図4は、図1で示した雨押え構造体を屋根部施工前の取り合い部分に取り付ける取付方法を示す側面模式図である。 FIG. 4 is a schematic side view showing a mounting method for mounting the flashing structure shown in FIG. 1 to the connecting portion before construction of the roof.

まず、図4の(1)を参照して、桁行方向(図の奥行き方向)の取り合い部分90において、垂直に延びる母屋の外壁部75には外壁下地76が、下屋の屋根部81には外壁部75の途中から外方に向かって下方に傾斜するように延びる野地板82が、それぞれ設置されており、外壁下地76の外方側の面及び野地板82の上面に渡って防水紙80が布設されている。 First, referring to FIG. 4(1), at a connecting portion 90 in the girder direction (the depth direction in the drawing), an outer wall foundation 76 is provided on the outer wall portion 75 of the main building extending vertically, and an outer wall base 76 is provided on the roof portion 81 of the lower building. A sheathing board 82 extending outward from the middle of the outer wall part 75 so as to incline downward is installed, and the waterproof paper 80 extends over the outer surface of the outer wall foundation 76 and the upper surface of the sheathing board 82 . is laid.

この状態で、外壁下地近接部11を介して先雨押え10を外壁下地76に取り付けて固定する。次いで外壁下地近接部11の外面上方を覆うように透湿防水シート77を外壁下地76及び外壁下地近接部11に貼着し、透湿防水シート77の外方側の面に上下方向に延びる棒状の胴縁78を桁行方向に所定間隔で複数本設置し、胴縁78の各々を架け渡すように、板状の外壁材79を胴縁78の外方側の面から設置する。 In this state, the front rain flashing 10 is attached and fixed to the outer wall base 76 via the outer wall base neighboring portion 11.例文帳に追加Next, a moisture-permeable waterproof sheet 77 is attached to the outer wall substrate 76 and the outer wall substrate-proximate portion 11 so as to cover the upper outer surface of the outer wall substrate adjacent portion 11, and a rod-shaped sheet extending vertically extends on the outer surface of the moisture-permeable waterproof sheet 77. A plurality of furring strips 78 are installed at predetermined intervals in the girder direction, and a plate-shaped outer wall material 79 is installed from the outer surface of the furring strips 78 so as to span each of the furring strips 78 .

このようにして、図4の(2)に示すように、外壁部75側への先雨押え10の施工及び外壁材79までの施工を完了する。 In this way, as shown in FIG. 4B, the installation of the rain flashing 10 on the outer wall portion 75 side and the installation up to the outer wall material 79 are completed.

次に、図4の(2)を参照して、施工が完了した先雨押え10の下方の範囲を含めて、屋根材83を屋根部81の防水紙80の上に設置する。 Next, referring to FIG. 4(2), a roof material 83 is installed on the waterproof paper 80 of the roof section 81, including the area below the pre-construction flashing 10. As shown in FIG.

