Description
本発明は、建造物の外壁材の上方に設置される外壁材上端換気装置に関する。 The present invention relates to an exterior wall material top end ventilation device that is installed above the exterior wall material of a building.
特許文献１では、外壁材と軒天材との境界部分で用いる見切縁を提案している。
特許文献１の見切縁は、上板と、上板の両縁から垂下される外板と内板とからなり、外板と内板の端縁には折り返しが設けられ、内板の中間にはリブが形成され、更に上板の上端部外側角部は凹角部となっており、見切縁の内側には板材の嵌合溝が形成されている。
Patent Document 1 proposes a trim to be used at the boundary between an exterior wall material and an eaves soffit material.
The trim in Patent Document 1 consists of an upper plate and an outer plate and an inner plate hanging down from both edges of the upper plate, with a fold at the end edges of the outer plate and the inner plate and a rib formed in the middle of the inner plate, and furthermore the outer corner of the upper end part of the upper plate is a recessed corner, and a fitting groove for the plate material is formed on the inside of the trim.
しかし、特許文献１に示される見切縁では、外壁材に強く吹き付け、軒天材と見切縁との間または外壁材と見切縁との間から壁通気層内へ浸入しようとする雨水に対する抵抗が少なく、防水性能に問題がある。また、軒天材表面や外壁材表面に、デザインとしての凹凸がある場合や、嵌合溝への外壁材の飲み込み代が短い場合には、壁通気層内への雨水の浸入リスクがさらに高まる。
なお、外壁材と換気部材との間などでの部材間での防水処理には、シーリング材が用いられることが多いが、シーリング材は固化に時間を要することから施工手間になりがちである。
However, the trim shown in Patent Document 1 has little resistance to rainwater that is sprayed strongly onto the exterior wall material and tries to infiltrate into the wall ventilation layer from between the eaves soffit material and the trim, or between the exterior wall material and the trim, and has problems with waterproofing. In addition, if the surface of the eaves soffit material or the exterior wall material has irregularities as a design, or if the exterior wall material does not fit into the fitting groove well, the risk of rainwater infiltrating into the wall ventilation layer increases.
Furthermore, sealants are often used for waterproofing between components, such as between exterior wall materials and ventilation components. However, sealants take time to harden, which can make their application time-consuming.
本発明は、外壁材の上端と換気部材との間での防水性能を確保でき、外壁材に沿って上昇する雨水に対する防水性能に優れる外壁材上端換気装置を提供することを目的とする。 The present invention aims to provide an exterior wall material upper end ventilation device that can ensure waterproofing between the upper end of the exterior wall material and the ventilation member, and has excellent waterproofing against rainwater that rises along the exterior wall material.

本発明の外壁材上端換気装置によれば、第１防水パッキンにより見切縁上面板と換気部材底面板との間の防水を行い、第２防水パッキンにより見切縁後面板の前面と外壁材との間の防水を行うため、外壁材の上端と換気部材との間での防水性能を確保でき、外壁材に沿って上昇する雨水は、水切空間に導かれ、見切縁前面板に沿って落下するために、換気部材前面板には導かれず、換気孔から換気通路に流入しないので防水性能に優れる。 According to the exterior wall material upper end ventilation device of the present invention, the first waterproof packing provides waterproofing between the upper panel of the trim edge and the bottom panel of the ventilation member, and the second waterproof packing provides waterproofing between the front surface of the rear panel of the trim edge and the exterior wall material, ensuring waterproofing between the upper end of the exterior wall material and the ventilation member. Rainwater that rises along the exterior wall material is led to the water drainage space and falls along the front panel of the trim edge, so it is not led to the front panel of the ventilation member and does not flow into the ventilation passage from the ventilation hole, resulting in excellent waterproofing.
