Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ventilation structure for a tiled roof, and particularly to a ventilation structure based on a base of a tiled roof.

BACKGROUND TECHNOLOGY In modern houses, the attic is covered with a waterproof sheet, and the openings in the walls are tightly sealed with sash, so the moisture generated inside the house cannot escape, and the wood is prone to rot. Therefore, as shown in Figure 6, some houses have a ventilation tube 50 inserted into the roof board 30, but in this case, the hole in the roof board is only large enough to insert the ventilation tube, so it is necessary to make a large opening. However, in order to provide sufficient ventilation, it was necessary to drill many holes, and accordingly, a large number of ventilation pipes had to be installed, making the construction extremely troublesome.

Problems to be solved by the invention The purpose of the invention is to solve the above-mentioned drawbacks associated with the arrangement of ventilation pipes, to ensure sufficient ventilation, and to prevent rainwater from entering with a simple structure. It's in the middle of the day.

Means for Solving the Problem The ventilation structure for a tiled roof according to the present invention has ventilation holes in the roofing board, and in the space between the roof tiles and the roofing board, the upper side of the ventilation board covering the ventilation hole is closed. It is fixed to the field board, and on the lower side of the ventilation board, there is an insect proofing plate between the ventilation board and the field board. It is characterized by the provision of a water stop groove.

How it works Humid air rising indoors is guided through ventilation holes in the roofing board into the space between the tiles and the roofing board, and then exhausted to the outside through the gaps between the tiles. On the other hand, wind containing raindrops from the outside enters the large space between the tiles and the roofing board through the narrow gap between the tiles and is decelerated, and is further decelerated by the water stop net before reaching the ventilation hole, and the raindrops are dispersed into the wind. separated from The separated raindrops, which have lost their speed, flow down the slope of the roof board and are discharged outside without flowing into the ventilation holes.

Embodiments Hereinafter, the present invention will be described with reference to the drawings.

First, explanation will be given with reference to FIG. On top of ridgepole 1〓2
Then, nail the roofing board 3 to this. Tile sill 4,
4, a ridge ventilation hole 5 and a plane ventilation hole 5' of sufficient size are made in the roof board 3, and a waterproof sheet 6 is pasted on the roof board 3. As shown, ventilation holes 5,
A ridge ventilation plate 7 is placed so as to cover 5' with a gap left therein.
Plane ventilation boards 7' are provided, and the upper sides of these ventilation boards are nailed to the roof board 3, and the lower sloped sides of the ventilation boards are installed for insect protection. A water stop net 8 is arranged between the roof board 3 and the roof board 3. Thereafter, the ridge beam receiving metal fittings 9 are nailed to the roof board 3, and the ridge beam 10 is attached thereto with nails 11.
Then, the tiles 13 are roofed over the roof board 3 via the tile beams 4, 4, and the shutters with the ridge tile 15 are coated with clay or mortar 14, and then the ridge tile 15 is covered, and the ridge beam 10 is waterproofed. Drive in the accessory nail 12 with packing to secure it. Note that both ends of the ventilation plates 7, 7' in the direction along the ridge are closed by plates.

Since the ventilation structure of the tiled roof according to the present invention is as described above, the indoor humid air passes through the ridge ventilation hole 5 and the plane ventilation hole 5', which have a sufficient opening area in the roofing board 3, to the roof tile 13. and the gap 16 between the roof tiles 15 and the roof tiles 3.
(FIG. 2) Alternatively, it is discharged to the outside through the gaps 16' between the roof tiles 13.

On the other hand, the wind containing raindrops that tries to enter the ceiling from the outside is first decelerated through the gap 16' between the tiles 13 to the large space formed between the ground tile 13 and the roofing board 3, and then further ventilated. Due to the resistance of the water stop net 8 in front of the holes 5, 5', the wind speed is further weakened and the raindrops are separated from the wind. Since the ventilation holes 5 and 5' are placed apart above the water stop net 8 so that these raindrops do not immediately flow into the ventilation holes 5 and 5',
Raindrops flow down on the slope of the field board 3 and are discharged to the outside.

If it is not possible to make a long distance between the ventilation holes 5, 5' and the water-stop net 8, use two water-stop nets to create a double layer, or fold one sheet of water-stop net as appropriate to create a double layer. It is also possible to use a material that has the same water-stopping effect as when it was used.

Referring to FIG. 3, it is a front cross-sectional view of a ridge showing the same configuration as FIG. 1 except that a door tile 14' is provided. Figure 4 shows the gaps 16 and 1 between tiles when the side tiles 14' of Figure 3 are installed.
FIG. Figure 5 shows a front sectional view of the corner ridge, which is almost the same as the front sectional view of the ridge in Figure 1, but raindrops that have entered between the ground tile 13 and the field board 3 flow down in a direction perpendicular to the plane of the paper. Therefore, the corner ridge ventilation plate 7'' that covers the corner ridge ventilation hole 5'' is simply bent at a right angle and is not inclined downward. Note that, as in the embodiments shown in FIGS. 1, 3, and 5 above,
If the ridge ventilation board 7 or the corner ridge ventilation board 7'' is configured to straddle the ridge or corner ridge and the two ridge ventilation boards 7 are integrated with the corner ridge ventilation board 7, rain leakage in the ridge and corner ridge can be prevented. This can be prevented more reliably.

Effects of the invention According to the invention, the area of the ventilation hole can be freely and easily increased as needed.
Adequate ventilation is easily provided and therefore corrosion of the wood due to moisture can be completely prevented. Also, even if rain hits the roof, it won't go around the ceiling, and it's insect proof. A water stop net can prevent rain from entering, as well as rats, mixed insects, snakes, etc. Furthermore, since the tiles themselves are constructed using a standard method, there is no unnatural appearance or design.
