Abstract

PROBLEM TO BE SOLVED: To provide a pantile, in which a back-board effect is improved even when rainwater blows in from any direction and the drainage properties of rainwater infiltrating among superposed tiles are enhanced and which can elevate the appearance of a roof. SOLUTION: In the tile in which a tail-side back board 3 is formed at the tail section of a main body 2, a groove section 10 is formed along the lateral direction of the main body 2 on the head side from the tail-side flashing 3. The flow of rainwater blowing up the surface of the main body 2 can be weakened by the groove section 10. Since a flowing onto the surface of the main body 2 on the tail side from the groove section 10 of rainwater entering in the groove section 10 can be prevented, the back-board effect in the tail-side flashing 3 can be improved. Since it is viewed as if the two tiles were roofed by one tile when the roof is roofed, the roofing of the tiles more than the number of the practically used tiles is viewed. Accordingly, the roof can be shown in a size larger than the actual area of the roof.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof tile. The roof tiles are roughly classified into two types, that is, the Japanese roof tiles and the Western roof tiles, depending on whether the building for the roof is Japanese style or Western style. J-shaped ridges are representative of Japanese-style ridges, and F-type ridges and S-type ridges are representative of Western-style ridges. The present invention relates to such a roof tile.

2. Description of the Related Art FIG. 5 is a plan view of a conventional crosspiece 100. FIG. 6 is an external view of a conventional roof tile 100 that is roofed. FIG. 7 is an explanatory view of a mounting state of the conventional crosspiece 100. As shown in FIGS. 5 to 7, on the roof of the building, the ridges 100 are laid so that the adjacent ridges 100 are overlapped with each other. At this time, between the right and left ridges 100, the ridge 10 of the right ridge 100 is placed on the side water refill 102 of the left ridge 100.
Arrange so that 1 can be placed (see Fig. 7 (B)),
The 00s are arranged so that the head 103 of the upper roof tile 100 is placed on the bottom side water sink 104 of the lower roof tile 100 (see FIG. 7 (A)). For this reason, there is no gap between the adjacent ridges 100, so that even if it rains
It is possible to prevent the rain leak from occurring because the rain does not permeate between 0 and the roof tile 100.

However, when it rains with a strong wind such as a typhoon, rainwater is blown up toward the bottom side of the lower ridge 100, and the surface of the lower ridge 100 and the ridge 100 on the butt side. Rainwater enters between the back of the head 103 and the back. Then, since the height from the surface of the roof tile 100 to the upper end of the tail side water return 104 of the roof tile 100 is not so high, if a large amount of rainwater flows in, the bottom side water return 104 should stop all the rainwater. However, rainwater may flow to the upper end of the tail side water return 104. In this case, the upper stile
Back side of the head 103 of the 100 and bottom side of the roof tile 100
There is a possibility that rainwater will seep in from between and rain leaks will occur.

In order to solve this problem, the conventional stile 10
A plurality of auxiliary water return sections 105 are provided on the surface of 0. As shown in FIGS. 5 and 7 (A), the auxiliary water return portion 105 is formed in a protrusion shape along the horizontal direction of the crosspiece 100, and is formed so as to be discontinuous with each other.
For this reason, rainwater flowing toward the butt side can be stopped on the surface of the roof tile 100, and the amount of rainwater flowing to the butt side water sink 104 can be reduced.

[0005]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The 100 has the following problems (1) to (2). (1) Since the auxiliary water return section 105 is formed along the horizontal direction of the roof tile 100, rainwater flowing straight from the head side to the hip side on the surface of the roof tile 100 can be dammed up, but on the hip side. When rainwater is blown up diagonally,
Since rainwater can enter between the auxiliary water return sections 105,
It is not possible to reduce the amount of rainwater that flows to the tail side water return 104 of the lower sash 100. However, the auxiliary water return section
If 105 is one continuous projection from the crosspiece 101 of the roof tile 100 to the side water return 102, the amount of rainwater that exceeds the auxiliary water return unit 105 and enters between the auxiliary water return unit 105 and the tail side water return 104. However, if the rainwater that entered between the auxiliary water return section 105 and the tail side water return section 104 or the dust that entered with the rainwater, etc., is caught between the surface of the roof tile 100 and the auxiliary water return section 105, g (see FIG. 7 (A)), and there is a problem that the roof tile 100 is corroded due to the influence of salt contained in rainwater, dust, and the like. In particular, in coastal areas, there is a problem in that the amount of salt contained in rainwater, dust, etc. is large, so that the corrosion of the roof tile 100 becomes significant. Therefore, it is not possible to reduce the amount of rainwater that flows to the tail side water return 104 of the head side sash 100, and to improve the drainability of rainwater that enters between the auxiliary water return section 105 and the tail side water return 104. It was (2) Auxiliary water return section 105 is provided at the bottom of the roof tile 100, but no auxiliary water return section is provided at the side end of the roof tile 100, so rainwater blown in from the side, that is, to the right Back of ridge 101 of ridge 100 and side of ridge 100 on the left side
If the amount of rainwater blown into the surface of 2 increases, there is a problem that rainwater easily infiltrates between the two.

