Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ventilation structure for roof tiles in which ventilation holes cannot be made in the main ridge or corner ridge.

[Conventional technology]

Generally, in the case of a hipped roof without a gable as shown in Figure 6, it is not possible to provide a ventilation hole in the gable, so conventionally, as shown in Figure 7, a horizontal A ventilation opening 4 is provided in the nokiten 3 that protrudes from the roof to ventilate the attic 5.

This ventilation port 4 is arranged downward and is located in the closet 3 with poor ventilation, so there is a drawback that the attic 5 cannot be sufficiently ventilated. Especially in recent years, as insulation materials such as glass wool are often used in the attic 5, ventilation is even worse, making it easy for heat and moisture to get trapped, causing severe damage to the attic material. There was a drawback that the value decreased significantly.

In order to solve this problem, the present inventor installed at least two places on the main roof in the case of a hipped roof.
We developed and proposed a method for constructing ventilation holes (Japanese Patent Application No. 107029/1982, Japanese Patent Application No. 250162/1983).

As shown in FIGS. 8 and 9, a ridgepole 6 is installed horizontally at the top of the roof 1, and a plurality of rafters 7 are installed perpendicularly to each other at intervals. A roof plate 8 is attached to the roof plate 8.

At least two of the middle ridges 9 of this roof frame structure
After opening the through holes 10 at the locations, cover with tiles 11,
Along the main ridge 9 are roof tiles 12 and flat tiles 13. Further, a square cylinder 14 is passed through a through hole 10 formed in the roof plate 8. This cylindrical body 14 is the ninth
As shown in the figure, the cylinder body 14 is integrally attached through a curved flange plate 15, and the upper part of the cylinder body 14 is cut out in a chevron shape, and a butterfly valve 16 bent in an F-shape is rotatably supported here. ing. 17 is cylinder 1
It is a frame-shaped cover that surrounds the periphery of the butterfly valve 16, and has ventilation holes 18, 18 on both sides facing the butterfly valve 16.
is opened.

As shown in Figure 8, this ventilation structure is
Then, the flat tiles 13 and the round tiles 19 are sequentially roofed on top of the roof tiles, as shown in Fig. 10.
Externally, it will be in the same condition as conventional ridge tiles.

In the above-mentioned ventilation structure, moist air in the attic 5 rises to the main ridge 9, passes through the cylinder 14, is sucked through the upper opening by the action of a mist sprayer, and is rectified along with the wind in the direction of the arrow. It is efficiently discharged. Moreover, since the ventilation openings 18, 18 are provided in the well-ventilated main ridge 9, the attic 5 can be sufficiently ventilated, preventing rotting of the attic material due to heat and moisture and deterioration of the insulation performance of the insulation material due to moisture absorption. It can be prevented for a long period of time.

However, the above-mentioned ventilation structure can be constructed in the main ridge 9 where there is a space between the ridgepole 6 and the top of the roof plates 8, 8 through which the cylinder 14 passes, but it has been widely adopted in recent years. This method could not be applied to roof plate structures based on prefabricated panel combinations, or to structures where through-holes cannot be drilled through the cylindrical body in the main ridge or corner ridge, such as the corner ridge of a two-story house.

[Problem that the invention attempts to solve]

The present invention was developed in view of these points, and includes a roof plate structure using prefabricated panel combinations,
Even in structures where through-holes cannot be made in the roof panels of the main or corner roof, such as the corner ridge of the first floor roof of a two-story house, it is possible to effectively ventilate the attic without changing the appearance. This provides a ventilation structure for tiled roofs.

[Means for solving problems]

The present invention will be described in detail below with reference to the drawings.

Figures 1 to 4 show the case where it is attached to a prefabricated large ridge.

Figure 1 shows the duct 20, which is made of stainless steel plate, galvanized iron plate, etc., has a flat surface slightly smaller than the tile 11, a height that is approximately the same as or lower than the tile beam 21, and a lid with an open bottom. A ventilation hole 23 is formed by cutting and raising the upper end of the shaped main body 22.

Fig. 2 shows a prefabricated roof, in which grooved connecting members 24 are provided along the roof surface at predetermined intervals, and between the grooves 25, 25 panels with protrusions 2
6... are fitted together and connected together to form a roof plate 8. A waterproof sheet 27 is spread over the entire upper surface of the roof plate 8. This roof board 8 is
Since the connecting member 24 of the main ridge 9 serves as a supporting member, a through hole cannot be drilled in this portion. For this purpose, through-holes 10, 10 are drilled several tens of centimeters down on both sides from the main ridge 9, and the lid-shaped ducts 20, 20 shown in FIG.
3 are placed facing each other to form the state shown in FIGS. 2 and 3.

After this, as shown in FIG.
Attach it to the roof and start from the eaves side of the roof and gradually cover the roof upwards. Next, place the mendo noshi tile 12 along the main ridge 9,
Furthermore, the flat roof tiles 13 are stacked on top of this, for example, in three stages, while being alternately shifted. In this case, duct 2
In the area where tiles 0 and 20 are arranged, only one layer of side tiles 12 and flat tiles 13 with holes are stacked.

Next, the flange plate 15 to which the square cylinder body 14 shown in FIG.
Match 23. Thereafter, a frame-shaped cover 17 is placed so as to surround the cylinder 14, and the ventilation holes 18, 18 opened on the side surfaces thereof are made to face the butterfly valve 16 of the cylinder 14. In addition, a cover plate 2 is provided on the top of the cover body 17.
8 is attached to improve ventilation.

Next, the flat tile 13 and the round tile 19 are stacked on the cover 28 and assembled into the state shown in FIG. 4. In this case, the external appearance will be similar to the conventional one shown in FIG.

Therefore, in the above-mentioned ventilation structure, the attic 5 can be effectively ventilated through the through hole 10 opened near the main ridge 9 using the lid-shaped duct 20. Ventilation, which was previously impossible, can now be easily achieved without changing the appearance of the tiled roof.

FIG. 5 shows a case in which the roof plate 8 is directly attached and supported on the corner beam 30 that is inclined diagonally. Cannot drill holes. in this case,
A through hole 1 is located several tens of centimeters away on both sides from the corner ridge 29.
Holes 0 and 10 are opened, and lid-shaped ducts 20 and 20 shown in FIG.
are arranged to face each other. Also, the cylindrical body 14
uses a cylindrical type without a butterfly valve, and the other configurations are the same as in FIG.

In the above embodiment, the flange plate 15 to which the cylindrical body 14 is attached and the frame-shaped cover 17 surrounding the flange plate 15 are separate, but they may be joined together.

Further, although the duct 20 is shown as being installed on both sides of the main ridge 9 or the corner ridge 29, it may be installed only on one side. Further, the duct 20 is not limited to one in which the entire bottom surface is open, but may be one in which the bottom surface is partially opened corresponding to the through hole 10 of the roof plate 8.

[Effect of idea]

As explained above, the tiled roof ventilation structure according to the present invention can be applied to roof plate structures based on prefabricated panel combinations, roof plates of large ridges and corner ridges such as corner ridges of the first floor of two-story houses, etc. Even in the case of a structure in which through-holes cannot be opened, the attic can be effectively ventilated without changing the appearance.
