Description

[Technical field]

[0001] The present invention relates to a ceiling material, and more particularly to a ceiling material applied to ceilings of halls, entrance halls, corridors, etc. of large facilities, which allows for more flexible use of thin and lightweight ceiling panels. [Background technology]

[0002] System ceilings, which can be constructed quickly and with fewer components, are widely used for ceilings in large facilities such as buildings. System ceilings are usually constructed by suspending multiple joist supports horizontally with hanging bolts attached to the ceiling slab, attaching multiple joists made of flanged steel beams or the like perpendicular to the joist supports, and hanging panel-shaped ceiling panels on the flanges of the joists.

[0003] For example, a system ceiling has been proposed in which a ceiling grid module, which is preassembled with hat-shaped steel in a grid pattern, is attached to a raceway that functions as a joist support, and rectangular plasterboard is dropped into the lattice portion of the ceiling grid module (Patent Document 1). Also proposed is a ceiling structure in which rectangular ceiling materials (ceiling panels) made of rock wool are screwed directly to the joists, and the fiber direction of the ceiling panels is perpendicular to the length direction of the joists, thereby suppressing the deflection of the ceiling panels (Patent Document 2).

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-181948 [Patent Document 2] JP 2018-150723 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the above-mentioned system ceiling is intended to improve workability, but from the viewpoint of the ceiling panel mounting structure and safety, it is required to use lighter ceiling panels. However, the thinner the ceiling panel is, the more it is required to reduce its weight. However, the thinner the thickness, the more likely it is to cause problems with bending. Therefore, in reality, the thickness is ensured so that the rigidity is not lost, and the area of ​​each panel is set small, and there is also a problem that the range of choices for the material of the ceiling panel is narrow. As a result, there is also a problem of low freedom of design.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a ceiling material to be applied to ceilings of large facilities such as buildings, which allows the use of thinner ceiling panels and also allows the use of ceiling panels with a larger area, thereby allowing for greater freedom in design. [Means for solving the problem]

[0007] In order to solve the above problems, in the present invention, a penetrating support material is used that has a support portion that supports the underside of the ceiling panel and a through portion that penetrates into a through hole provided in the ceiling panel, thereby supporting the ceiling panel in a suspended state relative to the ceiling base structure, and by providing a connecting means that structurally connects the multiple through portions of the penetrating support material, a stiffening structure is formed for the ceiling panel and deflection of the ceiling panel is suppressed.

[0008] In other words, the gist of the present invention lies in a ceiling material that is attached to a ceiling base structure to form a ceiling, and is composed of a ceiling panel that forms the design of the ceiling, and a plurality of penetrating support materials that penetrate the ceiling panel from the underside of the ceiling to support the ceiling panel on the ceiling base structure, each of the penetrating support materials has a support portion that supports the underside of the ceiling of the ceiling panel and a penetrating portion formed on an upper portion of the support portion, the ceiling panel is provided with a plurality of through holes through which the support portions of the penetrating support materials do not pass but the penetrating portions pass, and the penetrating support materials are equipped with connecting means that structurally connect the plurality of penetrating portions. Effect of the Invention

[0009] According to the ceiling material of the present invention, when the ceiling panel is supported in a suspended state, the connecting means that structurally connects the multiple penetration parts of the penetration support material forms a stiffening structure for the ceiling panel and suppresses the deflection of the ceiling panel, so that a thinner ceiling panel and a larger ceiling panel can be used. Therefore, various materials can be used for the ceiling panel, and more freedom in design is possible. [Brief description of the drawings]

[0011] An embodiment of the ceiling material according to the present invention will be described with reference to the drawings. The ceiling material of the present invention is a ceiling material that is attached to a ceiling substrate structure to form a ceiling, and is suitable for halls, entrance halls, corridors, etc. in large facilities such as buildings. In the following description of the embodiment, the indoor side below the ceiling board is referred to as "under the ceiling," and the ceiling substrate side above the ceiling board is referred to as "above the ceiling."

