BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel.

[0002]

2. Description of the Related Art Conventionally, a wooden material, an inorganic material, or a panel obtained by combining a decorative plate with these materials via an adhesive has been used as a decorative material for interior. By the way, when this panel is constructed over a long wall surface, it is constructed by abutting one by one, and at this time, it is difficult to distinguish steps or gaps in joints, and means that does not impair the appearance, For example, a method of cutting a corner of a side surface obliquely, or a method of providing a fixed interval between adjacent panels and sealing a gap portion with a resin are generally used.

[0003]

[Problems to be solved by the present invention] However, the wall surface constructed by such a method shrinks with time due to the conditions at the time of construction and the temperature and humidity of the material constituting the panel. In some cases, a step or a gap may occur in the part, and the appearance is unsightly. In addition, in the method of providing a space and sealing the space with a resin, it is technically difficult to provide a fixed space, and the corner of the panel may be chipped during the construction, which makes the construction work complicated and However, the construction work itself required considerable skill.

[0004] The present invention has been studied in view of such a situation. The purpose of the present invention is to facilitate the construction work, and to make the joints formed when the construction is performed against the wall beautiful, Another object is to provide a panel for a wall surface in which a step or a gap generated during construction is difficult to determine.

[0005]

The object of the present invention is to provide a method for cutting a pair of opposing side surfaces of a rectangular base material into a convex curved surface so that a straight portion remains on the side surface. to, and, by cutting as the curvature of the upper curved radius becomes larger than the radius of curvature of the lower curved surface and the substrate layer, and thereafter, the original
The radius of curvature of the upper curved surface based on the side of the rectangular
Part of the straight portion of the back surface of the base layer having a longer length, the lower curved surface,
The problem can be solved by continuously covering the linear portion, the upper curved surface, and the surface with a diallyl phthalate resin decorative sheet via an adhesive. Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.

The base material used in the present invention is plywood,
Wood-based materials such as tickle board, MDF (medium density fiberboard), laminated wood,
Inorganic materials such as calcium silicate plate, calcium cement silicate plate, asbestos cement calcium silicate plate, asbestos slates, etc., are preferable. It is preferable to use an inorganic material having a small amount, and particularly preferable are a calcium silicate plate and a cement calcium silicate plate which are excellent in workability and strength. The thickness of the substrate is appropriately determined in consideration of strength, handleability, and the like.

The upper and lower sides of a pair of opposing side surfaces of a rectangular base material are formed with gaps due to steps at joints and shrinkage of the base material after the application when the side surfaces of the wall panel are abutted. Also, in order to make it difficult to grasp the gap visually, the upper curved surface (2) is cut into a convex curved surface so that the radius of curvature of the upper curved surface (2) is larger than the radius of curvature of the lower curved surface (3). It is desirable to form the lower curved surface (3) and leave the linear portion (5) as the base material layer (1) so as to serve as a reference surface when the wall surface panel is abutted and applied.

If the radius of curvature of the upper curved surface (2) is smaller than the radius of curvature of the lower curved surface (3), the joints formed when the side surfaces of the wall panel abut against each other have an acute-angled groove shape, so that they are connected flatly. And it becomes easier to see the steps as visual perception.
Further, when the radius of curvature of the upper curved surface (2) is smaller than the radius of curvature of the lower curved surface (3), the gap formed between the wall surface and the lower curved surface (3) becomes larger by abutting the wall panels, so that joints are formed. If a temporal gap is generated in the portion, it is not preferable because the background of the wall surface is easily visually recognized. Furthermore, if there is no linear part (5), all the side surfaces of the wall panel become curved surfaces, and the workability at the time of butt construction is deteriorated.

The lower curved surface (3) not only functions effectively to form the above-mentioned voids, but also prevents chipping at the time of construction, and provides a diallyl phthalate resin-based decorative sheet (4).
It is also one of the important components of the present invention because it also makes it easier to bend and prevents cracking. However, in the lower curved surface (3), the diallyl phthalate resin-based decorative sheet (4) must not be bent.

The thickness of the rectangular base material is preferably 5 to 30 mm in consideration of strength and handleability. If the thickness is less than the lower limit, the strength is inferior and the material tends to be damaged. If it exceeds, the weight becomes heavy and the handleability is poor.
When the thickness of the substrate is 5 to 30 mm, as a specific example satisfying the requirements described above, the upper corner of the substrate is 3 to 6 m
An upper curved surface (2) and a lower curved surface (3) are formed by cutting a mR and a lower corner into a convex curved surface with a radius of curvature of 1 to 2 mmR.

As the diallyl phthalate resin decorative sheet (4), a base paper for decorative board is made of diallyl phthalate resin or a resin modified with melamine resin, unsaturated polyester resin, guanamine resin or the like. An impregnation treatment, followed by hot-press molding, is particularly preferable, which is excellent in flexibility and has a bendability of 1 to 6 mmR under normal temperature or heating conditions, and is preferably economical. Advantageous long products, for example, as commercial products, Aika Flexi, Aikadaplex, and Aika Exci (all manufactured by Aika Kogyo) are recommended.

In order to cover the base material layer (1) with the diallyl phthalate resin-based decorative sheet (4), a conventional known adhesive suitable for both materials may be used for bonding. And aqueous vinyl urethane adhesives, urethane adhesives, urea adhesives, vinyl acetate adhesives, epoxy adhesives, and synthetic rubber adhesives.
In particular, on the surface of the base material layer (1), an aqueous vinyl urethane-based adhesive or a vinyl acetate-based adhesive is used, and a bent adhesion portion of the diallyl phthalate resin-based decorative sheet (4), that is, A synthetic rubber adhesive having a strong initial adhesive force is used for a part (6) of the back surface linear portion of the base material layer (1), the lower curved surface (3), the linear portion (5), and the upper curved surface (2). Then, it is possible to obtain a wall panel having excellent bonding quality.

Although it is possible to cover the entire periphery of the base material layer (1) with the diallyl phthalate resin-based decorative sheet (4), it is not necessary to cover the entire periphery because the back surface is not visible. , When protecting the lower curved surface (3) and storing it with the surface facing up , the side of the original rectangular base material
With a length greater than the radius of curvature of the upper curved surface (2) based on
It is desirable to cover a part (6) of the back surface linear portion of the base material layer (1) . This is because when the wall panel is stored in an overlying state, the diallyl phthalate wood-based decorative sheet (4) covering a part (6) of the back straight part is pressed by the wall panel or the protective material. By doing
This is to prevent peeling over time, which is also an important component of the present invention. As a specific example that satisfies this requirement, when the thickness of the base material is 5 to 30 mm, a part in which the part (6) of the straight portion on the back surface has a range of 4 to 20 mm can be fisted.

[0014]

[Effects of the Invention] The wall panel of the present invention has a straight portion on the side surface, so that it is easy to perform abutting work,
Because there are upper and lower curved surfaces on the side surface, it is extremely difficult to visually grasp the gaps in the joints and gaps that occur over time, and the diallyl phthalate resin-based decorative sheet is covered so as to include a part of the back straight part The lower corner is not chipped, and the diallyl phthalate resin-based decorative sheet does not peel off.

Further, when an inorganic material, in particular, a calcium silicate plate, a cement calcium silicate plate, or an asbestos cement calcium silicate plate is used as the base material, the shrinkage of the base material layer is extremely small and the strength is excellent. ,
This makes it difficult to visually grasp the steps and gaps.
