Description

本発明は、軒先の鼻隠しに通気孔を備えた鼻隠し化粧板を取り付け、通気孔を通して家屋の屋根裏の空間を換気することができるように構成された軒先構成体に関する。 TECHNICAL FIELD The present invention relates to an eaves structure configured to attach a ventilated nose cover to the eaves at the eaves and ventilate the space in the attic of a house through the air holes.

鼻隠し化粧板に通気孔を設けて屋根裏の空間を換気することができるようにした軒先構成体として、例えば図１０に示されるように、鼻隠し１００に取り付けられる鼻隠し化粧板１０１の取り付け面部１０２の下端部を後方へ屈曲して鼻隠し１００の下方に換気室１０３を形成し、この換気室１０３の前面に通気孔１０４を設けて外気が換気室１０３内を通って屋根裏空間１０５へと流入するように設けるとともに、換気室１０３内に当該室内の上方の空間を前後に仕切る遮蔽板１０６を配置し、この遮蔽板１０６の下端部に加熱発泡材１０７を装着して、火災発生時に加熱発泡材１０７が膨張することで換気室１０３内の通気路を遮断し、屋根裏空間１０５に火炎や熱風が入り込むことを防ぐようにした構造のものが知られている。 For example, as shown in FIG. 10, as an eaves tip structure in which ventilating holes are provided in the nasal cavity cover to ventilate the space in the attic, the attachment surface portion of the nasal cover 100 to be attached to the nasal cover 100 The lower end portion of 102 is bent backward to form a ventilation room 103 under the nose cover 100, and a vent hole 104 is provided on the front of the ventilation room 103 so that the outside air passes through the ventilation room 103 to the attic space 105. A shielding plate 106 is provided so as to flow in, and the upper space of the room is divided back and forth in the ventilation chamber 103, and a heating foam material 107 is attached to the lower end of the shielding plate 106 to heat when a fire occurs. There is known a structure having a structure in which the air passage in the ventilation chamber 103 is shut off by the expansion of the foam material 107 to prevent the flame and the hot air from entering the attic space 105.

図示した軒先構成体によれば、通気孔１０４から外気を取り入れて屋根裏空間１０５を十分に換気することができ、火災の際には熱を受けて膨張した加熱発泡材１０７が換気室１０３内の通気路を遮断することで通気孔１０４からの外気の流入を遮断し、火炎や熱風が屋根裏へと入り込んで家屋が延焼することを効果的に防止することが可能である（例えば特許文献１，２参照）。 According to the illustrated eaves structure, outside air can be taken in from the air vent 104 to sufficiently ventilate the attic space 105, and in the case of a fire, the heated foam material 107 which has been expanded by receiving heat is in the ventilation chamber 103. By blocking the air passage, it is possible to shut off the inflow of the outside air from the air hole 104, and effectively prevent the fire and fire from entering the attic and the house from spreading fire (for example, patent documents 1, 1) 2).

近時、軒の出がない或いは軒の出を短く納めた、いわゆる「軒ゼロ住宅」が広く採用されてきている。「軒ゼロ住宅」は都市部の市街地などの狭小地に建てられる家屋への採用が比較的多い。そのような住宅密集地域では、火災が起きたときに出火元の家屋から隣接する家屋に火が燃え広がって被害を拡大させやすいことから、隣接する家屋との間に庭や植栽用の空間を確保することのできる郊外に建てる家屋よりも、家屋の防火性能が高いことが必要とされる。 In recent years, so-called "zero-free houses", in which there are no eaves or short for eaves, have been widely adopted. There are a relatively large number of “eave zero houses” adopted for houses built on narrow lands such as urban areas in urban areas. In such a densely populated area, when a fire occurs, the fire spreads from the house where the fire started to the adjacent house and it is easy to spread the damage, so there is a space for gardening and planting between the adjacent houses. It is required that the fire performance of the house be higher than that of a house built in the suburbs which can be secured.

