The louvered ceiling structure of Patent Document 1 leaves an overall impression of the louver material and is poor in terms of design, and the mounting members for the louver material of Patent Document 2 use many complex and long members, which makes them expensive and uneconomical.

The present invention was made to solve the above problems, and its objective is to provide a ceiling louver mounting structure that has excellent design, contributes to the aesthetic appearance of the ceiling, is easy to install, and is economical.

In order to solve the above technical problems, the ceiling louver mounting structure of the present invention, as shown in Figure 1, comprises a long support member 6 placed horizontally on the ceiling of a building; clip members 8 attached to the support member 6 at predetermined intervals and having locking portions 42 formed at the bottom; long louver members 10; and long bar members 12 each having an edge 40 formed at the top. The bar members 12 are positioned and fixed to the top of the louver members 10, integrating them to form a connected louver member 14. The connected louver member 14 is positioned below the support member 6, and the locking portions 42 of the clip members 8 are locked to the edge 40 of the bar members 12 positioned at the top of the connected louver member 14. The top of the clip members 8 are attached to the support member 6, and the support member 6 supports the connected louver member 14. The louver member 10 is then attached to the ceiling member 4.

The ceiling louver mounting structure of the present invention comprises a hanging member 18 suspended from the ceiling frame of a building, a long support member 6 supported laterally on the hanging member 18, clip members 8 attached to the support member 6 at predetermined intervals and having locking portions 42 formed on both sides of the lower portion, a louver member 10 consisting of a long member with a rectangular or U-shaped cross section, and a bar member 12 consisting of a long member with a C-shaped cross section and having edge portions 40 formed on both sides of an opening 34, and the top of the louver member 10 The bar material 12 is placed and fixed to the ceiling portion 4 with its opening 34 facing upward, and these are integrated to form the connected louver material 14. The connected louver material 14 is then placed below the receiving material 6, and both locking portions 42 of the clip member 8 are respectively locked to the edge portions 40 of the bar material 12 at the top of the connected louver material 14. At the same time, the top of the clip member 8 is attached to the receiving material 6, and the receiving material 6 supports the connected louver material 14. The louver material 10 is then attached to the ceiling portion 4.

The ceiling louver mounting structure of the present invention uses a first clip member 8a as the clip member 8, which has two plate-shaped members 46, each with a hole 50 at the top of the plate-shaped members 46, a holding portion 52 formed in the center capable of holding the receiving member 6, and the left and right lower end portions each with the locking portions 42a (42) that protrude outward. Both locking portions 42a of the first clip member 8a are respectively locked to the edge portions 40 of the bar member 12 above the connecting louver member 14. The plate-shaped members 46 are then arranged facing each other, and the receiving member 6 is sandwiched between the holding portions 52 of the plate-shaped members 46. In this state, fasteners 54 are attached to the holes 50 to hold both plate-shaped members 46 to the receiving member 6, and the connecting louver member 14 is supported on the receiving member 6 using the first clip member 8a.

The ceiling louver mounting structure of the present invention uses a second clip member 8b as the clip member 8. The clip member 8 has a hanging piece 56 bent laterally at the top and has locking portions 42b (42) protruding outward at the left and right sides of the bottom end. Both locking portions 42b of the second clip member 8b are respectively locked to the edge portion 40 of the bar material 12 above the connecting louver material 14. 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.

The ceiling louver mounting structure of the present invention is configured such that, when the connecting louver materials 14 are sequentially mounted side by side on the receiving material 6 using the first clip member 8a, the connecting louver material 14 to be mounted last is mounted using the second clip member 8b, shifting the connecting louver material 14 to a position to the right or left from the designated, regular mounting location 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 in the regular position.

The ceiling louver mounting structure of the present invention is configured such that, when the connecting louver materials 14 are sequentially attached to the receiving material 6 in a line using the second clip members 8b, the orientation of the hooking piece 56 of the second clip member 8b relative to the receiving material 6 for the connecting louver material 14 attached later is reversed to the orientation of the hooking piece 56 of the second clip member 8b used to attach the previous connecting louver material 14, and the connecting louver material 14 is hooked onto the receiving material 6, and the connecting louver material 14 is supported in this state.

