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 in which water is mixed 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 becomes unstable and tilts, or collapses during transportation. There was a problem that they tended to.
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, Japanese Patent Application No. 2-46107, which is not yet known, has a protrusion formed on the back surface of the roof tile.
A roof tile that can stabilize the stacked state by it is proposed. 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, since the lower end of the protrusion contacts the surface of the lower roof tile, there is a problem that the surface of the lower roof tile is soiled or damaged. Therefore, when stacking, complicated work such as laying paper between the protrusion and the surface of the lower tile, removing dirt on the tile surface after roofing the tile, and repairing scratches on the tile surface Was being forced.

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

[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 the lower end surface of the protrusion is coated with a heat or light curable resin or an inorganic reaction curable composition to provide a cured layer.

In the above expression, the lower end of the protrusion for forming the virtual plane means the lower end of the protrusion covered with the hardened layer.

The heat- or photo-curable resin is applied in a liquid or powder form so as to cover at least the lower end surface of the protrusion by a roll, a brush or a spray, and uses light or heat or energy of both of them. Is cured. Such a heat- or light-curable resin has appropriate permeability to the base material forming the protrusions during application or in a fluidized state before curing, and has good adhesiveness with the base material, High tensile strength after curing and good coating workability and curing workability are required, and epoxy-based, polyester-based, or silicon-based resins are preferably used.

Further, in the case of imparting photocurability, a benzoin-based or azo-based photopolymerization initiator, a polymerization accelerator such as a tertiary amine, or a curing catalyst such as t-butyl peracetate is appropriately used. To be

Further, as the inorganic reaction curable composition, for example, a glass composition by a sol-gel method or the like is preferably used.

[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.

In addition, since the hardened layer is provided at the lower end of the protrusion that contacts the lower roof tile so as to at least cover the lower end surface, stains and scratches on the roof tile surface due to the contact of the protrusion are effectively prevented. It

[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, the hardened layer portion is shown in a sectional view in order to clarify the hardened layer.

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. Virtual tile i formed by connecting the roof tile 1 with the floor surface G or the lower end contact portion 3a of the ridge side 3 in contact with the lower roof tile 1
And another roof tile 1 adjacent above or below this one roof tile
The lower end 11a of the projection 11 provided on the roof and the other roof tile 1 and the lower edge contact portion 3a of the ridge side 3 that is in contact with the one roof tile are substantially parallel to the virtual plane i formed. , Position and size. Therefore, as shown in FIG.
When a large number of tiles are stacked, the surface of each roof tile 1 ... Is always parallel to the floor surface G. That is, the stacked state is stabilized.

Further, a hardened layer 12 is provided on the surface of the protrusion 11. The hardened layer 12 is formed by applying an acrylic thermosetting resin liquid in this embodiment. Therefore, roof tile 1
When a large number of stacked tiles are provided, the hardened layer 12 is provided on the surface of the protrusion 11 and the hardened layer 12 comes into contact with the surface of the roof tile 1 located below, so that the surface of the roof tile 1 becomes dirty, There is no damage.

The hardened layer 12 does not necessarily have to be provided on the entire surface of the protrusion 11 and may be formed so as to cover at least the surface of the lower end 11a of the protrusion 11.

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

When the roof is to be roofed with the tile 1, one tile 1 is arranged at the lower left, and a nail is inserted into the nail hole 4 formed in the tile main body 2 of the tile 1 and fixed to the base plate 20. After that, 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 6R of the other roof tile 1
The convex portion 10 formed on the side of 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 edge and the left and right side edges. 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 examples, the cured layer 12 was formed using the acrylic thermosetting resin liquid, but by applying other thermosetting resin or photocurable resin, or inorganic reaction curable composition A hardened layer may be formed, and the same effect can be obtained.

〔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 heat or photo-curable resin or the inorganic reaction curable composition is applied to the surface of the protrusions to form the cured layer, even if a plurality of roof tiles are stacked as described above, the roof tile surface becomes dirty. It does not get scratched or damaged.
