Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The invention relates to stone panels used, for example, as building wall and flooring.

[0002]

[Prior art]

 2. Description of the Related Art Stone panels made of marble or granite are sometimes used for decoration of walls and floors of, for example, hotel lobby and department store elevator halls. The space where the walls and floor are decorated with such stone panels is a stylish space with a sense of luxury.

[0003]

[Problems to be solved by the invention]

 A conventional stone panel is, for example, a single-layer plate-like body formed by cutting marble or granite to a thickness of, for example, about 20 mm to 30 mm. For this reason, the weight per sheet was extremely large, and handling during construction was very inconvenient. Since the weight per piece is large, it can be used as a wall material and a floor material for a reinforced building with a strong framework, but it is used as a wall material and a floor material for a wooden building such as a wooden house. I couldn't do that.

[0004] Therefore, the present invention aims to provide a lightweight stone panel.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the invention according to claim 1 comprises a urethane layer composed of a polyurethane foam, a glass fiber layer laminated on the front and back surfaces of the urethane layer, and a surface side of the urethane layer. And a natural stone layer laminated on the glass fiber layer.

Further, the stone panel according to the present invention can be said to be constituted by laminating a natural stone layer, a glass fiber layer, a urethane layer and a glass fiber layer in this order from the surface side. According to the configuration described above, the amount of natural stone used is smaller than when a stone panel of the same size is formed only of natural stones, so that the total weight of the stone panel can be reduced.

Further, since the polyurethane foam constituting the urethane layer contains air bubbles, if the urethane layer and the natural stone layer were directly bonded to each other, the urethane layer would not be applied when external force is applied. There is a possibility that the layer and the natural stone layer may be separated, but according to the present invention, since the urethane layer and the natural stone layer are joined via the glass fiber layer, the respective layers are firmly adhered. There is no possibility that the urethane layer and the natural stone layer are separated as described above.

In addition, since the glass fiber layer is provided on the back surface of the urethane layer, even if the base material of the wall surface or the floor surface is made of a material that does not adhere well to the urethane layer, a stone panel is formed on the base material. Good adhesion can be prevented, and the stone panel can be prevented from peeling off from the ground. In addition, since glass fiber is waterproof, even if moisture penetrates from the surface of the natural stone layer, the infiltrated water is absorbed by the glass interposed between the natural stone layer and the urethane layer. It is blocked by the fiber layer and does not penetrate into the urethane layer. Therefore, there is no danger that the moisture penetrating from the surface of the stone panel will corrode the foundation on the wall surface or floor surface to which the stone panel is attached.

Further, by providing the glass fiber layers on the front and back surfaces of the urethane layer, the heat insulating property and the sound insulating property of the urethane layer are improved, and the excellent heat insulating effect and the sound insulating effect can be exhibited. it can. Further, since the urethane layer and the glass fiber layer are provided on the back side of the natural stone layer, even if a strong impact is applied from the outside, the impact can be absorbed by the urethane layer and the glass fiber layer. This can prevent the natural stone layer from breaking due to impact.

[0010] The invention according to claim 2 is the stone panel according to claim 1, wherein the natural stone layer has a thickness of about 5 mm. According to this invention, the natural stone layer is as thin as about 5 mm and the glass fiber layer is provided on the back of the natural stone layer. No damage such as cracks will occur. Therefore, concrete nails can be used when attaching a stone panel to a wall surface, etc., so that the labor required for stone panel construction can be reduced.

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing a configuration of a stone panel according to an embodiment of the present invention. The stone panel 1 is used by being attached to a wall surface or the like, for example, to decorate a wall surface or a floor surface of a Western room.

The stone panel 1 is a plate-like body formed in a rectangular shape, and includes a urethane layer 11, glass fiber layers 12 and 13 provided on the front and back surfaces of the urethane layer 11, and a urethane layer 11. A natural stone layer 14 provided on the glass fiber layer 12 on the front side. In other words, the stone panel 1 has a four-layer structure in which the natural stone layer 14, the glass fiber layer 12, the urethane layer 11, and the glass fiber layer 13 are laminated in this order from the surface side.

The urethane layer 11 is formed in a flat plate shape using a polyurethane foam, and its thickness is changed according to a desired thickness of the stone panel 1, and is set, for example, to about 5 mm to 30 mm. The glass fiber layers 12 and 13 are thin sheets formed using glass fibers, and are bonded to the front and back surfaces of the urethane layer 11 with a silicone adhesive.

The natural stone layer 14 is formed, for example, by cutting a flat plate having a thickness of about 5 mm from a natural stone such as marble or granite, polishing one surface thereof to form a glossy surface 14A, and then urethane in plan view. It is made by cutting to the same size as the layer 11 and the glass fiber layers 12,13. Then, a silicone adhesive is applied to the surface of the glass fiber layer 12 on the surface side of the urethane layer 11, and the surface opposite to the glossy surface 14A of the natural stone layer 14 formed as described above is bonded to the applied surface. By doing so, this stone panel 1 can be obtained.

In the stone panel 1 thus obtained, about 5 mm of the entire thickness is constituted by the natural stone layer 14, and the rest is constituted by the urethane layer 11 and the glass fiber layers 12, 13. Therefore, it is lighter than a conventional stone panel consisting only of natural stone, and is very convenient to handle during construction and transportation.

