Description

本発明は、開口部周りの鎧張り構造に関する。より詳細には、本発明は、開口部周りに建築板を鎧張りした構造に関する。 The present invention relates to a clinker structure around an opening. More specifically, the present invention relates to a structure in which a building board is armed around an opening.

特許文献1には、開口部の周囲における鎧下見張りの外壁の葺き構造が記載されている。この構造では、外壁下地の開口部の両側に設けられた開口縦枠の側縁に防水パッキンを貼着している。防水パッキンの表面にはくさび状部が複数段に形成されている。外壁材は、その上面をくさび状部の下面に当接すると共に、裏面をくさび状部の傾斜面に当接するようにしている。このような構造では、外壁材の裏面と外壁下地との間に防水パッキンが充填されているため、雨水が外壁材の裏面を伝って外壁下地に達するのを防水パッキンで防止することができ、防水性を得ることができる。 Patent Document 1 describes the roofing structure of the outer wall of the armor lookout around the opening. In this structure, waterproof packing is attached to the side edges of the vertical opening frame provided on both sides of the opening under the outer wall. A wedge-shaped portion is formed in a plurality of stages on the surface of the waterproof packing. The upper surface of the outer wall material is in contact with the lower surface of the wedge-shaped portion, and the back surface is in contact with the inclined surface of the wedge-shaped portion. In such a structure, since the waterproof packing is filled between the back surface of the outer wall material and the outer wall base, the waterproof packing can prevent rainwater from traveling along the back surface of the outer wall material and reaching the outer wall base. Waterproofness can be obtained.

しかし、特許文献1に記載された構造では、防水パッキンをサッシ枠の全体にキッチリと密着させる必要があり、また防水パッキンを鎧張りの形状に合わせて用意する必要があった。したがって、施工に手間がかかることがあった。また、板の切断面にカケがあると、その部分から水が入ることがあり、防水性が低下する場合があった。 However, in the structure described in Patent Document 1, it is necessary to tightly adhere the waterproof packing to the entire sash frame, and it is necessary to prepare the waterproof packing according to the shape of the armor. Therefore, it may take time and effort for construction. In addition, if there is a chip on the cut surface of the plate, water may enter from that portion, which may reduce the waterproof property.

本発明は、上記事由に鑑みてなされており、施工に手間がかかりにくく、防水性の低下が生じにくい開口部周りの鎧張り構造を提供することを目的とする。 The present invention has been made in view of the above reasons, and an object of the present invention is to provide a clinker structure around an opening, which is less troublesome to construct and less likely to cause a decrease in waterproofness.

本発明の一態様に係る開口部周りの鎧張り構造は、開口枠の側面に止水材を介して見切り縁が取り付けられている。前記見切り縁の開放溝に鎧張り状に配置された建築板の端部が差し込まれている。前記開口枠の角部周りに捨て水切りが設けられている。前記捨て水切りの下部は前記建築板の表面上に配置されている。 In the clinker structure around the opening according to one aspect of the present invention, a parting edge is attached to the side surface of the opening frame via a water blocking material. The end of the building board arranged in a clinker shape is inserted into the open groove of the parting edge. A drainer is provided around the corner of the opening frame. The lower part of the drainer is arranged on the surface of the building board.

本発明によれば、雨水は建築板の表面から見切り縁の開放溝に導入することができ、開口枠に雨水が達しにくくすることができ、また雨水は開口枠の角部周りから捨て水切りの表面を流れて建築板の表面へと排水することができ、開口部周りの防水性を向上することができる、という利点がある。さらに止水材は鎧張りの形状に合わせて加工されなくてもよく、施工に手間がかかりにくい、という利点がある。 According to the present invention, rainwater can be introduced from the surface of the building board into the open groove of the parting edge, making it difficult for rainwater to reach the opening frame, and rainwater is drained from around the corners of the opening frame. It has the advantage that it can flow through the surface and drain to the surface of the building board, improving the waterproofness around the opening. Furthermore, the water blocking material does not have to be processed according to the shape of the armor, and has the advantage that it does not take much time and effort to construct.

