Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention mainly relates to an attic ventilation tile that can ventilate the attic of a house and prevent corrosion of roofing boards and the like due to dew condensation.

(Prior art) A roof made by covering roof tiles with airtight roofing boards has excellent waterproof and heat insulation properties, but is poor in ventilation properties. As a result, the humidity in the attic becomes high, causing dew condensation and cracking, which causes the wood to rot and significantly shorten the lifespan of the house, which is a major problem. Therefore, some systems have been developed in which a suitable number of ventilation holes are provided in the ridge tile, mendo tile, or tsugi tile itself to naturally ventilate the attic.

(Problems that the invention aims to solve) However, because conventional tiles of this type do not have an appropriate water-preventing function, rainwater may enter during rainstorms, there may be problems with the installation strength, and the water-preventing mechanism may not work properly. The problem was that it was too complicated and the cost was high.

(Means for Solving the Problems) The present invention solves the above-mentioned problems and allows sufficient ventilation of the attic without impairing waterproofness, and can be easily constructed and provided at low cost. This tile was completed for the purpose of attic ventilation; an appropriate number of ventilation notches are provided on the upper edge of each of the opposing side doors connected by a connecting part, and a vertical rainwater circulation section is provided between the side doors. It is characterized by:

(Embodiment) Next, the present invention will be described in detail with reference to the illustrated embodiment. Reference numerals 1 and 1 are mento doors connected by a connecting portion 2, and each mento door 1 has a plurality of Ventilation notches 3 are arranged at required intervals.
Reference numeral 4 denotes a vertical rainwater distribution section provided between the side doors 1, 1, and the rainwater distribution section 4 in the illustrated embodiment is a girder plate-like section that is entirely stretched between the side doors 1, 1. A suitable number of through-holes are provided in the connecting part 2, but if the connecting part 2 is made into a plurality of girder-shaped holes, the space between the connecting parts 2 and 2 is used as the rainwater distribution part 4. do it. In the illustrated embodiment, it is preferable that the surface of the connecting portion 2 has the same slope as the roof slope during construction, so as shown in FIG. It has a tapered shape. Moreover, this connecting portion 2 is connected to the first
As shown in the first embodiment shown in FIGS. There is one near the upper end of the door 1, the former has an H-shaped cross-sectional shape in the middle part, the latter has an inverted gutter-shaped cross-sectional shape, and the connecting part 2 of the latter has a side door 1. It has a groove that matches the ventilation notch 3.

(Function) As shown in FIG. 5, for example, as shown in FIG.
3 and when tile roofing is done by the usual method, the top of the ridge is made into a roof ridge with a ventilation hole 14 leading to the attic 16, and the attic ventilation according to the present invention is installed near the top of the roof tiles 15, 15 near the ridge. The tiles are placed so that the ventilation notches 3 provided on the upper edge of each of the side doors 1, 1 are communicated with the ventilation holes 14, and the tiles are inserted through the ventilation holes 14 or a separately provided wire insertion hole. If the roof tile 17 and ridge tile 18 are fixed with a wire or the like, and the ridge roof tiles 17 and ridge tile 18 are fixed, the mento doors 1, 1 connected by the connecting part 2 will have the same function as the conventional mento tile. In addition to this, it is maintained in an extremely stable state and has excellent strength. Moreover, the warm air rising into the attic is ventilated through the ventilation holes 14 and the ventilation notches 3 on the upper edge of the side door 1, and the humidity in the attic 16 does not become high, eliminating condensation and stuffiness. Corrosion will not shorten the lifespan of the house. In addition, since the ventilation notch 3 is provided only on the upper edge of the facing side doors 1 and 1 and is covered by the roof tiles 17, normal rain does not enter into the ventilation hole 14 side. , even if the air blows into the ventilation hole 14 side, a vertical rainwater circulation section 4 is provided between the side doors 1 and 1, which are connected at the connection section 2. There is no risk of water flowing into the attic or flooding the attic.

(Effects of the invention) As is clear from the above description, the present invention allows hot air and humidity that accumulates in the attic to rise through the ventilation holes in the ridge.
Since it is radiated outside through the ventilation notch on the upper edge of the door, the moisture in the room does not rise and stay in the attic and become hot and humid, and this does not cool down and condense, which can shorten the life of the building. In addition, since hot air does not get trapped in the attic, it is possible to avoid a hot and humid living environment in the summer.Furthermore, it is compatible with the ancient tile roofing method, so it does not have any disadvantages in closing the rain. It requires less construction work, has various advantages such as being able to prevent small animals such as rats from entering through the ventilation area, and not impairing its waterproof and insulation properties. Both have extremely great practical value.