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 .

The ceiling louver mounting structure of the present invention employs a configuration in which 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 member placed above the connecting louver material, 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. Therefore, by placing the bar member above the louver material, the louver material stands out, enhancing the design and contributing to the aesthetic appearance of the ceiling. It also provides simple installation and excellent construction efficiency, making it economical.

In the ceiling louver mounting structure of the present invention, a bar material is placed and fixed above the louver material with its opening facing upward, forming 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 upper part of the clip member is also attached to the support material, and the support material supports the combined louver material. This configuration results in enhanced design, contributing to the aesthetic appeal of the ceiling, and also provides the effects of simple installation and excellent cost-effectiveness.

In the ceiling louver mounting structure of the present invention, both locking portions of the first clip member are respectively locked onto the edges of the upper bar material of the connecting louver material. At the same time, the plate-shaped materials are arranged facing each other, and a support material is sandwiched between the holding portions of these plate-shaped materials. Fasteners are then attached to the holes to hold both plate-shaped materials to the support material, and the connecting louver material is supported on the support material using the first clip member. This configuration ensures that the connecting louver material is firmly attached using the first clip member, and also provides the advantages of easy installation and superior workability.

The connecting structure of the present invention has two engaging portions of the second clip member that are respectively engaged with the edges of the upper bar material of the connecting louver material, and the hanging pieces are bent and hung on the receiving material. The connecting louver material is supported on the receiving material using the second clip member, which has the effect of simplifying installation of the connecting louver material using the second clip member and providing excellent workability.

With the connection structure of the present invention, when connecting louver materials are attached sequentially to a support member using the first clip member, the last connecting louver material to be attached is attached by using the second clip member described in claim 4 to shift the connecting louver material to a position to the right or left from the designated, regular attachment point on the support member. After attachment, the connecting louver material is slid along the support member together with the second clip member to the regular position and supported in the regular position. This allows for smooth, uninterrupted attachment of the connecting louver materials throughout, contributing to ease of installation.

With the connection structure of the present invention, when connecting louver materials are attached sequentially to a receiving material using second clip members, the orientation of the hooking piece of the second clip member relative to the receiving material for the connecting louver material attached later is reversed to the orientation of the hooking piece of the second clip member used to attach the connecting louver material first, and the connecting louver material is then hooked onto the receiving material in this state. This configuration maintains a balanced strength when connecting the connecting louver materials using the second clip members, resulting in good stability.

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 of the present invention.
This ceiling louver mounting structure is used by being attached to the ceiling of a building made of steel, reinforced concrete, wood, or the like.

This ceiling louver mounting structure primarily comprises a support member 6 placed on the ceiling section 4, a clip member 8, a long louver member 10 (slat), and a bar member 12. In this example, the bar member 12 is attached to the top of the louver member 10, and these are integrated into a combined louver member 14.

As shown in Figure 2, the support member 6 is a long, U-shaped steel member consisting of a base plate 15, upper and lower horizontal plates 17, and an opening 16 formed by these horizontal plates 17. The support member 6 is positioned horizontally with the opening 16 facing horizontally, supported by the receiving portion 21 of a hanger 20 attached to a hanging member 18 suspended from the ceiling frame.

As shown in Figure 3, the louver material 10 is a long piece of 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 resin materials 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).

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 cover 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, thereby closing off the end of the louver material 10. The material, surface coating, etc. of the cover member 30 are the same as those of the louver material 10.

As shown in Figures 4(a) and (b), the bar material 12 is a long material with a C-shaped cross section and 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.

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 fasteners 41 such as screws are used to secure the lower plate portion 36 of the bar material 10 to the upper surface portion 22 of the louver material 10. 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 the 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.

By using the combined louver material 14, the louver material 10 is attached to the ceiling portion 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.

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.

