Abstract

PURPOSE:To prevent temperature rise in each of rooms by providing air vents to the sides, the end parts of the sides or corners of the sides of a mendo-tile, a roof tile filling a gap between a ridge tile and plain roof tiles, and by exhausting hot air under the roof tiles to the outside through said air vents. CONSTITUTION:Air vents 1 formed of small apertures or notches connecting the outside with the inside of a mendo-tile 2, a roof tile filling a gap between a ridge tile and plain roof tiles, are provided to the sides, the end parts of the side or corners of the mendo-tile 2. Hot air in a space between plain roof tiles 3 and roofing materials is led through cavities 4 formed to the inside of overlapping of adjoining roof tiles 31 placed on the right and the left and formed by roofing materials extending from the edges of eaves to a ridge, and is further led to a space on the inside of the mendo-tile whereto the cavities 4 converge, and is finally exhausted to the outside through the air vents of the mendo-tiles 2.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method of preventing temperature rise in each room of a house, and a menedo tile having a vent for use in this method.

<Prior Art> Conventionally, roof tiles for the roofs of houses have been used and manufactured for the purpose of preventing rainwater from entering the interior of the house and quickly draining the rainwater.

In Japan, where there is a lot of rain, roof tiles play an important role.
Weather resistance, durability, heat resistance, and cold resistance are required, and various efforts have been made to ensure good drainage and avoid being blown away by strong winds, and have been perfected over the long history of Japanese architecture.

Tiles are generally heavy and the temperature of the tiles can become extremely high when the sun hits them in the summer. The structure had high floors, long eaves, verandahs, and extensive use of open shoji and sliding doors to improve ventilation. Because the roof tiles formed the base and had good insulation properties, even if the roof tiles themselves reached high temperatures, the living space of the house did not become too hot.

However, due to the rationalization of architecture, the clay that was traditionally used as a base material for tiles is now almost no longer used, and roofing materials are often used instead. However, since roofing materials do not have insulation properties, not only the roof tiles but also the roofing materials and roofing boards become hot, so the attic of the house becomes quite hot in the summer, and each room of the house is affected by this. As a result, it started to get hotter.

Therefore, today, many attempts are being made to lower the temperature in the attic and improve the living environment, such as by installing roof windows for ventilation or by installing special ventilation equipment.

<Problems to be Solved by the Invention> However, the above-mentioned countermeasures have the problem of requiring a considerable amount of cost and making it difficult to solve the problem. In addition, simply ventilating the attic does not directly prevent the roof tiles, roofing materials, and sheathing boards from becoming hot, so it cannot prevent the radiant heat radiated from the sheathing boards and is inefficient. Ta.

In order to solve such conventional problems, the present invention provides a ventilation function to the tiles themselves, which are roofing materials, to prevent the roof tiles, roofing materials, and roofing boards from becoming hot, and also to ventilate the attic. The purpose is to improve the livability of houses by improving their properties.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a side surface or an end or a corner of a side surface of a mendo tile (2) which is an IN of a tile used as a roofing material for a house. A ventilation hole (1) formed by a small hole or notch leading from the outside into the inside of the Mendo tile is provided in the part of the Mento tile, so that the Mendo tile itself has a ventilation function, and a Mendo tile having this ventilation hole is used. By doing so, hot air under the roof tiles is discharged outdoors, preventing a rise in temperature in the attic and promoting ventilation, thereby preventing a rise in temperature in each room.

Effect> According to the present invention having such a characteristic structure, the hot air between the roof tiles and the roofing material is absorbed by each adjacent roof tile.
The eaves, which is formed between the back side of the left and right shaped parts of the tiles and the base material, roofing material, leads to the inner space of the mento tile, where these cavities come together through a cavity that leads to the ridge. The air is discharged to the outside through the vents provided by the mento tiles, thereby preventing the roof tiles, roofing materials, and roofing boards from becoming hot due to solar heat, and creating a system that lowers the temperature inside the house.

In other words, the space created between the roofing material and the back side of the roof tile has a wave-shaped cross section, but the cavity formed by the crests of the waves, that is, the overlapping parts of adjacent roof tiles, occupies most of that space. Moreover, since it is continuous from the eaves to the ridge, it forms a kind of ventilation pipe that goes from the bottom to the top.