前述の軒先構成体は、屋根裏空間を換気する機能と火災時に外気と火炎を遮断する機能はともに良好であるものの、これを住宅密集地域の「軒ゼロ住宅」の家屋に適用する場合、両機能をより向上させた構造に設けられていること、とりわけ火災時には通気孔から屋根裏空間に至る通気路を確実に短時間で遮断することのできる構造に設けられていることが、当該家屋の防火性能を高める上で肝要である。 The above-mentioned eaves-end construction has both a function to ventilate the attic space and a function to shut off the outside air and flame at the time of fire, but both functions when applying this to the house of "zero zero residence" in densely populated areas. The fire protection performance of the house is that it is provided in a structure that can shut off the air passage from the air vent to the attic space in a short time in a short time, especially in the event of a fire. It is important to raise the

前記軒先構成体における火災時の通気路遮断機能を高める方策としては、例えば熱せられた外気を受けて膨張する加熱発泡材の設置量を多くしたり、通気路を狭くし或いは通気孔の数を減らしたりすることが考えられる。
然しながら、前者の単に加熱発泡材の設置量を多くしただけでは、設置位置が適切でないと、換気機能を低下させたり膨張するのに時間を要したりしてしまうことにもなりかねず、後者では換気機能が損なわれることは明らかである。また、通気路上に適切な量の加熱発泡材が設置されていたとしても、これを取り囲む通気路の内面形状、つまり換気室の形状によっては、膨張した加熱発泡材と換気室内面の間に隙間ができるなどして、通気孔から流入する外気の遮断が不十分となる虞もある。
火災時の通気路の遮断をより確実にするには、通気路内面を形成する換気室の形状を改良した上で加熱発泡材の設置位置の精査が必要である。また、狭小地に建てられることと相俟って軒先構成体を取り付ける軒先部分の工事は簡易な作業で行える構造とする必要がある。 As a measure for enhancing the air passage blocking function at the time of fire in the eaves tip structure, for example, the installation amount of the heating foam material which expands in response to the heated outside air is increased, the air passage is narrowed, or the number of air holes is increased. It is possible to reduce it.
However, simply increasing the installation amount of the heating foam material in the former may lead to a decrease in the ventilation function or a time required for expansion if the installation position is not appropriate. It is obvious that the ventilatory function is impaired. In addition, even if an appropriate amount of heated foam is installed on the air passage, depending on the inner surface shape of the air passage surrounding it, that is, depending on the shape of the ventilation room, a gap between the expanded heated foam and the ventilated room surface. There is also a possibility that the blocking of the outside air flowing from the vent may be insufficient.
In order to ensure the blocking of the air passage in the event of a fire, it is necessary to improve the shape of the ventilating chamber forming the inner surface of the air passage and to examine the installation position of the heating foam. In addition, combined with being built in a small area, the construction of the eaves to which the eaves structure is attached needs to be a structure that can be performed by simple work.

本発明は従来の技術が有するこのような問題点に鑑み、屋根裏空間を換気するための通気孔を備えた鼻隠し化粧板を鼻隠しに取り付けて構成される軒先構成体において、鼻隠しの下方に設ける換気室の形状の改良と加熱発泡材の取り付け位置の選定により、換気機能を低下させることなく、火災時には外気の通気路が確実に遮断されるようにして家屋の防災性能を高めることを課題とする。
また、本発明は、換気機能及び火災時に外気と火炎の進入を阻止する機能がともに良好な軒先構成体を、「軒ゼロ住宅」の軒先に簡易な工事で取り付けることができるようにすることを課題とする。 In view of such problems with the prior art, the present invention provides an eaves-end structure configured by attaching to a nose hide a decorative board provided with a vent for ventilating an attic space. By improving the shape of the ventilation room provided in and selecting the mounting position of the heating foam material, the ventilation path of the outside air is surely blocked at the time of fire without lowering the ventilation function, and the disaster prevention performance of the house is enhanced. It will be an issue.
In addition, the present invention makes it possible to attach an eaves-end structure having both a ventilation function and a function for preventing the entrance of external air and flame at the time of fire so as to be able to attach the eaves of "zero-eave house" with a simple construction. It will be an issue.

