The rainwater or the like that has flowed over the part (51) is guided to the left and right, and is surely poured into the drain plate (3). Moreover, the groove can prevent the capillary phenomenon that occurs between the gap between the connection portion and the connection recess.

Here, the eave roof tile (60) located at the eave edge of the roof will be described. As shown in FIG. 8, the eave roof tile (60) is provided in the front of the flat roof tile (50) instead of the connection recess (55). Dripping (66)
Is provided. This drip (66) has protrusions (67) at both ends that protrude more to the left and right than the eaves tile (60) body.
have. Accordingly, the eaves gutter (4) can be hidden by making the eaves tiles (60) droop (66) adjacent to each other on the left and right with the gap (10) contiguous to improve the eaves edge design.

In addition, the sleeve eaves tiles (70) placed on the left and right ends of the roof are the 9th
As shown in the figure, the roof tile (60) has the same drip (66) and the tile (78) provided on the side of the tile roof body.
Further, the sleeve roof tile (80) has a sag (78) only on the side portion of the roof tile main body as shown in FIG.

Next, explaining the method of constructing this tiled roof, first, as shown in FIG. 11, a draining plate (3a) is attached to the upper surface of the eaves end of the Nojizaka (1), and further on the Nozoku board (1). A plurality of mounting base materials (2) are arranged and fixed. At this time, the interval between the mounting base materials (2) is set to a size such that the sags (66) of the eave roof tiles (60) adjacent to each other on the left and right are continuous. Subsequently, as shown in FIG. 12, the drainage plate (3) is arranged between the respective mounting base materials (2), and both ends of the drainage plate (3) are fixed by nails (25) or the like to the upper surface of the mounting base material (2). Fixed to. Then, as shown in FIG. 13, the mounting base material (2)
Fix the gutter receiving metal fitting (7) on the upper surface of the eaves edge.

Then, roof that flat tile (50 mag). That is, first, the eave tile (60, 70) is placed on the upper surface of the eave end of the mounting base material (2), and the nail hole (52) of the connecting part (51) and the eave tile (60, 70) main body center. The eave roof tiles (60, 70) are fixed to the mounting base material (2) by inserting and hitting the nails (20) into the nail holes (62) transparently provided in the part. Then, as shown in FIG. 14, the eaves tile (60,7
The connecting portion (51) of (0) is made to correspond to the connecting recess (55) of the roof tile (50) or sleeve tile (80), and the flat tile (50) or sleeve tile is provided on the upper surface of the mounting base material (2). Place (80) and fix with nails (20). In this way, the roof tiles (50, 80) may be sequentially fixed to the rear of the mounting base material (2). Moreover, roof tiles (50,60,70,
Since 80) has a chevron shape, it can be placed so as to cover the base material, which facilitates positioning.

In addition, between the eave tile (60, 70) and the mounting base material (2),
Arrange the packing (9) as shown in FIG. 2 to support the eaves tiles (60, 70).

Then, the eaves gutter (4) is fixed by the gutter receiving fitting (7), and the tile roof is completed.

Next, the effect of the drainage structure of the tiled roof will be described in more detail. In this tiled roof, the tiles (50, etc.)
The rain and snow that has fallen on the roof (50, etc.) is flowed in the left and right direction of the main body, and is poured into the drain plate (3) from the space (10) between the roof tiles (50, etc.) and the roof tiles (50, etc.). Therefore, the roof tile does not need a gradient for flowing in the front-back direction. However, it is enough that the drain plate has a slight slope that allows drainage. Then, rainwater, snowmelt water and the like flow to the edge of the eaves by the drainage plate (3), are received by the eaves gutter (4) and are discharged to the outside.

Also, if the roof tiles are flush with each other, there is no need to fold the "tile roof return slope" into the "roof slope". This has the effect of reducing the number of roof tiles that turn over.

Therefore, in this tiled roof, the long drainage plate (3) provided under the tiles (50 etc.) reliably receives rainwater and the like, and the long and seamless drainage plate does not leak water. It is discharged to the eaves gutter (4). Therefore,
Unlike conventional tiled roofs, it is possible to set the gradient in a very wide range from 1/100 to 100/1, and it is possible to perform a novel design that was previously impossible.
Also, it becomes possible to take a large living space.

Furthermore, in this tile roof drainage structure, tiles (50 etc.)
By providing the drainage plate (3) under the roof, unlike the conventional tiled roof, the eaves gutter (4) can be installed inside the hanging (66) of the eaves tile (60, 70). Therefore, it is possible to improve the linear aesthetics of the eaves end of the tiled roof, and the eaves gutter (4) is never damaged by snow. In addition, the rainwater poured into the eaves gutter has its flow velocity varied depending on the amount of rainfall, so that the pouring tip fluctuates back and forth. It may leak and be poured. However, the structure of the present invention is such that the leaked rainwater is eaves tiles (60, 70).
Since it hits the inner surface of the drip (66) and is bounced back, rainwater can be reliably received by the eaves gutter (4).

Also, in this tiled roof, the tiles that are adjacent to each other on the left and right (50 etc.)
And a gap (10) between the roof and the roof tile (50 etc.),
Since the roof tiles are fixed with nails, it is not necessary to place thatch on the base plate (1). Therefore, the weight of the entire roof can be reduced, the earthquake resistance can be improved, and the roof frame can be advantageously designed.

Furthermore, in this tile roof, Nojizaka (1) and tile (50
Etc.), a space (S) extending from the edge of the eaves to the ridge is formed, so that it has excellent air permeability, can prevent the roof from getting wet, and can exhibit an excellent heat insulating effect.

The present invention is not limited to the above-mentioned embodiment, and the shape of the drain plate (3) is appropriately changed, or only the roof tiles on the eaves are provided with grooves, notches, gaps or the like for pouring rainwater into the drainage means. Or by changing the shape of the roof tile,
The roof substrate itself is waterproofed to be used as a drainage means, or the eaves gutter attachment structure or attachment procedure may be appropriately changed, for example, by appropriately changing the scope without departing from the spirit of the present invention. Good.

(Effects of the Invention) As described in detail above, in the tile roof drainage structure according to the present invention, the eaves trough is hidden so that the eaves trough is hidden inside the hanging eave tiles, which is completely different from the conventional tile roof. Since it can be installed, it has an excellent aesthetic effect at the eaves edge and an excellent effect on the maintenance of the eaves gutter.

In addition, it is possible to set the roof slope in a wide range, and the roof appearance is flat and neat, and it is possible to perform a novel design that was not possible in the past, construction is easy and reliable, and roofing is unnecessary. By increasing the air permeability of the roof substrate, it is possible to achieve excellent effects on the drying and heat insulation of the roof.