本発明の第１の実施の形態による外壁材上端換気装置は、外壁材の上端を覆う見切縁と、見切縁の上方に配置される換気部材とを備え、見切縁は、外壁材の上端を覆う見切縁上面板と、見切縁上面板の前端から垂下させた見切縁前面板と、見切縁上面板の後端から垂下させた見切縁後面板とからなり、換気部材は、見切縁上面板の上面に対向して配置される換気部材底面板と、換気部材底面板の前端から立ち上げた換気部材前面板と、換気部材前面板の上端から後方に延出させた換気部材天面板とからなり、換気部材前面板には、換気孔が形成され、換気部材底面板と換気部材天面板との間で、換気部材前面板の後方に換気通路が形成され、見切縁上面板と換気部材底面板との間に配置される第１防水パッキンと、見切縁後面板の前面と外壁材との間に配置される第２防水パッキンとを備え、見切縁上面板の奥行寸法を外壁材の厚さよりも大きくして、見切縁前面板と外壁材との間に水切空間を形成するものである。本実施の形態によれば、第１防水パッキンにより見切縁上面板と換気部材底面板との間の防水を行い、第２防水パッキンにより見切縁後面板の前面と外壁材との間の防水を行うため、外壁材の上端と換気部材との間での防水性能を確保でき、外壁材に沿って上昇する雨水は、水切空間に導かれ、見切縁前面板に沿って落下するために、換気部材前面板には導かれず、換気孔から換気通路に流入しないので防水性能に優れる。 The exterior wall material upper end ventilation device according to the first embodiment of the present invention comprises a trim covering the upper end of the exterior wall material and a ventilation member arranged above the trim, the trim comprising an upper trim panel covering the upper end of the exterior wall material, a trim front panel hanging down from the front end of the upper trim panel, and a trim rear panel hanging down from the rear end of the upper trim panel, the ventilation member comprising a ventilation member bottom panel arranged opposite the upper surface of the upper trim panel, a ventilation member front panel raised from the front end of the ventilation member bottom panel, and a ventilation member front panel raised from the upper end of the ventilation member front panel. The ventilation member comprises a top panel of the ventilation member extending rearward from the top panel of the ventilation member, a ventilation hole is formed in the front panel of the ventilation member, a ventilation passage is formed between the bottom panel of the ventilation member and the top panel of the ventilation member, a first waterproof packing is arranged between the top panel of the trim edge and the bottom panel of the ventilation member, and a second waterproof packing is arranged between the front panel of the trim edge rear panel and the exterior wall material, and the depth dimension of the top panel of the trim edge is made larger than the thickness of the exterior wall material to form a water drainage space between the front panel of the trim edge and the exterior wall material. According to this embodiment, the first waterproof packing provides waterproofing between the top panel of the trim edge and the bottom panel of the ventilation member, and the second waterproof packing provides waterproofing between the front panel of the trim edge rear panel and the exterior wall material, so that waterproofing performance can be ensured between the upper end of the exterior wall material and the ventilation member, and rainwater rising along the exterior wall material is led to the water drainage space and falls along the front panel of the trim edge, so it is not led to the front panel of the ventilation member and does not flow into the ventilation passage from the ventilation hole, resulting in excellent waterproofing performance.
本発明の第２の実施の形態は、第１の実施の形態による外壁材上端換気装置において、見切縁前面板と垂下部材との間には、見切縁側通気路が形成され、換気部材前面板と垂下部材との間には、換気部材側通気路が形成されるものである。本実施の形態によれば、雨水は、見切縁側通気路及び換気部材側通気路を上昇しなければ換気孔に至らないため、換気通路に流入しにくく、更に防水性に優れる。 In the second embodiment of the present invention, in the exterior wall material upper end ventilation device according to the first embodiment, a trim side air passage is formed between the trim front panel and the hanging member, and a ventilation member side air passage is formed between the ventilation member front panel and the hanging member. According to this embodiment, rainwater does not reach the ventilation hole unless it rises up the trim side air passage and the ventilation member side air passage, so it is less likely to flow into the ventilation passage and is also more waterproof.
本発明の第３の実施の形態は、第２の実施の形態による外壁材上端換気装置において、換気部材側通気路と見切縁側通気路との通気路奥行寸法を異ならせたものである。本実施の形態によれば、換気部材側通気路と見切縁側通気路との通気路奥行寸法を異ならせることで、雨水の流速が変化するため乱流が発生し、雨水は換気通路に流入しにくい。 The third embodiment of the present invention is an exterior wall material upper end ventilation device according to the second embodiment, in which the ventilation member side air passage and the trim side air passage have different air passage depth dimensions. According to this embodiment, by making the ventilation member side air passage and the trim side air passage have different air passage depth dimensions, the flow speed of rainwater changes, causing turbulence, and rainwater is less likely to flow into the ventilation passage.
本発明の第４の実施の形態は、第１から第３のいずれかの実施の形態による外壁材上端換気装置において、換気部材は、換気通路を形成する換気部材後面板を有し、換気部材前面板は外壁材より前方に位置し、換気部材後面板は外壁材より後方に位置するものである。本実施の形態によれば、換気通路の奥行寸法を大きくできることで、換気通路に流入した雨水を換気通路に留めることができ、屋内に雨水が侵入することはない。 In the fourth embodiment of the present invention, in the exterior wall material upper end ventilation device according to any one of the first to third embodiments, the ventilation member has a ventilation member rear panel that forms a ventilation passage, the ventilation member front panel is located forward of the exterior wall material, and the ventilation member rear panel is located rearward of the exterior wall material. According to this embodiment, the depth dimension of the ventilation passage can be increased, so that rainwater that flows into the ventilation passage can be kept in the ventilation passage, and rainwater will not enter the room.