前記課題を解決するため本発明は、鼻隠しの前面に重なる前側面部と前側面部の下端から鼻隠しの下方へ張り出した下側面部を有する鼻隠し化粧板を鼻隠しに取り付けて、鼻隠しの下方に屋根裏空間に通じる換気室を形成し、前記鼻隠し化粧板の前側面部に形成された通気孔から換気室内に進入した外気が屋根裏空間へ流入するように構成された軒先構成体であって、
前記換気室内が、換気室内の空間を上下に仕切る横仕切り面部と前後に仕切る縦仕切り面部を交互に複数配置してなる仕切り部材によって外気の流入経路の上流側の空間と下流側の空間に区画され、且つ前記縦仕切り面部の内の少なくとも一の縦仕切り面部に形成された通気孔によって上流側と下流側の空間を連通させてあるとともに、
前記鼻隠し化粧板に形成された通気孔に近接する当該化粧板の下側面部上面と、前記縦仕切り面部に形成された通気孔に近接する横仕切り面部の上面に加熱発泡材がそれぞれ取り付けられた構成を有することを特徴とする。 In order to solve the above problems, the present invention attaches a nose cover to a nose cover having a front side that overlaps the front of the nose cover and a lower side that protrudes downward from the lower end of the front side from the lower end of the front side. An eaves structure configured to form a ventilation room below the concealed space to the attic space, and allow outside air entering the ventilation room from the air vent formed in the front side of the nose hide decorative board to flow into the attic space And
The ventilating room is divided into a space on the upstream side and a space on the downstream side of the inflow path of the outside air by a partition member in which a horizontal partition surface part partitioning the space in the ventilation chamber up and down and a vertical partition surface part partitioning the front and back alternately And communicating the spaces on the upstream side and the downstream side by vent holes formed in at least one of the vertical partition surface portions of the vertical partition surface portions,
A heating foam is attached to the upper surface of the lower side surface portion of the decorative plate adjacent to the vent hole formed in the nose concealed decorative plate and the upper surface of the horizontal partition surface portion adjacent to the vent hole formed in the vertical partition surface portion It is characterized by having the following configuration.

また、本発明は、前記換気室内が、換気室内の空間を上下に仕切る横仕切り面部と前後に仕切る縦仕切り面部を交互に複数配置してなる仕切り部材によって外気の流入経路の上流側の空間と下流側の空間に区画され、且つ前記横仕切り面部の内の少なくとも一の横仕切り面部に形成された通気孔によって上流側と下流側の空間を連通させてあるとともに、
前記鼻隠し化粧板に形成された通気孔に近接する当該化粧板の下側面部上面と、前記通気孔が形成された横仕切り面部と上下に対向配置されたに横仕切り面部の上面に加熱発泡材がそれぞれ取り付けられた構成を有することを特徴とする。 Further, according to the present invention, a space on the upstream side of the inflow path of the outside air is formed by a partition member in which the ventilating room is alternately provided with a horizontal partition surface part partitioning the space in the ventilation chamber up and down and a vertical partition surface part partitioning the front and back. Upstream and downstream spaces are communicated with each other by vent holes formed in the downstream space and formed in at least one of the horizontal partition surface portions,
The upper surface of the lower side surface portion of the decorative plate adjacent to the air vent formed in the nose concealed decorative plate, and the upper surface of the horizontal partition surface portion vertically opposed to the horizontal partition surface portion where the air vent is formed It is characterized in that it has a configuration in which the materials are respectively attached.

これによれば、鼻隠し化粧部板に形成された通気孔から外気が換気室内に進入し、さらに仕切り部材に形成された通気孔を通って屋根裏の空間へと流入する。外気の流入により、屋根裏空間内で空気が滞留することを防ぎ、当該空間内に流入してきた外気によって換気することができる。
換気室内が仕切り部材によって、外気流入経路の上流側と下流側の空間、つまり鼻隠し化粧板に形成された通気孔に面する空間と屋根裏空間へと通じる空間の二つの空間に区画されているので、強風時に通気孔から外気が換気室内に勢いよく進入しても、仕切り部材に衝突して勢いが削がれるため、流入した外気が屋根裏の空間まで一気に入り込むようなことはない。
また、鼻隠し化粧板に形成された通気孔に近接した位置に加熱発泡材が取り付けられ、さらに仕切り部材に形成された通気孔に近接した位置にも加熱発泡材が取り付けられ、換気室内の通気路上に少なくとも二つの加熱発泡材が取り付けてあるので、隣接する家屋に火災が発生し、それによる火炎や熱風が通気孔から換気室内に進入したときには、熱せられた各加熱発泡材が膨張することで屋根裏の空間に通ずる通気路が完全に遮断され、火炎や熱風が換気室内から屋根裏へ入り込むことを防止して家屋が延焼することを防ぐことができる。加熱発泡材は、鼻隠し化粧板に形成された通気孔から換気室を通じて屋根裏空間に至る通気路に沿って、少なくとも二つを適宜な間隔を空けて配置することが好ましい。換気機能を損なわず且つ材料コストが嵩まなければ三つ以上を配置してもよい。 According to this, outside air enters the ventilating room from the vent hole formed in the nasal cavity cosmetic part plate, and further flows into the attic space through the vent hole formed in the partition member. By the inflow of the outside air, air can be prevented from staying in the attic space, and ventilation can be performed by the outside air flowing into the space.
The ventilation room is divided by the partition member into two spaces of the space on the upstream side and the downstream side of the outside air inflow path, that is, the space facing the vent formed in the nose concealed decorative plate and the space leading to the attic space Therefore, even if the outside air rushes into the ventilating room from the air vents in a strong wind, it collides with the partition member and the momentum is reduced, so the inflowing outside air does not enter the space of the attic all at once.
In addition, the heating foam is attached at a position close to the vent formed in the nose concealed decorative board, and the heat foam is also attached at a position proximate to the vent formed in the partition member. Because at least two heating foams are attached on the street, a fire occurs in an adjacent house, and when the fire or hot air resulting from it fires from the vent into the ventilation room, the heated heating foams expand. The air passage leading to the attic space is completely shut off, and it is possible to prevent the fire and the fire from entering the attic from the ventilated room and prevent the house from spreading fire. It is preferable to arrange at least two heating foams at appropriate intervals along the air passage extending from the air vent formed in the blindfold decorative board to the attic space through the ventilation room. Three or more may be arranged if the ventilation function is not impaired and the material cost is not increased.