本実施形態に係る開口部周りの鎧張り構造は、下地7に形成された開口部8の周囲に建築板4を鎧張り状に配置した構造を有している(図1A及び図1B参照)。下地7は壁下地であって、下地7の外面に複数枚の建築板4が配置されている。なお、本実施形態は、建物の外壁における開口部周りの鎧張り構造を説明する。この場合、「室外側」とは、建物の外部(屋外)のことを意味し、「室内側」とは、建物の内部(屋内)のことを意味する。
(Embodiment)
The clinker structure around the opening according to the present embodiment has a structure in which the building board 4 is arranged in a clinker shape around the opening 8 formed in the base 7 (see FIGS. 1A and 1B). .. The base 7 is a wall base, and a plurality of building boards 4 are arranged on the outer surface of the base 7. In this embodiment, the clinker structure around the opening in the outer wall of the building will be described. In this case, the "outdoor side" means the outside (outdoor) of the building, and the "indoor side" means the inside (indoor) of the building.

下地7は、まぐさ70、窓台71及び間柱72を有している。まぐさ70及び窓台71は一対の間柱72の間に架け渡して取り付けられている。また下地7は、補助胴縁73を有している。補助胴縁73は、まぐさ70、窓台71及び間柱72の各々の室外側面に設けられている。また下地7は、縦胴縁74を有している。縦胴縁74は、まぐさ70の室外側面に設けた補助胴縁73の上方と、窓台71の室外側面に設けた補助胴縁73の下方とに各々設けられている。さらに下地7は、下地板75を有している。下地板75は合板や石膏ボードなどの板材で構成されている。下地板75は補助胴縁73及び縦胴縁74の室外側面に設けられている。そして、下地7は開口部8を有している。開口部8は、下地板75の室外側から間柱72、まぐさ70及び窓台71の室内側にまで至るように形成されている。開口部8は、正面視(室外側から見た場合)で四角形に形成されている。 The base 7 has a lintel 70, a window sill 71, and a stud 72. The lintel 70 and the window sill 71 are attached so as to be bridged between a pair of studs 72. Further, the base 7 has an auxiliary furring strip 73. Auxiliary furring strips 73 are provided on the outdoor surfaces of the lintel 70, the window sill 71, and the studs 72. Further, the base 7 has a vertical furring strip 74. The vertical furring strip 74 is provided above the auxiliary furring strip 73 provided on the outdoor surface of the lintel 70 and below the auxiliary furring strip 73 provided on the outdoor side surface of the window sill 71, respectively. Further, the base 7 has a base plate 75. The base plate 75 is made of a plate material such as plywood or gypsum board. The base plate 75 is provided on the outdoor side surface of the auxiliary furring strip 73 and the vertical furring strip 74. The base 7 has an opening 8. The opening 8 is formed so as to extend from the outdoor side of the base plate 75 to the indoor side of the stud 72, the lintel 70, and the window sill 71. The opening 8 is formed in a quadrangular shape when viewed from the front (when viewed from the outdoor side).

下地7には開口枠1が取り付けられている。開口枠1はアルミニウムなどの金属製の枠体を使用することができる。開口枠1は、例えば、サッシ枠などを用いた窓枠で構成することができる。開口枠1の内側には窓板を設けると窓を形成することができる。また開口枠1としてレール部材を使用すると、窓板を引き戸として開閉可能な窓を形成することができる。 An opening frame 1 is attached to the base 7. As the opening frame 1, a metal frame such as aluminum can be used. The opening frame 1 can be configured by, for example, a window frame using a sash frame or the like. A window can be formed by providing a window plate inside the opening frame 1. Further, when the rail member is used as the opening frame 1, a window that can be opened and closed can be formed by using the window plate as a sliding door.

