Description

この考案は換気棟に関し、特に家屋における小屋裏空間の自然換気を図るために屋根の棟部に取り取付けられる換気棟に関するものである。   The present invention relates to a ventilation building, and more particularly to a ventilation building attached to a ridge of a roof for natural ventilation of a back space of a house.

図7は、特許文献1に開示されている換気棟の概略構造を示す断面図である。   FIG. 7 is a cross-sectional view showing a schematic structure of a ventilation building disclosed in Patent Document 1.

図を参照して、換気棟61は頂点16から幅方向に向かって斜め下方に延びる板形状の傾斜部67と、傾斜部67の下方端部に接続され垂直下方に延びる垂直部68と、垂直部68の下方端から斜め下方に延びるフランジ部69とからなる棟板部材63を中心として構成されている。傾斜部67にはその長手方向に平行に延びる3つの換気口64が形成されている。棟板部材63の下面にはその中央部側に断熱材65が取付けられている。断熱材65の外方端部と換気口64との間の傾斜部67の下面には断面C字状の水切部材71が取付けられており、水切部材71の上方部には通気孔72が形成されている。又、水切部材71の傾斜面の上面には断面L字状の止水ガード74が取付けられている。止水ガード74の立上り部には排水孔75が形成されている。   Referring to the figure, the ventilation ridge 61 has a plate-shaped inclined portion 67 extending obliquely downward from the vertex 16 in the width direction, a vertical portion 68 connected to the lower end of the inclined portion 67 and extending vertically downward, A ridge plate member 63 composed of a flange portion 69 extending obliquely downward from a lower end of the portion 68 is formed as a center. Three ventilation holes 64 extending in parallel to the longitudinal direction are formed in the inclined portion 67. A heat insulating material 65 is attached to the lower surface of the ridge plate member 63 at the center thereof. A draining member 71 having a C-shaped cross section is attached to the lower surface of the inclined portion 67 between the outer end portion of the heat insulating material 65 and the ventilation port 64, and a vent hole 72 is formed above the draining member 71.

Therefore, when the fixing nails 36a and 36b are completely driven, the ventilation members 21a and 21b are maintained in the state as shown in the figure.

通気状態にあっては、矢印で示されているように屋根材28の中央部において捨水切33a,捨水切33bの間から上昇した空気は、換気部材21a,換気部材21bの各々の通気孔を介して内方側から外方側に通過する。通過した空気は傾斜部17a,傾斜部17bの各々に形成されている換気口14a,換気口14b及び換気口14c,換気口14dを介して外方に排出される。   In the ventilation state, the air that has risen from between the drainage drain 33a and the drainage drain 33b at the center of the roofing material 28 as shown by the arrow passes through the ventilation holes of the ventilation members 21a and 21b. Through from the inside to the outside. The air that has passed is discharged outward through the ventilation holes 14a, 14b, 14c, and 14d formed in the inclined portions 17a and 17b.

一方、雨水は主に換気口14a〜換気口14dの各々を介して傾斜部17a,傾斜部17bの下方に侵入する。侵入した雨水は上述のように換気部材21a,換気部材21bの各々の通気孔を介しては内方側に移動することはできないように構成されている。従って、侵入した雨水は、フランジ部19a,フランジ部19bの各々の下面と平板瓦34a,平板瓦34bの上面との間の隙間から外方に流れ出ることになる。   On the other hand, rainwater mainly enters below the inclined portions 17a and 17b through each of the ventilation ports 14a to 14d. As described above, the infiltrated rainwater cannot move inward through the ventilation holes of the ventilation member 21a and the ventilation member 21b. Accordingly, the infiltrated rainwater flows outward from the gap between the lower surface of each of the flange portions 19a and 19b and the upper surfaces of the flat roof tiles 34a and 34b.

又、換気部材21a,換気部材21bの各々の下面と平板瓦34a,平板瓦34bの上面との間の隙間はほとんど無いためその部分からの雨水の侵入の虞も無い。仮にこの隙間から雨水が侵入した場合にあっても、その量は僅かであり、その雨水は捨水切33a,捨水切33b及び防水紙30a,防水紙30bによって内方への侵入は確実に阻止されることになる。   Further, since there is almost no gap between the lower surface of each of the ventilation members 21a and 21b and the upper surfaces of the flat roof tiles 34a and 34b, there is no danger of rainwater entering therefrom. Even if rainwater enters through this gap, the amount of the rainwater is slight, and the inflow of the rainwater is reliably prevented by the drainage drain 33a, the drainage drain 33b, and the waterproof paper 30a and the waterproof paper 30b. Will be.

