Description

[Detailed description of the invention] The present invention is based on the structure of an eave tile used for tile roofs, specifically the lower end of roofs covered with Japanese-style ceramic tiles whose normal cross-sectional shape is a smooth curved waveform, that is, the rim. Regarding.

Generally, the rod part 1 of a tiled roof is covered with an eaves tile 2, as shown in Fig. 9. It consisted of Manjubu 2b.

For this reason, the eaves tiles 2 are much more expensive than ordinary tiles 3, and the tile roofing work becomes a problem, which increases the cost of roofing work. The eave tile 2 was sometimes lifted up and even blown away when the portion 2a was exposed to the wind.

In addition, rainwater flowing on the surface of the eave tile 2 easily wraps around the back surface of the tile due to surface tension and the influence of wind, which wets the eave 5 and causes it to rot prematurely, causing the tile roof needle part 1 to fall off. was.

Therefore, in the present invention, the shape of the eaves tile is approximately the same as that of a normal frame tile, and a notch is provided on the surface of the lower end of one side of the eave tile by cutting only the surface part, so that the eave tile overlaps with the adjacent eave tile. In addition, the lower end of the eave tile is sloped smoothly so as to protrude downward, and a continuous uneven part consisting of a number of grooves extending laterally is formed on the back surface of the lower end. It is an object of the present invention to provide an eaves tile that prevents rainwater etc. from flowing up to the back surface of the eaves tile and thereby eliminates the above-mentioned drawbacks.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 8.

As shown in FIG. 1, most of the tiled roof 6 is covered with cross tiles 3, and the uppermost position, that is, the ridge part 9, is covered with a ridge part 9a made of tiles, metal plates, etc. Further, the side end portions, that is, the sleeve portions 10 are covered with sleeve accessories 10a made of sleeve tiles, metal plates, or the like.

The lower end portion of the roof 6, that is, the rod portion 1, is covered with eaves tiles 11 according to the present invention.

As shown in FIGS. 2 to 4, the eaves tile 11 is made of ceramic that is approximately rectangular and has a predetermined size. It's broken.

Furthermore, as shown in detail in FIG. 2, the surface 11a of the eave tile 11 has an upper end, that is, a portion that overlaps with the crosspiece tile 3, and a negative end, that is, a portion that overlaps with the adjacent eave tile 11' at a lower position. Convex strips 12a and 12b for draining are formed on each side, and holes 13 for nailing are formed in the overlapped portions with the crosspiece tiles 3.
However, the convex portion 15 has a smaller diameter on the surface 11a side,
and a hole 16 for a copper wire or secondary needle with a larger diameter on the back side.
, 16 are drilled.

Furthermore, at the lower end corner of the surface 11a of the eaves tile 11, that is, at the lower end corner of the portion that overlaps the adjacent eaves tile 11' at the lower position, as shown in detail in FIGS. A transversely long notch 17 is formed by cutting only the surface, and the other corner of the upper end is partially cut off to form an engaging portion 19 for engaging the crosspiece tile 3.

On the other hand, on the back surface 11b of the eave tile 11, as shown in FIG. A protrusion 21 for draining water is formed on.

Furthermore, the lower end portion 27 of the eave tile 11 is smoothly inclined downward as shown in FIGS. 7 and 8.
Therefore, a protrusion 22 that slightly protrudes downward is formed at the tip of the inclined portion.

Further, on the back surface of the lower end portion, a large number of deep grooves 26a and shallow grooves 126b are formed in the concave portion 23 through a gentle slope 25 and extending laterally in parallel, and these grooves 26a and 26b are continuous. The concave and convex portions 26 are formed.

Since this embodiment has the above-described configuration, the eaves tile 11 has a draining ridge 12 on the surface 11a, as shown in FIG.
b are placed in the lower position, partially overlapping the adjacent eaves tiles 11', and are installed one after another, and then nails are driven through the holes 13 and copper wires are passed through the holes 16 or sub-needle is driven into the holes 16. , firmly fixed.

At this time, the protrusion 22 located at the tip of the back surface of the adjacent eave tile 11' comes into contact with the lower end of the overlapping part of the eave tile, but as shown in FIGS. 5 and 6, the lower end of the overlapping part of the eave tile Since the corners are cut-out parts 17, the protruding parts 22 are received in the cut-out parts 17 without interference, and the eaves tiles 11 can be installed one after another while neatly overlapping each other.

Further, the draining ridge 21 is gradually reduced at the lower end inclined portion 27 and is configured to be low, so that the draining ridge 21 of the adjacent tile 11' is approximately on the surface 11a without interfering with the lower tile. make sure there are no gaps.

In addition, since the hole 16 is located on the convex portion 15, rainwater will not flow in through the hole 16, and the hole 16 has a smaller diameter on the surface 11a side and is not blocked by secondary needles or the like. Therefore, there is very little chance of raindrops getting in.

As shown in FIG. 7, rainwater flowing down the concave portion 23 of the front surface 11a of the eave tile 11 tries to wrap around the back surface 11b due to surface tension, but the lower end of the back surface slopes downward and protrudes. Since the section 22 is formed, rainwater flows onto the slope 25.
22, and most of the time it falls from the protrusion 22.

Furthermore, rainwater may travel up the slope 25 due to the influence of wind, etc.;
The adhesive force with the back surface 11b of the tile is gradually broken due to the continuous uneven portion 26 where a large number of b are formed, and the water droplets grow in a drop shape as shown by the chain line and fall down, and do not reach the eaves 5. do not have.

As explained above, according to the present invention, the beam part 1 of the tiled roof 6 is also roofed using the eave tile 11 which is substantially the same as the normal beam tile 3 without the hanging part 2a and the manju part 2b. As a result, the structure of the eaves tile 11 is simple, it can be manufactured at low cost, and it requires less space during transportation and storage. Since the cutout part 17 is formed, the eaves tiles 11' can be stacked neatly without interfering with the adjacent eave tiles 11', making the tile roofing work easier, and the cost of roofing work can be significantly reduced.

Further, the lower end portion 27 of the eaves tile 11 is sloped smoothly downward, with its tip portion 22 protruding downward, and a continuous uneven surface consisting of a large number of grooves 26a, 26b is formed on the back surface of the lower end portion. As a result, these uneven surfaces work together to gradually break the adhesive force of the rainwater that has flowed up the slope 25, causing the rainwater to grow into drop-shaped droplets and fall. Although the structure is simple, rainwater does not rise up to the eaves 5 even under the influence of surface tension and wind, prevents the eaves from collapsing, prevents the eaves 5 from rotting early, and extends the lifespan of the tile roof needles 1. can be extended.

Furthermore, since the lower end portion 27 of the eaves tile 11 is sloped smoothly downward, it is not directly exposed to the wind like the hanging portion 2a of the conventional eaves tile 2, but is exposed to the wind along the smooth inclined surface. This allows the eaves tiles 11 to escape to the rear, and the eaves tiles 11 will not be lifted up even in the event of a typhoon, and together with the fixation through the holes 16, the structure is strong against wind.