開口枠1は開口部8の縁部80に沿って開口部8の全周にわたって設けられている。したがって、開口枠1は正面視で四角形に形成されている。開口枠1は横枠12と縦枠13とを有している。横枠12は横方向に沿って延びるように形成されている。横枠12は開口部8の上の縁部80と、開口部8の下の縁部80との各々にほぼ全長にわたって設けられている。また縦枠13は開口部8の左の縁部80と、右の縁部80との各々にほぼ全長にわたって設けられている。開口枠1の室内側の端部は、まぐさ70と窓台71と一対の間柱72に釘やビスなどで固定されている。また開口枠1の室外側の端部は開口部8の室外側端部よりも外側に突出している。すなわち、開口枠1の室外側の端部は、下地板75の室外側面よりも室外側(前方)に位置している。 The opening frame 1 is provided along the edge 80 of the opening 8 over the entire circumference of the opening 8. Therefore, the opening frame 1 is formed in a quadrangular shape when viewed from the front. The opening frame 1 has a horizontal frame 12 and a vertical frame 13. The horizontal frame 12 is formed so as to extend along the lateral direction. The horizontal frame 12 is provided at each of the upper edge portion 80 of the opening 8 and the lower edge portion 80 of the opening 8 over a substantially overall length. Further, the vertical frame 13 is provided at each of the left edge portion 80 and the right edge portion 80 of the opening 8 over substantially the entire length. The indoor end of the opening frame 1 is fixed to the lintel 70, the window sill 71, and a pair of studs 72 with nails, screws, or the like. Further, the outdoor end of the opening frame 1 projects outward from the outdoor end of the opening 8. That is, the outdoor end of the opening frame 1 is located on the outdoor side (front) of the outdoor surface of the base plate 75.

開口枠1には、止水材2を介して見切り縁3が取り付けられている。見切り縁3はアルミニウムなどの金属製の部材である。図2Aに示すように、見切り縁3は横断面形状が略コの字形状をなし、開放溝30を有している。また見切り縁3は、固定部31と被覆部32とを有している。固定部31と被覆部32は対向しており、固定部31と被覆部32との間の空間が開放溝30として形成されている。固定部31と被覆部32との一端は連結部34により連結されている。この連結部3は、横断面がクランク形状をなし、連結部34の外面(開放溝30と反対側の面)に止水材2が設けられている。止水材2は防水シーラーであって、ゴムやエラストマーなどの弾性を有する材料で形成されている。図2Bは、開口枠1の上面14に設けられる上用の見切り縁3aであり(図1B参照)、見切り縁3aには被覆部32に排水用の孔33が設けられている。図2Cは、開口枠1の側面10及び下面15に設けられる左右下用の見切り縁3bであり(図1A及び図1B参照)、見切り縁3bには排水用の孔33が設けられていない。また、開放溝30の固定部31側の内面には、位置決め片35が突出形成されており、この位置決め片35に、開放溝30に差し込まれた建築板4の端面が当たって位置決めされる。 A parting edge 3 is attached to the opening frame 1 via a water blocking material 2. The parting edge 3 is a metal member such as aluminum. As shown in FIG. 2A, the parting edge 3 has a substantially U-shaped cross section and has an open groove 30. Further, the parting edge 3 has a fixing portion 31 and a covering portion 32. The fixed portion 31 and the covering portion 32 face each other, and a space between the fixing portion 31 and the covering portion 32 is formed as an open groove 30. One end of the fixing portion 31 and the covering portion 32 is connected by the connecting portion 34. The connecting portion 3 has a crank shape in cross section, and a water blocking material 2 is provided on the outer surface (the surface opposite to the opening groove 30) of the connecting portion 34. The waterproof material 2 is a waterproof sealer, and is made of an elastic material such as rubber or an elastomer. FIG. 2B is an upper parting edge 3a provided on the upper surface 14 of the opening frame 1 (see FIG. 1B), and the parting edge 3a is provided with a drainage hole 33 in the covering portion 32. FIG. 2C shows the left and right lower parting edges 3b provided on the side surface 10 and the lower surface 15 of the opening frame 1 (see FIGS. 1A and 1B), and the parting edge 3b is not provided with a drainage hole 33. Further, a positioning piece 35 is formed so as to project on the inner surface of the opening groove 30 on the fixing portion 31 side, and the end surface of the building plate 4 inserted into the opening groove 30 is in contact with the positioning piece 35 for positioning.

見切り縁3は開口枠1の外周面に沿って設けられている。見切り縁3は、開口部8よりも室外側に配置されている。すなわち、見切り縁3は、開口部8よりも室外側に突出する開口枠1の室外側端部に沿って設けられている。見切り縁3は、開口部8の縁部80において、下地7の室外側面に固定されている。この場合、見切り縁3の固定部31が下地板75の表面に両面防水テープなどの固定部材で固定されている。 The parting edge 3 is provided along the outer peripheral surface of the opening frame 1. The parting edge 3 is arranged on the outdoor side of the opening 8. That is, the parting edge 3 is provided along the outdoor end of the opening frame 1 that projects outward from the opening 8. The parting edge 3 is fixed to the outdoor surface of the base 7 at the edge 80 of the opening 8. In this case, the fixing portion 31 of the parting edge 3 is fixed to the surface of the base plate 75 with a fixing member such as a double-sided waterproof tape.

