Description

本発明は、建物の棟に設置されて、雨水等の進入を防止しつつ、屋内外の換気を行う通気部材に関し、特に有効開口面積を減らすことなく、防水性能を向上できるものに関する。   The present invention relates to a ventilation member that is installed in a building ridge and ventilates indoors and outdoors while preventing intrusion of rainwater and the like, and particularly relates to a member that can improve waterproof performance without reducing an effective opening area.

建物の棟においては、雨水が家屋内に浸入するのを防止するため、土、なんばん、しっくい等を用いて隅瓦と垂木との隙間を固める湿式工法が従来より用いられていた。しかしながら、湿式工法では、屋内の換気を行うことが困難であるため、近年では、換気機能を有する棟構造が採用されつつある（例えば、特許文献１参照）。このような換気棟では、換気能力が不十分で、かつ、雨水等の侵入に対しての対策も不十分であった。   In the building ridge, a wet method has conventionally been used in which the gap between the corner tile and the rafter is solidified using soil, namba, plaster, etc., in order to prevent rainwater from entering the house. However, since it is difficult to perform indoor ventilation with the wet method, a ridge structure having a ventilation function is being adopted in recent years (see, for example, Patent Document 1). In such a ventilation building, ventilation capacity was insufficient and measures against intrusion of rainwater and the like were insufficient.

一方、通気部材は、予期せぬ積雪にあったり、過度の重量物下に設置されたり、施工時に過度に踏み付けられたりする等によって大きな負荷がかかる場合には、開口部が圧潰されて通気性能が劣化するおそれがある。   On the other hand, if the ventilation member is subject to unexpected snow accumulation, placed under an excessively heavy object, or excessively stepped on during construction, the opening is crushed and the ventilation performance is reduced. May deteriorate.

このため、内部に十分な通気スペースを有すると共に、雨雪や虫等の進入を阻止し、しかも縦方向の強度に優れた部材が開発されている（例えば特許文献２，３参照）。
特開平５−１７１７５９号公報 特許２６７７３１９号公報 特開２００６−１０４７６７号公報 For this reason, a member has been developed that has a sufficient ventilation space inside and prevents entry of rain, snow, insects, and the like and is excellent in longitudinal strength (for example, see Patent Documents 2 and 3).
JP-A-5-171759 Japanese Patent No. 2677319 JP 2006-104767 A

上述した通気部材では、次のような問題があった。すなわち、柱体の配設密度を低めたり、柱体を細くすると、通風性能は向上するものの、強度が低下するとともに、風速が高くなる（例えば風速３５ｍ／ｓ）と漏水が発生しやすくなる。一方、柱体を太くしたり、配設密度を高めると開口面積が減少し、十分な通風性能を発揮できない。また、通気部材の長さは施行面や他の部材とのバランスからこれ以上長くすることができない。   The ventilation member described above has the following problems. That is, if the arrangement density of the column bodies is lowered or the column bodies are thinned, the ventilation performance is improved, but the strength is lowered and the wind speed is increased (for example, the wind speed is 35 m / s), and water leakage is likely to occur. On the other hand, if the pillars are thickened or the arrangement density is increased, the opening area is reduced, and sufficient ventilation performance cannot be exhibited. Further, the length of the ventilation member cannot be increased any longer due to the balance with the enforcement surface and other members.

そこで本発明は、通気性能及び強度を維持しつつ、防水性能を向上できる通気部材を提供することを目的としている。   Therefore, an object of the present invention is to provide a ventilation member that can improve waterproof performance while maintaining ventilation performance and strength.

前記課題を解決し目的を達成するために、本発明の通気部材は次のように構成されている。   In order to solve the above problems and achieve the object, the ventilation member of the present invention is configured as follows.

屋内と屋外との間で空気の流通を図る通気部材において、互いに平行して配置された天板及び底板と、これら天板と底板との間に設けられ、互いに間隙を有して配置された複数の柱体と、上記間隙であって上記天板及び上記底板と平行に、かつ、空気の流通方向と交差する方向に上記複数の柱体間に挿入された棒材からなる抵抗部材とを備え、上記柱体は、それぞれ上記天板側と上記底板側を大径側とする一対の円錐台を組み合せて形成されていることを特徴とする。 In a ventilation member that distributes air between indoors and outdoors, a top plate and a bottom plate that are arranged in parallel to each other, and provided between the top plate and the bottom plate, are arranged with a gap therebetween. a plurality of pillar bodies, parallel to the top plate and the bottom plate are the above gap, and resistance members consisting inserted has been rod between said plurality of pillar bodies in a direction crossing the flow direction of the air The columnar body is formed by combining a pair of truncated cones having a large diameter side on the top plate side and the bottom plate side, respectively.

