Description

Description: [Industrial field of application] The present invention relates to a roof tile for a roof of a house or the like, and particularly,
The present invention relates to a roof tile provided with a structure for stabilizing a stacked state when a large number of roof tiles are stacked.

[Conventional technology]

BACKGROUND ART Conventionally, roof tiles of various shapes have been manufactured by molding a composition obtained by mixing water with cement, aggregate, synthetic fiber, asbestos or the like by a molding method such as papermaking, dewatering press or extrusion. The manufactured roof tiles are usually stored or transported in a state where a plurality of roof tiles are stacked.

[Problems to be Solved by the Invention]

When storing and transporting roof tiles, if a large number of roof tiles are stacked, depending on the shape of the roof tile, for example, if the roof tile has a different thickness depending on the location, the stack may become unstable and may not be transported. There was a problem that it tended to collapse. Therefore, the troublesome work of stacking the collapsed roof tiles again is forced, and the accident occurs that the roof tiles are damaged when the stacked body collapses in the case of bare-footing.

In order to solve the above problems, a roof tile may be considered in which a protrusion is formed on the back surface of the roof tile to stabilize the stacked state. That is, the projections formed on the back surface keep the surfaces of the stacked roof tiles parallel to each other, thereby stabilizing the stacked state and preventing accidents such as collapse during transportation. .

However, in this roof tile, since the lower end of the projection contacts the surface of the lower roof tile, the surface of the lower roof tile may be stained white. Complicated work such as laying paper in between, wiping dirt off the roof tile after the roof is installed, and repairing scratches on the roof tile are required.

Therefore, the present invention has been made in view of various problems of roof tiles as described above, and even if a large number of roof tiles are stacked,
It is an object of the present invention to provide a roof tile in which the laminated body is unlikely to tilt or collapse and which does not stain the roof tile surface.

[Means for solving the problem]

In the roof tile of the present invention, at least one protrusion is provided on the back surface edge along one side of the roof tile body. This projection is a virtual plane formed by connecting the lower end of the projection provided on one roof tile and the lower edge contact portion of the lowermost side of the other roof tiles. Formed by connecting the lower ends of the protrusions provided on the other roof tiles stacked above and below the one roof tile and the lower edge contact portions of the side walls located at the lowermost of the other side walls of the other roof tile. Is formed so as to be substantially parallel to the virtual plane. Then, at least on the lower end portion of the protrusion, a colorant permeation layer in which a colorant having substantially the same color as the roof tile surface is permeated is formed so as to reach a predetermined depth from the lower end surface.

The colorant permeation layer is formed in substantially the same color as the roof tile main body surface so that when the roof tiles of the present invention are stacked, the protrusions do not stain white when contacting the lower roof tile main body surface. . That is, when paint is applied to the surface of the roof tile body, a colorant having substantially the same color as the paint on the surface of the roof tile body is used. A colorant having a color substantially the same as the color is penetrated to reach a predetermined depth from the lower end surface at least at the lower end portion of the protrusion to form a colorant permeation layer.

The colorant permeation layer is formed by, for example, dissolving a colorant such as a pigment in a solvent and allowing the colorant to permeate from the surface of the protrusion by a roll, a brush, a spray or the like. As the colorant to be used, for example, a carbon-based or iron oxide-based pigment is preferably used, and on the other hand, the solvent is required to have high permeability to the roof tile main body substrate, and therefore water is usually used. However, an organic solvent such as toluene or other thinner may be appropriately used.

The depth of the colorant permeation layer formed, that is, the predetermined depth in the above expression, means that the colorant permeation layer of the protrusions contacting the roof tile main surface below when the roof tiles of the present invention are stacked, The depth is sufficient to function so as not to stain the surface of the lower roof tile body white and is uniquely determined because it varies depending on the material of the roof tile body used and the shape of the roof tile and the protrusions. is not.