Further, since the stone panel 1 is lightweight, it can be used not only as a wall material and a floor material of a Western room in a reinforced building having a strong framework, but also as a wall material of a Western room in a wooden building. It is also applicable as a floor material. Further, the present invention can be applied not only to the wall material and the floor material of the Western room, but also, for example, to the wall material and the floor material of a unit bath. In addition, it can be used as a table top.

Further, since the urethane layer 11 and the glass fiber layers 12, 13 are provided on the back side of the natural stone layer 14, even if a strong impact is applied from the outside, the impact is applied to the urethane layer 11 and the glass fiber layer. The natural stone layer 14 can be absorbed by the layers 12 and 13, thereby preventing the natural stone layer 14 from breaking due to impact. Further, since the urethane layer 11 and the natural stone layer 14 are bonded via the glass fiber layer 12, the respective layers are firmly adhered to each other, so that there is no possibility of peeling between the respective layers. That is, since bubbles are contained in the urethane layer 11 (polyurethane foam), the urethane layer 11 and the natural stone layer 14 are directly bonded to each other. 11 and the natural stone layer 14 may be peeled off. On the other hand, since the urethane layer 11 and the natural stone layer 14 are well bonded to the glass fiber layer 12, the configuration in which the urethane layer 11 and the natural stone layer 14 are joined via the glass fiber layer 12 has the above-described structure. There is no possibility that the urethane layer 11 and the natural stone layer 14 will peel off.

In addition, since the glass fiber layer 13 is provided on the back surface of the urethane layer 11, even if the base material of the wall surface or the floor surface is made of a material that does not adhere well to the urethane layer 11, a stone panel is provided on the base material. 1 can be satisfactorily adhered, and the stone panel 1 can be prevented from peeling off from the base. In addition, the natural stone layer 14 is as thin as about 5 mm and the glass fiber layer 12 is adhered to the back surface of the natural stone layer 14. There is no damage such as cracks. Therefore, concrete nails can be used when attaching the stone panel 1 to a wall surface, etc., so that the labor required for installing the stone panel 1 can be reduced.

Further, since the glass fiber constituting the glass fiber layer 12 is waterproof, even if moisture infiltrates from the surface of the natural stone layer 14, the infiltrated moisture is removed from the glass fiber layer 12. And does not penetrate into the urethane layer 11. Therefore, there is no possibility that the moisture permeating from the surface of the stone panel 1 will corrode the foundation on the wall surface or the floor surface to which the stone panel 1 is attached.

Further, since the glass fiber layers 12 and 13 are provided on the front and back surfaces of the urethane layer 11, the heat insulating property and the sound insulating property of the urethane layer 11 are improved, so that the stone panel 1 has an excellent heat insulating effect. And it has a sound insulation effect. The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment. For example, in the above embodiment, the stone panel is formed in a flat plate shape. However, as shown in FIG. 2, the stone panel may be formed in a curved plate shape having an arc-shaped cross section. The stone panel 2 shown in FIG. 2 is obtained, for example, by cutting a curved plate having a thickness of about 5 mm from a raw natural stone and polishing the outer peripheral surface thereof to form a glossy surface 24A to form the natural stone layer 24. The urethane layer 21 and the glass fiber layers 22 and 23 formed into a curved plate are bonded to the inner peripheral surface (back surface) of the natural stone layer 24. The stone panel 2 can be satisfactorily attached to a curved surface such as a peripheral surface of a round pillar.

As shown in FIG. 3, the stone panel is formed so that the natural stone layer 34 has a substantially L-shaped cross section, and the back of the natural stone layer 34 faces the front and back surfaces and the natural stone layer 34. Alternatively, a urethane layer 31 having glass fiber layers 32, 33 and 35 formed on one side may be bonded. The stone panel 3 shown in FIG. 3 can be suitably used for a prism or a corner portion of an inner wall.

In addition, various design changes can be made within the scope of the matters described in the utility model registration claims.

[0023]

[Effect of the invention]

 According to this invention, the weight of the stone panel can be reduced. In addition, lightweight stone panels are very convenient to handle during construction and transportation, and can be applied to the wall and flooring of wooden buildings whose framework is not strong compared to reinforced buildings. it can.

Further, since the urethane layer and the natural stone layer are bonded to each other via the glass fiber layer, the respective layers are firmly adhered to each other, so that there is no possibility that the urethane layer and the natural stone layer are separated. In addition, since the impact applied from the outside can be absorbed by the urethane layer and the glass fiber layer, even if the natural stone layer is thin, there is no possibility of causing cracks or the like. Thereby, an integral and strong stone panel can be provided.

In addition, even if moisture infiltrates from the surface of the natural stone layer, the infiltrated water is blocked by the glass fiber layer interposed between the natural stone layer and the urethane layer, and the water enters the urethane layer. Since it does not penetrate into the floor, there is no danger of moisture corroding the foundation of the wall or floor to which the stone panel is attached. If the natural stone layer is formed to a thickness of about 5 mm, even if a concrete nail is driven into this stone panel, the natural stone layer will not be damaged or cracked. Can be easily attached to a wall or the like.
