Description

[Detailed explanation of the idea] This invention relates to a tiled roof.

In the case of a conventional tiled roof, as shown in Fig. 1, rafters 23 are placed on top of a plurality of main buildings 21, and roofing boards 26 with roofing 25 applied to the rafters 23 are placed over the entire roof surface. Since the roof tiles 24 are installed on top of the roofing boards 26, the gaps 27 between the roof tiles 24 and the roofing boards 26 are narrow, and the gaps 27 between the roofing tiles 24 and the roofing boards 26 are covered with a heat insulating layer. It had almost no function. In addition, since each void 27 is independent, the tile 2
Air circulation on the back side of 4 was poor. For this reason, if an asbestos cement tile or the like with relatively high hygroscopicity is used, when the tile 24 is heated during the day, water vapor will be released from the front and back of the tile 24, and the water vapor released from the surface. Although this is a good thing because the water vapor is released into the outdoor air, there is a problem in that the water vapor released from the back side remains in the gap 27 and condensation occurs on the roofing 25.

The purpose of this invention is to solve these conventional problems.The surface of the tile has excellent air permeability and drainage, and the back side of the tile has sufficient air gaps to improve insulation. The purpose of the present invention is to provide a tiled roof in which construction work is facilitated by increasing the degree of freedom in the installation direction of heat insulating plates disposed on the back side of the tiles.

Hereinafter, embodiments of the present invention will be described based on the drawings. In this embodiment, as shown in FIGS. 2 and 3, insulation boards 2 are placed on a plurality of main buildings 1 over the entire roof, rafters 3 are placed on top of the insulation boards 2, Further, tiles 4 covering the entire surface of the heat insulating board 2 are directly installed on the rafters 3 with nails. The heat insulating board 2 is made of a synthetic resin foam with closed cells and a waterproof surface, and the surface of the insulating board 2 has drainage grooves 6 running in one direction diagonally intersecting the roof slope. It is carved across tile 3 so that rainwater that has seeped into tile 4 can easily flow toward the eaves.
Since the surface of the insulation board 2 is waterproofed,
This makes it possible to improve waterproofness compared to the case of using roof boards. Further, since the drain groove 6 crosses the rafters 3, the spaces partitioned by the rafters 3 communicate with each other via the drain groove 6, and air can be circulated through the drain groove 6.

As mentioned above, the present invention is based on a heat insulating board that is installed on multiple main roofs, the upper surface of which is waterproofed over the entire roof surface, and the upper surface of which is cut with drain grooves running in one direction diagonally intersecting the roof slope. At the same time, rafters that run along the roof slope are placed on the insulation board so as to cross the drainage ditch, and tiles are placed on top of the rafters to cover the entire surface of the insulation board, spaced apart from the top surface of the insulation board. A space is created between the insulation board and the tile by placing rafters that run along the slope of the roof between the tiles and the insulation board, and then placing the tiles on top of the rafters. This allows air to circulate within this space. Additionally, tiles are generally not flat but have curved parts, but since there is a space between the insulation board and the tile, the back side of the tile comes into contact with the insulation board, and water flows in the drain groove. This does not impede the flow of air within the space. Furthermore, since the rafters are placed across the drainage grooves on top of the insulation board, which has drainage grooves running in one direction diagonally to the roof slope, the parts where the rafters are installed Drainage can also be carried out through drains under the rafters. In addition, since the drainage grooves pass under the rafters, ventilation is carried out between the insulation board and the tile in the area where the rafters are installed through the drainage grooves. In either case, breathability can be provided. That is,
A pair of adjacent spaces separated by rafters are communicated via a drainage groove, providing extremely excellent ventilation and drainage. However, in the present invention, not only can high insulation properties be obtained by the insulation board and the above-mentioned space, but also the air permeability and drainage performance are both extremely excellent as mentioned above. It works extremely well in achieving the goal of keeping the space between the tiles dry at all times (i.e., preventing condensation on tiles and roofing). Furthermore, since the drainage grooves are formed in one direction, it is possible to install them in either the vertical or horizontal direction by simply arranging the sides of the insulation board to match the roof slope. This has the advantage of making construction work easier because there is no need to think about this.