次に、図4の(3)を参照して、屋根材83の外壁下地76の側の端部に更に笠木84を設置した後、後雨押え20を、笠木84の外方側から外壁部75の側に向けてスライドさせて、後雨押え20の第2折曲部24を、第1折曲部14と屋根部81(笠木84)との隙間に押し込む。すると、先雨押え10及び後雨押え20の構成は上述した通りであるから、第2折曲部24が押し込まれることにより第1連結部12が撓んで上方に押し上げられる。その状態から更に押し込みを進めて第2折曲部24が第1折曲部14よりも外壁部75の側に位置すると、第2折曲部24が第1折曲部14から離れ、第1連結部12には押し上げられる力がかからなくなり、第1連結部12が元の位置に戻る。すると、上述したように第2折曲部24は上方側に、第1折曲部14は下方側に、それぞれ折り返すハゼ構造を有しているから、図4の(4)及び図1の(1)に示すように、第2折曲部24と第1折曲部14とが掛け合って連結する。このように第2連結部22は、先雨押え10及び外壁部75の施工をした後の後雨押え20の施工時に、第1連結部12に連結可能なものとなっている。 Next, referring to (3) of FIG. 4, after further installing a headboard 84 at the end of the roof material 83 on the outer wall foundation 76 side, the rear flashing 20 is attached from the outer side of the headboard 84 to the outer wall section. By sliding it toward the side of 75, the second bent portion 24 of the rear flashing 20 is pushed into the gap between the first bent portion 14 and the roof portion 81 (coping 84). Then, since the structures of the front flashing 10 and the rear flashing 20 are as described above, the pushing of the second bent portion 24 bends the first connecting portion 12 and pushes it upward. When the second bent portion 24 is positioned closer to the outer wall portion 75 than the first bent portion 14, the second bent portion 24 separates from the first bent portion 14 and the first The connecting part 12 is no longer pushed up, and the first connecting part 12 returns to its original position. Then, as described above, the second bent portion 24 and the first bent portion 14 have seam structures that are bent upward and downward, respectively. 1), the second bent portion 24 and the first bent portion 14 are hooked and connected. In this manner, the second connecting portion 22 can be connected to the first connecting portion 12 when the rear flashing 20 is constructed after the front flashing 10 and the outer wall portion 75 have been constructed.

最後に、図4の(4)を参照して、屋根部近接部21の垂下部26と笠木84とを介して後雨押え20を屋根部81に固定して、取り合い部分90への雨押え構造体1の取り付けが完了する。 Finally, referring to (4) of FIG. 4, the rear rain flashing 20 is fixed to the roof portion 81 via the drooping portion 26 of the roof portion neighboring portion 21 and the coping 84, and the rain flashing to the interface portion 90 is fixed. Installation of the structure 1 is completed.

このように構成すると、外壁部75側の施工後に屋根部81側の施工ができるので、施工効率が向上する。 With this configuration, construction on the roof portion 81 side can be performed after construction on the outer wall portion 75 side, thereby improving construction efficiency.

又、連結構造がハゼ構造による簡易なものとなるので、コスト的に有利となる。 Moreover, since the connecting structure is simple due to the seam structure, it is advantageous in terms of cost.

更に、第1連結部12を撓ませられると共に、各々の内角が30°に設定されている第1折曲部14及び第2折曲部24の係合部分には遊びが生じるので、第1連結部12及び第2連結部22の傾斜角度の調整が可能となり、様々な勾配の屋根に対応可能となる。 Furthermore, when the first connecting portion 12 is flexed, there is play in the engaging portions of the first bent portion 14 and the second bent portion 24, each of which has an internal angle of 30°. It is possible to adjust the inclination angles of the connecting part 12 and the second connecting part 22, and it is possible to deal with roofs with various slopes.

尚、上述したように野地板82には開口85が形成されており、屋内と屋外とは開口85を介して連通している。又、後雨押え40の構成も上述の通りであって、換気口48及び通気孔52(換気材53)を通じて内外に通気可能なものである。したがって、雨押え構造体2が設置された取り合い部分90においては、屋外に面する換気口48から屋内に面する開口85まで連通する通気路57が形成される。換気口48を介して後雨押え40の内部に入り込んだ雨水は、捨水切59により開口85への侵入が阻まれる。 In addition, as described above, the opening 85 is formed in the sheathing board 82, and the interior and the exterior are communicated through the opening 85. As shown in FIG. Also, the rear rain guard 40 is constructed as described above, and is capable of ventilating inside and outside through the ventilation opening 48 and the ventilation hole 52 (ventilation material 53). Therefore, in the joint portion 90 where the flashing structure 2 is installed, a ventilation path 57 is formed that communicates from the ventilation opening 48 facing the outdoors to the opening 85 facing the indoors. Rainwater entering the rear flashing 40 through the ventilation port 48 is prevented from entering the opening 85 by the drainage drain 59. - 特許庁

このように構成すると、後雨押え40が換気機能を備えるので、換気の観点においても良好なものとなる。 With this configuration, the rear rain flashing 40 has a ventilation function, so it is favorable from the viewpoint of ventilation.
