Description

本発明は、建造物の屋根面に配置される屋根面換気ユニット及び屋根面換気ユニットに用いる下部換気部材に関する。 The present invention relates to a roof ventilation unit disposed on the roof of a building and a lower ventilation member used in the roof ventilation unit.

特許文献１は、屋根の野地板に設けた開口部のまわりに換気路本体等を設置し、換気路本体の外周部を取り囲む捨水切板部材と、換気路本体の上部を覆う上部カバーとを、板金性の一体物とすることで、部品点数の少数化が図られ、施工が容易になり、且つ低コスト化が可能になる換気ユニットを提案している。
しかし、特許文献１による上部カバーは、捨水切板部材の軒側端部から屈曲して軒側に向けて野地板から徐々に離間するように傾斜した傾斜部分と、この傾斜部分の軒側端部から屈曲して野地板と平行に軒側に延設された平坦部分とからなり、傾斜部分に捨水切枠部材を配置している。
従って、特許文献１では、捨水切枠部材の上部空間が傾斜部分によって狭くなっているため換気性能を低下させてしまう。
そこで特許文献２は、捨水切板部材と上部カバーとを板金性の一体物とすることなく止水性を高めるとともに野地開口部の上方空間を確保できる屋根面換気ユニットを提案している。
特許文献２の屋根面換気ユニットによれば、化粧スレートの前端を第１後面板材に当接させることで、化粧スレートの前端と第２後面板材との間に空間を形成するため、化粧スレート前端から侵入する雨水は、化粧スレートの下面に沿って上昇することなく、第１後面板材の下端に落下し、第２後面板材に沿って側方へ流れるため止水性に優れ、また野地開口部の上方空間を確保できるため換気性能が向上する。 Patent Document 1 discloses a method in which a ventilation passage main body, etc. is installed around an opening provided in a sheath board of a roof, and a drain board member surrounding the outer circumference of the ventilation passage main body, and an upper cover that covers the upper part of the ventilation passage main body are installed. , we are proposing a ventilation unit that is made of sheet metal and made into one piece, which reduces the number of parts, facilitates construction, and reduces costs.
However, the upper cover according to Patent Document 1 has a sloped portion that is bent from the eave side end of the drainage board member and is sloped so as to gradually move away from the sheathing board toward the eave side, and an eave side end of this sloped portion. It consists of a flat part that bends from the top and extends parallel to the roofing board toward the eaves, and a drainage cutting frame member is placed on the sloping part.
Therefore, in Patent Document 1, the upper space of the wastewater cutting frame member is narrowed by the sloped portion, which deteriorates the ventilation performance.
Therefore, Patent Document 2 proposes a roof ventilation unit that can improve water-stopping performance and secure space above a field opening without making the drainage board member and the upper cover an integral sheet metal object.
According to the roof ventilation unit of Patent Document 2, by bringing the front end of the decorative slate into contact with the first rear plate material, a space is formed between the front end of the decorative slate and the second rear plate material. Rainwater that enters from the outside does not rise along the bottom surface of the decorative slate, but instead falls to the bottom edge of the first rear panel and flows laterally along the second rear panel, providing excellent water-stopping properties. Ventilation performance improves because the space above can be secured.

特許文献２の屋根面換気ユニットでは、捨水切立ち上げ板にシーリング材を用いる必要が無いにもかかわらず、シーリング材が用いられることがある。
野地開口部の棟側に配置される捨水切立ち上げ板の両側にシーリング材が用いられると、シーリング材の間に雨水が溜まり、溜まった雨水が捨水切立ち上げ板を乗り越え、野地開口部から雨水が浸入してしまうことがある。 In the roof ventilation unit of Patent Document 2, a sealing material is sometimes used on the drainage stand-up board even though it is not necessary to use the sealing material.
When sealing material is used on both sides of the drainage board placed on the ridge side of the field opening, rainwater collects between the sealing materials, goes over the drainage board, and flows out from the field opening. Rainwater may seep in.

そこで本発明は、間違った施工方法によってシーリング材が用いられても防水性能を低下させることがなく、化粧スレートの間から大量の雨水が浸入してもオーバーフローして野地開口部に雨水が浸入することがない屋根面換気ユニット及び屋根面換気ユニットに用いる下部換気部材を提供することを目的とする。 Therefore, the present invention does not reduce the waterproof performance even if the sealant is used with the wrong construction method, and even if a large amount of rainwater infiltrates between the decorative slates, it will overflow and infiltrate the field opening. It is an object of the present invention to provide a roof ventilation unit and a lower ventilation member used for the roof ventilation unit.

また、下部換気水上部材６０は、下部換気水上部材立ち上げ板６２を野地開口部４１の棟側にだけ立ち上げて、野地開口部４１の両側には立ち上げ板を形成しないことで、施工時に下部換気水上部材立ち上げ板６２の両側にシーリング材１０２を用いることがない。 FIG. 5 is an explanatory diagram showing the function and effect of this embodiment. FIG. 5(a) is a perspective view of a main part showing a conventional example, and FIG. 5(b) is a cross-sectional view showing an installed state of a roof ventilation unit according to a conventional example. 5(c) are cross-sectional views showing the installed state of the roof ventilation unit according to this embodiment.
As shown in FIG. 5(a), when a sealing material 102 is used on both sides of the drainage stand-up board 101 placed on the ridge side of the field opening 41, the sealing material shown by the broken line arrow in FIG. 5(a) As shown in FIG. 5(b), the rainwater may accumulate between the openings 102, and as shown in FIG.
On the other hand, as shown in FIG. 5(c), the eave side end 63a of the upper surface plate 63 of the lower ventilation water member is positioned closer to the eave than the lower ventilation water member rising board 72a, and the field opening Since the upper part of the field opening 41 is covered, even if a large amount of rainwater passes between the decorative slates 50 and reaches the lower ventilation water member 60, the rainwater will not enter through the field opening 41.
In addition, the lower ventilation floating member 60 can be constructed by raising the lower ventilation floating member rising board 62 only on the ridge side of the field opening 41 and not forming rising boards on both sides of the field opening 41. Sealing material 102 is not used on both sides of the lower ventilation floating member standing board 62.

It further includes a lower ventilation floating member side mounting plate 65 disposed on the upper surface of the lower ventilation floating member side mounting plate 65 .
In the lower ventilation floating member 60 shown in FIG. 6, there is a possibility that the sealing material 102 is used on both sides of the lower ventilation floating member rising plate 62, but the upper surface plate 63 of the lower ventilation floating member prevents rainwater from entering through the field opening 41. Since the lower ventilation water member 60 has the lower ventilation water member side plate 64, it is possible to more reliably prevent rainwater from entering the field opening 41.

なお本実施例では、天面部材開口部１１を上面板材１２に形成した場合を示したが、天面部材開口部１１を前面板材１３に形成してもよく、天面部材開口部１１を前面板材１３に形成した場合には止水箱２０を天面部材開口部１１に対向させて配置する。 In this embodiment, the case where the top panel member opening 11 is formed in the top plate material 12 is shown, but the top panel member opening 11 may be formed in the front panel material 13, and the top panel member opening 11 is formed in the front panel material 12. When formed on the plate material 13, the water stop box 20 is disposed facing the top member opening 11.