屋内と屋外との間で空気の流通を図る通気部材において、互いに平行して配置された天板及び底板と、これら天板と底板との間に設けられ、空気の流通方向に沿って形成された複数の壁部と、上記天板又は上記底板に設けられ、上記空気の流通方向に交差する方向に形成されたスリットと、このスリットに着脱自在に取り付けられ、上記空気の流通方向に交差する方向に延びる抵抗板材とを備えていることを特徴とする。   In a ventilation member that distributes air between indoors and outdoors, the top plate and the bottom plate that are arranged in parallel to each other, provided between the top plate and the bottom plate, are formed along the air flow direction. A plurality of walls, a slit provided in the top plate or the bottom plate and formed in a direction crossing the air flow direction, and detachably attached to the slit, and crossing the air flow direction. And a resistance plate material extending in the direction.

本発明によれば、通気性能及び強度を維持しつつ、防水性能を向上することが可能となる。   ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to improve waterproof performance, maintaining ventilation performance and intensity | strength.

図１は本発明の第１実施の形態に係る通気部材３０が組み込まれた換気棟構造を示す縦断面図、図２は通気部材３０の要部を模式的に示す斜視図、図３は通気部材３０の開口面積を示す説明図である。また、図４は比較例に係る通気部材３０の要部を模式的に示す斜視図、図５は通気部材３０の開口面積を示す説明図である。なお、図中Ｗは通風方向を示している。   FIG. 1 is a longitudinal sectional view showing a ventilation wing structure in which a ventilation member 30 according to a first embodiment of the present invention is incorporated, FIG. 2 is a perspective view schematically showing a main part of the ventilation member 30, and FIG. 4 is an explanatory view showing an opening area of a member 30. FIG. 4 is a perspective view schematically showing a main part of the ventilation member 30 according to the comparative example, and FIG. 5 is an explanatory view showing an opening area of the ventilation member 30. As shown in FIG. In addition, W has shown the ventilation direction in the figure.

図１に示すように、換気棟構造は、相対向し、隙間Ｐを設けて配置された一対の垂木１０,１０と、これら垂木１０,１０の上面に設けられた野地板１１とを備えている。上記隙間Ｐ上方には、金属材製のカバー部材２０が設けられ、カバー部材２０と野地板１１との間には通気部材３０が例えば三層にして設けられている。   As shown in FIG. 1, the ventilation building structure includes a pair of rafters 10 and 10 arranged opposite to each other with a gap P therebetween, and a field board 11 provided on the upper surface of these rafters 10 and 10. Yes. A metal cover member 20 is provided above the gap P, and a ventilation member 30 is provided between the cover member 20 and the base plate 11 in, for example, three layers.

一層の通気部材３０は、互いに平行に配置された天板３１と底板３２とを備えており、いずれも野地板１１とほぼ平行に配置されている。天板３１と底板３２との間は通風路が形成されている。   The one-layer ventilation member 30 includes a top plate 31 and a bottom plate 32 arranged in parallel with each other, and both are arranged almost in parallel with the field plate 11. A ventilation path is formed between the top plate 31 and the bottom plate 32.

天板３１と底板３２との間には間隔をおいて配置された円柱（柱体）３３が設けられている。円柱３３の配置は例えば図２に示すように縦横に配置されている。また、円柱３３の間には通風方向Ｗに交差する向きに丸棒（抵抗体）３４が配置されている。   A column (column body) 33 is provided between the top plate 31 and the bottom plate 32 with a space therebetween. The cylinders 33 are arranged vertically and horizontally, for example, as shown in FIG. Further, round bars (resistors) 34 are arranged between the cylinders 33 in a direction intersecting with the ventilation direction W.