The tiles were introduced from China 1400 years ago and were improved to the present shape of the roof tiles in the Edo period. However, the basic shape of the roof tiles has not been greatly improved until then. This is because the idea that the shape of the roof tile industry should not be changed has been firmly established, and the act of changing the basic shape of the roof tile is a god (spirit ) Has been regarded as a taboo as an act without fear.

In view of such circumstances, the present invention has a high water repelling effect regardless of the direction in which rainwater is blown, the drainage of rainwater between overlapping tiles is good, and the roof appearance can be made beautiful. The purpose is to provide.

According to a first aspect of the present invention, there is provided a crosspiece of claim 1 in which a bottom side water barb for supporting the piled roof tiles is formed at the bottom of the main body. It is characterized in that a groove is formed along the lateral direction of the main body on the head side with respect to the hip side water repellent. According to a second aspect of the present invention, in the invention as set forth in the first aspect, the groove portion is such that the groove portion has a damming surface formed between a bottom portion of the groove portion and a main body surface on the rear side of the groove portion, and a head portion side of the groove portion. And a lead-in surface inclined downward from the surface of the main body toward the bottom of the groove. According to a third aspect of the present invention, in the invention as set forth in the first or second aspect, the crosspiece has an acute angle formed between the damming surface and the introduction surface of the groove portion. According to a fourth aspect of the present invention, in the invention according to the first, second or third aspect, the bottom of the groove portion is formed into a flat surface. The roof tile of claim 5 is the one of claims 1, 2, and 3.
Alternatively, in the invention described in 4, the auxiliary water return portion, which is recessed from the surface of the main body, is formed in the butt portion of the main body, on the head side of the butt side water return. According to a sixth aspect of the present invention, in the invention as set forth in the first, second, third, fourth, or fifth aspect, the auxiliary water return portion is formed between the bottom portion of the auxiliary water return portion and the main body surface on the head side of the auxiliary water return portion. When the main body is attached to the roof, the inclined surface of the auxiliary water return section is directed from the bottom of the auxiliary water return section toward the main body surface on the head side of the auxiliary water return section. Characterized by a downward tilt. The roof tile of claim 7 is the same as claim 1, 2,

According to the first aspect of the present invention, a part of the rainwater flowing on the surface of the roof tile enters the groove, so that the flow of the rainwater blown up can be weakened by the groove. Moreover, since the rainwater that has entered the groove flows along the groove and is discharged from the side of the roof tile,
It is possible to prevent rainwater that has entered the groove from flowing to the main body surface on the tail side of the groove. Therefore, it is possible to reduce the amount of water that enters the overlapping portions of the vertically adjacent roof tiles, and thus it is possible to improve the water repelling effect in the tail side water repelling. Also, when the roof is roofed, two roof tiles look like one roof tile, so it seems that more roof tiles are used than the number of roof tiles actually used. Therefore, the roof can be made larger than the actual area of the roof. Moreover, since the groove looks shiny and whitish, the appearance of the roof becomes beautiful, and a characteristic appearance different from that of the conventional roof in which the roof tile is roofed can be exhibited. According to the invention of claim 2, since the introduction surface of the groove is lower than the body surface on the rear side of the groove, rainwater blown up on the body surface on the head side of the groove can be dammed by the damming surface.