[Action]

When a plurality of roof tiles of the present invention are stacked, the protrusions are provided as described above, and thus the surfaces of the stacked roof tiles are parallel to each other. Therefore, the stacked state of the plurality of roof tiles is effectively stabilized.

Further, since the above-mentioned colorant permeation layer is formed on at least the lower end portion of the protrusion that contacts the lower tile, even if the protrusion contacts the lower tile main body surface, No stain of a color different from the color of the roof tile body surface will occur.

[Explanation of Example]

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
It should be noted that, in FIGS. 2 to 4 of the accompanying drawings, in order to clarify the colorant permeation layer, the adhesive agent permeation layer portion is shown in a sectional view.

FIG. 1 is a perspective view showing a roof tile according to an embodiment of the present invention. In the roof tile 1, a plurality of nail holes 4 are formed penetrating from the front surface side to the back surface side at appropriate intervals at an edge portion of the roof tile main body 2 having a substantially flat plate shape along the ridge side 3.

Further, a surface trapezoidal portion 6H that is slightly lower than the surface 2a of the roof tile body 2 is formed at the surface edge portion along the right side 5 of the roof tile body 2. On the other hand, a back surface trapezoidal portion 6R slightly higher than the back surface of the roof tile body 2 is formed at the back surface edge portion along the left side 7. The front surface trapezoidal portion 6H and the back surface trapezoidal portion 6R are formed so as to be located on the same plane. A running water passage 9 extending from the ridge side 3 to the eaves side 8 is formed on the side of the front trapezoidal portion 6H, and on the other hand, corresponds to the running water passage 9 on the back trapezoidal portion 6R side. The convex portion 10 having a shape is formed so as to have a sectional shape that bulges downward.

In addition, the roof tile body 2 has a thickness on the ridge side 3 side that is the eave side 8
It is formed to be slightly larger than the side thickness, and a plurality of protrusions 11 are provided on the back surface edge portion along the eaves side 8 of the roof tile body 2 according to the difference in these thicknesses.

The protrusion 11 is formed in a position and a size that satisfy the following relationship. That is, as understood by referring to FIG. 2 and FIG. 4, when a plurality of roof tiles 1 are stacked, the projections 11 and the lower ends 11a of the projections 11 provided on one roof tile 1 are the same as those of the roof tile 1. Of the roof tile 1 and the lower edge contact portion 3a of the ridge side 3 which is in contact with the floor surface G or the lower roof tile 1, and a virtual plane i formed above and below the one roof tile. The lower end 11a of the protrusion 11 provided on the roof tile 1 and the virtual plane i formed by connecting the other roof tile 1 to the lower edge contact portion 3a of the ridge side 3 which is in contact with the one roof tile are substantially parallel to each other. The position and size are as follows. Therefore, as shown in FIG. 2, when many roof tiles 1 are stacked, the surface of each roof tile 1 and the floor surface G are always parallel to each other. That is, the stacked state is stabilized.

Further, a surface paint layer (not shown) is provided on the surface 2a of the roof tile body 2 of the roof tile 1 of this embodiment. This surface paint layer is formed by applying a paint containing an acrylic resin as a main component. A colorant permeation layer 12 is formed on the surface of the protrusion 11. In the present embodiment, the colorant permeation layer 12 is formed by permeating an aqueous solution of an iron oxide-based pigment dissolved in water from the surface of the protrusions 11, whereby the surface of the protrusions 11 is formed into the roof tile body 1. Is colored in the same color as the surface paint layer on the surface 2a. Therefore, when a large number of roof tiles 1 are stacked, the colorant permeation layer 12 is formed on the surface of the protrusion 11 and the roof tile 1 with the colorant permeation layer 12 positioned below is formed.
Since it comes into contact with the surface 2a of the roof tile body 2, the surface 2a of the roof tile body 2 does not become white.

The state in which the roof tile 1 of the above embodiment is installed will be described with reference to FIG.