開口枠1の横方向の側面10には見切り縁3が設けられている。この場合、見切り縁3は縦方向に延びるように設けられている。また止水材2は側面10に密着して配置される。したがって、開放溝30は開口部8とは反対側に向いて開放されることになる。また開口枠1の上面14にも見切り縁3が設けられている。この場合、見切り縁3は横方向に延びるように設けられている。また止水材2は上面14に密着して配置される。したがって、開放溝30は開口部8とは反対側(上方)に向いて開放されることになる。また開口枠1の下面15にも見切り縁3が設けられている。この場合、見切り縁3は横方向に延びるように設けられている。また止水材2は下面15に密着して配置される。したがって、開放溝30は開口部8とは反対側(下方)に向いて開放されることになる。 A parting edge 3 is provided on the lateral side surface 10 of the opening frame 1. In this case, the parting edge 3 is provided so as to extend in the vertical direction. Further, the water blocking material 2 is arranged in close contact with the side surface 10. Therefore, the opening groove 30 is opened toward the side opposite to the opening 8. A parting edge 3 is also provided on the upper surface 14 of the opening frame 1. In this case, the parting edge 3 is provided so as to extend in the lateral direction. Further, the water blocking material 2 is arranged in close contact with the upper surface 14. Therefore, the opening groove 30 is opened toward the opposite side (upper side) of the opening 8. A parting edge 3 is also provided on the lower surface 15 of the opening frame 1. In this case, the parting edge 3 is provided so as to extend in the lateral direction. Further, the water blocking material 2 is arranged in close contact with the lower surface 15. Therefore, the opening groove 30 is opened toward the opposite side (downward) of the opening 8.

このように開口枠1に止水材2を密着させた状態で見切り縁3を配置することにより、開口枠1と見切り縁3の連結部34との間から雨水が室内側へと浸入しにくくなり、開口部8の周囲の防水性を向上させることができる。 By arranging the parting edge 3 with the waterproof material 2 in close contact with the opening frame 1 in this way, it is difficult for rainwater to enter the indoor side from between the opening frame 1 and the connecting portion 34 of the parting edge 3. Therefore, the waterproof property around the opening 8 can be improved.

開口枠1の周囲には複数の建築板4が取り付けられている。各建築板4は釘やビスなどの固定具で下地7に固定されている。建築板4は下地板75の室外側面に沿って縦横に並べて配置されている。複数の建築板4は鎧張り状に配置されている。すなわち、縦方向で隣接する建築板4において、上側の建築板4の下部が下側の建築板4の上部の表面上に位置するようにして配置されている。つまり、縦方向で隣接する建築板4の上部と下部とが重なった状態で施工されている。 A plurality of building boards 4 are attached around the opening frame 1. Each building board 4 is fixed to the base 7 with a fixture such as a nail or a screw. The building boards 4 are arranged vertically and horizontally along the outdoor side surface of the base board 75. The plurality of building boards 4 are arranged in a clinker shape. That is, in the vertically adjacent building boards 4, the lower part of the upper building board 4 is arranged so as to be located on the upper surface of the lower building board 4. That is, the construction is carried out in a state where the upper portion and the lower portion of the vertically adjacent building boards 4 overlap.

建築板4の端部40は見切り縁3の開放溝30に差し込まれている。すなわち、開口枠1の上方に位置する建築板4の端部(下端部)40は、開口枠1の上に設けた見切り縁3の開放溝30に上方から差し込まれている。また開口枠1の下方に位置する建築板4の端部(上端部)40は、開口枠1の下に設けた見切り縁3の開放溝30に下方から差し込まれている。また開口枠1の側方に位置する建築板4の端部(側端部)40は開口枠1の横に設けた見切り縁3の開放溝30に側方から差し込まれる。 The end 40 of the building board 4 is inserted into the open groove 30 of the parting edge 3. That is, the end portion (lower end portion) 40 of the building board 4 located above the opening frame 1 is inserted from above into the opening groove 30 of the parting edge 3 provided on the opening frame 1. Further, the end portion (upper end portion) 40 of the building board 4 located below the opening frame 1 is inserted from below into the opening groove 30 of the parting edge 3 provided under the opening frame 1. Further, the end portion (side end portion) 40 of the building board 4 located on the side of the opening frame 1 is inserted from the side into the opening groove 30 of the parting edge 3 provided on the side of the opening frame 1.

