Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof tile. More specifically, the invention of this application relates to a roof tile excellent in appearance that can easily change the positional relationship between slit portions of upper and lower roof tiles to be loaded.

[0002]

2. Description of the Related Art Conventionally, in roofs of houses and the like,
A construction method in which roof tiles such as flat slate boards are overlapped with each other at a fixed width and then roofed is adopted. Also, a roof tile in which a slit portion is provided on an exposed surface in order to improve the appearance of the roof surface is known.

[0003]

However, in the case of conventional roof tiles, since the overlapping width of each other is constant, it is not possible to change the pattern of the roof tile. In view of this, there have been proposed roof tiles in which marks for designating the overlapping positions of the roof tiles to be loaded are provided at a plurality of locations, and the positional relationship between the slit portions of the upper and lower roof tiles can be variously changed. However, in a normal roof tile, since the surface state (pattern and fabric state) of an unexposed surface on which the roof tiles to be laminated are overlapped and an exposed surface having a slit portion are different, the lower roof tile is cut from the slit portion of the upper roof tile. Exposure of the non-exposed surface was not preferable in terms of appearance.

[0004] In the case of such a roof tile, waterproofness to a slit portion whose position is variously changed has not been particularly considered. The invention of this application has been made in view of the circumstances described above, and solves the problems of the conventional roof tiles, and facilitates the positional relationship between the slits of the upper and lower roof tiles to be loaded. It is an object of the present invention to provide a new roof tile that can be changed and that does not impair the appearance and waterproofness even when an exposed surface is exposed from a slit portion.

[0005]

The present invention solves the above-mentioned problem by providing an unexposed surface on which a roof tile to be stacked is overlapped, and an exposed surface below the unexposed surface,
The exposed surface is a roof tile with multiple slits,
On the non-exposed surface, the edge alignment mark of the roof tile to be loaded is provided at multiple places, and the surface condition of the unexposed surface and the exposed surface exposed from the slit of the roof tile to be loaded is the same or almost the same. There is provided a roof tile characterized by the following.

Further, in the roof tile according to the present invention, it is preferable that a mountain-shaped drainage portion is provided on the upper surface of the non-exposed surface, the slit-shaped cut end of the roof tile to be loaded facing the cut end. . In a preferred embodiment, the roof tile according to the present invention further includes an alignment mark at a position where １ ／ or の of the width of the roof tile to be stacked is overlapped.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

[0008]

FIG. 1 is a plan view showing an embodiment of a roof tile according to the present invention. A flat roof tile (1) is mounted on a roof tile (1L) (1R). Are illustrated in a state where 横 of the respective widths are overlapped. The roof tile (1) has a non-exposed surface (2) on which the roof tiles (1L) and (1R) to be stacked are overlapped, and an exposed surface (3) below the non-exposed surface (2). .

Drain portions (4) and (5) are formed on the upper surface and both end surfaces of the non-exposed surface (2), respectively. The non-exposed surface (2) is provided with nail holes (6) for fixing the roof tile (1) to the roof base material, and grooves are formed around these nail holes (6). A waterproofed drainer (7) is also formed. Further, alignment marks (8L) and (8R) are provided at both ends of the non-exposed surface (2) to specify the lower end positions of the roof tiles (1L) and (1R) to be loaded. In addition, alignment marks (10L) (10R) for specifying the positions of the lower end corners (9L) (9R) of the roof tiles (1L) (1R) to be loaded, and roof tiles (1L) (1R) respectively. Side edge (11L) (11
Alignment mark (12) for positioning by contacting R)
have.

Further, as shown in FIG. 2, the unexposed surface (2) has a width of 1/3 of the width of the roof tile (1L) to be loaded.
There is also provided an alignment mark for specifying a position at which two thirds of the roof tile (1R) are overlapped. That is, the lower end corner portion (9R) of the roof tile (1L) (1R)
L) (9R) alignment marks (1
Alignment mark (1) that specifies the side edge (11L) (11R) position of 3L) (13R) and roof tile (1L) (1R)
4) is provided. Also, as exemplified in FIG.
A similar alignment mark (15L) (15) for overlapping 2/3 of the roof tile (1L) and 1/3 of the roof tile (1R)
R) (16).

Each of these alignment marks may be formed with a notch groove, or may be formed by engraving with a paint or the like. Alternatively, the entire non-exposed surface (2) may be a concave surface, and each mark may be raised in a convex shape. On the other hand, on the exposed surface (3), two slit portions (17) are formed at equal intervals from both ends.
In addition, both ends of the exposed surface (3) have notches (18) that are approximately half the shape of the slits (17), and the notches (18) of the adjacent roof tile (1) are joined. Thus, the same gap as the slit portion (17) is formed. Further, on the exposed surface (3), when a half of the width of the roof tile (1) to be loaded is overlapped, a cutting mark (19) for specifying a position to be trimmed as an edge of the roof surface, There is also provided a cutting mark (20) when one third of the width is overlapped.

In the roof tile (1) according to the present invention, the slit portion (1) of the roof tile (1L) (1R) to be loaded is provided.
The surface condition of the non-exposed surface (2) exposed from 7) is the same as the exposed surface (3). For this reason, a roof surface with good appearance can be configured. Exposed surface (3)
Is usually coated to improve weather resistance, appearance color tone, pattern, etc., but the portion of the non-exposed surface (2) exposed from the slit portion (17) is exposed to such exposure. The surface state of the surface (3), that is, the same as the surface pattern or the fabric state by painting, or a similar state similar to this without any discomfort in appearance is prepared. For example, specifically, the portion of the non-exposed surface (2) having an area equal to or larger than the exposed portion from the slit portion (17) is painted like the exposed surface (3). .

As illustrated in FIGS. 1 to 3, grooves are formed at the draining part (4) where the slit part (17) of the roof tile (1 L) (1 R) to be loaded is located. The mountain-shaped draining portion (41) is provided by the above-described method, and effectively prevents rainwater or the like from entering from the slit portion (17). The mountain-shaped drainer (41) has a planar shape, and the cut-in depth of the slit (17) is shown in FIGS.
As shown in FIG. Needless to say, the position shape may be such that the peak is protruded, contrary to FIGS.

FIGS. 4 (A) and 4 (B) are plan views each illustrating an example of a roof surface in which roof tiles to be loaded are stacked by 1/2 and 1/3 respectively. With the roof tile of the present invention, such a varied roof surface can be easily realized.

[0015]

As described in detail above, according to the invention of this application, it is possible to easily change the positional relationship between the slits of the roof tiles such as the upper and lower flat roof tiles to be loaded, and the exposed surfaces can be changed from the slits. A new roof tile that does not impair the appearance even when it is exposed and that is excellent in waterproofness is provided.