[0012] As shown in Figures 1 and 3, the ceiling material of the present invention is mainly composed of a ceiling board 1 that constitutes the design of the ceiling, and a number of penetrating support members 2 that penetrate the ceiling board from the underside of the ceiling and support the ceiling board 1 on a ceiling foundation structure. Usually, the ceiling foundation structure is a conventionally known foundation structure that is composed of a number of suspension bolts 5 attached to the ceiling slab or ceiling batten of the building, a number of joist supports 6 suspended horizontally in parallel and in a row by these suspension bolts 5, and a number of joists 7 suspended at a fixed pitch on the underside of the joist supports 6.

[0013] The ceiling board 1 is made of various flame-retardant thin plates made of various metal materials, resin materials, or inorganic materials such as rock wool. For example, the ceiling board 1 may be made of a composite board in which metal sheets are laminated on both sides of a resin sheet. In such a composite board, the metal sheets are sheets of about 0.2 to 0.5 mm thick made of metals such as aluminum or aluminum alloys, stainless steel, iron, copper, titanium, tin, and nickel, and the core resin sheets are sheets of about 0.6 to 5.0 mm thick made of thermoplastic resins such as polyolefins such as polyethylene and polypropylene, polyvinyl chloride, polyamide, polycarbonate, polystyrene, polyhydroxyl ether, and vinyl acetate. The composite board as described above is manufactured by superposing, for example, aluminum sheets on both sides of a melt-extruded synthetic resin sheet and passing it between rotating rolls, in which the metal sheets on both sides are adhered to the resin sheets via an adhesive. Such a composite board is available, for example, as "Alpolic" (trade name) manufactured by Mitsubishi Chemical Infratec Corporation.

[0014] Moreover, the ceiling board 1 is usually formed in a rectangular or square planar shape with a side length of about 450 to 6000 mm. The ceiling board 1 is provided with a plurality of through holes 1c through which the support parts 21 of the penetrating support members 2 described below do not pass and only the penetrating parts 22 of the penetrating support members 2 pass in order to assemble the penetrating support members 2 that support the ceiling board. The shape and arrangement of the through holes 1c are set according to the form of the penetrating support members 2 (indicated by the reference symbol 2A in Figs. 1 and 2, the reference symbol 2B in Figs. 3, 4 and 5, the reference symbol 2C in Fig. 6, and the reference symbol 2D in Fig. 7).

[0015] On the other hand, the penetrating support material 2 has a support part 21 that supports the underside of the ceiling of the ceiling board 1, and a through part 22 formed on the upper part of the support part 21 for insertion into the through hole 1c of the ceiling board 1. Furthermore, the penetrating support material 2 is provided with a connecting means that structurally connects the multiple through parts 22 of the penetrating support material 2 to form a stiffening structure for the ceiling board 1. In the present invention, two embodiments can be mentioned depending on the shape of the penetrating support material 2 and the above-mentioned connecting means.

[0016] First, the first embodiment of the present invention will be described. In the ceiling material according to the first embodiment, as shown in Fig. 1 and Fig. 2, the penetrating support material 2A is composed of a flat plate-like member with multiple protrusions formed on the upper side of a horizontally long band-like shape when viewed from the side. The band-like parts are configured as the support parts 21 and the connecting means, and each protrusion is configured as a penetrating part 22. In other words, the penetrating support material 2A is configured as one member by connecting multiple parts with a convex planar shape with connecting parts 3a (the parts indicated by the dashed lines in Fig. 1), and the connecting parts 3a function as the connecting means.

[0017] The dimensional specifications of the penetrating support material 2A can be appropriately designed in consideration of the area, strength and design of the ceiling board 1, but for example, the thickness of the penetrating support material 2A is set to about 1 to 50 mm, the horizontal length of the penetrating support material 2A is set to about 450 to 6000 mm, the height of the support part 21 (width of the strip part) is set to about 20 to 1500 mm, and the protruding height of the penetrating part 22 from the support part 21 is set to about 10 to 500 mm. The arrangement pitch of the penetrating parts 22 in the penetrating support material 2A is set to about 200 to 2000 mm, for example. Furthermore, the penetrating part 22 of the penetrating support material 2A is provided with a through hole 2a for mounting a hanging spring 4 as a hanging fitting in order to hang the penetrating support material 2A from the above-mentioned joist 7.