このように、建築板4の端部40を開放溝30に差し込むことにより、端部40が被覆部32で隠されて室外側から見えにくくなる。したがって、建築板4が長さ調整のために切断された場合に、端部40に欠けが生じている場合であっても、この欠けが被覆部32で見えにくくなって、壁の外観が損なわれにくい。また建築板4の表面を流れる雨水が開放溝30に導入されて開放溝30内を流れて排水されることになり、開口枠1に雨水が到達しにくくなって、開口部8の周囲の防水性を向上させることができる。 By inserting the end portion 40 of the building board 4 into the open groove 30 in this way, the end portion 40 is hidden by the covering portion 32 and becomes difficult to see from the outdoor side. Therefore, when the building board 4 is cut for length adjustment, even if the end portion 40 is chipped, the chipped portion becomes difficult to see in the covering portion 32, and the appearance of the wall is impaired. It is hard to get rid of. Further, rainwater flowing on the surface of the building board 4 is introduced into the opening groove 30 and flows through the opening groove 30 to be drained, which makes it difficult for rainwater to reach the opening frame 1 and waterproofs the periphery of the opening 8. The sex can be improved.

本実施形態では、さらに、捨て水切り5を備えている。捨て水切り5は、開口部8の周囲の防水性を向上させるための部材である。捨て水切り5は正面視で四角形の開口枠1の四つの角部11に対応する位置に各々設けられている。図3A〜図3Dに示すように、捨て水切り5は本体部51と止水部52とを有している。本体部51はステンレス鋼板などの金属板で形成されている。本体部51は縦方向に延びるように形成されており、本体部51の側端部には縦方向に沿って延びる水返し部53が設けられている。また本体部51には開口枠1の角部11が配置される切欠部54が設けられている。この切欠部54周り(捨て水切り5の一部)が見切り縁3の裏側に位置する。水返し部53は本体部51の表面に突出するように形成されている。止水部52は本体部51の表面において水返し部53に沿って設けられている。止水部52は防水シーラーであって、ゴムやエラストマーなどの弾性を有する材料で形成されている。図3Aに示す捨て水切り5aは、開口枠1の左上の角部11に対応する位置に配置される。図3Bに示す捨て水切り5bは、開口枠1の右上の角部11に対応する位置に配置され、左上用の捨て水切り5aに対して左右対称形状を有している。図3Cに示す捨て水切り5cは、開口枠1の左下の角部11に対応する位置に配置される。図3Dに示す捨て水切り5dは、開口枠1の右下の角部11に対応する位置に配置され、左下用の水切り5cに対して左右対称形状を有している。 The present embodiment further includes a drainer 5. The drainer 5 is a member for improving the waterproof property around the opening 8. The drainer 5 is provided at a position corresponding to the four corners 11 of the quadrangular opening frame 1 when viewed from the front. As shown in FIGS. 3A to 3D, the drainer 5 has a main body 51 and a water stop 52. The main body 51 is formed of a metal plate such as a stainless steel plate. The main body 51 is formed so as to extend in the vertical direction, and a water return portion 53 extending in the vertical direction is provided at a side end portion of the main body 51. Further, the main body 51 is provided with a notch 54 in which the corner 11 of the opening frame 1 is arranged. The circumference of the notch 54 (a part of the drainer 5) is located on the back side of the parting edge 3. The water return portion 53 is formed so as to project from the surface of the main body portion 51. The water stop portion 52 is provided on the surface of the main body portion 51 along the water return portion 53. The water stop portion 52 is a waterproof sealer and is made of an elastic material such as rubber or elastomer. The drainer 5a shown in FIG. 3A is arranged at a position corresponding to the upper left corner 11 of the opening frame 1. The drainer 5b shown in FIG. 3B is arranged at a position corresponding to the upper right corner 11 of the opening frame 1 and has a symmetrical shape with respect to the drainer 5a for the upper left. The drainer 5c shown in FIG. 3C is arranged at a position corresponding to the lower left corner portion 11 of the opening frame 1. The drainer 5d shown in FIG. 3D is arranged at a position corresponding to the lower right corner 11 of the opening frame 1 and has a symmetrical shape with respect to the lower left drainer 5c.

