Description

[Detailed explanation of the idea] [Industrial application field]

This idea is related to flat tiles whose upper surface, or running water surface, is formed on the same plane as the horizontally adjacent tiles when installed on a roof, and is particularly designed to minimize rain leakage at the lap part with the adjacent tiles. The aim is to provide flat tiles that can reduce the amount of waste.

[Prior art]

Flat tiles have already been developed in which the overlapping parts of tiles that are laid horizontally in the same row do not protrude from the upper surface of the other parts. In other words, tiles in which tiles of the same level are laid on the same plane have been developed. Tiles with this structure have the disadvantage that they are more likely to leak from the overlapped portions than tiles such as thick slate tiles, which have chevron-shaped overlapped portions. Conventional roof tiles of this type have protrusions formed on the periphery of the top surface, or grooves are formed on the top surface of the tile to disperse rainwater, or protrusions are formed on the top surface to control the direction of rainwater flow. This prevents rainwater from flowing into the overlapping parts (Jikko Kosho 51
-43631, Utsuko No. 51-44573). However, these structures cannot completely prevent rainwater from flowing into the overlapping parts.
In addition, there was a drawback that rainwater flowing into the overlapped portions was likely to cause leakage. The reason why flat tiles with this structure tend to leak at the lap part is as follows. Rainwater flowing down from the upper flat tiles easily flows into the lap part of the lower tiles. Rainwater that has flowed into the lower level difference is blown upward by strong winds and overflows from the upper end of the lower level difference. A flat tile with rainwater protrusions provided at the upper end of the lower step has already been developed as a flat tile that eliminates this drawback (Utility Model Application Publication No. 7208, 1929).
A flat tile with this structure prevents the overflow of rainwater from flowing into the lower level difference with the rainstop ridges. Therefore,
It can effectively prevent rain leaks that occur under these conditions. However, conventional flat tiles have the disadvantage that they cannot eliminate rain leaks caused by the problem while maintaining the beautiful design unique to flat tiles. In other words, conventional flat tiles are designed to reduce the amount of rainwater flowing into the lap area, which is prone to leaks.
At the center of the front edge of the top, there was a convex part that diverted rainwater to both sides. This convex part is made into a wide skirt shape in order to sufficiently divert rainwater. The width of this protrusion is quite wide, 1/2 to 1/4 of the total width of the flat tile, and it has a very noticeable defect when it is covered with a roof. Therefore, although the lap portions of conventional flat tiles can be made on the same plane, the presence of these convex portions has the disadvantage that the entire roof tile cannot be made into a clean and beautiful flat surface. In other words, because flat tiles can have a completely flat wrap, they can create a roof with a simple aesthetic that is difficult to achieve with conventional thick slate tiles. It was necessary to form striations and grooves, and this was the reason why the unique simple beauty could not be achieved.

[Structure and purpose of this idea]

This device was developed with the aim of eliminating the drawbacks of conventional flat tiles.The important purpose of this device is to minimize leakage at the overlapping portion during times of strong winds and heavy rain, and to There is no need to provide protrusions or depressions on the surface to prevent rainwater from entering the joint, and the top surface can be completely flush with the flat tiles next to it when it is installed on a roof. The purpose of the present invention is to provide a flat tile that can realize an aesthetically pleasing roof.

[Means to achieve the purpose]

The flat tile of this invention has the following configuration. The entire surface of the running water surface 6 on the upper surface of the tile except for the upper edge portion is formed in a flat shape so that the tile has a flat and smooth design when it is covered on a roof.
One side of the running water surface 6 is provided with a lower step part 1 which is formed lower than the running water surface 6 and on which the upper part 2 of flat tiles to be roofed adjacently on the same level is placed. The level difference between the lower step part 1 and the running water surface 6 is equal to or almost equal to the thickness of the upper mounting part 2 so that the running water surfaces 6 of tiles that are laterally adjacent and laid on the same level are on the same plane. It is made. A blocking protrusion 8 is provided on the front edge of the tile so as to protrude from the lower surface so as to block the front of the rain stop protrusion of the flat tile placed on the lower level when the flat tile is placed on the roof. There is. A rainwater outlet 9 is provided at the end of the lower surface of the blocking protrusion 8 to prevent rainwater that has flowed into the lower step from flowing into the lap part.
In addition, the entire lower surface of the closing protrusion 8 except for the opening of the outflow port 9 is made flat. A rain stop protrusion 4 is formed on the running water surface 6 so as to protrude from the surface along the upper edge so that rainwater does not overflow from the upper edge. Furthermore, a rainstop protrusion 4 is provided on the upper edge of the lower step portion 1 as well, extending from the upper end of the water flow surface 6 toward the lower step portion so that rainwater flowing therein does not overflow. The rainstop protrusions 4 provided on the upper edges of the lower step portion 1 and the running water surface 6 are made so that their upper surfaces are at the same height. Additionally, a hook-shaped cutout 5 is provided at the upper corner of the water flow surface 6 on the opposite side of the lower step portion 1 . The hook-shaped cutout 5 is formed into a shape into which a rainstop protrusion 4 provided at the upper end of the lower step portion of the flat tile roofed adjacent to the same step is fitted.