[0018] When the penetrating support material 2A is used, the ceiling board 1 is provided with a plurality of slit-shaped through holes 1c along the length direction of the penetrating support material 2A to be placed at the positions corresponding to the penetrating portion 22. The hanging spring 4 to be attached to the through hole 2a of the penetrating portion 22 is an elastic body made of a steel wire or the like formed in a substantially U-shape with a flat bottom and a gradually expanding width toward the upper end, and the upper end is provided with a hanging portion bent toward the outside of the U-shape. The hanging hole 7 for hanging the hanging spring 4 is provided in the joist 7 constituting the ceiling foundation structure at a position corresponding to the penetrating portion 22 of the penetrating support material 2A. The hanging hole 7c is formed as an elongated hole extending in a direction perpendicular to the through hole 1c of the ceiling board 1 so as to correspond to the expansion and contraction direction of the hanging spring 4 to be attached to the through hole 2a.

[0019] In the construction of the ceiling material of the first embodiment, the penetrating support material 2A is placed from the underside of the ceiling of the ceiling board 1 with the ceiling board 1 raised to the underside of the joist 7, and the penetrating portion 22 of the penetrating support material is inserted into the through hole 1c of the ceiling board 1. Then, in the ceiling space, the hanging spring 4 is passed through the through hole 2a of the penetrating portion 22 protruding from each through hole 1c of the ceiling board 1, and then the hanging spring 4 is compressed and its upper end is inserted into the hook hole 7c of the joist 7 and released. As a result, the hanging portion at the upper end of the hanging spring 4 expands, so that the penetrating support material 2A can be hung from the joist 7 via the hanging spring 4, and the ceiling board 1 can be laid.

[0020] That is, in the first embodiment, the penetrating support material 2A has a support part 21 that supports the ceiling underside surface of the ceiling board 1 and a through part 22 that penetrates the through hole 1c provided in the ceiling board 1, and supports the ceiling board 1 in a suspended state via a hanging spring 4 as a hanging metal fitting to the ceiling base structure. At that time, the penetrating support material 2A is provided with a connecting part 3a as a connecting means that structurally connects the multiple through parts 22, in other words, the penetrating support material 2A is configured as an integral part, so that the penetrating support material 2A forms a stiffening structure for the ceiling board 1 and can suppress the deflection of the ceiling board 1. Therefore, according to the ceiling material according to the first embodiment of the present invention, a thinner ceiling board 1 can be used, and a larger area of ​​the ceiling board 1 can be used, and the ceiling board 1 can be configured with various materials.

[0021] Next, the second embodiment of the present invention will be described. In the ceiling material according to the second embodiment, as shown in Figs. 3 and 4, the penetrating support material 2B is, for example, a flat plate-like member formed in a convex shape when viewed from the side. In such a penetrating support material 2B, the broad, approximately lower half of the convex shape is configured as the support part 21, and the protrusion of the approximately upper half is configured as the through part 22. That is, the penetrating support material 2B is configured as a top-shaped member having one each of the support part 21 and the through part 22, and is provided with a connecting bar 3b arranged on the ceiling back surface of the ceiling board 1 as a connecting means. The multiple penetrating support materials 2B are configured so that when they are arranged, the through parts 22 are connected to each other by inserting the connecting bar 3b into the insertion hole 2b provided in the through part 22.

[0022] The dimensional specifications of the penetrating support material 2B are, for example, a thickness of about 1 to 50 mm, a width of the support portion 21 of about 30 to 500 mm, a height of about 20 to 1500 mm, a width of the through portion 22 of about 20 to 490 mm, and a protruding height of the through portion 22 from the support portion 21 of about 10 to 500 mm. Furthermore, the through portion 22 is provided with, for example, a square or rectangular insertion hole 2b for inserting the connecting bar 3b therethrough. The insertion hole 2b is formed to a size that will not cause loosening when the connecting bar 3b is inserted therethrough.

