Description

  The present invention relates to a tile panel used as an interior / exterior material for a structure such as a tunnel or a building, and more particularly to a curved tile panel suitably applied to a curved casing wall surface.

  Conventionally, tiles have been directly pasted and finished on the exterior wall of a building, the interior surface of a tunnel such as a tunnel expressway or a main national highway for the purpose of making the appearance beautiful. This direct attachment work of tiles is not easy to work because it requires the process of manually attaching the tiles to the wall of the frame using an adhesive, and requires a temperature curing suitable for adhesive curing in the winter, and condensation in the summer. There was a problem that it depends on the working environment, such as drying work required as a countermeasure.

  Therefore, in order to avoid the trouble of directly sticking the tiles one by one to the wall surface of the frame and to reduce the work at the site, a plurality of tiles are pasted in advance on a predetermined substrate such as a cement board with an adhesive or the like. Tile panels are known (see Patent Document 1, Patent Document 2, and Patent Document 3). This tile panel is manufactured in advance at a factory and pasted on the wall surface at the construction site. Quality control is easy and construction, repair, and replacement on the wall surface of a tunnel or other body are also short. There are advantages such as being able to do it in time.

  A tile panel is obtained by adhering a plurality of porcelain tiles on a substrate in advance at a factory or the like with an adhesive and applying a glaze to the porcelain tile surface to improve the reflectance. Many are used. As tile panels, tile panels of hard calcium silicate plate system, extrusion-molded cement plate system, and glass fiber reinforced cement plate system are known depending on the nature or type of the substrate. These tile panels are strong against bending fracture but very heavy. Therefore, a large amount of labor is required for the operation of attaching the tile panels to the lower ground at the construction site, and there is a problem in work efficiency.

  In addition, when a tile panel is affixed to a ground surface with a curved surface shape, such as an inner wall of a tunnel, even if the bending fracture load is large, the tile itself is a rigid body. It is difficult. As a method of attaching the tile panel to the curved casing surface, it is possible to form the tile panel according to the curvature of the ground surface in advance at the molding stage, or to mold with a small tile panel size according to the curvature of the casing surface. Conceivable.

  However, in the former case, it is difficult to form a tile panel with high accuracy in accordance with the curvature of the frame surface from the viewpoint of the molding accuracy of the tile panel, and when the curvature of the frame surface is different for each tunnel like a tunnel wall surface. However, since a separate tile panel has to be produced each time, there is a problem that the production cost is remarkably increased. In the latter case, since the number of tile panels used is increased, there is a problem that production costs and construction costs for tile panels, and further, man-hours are increased, resulting in poor economic efficiency and workability.

Therefore, as a tile panel that can be attached along such a curved tile attachment surface, an adhesive material having flexibility at room temperature even after curing is used as a joint material, and only a plurality of joint materials are used. There has been proposed a tile panel in which tiles are connected and formed into a desired size (see Patent Document 4). However, this tile panel is made to correspond to a curved surface through a joint material, and does not give the tile itself a function along the curved surface. As a result, the tile panel is rather similar to a directly attached tile construction.

  As described above, in the conventional tile panel, there is a problem in work efficiency due to the large weight as well as a problem in attaching to the curved wall surface of the curved shape.

  Accordingly, an object of the present invention is to provide a lightweight tile panel that can be attached along a wall surface of a curved tile-attached housing.

  When the joint width between tiles is set to 2 to 5 mm as usual, the tile panel itself may be a rigid body and a predetermined curvature may not be obtained. Increasing the joint width between tiles makes it easier to bend, but this reduces the actual area of the tile surface and does not serve as an interior or exterior. Another object of the present invention is to provide a tile panel that can be suitably attached to a curved wall surface of a curved surface even when the joint width between tiles is narrow.

  In order to achieve the above object, a curved tile panel of the present invention is obtained by attaching a tile having a cross-sectional defect portion with a reduced thickness to at least one side of the back surface facing the flexible substrate. This is a curved tile panel.

The curved tile panel of the present invention has the following preferred modes.
(a) The tile panel as described above, wherein the tile is provided with a cross-sectional defect portion on a side perpendicular to the body curved surface.
(b) The above-described curved tile panel in which the defect width w in the tile width direction of the cross-sectional defect portion is 10 to 30% of the tile width W.
(c) The curved tile panel according to the above, wherein the thickness d of the cross-sectional defect portion in the tile thickness direction is 10 to 30% of the tile thickness D.