[Preferred embodiment]

Hereinafter, embodiments of this invention will be described based on the drawings. However, the embodiments shown below are illustrative of a device for embodying the technical idea of this invention, and the device of this invention has different materials, shapes, and
The structure and arrangement are not limited to those shown below.
Various modifications may be made to the device of this invention within the scope of the claims for utility model registration. The flat tile shown in FIG. 1 has a planar running water surface 6 on its upper surface. The entire surface of the running water surface 6 except for the upper edge portion is made flat so that the running water surfaces 6 of the tiles on the same level are on the same plane when the roof is covered with flat tiles. When covered with a roof, the upper edge portion of the running water surface 6 is blocked by a blocking ridge 8 of a flat tile roofed on the upper level, as shown in FIG. In other words, the rainstop ridges 4 provided on the upper edge of the running water surface 6 and the front wall ridges 7 are hidden behind the lower surface of the upper flat tile when the roof is covered. In FIG. 1, on the left side of the running water surface 6, a lower step part 1 is formed, the upper surface of which is lower than the running water surface 6. The lower step part 1 is covered with a roof by placing an upper part 2 of a flat tile which is placed adjacent thereto. With the upper part 2 wrapped around the lower step part 1, the flat tiles laid on the same level have the upper surfaces of the running water surfaces 6 on the same plane, as shown in FIG. Therefore, the level difference between the lower level difference part 1 and the flowing water surface 6 is made to be the same as the thickness of the upper mounting part 2 overlaid on the lower level difference part 1. However, the running water surfaces 6 of flat tiles that are laid adjacent to each other on the same level may be laid on almost the same plane, so the difference in level between the lower step and the running water surface 6 is as follows.
It is also possible to make the thickness approximately equal to the thickness of the upper part. A running water groove 3 is formed on the upper surface of the lower step part 1 so as to extend vertically so that rainwater flowing therein flows down smoothly and is difficult to overflow. In the flat tile shown in FIG. 2, two running water grooves 3 are provided in the lower step portion 1. It is also possible to form more than two running water grooves 3. Further, the width of the lower step portion 1 is preferably determined to be 40 mm or more. A rainstop protrusion 4 is formed on the upper edge of the lower step portion 1. The upper end of the rainstop protrusion 4 is located on the same plane as the running water surface 6 so that the rainwater that has flowed into the lower step part 1 is not blown upward and overflows. On the opposite side of the lower step part 1, a hook-shaped cutout 5 is formed so that a rainstop protrusion 4 is fitted into the lower step part of a flat tile installed adjacent to the same step. The hook-shaped cutout 5 is provided at the corner of the upper edge of the upper part 2 which is superimposed on the lower stepped part 1 of the adjacent tile. A rainstop protrusion 4 is also formed on the upper edge of the hook-shaped cutout 5, and the rainstop protrusion 4 is formed at the same height over the entire upper edge of the flat tile. The height of the rainstop protrusion is preferably determined to be about 3 to 10 mm from the running water surface 6 and about 15 to 25 mm from the upper surface of the lower step part 1. In FIG. 1, the lower right side of the flat tile is formed to be somewhat thinner than the other parts, although not shown, and this thinner part is wrapped over the lower step part 1 and the running water surface 6. The tiles are laid flush with the adjacent tiles. A front wall protrusion 7 is provided on the running water surface 6 in front of and parallel to the rainstop protrusion 4. Front wall protrusion 7
is formed to be approximately equal to or slightly lower than the rainstop protrusion, and is designed so that the rainwater that has flooded between the rainstop protrusion and the front wall protrusion flows out to the center of the running water surface. Located on both sides of the surface. A closing protrusion 8 is formed on the lower surface of the front edge of the water flow surface 6 in a protruding manner. As shown in FIG. 2, this closing protrusion 8 is placed in front of the front wall protrusion 7 installed on the lower level, and closes off the front of the front wall protrusion 7. In the state shown in Fig. 2, the closing protrusion 8 is cut at the side to prevent rainwater that has entered the back side of the closing protrusion 8 from flowing down to the lap part of the flat tile roofed at the bottom. Outlet 9 is open. The outflow port 9 is located in front of the front wall protrusion 7 and opened so that rainwater on the flowing water surface 6 is not blown up by strong winds and invades the rear of the front wall protrusion 7. The flat tiles shown in Figures 1 and 2 have outflow ports located somewhat centrally from both ends of the running water surface.
The flat tile shown in Figure 3 has outflow ports 9 on both sides of the flowing water surface.
is provided. The outflow port 9 preferably has a width of 10 to 50 mm so that rainwater in front of the front wall protrusion can flow out smoothly.
The height is determined to be approximately 2 to 8 mm. As shown in FIG. 2, the lower surface of the blocking protrusion 8 is arranged along the running water surface 6 of the flat tile roofed on the lower level.
All other parts except the outlet are made in a straight line.