なお、通気部材３０の材質は特に限定されるものではないが、アルミ、ステンレス、セラミックス及び合成樹脂等を例示でき、低コスト性の観点からは合成樹脂が好ましい。   In addition, although the material of the ventilation member 30 is not specifically limited, aluminum, stainless steel, ceramics, a synthetic resin, etc. can be illustrated and a synthetic resin is preferable from a viewpoint of low cost.

このように構成された通気部材３０が組み込まれた換気棟であると、屋内から上昇した湿気を含んだ空気はカバー部材２０の空間２１に集まる。一方、図１中左側の通気部材３０を介して外部からの空気が空間２１へ流入し、右側の通気部材３０を介して建物外部に流出する。このように、自然の風が建物内部に流入することで、換気を容易に行うことができ、屋内の乾燥を図ることが可能である。   In the ventilation building in which the ventilation member 30 configured as described above is incorporated, the air containing moisture rising from the indoors gathers in the space 21 of the cover member 20. On the other hand, air from the outside flows into the space 21 through the left ventilation member 30 in FIG. 1 and flows out of the building through the right ventilation member 30. In this way, natural wind flows into the building, so that ventilation can be easily performed and indoor drying can be achieved.

一方、台風等のように強い風と雨が吹きつけた場合には、通気部材３０から内部に雨水が浸入する。しかしながら、丸棒３４があるため浸入が一定以上進まず、屋内への雨水の浸入を防止できる。   On the other hand, when strong wind and rain are blown, such as a typhoon, rainwater enters from the ventilation member 30 into the inside. However, since there is a round bar 34, the infiltration does not progress beyond a certain level, and rain water can be prevented from entering indoors.

ここで、丸棒３４がある場合と、丸棒３４がない場合とで有効開口面積を比較する。ここで、通気部材３０の有効開口面積は、部材の断面部分の実開口部分が対象となる。   Here, the effective opening area is compared between the case where there is a round bar 34 and the case where there is no round bar 34. Here, the effective opening area of the ventilation member 30 is the actual opening portion of the cross-sectional portion of the member.

図３及び図５に示すように、横９６．１５ｍｍ×高さ８ｍｍｍの部分、直径６ｍｍの円柱３３を間隔６ｍｍで配置し、直径４ｍｍの丸棒３４の配置の有無で比較する。図４に示すように、開口部は斜線で示す領域となり、有効開口面積Ｋ１は３８４．６ｍｍ２となる。これに対し、図４に示すように丸棒３４が無い場合には、図５に示すように、横９６．１５ｍｍ×高さ８ｍｍｍの部分、直径６ｍｍの円柱３３を間隔６ｍｍで配置した場合、開口部は斜線で示す領域となり、有効開口面積Ｋ２は３８５．２ｍｍ２となる。したがって、丸棒３４の配置の有無で有効開口面積はほとんど変わらない。 As shown in FIG. 3 and FIG. 5, a portion having a width of 96.15 mm × a height of 8 mm, and a cylinder 33 having a diameter of 6 mm are arranged at an interval of 6 mm, and a comparison is made with or without a round bar 34 having a diameter of 4 mm. As shown in FIG. 4, the opening is a region indicated by oblique lines, and the effective opening area K1 is 384.6 mm 2 . On the other hand, when there is no round bar 34 as shown in FIG. 4, as shown in FIG. 5, when a horizontal 96.15 mm × height 8 mm portion and a cylinder 33 with a diameter of 6 mm are arranged at an interval of 6 mm, The opening is a region indicated by oblique lines, and the effective opening area K2 is 385.2 mm 2 . Therefore, the effective opening area hardly changes depending on whether or not the round bar 34 is arranged.

なお、天板３１と底板３２とは多数の円柱３３で支持されているので、上下方向の荷重に対して高い強度を維持することができる。したがって、積雪や過度の荷重に耐えることができ、開口部が圧潰されて通気性能が劣化する虞はない。   In addition, since the top plate 31 and the bottom plate 32 are supported by a large number of cylinders 33, high strength can be maintained with respect to loads in the vertical direction. Therefore, it can withstand snow load and excessive load, and there is no possibility that the opening is crushed and the ventilation performance is deteriorated.

