Abstract

PROBLEM TO BE SOLVED: To provide a plain roof-tile which can suppress intrusion of rainwater from a gap between plain roof-tiles mutually adjacent to each other in the lateral direction. SOLUTION: As rainwater which has intruded from a narrow gap presents between mutually adjacent plain roof-tiles or has been received by a collar part 14 is flowing downward in the vertical low direction due to a gradient of a roof, an interval between a perpendicular wall face in the vertical low direction 28 and a guide face 29 of a water collecting projection 30 is set narrow so that the rainwater is guided to the perpendicular wall face in the vertical low direction 28. At this time, a portion where the rainwater concentrates is generated from a point where the interval between the perpendicular wall face in the vertical low direction 28 and the guide face 29 of the water collecting projection 30 becomes the narrowest part through its upstream, the portion is strongly pushed by the force of the concentrated rainwater flowing from the upstream and swollen, the interval is covered with the rainwater, and intrusion of the rainwater from the interval between the plain roof-times mutually adjacent in the lateral direction can be suppressed. That is, further intrusion of the rainwater can be prevented by using the rainwater having intruded from the interval.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat tile that has a flat shape as a whole.

[0002]

2. Description of the Related Art In general, a tile material used for roofing is provided with a collar provided on one of both sides in the row direction and inserted under an adjacent tile, and a tile material on both sides in the row direction. A cross section provided on the other side and overlapped on an adjacent tile, a butt section provided at an upper end in the column direction and inserted under the adjacent tile, and a lower end provided in the column direction And a head that is overlapped on an adjacent tile. For example, an S-shaped roof tile is formed such that a semicircular recess and a projection are connected to each other to form an S-shaped cross section, and a convex bar is overlapped on the other end of the horizontally adjacent roof tile. It has become. The above-mentioned tiles are usually placed on the ground under the roof through soil or directly, and are sequentially arranged so as to be aligned in the column direction and the row direction.

[0003] By the way, a flat part forming a substantially flat form, a collar protruding from one of both side parts in the row direction of the flat part and inserted under an adjacent tile, and a flat part formed by the flat part A flat-format tile having a cross section protruded from the other one of the two side portions in the row direction and overlapped on a collar section of an adjacent tile is a cross section of the collar section and a cross section of the adjacent tile. Are arranged so as to overlap with each other, and the flat portion does not overlap with the horizontal portion of the tile, so that, for example, as shown in FIG. 2, the tiles can be overlapped so that the row direction is substantially flat. The appearance of such roofs with plain tiles has been widely used to harmonize with houses of various architectural styles.

[0004]

In the meantime, the flat tile has a slight gap between its crosspiece and the flat part of the adjacent tile. Even if rainwater enters the gap if it is a normal rainfall, the infiltrated rainwater is received by the collar and further flows to the lower tile stacked under the roof of the tile, If the amount of rainfall far exceeds the amount of rainfall, rainwater that enters through the gap and is received by the collar may overflow from the collar and flow into the ground under the roof.

The present invention has been made in view of the above circumstances, and an object of the present invention is to suppress the intrusion of rainwater from a gap between flat tiles adjacent to each other in a row direction. To provide flat tiles.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the gist of the present invention is to provide a flat-format part having a substantially plain-format, and one of two sides of the flat-format part in the row direction. A collar portion protruded from and inserted under the adjacent tile, and a bar portion projected from the other of the two side portions in the row direction of the plain portion and overlapped on the collar portion of the adjacent tile. A flat tile having a butt portion provided at an upper end portion in the column direction and inserted under an adjacent tile, and a head portion provided at a lower end portion in the column direction and stacked on the adjacent tile; And (a)
A vertical vertical wall surface provided continuously in the vertical direction on the side of the flat portion on the side of the collar portion, and (b) projecting from the surface of the collar portion to guide rainwater to the vertical side of the vertical column surface. In order to achieve the above, a water drawing protrusion having a guide surface in which the distance from the vertical wall surface in the column direction becomes narrower from the upper side to the lower side in the column direction.

[0007]

In this way, the rainwater that has entered the gap between the flat tiles adjacent to each other and received by the collar is
As the roof flows downward in the column direction due to the slope, the space between the vertical wall surface in the column direction and the guide surface of the water drawing protrusion is narrowed, so that the water is guided toward the vertical wall surface in the column direction. At this time, the flow of the rainwater concentrates from a wide place to a narrow place, that is, a part where the rainwater concentrates from the point where the interval between the vertical wall surface in the column direction and the guide surface of the water drawing protrusion is the narrowest to the upstream side thereof. The concentrated rainwater is strongly pushed by the momentum of the rainwater flowing from the upstream side and swells, so that the gap is filled with the rainwater. Rainwater intrusion can be suppressed.
That is, it is an advantage of the present invention that it is possible to prevent further intrusion of rainwater by utilizing rainwater that has already intruded from the gap.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a flat tile according to an embodiment of the present invention.

