Description

本発明は、下屋の屋根と外壁との間の止水構造に関する。   The present invention relates to a water stop structure between a roof of a lower house and an outer wall.

下屋の屋根と外壁との間の止水のため、外壁面材の背面側に沿って立ち上がる部分と下屋の屋根に沿う部分とを有する止水板を用い、この止水板で下屋の屋根と外壁との境界部を止水する構造では、これまで、止水板の下屋の屋根に沿う部分を、ルーフィングよりも上であって屋根仕上げ材よりも下の位置に設置することが行われていた。   In order to stop the water between the roof and the outer wall of the lower house, a water stopping board having a part rising along the back side of the outer wall material and a part along the roof of the lower house is used. In the structure that stops the boundary between the roof and the outer wall of the building, the part along the roof of the roof of the waterproof plate has been installed above the roofing and below the roof finish. Was done.

しかしながら、上記のように、止水板の下屋の屋根に沿う部分をルーフィングよりも上であって屋根仕上げ材よりも下の位置に設置すれば、確かに、ルーフィングによって防水が確保されているので、下屋屋根に防水上の問題は一応ないといえるが、その一方で、屋根において、ルーフィングはあくまでも二次的な防水手段であり、この二次防水手段に、下屋の屋根と外壁との間の止水のための一次防水機能を担わせるのは、過度の負担を強いることもあり、下屋屋根の防水計画上、妥当の設計とは言い難がたい場合がある。   However, as described above, if the part along the roof of the roof of the waterproofing plate is located above the roofing and below the roof finishing material, the waterproofing is surely secured by the roofing. Therefore, it can be said that there is no problem with waterproofing for the roof of the lower house, but on the other hand, the roofing is only a secondary waterproofing means on the roof. It may be difficult to say that it is a reasonable design in terms of waterproofing plans for the roof of the roof, because it may impose an excessive burden to provide the primary waterproofing function for the water stoppage during the period.

また、上記のように、止水板の下屋の屋根に沿う部分をルーフィングよりも上であって屋根仕上げ材よりも下の位置に設置する構造では、事後的に止水板のメンテナンス等を行う場合に、屋根仕上げ材の取外しが必要となってしまうという問題もある。   In addition, as described above, in the structure where the part along the roof of the bottom of the waterproof plate is installed above the roofing and below the roof finishing material, the maintenance of the waterproof plate is performed afterwards. When performing, there also exists a problem that the removal of a roof finishing material will be needed.

本発明は、上記のような問題点に鑑み、下屋の屋根と外壁との間を止水でき、それでいて、下屋屋根のルーフィングの負担を軽くすることができ、しかも、事後的なメンテナンス等を下屋の屋根仕上げ材を取り外さずに行うことができる、下屋の屋根と外壁との間の止水構造を提供することを課題とする。   In view of the above problems, the present invention can stop water between the roof of the lower roof and the outer wall, yet reduce the burden of roofing of the lower roof, and subsequent maintenance, etc. It is an object of the present invention to provide a water stop structure between the roof of the lower house and the outer wall, which can be performed without removing the roof finishing material of the lower house.

上記の課題は、下屋の屋根と外壁との境界部が、外壁面材よりも背後を立ち上がる部分と下屋の屋根に沿う部分とを有する止水板で止水された、下屋の屋根と外壁との間の止水構造であって、
前記止水板の下屋の屋根に沿う部分が、下屋の屋根の屋根仕上げ材の上面側に設置されていることを特徴とする下屋の屋根と外壁との間の止水構造によって解決される。 The above problem is that the boundary between the roof of the lower house and the outer wall is stopped by a water stop plate having a part that stands behind the outer wall material and a part that extends along the roof of the lower house. A waterproof structure between the outer wall and the outer wall,
The part along the roof of the lower roof of the water stop plate is installed on the upper surface side of the roof finishing material of the roof of the lower roof. Is done.

この構造では、止水板の下屋の屋根に沿う部分が下屋の屋根の屋根仕上げ材の上面側に設置されているので、止水板で止水された水は、下屋の屋根の側に流れ去ることができて、下屋の屋根と外壁との間をしっかりと止水することができ、それでいて、下屋の屋根では、止水板によって止水された水の一次防水を屋根仕上げ材が行うことで、下屋屋根における二次防水手段であるルーフィングへの防水上の負担を軽くすることができる。   In this structure, the part along the roof of the lower roof is installed on the upper surface side of the roof finishing material of the lower roof. It can flow to the side and can firmly stop water between the roof of the lower house and the outer wall, yet the roof of the lower house has the primary waterproofing of the water stopped by the water stop plate. By performing the finishing material, it is possible to lighten the burden on waterproofing to the roofing which is the secondary waterproofing means in the lower roof.

しかも、上記のように、止水板の下屋の屋根に沿う部分が下屋の屋根の屋根仕上げ材の上面側に設置されることで、止水板に対して行われる事後的なメンテナンス等を下屋の屋根仕上げ材を取り外さずに行うことができる。   In addition, as described above, the part along the roof of the roof of the waterproof plate is installed on the upper surface side of the roof finishing material of the roof of the roof, so that subsequent maintenance performed on the waterproof plate, etc. Can be done without removing the roof finish of the lower house.

本発明は、以上のとおりのものであるから、下屋の屋根と外壁との間を止水でき、それでいて、下屋屋根の二次防水手段であるルーフィングの負担を軽くすることができ、しかも、事後的なメンテナンス等を下屋の屋根仕上げ材を取り外さずに行うことができる。   Since the present invention is as described above, it is possible to stop water between the roof of the lower roof and the outer wall, and to reduce the burden of roofing, which is a secondary waterproofing means for the lower roof, Subsequent maintenance can be performed without removing the roof finishing material of the lower house.

次に、本発明の実施最良形態を図面に基づいて説明する。   Next, the best mode for carrying out the present invention will be described with reference to the drawings.

図１〜図３に示す実施形態の止水構造において、１は建物の外壁、２は建物に付属する下屋の屋根、３はそれらの境界部を止水する止水板である。   1 to 3, 1 is an outer wall of a building, 2 is a roof of a lower house attached to the building, and 3 is a water stopping plate that stops water at the boundary portion thereof.

外壁１は、窯業系などの外壁面材１ａの背面側に、木や発砲ポリスチレンなどからなる下地材１ｂを介して、鋼製のパネルフレーム１ｃが備えられた外壁パネルで構成されており、外壁面材１ａの下縁部の背面側に備えられている下地材１ｂの背面側には切欠き４が形成され、この切欠き４によって、下地材１ｂとパネルフレーム１ｃとの間に、下方に開放された止水板差込み部５が備えられている。なお、６は胴差である。   The outer wall 1 is composed of an outer wall panel in which a steel panel frame 1c is provided on a back side of an outer wall material 1a such as a ceramic industry through a base material 1b made of wood, foamed polystyrene, or the like.
