Description

[Detailed explanation of the invention] Purpose of the invention The conventional method for natural ventilation in the upper part of a room is to provide ventilation holes in the side walls above the ceiling, allowing air to flow in and out naturally through these holes. Although this prevents rainwater from entering the house, sufficient ventilation cannot be expected because the holes face to the sides. This project provides air circulation holes on the tops of the roof tiles and ridge tiles to ensure sufficient indoor ventilation, and also installs a water receiving plate under the hole in the ridge tiles to avoid direct intrusion of rainwater. The purpose is to do so.

Constituent action of the invention In this invention, a horizontally long ventilation hole 3 surrounded by a convex edge 2 is provided in the center of the roof tile 1, and a ridge tile 5 having a ventilation hole 4 on the top surface is placed on top of the tile. A rectangular tube 8 with a water-receiving curved plate 6 on the upper surface and window holes 7 on the four sides is positioned below the ventilation hole 4 of the ridge tile, and the bent lower end 8' of the tube is connected to the convex edge 2 of the ventilation hole. It is characterized in that the bent lower end 9' of a hanging plate 9, which is placed over the tube and protrudes downward from the lower edges of both front and rear plates of the cylinder, is hooked onto the lower hole edge of the ventilation hole 3. The indoor air A is radiated outward through the ventilation holes 3 in the roof tile, the window holes 7 in the rectangular tube, and the ventilation holes 4 in the ridge tile, and the outside air flows into the room through these holes. Thus, rainwater entering through the ventilation hole 4 of the ridge tile is received by the curved plate 6, flows along its upper surface, falls onto the tile, and flows out through the gap between the tile and the ridge tile. (Above arrows in Figure 1).

Effects of the invention Since the ventilation holes 4 are provided on the top surface of the ridge tiles, indoor dirty air can be dissipated more quickly and sufficiently through the ventilation holes 3 of the ridge tiles and the window holes 7 of the square tube than the ventilation holes. Since outside air flows in, natural ventilation is performed efficiently.

The air that flows through the space under the flat tiles on the roof along with the indoor air is dissipated through the holes in the roof tiles and ridge tiles, which provides an insulation effect during the hot season and lowers the indoor temperature. It is useful for

Ventilation removes as much moisture as possible from the attic, prevents the roof from rotting, and improves the durability of the building.

Rainwater passing through the ventilation hole 4 of the ridge tile is received by the curved plate 6 below and flows down to the outside from between the ridge tile and the roof tile, thereby preventing rainwater from entering the house. . Since the bent lower end 8' of the square tube was placed over the convex edge 2 of the ventilation hole, and the bent lower end 9' of the hanging plate 9 was hooked on the lower edge of the ventilation hole, the square tube was stabilized. It will not fall off the tile or be shaken. This project is extremely easy to manufacture and does not require a lot of construction costs, as it can be used as is by simply drilling holes in conventional ridge tiles and roof tiles.