本発明の第５の実施の形態は、第４の実施の形態による外壁材上端換気装置において、換気通路には内部防水壁を設け、内部防水壁を、換気部材天面板の後端から垂下させ、換気部材後面板を、換気部材底面板の後端から立ち上げ、換気孔から換気通路に流入する空気は、換気部材前面板と内部防水壁との間では下方に向けた流れとなり、内部防水壁と換気部材後面板との間では上方に向けた流れとなるものである。本実施の形態によれば、雨水は、内部防水壁によって下方に向けた流れの後に上方に向けた流れとなるために、屋内に侵入することはない。 In the fifth embodiment of the present invention, in the exterior wall material upper end ventilation device according to the fourth embodiment, an internal waterproof wall is provided in the ventilation passage, the internal waterproof wall is hung down from the rear end of the ventilation member top panel, and the ventilation member rear panel is raised up from the rear end of the ventilation member bottom panel, so that the air flowing into the ventilation passage from the ventilation hole flows downward between the ventilation member front panel and the internal waterproof wall, and flows upward between the internal waterproof wall and the ventilation member rear panel. According to this embodiment, rainwater flows downward through the internal waterproof wall and then flows upward, so it does not enter the room.
本発明の第６の実施の形態は、第５の実施の形態による外壁材上端換気装置において、換気部材底面板の前端を、見切縁上面板の前端より前方に突出させたものである。本実施の形態によれば、見切縁側通気路を上昇する雨水を換気部材底面板に衝突させることができ、雨水は換気通路に流入しにくい。 The sixth embodiment of the present invention is an exterior wall material upper end ventilation device according to the fifth embodiment, in which the front end of the ventilation member bottom plate protrudes forward from the front end of the trim top plate. According to this embodiment, rainwater rising up the trim side ventilation passage can be made to collide with the ventilation member bottom plate, and the rainwater is less likely to flow into the ventilation passage.
本発明の第７の実施の形態は、第４の実施の形態による外壁材上端換気装置において、換気通路には、換気部材底面板の後端から立ち上げた内部防水壁を設け、内部防水壁の上端を内部防水壁の下端よりも換気部材前面板に近接させたものである。本実施の形態によれば、換気孔から流入する雨水を換気部材後面板に至ることを防止できる。 The seventh embodiment of the present invention is an exterior wall material upper end ventilation device according to the fourth embodiment, in which an internal waterproof wall is provided in the ventilation passageway, rising from the rear end of the bottom panel of the ventilation member, and the upper end of the internal waterproof wall is closer to the front panel of the ventilation member than the lower end of the internal waterproof wall. This embodiment makes it possible to prevent rainwater flowing in from the ventilation hole from reaching the rear panel of the ventilation member.

本実施例による外壁材上端換気装置は、見切縁上面板１１の奥行寸法Ｌ１を外壁材９９の厚さＬ２よりも大きくすることで、見切縁前面板１２と外壁材９９との間に水切空間Ｂを形成している。
また、本実施例による外壁材上端換気装置は、換気部材底面板２１の前端は、見切縁上面板１１の前端より前方に突出させている。そして、見切縁前面板１２と鼻隠し９７との間には、見切縁側通気路Ｃが形成され、換気部材前面板２２と鼻隠し９７との間には、換気部材側通気路Ｄが形成される。
従って、見切縁側通気路Ｃは、換気部材側通気路Ｄよりも、通気路奥行寸法が大きく、換気部材側通気路Ｄと見切縁側通気路Ｃとの通気路奥行寸法を異ならせている。
FIG. 2 is an enlarged cross-sectional view of a main portion of FIG.
In this embodiment, the exterior wall material upper end ventilation device forms a drainage space B between the edge front panel 12 and the exterior wall material 99 by making the depth dimension L1 of the edge upper panel 11 larger than the thickness L2 of the exterior wall material 99.
In addition, in the exterior wall material upper end ventilation device according to this embodiment, the front end of the ventilation member bottom plate 21 protrudes forward from the front end of the trim top plate 11. Then, between the trim front plate 12 and the fascia board 97, a trim side ventilation passage C is formed, and between the ventilation member front plate 22 and the fascia board 97, a ventilation member side ventilation passage D is formed.