Moreover, it is possible to prevent rainwater that has entered the groove from flowing to the surface of the main body on the tail side of the groove. According to the invention of claim 3, since the angle formed between the damming surface of the groove and the introduction surface is an acute angle, rainwater blown up on the body surface on the head side of the groove can be dammed surely by the damming surface. Therefore, it is possible to reliably prevent the rainwater that has entered the groove from flowing to the body surface on the rear side of the groove. According to the invention of claim 4, since the bottom portion is formed into a flat surface, it is possible to prevent rainwater, dust and the like from accumulating in the groove portion. Therefore, it is possible to prevent the roof tiles from being corroded by the salt content contained in rainwater, dust, and the like. According to the invention of claim 5, since the auxiliary water return part is recessed from the main body surface, the height from the bottom of the auxiliary water return part to the upper end of the hip side water return is high. Therefore, even if rainwater blows into the auxiliary water return section, the rainwater does not reach the upper end of the tail side water return, so the rainwater does not permeate between the roof tiles above and the upper end of the back side water return, and a rain leak occurs. Can be prevented. According to the invention of claim 6, the auxiliary water return portion is recessed from the surface of the main body, and the inclined surface of the auxiliary water return portion is inclined downward from the end on the hip side water return side when the roof tile is attached to the roof. Since it is formed, the drainage of the rainwater flowing to the auxiliary water return section can be improved.
Moreover, since it is possible to prevent rainwater, dust, etc. from accumulating, it is possible to prevent the roof tiles from being corroded by salt contained in rainwater, dust, etc. According to the invention of claim 7,
Auxiliary water return section is also provided on the side of the roof tile, and since the height from the bottom of the auxiliary water return section to the upper end of the side water return is high, even if rainwater blows in from the side, Does not infiltrate between the upper roof tile and the upper end of the side wall,

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the crosstile 1 of the present embodiment. 2A is a sectional view taken along the line IIA-IIA in FIG. 1, FIG. 2B is a sectional view taken along the line IIB-IIB in FIG. 1, and FIG. It is an X section enlarged view. FIG. 3 is an external view of the roof tile 1 of the present embodiment. As shown in FIG. 3, the crosspiece 1 of the present embodiment is used by stacking adjacent crosspieces 1 on a roof of a house. Hereinafter, the shape of the crosspiece 1 of the present embodiment will be described. In addition, in FIG. 1, the head side of the roof tile 1 is defined as the lower side, and the bottom side of the roof tile 1 is defined as the upper side.

1 and 2, reference numeral 2 indicates the main body of the crosspiece 1, where the upper side in FIG. 1 is the hip side and the lower side is the head side. This stile 1 is a J-shaped stile, and its main body 2 has a corrugated cross section (see FIG. 2).
(B)).

The roof tile 1 has a flat plate F
There is no particular limitation as to the shaped crosspiece and the S-shaped crosspiece whose main body has an S-shaped cross section.

At the bottom end of the main body 2, a bottom side water return 3 is formed along the edge of the bottom side end. On the right side of the main body 2, a side water repellent 4 is formed along the right side edge. The bottom side water repellent 3 and the side water repellent 4 are for supporting the other roof tiles 1 when the other roof tiles 1 are stacked on the roof tile 1.

As shown in FIGS. 1 and 2, a groove 10 is formed on the surface of the main body 2 along the lateral direction thereof. The groove portion 10 is on the head side of the tail side water return portion 3 and the auxiliary water return portion 20 which will be described later, and when the other roof tiles 1 are stacked on the roof tile 1, the head side of the other roof tiles 1 that are stacked. It is formed so as to be positioned in the middle between the edge and the head-side edge of the roof tile 1. The groove portion 10 has a bottom portion 11 formed into a flat surface in a sectional view. An introduction surface 13 is formed between the lower end of the bottom portion 11 and the surface of the main body 2 on the head side of the groove portion 10. The introduction surface 13 is formed so as to incline downward from the surface of the main body 2 on the head side of the groove 10 toward the bottom 11. Moreover, the introduction surface 13 is formed so as to incline downward from the bottom portion 11 of the groove portion 10 with respect to the horizontal direction when the crosspiece 1 is attached to the roof.

Therefore, even if rainwater, dust, or the like enters the groove 10, the rainwater, dust, or the like can be reliably discharged from the groove 10. Therefore, it is possible to prevent rainwater, dust, etc. from accumulating in the groove portion 10, and it is possible to prevent the roof tile 1 from being corroded by the influence of salt contained in rainwater, dust, etc. In particular, in a coastal area where the amount of salt contained in rainwater, garbage, etc. is high, the effect of preventing the corrosion of the gantry 1 can be enhanced.