  The curved tile panel of the present invention can be used as an interior / exterior material by being attached to a wall surface of a cabinet to construct a structure such as a building or a tunnel.

  In the curved tile panel of the present invention, a flexible substrate is used as the substrate, and the tile having the cross-sectional defect portion as described above is used on the side facing the flexible substrate. It is possible to install it neatly along, and even if the joint width between the tiles is as small as 2 to 5 mm, for example, it can be attached beautifully.

  ADVANTAGE OF THE INVENTION According to this invention, the tile panel which can be attached along the wall surface of a tile attachment housing | casing which is lightweight and curved shape is obtained. Moreover, according to this invention, even if the joint width between tiles is narrow, the lightweight tile panel which can be suitably affixed on the curved-shaped housing | casing wall surface is obtained.

  First, an exemplary embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view for illustrating the curved tile panel of the present invention. FIG. 5 is a schematic perspective view illustrating the curved tile panel of the present invention.

  1 and 5, a curved tile panel 1 has a plurality of tiles 3 bonded on a flexible substrate 2 with an adhesive 4. The tiles 3 are arranged with joints 5 having appropriate intervals between other tiles 3 adjacent to each other, and the width of the joints 5 varies depending on the size and use of the tiles 3. The joint width when applied to is about 2 to 5 mm.

  In FIG. 1, the tile 3 is formed with a cross-sectional defect portion 6 having a reduced thickness on at least one side portion on the back surface side facing the flexible substrate 2. The cross-sectional defect portion 6 of the tile 3 used in the present invention is preferably provided on a side portion on the side where the tile 3 is orthogonal to the body curved surface (not shown). In FIG. 1, the cross-sectional defect portion 6 is formed in two opposite side portions on the upper side and the lower side of the tile 3, but the tile in which the cross-sectional defect portion 6 is formed only in one side portion due to the curved shape to be attached. 3 may be sufficient.

  FIG. 2 is a cross-sectional view showing a state where the curved tile panel 1 of FIG. 1 is bent along a curved body surface (not shown), and is understood as a state when the curved tile panel 1 is attached to the curved body. In the present invention, the tile panel 1 is attached to the tile 3 by using the flexible substrate 2 having a large flexural modulus for the substrate and providing the cut-out cross-sectional defect portion 6 having a reduced thickness on the back surface side of the tile 3. It can be naturally curved to the side and can be attached to the wall surface of the housing without increasing the joint width. Although the joint width becomes smaller by curving the curved tile panel 1, the joint width can be adjusted in anticipation of the tile 3 when the tile 3 is pasted depending on the degree of curvature. Thus, the shape and joint width of the cross-sectional defect part 6 can be appropriately adjusted according to the curved surface shape.

  Next, the cross-sectional defect portion 6 will be described in more detail. FIG. 3 is a partially enlarged view of FIG. 1 showing one embodiment of the curved tile panel of the present invention. In the aspect of FIG. 3, the cross-sectional defect | deletion part 6 is formed in the shape which penetrated and was cut off by the rectangular parallelepiped shape on each back side of the upper side part of tile 3, and a lower side part. In this case, the upper side and the lower side of the tile 3 correspond to sides on the side where the tile 3 is orthogonal to the body curved surface.

  In the cross-sectional defect part 6 shown in FIG. 3, the defect width w in the tile width direction of the cross-sectional defect part 6 is preferably 10 to 30%, more preferably 15 to 25% of the tile width W. In addition, the thickness d of the cross-sectional defect portion 6 in the tile thickness direction is preferably 10 to 30% of the tile thickness D, and more preferably 15 to 25%. If the defect width w and the thickness d are too small, it is difficult to bend along the curved surface of the casing, and if the defect width w and the thickness d are too large, the adhesion area of the tile 3 to the flexible substrate 2 becomes too small. Thus, sufficient holding of the tile 3 cannot be expected.

  Although the cross-sectional defect | deletion part 6 is formed in the shape cut off by the rectangular parallelepiped shape in FIG. 3, the shape cut off by the cube shape may be sufficient. FIG. 4 is a cross-sectional view illustrating various tiles used in the present invention.