[0023] The connecting bar 3b is a rod-shaped member for reinforcing the ceiling board 1 via a plurality of penetrating support members 2B, and is made of a rectangular tubular aluminum steel member, etc. The cross section perpendicular to the longitudinal direction of the connecting bar 3b is formed into a rectangle with each side measuring approximately 10 to 400 mm, and the length of the connecting bar 3b is set to be approximately equal to the length of the ceiling board 1.

[0024] When the penetrating support material 2B is used, the ceiling board 1 is provided with a plurality of elongated slit-shaped through holes 1c that are perpendicular to the longitudinal direction of the ceiling board (extension direction of the connecting bar 3b) as shown in Fig. 3. The arrangement pitch of the through holes 1c in the ceiling board 1, i.e., the arrangement pitch of the penetrating support material 2B, is, for example, about 200 to 2000 mm. When the penetrating support material 2B is used, the connecting bar 3b can be directly attached to the furring beam receiver 6 using screws 8 such as tapping screws, without arranging a furring beam in the ceiling foundation structure.

[0025] In the construction of the ceiling material of the second embodiment, before laying the ceiling board 1, the through-holes 22 of the multiple penetrating support materials 2B are inserted into the through-holes 1c of the ceiling board from the underside of the ceiling of the ceiling board 1, and the connecting bar 3b is passed through the insertion hole 2b of each penetrating part 22 protruding from the ceiling back side (upper surface side) of the ceiling board 1, and these penetrating parts 22 are connected by the connecting bar 3b. As a result, a ceiling board 1 in which multiple penetrating support materials 2B are attached to the ceiling underside surface of the ceiling board 1 and the connecting bar 3b is arranged on the ceiling back side surface of the ceiling board 1, and the penetrating support materials 2B and the connecting bar 3b are integrated can be constructed. Then, as shown in Figures 4 and 5, the ceiling board 1 can be laid by placing the ceiling board 1 on the underside of the joist support 6 and fixing it to the joist support 6 with screws 8 in the ceiling back.

[0026] That is, in the second embodiment, the penetrating support material 2B has a support part 21 that supports the ceiling underside surface of the ceiling board 1, and a through part 22 that penetrates the through hole 1c provided in the ceiling board 1, and is provided with a connecting bar 3b as a connecting means for connecting the plurality of penetrating support materials 2B to each other. Then, the connecting bar 3b is fixed to the ceiling base structure (rafter 6) with a screw 8, so that the ceiling board 1 is supported in a suspended state via the penetrating support material 2B. At that time, the connecting bar 3b as a connecting means structurally connects the through parts 22 of the plurality of penetrating support materials 2B, and these connected penetrating support materials 2B form a stiffening structure for the ceiling board 1, so that the deflection of the ceiling board 1 can be suppressed. Therefore, as in the first embodiment, according to the ceiling board according to the second embodiment of the present invention, a thinner ceiling board 1 can be used, and a larger area of ​​the ceiling board 1 can be used, and the ceiling board 1 can be constructed with various materials.

[0027] In the second embodiment, instead of the flat plate-like penetrating support material 2B shown in Figures 3 to 5, a three-dimensional penetrating support material 2 as shown in Figures 6 and 7 can be used. The penetrating support material 2C shown in Figure 6 has a member body formed in a cylindrical shape, and when viewed with the center line perpendicular, approximately the lower half of the cylinder is configured as the penetrating support material 21, and approximately the upper half of the cylinder has symmetrically positioned 1 / 4 circumference portions cut out and adjacent 1 / 4 circumference portions configured as penetrating portions 22, with insertion holes 2b opened in the penetrating portions 22.

[0028] The dimensional specifications of the penetrating support material 2C are set, for example, as follows: outer diameter about 50 to 500 mm, overall height about 20 to 1500 mm, and rising height of the penetrating part 22 from the support part 21 about 10 to 500 mm. The insertion hole 2b through which the connecting bar 3b is inserted is similar to the embodiment shown in Figs.

