【考案の詳細な説明】 産業上の利用分野 本考案は、小屋裏の結露防止構造に関する。[Detailed explanation of the idea] Industrial applications The present invention relates to a structure for preventing condensation in an attic.
従来の技術
近年、屋根葺材の下地として、アスフアルトル
ーフイングのような防水性にすぐれた下地材が使
用されている。BACKGROUND ART In recent years, base materials with excellent waterproof properties such as asphalt roofing have been used as base materials for roofing materials.
考案が解決しようとする問題点
しかしながら、従来使用されている防水性下地

る。 In this case, if you install a ventilation hole in the ridge of the roof, the ventilation capacity to the outside of the roof will increase, and the moisture in the attic will dissipate to the outside with the air, which will prevent condensation to some extent, but rain and snow will There is a risk that the air will blow in through the ventilation opening, making it difficult to adopt it immediately.
本考案は、以上のような問題点を解決すること
を目的とする。 The present invention aims to solve the above problems.
問題点を解決するための手段
本考案は、屋根２の棟部２ａに透湿・防水性下
地材９を設けて、瓦等の屋根葺材１１で覆つたこ
とを特徴とする。Means for Solving the Problems The present invention is characterized in that a moisture-permeable/waterproof base material 9 is provided on the ridge portion 2a of the roof 2 and covered with a roofing material 11 such as a tile.

Moisture inside 4 is radiated to the outside air through a moisture permeable/waterproof base material 9.
実施例
以下、本考案に好適な一実施例を図面に基づい

る。 In the figure, reference numeral 1 indicates a roof truss constituting a roof 2, which extends over the left and right walls 4, 4 of a building 3. Above the two upper chord members 6, 6 disposed diagonally downward from the central apex 5 of the roof truss 1, there are purlins 7, 6 disposed perpendicular to each upper chord member 6.
7... has been constructed. Roofing boards 8, 8 are provided on top of these main buildings 7, 7, respectively.
A moisture-permeable/waterproof base material 9 and a normal waterproof base material 10 are laid on the sheath boards 8, 8 so as to cover the entire surfaces of these sheath boards 8, 8.

かれている。 One moisture-permeable/waterproof base material 9 is placed near the ridge 2a of the roof 2, and extends across the top 5 of the roof truss 1 in the direction of the eaves 2b of the roof 2. This moisture permeable/waterproof base material 9 is as follows:
For example, a suitably treated nonwoven fabric is used. The other waterproof base material 10 is the moisture permeable/waterproof base material 9.
are arranged from each side edge portion to the eaves portion 2b. As this waterproof base material 10, a conventional product such as asphalt roofing is used, for example. Small-shaped roofing materials 11, 11, such as roof tiles, are placed over the moisture-permeable/waterproof base material 9 and the waterproof base material 10 so that moisture can pass through the inside and outside of the roof 2.
また、屋根トラス１の下弦材１２の下側には天
井１３が設けられている。 Further, a ceiling 13 is provided below the lower chord member 12 of the roof truss 1.
この天井１３と前記屋根２との間に形成された

散され、該小屋裏１４の結露が防止される。 Due to the structure, the temperature of the air in the attic 14 formed between the ceiling 13 and the roof 2 tends to be higher near the ridge 2a of the roof 2 than in other places.
Therefore, a large amount of moisture gathers and stagnates near the ridge 2a. When a humidity difference occurs between the air in the attic 14 and the air outside the roof 2, the moisture in the attic 14 passes through the moisture-permeable and waterproof base material 9 provided in the ridge 2a. The dew is then dissipated into the atmosphere, and condensation in the attic 14 is prevented.

By installing a waterproof base material, moisture is dissipated into the atmosphere through this breathable and waterproof base material, making it possible to prevent condensation in the attic without the need for a special ridge ventilation system. It is something. Furthermore, even though moisture-permeable and waterproof base materials are expensive, they are only applied to the ridge of the roof instead of conventional waterproof base materials, which not only reduces material costs but also reduces construction costs. can also be done easily. Furthermore, since the waterproof function is maintained, there is no need for special rain protection.
