Description

  The present invention relates to a method for attaching a decorative panel.

  Conventionally, examples of wall surfaces that use rust-proof metal studs include office wall partitions, school toilet wall partitions, condominium partitions, store wall partitions, and residential kitchen wall surfaces.

However, since the decorative panel is attached after the gypsum board is pasted, there was a problem of dust and disposal of the gypsum board at the time of dismantling.
In order to solve this problem, it is possible to fix with a screw, but there is a problem that the screw deteriorates the appearance.
In order to solve such a problem, Japanese Patent Application Laid-Open No. 2004-68316 discloses a method using a magnet. However, there is a case where a float is generated at a portion where a sheet magnet is not attached.

JP 2004-68316 A JP 2004-65710 A

The present invention has been studied in view of such a situation, and simple mounting and dismantling is realized by a strong sheet magnet, and a special metal fitting is used so that the decorative panel can be easily positioned and attached. It is characterized by preventing.
That is, according to the first aspect of the present invention, the sheet-shaped magnet 7 is attached to places on the back surface of the decorative panel 1 through the magnetic adherend, and the metal fitting 2 having a hat-shaped cross section is brought into contact with the sheet-shaped magnet 7. This is a method of attaching the decorative panel 1, wherein the metal fitting 2 is attached to the ground.
According to the second aspect of the present invention, the screw hole 4 is formed in the flange portion 2a of the metal fitting 2 having the hat-shaped cross section, and the pin hole 3 is formed in the refracting portion 2c between the flange portion 2a and the vertical portion 2b. The method for attaching a decorative panel (1) according to claim 1, wherein the metal fitting (2) is fixed with screws or pins.

According to the present invention, even if the base is a gypsum board, the metal fitting can be fixed with a pin, so that dust is not generated during construction or dismantling. Moreover, it looks good, can be easily constructed and dismantled, and can be performed dry, and does not require skill.
Furthermore, since the air permeability is ensured, the decorative panel does not warp.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is an exploded configuration cross-sectional view showing a state in which sheet magnets 7 are attached to places on the back surface of a decorative panel 1 according to the present invention via a rust-proof steel plate 6 as a magnetic adherend and are in contact with a metal fitting 2. It is. The rust-proof steel plate 6 is bonded to the decorative panel 1 with a double-sided adhesive tape 5.

  As the decorative panel 1, a melamine resin decorative board having a thickness of 3 mm is used. Other than the melamine resin decorative board, there is no particular limitation as long as it has designability, water resistance, heat resistance, and rigidity. Or decorative boards, such as a polyester resin decorative board and a diallyl phthalate resin decorative board obtained by film-forming using unsaturated polyester resin, are applicable. Desirably, it is preferable to use a cast or a melamine resin decorative board that has excellent performance in stain resistance and abrasion resistance and is not easily damaged.

  A rare earth sheet magnet is used as the sheet magnet 7. Magnets include ferrite magnets and alnico magnets in addition to rare earth magnets, but as the size of the decorative panel increases and the thickness increases, the magnet becomes heavier and therefore requires higher magnetic force. Rare earth magnets having a higher magnetic flux density than magnets and alnico magnets are particularly preferred.

  Rare earth magnets are scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, eurobium, gadolinium, terium, dysprodium, holmium, erbium, thulium, ytterbium, lutetium, and other rare earth metals mixed with magnetic materials. The magnetic sheet is made by kneading and softening a rare earth magnetic powder, a resin binder such as a synthetic rubber or a thermoplastic synthetic resin, a coupling agent, a vulcanizing agent, an anti-aging agent, and the like. A sheet is formed by extrusion molding, injection molding, calendar molding, or the like, and a magnetic field is applied.

  The particle size of the rare earth magnetic powder is preferably 20 to 150 μm, and the blending ratio is preferably 75 to 95% by weight. When the particle size is small, the magnetic properties are likely to deteriorate, and when the particle size is large, the orientation of the magnet powder is deteriorated. The greater the blending ratio, the better the magnetic properties, but if it exceeds 95% by weight, the magnetic sheet becomes brittle.

  As the rare earth-based magnetic material, those having a large residual magnetic flux density, coercive force, and maximum energy product are particularly preferable. In terms of composition, samarium-cobalt, samarium-iron-nitrogen, neodymium-iron-boron, cerium-cobalt. In the present invention, a neodymium-iron-boron system is used.

  Synthetic rubbers include nitrile rubber, nitrile-butadiene rubber, silicone rubber, urethane rubber, fluorine rubber, acrylic rubber, butyl rubber, etc., and thermoplastic synthetic resins include vinyl chloride elastomer, styrene elastomer, olefin Examples of such elastomers include polyester elastomers, polyester elastomers, polyamide elastomers, and urethane resins. In the present invention, nitrile-butadiene rubber is used.

  Examples of the rust-proof steel plate 6 as the magnetic adherend include those in which a metal foil such as Al, Ti, Fe, Cu, Nb, and SUS is wound, and a surface-treated steel plate in which the surface of the steel plate is rust-proofed. In the present invention, an electrogalvanized steel sheet (trade name: Bonde Steel Sheet, manufactured by Nippon Steel Corp.) is used. Other surface-treated steel sheets include hot dip galvanized steel sheets, alloyed hot dip galvanized steel sheets, hot dip galvanized steel sheets such as hot dip galvanized steel sheets, electrogalvanized steel sheets, electric double layer alloy galvanized steel sheets, electric Examples include electrogalvanized steel sheets, turn-plated steel sheets, electrotin-plated steel sheets, etc.

  FIG. 2 is a perspective view of the metal fitting 2 having a hat-shaped cross section for magnetic attachment to the decorative panel 1, with a screw hole 4 in the flange portion 2a and a refraction portion 2c between the flange portion 2a and the vertical portion 2b. A pin hole 3 is formed. In a base that is difficult to screw, such as a gypsum board, pins are inserted through the pin holes 3 obliquely and fixed. When fastening with a pin, an instantaneous adhesive may be applied to the head of the pin for the purpose of firmly fixing to the base.

FIG. 3 is a perspective view showing a state in which the decorative panel 1 is attached to the gypsum board.
FIG. 3 is a schematic view, and there is no particular limitation on the arrangement method and size of the metal fittings.

FIG. 3 is an exploded configuration cross-sectional view showing a state in which a sheet magnet is attached to the back surface of the decorative panel via a double-sided adhesive tape and a rust-proof steel plate and is in contact with a metal fitting. The perspective view of the metal fitting used by this invention. The perspective view which shows the state which attached the decorative panel to the gypsum board.