上述したように、本発明の第１の実施の形態に係る通気部材３０が組み込まれた換気棟においては、通気性能及び強度を維持しつつ、防水性能を向上することが可能となる。   As described above, in the ventilation building incorporating the ventilation member 30 according to the first embodiment of the present invention, it is possible to improve the waterproof performance while maintaining the ventilation performance and strength.

なお、円柱３３の代わりに多角形柱を用いても良い。また、丸棒３４の代わりに板材を用いてもよい。   A polygonal column may be used instead of the column 33. Further, a plate material may be used instead of the round bar 34.

図６は本発明の第２の実施の形態に係る通気部材４０の平面図、図７は通気部材４０を図６のＸ１−Ｘ１線の位置における開口面積を示す説明図、図８は通気部材４０を図６のＸ２−Ｘ２線の位置における開口面積を示す説明図、図９は通気部材４０を図６のＹ−Ｙ線の位置で切断して矢印方向に見た断面図である。   FIG. 6 is a plan view of the ventilation member 40 according to the second embodiment of the present invention, FIG. 7 is an explanatory view showing the opening area of the ventilation member 40 at the position of line X1-X1 in FIG. 6, and FIG. 40 is an explanatory view showing the opening area at the position of line X2-X2 in FIG. 6, and FIG. 9 is a cross-sectional view of the ventilation member 40 cut at the position of line Y-Y in FIG.

通気部材４０は、通気部材３０と同様の位置に取り付けられるものであって、互いに平行に配置された天板４１と底板４２とを備えており、いずれも野地板１１とほぼ平行に配置されている。天板４１と底板４２との間は通風路が形成されている。   The ventilation member 40 is attached at the same position as the ventilation member 30, and includes a top plate 41 and a bottom plate 42 arranged in parallel to each other, both of which are arranged almost in parallel with the base plate 11. Yes. A ventilation path is formed between the top plate 41 and the bottom plate 42.

天板４１と底板４２との間には間隔をおいて配置された柱体４３が設けられている。柱体４３は、それぞれ天板４１側と底板４２側を大径側とする一対の円錐台を組み合せて形成されており、中央部が最も径が小さくなってくびれた構造をしている。また、柱体４３の間には通風方向Ｗに交差する向きに丸棒（抵抗体）４４が配置されている。   A column 43 is provided between the top plate 41 and the bottom plate 42 so as to be spaced from each other. The column body 43 is formed by combining a pair of truncated cones each having a large diameter side on the top plate 41 side and the bottom plate 42 side, and has a constricted structure with the center portion having the smallest diameter. Further, round bars (resistors) 44 are arranged between the column bodies 43 in a direction intersecting with the ventilation direction W.

このように構成された通気部材４０が組み込まれた換気棟であると、屋内から上昇した湿気を含んだ空気がカバー部材２０の空間２１に集まる。そして、通気部材４０を介して屋外へと排出される。   In the ventilation building in which the ventilation member 40 configured as described above is incorporated, air containing moisture rising from the indoors gathers in the space 21 of the cover member 20. Then, it is discharged to the outside through the ventilation member 40.

一方、台風等のように強い風と雨が吹きつけた場合には、通気部材４０から内部に雨水が浸入する。しかしながら、丸棒４４があるため浸入を防止できる。   On the other hand, when strong wind and rain are blown, such as typhoon, rainwater enters from the ventilation member 40 into the inside. However, since there is a round bar 44, intrusion can be prevented.

ここで、丸棒４４がある場合と、丸棒４４がない場合とで有効開口面積を比較する。ここで、通気部材４０の有効開口面積は、最も外部に面した部位における領域が対象となる。   Here, the effective opening area is compared between the case with the round bar 44 and the case without the round bar 44. Here, the effective opening area of the ventilation member 40 is a region in a portion facing the outermost portion.