Therefore, the edge side air passage C has a larger air passage depth dimension than the ventilation member side air passage D, and the ventilation member side air passage D and the edge side air passage C have different air passage depth dimensions.
本実施例によれば、第１防水パッキン３１により見切縁上面板１１と換気部材底面板２１との間の防水を行い、第２防水パッキン３２により見切縁後面板１３の前面と外壁材９９との間の防水を行うため、外壁材９９の上端と換気部材２０との間での防水性能を確保でき、外壁材９９に沿って上昇する雨水は、水切空間Ｂに導かれ、見切縁前面板１２に沿って落下するために、換気部材前面板２２には導かれず、換気孔２７から換気通路Ａに流入しないので防水性能に優れる。 According to this embodiment, the first waterproof packing 31 provides waterproofing between the trim top panel 11 and the ventilation member bottom panel 21, and the second waterproof packing 32 provides waterproofing between the front surface of the trim rear panel 13 and the exterior wall material 99, ensuring waterproofing between the upper end of the exterior wall material 99 and the ventilation member 20. Rainwater rising along the exterior wall material 99 is guided to the drainage space B and falls along the trim front panel 12, so it is not guided to the ventilation member front panel 22 and does not flow into the ventilation passage A from the ventilation hole 27, resulting in excellent waterproofing.
また、本実施例によれば、雨水は、見切縁側通気路Ｃ及び換気部材側通気路Ｄを上昇しなければ換気孔２７に至らないため、換気通路Ａに流入しにくく、更に防水性に優れる。
また、本実施例によれば、換気部材側通気路Ｄと見切縁側通気路Ｃとの通気路奥行寸法を異ならせることで、雨水の流速が変化するため乱流が発生し、雨水は換気通路Ａに流入しにくい。
また、本実施例によれば、見切縁側通気路Ｃを上昇する雨水を換気部材底面板２１に衝突させることができ、雨水は換気通路Ａに流入しにくい。
Furthermore, according to this embodiment, rainwater cannot reach the ventilation hole 27 unless it rises through the trim side ventilation passage C and the ventilation member side ventilation passage D, so that the rainwater is less likely to flow into the ventilation passage A, and the waterproofing is also excellent.
In addition, according to this embodiment, by making the ventilation passage depth dimensions of the ventilation member side ventilation passage D and the trim edge side ventilation passage C different, the flow velocity of rainwater changes, causing turbulence, and rainwater is less likely to flow into the ventilation passage A.
In addition, according to this embodiment, rainwater rising up the edge-side ventilation passage C can be made to collide with the ventilation member bottom plate 21, making it difficult for the rainwater to flow into the ventilation passage A.
本実施例による外壁材上端換気装置は、換気部材前面板２２は外壁材９９より前方に位置させ、換気部材後面板２４は外壁材９９より後方に位置させている。
従って、換気通路Ａの奥行寸法を大きくでき、換気通路Ａに流入した雨水を換気通路Ａに留めることができ、屋内に雨水が侵入することはない。
In the exterior building material upper end ventilation device according to this embodiment, the ventilation member front panel 22 is positioned in front of the exterior building material 99 , and the ventilation member rear panel 24 is positioned behind the exterior building material 99 .
Therefore, the depth dimension of the ventilation passage A can be increased, and rainwater flowing into the ventilation passage A can be retained in the ventilation passage A, preventing the rainwater from entering the interior of the building.
また、本実施例による外壁材上端換気装置は、内部防水壁２５を、換気部材天面板２３の後端から垂下させ、換気部材後面板２４を、換気部材底面板２１の後端から立ち上げており、換気孔２７から換気通路Ａに流入する空気は、換気部材前面板２２と内部防水壁２５との間Ａ１では下方に向けた流れとなり、内部防水壁２５と換気部材後面板２４との間Ａ２では上方に向けた流れとなる。
このように、雨水は、内部防水壁２５によって下方に向けた流れの後に上方に向けた流れとなるために、屋内に侵入することはない。
なお、本実施例による外壁材上端換気装置では、外気は、換気部材側通気路Ｄから換気通路Ａを通って建造物の内部に給気される。
In addition, in the exterior wall material upper end ventilation device of this embodiment, the internal waterproof wall 25 hangs down from the rear end of the ventilation member top panel 23 and the ventilation member rear panel 24 rises up from the rear end of the ventilation member bottom panel 21, and the air flowing into the ventilation passage A from the ventilation hole 27 flows downward between the ventilation member front panel 22 and the internal waterproof wall 25 A1, and flows upward between the ventilation member front panel 22 and the internal waterproof wall 25 A2.
In this way, rainwater flows downward and then upward due to the internal waterproof wall 25, and therefore does not enter the building.
