[Prior art]

 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 with an adhesive has been used as a decorative material for interior. By the way, when this panel is to be installed over a long wall, it is worked by abutting one by one, and at this time, it is difficult to determine the step or gap in the joint portion and the appearance is not damaged. For example, a method in which a corner of a side surface is obliquely cut, or a method in which a constant gap is provided between adjacent panels and a gap is sealed with a resin is generally used.

[0003]

[Problems to be solved by the present invention]

 However, the wall surface constructed by such a method may shrink over time due to the construction conditions and the materials that make up the panel, resulting in the formation of steps or gaps in the joints. There was an unsightly appearance. In addition, in the method of providing a gap and sealing with a resin, it is technically difficult to provide a constant gap and the corners of the panel may be missing during the construction, which makes the construction work complicated. At the same time, the construction work itself required considerable skill.

The present invention has been studied in view of such a situation. The purpose of the present invention is that the construction work is easy, and the joints generated when the construction is performed by abutting against the wall surface are beautiful. One is to provide a panel for wall surfaces where it is difficult to identify the steps and gaps that occur during construction.

[0005]

[Means for Solving the Problems] That is, the above-mentioned problem is that when the upper and lower sides of a pair of opposed side surfaces of a rectangular parallelepiped base material are machined into convex curved surfaces, straight portions remain on the side surfaces. In addition, the base layer is machined so that the radius of curvature of the upper curved surface is larger than that of the lower curved surface to form a base material layer. The problem can be solved by continuously coating the portion, the lower curved surface, the straight line portion, the upper curved surface, and the surface with a diallyl phthalate resin-based cosmetic 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 a wood-based material such as plywood, particle board, MDF (medium density fiber board), laminated wood, or a composite material in which these are compounded, or silica. Inorganic materials such as calcium board, cement calcium silicate board, asbestos cement calcium silicate board, and asbestos slates can be mentioned, but it is preferable that shrinkage over time due to temperature, humidity, etc. is less than that of wood material. It is preferable to use an inorganic material, and in particular, a calcium silicate plate and a cement calcium silicate plate which are excellent in workability and strength are preferable. The thickness of the base material is appropriately determined in consideration of strength, handleability and the like.

When a pair of side surfaces facing each other of a rectangular parallelepiped base material are installed by abutting the side surfaces of the wall surface panel, a gap is generated due to a step difference in joints and contraction of the base material after the installation. However, in order to make it difficult to visually recognize the gap, the upper curved surface (2) is cut into a convex curved surface such that the radius of curvature of the upper curved surface (2) is larger than that of the lower curved surface (3), Also, it is desirable to leave the linear portion (5) as the base material layer (1) so as to form the lower curved surface (3) and to serve as a reference surface when the wall surface panel is butted and constructed.

If the radius of curvature of the upper curved surface (2) is made smaller than that of the lower curved surface (3), the joints when the side surfaces of the wall surface panel are abutted with each other form an acute groove, so that a planar connection is achieved. It looks like burial and makes it easier to see the steps visually. If the radius of curvature of the upper curved surface (2) is made smaller than the radius of curvature of the lower curved surface (3), the gap between the wall surface and the lower curved surface (3) will increase due to the abutment of the wall panel. However, if a gap is formed in the joint portion over time, it is not preferable because it is easy to visually recognize the background of the wall surface. Furthermore, if there is no straight line portion (5), all the side surfaces of the wall panel will be curved, and the workability during butt construction will be poor.

With respect to the lower curved surface (3), not only does it function effectively because it forms the aforementioned voids, but it also prevents chipping during construction and bends the diallyl phthalate resin-based cosmetic sheet (4). This is one of the important constitutional requirements of the present invention, because it also makes it easier and prevents cracking. However, in the lower curved surface (3), the diallyl phthalate resin-based cosmetic sheet (4) should not be bent.

As for the thickness of the rectangular parallelepiped base material, it is desirable to select a thickness of 5 to 30 mm in view of strength and handleability. If it exceeds, the weight will be heavy and the handling will be poor. When the thickness of the base material is 5 to 30 mm, as a concrete example satisfying the requirements described so far, the upper corner of the base material is 3 to 6 mmR and the lower corner is a convex type with a radius of curvature of 1 to 2 mmR. The curved surface may be cut to form the upper curved surface (2) and the lower curved surface (3).

The diallyl phthalate resin-based cosmetic sheet (4) is a resin obtained by modifying a base paper for a decorative board with a diallyl phthalate resin or, further, with a melamine resin, an unsaturated polyester resin, a guanamine resin or the like. It is preferable that it is impregnated with, and then thermocompression-molded, which is particularly excellent in flexibility and has a bendability of 1 to 6 mmR under normal temperature or heating conditions. A long product that is advantageous in terms of use, such as Aika Flexi, Aika Duplex, and Aika Exshi (manufactured by Aika Kogyo Co., Ltd.) are recommended as commercially available products.

In order to coat the base material layer (1) with the diallyl phthalate resin-based cosmetic sheet (4), a pasting process may be performed using a conventionally known adhesive suitable for both materials. Examples thereof include water-based vinyl urethane adhesives, urethane adhesives, urea adhesives, vinyl acetate adhesives, epoxy adhesives, and synthetic rubber adhesives. In particular, a water-based vinyl urethane adhesive or vinyl acetate adhesive is used on the surface of the base material layer (1), and the bending adhesion portion of the diallyl phthalate resin cosmetic sheet (4), that is, , A part of the back surface linear part (6) of the base material layer (1), the lower curved surface (3), the linear part (5) and the upper curved surface (2) are made of a synthetic rubber adhesive having a strong initial adhesive force. By doing so, it is possible to obtain a wall panel with excellent bonding quality.

Although it is acceptable to cover the entire periphery of the base material layer (1) with the diallyl phthalate resin-based cosmetic sheet (4), it is necessary to cover the entire periphery because it is for a wall surface whose back surface cannot be seen. There is no need to protect the lower curved surface (3), and when stacking with the front surface facing up and storing, a part of the back surface linear portion of the base material layer (1) extending longer than the radius of curvature of the upper curved surface (2). It is desirable to coat (6). This is because when the wall panels are stored in the stacked state, the diallyl phthalate resin-based decorative sheet (4) that covers a part (6) of the back straight part is protected by the wall panel or protective material. It is intended to prevent peeling over time when pressed, which is also an important constituent feature of the present invention. As a specific example of satisfying this requirement, when the thickness of the base material is 5 to 30 mm, a part (6) of the back straight portion is set to a range of 4 to 20 mm.

[0014]

[Effect of device]

 Since the wall panel of the present invention has a straight portion on the side surface, it can be easily butt-installed, and since it has upper and lower curved surfaces on the side surface, it visually recognizes steps in joints and gaps that occur over time. It is extremely difficult to do so, and since the diaryl phthalate resin-based cosmetic sheet is coated so as to include a part of the straight line on the back surface, the lower corners are not chipped and the diallyl phthalate resin-based cosmetic sheet is not damaged. Does not peel off.

Furthermore, when an inorganic material, particularly a calcium silicate plate, a cement calcium silicate plate, or an asbestos cement calcium silicate plate is used as the base material, the base material layer has very little shrinkage and is excellent in strength. Therefore, it becomes more difficult to visually recognize steps and gaps.