図７及び図８に示すように、通風方向Ｗに交差する向きに沿ってＸ１−Ｘ１線部分とＸ２−Ｘ２線部分とで有効開口面積の比較を行う。Ｘ１−Ｘ１線部分においては図７に示すように、開口部は斜線で示す領域となり、有効開口面積Ｓ１は４３６．３ｍｍ２となる。これに対し、図８に示すように丸棒４４が挿入されたＸ２−Ｘ２線部分においては、開口部は斜線で示す領域となり、有効開口面積Ｓ２は４３８．０ｍｍ２となる。したがって、丸棒４４の配置の有無で有効開口面積はほとんど変わらない。 As shown in FIGS. 7 and 8, the effective opening areas are compared between the X1-X1 line portion and the X2-X2 line portion along the direction intersecting the ventilation direction W. In the X1-X1 line portion, as shown in FIG. 7, the opening is a hatched region, and the effective opening area S1 is 436.3 mm 2 . On the other hand, as shown in FIG. 8, in the X2-X2 line portion in which the round bar 44 is inserted, the opening is a hatched region, and the effective opening area S2 is 438.0 mm 2 . Therefore, the effective opening area hardly changes depending on whether or not the round bar 44 is arranged.

なお、図９は丸棒４４の挿入位置を示している。図９に示すように、柱体４３は中央部がくびれているので、直径１ｍｍの丸棒４４を挿入することができる。   FIG. 9 shows the insertion position of the round bar 44. As shown in FIG. 9, since the central part of the column 43 is constricted, a round bar 44 having a diameter of 1 mm can be inserted.

一方、天板４１と底板４２とは多数の柱体４３で支持されているので、上下方向の荷重に対して高い強度を維持することができる。したがって、積雪や過度の荷重に耐えることができ、開口部が圧潰されて通気性能が劣化する虞はない。   On the other hand, since the top plate 41 and the bottom plate 42 are supported by a large number of column bodies 43, high strength can be maintained against the load in the vertical direction. Therefore, it can withstand snow load and excessive load, and there is no possibility that the opening is crushed and the ventilation performance is deteriorated.

上述したように、本発明の第２の実施の形態に係る通気部材４０が組み込まれた換気棟においては、通気性能及び強度を維持しつつ、防水性能を向上することが可能となる。   As described above, in the ventilation building incorporating the ventilation member 40 according to the second embodiment of the present invention, it is possible to improve the waterproof performance while maintaining the ventilation performance and strength.

図１０は、本発明の第３の実施の形態に係る通気部材５０を示す平面図及び正面図、図１１は、通気部材５０に組み込まれる抵抗板材６０を示す正面図である。   FIG. 10 is a plan view and a front view showing the ventilation member 50 according to the third embodiment of the present invention, and FIG. 11 is a front view showing the resistance plate member 60 incorporated in the ventilation member 50.

通気部材５０は、通気部材３０と同様の位置に取り付けられるものであって、互いに平行に配置された天板５１と底板５２とを備えており、いずれも野地板１１とほぼ平行に配置されている。天板５１と底板５２との間は通風路が形成されている。   The ventilation member 50 is attached at the same position as the ventilation member 30, and includes a top plate 51 and a bottom plate 52 arranged in parallel to each other, both of which are arranged substantially in parallel with the base plate 11. Yes. A ventilation path is formed between the top plate 51 and the bottom plate 52.

天板５１と底板５２との間には間隔をおき、かつ、通風方向Ｗに沿って複数の壁部５３が一定のピッチＰ（例えば１１．２５ｍｍ）で平行に配置され、間隙の幅Ｌは例えば１０ｍｍに設定されている。天板５１には、通風方向Ｗに直交する向きに延びるスリット５４が３組設けられている。これらスリット５４には、抵抗板材６０が着脱自在に挿入することができる。   A space is provided between the top plate 51 and the bottom plate 52, and a plurality of wall portions 53 are arranged in parallel at a constant pitch P (for example, 11.25 mm) along the ventilation direction W. The width L of the gap is as follows. For example, it is set to 10 mm. The top plate 51 is provided with three sets of slits 54 extending in a direction orthogonal to the ventilation direction W. The resistance plate 60 can be detachably inserted into the slits 54.

抵抗板材６０は、厚さ０．５ｍｍでスリット５４の幅より僅かに広いベース部６１と、このベース部６１に取り付けられた４枚の板材６２とを備えている。板材６２は壁部５３相互の間隔よりは狭い幅Ｍ１（例えば５．６２５ｍｍ）で設けられている。ここで、抵抗板材６０がある場合の開口率を算出すると、開口率は５１．８％となる。   The resistance plate member 60 includes a base portion 61 having a thickness of 0.5 mm and slightly wider than the width of the slit 54, and four plate members 62 attached to the base portion 61. The plate member 62 is provided with a width M1 (for example, 5.625 mm) narrower than the interval between the wall portions 53. Here, when the aperture ratio when the resistance plate material 60 is present is calculated, the aperture ratio is 51.8%.

