Description

[Technical Field]

[0001] The present invention relates to a ceiling structure with visually interesting lighting. [Background technology]

[0002] In recent years, the ceilings in offices in office buildings and stores in commercial buildings are often constructed with suspended ceilings called system ceilings. A system ceiling is a suspended ceiling made up of a combination of unit ceilings, with ceiling panels placed on top, making it easy to install lighting fixtures, air conditioning vents, and other equipment.

[0003] For example, the system ceiling in Patent Document 1 is configured by providing a rectangular opening in the ceiling panel of a building's ceiling and arranging lighting fixtures in a square shape in the rectangular opening. That is, a large number of suspension bolts are provided in the ceiling space, lattice-shaped bars are placed on the suspension bolts, and lighting fixtures configured in advance in a square shape are attached to the bars to form a lighting device for a system ceiling.

[0004] In this type of system ceiling, the ceiling panels and equipment such as lighting devices are arranged flush and linearly, giving the system a clean, smart appearance and also making it easy to maintain. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 5-242707 Summary of the Invention [Problem to be solved by the invention]

[0006] As mentioned above, conventional system ceilings equipped with lighting devices have fluorescent lights embedded in part of the ceiling surface. Although the flat surface makes for a good design, the fact that fluorescent lights are shining overhead gives it an old-fashioned impression. Even if the fluorescent lights were replaced with LEDs, there would not be much difference.

[0007] Therefore, an object of the present invention is to provide a ceiling structure that allows the installation of new lighting that takes advantage of a variety of light reflection and diffusion effects. [Means for solving the problem]

[0008] In order to solve the above problem, one aspect of the present invention provides a ceiling structure comprising an upper ceiling and a suspended ceiling suspended from the upper ceiling, the suspended ceiling being made of a light-transmitting metal mesh sheet.

[0009] In one embodiment, the upper ceiling is a ceiling slab, the suspended ceiling is suspended from the ceiling slab, and an attic space is formed between the ceiling slab and the suspended ceiling. Furthermore, a lighting fixture is provided in the attic space, and when the lighting fixture is turned on, its light is diffusely reflected by the metal mesh sheet and passes through it, illuminating the space below the suspended ceiling.

[0010] Furthermore, in one embodiment, the metal mesh sheet is formed by weaving extremely fine stainless steel wires.

[0011] Furthermore, in one embodiment, the stainless steel ultra-fine wire has a thickness of 0.01 mm to 0.1 mm and a mesh number of 80 mesh to 700 mesh. [Effects of the Invention]

[0012] The system ceiling according to the present invention can produce a variety of light reflection and diffusion effects, creating a fresh, luminous space. [Brief explanation of the drawings]

[0014] Hereinafter, an embodiment of the ceiling structure according to the present invention will be described with reference to the accompanying drawings. Figure 1 is a cross-sectional view of a system ceiling equipped with the ceiling structure according to the present invention. Here, an office room is shown, but it would also be effective to install the system ceiling according to the present invention in a showroom, store, etc.

[0015] That is, the space of the office room is surrounded by a ceiling slab 1, a floor slab 3, and walls 5. A suspended ceiling 9 is suspended from the ceiling slab 1 by suspension devices 7 such as suspension bolts. Various types of ceiling equipment are installed in the space (attic) S between the ceiling slab and the suspended ceiling, but only an air conditioning duct 11 is shown here as an example.

[0016] Other ceiling equipment includes circulation fans, sprinkler piping, ventilation piping, gas piping, electrical wiring, signal wiring, telephone wiring, television antenna wiring, routers, antennas, etc. In the present invention, a lighting fixture 13 is installed in this ceiling space S. This lighting fixture is preferably a general LED lighting fixture, but fluorescent lamps can also be used.

[0017] In the figure, the lighting fixture 13 is installed on the ceiling slab 1, but it may be placed anywhere within the ceiling space S. For example, it may be hung from the ceiling slab 1.

[0018] The suspended ceiling 9 consists of lattice-shaped ceiling frames suspended from the ceiling slab 1, and ceiling panels installed between the ceiling frames to close the openings of the lattice. However, some of the lattice openings have necessary equipment installed in place of ceiling panels, such as air conditioning outlets 15. The ceiling frames and ceiling panels form an attic space S below the ceiling slab.