前記構成の軒先構成体において、仕切り部材は、その前端部に鼻隠し化粧板とともに鼻隠しの前面に固定される固定面部、後端部に家屋の外壁に固定されて前記鼻隠し化粧板の下側面部の端部を支持する支持面部をそれぞれ備え、換気室内に取り付けた状態で鼻隠し化粧板の下側面部の上方に、横仕切り面部で仕切られた前後方向に伸びた通気路と縦仕切り面部で仕切られた上下方向に伸びた通気路を連ねてなる断面逆Ｌ字形の通気路を形成するように設けられていることが好ましい。
これによれば、鼻隠し化粧板に形成された通気孔から換気室に進入した外気は、換気室の上流側の空間内で、前後方向に伸びた通気路に流入し、横仕切り面部の表面を伝って換気室後方へと流れ、そのまま前後方向の通気路に続く上下方向に伸びた通気路に流入し、縦仕切り面部の表面を伝って上昇し、縦仕切り面部に形成された通気孔を通って換気室の下流側の空間に進入し、さらに上昇して屋根裏の空間へと流入する。
すなわち、換気室の上流側の通気路が、ジグザグ状或いはクランク状に屈曲した断面逆Ｌ字形の複雑な経路に設けられ、外気が換気室内を通って屋根裏空間に到達するまでに時間を要するようになっている。そのため、火災の際に熱せられた外気が換気室内に進入しても、前記複雑な経路を通って屋根裏空間に流入するまでに時間を要し、高温な外気を受けて膨張する加熱発泡材により通気路が完全に遮断される前に、外気が通気路を通って一気に屋根裏空間へと流入することはなく、熱風や火炎が屋根裏へ入り込むことを確実に防ぐことができる。 In the eaves-ends structure of the above configuration, the partition member is fixed to the front end portion of the fixed surface portion fixed to the front of the nose hide with the nose hide decorative plate, fixed to the outer wall of the house at the rear end portion under the nose hide decoration plate Each has a support surface that supports the end of the side and is mounted in a ventilated room above the lower surface of the decorative panel for the nose, which extends in the front-rear direction and divided by the horizontal partition surface It is preferable to provide an air passage having an inverted L-shaped cross section, which is formed by connecting vertically extending air passages separated by surface portions.
According to this, outside air which has entered the ventilation room from the ventilation hole formed in the nasal cavity decorative board flows into the ventilation path extending in the front-rear direction in the space on the upstream side of the ventilation room, and the surface of the horizontal partition surface Flow to the rear of the ventilation room, and flow directly into the vertically extending vents that follow the vents in the front-back direction, ascend along the surface of the vertical partition surface and rise through the vents formed in the vertical partition surface. It passes through to the space on the downstream side of the ventilation room, and further rises to the space of the attic.
That is, the air passage on the upstream side of the ventilating chamber is provided in a complicated route of a cross-sectional inverted L-shape bent in a zigzag or crank shape, and it takes time for outside air to pass through the ventilating chamber to reach the attic space. It has become. Therefore, even if the outside air heated in the event of a fire enters the ventilating room, it takes time to flow into the attic space through the complex route, and it is heated by the heated foam that receives the high-temperature outside air and expands. Before the air passage is completely shut off, the outside air does not rush into the attic space through the air passage, and hot air and flame can be reliably prevented from entering the attic.