また、スリット５４は複数設けられているので、図１０の右側に示すように、抵抗板材６０をずらすことで開口率を同一のまま、通風抵抗を増やすことができる。   Since a plurality of slits 54 are provided, the ventilation resistance can be increased while keeping the aperture ratio the same by shifting the resistance plate member 60 as shown on the right side of FIG.

なお、天板５１と底板５２とは多数の壁部５３で支持されているので、上下方向の荷重に対して高い強度を維持することができる。したがって、積雪や過度の荷重に耐えることができ、開口部が圧潰されて通気性能が劣化する虞はない。   In addition, since the top plate 51 and the bottom plate 52 are supported by many wall parts 53, high intensity | strength can be maintained with respect to the load of an up-down direction. Therefore, it can withstand snow load and excessive load, and there is no possibility that the opening is crushed and the ventilation performance is deteriorated.

上述したように、本発明の第３の実施の形態に係る通気部材５０が組み込まれた換気棟においては、通気性能及び強度を維持しつつ、防水性能を向上することが可能となる。   As described above, in the ventilation building incorporating the ventilation member 50 according to the third embodiment of the present invention, the waterproof performance can be improved while maintaining the ventilation performance and strength.

図１２は、上記抵抗板材６０の変形例に係る抵抗板材７０を示す正面図である。抵抗板材７０は、厚さ０．５ｍｍでスリット５４の幅より僅かに広いベース部７１と、このベース部７１に取り付けられた４枚の板材７２とを備えている。板材７２は壁部５３相互の間隔よりは狭い幅Ｍ２（例えば３．７５ｍｍ）で設けられている。   FIG. 12 is a front view showing a resistance plate material 70 according to a modification of the resistance plate material 60. The resistance plate member 70 includes a base portion 71 having a thickness of 0.5 mm and slightly wider than the width of the slit 54, and four plate members 72 attached to the base portion 71. The plate member 72 is provided with a width M2 (eg, 3.75 mm) narrower than the interval between the wall portions 53.

本変形例における開口率は６５．５％となる。 The aperture ratio in this modification is 65.5%.

図１３は、本発明の第４の実施の形態に係る通気部材８０を示す正面図である。通気部材８０は、通気部材３０と同様の位置に取り付けられるものであって、互いに平行に配置された天板８１と底板８２とを備えており、いずれも野地板１１とほぼ平行に配置されている。天板８１と底板８２との間は通風路が形成されている。   FIG. 13 is a front view showing a ventilation member 80 according to the fourth embodiment of the present invention. The ventilation member 80 is attached at the same position as the ventilation member 30, and includes a top plate 81 and a bottom plate 82 that are arranged in parallel to each other, both of which are arranged almost in parallel with the base plate 11. Yes. A ventilation path is formed between the top plate 81 and the bottom plate 82.

天板８１と底板８２との間には間隔をおき、かつ、通風方向Ｗに沿って複数の壁部８３が一定のピッチで平行に配置され、間隙８４が形成されている。   A space is formed between the top plate 81 and the bottom plate 82, and a plurality of wall portions 83 are arranged in parallel at a constant pitch along the ventilation direction W to form a gap 84.

間隙８４には、網材９０〜９３が設けられている。網材９０の網目の間隔を調整することで開口率を任意に調整することができる。   In the gap 84, mesh members 90 to 93 are provided. The aperture ratio can be arbitrarily adjusted by adjusting the mesh interval of the mesh material 90.

なお、天板８１と底板８２とは多数の壁部８３で支持されているので、上下方向の荷重に対して高い強度を維持することができる。したがって、積雪や過度の荷重に耐えることができ、開口部が圧潰されて通気性能が劣化する虞はない。   In addition, since the top plate 81 and the bottom plate 82 are supported by a large number of wall portions 83, it is possible to maintain high strength against the load in the vertical direction. Therefore, it can withstand snow load and excessive load, and there is no possibility that the opening is crushed and the ventilation performance is deteriorated.