  4A shows the above-described tile in which the cross-sectional defect portion is formed only on one side of the tile 3. Further, (b) is formed in a shape in which a cross-sectional defect portion is cut through a triangular pyramid with a taper on two opposite side portions on the upper side and the lower side of the tile. Further, in (c), the cross-sectional defect part is formed in a shape that is cut out with a curve on the two sides of the tile. FIG. 3D shows the tile 3 shown in FIG. 3 in which the cross-sectional defect portion is formed in a shape in which the end of the cross-sectional defect portion is cut off with a curve.

  In the present invention, the cross-sectional defect portion 6 has a shape in which a rectangular parallelepiped shape (or cubic shape) as shown in FIG. 3 is cut out, or a shape in which a terminal end is cut out with a curve as shown in FIG. Those are preferred. These shapes are advantageous in terms of ease of fabrication.

  The curved tile panel according to the present invention is a tile panel formed by attaching a tile to a substrate. The flexible substrate is used as a substrate, and the thickness of the tile is reduced to at least one side of the back surface facing the flexible substrate as a tile. A tile having a cross-sectional defect portion is used.

  As the tile used in the present invention, a porcelain tile is representative, and a glaze is applied to the surface of the porcelain tile to improve the reflectance. Among them, examples of the tunnel use include a double-clad tile (60 mm × 227 mm) and a 100 mm × 200 mm tile.

  The size of the tile varies depending on the application, but a tile having a side of about 45 mm to 200 mm and a thickness of about 9 mm to 12 mm is usually used.

  Moreover, as a flexible substrate used by this invention, a steel plate with high corrosion resistance, a high quality calcium silicate board, etc. are mentioned. The steel plate is preferably plated with zinc or the like, and the thickness is usually about 0.6 mm to 1.6 mm. The high-quality calcium silicate plate having a thickness of about 4 mm to 6 mm is used.

In the present invention, a flexible substrate is used as the substrate. For this purpose, a flexible substrate having a flexural modulus of 3.0 × 10 ⁶ kgf / cm ^{2 to} 1.0 × 10 ⁵ kgf / cm ² is suitable. A flexible substrate having a size of 5 × 10 ⁶ kgf / cm ^{2 to} 1.5 × 10 ⁵ kgf / cm ² is preferably used. The flexural modulus can be measured by the “metal material bending test method” (JIS Z 2248).

In the present invention, a tile having a cross-sectional defect portion is attached to a flexible substrate with an adhesive or the like. The type of adhesive, the coating amount, etc. are appropriately selected according to the tile to be used and the substrate. Usually, a plurality of tiles are attached to a flexible substrate with an appropriate joint width. The number of tiles to be attached is arbitrary, and may be 30 to 200 / m ^2. For example, in the case of the above-mentioned two-tile tile for a tunnel, it is preferably about 60 to 80 / m ² and 100 mm. In the case of a × 200 mm tile, the number is preferably about 40 to 60 sheets / m ² .

  The tile is attached to the flexible substrate with an appropriate joint width. Since the curved tile panel of the present invention is curved according to the curved surface of the casing, the tiles may come into contact with each other and fall off if the joint width is too small. On the other hand, if the joint width is too large, the actual area of the tile surface will be reduced and it will not serve as an interior or exterior. In the present invention, the joint width of the tile can be effectively applied in the range of 2 mm to 5 mm.

Next, the case where the curved tile panel of the present invention is attached to the tunnel wall surface will be described. The body curved surface at the top of the main highway tunnel usually has a radius of curvature r of about 500 cm. With respect to this curved body surface, a cross-sectional defect portion is formed on a flexible substrate (high corrosion resistance galvanized steel sheet, flexural modulus: 2.1 × 10 ⁶ kgf / cm ² ) of width 640 mm × length 1,556 mm as shown in FIG. A curved tile panel in which the provided 100 mm × 200 mm porcelain tile is pasted with an adhesive with a joint width of 4 mm is attached. The attachment is provided with attachment holes at the end in the width direction of the flexible substrate, and the curved tile panel is fixed using stainless steel bolts.

  Since the curved tile panel of the present invention can be affixed along the curved casing wall surface, a curved structure such as a tunnel or a building can be beautifully decorated with a natural feeling. Thus, the curved tile panel of the present invention has a great industrial applicability for use as an interior / exterior material for various structures.

FIG. 2 is a cross-sectional view showing a state where the curved tile panel of FIG. 1 is bent along the curved surface. FIG. 3 is a partially enlarged view of FIG. FIG. 4 is a cross-sectional view illustrating various tiles used in the present invention. FIG. 5 is a schematic perspective view illustrating a curved tile panel of the present invention.