On the other hand, since the trough of the wave gently draws an arc toward the mountain, the air heated by the roof tiles and roofing materials, that is, the hot air, becomes less dense and lighter, and moves from the trough to the crest of the wave. Ascend to the vent pipe. Therefore, the hot air that has gathered in the ventilation pipes is guided through the ventilation pipes and rises further, reaching the interior space of the mento tiles that are installed continuously on the ridge, and is discharged to the outside through the ventilation holes provided in the mento tiles. It is. At the same time, it goes without saying that the hot air trapped in the attic is also ventilated to the outside.

The number of ventilation holes provided in one Mendo tile is 2 in total, one on each side of the Mendo tile, but since many Mendo tiles are used in one building, they are installed on all sides. The total area of the openings of the vents provided in the door tiles is large enough to exhaust the hot air.

If the roof tiles, roofing materials, and roofing boards do not become hot, the radiant heat from them will be reduced, making it difficult for the attic to become hot, and even if hot air is trapped in the attic, it will be ventilated outside. As a result, the attic will no longer get too hot, and the temperature in each room will also drop.

<Example> The details of the present invention will be described below based on an example shown in the drawings.

FIGS. 1(a) and 1(b) to FIG. 4 show one embodiment of the present invention.

The cross sections shown in FIGS. 1(a) and (b) are the roof tile (3) except for the part below the roof tile (3), as shown in FIG. The overlapping part with the adjacent roof tile (31), and the area above the mendo tile (2), is a cross section of the central part of the mendo tile (2) where the ventilation hole is located. Roof tiles (31
) are only partially shown.

In this embodiment, the vent hole (1) is located at the upper end of the center of the side surface of the mento tile (2), in other words, at the center of the corner between the side surface and the top surface of the mento tile (2).

As is well known, Sangawara is a common roof tile (3).
It has a wave-shaped cross section, and the valleys guide rainwater downstream, and the peaks overlap and connect with adjacent roof tiles (31), as shown in Figure 3. Below the portion where the roof tiles (31) overlap, a cavity (4) is formed that continues upward from the eaves to the ridge. Of course, the tile crosspiece (5) that prevents the roof tile (3) from shifting will protrude into the cavity fv4 (4), but this does not pose a particular problem for the hot air to rise in the direction of the arrow inside the cavity (4). , which can also be confirmed through experiments. Also, if necessary, if you cut out only that part of the tile beam (5) that protrudes into the cavity (4),
The rise of hot air within the cavity (4) becomes even more effective. The hot air passes through the air 1v4 (4) and reaches the internal space of the Mendo tiles (2), which are continuously installed above the ridge, and then through the ventilation holes provided in the Mendo tiles (2). (1) It is discharged as shown by the arrow. As shown in Figure 4, the assembled tile (6) is placed on top of the mendo tile (2) with the seam of the tiles shifted by half the tile, and the assembled tile (6) is placed just above the ventilation hole (1). This will create a seam between the tiles (6). The assembled tiles (6) have strings (
6a), and just below this string (61) there is a ventilation hole (1
), it becomes difficult for rainwater to enter the room through the vent (1). However, even if rainwater were to enter through the vent (1), the roof tile (3) is placed below the mendo tile (2), so this roof tile (3) would prevent rainwater from entering. Rainwater will be discharged outside.

In this example, the ventilation hole (1) is provided at the end of the mendo tile (2), so it is easy to manufacture, and the manufacturing cost is almost the same compared to a normal mendo tile. .

Figure 5 shows an example in which the ventilation hole (1) is located at the center of the side of the Mendo tile (2), and Figure 6 shows the location of the ventilation hole (1) by cutting out the corner of the Mendo tile (2). Although an embodiment is shown in which the tile is provided at the lower corner of the side surface of the mendo tile (2), modifications may be made without departing from the gist of the invention.

<Effects of the Invention> As is clear from the above detailed description, according to the present invention, a surface that has been conventionally used as a roofing material can be used without using any equipment that is required only for that purpose. By providing ventilation holes in the roof tiles, hot air under the roof tiles can be efficiently discharged to the outside of the house, thereby preventing the temperature rise in each room and improving the livability of the house easily and at a very low cost. We were able to make improvements.
