It is an explanatory view showing a flat tile. (A) shows the AA cross section of FIG. 1, (b) is explanatory drawing which shows the BB cross section. (A) shows a state in which rainwater is blocked by primary water return, (b) shows a state in which rainwater is blocked upstream from the second water drain, and (c) is a state in which rainwater is blocked upstream from the second water drain FIG. It is explanatory drawing which shows the example of a change of a flat tile.

  Hereinafter, an embodiment of a flat tile according to the present invention will be described in detail based on the drawings.

  FIG. 1 is an explanatory view showing a flat tile. FIG. 2 is an explanatory view showing a cross section of the flat tile shown in FIG. FIG. 3 is an explanatory view showing a state in which rainwater is blocked.

  First of all, as shown in FIG. 1, flat tile 1 is installed on the roof of a house, and after installation, rainwater flows down the surface, with inclined surface 2 and flat tiles 1, 1 installed on the left and right It is comprised with the under lap part 3 which is an overlapping part.

  Among them, the sloping surface 2 has a drooping portion 4 bent toward the back surface side at the front end (the lower side in FIG. 1 is taken as the front) and a ridge extending toward the left and right ends from the center The first water return 5, 5 is provided, and the second water return 6 formed in a step shape is provided behind the first water return 5, 5. And between the first water return 5, 5 and between the first water return 5 and the second water return 6, the drainage part 9 which discharges the rainwater which has entered between these from the inside of the dripping part 4 to the outside. Is formed. Further, on both the left and right ends of the inclined surface 2 are provided ridges 10, 10 of ridges that prevent rainwater flowing down the inclined surface 2 from flowing into the underlap portion 3.

  Next, as shown in FIG. 2 (a), in the A-A cross section of FIG. 1, the second water return 6 is a second water having a higher step than the second water return front stage 7 and the second water return front stage 7. It is formed in a multistage structure provided with the post-separating stage 8 and, as shown in FIG. 2 (b), in the B-B cross section of FIG. .

The installation to the roof 20 by the flat tile 1 comprised in this way is performed as follows. However, in order to distinguish flat tiles in the installation direction, reference numerals 1a, 1b,. The same applies to each configuration.
First, as shown in FIG. 3A, flat tile 1a is installed on the roof 20. And the other flat tile 1b is installed in the inclined surface 2a of this flat tile 1a.
At this time, the hanging part 4b of the flat tile 1b needs to be installed in front of the first water return 5a of the flat tile 1a in order to prevent the rainwater 15 from flowing into between the flat tiles 1a and 1b after installation. However, in particular, the distance B between the tip of the drooping portion 4b of the flat tile 1b and the first water flap 5a of the flat tile 1a is set to be equal to or less than half the height A of the drooping portion 4b of the flat tile 1b. Thereafter, flat tiles 1c, 1d, ... not shown are similarly installed to form a row. At this time, flat tiles 1 a, 1 b,... Are provided on the roof 20 by installing the rows of the other flat tiles 1 on the underlap portion 3 so as to overlap each other.

Next, a structure will be described which prevents rainwater from invading between the flat tiles 1a and 1b set up when it rains.
First of all, most of the rainwater flows down the surface of the inclined surface 2b of the flat tile 1b from the tip of the drooping portion 4b to the flat tile 1a in the lower stage because the roof 20 is gently inclined when it rains. Then, it will flow down the surface of the inclined surface 2a.

However, all the rain water does not necessarily flow down from the tip of the drooping portion 4 b onto the inclined surface 2 a as it is, and some of the rain water may flow inside the drooping portion 4 b.
In this case, as shown in FIG. 3 (a), although the rain water 15 will wrap around the inside of the tip of the hanging portion 4b, since the flat tile 1a is provided with the first water return 5a, It is blocked and can not exceed the first water return 5a, and then it flows down on the inclined surface 2a.
Even if the rainwater 15 exceeds the inclination of the first water return 5a, as shown in FIG. 3 (b), the second water return front stage 7a is provided behind the first water return 5a. Thus, it is blocked by the second water return front stage 7a.
Then, after the rainwater 16 blocked by the second water return front stage 7a flows into the drainage portion 9a formed between the first water return 5a and the second water return front stage 7a, the figure on the slope 2 is shown. It will flow down in the direction indicated by the arrow 1 and is discharged from the inside to the outside of the hanging portion 4b of the flat tile 1b.

Also, as shown in FIG. 3 (c), even if the rainwater 15 not only passes through the first water return 5a, but also exceeds the second water return front stage 7a, the second water return front stage 7a has a second back. Since the second water return post-stage 8a formed higher than the water return front-stage 7a is provided, the second water return post-stage 8a will block the rainwater 16 beyond the second water return front-stage 7a. .
Then, after the rainwater 16 stopped by the second water return stage 8a flows down on the second water return stage 7a and flows into the drainage portion 9a, the rain water 16 is stopped by the second water return stage 7a As in the case, it flows into the drainage portion 9a and flows down on the inclined surface 2a in the direction indicated by the arrow in FIG. 1 and is discharged from the inside to the outside of the drooping portion 4b of the flat tile 1b.

  The tiled structure of flat tile 1 and flat tile 1 configured as described above is such that the distance from the tip of the hanging portion 4b of the flat tile 1b placed on the inclined surface 2a to the first water return 5a is the hanging portion of the flat tile 1b By installing the first water return 5a so as to be equal to or less than half the height of 4b, it is possible to prevent the inflow of rain water 15 after installation. Furthermore, installation is easy because the structure is simple.

  Further, a second water return 6 formed in a step shape is provided behind the first water return 5, 5 and a concave drainage portion 8 is formed between the first water return 5 and the second water return 6. Prevents the rainwater 16 from flowing.

  Furthermore, since the second water return 6 is composed of the second water return front stage 7 and the second water return later stage 8 having a higher level than the second water return front stage 7, the inflow of rainwater 16 is blocked.

In addition, the provision of the water return 10, 10 at both ends of the inclined surface 2 prevents rainwater from flowing into the underlap portion 3.
Prevent drainage water from entering the first water return 5.

  The flat tile according to the present invention is not limited to the above-described embodiment at all, and can be appropriately modified without departing from the scope of the present invention.

  For example, although the second water return 6 has a multistage structure, the second water return 6 does not have to be configured with only the second water return front stage 7 and the second water return back stage 8, and even if a step higher than the second water return later stage 8 is additionally provided. As long as it is a structure in which rain water is drained from the concave drainage part 9 formed between these, it can change suitably.

  In addition, as shown in FIG. 1, the drainage of rain water 16 is drained from the direction indicated by the arrow at the center on the rear end side of the inclined surface 2 from between the first drainage 5 and the second drainage 6 It is not always necessary to drain water from this direction, and as long as it is a structure for draining the rainwater 16 flowing between the first water return 5 and the second water return 6, it may be drained from another position and can be changed appropriately It is.

Besides, as shown in FIG. 1, in the flat tile 1 of the present invention, the first water return 5 and 5 are formed flat, and the rain water 15 is drawn from the drainage portions 9 and 9 in the direction indicated by the arrows. The structure is to drain water, but as shown in FIG. 4, the end portions of the rear end side center side are connected by the first water return 5 and the second water return 6 to provide the weirs 11 and 11, and the rain water 15 is a drainage portion It is good also as a structure which flows down to the both left and right ends of 9, 9, and can be changed suitably.
In this case, the rainwater 15 flowing down the drainage portion 9 on the left side is drained from the underlap portion 3 and the rainwater 15 flowing down the drainage portion 9 on the right side is the underlap portion 3 of the flat tile 1 installed next Drained from the