The first clip member 8a shown in Figure 1(a) has two plate-shaped members 46, 46, each with a fixing piece 48 formed on the top of the plate-shaped members 46 and a hole 50 in the center. Also, a holding portion 52 capable of holding the receiving member 6 is formed in the center, and locking portions 42a (42) are provided on the left and right sides of the lower end, each protruding outward.

The first clip members 8a have their locking portions 42a locked onto the edge portions 40 of the bar members 12 above the connecting louver members 14, while the plate members 46 are positioned facing each other. The support member 6 is then sandwiched between the holding portions 52 of the plate members 46, and fasteners 54, such as bolts and nuts, are attached to the holes 50 to fasten both plate members 46 to the support member 6, supporting the connecting louver members 14 together with the bar members 12.

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 its lower end.
The second clip member 8b has both locking portions 42b respectively locked to the edge portions 40 of the bar material 12 above 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.

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.

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) the receiving member 6.
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.

As shown in FIG. 6, first, the 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.

First, the connecting louver material 14 is placed below the receiving material 6, and both locking portions 42a of one of the plate-shaped materials 46 of the first clip member 8a are inserted into the opening 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.

Then, the plate-shaped members 46 of the first clip member 8a are placed facing each other, with the receiving member 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 member 6, allowing them to abut. The shanks of bolts serving as fasteners 54 are then 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 member 6. This allows the connecting louver member 14 to be supported on the receiving member 6 while engaged with the first clip member 8a.

It is also possible to first loosely attach the fixing piece 48 of the first clip member 8a to the receiving material 6 using a 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 and fix the fastener 54 of the fixing piece 48.
The connecting louver material 14 is usually fixed to the receiving material 6 at two locations, one on the left and one on the right, using the first clip members 8a. Therefore, the other locations of the connecting louver material 14 are similarly supported by the receiving material 6. In this way, the connecting louver materials 14 are attached to the receiving material 6 one by one.

Next, the installation using the second clip member 8b will be described as shown in Figure 7. In this case, too, 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 interior through the opening 34 of the bar material 12 fixed to the connecting louver material 14, and both locking portions 42b are respectively locked to both edge portions 40 of the bar material 12.

Then, the hanging piece 56 of the second clip member 8b is placed on top of the receiving material 6, and the receiving surface 58 of the second clip member 8b is placed to hold the side of the receiving material 6. The hanging piece 56 of the second clip member 8b is then bent approximately 90 degrees to hang 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.

It is also possible to first loosely attach the hooking piece 56 of the second clip member 8b to the receiving material 6, then hook the locking portions 42b onto the edges 40 of the bar material 12 of the connecting louver material 14, and then firmly hook and attach the hooking piece 56 to the receiving material 6. Other parts of the connecting louver material 14 can be supported by the receiving material 6 in the same manner.

The connecting louver materials 14 are attached sequentially in this manner. 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 will be attached so that it faces from the opening 16 side of the receiving material 6 toward the base plate 15.

The second clip member 8b is designed to attach the hooking piece 56 to the receiving material 6 from one direction, which results in an uneven attachment strength to the receiving material 6. Therefore, to balance this strength and ensure an overall stable attachment, the second clip members 8b are attached by alternating between different orientations.

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.

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

Therefore, 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 hooked onto the receiving member 6 to attach the connecting louver material 14.

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.

Therefore, a method is adopted in which the second clip member 8b is attached by shifting it toward the attachment position of the left-side connecting louver material 14, and then the second clip member 8b is slid together with the connecting louver material 14 to the correct position (right side).This makes it possible to easily attach the connecting louver material 14 to 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.

When installing louvers on a ceiling, by placing louver material 10 in the form of connected louver material 14 on the ceiling section 4, it is possible to improve and enhance the design and aesthetic aesthetics of the ceiling section.

The ceiling louver mounting structure according to the above embodiment therefore employs a configuration in which a bar material is attached to the top of the louver material, making the louver material more visible overall and enhancing the design. Furthermore, applying a wood-grain finish to the louver material contributes to the aesthetic appeal of the ceiling, and the work is simple, easy to install, and economical.