前記構成の軒先構成体において、鼻隠し化粧板の下側面部上面に取り付けられた加熱発泡材の直上であって前側面部に形成された通気孔と対面する位置に、仕切り部材の固定面部の下端部から後方へ屈曲した横仕切り面部が配置された構成を有することが好ましい。
これによれば、換気室への外気の進入口である通気孔に近接して取り付けられた加熱発泡材の直上に仕切り部材の横仕切り面部を配置して、加熱発泡材上方の外気の通気路を狭めてあるので、火災時に流入する熱せられた外気は、加熱発泡材上の狭い通路を通過して加熱発泡材の表面に接する。狭い通路を通過することで加熱発泡材を熱する外気の密度が大きくなり、多量の外気が加熱発泡材に接して加熱せしめ、加熱発泡材を短時間で効率的に膨張させて、外気の進入口となる通気路を確実に遮断することが可能である。 In the eaves-ends structure of the above configuration, the fixed surface portion of the partition member at a position immediately above the heating foam attached to the upper surface of the lower side surface portion of the nose hide decorative plate and facing the vent formed in the front side surface portion. It is preferable to have the structure by which the horizontal partition surface part bent from the lower end part back is arrange | positioned.
According to this, the lateral partition surface portion of the partition member is disposed immediately above the heating foam attached close to the ventilation hole which is an entrance of the outside air to the ventilation room, and the ventilation path of the outside air above the heating foam The heated outside air coming in at the time of fire passes through the narrow passage on the heating foam and contacts the surface of the heating foam. By passing through the narrow passage, the density of the outside air that heats the heated foam material is increased, and a large amount of outside air is brought into contact with the heated foam material to heat it, expanding the heated foam material efficiently in a short time It is possible to reliably shut off the venting channel which is the mouth.

また、前記構成の軒先構成体において、仕切り部材は、出幅の異なる軒先への取り付けに対応できるように、その固定面部と支持面部間の幅を拡張し得るように形成してあることが好ましく、また、部材コストを安価にし、家屋の軒先に簡易な工事で取り付けることができるようにするため、一枚の鋼板を折り曲げ加工するなどして形成されていることが好ましい。 Further, in the eaves tip structure of the above configuration, the partition member is preferably formed so as to be able to expand the width between the fixing surface portion and the support surface portion so as to be able to correspond to attachment to eaves tips having different projecting widths In addition, in order to reduce the cost of the members and to be able to be attached to the eaves of a house by a simple construction, it is preferable to form by bending a single steel plate.

A support surface portion 62 to be fixed is provided, and a horizontal partition surface portion 63 partitioning the space in the ventilation chamber 7 up and down and a vertical partition surface portion 64 partitioning front and rear are alternately arranged between the two surface portions.

詳しくは、図１及び図３に示されるように、仕切り部材６は、その固定面部６１が鼻隠し１に取り付けられたときに鼻隠し１の前面下端よりも下方へ突出する長さ（高さ）に設けられ、固定面部６１の下端から後方へ横仕切り面部６３が略直角に折れ、この横仕切り面部６３の後端から上方へ縦仕切り面部６４が略直角に折れ、さらにこの縦仕切り面部６４の上端から後方へ横仕切り面部６３、縦仕切り面部６４及び横仕切り面部６３が順次連なって支持面部６２に至る形状に設けられ、前記固定面部６１の下端から折れた横仕切り面部６３の上面に加熱発泡材８を接着固定して取り付け、この横仕切り面部６３の後端から折れた縦仕切り面部６４に通気孔６５を形成してある。前記支持面部６２の端部は前方へ適宜な長さ張り出し、その先端部を適宜な幅だけ上面に折り重ねてある。 Specifically, as shown in FIG. 1 and FIG. 3, the partition member 6 has a length (height) that protrudes downward below the front lower end of the nose lid 1 when the fixed surface portion 61 is attached to the nose lid 1. And the horizontal partition surface 63 is broken at a substantially right angle from the lower end of the fixed surface 61 to the rear, and the vertical partition surface 64 is broken at a substantially right angle from the rear end of the horizontal partition surface 63. The horizontal partition surface 63, the vertical partition surface 64, and the horizontal partition surface 63 are sequentially connected in series from the upper end to the support surface 62 and heated to the upper surface of the horizontal partition surface 63 broken from the lower end of the fixed surface 61. The foam material 8 is adhesively fixed and attached, and an air vent 65 is formed in the vertical partition surface 64 that is broken from the rear end of the horizontal partition surface 63. The end of the support surface portion 62 protrudes forward for an appropriate length, and its tip end is folded on the upper surface by an appropriate width.