[0029] When the penetrating support material 2C is used, a plurality of arch-shaped slits are provided as through holes in the ceiling board 1 at positions corresponding to the penetrating portions 22. In constructing a ceiling material using the penetrating support material 2C, similarly to the case of the penetrating support material 2B, the penetrating portions 22 of the penetrating support material 2C are inserted into the through holes 1c of the ceiling board 1 from the underside of the ceiling, and the connecting bar 3b is passed through the insertion holes 2b of the penetrating portions 22 protruding from the ceiling back side (upper surface side) of the ceiling board 1, and these penetrating portions 22 are connected by the connecting bar 3b to form the ceiling board 1 in which the penetrating support material 2B and the connecting bar 3b are integrated, and then the ceiling board 1 is laid on the underside of the joist support 6.

[0030] Furthermore, in the penetrating support material 2D shown in Figure 7, the main body is formed into a square tube shape, and when viewed with the center line vertical, approximately the lower half of the square tube is configured as the penetrating support material 21, and approximately the upper half of the square tube has two opposing side portions cut out and the adjacent two side portions configured as a penetrating portion 22, and an insertion hole 2b is opened in such penetrating portion 22.

[0031] The dimensional specifications of the penetrating support material 2D are set, for example, as follows: side width about 50 to 500 mm, overall height about 20 to 1500 mm, and rising height of the penetrating part 22 from the support part 21 about 10 to 500 mm. The insertion hole 2b through which the connecting bar 3b is inserted is similar to the embodiment shown in Figs.

[0032] When the penetrating support material 2D is used, a plurality of elongated slit-shaped through holes 1c perpendicular to the longitudinal direction of the ceiling board (extension direction of the connecting bar 3b) are provided in the ceiling board 1. In the construction of a ceiling material using the penetrating support material 2D, similar to the case of the penetrating support material 2B, the penetrating parts 22 of the penetrating support material 2D are inserted into the through holes 1c of the ceiling board from the underside of the ceiling board 1, the connecting bar 3b is passed through the insertion holes 2b of each penetrating part 22 protruding from the ceiling back side (upper surface side) of the ceiling board 1, and these penetrating parts 22 are connected by the connecting bar 3b to form the ceiling board 1 in which the penetrating support material 2B and the connecting bar 3b are integrated, and then the ceiling board 1 is laid on the underside of the joist support 6.

[0033] As described above, with the ceiling material according to the present invention, when the ceiling board 1 is supported in a suspended state, the connecting means that structurally connects the multiple penetration parts 22 of the penetration support material 2 forms a stiffening structure for the ceiling board 1 and suppresses the deflection of the ceiling board 1, so that a thinner ceiling board 1 can be used, a ceiling board 1 with a larger area can be used, and the ceiling board 1 can be made of various materials. This allows for greater freedom in design.

[0034] Furthermore, the ceiling material according to the present invention makes it possible to expand the design range of the ceiling board 1 itself, and by devising the shape and arrangement of the penetrating support material 2, both the ceiling board 1 and the penetrating support material 2 can be configured as design parts. Furthermore, when the penetrating support material 2C shown in Fig. 6 and the penetrating support material 2D shown in Fig. 7 are used, lighting fixtures can be placed inside the tubes of these penetrating support materials 2, thereby enhancing functionality.

[0035] Furthermore, as shown in Figs. 8 and 9, in the ceiling material according to the present invention, the ceiling board 1 is not limited to a flat member, and a gently curved, wavy ceiling board can also be used. For example, in the second embodiment, when a wavy ceiling board 1 is used, the same penetrating support material 2B as shown in Fig. 3 above is used, and a curved connecting bar 3b corresponding to the wavy shape of the ceiling board 1 is arranged. In addition, in order to add a fixing part to the joist support 6, the penetrating support material 2B may be arranged at a position away from the connecting bar 3b, and the penetrating support material 2B may be fixed with a plug-in fastener 3c. When a wavy ceiling board 1 is used, not only the design can be changed, but also the acoustic characteristics can be changed. [Industrial Applicability]

[0036] When the ceiling material of the present invention is supported in a suspended state, the deflection of the ceiling board 1 is suppressed by the penetrating support material 2, so that a thinner ceiling board 1 with a larger area can be used, allowing for greater freedom in design, making it ideal for construction of ceilings in large facilities such as buildings.
