Description

[Detailed Description of the Invention] The present invention relates to a roof tile, and more particularly to a roof tile structure that prevents rainwater from rising upward from the overlapping portions of the roof tiles.

Conventionally, roof tiles have been provided with drainage protrusions on the rear and flat ends of their surfaces, and sag on the edges and crests of the back surface, and these protrusions and sag have prevented rainwater from rising upward. Ta. However, when there is heavy rain and wind such as during a typhoon, the conventional tiles cannot be used.
Due to the influence of the wind, the falling rainwater accumulates in the overlapping parts of the tiles, and then the wind becomes a jet airflow from the gap between the drip and the tile surface and blows through the draining protrusion made of a tapered surface, and the rainwater is removed by the airflow. was climbing up the protrusion and causing rain leaks.

Therefore, in the present invention, a protrusion is provided on the back side of the tile and a groove is provided on the surface of the tile in the overlapped part of the roof tiles, and the protrusion is arranged so that it fits into the groove, and the protrusion for draining and hanging The object of the present invention is to provide a roof tile that eliminates the above-mentioned drawbacks by dividing the space of the overlapping roof tile portion formed by the roof tile into a plurality of chambers.

Embodiments of the present invention will be described below with reference to the drawings.

Roof tile Details: On the surface A of the Japanese-style baked tile 1, there is a
As shown in the figure, draining protrusions 2, 2 are formed to protrude upward at the rear butt 1a and the flat end 1b, and these protrusions 2 have their inner upper portions largely inward, as shown in Fig. 3. An overhang 3 is formed by bulging toward the side. Furthermore, these protrusions 2
V-shaped grooves 5, 5 are formed parallel to and spaced inward at a predetermined interval, and a large number of outlet ports 6 are formed in the groove 5 at predetermined intervals. Furthermore, a shallow groove 7 is formed slightly inward of the V-groove 5 on the rear hip 1a side. On the other hand, on the back side B of the tile 1, as shown in FIG. V-shaped protrusions 10, 10 that largely protrude inwardly from the gap are formed, and further V-shaped protrusions 1 at the edge 1c are formed.
A horizontal rib 11 is formed at the rear of 0. In addition, in FIG. 1, the reference numeral 12 indicates a nail hole for fixing tiles;
13 and 14 are notches. Further, in Fig. 2, 15 and 16 are stabilizing claws installed at a predetermined distance apart, and 17 is a flat surface located in the valley.
7 comes into contact with the roofing 19 to stably support the tiles. Furthermore, 20... is 2 in the rear half of the tile 1.
A large number of wart-like projections extend in the longitudinal direction of the strip, and the height of these projections 20 decreases gradually toward the rear end 1a, and comes into contact with the roofing when the tiles are installed. Further, 21... is a wart-like projection, and 22 is a flat surface. When using a scratch, these projections 21 and the flat surface 22 support the tile by coming into contact with the scratch.

As shown in FIG. 3, the horizontal rib 11 of the upper tile 1 is attached to the rear side of the rear protrusion 2 of the lower tile 1'.
Tiles are sequentially laid with the front surfaces of the tiles in contact with each other, and at this time, the V-shaped protrusions 10 are fitted into the V-shaped grooves 5, and the sagging edges 9 correspond to the grooves 7. There is. The groove 7 is provided to prevent the edge part sag 9 from interfering with the lower tile 1' and affecting other parts when the tile 1 is twisted. Similarly, when the tiles are overlapped in the horizontal direction, the peak side protrusions 10 of the upper tile are fitted into the flat V-grooves 5 of the lower tile.

Since this embodiment has the above-described configuration, during a typhoon, as shown in FIG. 3a, rainwater infiltrates together with the wind through the gap between the sag 9 and the groove 7. Then, the infiltrated rainwater flows into the V-shaped groove 5,
Since the V-shaped protrusion 10 is fitted into the V-shaped groove 5, the flow of air is completely blocked by the rainwater flowing into the groove 5 and the protrusion 10, and the sag 9 and the protrusion 1
A turbulent flow is generated and the atmospheric pressure is increased in the chamber C between the groove 5 and the protrusion 10, thereby preventing a large amount of rainwater from entering the chamber C,
and prevents it from climbing up to the chamber D constituted by the protrusion 2. In addition, even if a small amount of wind and rain enters the chamber D, turbulence will occur in the chamber D due to the overhang 3 of the draining projection 2, and furthermore, the amount of air passing through will be significantly restricted due to the contact between the horizontal ribs 11 and the projection 2. As a result, the wind force is significantly weakened, and rainwater is therefore prevented from running up the protrusion 2, particularly the overhang 3, due to the wind. Note that the rainwater that has entered the groove 5 is discharged from the outlet 6 when the pressure from the wind is removed.

Further, as shown in FIG. 3b, dust H accumulates and hardens in the grooves 7 and V-shaped grooves 5 on the surface A of the roof tile 1 over time. Then, the dust H acts as a seal, and the dust H accumulated in the chambers C and D, particularly the protrusion 10 and the groove 5, completely seals the chamber D, completely preventing rainwater from rising upward.

Generally, the draining protrusion 2 is attached to the overhang 3 for the purpose of removing it from the mold during molding.
Although it is difficult to form the overhang 3, it is possible to easily form the overhang 3 by the method shown in FIG. That is, when pressing the soil to form the entire tile, a protrusion 3' that protrudes upward along the inside of the draining protrusion 2 is formed as shown in a. Then, in the condition of undried wasteland IM, ridge 2
5a and a flat part 25b, the mold 25 is attached to the protrusion 2.
Press from above. Then, as shown in b,
The upwardly protruding protrusion 3' is turned inward by the mold 25, and the overhang 3 is formed. At this time, a V groove 26 is formed on the upper surface of the protrusion 2 by the protrusion 25a of the mold 25.
can be used as a basin to drain rainwater that tends to rise due to surface tension.

In addition, although the above-mentioned Example demonstrated the Japanese-style baked tile, it is needless to say that it is applicable not only to this but also to other tiles, such as a cement tile, a PBC tile, or a Western-style tile.

As explained above, according to the present invention, the protrusions 10 formed on the back surface B of the tile can form the grooves 5 formed on the surface A of the tile.
Since the space of the overlapping roof tiles formed by the draining protrusion 2 and the sag 9 is divided into a plurality of chambers C and D, the rainwater itself that has entered the groove 5 along with the wind is absorbed into the ridge 10. It is possible to form a seal and block the air flow between the divided chambers C and D, and to prevent rainwater from entering with the wind. The dust H acts as a seal and can completely prevent rainwater from rising upwards, thereby reliably preventing rainwater from leaking even during a typhoon.