In the exterior building material top end ventilation device according to this embodiment, outside air is supplied to the inside of the building through the ventilation passage A from the ventilation member side air passage D.

本実施例による外壁材上端換気装置は、見切縁上面板１１の奥行寸法Ｌ１を外壁材８４の厚さＬ２よりも大きくすることで、見切縁前面板１２と外壁材８４との間に水切空間Ｂを形成している。

FIG. 4 is an enlarged cross-sectional view of a main portion of FIG.
In this embodiment, the exterior wall material upper end ventilation device forms a water drainage space B between the edge front panel 12 and the exterior wall material 84 by making the depth dimension L1 of the edge upper panel 11 larger than the thickness L2 of the exterior wall material 84.
In addition, in the exterior wall material upper end ventilation device according to this embodiment, the front end of the trim top plate 11 protrudes forward from the front end of the ventilation member bottom plate 21. A trim side ventilation passage C is formed between the trim front plate 12 and the hanging member 85b, and a ventilation member side ventilation passage D is formed between the ventilation member front plate 22 and the hanging member 85b.
Therefore, the ventilation member side air passage D has a larger air passage depth dimension than the trim side air passage C, and the ventilation member side air passage D and the trim side air passage C have different air passage depth dimensions.
本実施例によれば、第１防水パッキン３１により見切縁上面板１１と換気部材底面板２１との間の防水を行い、第２防水パッキン３２により見切縁後面板１３の前面と外壁材８４との間の防水を行うため、外壁材８４の上端と換気部材２０との間での防水性能を確保でき、外壁材８４に沿って上昇する雨水は、水切空間Ｂに導かれ、見切縁前面板１２に沿って落下するために、換気部材前面板２２には導かれず、換気孔２７から換気通路Ａに流入しないので防水性能に優れる。 According to this embodiment, the first waterproof packing 31 provides waterproofing between the trim top panel 11 and the ventilation member bottom panel 21, and the second waterproof packing 32 provides waterproofing between the front surface of the trim rear panel 13 and the exterior wall material 84, ensuring waterproofing between the upper end of the exterior wall material 84 and the ventilation member 20. Rainwater rising along the exterior wall material 84 is guided to the drainage space B and falls along the trim front panel 12, so it is not guided to the ventilation member front panel 22 and does not flow into the ventilation passage A from the ventilation hole 27, resulting in excellent waterproofing.
また、本実施例によれば、雨水は、見切縁側通気路Ｃ及び換気部材側通気路Ｄを上昇しなければ換気孔２７に至らないため、換気通路Ａに流入しにくく、更に防水性に優れる。

Furthermore, according to this embodiment, rainwater cannot reach the ventilation hole 27 unless it rises through the trim side ventilation passage C and the ventilation member side ventilation passage D, so that the rainwater is less likely to flow into the ventilation passage A, and the waterproofing is further improved.
In addition, according to this embodiment, by making the ventilation passage depth dimensions of the ventilation member side ventilation passage D and the trim edge side ventilation passage C different, the flow velocity of rainwater changes, generating turbulence, and rainwater is less likely to flow into the ventilation passage A.
本実施例による外壁材上端換気装置は、換気部材前面板２２は外壁材８４より前方に位置させ、換気部材後面板２４は外壁材８４より後方に位置させている。
従って、換気通路Ａの奥行寸法を大きくでき、換気通路Ａに流入した雨水を換気通路Ａに留めることができ、屋内に雨水が侵入することはない。
In the exterior building material upper end ventilation device according to this embodiment, the ventilation member front panel 22 is positioned in front of the exterior building material 84 , and the ventilation member rear panel 24 is positioned behind the exterior building material 84 .
Therefore, the depth dimension of the ventilation passage A can be increased, and rainwater flowing into the ventilation passage A can be retained in the ventilation passage A, preventing the rainwater from entering the interior of the building.
また、本実施例による外壁材上端換気装置は、内部防水壁２５の上端を内部防水壁２５の下端よりも換気部材前面板２２に近接させており、換気孔２７から流入する雨水を換気部材後面板２４に至ることを防止できる。
なお、本実施例による外壁材上端換気装置では、通気胴縁８３を上昇した空気は、換気通路Ａを通過して換気孔２７から排出される。
In addition, in the exterior wall material upper end ventilation device of this embodiment, the upper end of the internal waterproof wall 25 is closer to the ventilation member front panel 22 than the lower end of the internal waterproof wall 25, thereby preventing rainwater flowing in from the ventilation hole 27 from reaching the ventilation member rear panel 24.
