Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is based on the idea that when roof tiles are placed on a roof, tiles that are lined up horizontally are on the same plane. Concerning improvement of plate tiles.

[Conventional technology]

A roof covered with flat tiles has a very clean and beautiful surface with few irregularities. Becomes a design. Ordinary roof tiles that are most commonly used today, such as S-type slate Or, in the case of Japanese roof tiles, the overlapped part with the adjacent roof tiles has a chevron shape. Therefore, this Roofs covered with tiles such as these have ridges that extend vertically at regular intervals. This ridge It has a unique design, with a beautiful roof covered with Japanese-style tiles. Ma In addition, these protrusions also have the effect of preventing rain leaks. That is because strong wind and rain are moving along the roof. This is because it prevents the water from flowing sideways.

0003 However, a feature of flat tiles is that they do not have these ridges, which gives them their unique simplicity. The design of the roof has been realized. For this reason, flat tiles are exposed to strong wind and rain blowing sideways. It has the disadvantage that it is prone to leaking if it is exposed. When strong wind and rain blow sideways , rain flows horizontally along the surface of flat tiles. Like S-shaped slate tiles, weirs occur at the peaks. Unstoppable rain gradually increases in volume as it flows sideways, preventing rain from leaking from the boundaries. It becomes easier to wake up.

0004 In order to solve this drawback, a flat tile with protrusions on both sides and the upper edge of the tile body was developed. (Utility Model Publication No. 51-44573). This flat tile has multiple shapes on the upper edge. There are ridges. In addition, both sides of the protruding strip are bent to extend downward. place However, when flat tiles with this structure are actually blown onto a roof, they are blown upward from the sides. It is easy to cause leaks due to wind and rain. It is a ridged line provided in the vertical direction. However, it is not possible to effectively prevent the amount of rainwater from increasing as it flows sideways. It is the body. In addition, to the extent that both sides of the protruding strip provided on the upper edge are bent downward, It is not possible to reduce the energy of rapidly flowing rainwater, and it violently hits the lap area. They invade and cause rain leaks.

[0005] The inventor developed a flat tile structure that prevents leakage from wind and rain flowing sideways (actually Publication No. 2-125113). This flat tile is protected by wind and rain that blows up sideways. In order to prevent rain leakage, the upper edge and the wrap part have a unique structure.

[0006]

[Problem that the idea aims to solve]

However, flat tiles with these structures allow the amount of water to increase as rainwater flows horizontally. It is not possible to effectively prevent this from occurring. As a result, heavy rain falls There was a drawback that the problem of easy rain leakage could not be solved.

[0007] This invention was developed with the aim of resolving this drawback. The important purpose of the invention is to forcefully divert rainwater that flows sideways, so that the amount of water gradually increases. The purpose of the present invention is to provide a flat tile that can prevent water leakage and minimize rain leakage.

[0008]

[Effect of the idea]

With almost no exceptions, the roof tiles currently in use are useless no matter how much rainfall there is. There is no leakage in windy conditions. However, in reality, along with the rain When the wind blows, it is extremely difficult to design a structure that will not leak. especially, It is extremely difficult to prevent flat tiles from leaking in horizontal wind and rain. flat plate As mentioned earlier, roof tiles have no unevenness, so rainwater can easily flow sideways.

[0024] The flat tile of this invention has a corner at the boundary between the main body and the lap part, and at the corner of the main body. A groove is provided. Furthermore, the bottom of the corner groove is higher than the top of the lap part. It is shaped like this. Flat tiles with this structure do not have peaks when placed on a roof. This allows you to create a clean and beautiful design just like traditional flat tiles. Momokawa It can minimize the leakage of wind and rain that blows forcefully from the side. That's the roof When the roof is covered, the corner grooves provided in the main body and lap part create drainage channels. It is. Water gutters installed on the roof at regular intervals force some of the rainwater to flow sideways. to prevent the water volume from increasing gradually.

[0025] By the way, it is possible to create vertical grooves on the top surface of the main body of flat tiles to divert rainwater. It is. However, the amount of water that can be diverted by the vertical grooves in this area is small, and a large amount of water can be diverted. Can't solve rain leaks when it rains. Vertical grooves can increase the amount of water diverted by making them deeper. Can be done easily. However, if a deep vertical groove is provided in the main body, it will easily break from this part. This has the disadvantage that the strength of the flat tile is significantly reduced. For this reason, in reality, flat tiles The vertical grooves should be designed to be as shallow as possible so as not to reduce the strength of the structure. vertical groove The cross-sectional area can be increased by widening the width. However, the wide longitudinal groove The disadvantage is that wind blows in and blows rainwater away, making it impossible to effectively divert it.

[0026] In contrast, the corner grooves of this invention are designed to be deeper than the vertical grooves provided in the main body, making them stronger. This can reduce the drop in temperature. The boundary between the main body and the wrap is shown in Figure 2. This is because it can be easily reinforced. In addition, the flat tiles of this invention do not flow into running water grooves. By diverting some of the incoming rainwater to the wrap section, the amount of diverted water is significantly increased. There are features that can be used. Therefore, a considerable amount of rainwater flowing along the top surface of flat tiles is This prevents the water from being forcibly diverted to the water ditch and causing a significant increase in water volume. therefore, The flat tiles of this invention have a special feature that can minimize rain leakage during heavy rain with strong horizontal winds. There is a length. Also, when a roof is covered with flat tiles, corner grooves are exposed at the boundaries of the tiles, and there are many Features of roof tiles that can be used as an accent to decorate the roof beautifully can also be achieved.