図6はこの考案の第2の実施の形態による換気棟の取付け状態を示した概略断面図である。   FIG. 6 is a schematic sectional view showing a state of attachment of a ventilation building according to a second embodiment of the present invention.

図を参照して、換気棟11の基本的な構成は先の第1の実施の形態によるものと同一であるが、換気部材39a,換気部材39bの取付け状態が異なっている。換気部材39a,換気部材39bの各々の寸法は先の第1の実施の形態による換気部材21a,換気部材21bと同一であるが、その取付け状態が反対となっている。即ち、この実施の形態にあっては、台形断面形状の上底に対応する面は傾斜部17a,傾斜部17b側に面しており、その下底に対応する面は平板瓦34a,平板瓦34b側に面している。従って、換気部材39a,換気部材39bの各々に形成されている通気孔の長さは下方に行くに従って長くなることになる。侵入した雨水は下方側に多く存在することになるため、換気部材39a,換気部材39bの防水性能をより効率的に発揮できることになる。通気性能にあっては、先の実施の形態によるものと何ら変わらず同様の効果を奏することになる。   Referring to the figure, the basic configuration of ventilation building 11 is the same as that of the first embodiment, but the mounting state of ventilation members 39a and 39b is different. The dimensions of each of the ventilation members 39a and 39b are the same as those of the ventilation members 21a and 21b according to the first embodiment, but their mounting states are reversed. That is, in this embodiment, the surface corresponding to the upper bottom of the trapezoidal cross-sectional shape faces the inclined portion 17a, the inclined portion 17b side, and the surface corresponding to the lower bottom thereof is the flat tile 34a, the flat tile. 34b side. Therefore, the length of the ventilation holes formed in each of the ventilation member 39a and the ventilation member 39b becomes longer as going downward. Since a large amount of infiltrated rainwater exists on the lower side, the waterproof performance of the ventilation members 39a and 39b can be more efficiently exhibited. Regarding the ventilation performance, the same effect as that of the previous embodiment is obtained.

尚、上記の各実施の形態では、換気部材の寸法、形状を特定しているが、同様の通気機能及び防水機能を発揮するものであれば、他の寸法、形状であっても良い。この場合、特許2610342号の明細書に記載されている風雨試験と同一の条件で同一の効果を奏するものであることが好ましい。   Although the size and shape of the ventilation member are specified in each of the above embodiments, other sizes and shapes may be used as long as they exhibit the same ventilation function and waterproof function. In this case, it is preferable that the same effect can be obtained under the same conditions as those of the wind and rain test described in the specification of Japanese Patent No. 2610342.

又、上記の各実施の形態では、棟板部材に垂直部が含まれているが、この垂直部は必ずしも必要なものではなく、棟板部材の外方端部が屋根材の上面に沿うように棟板部材全体を下方に緩やかに曲げるような形状であっても良い。   Further, in each of the above embodiments, the ridge plate member includes the vertical portion. However, the vertical portion is not always necessary, and the outer end of the ridge plate member may be along the upper surface of the roof material. Alternatively, the shape may be such that the entire ridge plate member is gently bent downward.

更に、上記の各実施の形態では、棟板部材の頂点近辺の下面に断熱材を取り付けてこれに換気部材を取り付けているが、断熱材は必ずしも必要なものではない。又、換気部材はそれ自体断熱機能を含んでいるため断熱材を介さずに直接棟板部材に取り付けても良い。   Further, in each of the above embodiments, the heat insulating material is attached to the lower surface near the vertex of the ridge plate member, and the ventilation member is attached thereto. However, the heat insulating material is not always necessary. Further, since the ventilation member itself has a heat insulating function, the ventilation member may be directly attached to the ridge plate member without using a heat insulating material.

更に、上記の各実施の形態では、棟板部材に形成されている換気口は特定個数で特定形状を有しているが、他の形状や他の個数であっても良い事は言うまでもない。   Furthermore, in each of the above embodiments, the ventilation holes formed in the ridge plate member have a specific number and a specific shape, but it goes without saying that other shapes or other numbers may be used.

更に、上記の各実施の形態では、屋根材の構造を特定しているが、他の構造の屋根材であっても同様の形状であれば同様に適用できる。   Further, in each of the above embodiments, the structure of the roofing material is specified, but the roofing material having another structure can be similarly applied as long as it has the same shape.