On the other hand, a damming surface 12 is formed between the bottom edge of the bottom portion 11 and the surface of the crosspiece 1 on the tail side of the groove 10. The damming surface 12 is formed such that the angle θ with the introduction surface 13 is, for example, 20 to 60 degrees, that is, an acute angle, the reason for which will be described later.

On the surface of the main body 2, the tail side water return 3
An auxiliary water return portion 20 is formed between the groove portion 10 and the head side, that is, the rear side water return portion 3. The auxiliary water return section 20 is formed so as to be recessed from the surface of the main body 2, and the height from the bottom section 21 to the upper end of the butt side side water return section 3 is high (FIG. 2 (A)). Therefore, even if rainwater blows into the auxiliary water return section 20, the rainwater does not reach the upper end of the tail side water return section 3. Therefore, it is possible to prevent rainwater from leaking from the rainwater without permeating between the upper end of the tail side water return 3 and the other roof tiles 1 stacked on it.

The auxiliary water return section 20 has a bottom section 21 and
It is provided with an inclined surface 22 formed between the auxiliary water return section 20 and the surface of the main body 2 on the head side. This inclined surface 22 is formed so as to incline downward from the end portion on the side of the tail side water return 3 when the stile 1 is attached to the roof. Therefore, the rainwater that has flowed to the auxiliary water return section 20 naturally flows down from the bottom portion 21 to the surface of the main body 2 on the head side of the auxiliary water return section 20, so that the rainwater that has flowed to the auxiliary water return section 20 is drainable. Can be higher. Moreover, since it is possible to prevent rainwater and dust from accumulating, it is possible to prevent the roof tile 1 from being corroded by the influence of salt contained in rainwater and dust. In particular, in a coastal area where the amount of salt contained in rainwater, garbage, etc. is high, the effect of preventing the corrosion of the gantry 1 can be enhanced.

The auxiliary water return section 20 has a bottom portion 21.
It is provided with a water stop surface 23 rising from the above. The water stop surface 23 is formed in an arc shape along the bottom side water return 3 of the crosstile 1. Therefore, even if rainwater is blown up obliquely on the surface of the main body 2, the rainwater can be efficiently collected at the lowest portion of the bottom portion 21 and then drained by flowing it on the inclined surface 22. The water repelling effect of 20 can be improved.

A lateral auxiliary water repelling portion 30 is formed inward of the lateral water repelling portion 4. The side auxiliary water return part 30 is formed so as to be recessed from the surface of the main body 2, and the height from the bottom thereof to the upper end of the side water return part 4 is high. Therefore, even if the rainwater blows into the side water return 4, the rainwater does not reach the upper end of the side water return 4. Therefore, it is possible to prevent the rainwater from leaking from the upper end of the side water return 4 and the other roof tiles 1 stacked on it, thereby preventing rain leakage. Further, since the side auxiliary water return part 30 also has a water stop surface formed in an arc shape along the side water return 4 of the stile 1, even if the rainwater is blown obliquely from the side, the rainwater will reach the bottom most. Since the water can be efficiently collected after being collected in the lower portion, the water return effect of the side auxiliary water return section 30 can be improved.

Next, the operation and effect of the crosspiece 1 of this embodiment will be described. FIG. 4 (A) is a schematic vertical sectional view when the roof tile 1 is roofed, and FIG. 4 (B) is a schematic horizontal sectional view when the roof tile 1 is roofed. As shown in FIG. 3 and FIG. 4, when a plurality of roof tiles 1 are stacked on the roof and light is reflected not only on the water leakage of the roof tile 1 but also on the damming surface 12 of the groove portion 10, one roof tile 1 And it looks like two roof tiles are roofed. For this reason, since it seems that the number of the roof tiles 1 used is larger than the number of the roof tiles actually used, the roof can be made larger than the actual area of the roof. Moreover, since the damming surface 12 of the groove portion 10 looks shiny and whitish, the appearance of the roof becomes beautiful, and a characteristic appearance different from that of the conventional roof in which the roof tile is roofed can be exhibited. When it rains, the roof is roofed so that the adjacent stiles 1 are overlapped with each other. Therefore, it is possible to prevent the rain from leaking between the adjacent stiles 1 and prevent the leakage of the rain. it can.

