DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile to be laid on a roof of a house or the like, and more particularly to a tile having a structure for stabilizing a stacked state when a large number of tiles are stacked.

[0002]

2. Description of the Related Art Roofs of various shapes have been manufactured by forming a composition obtained by mixing cement, aggregate, synthetic fiber or asbestos and water with a forming method such as papermaking, dewatering press or extrusion. Have been. The manufactured tile is usually stored or transported in a state where a plurality of tiles are stacked.

[0003]

By the way, for example, in the case of tiles having different thicknesses of the tile body depending on the location, when storing and transporting the tiles, if a large number of tiles are stacked, the stacked body is likely to be tilted and unstable. The roof tiles are likely to collapse during transportation, and the complicated work of stacking the broken roof tiles again may be required, or in the worst case, the tiles may be damaged when the stack is broken.

Therefore, a projection is provided on the back surface of the tile body, and the projection is brought into contact with the surface of the lower tile to support the upper and lower tiles so as to be parallel to each other. A roof tile has been already proposed in which the edge is held vertically on the mounting surface to prevent the collapse of the load during transportation. However, such a tile can solve the problem such as collapse of the load, but since the tip of the protrusion contacts the surface of the lower tile, the surface of the lower tile painted in a desired color can be removed. There is a problem of whitening or scratching, and when loading, lay paper between the protrusion and the lower tile surface, or remove the dirt on the tile surface after laying the tile, and Complicated work such as repairing scratches on the tile surface was forced.

Accordingly, the present invention has been made in view of the above-mentioned various problems of the conventional tile, and even when a large number of tiles are stacked, the stacked body is hardly inclined or collapsed. It is another object of the present invention to provide a tile that does not stain or damage the tile surface.

[0006]

Means for Solving the Problems In order to achieve such an object, the invention according to claim 1 is characterized in that when a plurality of tiles are stacked in the vertical direction, the tiles come into contact with the surface of the lower tile, and A tile in which projections supporting the upper tile are projected from a rear surface of the tile main body so that the tile main body is arranged at regular intervals and the edges of the tile main body are aligned on a vertical line with respect to the mounting surface, The gist of the present invention is a roof tile characterized in that at least the front end surface is covered with a foamed resin film. According to the invention of claim 2, when stacking a plurality of roof tiles in the vertical direction, the roof tile is brought into contact with the surface of the lower roof tile. A tile that projects the tile body of each tile at regular intervals and a projection that supports an upper tile so that an edge of the tile body is aligned with a vertical line with respect to a mounting surface on a rear surface of the tile body; At least the tip of the projection is impregnated with a coloring agent having substantially the same color as the tile surface coating. There thermosetting resin, photocurable resin, and has a tile, characterized in that is covered with a protective film consisting of at least one material selected from inorganic reaction cured product gist.

[0007]

According to the construction of the first aspect of the present invention, when a plurality of tiles are vertically stacked, the upper and lower tiles are spaced apart by a predetermined distance by the projection, and the edges thereof are vertically aligned with the mounting surface. Supported side by side. Moreover, the projections are supported on the lower tile surface via the foamed resin film, and do not directly contact the lower tile surface.

On the other hand, according to the configuration of the second aspect of the invention, when a plurality of tiles are vertically stacked, the upper and lower tiles are spaced apart by a predetermined distance by the projection, and the edges thereof are perpendicular to the mounting surface. It is supported to line up on a line. Further, the protrusion is supported on the lower tile surface via the protective film, and does not directly contact the lower tile surface.

[0009] Even if the protective film is damaged, the colorant permeable layer comes into contact with the tile surface.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings showing the embodiments. As shown in FIG. 1, the roof tile 1 has a large number of projections (also referred to as “stack projections”) 3 protruding from the back surface of the roof tile body 2. The roof tiles 1 can be stacked at regular intervals vertically so that their edges 11 are aligned on a vertical line with respect to the mounting surface 8.

[0011] Therefore, it is stable in the stacked state, and does not lose its load during transportation. Further, as shown in FIG.
Is covered with the foamed resin film 4, and when a large number of tiles 1 are stacked and transported as shown in FIG. 2, the foamed resin film 4 makes the protrusions 3 of the upper tile 1 and the surface of the lower tile 1 contact each other. The surface of the lower tile 1 must be in contact with the protrusion 3 of the upper tile 1 so as not to make direct contact.
Is not damaged or stained.

The resin forming the foamed resin film 4 is not particularly limited, but includes a urethane resin, a styrene resin, and the like.
It is preferably about 00 μm. In addition, as shown in FIG. 4, the roof tile 1 has a colorant permeable layer 5 formed on the surface layer of the projection 3 itself.
A structure in which the surface of the coloring agent penetrating layer 5 is covered with the protective film 6 may be used.

The colorant permeable layer 5 is not particularly limited,
After the tile body 2 is formed, it can be formed by impregnating from the surface of the projections 3 a solution obtained by dispersing and mixing a colorant having substantially the same color as the coating on the surface of the tile 1 in a solvent.
It is preferably about 000 μm. Although not particularly limited, examples of the colorant include carbon-based and iron oxide-based pigments, and the solvent is required to have high permeability to the roof tile body 2; Organic solvents such as acetone and toluene are exemplified.

The thickness of the protective film 6 is not particularly limited, but is preferably 30 to 200 μm (particularly preferably 50 to 100 μm).
μm) is preferred. In this way, a large number of tiles 1
2, the protective film 6 prevents the protrusion 3 of the upper tile 1 from directly contacting the surface of the lower tile 1 so that the surface of the lower tile 1 is The projections 3 do not damage or become white.

Even if the protective film 6 is damaged, the colorant penetrating layer 5 hits the surface of the lower tile 1 and the tile surface is not stained white. Examples of the material for forming the protective film 6 include a thermosetting resin, a photocurable resin, and an inorganic reaction cured product. For example, as the heat or photocurable resin, a protrusion in a fluid state at the time of application or before curing is used. 3 is required to have appropriate permeability, good adhesion to the tile body material, high tensile strength after curing, and good coating workability and curing workability. Resins of urethane type, urethane type, epoxy type, polyester type or silicone type are preferably used.

When photocurability is imparted, a photopolymerization initiator such as benzoin or azo, a polymerization accelerator such as tertiary amine, or a curing catalyst such as t-butyl peracetate is used. Is appropriately used. On the other hand, as the inorganic reaction curable composition, for example, a glass composition by a sol-gel method or the like is suitably used.