FIG. 1 is a perspective view of a flat tile 10. The flat-format tile 10 has a substantially flat-format or flat-plate-shaped flat-format portion 12 and a collar portion protruding from one of both sides in the row direction of the flat-format portion 12 and inserted under an adjacent tile. 14, a cross section 16 protruding from a side of the horizontal direction of the plain section 12 that is not on the side of the collar section 14 and overlapped on an adjacent tile collar section 14, and an upper end section in the column direction. A butt portion 18 is provided and inserted under an adjacent tile, and a head portion 20 is provided at a lower end in the column direction and overlaps the adjacent tile.

The butt portion 18 has a butt side wall 22 extending along the edge thereof and projecting upward in the vertical direction with respect to the substantially flat surface of the flat portion 12. A head side wall 24 that is continuous along the edge protrudes downward in the vertical direction with respect to a substantially flat surface of the flat portion 12. When the flat tile 10 is overlapped with the adjacent flat tile 10 on the lower side in the column direction, the head side wall 24 becomes the upper flat tile 10.
In order to eliminate a gap between the head 20 and the buttocks 18 of the lower flat tile 10. Furthermore, when the plain tiles 10 are stacked for stock or the like, an engaging projection (not shown) protruding from the rear surface of the butt portion 18 is fitted into the butt side wall 22 to be hooked on the roof. Fitting groove 26
Is provided.

Between the flat portion 12 and the collar portion 14, on the side of the flat portion 12 on the side of the collar portion 14, there are provided vertical vertical wall surfaces 28 continuous in the column direction.
At a predetermined height from the collar portion 14, it projects vertically above the flat surface of the collar portion 14 at a height equal to or greater than the thickness of the crosspiece 16.

In order to guide the rainwater flowing into the collar portion 14 toward the vertical wall surface 28 in the column direction, the surface of the collar portion 14 is formed with the vertical wall surface 28 in the column direction from the upper side to the lower side in the column direction. Three water drawing ridges 30 each having a guide surface 29 positioned so as to be narrower are provided. It is preferable that the water ridge 30 is higher as long as it does not hit the back side of the crosspiece 16 (the side facing the flat surface of the collar 14). In the present embodiment, the height is about 1/4 of the height of the vertical wall 28 in the column direction, the length is about 1/4 of the length of the vertical wall 28 in the column direction, and the width of the collar 14 is Each is configured as a rectangular parallelepiped of about 1/6 with respect to the width in the direction,
A surface of the water drawing ridge 30 that faces substantially parallel to the vertical wall surface 28 in the column direction is a guide surface 29. In addition, on the upper edge of the collar 14 and the edge opposite to the vertical wall surface 28 in the column direction, in order to prevent rainwater flowing into the collar 14 from flowing down to the lower ground of the roof, A water return protrusion 32 is provided at a predetermined height which is substantially equal to or slightly lower than the water draw protrusion 30.

In the flat tile 10 constructed as described above, the cross section 16 overlaps the collar 14 of the adjacent flat tile 10 in the row direction, and the head 20 has the head 20 adjacent to the lower side in the column direction. Roof 10
It is placed directly on the inclined base surface of the roof (not shown) via soil or directly so as to overlap with the butt portion 18. FIG. 2 shows an example in which the flat-format tiles 10 are placed in such a manner.
An example is shown in which the arrangement is such that a zigzag roof is displaced in the row direction by half a sheet.

FIG. 3 is an end view of a section taken along line AA of FIG. Even if the tiles are arranged in a zigzag pattern as shown in FIG. 2, or if the tiles are stitched in which the flat tiles 10 vertically adjacent to each other are arranged in parallel, rows are arranged on the collar 14 in a row. In the form in which the cross sections 16 of the flat tiles 10 adjacent to each other in the direction are overlapped, the cross sections 16 of the flat tiles 10 and the flat sections 12 of the flat tiles 10 adjacent to each other in the row direction of the flat tiles 10 are formed. There is a slight gap B between, and rainwater enters through the gap. The infiltrated rainwater is received by the collar portion 14 and flows to the surface of the flat tile 10 located on the lower side in the column direction.

