Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural or stone material such as slate, granite or marble, which is formed into a plate or tile of a predetermined size or size, and is used as a building material such as a floor member or a wall member. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural stone tile used and reinforced on its back side, and a method for manufacturing the same.

[0002]

2. Description of the Related Art Natural stone has a solid feeling and luxury.
It is widely used as floor members and wall members in offices or buildings. However, there is a problem in that the natural stone material itself is expensive, has a considerable weight, requires handling and transportation, and requires much time and labor in construction.

[0003] Therefore, in order to reduce the weight and cost by processing a natural stone material into a relatively thin tile shape, and to maintain a predetermined strength, a so-called aluminum-made honeycomb structure is adhered on the back surface side, that is, a so-called tile. Reinforced natural stone tiles have emerged.

[0004]

However, since natural stone and aluminum have different linear expansion coefficients, the natural stone has a reinforcing function due to peeling over time or a crack in the natural stone. There is a problem that it is substantially lost. In addition, in order to eliminate the difference in the coefficient of linear expansion, it is necessary to devise measures such as interposing an absorbing member such as a sheet between the natural stone material and the honeycomb structure made of aluminum, so that the inconvenience is not easy. There is also a problem that the cost increases.

[0005] Therefore, the conventional reinforced natural stone tiles have problems that must be solved to reduce the cost and weight and to sufficiently fulfill the reinforcing function.

[0006]

According to the present invention, as a specific means for solving the problems of the prior art, a honeycomb structure made of ceramics is integrally formed on the back surface of a natural stone formed in a predetermined shape and thickness. After a honeycomb structure made of ceramics is integrally attached to both front and back surfaces of a reinforced natural stone tile characterized by being stuck and a natural stone formed in a predetermined shape and thickness, The present invention provides a method for manufacturing a reinforced natural stone tile, characterized in that a center part is cut in a thickness direction of the stone and the stone is divided into two parts.

Further, the present invention includes an additional component that the linear expansion coefficient of the natural stone tile and the linear expansion coefficient of the honeycomb structure are substantially the same.

The reinforced natural stone tile according to the present invention has a honeycomb structure made of ceramics integrally adhered to the back surface of the natural stone, and both have substantially the same coefficient of linear expansion. Even after long-term use, there is no separation between the two or the natural stone material is cracked over time, so that sufficient reinforcement is maintained.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the illustrated embodiments. In the first embodiment shown in FIGS. 1 and 2, the reinforced natural stone tile 1 is formed by forming a natural stone 2 made of, for example, granite into a rectangle having a predetermined thickness and a rectangle or a square. The honeycomb structure 3 made of ceramics is integrally adhered to the back surface of the substrate with a predetermined adhesive.

In the first embodiment, the natural stone 2 is a rectangle such as a square or a rectangle having a side length of about 250 mm and a thickness of about 7 mm.
These dimensions vary depending on the conditions of the place where they are used or the design, and the length of one side is 100 to 500 m.
m and the thickness thereof can be appropriately selected in the range of 3 to 15 mm.

The honeycomb structure 3 attached to the back side of the natural stone 2 has substantially the same length of each side constituting the hexagonal space 3a, and has a porosity of substantially 80%. As described above, the bonding area with the natural stone 2 is about 20% or less, but there is no problem in strength in the bonding and reinforcement.

FIGS. 3A, 3B and 3C show another structure of the honeycomb structure 3 formed of ceramics. FIG. 1A shows an elongated honeycomb structure in which the hexagonal space 3a is widened, and the porosity is about 90%.

FIG. 2B shows a honeycomb structure 3 in which the shape of a space portion is changed, and is a triangular space portion 3b. The triangular spaces 3b are arranged in a plurality of rows alternately in different directions, and have a porosity of about 90%. A reinforcing plate 4 is provided along a portion corresponding to the edge of the natural stone 2 so that the edge is sufficiently reinforced.

Further, FIG. (C) shows a honeycomb structure 3 in which a plurality of rows of teardrop-shaped spaces 3c are alternately changed in direction as spaces of the honeycomb structure 3.
In this case, the porosity is about 70% or more, and the bonding area with the natural stone 2 is increased, so that the strength is further enhanced.

In any of the embodiments, it is possible to use a honeycomb structure 3 having a porosity of 70 to 90% in a space portion, and a total height (thickness) of 20 to 90%.
A 70 mm one can be used.

FIG. 4 shows an example of the production of the reinforced natural stone tile 1 according to the present invention. First, the natural stone 2 is formed to have a thickness (in consideration of a cutting allowance) of about twice or more the thickness expected as the reinforced natural stone tile 1,
The honeycomb structure 3 is attached to both side surfaces thereof.

Next, the natural stone material 2 having the honeycomb structure 3 adhered to both sides is placed on a predetermined cutting device 5 and pressed and supported by the pressing support members 6 from both sides. By cutting the central portion of the natural stone 2 according to 7, two reinforced natural stone tiles 1 can be formed simultaneously.

This manufacturing method is particularly effective when a relatively thin natural stone 2 is used as the reinforced natural stone tile 1. For example, when a relatively thin natural stone material 2 having a thickness of about 3 mm is used in a case where it is used as a wall material, the material may be damaged depending on the handling, and the material is wasted. In such a case, for example, by forming the natural stone 2 to a thickness of 7 mm in advance, breakage is avoided, and after the honeycomb structure 3 is attached to both sides, cutting is performed from the center of the natural stone 2 ( Cutting allowance 1m
m) results in a 3 mm thick stone.
Of course, the same applies to the case where a relatively thick natural stone is used.

In any case, the reinforced natural stone tile according to the present invention basically has a honeycomb structure formed of ceramics having substantially the same coefficient of linear expansion as natural stone on its back surface, and In addition to increasing the strength of the stone material, it is possible to reduce the weight of the whole, and at the time of construction, since the back side is a honeycomb structure, for example, a mortar for mounting is part of the honeycomb structure. And increase the strength of the installation.

[0020]

As described above, in the reinforced natural stone tile according to the present invention, a honeycomb structure made of ceramics is integrally adhered to the back surface of a natural stone formed in a predetermined shape and thickness. With this configuration, the natural stone material and the honeycomb structure have substantially the same linear expansion coefficient, so that they follow the same temperature change at an external temperature, and peeling occurs between them over time. Also, since there is no crack on the natural stone side, a sufficient effect is obtained that sufficient reinforcement is maintained even after long-term use.

Further, the method for producing a reinforced natural stone tile according to the present invention is characterized in that a honeycomb structure made of ceramics is integrally attached to both front and back surfaces of a natural stone formed in a predetermined shape and thickness. By cutting the central part in the thickness direction of the natural stone material and dividing it into two, even if the natural stone material is formed relatively thin, it is already reinforced in the handling in the manufacturing process. It has an excellent effect that breakage of itself can be largely eliminated.

Further, the reinforced natural stone tiles can be provided at a low cost as a whole while exhibiting luxuriousness, profound feeling and calmness in appearance, and the weight of the whole is reduced in handling during transportation or construction. Therefore, an excellent effect that workability is remarkably improved is obtained.