また、本形態の仕切り部材６は、図３に示されるように、一枚の鋼板を折り曲げ加工により、固定面部６１と支持面部６２の間に横仕切り面部６３と縦仕切り面部６４を交互に配置して、恰も山部と谷部を交互に配置した蛇腹形の側面視形状を呈するように形成してあるので、図４に示されるように、自身の弾性を利用して固定面部６１と支持面部６２間の幅をある程度伸長させることが可能であり、出幅が大きな軒先に前記固定面部６１と支持面部６２間の幅を伸長させて取り付けることで、屋根の勾配が異なる家屋の軒先に対応して取り付けることができるようになっている。 In addition, as shown in FIG. 3, in the partition member 6 of this embodiment, the horizontal partition surface portions 63 and the vertical partition surface portions 64 are alternately arranged between the fixed surface portion 61 and the support surface portion 62 by bending a single steel plate. Since the ridges and valleys are alternately formed to have a bellows-like side view, as shown in FIG. It is possible to extend the width between the surface portions 62 to some extent, and by extending the width between the fixed surface portion 61 and the support surface portion 62 to the eaves point with a large extension width, the roof slope corresponds to eaves of different houses. Can be attached.

仕切り部材６は、その固定面部６１が鼻隠し化粧板５の前側面部５１とともに鼻隠し１の前面に、支持面部６２が外壁２にそれぞれ取りつけられ、鼻隠し化粧板５の下側面部５２を支持面部６２上に重ねて上方折れ面部５２ｂを支持面部６２上に差し入れることで、鼻隠し化粧板５の後端部が支持面部６２に接続して支持されるように設けてあり、鼻隠し化粧板５と仕切り部材６の支持面部６２が鼻隠し１の下方で一続きになることで、屋根裏空間３に通じていて内部が仕切り部材６により二つの空間に仕切られた換気室７を鼻隠し１の下方に形成し、鼻隠し化粧板５の前面に設けた通気孔５３から外気を換気室７内に取り入れ、取り入れた外気が仕切り部材６に形成された通気孔６５を通って屋根裏空間３へと流入し、これにより屋根裏空間３が換気されるようになっている。 In the partition member 6, the fixed surface portion 61 is attached to the front surface of the nose hide 1 together with the front side surface portion 51 of the nose hide decorative plate 5, and the support surface portion 62 is attached to the outer wall 2. By inserting the upper broken surface portion 52b on the support surface portion 62 by overlapping the support surface portion 62, the rear end portion of the nose hide decorative plate 5 is provided so as to be connected to and supported by the support surface portion 62. The decorative plate 5 and the support surface portion 62 of the partition member 6 are continuous in the lower part of the nose lid 1 to communicate with the attic space 3 and have the ventilating chamber 7 whose inside is partitioned into two spaces by the partition member 6 Outside air is taken into the ventilation room 7 from the air vents 53 formed under the cover 1 and provided on the front face of the cover plate 5, and the taken outside air passes through the air vents 65 formed in the partition member 6 to form the attic space. It flows into 3 and the attic sky by this 3 is adapted to be ventilated.