[0019] Figure 2 is a perspective view of the ceiling frame material used here. As shown here, ceiling frame material 17 is made up of grid bars 17a, 17b, each made of steel or aluminum alloy, etc., with a roughly inverted T-shaped cross section, assembled in a cross-section. These grid bars 17a, 17b have webs 17w that stand upright along the longitudinal direction of the members and flanges 17f that protrude on both sides from the lower edges of webs 17w. Ceiling panels 19 are erected on top of these protruding flanges 17f (see Figure 3).

[0020] The grid-shaped opening O of the ceiling frame material 17 is square, with each side measuring 500 mm to 700 mm, for example 600 mm. The ceiling board 19 installed in the opening O is also square, like the grid, but is smaller than the grid by approximately the thickness of the web 17w of the ceiling frame material, so that it fits exactly into the opening O.

[0021] Fig. 4 shows a plan view of a ceiling panel 19 according to an embodiment of the present invention, and Fig. 5 shows a cross-sectional view of the ceiling panel 19 according to an embodiment of the present invention. This ceiling panel 19 is made of a narrow square frame 19f made of, for example, ABS resin, and a metal mesh sheet 19m attached so as to cover the entire opening of this frame 19f.

[0022] The metal mesh sheet 19m of the ceiling panel 19 is formed by weaving extremely fine stainless steel wires, and a suitable example is one that can be used as a screen mesh for screen printing. This metal mesh sheet 19m is made up of warp and weft threads, and examples of the wire thickness and mesh count (number of threads per inch) are 0.01 mm to 0.1 mm and 80 mesh to 700 mesh. For example, 0.03 mm x 100 mesh, 0.03 mm x 200 mesh, 0.05 mm x 80 mesh, 0.016 mm x 325 mesh, 0.019 mm x 500 mesh, etc. can be used.

[0023] Due to the thickness of the wire and the number of meshes, the metal mesh sheet 19m of the ceiling board 19 allows light to pass through, but the surface of the extremely fine wires with a stainless steel luster causes a variety of diffused reflections, resulting in a unique shine. Therefore, when light from the lighting fixtures 13 installed in the attic space passes through the metal mesh sheet 19m of the ceiling board 19, it creates optical effects such as halation and moire, adding a unique touch to the indoor space. [Industrial Applicability]

[0024] The ceiling structure of the present invention allows for the creation of an extraordinary space through new lighting that takes advantage of the diverse light reflection and diffusion effects, and makes it possible to install extremely effective lighting fixtures.

[0025] The above describes the system ceiling of the present invention based on an embodiment, but the present invention is not limited to this, and modifications may be made within the scope of the spirit of the present invention, and if possible, the technologies described in each embodiment may be combined, or publicly known technologies may be combined, etc.

[0026] For example, in the above embodiment, the metal mesh sheet 19m is tautly attached to the frame 19f of the ceiling board 19 in a flat manner, but it may be slackened and bulged downward as shown in FIG.

[0027] Furthermore, in the above embodiment, the ceiling panel 19 has a metal mesh sheet 19m attached to a planar frame 19f, but as shown in Figure 7, the ceiling panel 19' may also be constructed by attaching the metal mesh sheet 19m to the entire three-dimensional frame 19f'. Here, the metal mesh sheet 19m is attached to six faces of a rectangular parallelepiped that is square when viewed from above. In this case, the number of reflective surfaces becomes multiple, allowing for more complex optical effects to be produced (see Figure 8).

[0028] Furthermore, in the above embodiment, the metal mesh sheet is fixed to the frame, but if the metal mesh sheet has a certain degree of rigidity, it is possible to fold the ends to create a square edge and use this square edge in place of the frame.

[0029] Furthermore, in the above embodiment, the metal mesh sheet is formed by weaving ultra-fine stainless steel wires, but other metal wires may also be used. For example, it can be formed by weaving ultra-fine copper or aluminum wires used in electrical wiring. When copper wire is heated with a burner, it changes color depending on the temperature, allowing for a variety of expressions to be expressed by the diffusely reflected light.

[0030] Furthermore, in the above embodiment, a lighting fixture is used as a light source, but the light source may also be a skylight. In this case, the skylight portion is used as the upper ceiling, and a suspended ceiling having the above-mentioned configuration is installed below it as the lower ceiling. [Explanation of symbols]