本実施形態を施工するにあたっては、まず、図4Aに示すように、開口部8に開口枠1を設けた下地7に対して、建築板4を取り付けていく。横方向に隣接する建築板4は突付けて配置される。また横方向に一列に並ぶ建築板4を一段とし、下から上に向かって一段ずつ建築板4を取り付けていく。建築板4は開口枠1に達する段よりも一段下にまで取り付ける。なお、「左」とは、正面視(建物の外壁を室外側から見た場合)において、横方向の一方側を意味し、「右」とは、正面視において、横方向の他方側(左と反対側)を意味する。「上」とは鉛直上方向を意味し、「下」とは鉛直下方向を意味する。上下方向は縦方向と同義である。 In constructing the present embodiment, first, as shown in FIG. 4A, the building board 4 is attached to the base 7 provided with the opening frame 1 in the opening 8. The building boards 4 adjacent to each other in the lateral direction are arranged so as to abut each other. Further, the building boards 4 arranged in a row in the horizontal direction are set as one step, and the building boards 4 are attached one step at a time from the bottom to the top. The building board 4 is attached one step below the step reaching the opening frame 1. In addition, "left" means one side in the lateral direction in the front view (when the outer wall of the building is viewed from the outdoor side), and "right" means the other side in the lateral direction (left) in the front view. On the other side). "Up" means vertically upward, and "down" means vertically downward. The vertical direction is synonymous with the vertical direction.

次に、図4Bに示すように、開口枠1の下部の左右両側の角部11の周囲において、捨て水切り5を配置する。ここでは、捨て水切り5は左下用の捨て水切り5cと右下用の捨て水切り5dが使用される。捨て水切り5は切欠部54を開口枠1の角部11に位置させ、開口枠1の外周面に沿わせるように配置する。また捨て水切り5は上部(正面視において上側略半分の部分)が下地7に固定される。この場合、捨て水切り5に釘穴やビス穴が形成されないように、粘着テープなどで捨て水切り5の裏面を下地7の下地板75の室外側面に固定する。また捨て水切り5は下部(正面視において下側略半分の部分)が建築板4の表面上(室外側面上)に配置される。この場合、捨て水切り5の下部は捨て水切り5の上端よりも下側に位置する建築板4の表面上に配置される。また捨て水切り5の下部は下段の建築板4の表面上に配置される。すなわち、縦方向で隣接する建築板4のうちの下側の建築板4の表面上に配置される。また捨て水切り5は下段の建築板4の上部(正面視において上側略半分の部分)の表面上に配置される。下段の建築板4の上部は上段の建築板4の下部が重なる部分であって、非暴露部42である。捨て水切り5は非暴露部42よりも下方に位置しないように、切断等により長さ調整される。なお、図4B及び図4Cにおいて、建築板4に付した想像線よりも上側の部分が非暴露部42であり、想像線よりも下側の部分が暴露部43である。 Next, as shown in FIG. 4B, the drainer 5 is arranged around the corners 11 on both the left and right sides of the lower portion of the opening frame 1. Here, as the drainer 5, a drainer 5c for the lower left and a drainer 5d for the lower right are used. The drainer 5 is arranged so that the notch 54 is located at the corner 11 of the opening frame 1 and is aligned with the outer peripheral surface of the opening frame 1. Further, the upper part of the drainer 5 (the upper half of the drainer 5 in the front view) is fixed to the base 7. In this case, the back surface of the drainer 5 is fixed to the outdoor surface of the base plate 75 of the base 7 with an adhesive tape or the like so that nail holes and screw holes are not formed in the drainer 5. Further, the lower part of the drainer 5 (a portion substantially half of the lower side in the front view) is arranged on the surface of the building board 4 (on the outdoor side surface). In this case, the lower portion of the drainer 5 is arranged on the surface of the building board 4 located below the upper end of the drainer 5. Further, the lower part of the drainer 5 is arranged on the surface of the lower building board 4. That is, it is arranged on the surface of the lower building board 4 of the vertically adjacent building boards 4. Further, the drainer 5 is arranged on the surface of the upper part (the upper half portion in the front view) of the lower building board 4. The upper part of the lower building board 4 is a portion where the lower part of the upper building board 4 overlaps, and is a non-exposed portion 42. The length of the drainer 5 is adjusted by cutting or the like so as not to be located below the unexposed portion 42. In FIGS. 4B and 4C, the portion above the imaginary line attached to the building board 4 is the unexposed portion 42, and the portion below the imaginary line is the exposed portion 43.