また、図１に示されるように、換気室７内が仕切り部材６により仕切られた状態で、鼻隠し化粧板５の下側面部５２の上方に、横仕切り面部６３で仕切られた前後方向に伸びた通気路と、縦仕切り面部６４で仕切られた上下方向に伸びた通気路の通気路を連ねてなる断面逆Ｌ字形の通気路が形成され、通気孔５３から換気室７内に進入した外気は、換気室７の上流側で前後方向に伸びた通気路に流入し、横仕切り面部６３の表面を伝って換気室７後方へと流れ、そのまま前後方向の通気路に続く上下方向に伸びた通気路に流入し、縦仕切り面部６４の表面を伝って上昇し、縦仕切り面部６４に形成された通気孔６５を通って換気室７の下流側の空間に進入し、さらに上昇して屋根裏空間３へと流入し、外気が換気室７内を通って屋根裏空間３に到達するまでに時間を要するように設けてある。 Further, as shown in FIG. 1, in the front-rear direction divided by the horizontal partition surface portion 63 above the lower side surface portion 52 of the nose hide decorative plate 5 in a state where the inside of the ventilation chamber 7 is partitioned by the partition member 6 An air passage having an L-shaped cross section formed by connecting the air passage of the extended air passage and the air passage of the vertically extended air passage divided by the vertical partition surface portion 64 was formed Outside air flows into an air passage extending in the front and rear direction on the upstream side of the ventilation chamber 7, and flows along the surface of the lateral partition surface portion 63 to flow rearward of the ventilation chamber 7, and extends in the vertical direction following the air passage in the front and back direction. Flows into the ventilating passage, rises along the surface of the vertical partition surface 64, passes through the vent holes 65 formed in the vertical partition surface 64, enters the space on the downstream side of the ventilation chamber 7, and further rises to the attic. The air flows into the space 3 and the outside air passes through the ventilating chamber 7 to the attic space 3 It is provided so as to take time to reach.

また、図１に示されるように、換気室７内が仕切り部材６により仕切られた状態で、鼻隠し化粧板５の下側面部５２上面に取り付けられた加熱発泡材８の直上であって前側面部５１に形成された通気孔５３と対面する位置に、仕切り部材６の固定面部６１の下端部から後方へ屈曲した横仕切り面部６３が配置され、前記加熱発泡材８の上方の通気路が下方へ張り出した横仕切り面部６３によって狭められるように設けてある。 Further, as shown in FIG. 1, in a state where the inside of the ventilation chamber 7 is partitioned by the partition member 6, the heating foam material 8 mounted directly on the upper surface of the lower side surface 52 of the nose concealed decorative board 5 is A horizontal partition surface 63 bent from the lower end of the fixed surface 61 of the partition member 6 backward is disposed at a position facing the air vent 53 formed in the side surface 51, and the air passage above the heating foam 8 is It is provided so as to be narrowed by the horizontal partition surface portion 63 projecting downward.

これらの部材により構成される本形態の軒先構成体４の軒先への取り付けは、先ず、仕切り部材６の固定面部６１を鼻隠し１の前面に接合して仮固定した状態、支持面部６２を外壁２に接合し、取り付け位置を調整したならば、支持面部６２を固着具９で外壁２に留め付けて固定する。 The attachment to the eaves tip of the eaves tip structure 4 of the present embodiment constituted by these members is first a state in which the fixing face part 61 of the partition member 6 is joined and temporarily fixed to the front face of the nose hide 1, the support face 62 is an outer wall After bonding to 2 and adjusting the mounting position, the support surface portion 62 is fastened and fixed to the outer wall 2 with the fasteners 9.

次いで、鼻隠し化粧板５の前側面部５１を鼻隠し１に仮固定された仕切り部材６の固定面部６１に重ねるとともに、下側面部５２先端の上方折れ面部５２ｂを前記支持面部６２の上方に差し入れて下側面部５２の後端部を支持面部６２に接続し、鼻隠し１の前面に重なり合った仕切り部材６の固定面部６１と鼻隠し化粧板５の前側面部５１を、固着具９を打ち込んで鼻隠し１に固定することで、軒先構成体４の取り付けが完了する。その後、屋根を工事し、鼻隠し化粧板５の前側面部５１に雨樋を取り付けるなどして家屋の軒先廻りの造作が完了する。 Then, while overlapping the front side surface 51 of the nose hide decorative plate 5 on the fixed surface 61 of the partition member 6 temporarily fixed to the nose lid 1, the upper bending surface 52 b of the tip of the lower side 52 is above the support surface 62. The fixed surface portion 61 of the partition member 6 and the front side surface portion 51 of the nose hide decorative plate 5 which were inserted by connecting the rear end portion of the lower side surface portion 52 to the support surface portion 62 and overlapping the front surface of the The attachment of the eaves-end structure 4 is completed by driving in and fixing it to the nose hide 1. Thereafter, the roof is constructed, and a gutter is attached to the front side portion 51 of the cover plate 5 to complete the construction of the eaves of the house.