FIG. 4 is a view of a part of the collar portion 14 and the flat format portion 12 as viewed from above in a direction perpendicular to a surface of the flat format portion 12 forming a substantially flat shape. The rainwater that has entered the small gap B shown in FIG. 3 and received by the collar portion 14 flows downward in the column direction due to the slope of the roof, and guides the vertical wall surface 28 in the column direction and the drainage ridge 30. Since the distance from the space 29 is small, the space 29 is guided toward the vertical wall surface 28 in the column direction as shown by the arrow. As a result, the amount of rainwater flowing to the water return protrusions 32 decreases, and the rainwater flows
In addition to being able to prevent flowing to the ground surface beyond
The rainwater flow is concentrated from a wide place to a narrow place, that is, collected on the vertical wall surface 28 side, so that the vertical vertical wall surface 28 and the guide surface 2
The part where rainwater concentrates is formed from the point where the interval with 9 becomes narrowest to the upstream side, and the concentrated rainwater is strongly pushed by the momentum of the rainwater flowing from the upstream side and rises, as shown in FIG. As described above, the small gap B between the crosspiece 16 and the flat portion 12 of the flat tile 10 adjacent in the row direction is filled, and further infiltration of rainwater is suppressed.

FIG. 5 illustrates the effect of the present invention.
FIG. 2 is a side view of the plain tile 10 viewed from the side of the collar 14 in the row direction. The hatched part shows one flat tile 1 as an experiment.
When water flows from the upper end in the column direction of the collar portion 14 in a state where it is inclined at 0, the vertical wall surface 28 in the column direction gets wet with water. The water is guided and flows by the water ridge 30, and the water ridge 30 and the vertical vertical wall surface 2 are formed.
The water swells up to a position higher than the height of the water ridge 30 with the position at which the distance from the ridge 8 is narrowest at the top. Since the water pressure increases as the amount of water flowing through the collar 14 increases,
The climax of this water is high. Therefore, the greater the amount of rainwater that enters through the small gap B between the crosspiece 16 and the flat part 12 of the flat tile 10 adjacent in the row direction and is received by the collar part 14, the more the rainwater becomes. However, the greater the amount of rainwater received by the collar portion 14, the more effectively the space B can be closed and the further intrusion of rainwater can be suppressed. .

As described above, according to this embodiment, the rainwater that has entered the gap B between the adjacent flat roof tiles 10 and received by the collar portion 14 flows downward in the column direction due to the gradient of the roof. As the distance between the vertical wall surface 28 in the column direction and the guide surface 29 of the drainage ridge 30 becomes narrower, it is guided toward the vertical wall surface 28 in the column direction. At this time, the flow of the rainwater is concentrated from a wide place to a narrow place, that is, the rainwater flows from the point where the interval between the vertical wall surface 28 in the column direction and the guide surface 29 of the drainage ridge 30 becomes the narrowest to the upstream side thereof. A concentrated portion is formed, and the concentrated rainwater is strongly pushed by the momentum of the rainwater flowing from the upstream side to swell, so that the gap B is filled with the rainwater. Intrusion of rainwater from the gap B between them can be suppressed. That is, according to the present embodiment, it is possible to prevent further intrusion of rainwater by using rainwater that has already intruded from the gap B.

While the embodiment of the present invention has been described with reference to the drawings, the present invention can be applied to other embodiments.

For example, in the above-described embodiment, the drainage ridge 30 has a height of about １ ／ of the height of the vertical wall surface 28 in the column direction and a length of the vertical wall surface 28 in the column direction. The width is about 1/4, and the width is about 1/6 of the width of the collar 14 in the row direction, and three water ridges 30 are provided. The shape and the number thereof are not limited to the above. For example, one or two or four or more water drawing ridges 30 may be provided, the overall shape may be an arc instead of a rectangular parallelepiped, and the height, width, length, The position can also be changed. In short, it is only necessary to guide rainwater toward the vertical wall surface 28 in the column direction by decreasing the distance from the vertical wall surface 28 in the vertical direction toward the lower side in the column direction.

In the above-described embodiment, the water ridge 30 having a uniform cross section in the longitudinal direction functions as the water ridge, but the water ridge has a non-uniform longitudinal cross section. You may. Other shapes, such as a shape in which the cross-sectional area increases toward the lower side in the column direction, may be used as long as the protrusion has even the guide surface.

In the above-described embodiment, the guide surface 29 is
Although it was perpendicular to the surface of the collar 14, if the rainwater was collected on the vertical wall surface 28 side, the collar 1
4 may be inclined with respect to the surface. Guide surface 2
9 has a uniform height, but the height need not be uniform.

Further, a flat recess may be formed at the center of the plain portion 12.

The above is merely an embodiment of the present invention, and the present invention can be variously modified without departing from the gist thereof.