[Usage condition]

Figure 2 shows a roof covered with flat tiles. In this figure, the flat tiles are arranged horizontally with the lower step part 1 and the upper part 2 of the sides wrapped together.
Tiles that are laid horizontally and on the same level have a running water surface of 6.
are arranged completely on the same plane. The rainstop protrusion 4 of the lower step portion 1 is fitted into the hook-shaped cutout 5 of the adjacent flat tile. The horizontally arranged flat tiles are laid in a staggered manner in multiple horizontal rows, with the closing protrusions 8 placed on the running water surface 6 of the flat tiles laid on the lower level.

[Effect of the idea]

The feature of the flat tile according to this invention is that the entire upper surface of the adjacent tile is made flat, which effectively prevents rain from leaking at the lap portion. As a result, it is possible to create a roof that is extremely clear and simple and beautiful, which is unique to flat tiles, and it also has the extremely important feature of flat tiles, which is that it does not allow rain to leak easily. This feature is that the lower surface of the blocking protrusion provided along the lower surface of the upper end of the flowing water surface has a rain outlet on the side, and the entire area other than this outlet is made in a straight line. Realized. Flat tiles are laid in a staggered pattern, as shown in Figure 2. The flat tile roofed in this state allows the straight line part of the lower surface of the closing ridge to be aligned with the lap part of the flat tile roofed on the lower level, and the occluding ridge is the boundary between the lap parts of the flat tile. occlude the upper surface of the part. Further, an outflow port is opened on the side of the blocking protrusion, and the outflow port opened here is located in the center of the water flowing surface of the flat tile roofed at the lower level, and is away from the lap part. With the flat tiles laid in this state, rainwater that has entered the back side of the blocking ridges will flow down to the central part of the running water surface, without flowing down to the lap part of the flat tiles laid on the lower level. The reason why rainwater on the back side of the blocking protrusion does not flow down to the lap part of the flat tile is because the lower surface of the blocking protrusion blocks the lap part of the flat tile. For this reason, the flat tile of this invention can not only create a roof with an extremely beautiful design, but also achieve the feature of effectively preventing rain leaks, which is extremely important for tiles. In addition, in the flat tile of this invention, the rainstop protrusion formed on the upper edge of the running water surface extends to the upper edge of the lower step, and this A hook-shaped cutout is formed into which the rainstop protrusion at the upper part of the lower step portion can be fitted, and the protrusion is further extended to the periphery of this hook-shaped cutout. Therefore, even if the rainwater that has flowed into the lower step is blown up by strong winds, it can be smoothly drained without exceeding the rainstop ridges on the upper edge of the lower step. Therefore, rain leakage caused by strong winds and heavy rain can be greatly reduced. Furthermore, due to the property that rainwater does not leak even if rainwater enters the lower step, there is no need to provide a protrusion or the like on the boundary between the lower step and the flowing water surface to prevent rainwater from flowing in. As a result, the entire surface of the running water that appears on the surface of the roof when it is covered is made flat, resulting in a number of excellent effects such as creating a roof with the simple and sublime beauty unique to flat tiles.