本形態の軒先構成体４によれば、鼻隠し化粧板５に形成された通気孔５３から外気が換気室７内に進入し、さらに仕切り部材６に形成された通気孔６５を通って屋根裏空間３へと流入し、外気の流入により屋根裏空間３内で空気が滞留することを防ぎ、当該空間内に流入してきた外気によって換気することができる。
換気室７内が仕切り部材６によって外気流路の上流側と下流側の空間に区画されているので、強風時に通気孔５３から外気が換気室７内に勢いよく進入しても、仕切り部材６に衝突して勢いが削がれるため、流入した外気が屋根裏空間３まで一気に入り込むようなことはない。 According to the eaves tip structure 4 of the present embodiment, the outside air enters the ventilation chamber 7 from the vent hole 53 formed in the nose hide decorative plate 5 and further passes through the vent hole 65 formed in the partition member 6 to form the attic space. It can flow into 3 and prevent the air from staying in the attic space 3 due to the inflow of the outside air, and can be ventilated by the outside air flowing into the space.
Since the inside of the ventilating chamber 7 is divided by the partitioning member 6 into the spaces on the upstream side and the downstream side of the external air flow path, the partitioning member 6 can be ventilated even if the outside air rushes into the ventilation chamber 7 from the vent hole 53 at strong wind. There is nothing that rushes into the attic space 3 because the momentum is reduced by the collision.

また、鼻隠し化粧板５に形成された通気孔５３に近接した位置に加熱発泡材８が取り付けられ、また、仕切り部材６の縦仕切り面部６４に形成された通気孔６５に近接した、横仕切り面部６３の上面にも加熱発泡材８が取り付けられているので、隣接する家屋に火災が発生し、それによる火炎や熱風が通気孔５３から換気室７内に進入したときには、両加熱発泡材８が流入外気の熱を受けて膨張することで通気孔５３と通気孔６５をそれぞれ塞ぎ、屋根裏空間３に通ずる換気室７内の外気の通気路を確実に遮断して、火炎や熱風が換気室７から屋根裏空間３へ入り込むことを確実に防止して家屋が延焼することを防ぐことが可能である。 In addition, the heating foam material 8 is attached at a position close to the air vent 53 formed in the nose concealed decorative board 5, and the horizontal partition close to the air vent 65 formed in the vertical partition surface portion 64 of the partition member 6. Since the heating foam 8 is attached also to the upper surface of the surface portion 63, a fire occurs in the adjacent house, and when the fire or hot air resulting from it fires from the air vent 53, both heating foams 8 The heat is expanded by receiving the heat of the inflowing air to close the air vent 53 and the air vent 65, and reliably block the air vent in the ventilating chamber 7 leading to the attic space 3, and the flame and the hot air are ventilated. It is possible to prevent the house from spreading fire by reliably preventing entry into the attic space 3 from 7.

この場合、換気室７内の外気上流側の通気路は、断面逆Ｌ字形の複雑な経路に設けられているので、外気が換気室７内を通って屋根裏空間３に到達するまでに時間を要し、高温な外気を受けて膨張する加熱発泡材８，８により通気路が完全に遮断される前に、外気が通気路を通って一気に屋根裏空間３へと流入することはない。また、通気孔５３の近傍に取り付けられた加熱発泡材８は、その上方に仕切り部材６の横仕切り面部６３が位置し、当該加熱発泡材８上方の外気の通気路を狭めてあるので、通気孔５３から進入する熱せられた外気を受けて短時間で膨張せしめられ、通気孔５３を効率的且つ短時間で塞ぐことが可能である。 In this case, since the air passage on the upstream side of the outside air in the ventilation room 7 is provided in a complicated path having an L-shaped cross section, it takes time for the outside air to pass through the ventilation room 7 and reach the attic space 3 In other words, ambient air does not flow into the attic space 3 all at once through the air passage before the air passage is completely blocked by the heated foams 8 and 8 that expand upon receiving the high temperature outside air. In addition, since the horizontal partition surface portion 63 of the partition member 6 is positioned above the heating foam material 8 attached in the vicinity of the ventilation hole 53 and the air passage of the outside air above the heating foam material 8 is narrowed, It can be expanded in a short time in response to the heated external air entering from the pores 53, and the air holes 53 can be closed efficiently and in a short time.