When roofing with a tile 1, one tile 1 is arranged at the lower left, and a nail is inserted into a nail hole 4 formed in the tile main body 2 of the tile 1,
Fix to the base plate 20. Thereafter, the back surface trapezoidal portion 6R of the other roof tile 1 arranged on the right side is placed on the front surface trapezoidal portion 6H of the one roof tile 1 and is formed on the side of the front trapezoidal portion 6H of the one roof tile 1. In the running water passage 9, the back surface trapezoidal portion of the other roof tile 1
The convex portion 10 formed on the side of 6R is fitted. In this state, the roof tiles 1 and the roof tiles 1 are substantially flush with each other. After that, the nail is inserted into the nail hole 4 formed in the roof tile body 2 of the other adjacent roof tile 1 and fixed to the base plate 20.

Further, the other roof tile 1 arranged above and adjacent to the one roof tile 1 has its projection 11 engaged with the ridge side edge 3 of the one roof tile, and the back surface edge portion along the eave side edge 8 is described above. After arranging the roof tile 1 so as to cover the nail fixing the roof tile 1, the other roof tile 1 is similarly fixed by inserting the nail into the nail hole formed in the roof tile main body 2. In this case, the protrusion 11 formed on the back surface of the roof tile main body 2 on the upper adjacent side takes into account the overlap margin with the first roof tile 1 arranged on the lower adjacent side, and the ridge side 3 of the single roof tile 1 is taken into consideration. It is provided at a position where it does not ride on the surface edge along the.

As described above, new roof tiles are sequentially arranged while partially overlapping the roof tiles arranged on the left side and the bottom side.

In addition, in the said Example, in the roof tile of the plate shape with different eaves side 8 and ridge side 3, the protrusions 11 and 11 provided on the back edge of the eaves side 8 are shown. However, depending on the position where the roof tile has a large thickness, protrusions may be provided on the back surface edge portions of other side edges such as the ridge side and the left and right sides. However, in the above embodiment, since the protrusion 11 is provided on the edge of the eaves side 8, when the roof tile is roofed, the protrusion will engage with the ridge side of the next adjacent roof tile. There is an advantage that problems such as falling of roof tiles in the roofing state can be solved.

Further, the number of the protrusions is arbitrary, and the planar shape of the protrusions is not limited to that shown in the figure, and may be formed to have a constant length such as a rib shape.

Furthermore, the shape is not limited to the flat roof tile as described above, but may be unstable when placed on the floor surface, for example, a roof tile with a convex portion formed on a part of the back surface or a curved surface as a whole. Even if the roof tiles are formed on the roof tiles so that the virtual planes formed at the lower contact portions of the roof tiles are substantially parallel to each other when stacked.
By providing one or more protrusions on the side edge,
The present invention can be applied.

In the above example, the colorant permeation layer 12 was formed using an aqueous solution of an iron oxide pigment dissolved in water.However, when the color of the roof tile main body surface is another color, naturally the roof tile main body surface Other colorants depending on the color and solvents suitable for the other colorants are used.

Further, the colorant permeation layer 12 was formed on the entire outer surface of the protrusions, but since it is usually the lower end portion that contacts the lower roof tile main body surface, the colorant permeation layer 12 is at least the protrusions. The effect of the present invention can be obtained as long as it is formed at the lower end portion.

〔The invention's effect〕

As described above, according to the present invention, the projection is formed on the back surface of the roof tile, and the projection is formed by connecting the lower end of the projection and the lower edge contact portion located at the lowermost side of the side. A plane and the lower ends of the protrusions of other roof tiles that are adjacent to the top and bottom of this roof tile,
Since the virtual plane formed by connecting the lower edge contact portion located on the lowermost side of the side is substantially parallel to each other, the surface of each roof tile in a state where a large number of roof tiles are stacked is It is always parallel, which stabilizes the stack. Therefore, it is possible to reliably prevent problems such as collapse of the stacked roof tiles during storage or during transportation.

Further, since the colorant permeation layer described above is formed at least at the lower end portion of the protrusion, even if a plurality of roof tiles are stacked as described above, the roof tile surface is not stained white.
