this position, the right hanger 20 and connecting louver material 14 do not get in the way, and the second clip member 8b can be hung on the receiving member 6 and the connecting louver material 14 can be attached.

[0048] In other words, the second clip member 8b has a hanging piece 56 formed on its upper part by being bent at a right angle, and after both engagement portions 42b at the lower end are engaged with the edge portions 40 of the bar material 12 of the connecting louver material 14, the hanging piece 56 is bent and hung on the receiving material 6. Therefore, after the second clip member 8b is attached to the receiving material 6, the upper hanging piece 56 remains hung on the receiving material 6 (not completely fixed), and therefore the hanging piece 56 can be moved along the receiving material 6 as is.

[0049] Therefore, a method is adopted in which the second clip member 8b is shifted toward the mounting position of the left-side connecting louver material 14 and then slid to the correct position (right side) together with the connecting louver material 14. This makes it possible to easily mount the connecting louver material 14 in the correct position. Furthermore, even if the holding portion 52 of the first clip member 8a is adapted to hold the receiving material 6 loosely (with some play), it will be able to slide along the receiving material 6, just like the second clip member 8b, and the same effect as described above will be obtained.

[0050] As a ceiling louver construction, by arranging the louver material 10 in the form of a combined louver material 14 on the ceiling portion 4, it is possible to improve and enhance the design and aesthetic appearance of the ceiling portion.

[0051] Therefore, according to the ceiling louver mounting structure of the above embodiment, by adopting a configuration in which a bar material is connected to the top of the louver material, the louver material becomes more noticeable overall, enhancing the design, and by applying a wood-grain paint to the louver material, it contributes to the aesthetic appearance of the ceiling, and also has the effect of being easy to work with, being excellent in construction, and being economical.