When it rains with a strong wind such as a typhoon, rainwater enters from between the back surface of the roof tile 1B and the surface of the roof tile 1A.
Rainwater can be prevented from entering between the rear surface of the ridge 1A and the upper end of the side wall 3 of the ridge 1A, and the lateral auxiliary water return portion 30 allows the upper ends of the side wall 4 of the ridge 1C and the side wall 4A of the ridge 1A. It is possible to prevent rainwater from entering between.
Therefore, it is possible to prevent rainwater from entering between the overlapping stiles 1 and causing rain leakage.

Of the rainwater flowing from the head side to the hip side on the surface of the main body 2 of the roof tile 1, the rainwater flowing on the surface of the main body 2 on the head side of the groove portion 10 reaches the auxiliary water return section 20. Then, the groove portion 10 is reached. Then, since the introduction surface 13 of the groove 10 is lower than the surface of the body 2 on the tail side of the groove 10, the rainwater blown up on the surface of the body 1 on the head side of the groove 10 flows on the introduction surface 13. It will hit the damming surface 12. Then, since the angle formed by the damming surface 12 and the introducing surface 13 is formed to be an acute angle, the rainwater flowing on the introducing surface 13 is prevented by the damming surface 12
It takes a very large amount of energy to get over. Therefore, most of the rainwater flowing on the introduction surface 13 cannot move to the surface of the main body 1 on the tail side of the groove portion 10,
It flows through the groove 10 along the dam surface 12 and is discharged from the lateral side of the crosspiece 1A.

Therefore, most of the rainwater blown up from the head side to the butt side on the surface of the main body 2 on the head side of the groove portion 10 can be reliably stopped by the damming surface 12, so that it enters the groove portion 10. It is possible to prevent rainwater from flowing to the surface of the main body 2 on the hip side of the groove 10. That is, since the amount of rainwater flowing to the hip side water return 3 and the auxiliary water return section 20 can be reduced by the groove section 10, the water return effect in the hip side water return 3 and the auxiliary water return section 20 can be improved. Of.

[0025]

According to the invention of claim 1, it is possible to improve the water repelling effect in the tail side water repelling. Also, the roof can be made larger than the actual roof area. Further, the appearance of the roof becomes beautiful, and a characteristic appearance different from that of the roof in which a conventional roof tile is used can be exhibited. According to the invention of claim 2, since the introduction surface of the groove is lower than the body surface on the rear side of the groove, rainwater blown up on the body surface on the head side of the groove can be dammed by the damming surface. The flow of rainwater that blows up can be weakened at the groove. Moreover, it is possible to prevent rainwater that has entered the groove from flowing to the surface of the main body on the tail side of the groove. According to the invention of claim 3, since the angle formed between the damming surface of the groove and the introduction surface is an acute angle, rainwater blown up on the body surface on the head side of the groove can be dammed surely by the damming surface. Therefore, it is possible to reliably prevent the rainwater that has entered the groove from flowing to the body surface on the rear side of the groove. According to the invention of claim 4, since the bottom portion is formed into a flat surface, it is possible to prevent rainwater, dust and the like from accumulating in the groove portion. According to the invention of claim 5, since the auxiliary water return part is recessed from the main body surface, the height from the upper end of the butt side water return part to the bottom of the auxiliary water return part is high.
Therefore, even if the rainwater blows into the auxiliary water return part, the rainwater does not reach the upper end of the tail side water return, so the rainwater does not penetrate from between the roof tiles above and the upper end of the bottom side water return, and a rain leak occurs. Can be prevented. According to the invention of claim 6, the auxiliary water return portion is recessed from the surface of the main body, and the inclined surface of the auxiliary water return portion is inclined downward from the end on the hip side water return side when the roof tile is attached to the roof. Since it is formed, it is possible to enhance the drainability of the rainwater collected in the auxiliary water return section. According to the invention of claim 7, since the auxiliary water return section is also provided on the lateral side of the crosspiece, and the height from the upper end of the side water return section to the bottom of the auxiliary water return section becomes high, the rainwater Even if the water is blown in from the side, it is possible to prevent rainwater from leaking because the rainwater does not infiltrate between the roof tiles above and the upper ends of the side drains.