次に、図4Cに示すように、見切り縁3が取り付けられる。ここでは、見切り縁3は左右下用の見切り縁3bが使用され、開口枠1の左右両側の側面10に沿って縦方向に沿って延びるように取り付けられ、また開口枠1の下面15に沿って横方向に延びるように取り付けられる。見切り縁3は、粘着テープを開口枠1の側面10及び下面15に密着させ、止水材2を押しつぶすように押さえながらビス等で下地7に固定する。また開口枠1の左右両側に配置した見切り縁3は、その下端が捨て水切り5(捨て水切り5c及び5d)の表面上に配置される。これにより、見切り縁3の開放溝30を縦方向に流れる雨水が捨て水切り5上に流れることになり、防水性を向上させることができる。また開口枠1の下側に配置した見切り縁3はその左右両端がそれぞれ捨て水切り5の表面上に配置される。これにより、見切り縁3の開放溝30を横方向に流れる雨水(横走)が捨て水切り5上に流れることになり、防水性を向上させることができる。また、捨て水切り5は見切り縁3と開口枠1の角部11周りの下地7との間で挟まれて固定される。 Next, as shown in FIG. 4C, the parting edge 3 is attached. Here, the parting edge 3 for the lower left and right is used as the parting edge 3, and is attached so as to extend in the vertical direction along the side surfaces 10 on both the left and right sides of the opening frame 1, and also along the lower surface 15 of the opening frame 1. It is installed so that it extends laterally. The parting edge 3 is fixed to the base 7 with a screw or the like while the adhesive tape is brought into close contact with the side surface 10 and the lower surface 15 of the opening frame 1 and the water blocking material 2 is pressed so as to be crushed. Further, the lower ends of the parting edges 3 arranged on the left and right sides of the opening frame 1 are arranged on the surface of the drainer 5 (drainer 5c and 5d). As a result, the rainwater flowing in the vertical direction through the open groove 30 of the parting edge 3 is discarded and flows on the drainer 5, and the waterproof property can be improved. Further, the left and right ends of the parting edge 3 arranged on the lower side of the opening frame 1 are arranged on the surface of the drainer 5. As a result, rainwater (horizontal running) flowing laterally through the open groove 30 of the parting edge 3 flows onto the drainer 5, and waterproofness can be improved. Further, the drainer 5 is sandwiched and fixed between the parting edge 3 and the base 7 around the corner portion 11 of the opening frame 1.

次に、図5Aに示すように、開口枠1の角部11の周囲において、シーリングを施す。シーリングは、横枠12と縦枠13とにより構成される開口枠1の角部11と開口部8の縁部80との間の隙間を塞ぐようにして設けられる。また角部11における横枠12と縦枠13との接合部分の隙間を塞ぐようにして設けられる。その他、捨て水切り5の表面と見切り縁3の端部との間の隙間など、防水性を損なうおそれがある隙間をシーリングで塞ぐ。 Next, as shown in FIG. 5A, sealing is performed around the corner portion 11 of the opening frame 1. The sealing is provided so as to close the gap between the corner portion 11 of the opening frame 1 composed of the horizontal frame 12 and the vertical frame 13 and the edge portion 80 of the opening portion 8. Further, it is provided so as to close the gap between the joint portion between the horizontal frame 12 and the vertical frame 13 at the corner portion 11. In addition, the gap between the surface of the drainer 5 and the end of the parting edge 3 and other gaps that may impair waterproofness are closed by sealing.

次に、図5Bに示すように、開口枠1の下方及び側方において、複数の建築板4をさらに下から上に向かって取り付けていく。このとき、開口枠1に隣接して配置される建築板4の端部40は見切り縁3の開放溝30に差し込まれる。開口枠1に隣接して配置される建築板4は長さ調整のため、あるいは開口枠1の形状に合わせるために、切断される場合がある。また図5Cに示すように、開口枠1の側方に隣接している建築板4の上隅部41は開口枠1に近づくに従って下方に傾斜している。すなわち、上隅部41は見切り縁3に向かう方向に下り傾斜している。これにより、建築板4の上隅部41から見切り縁3の開放溝30に向かって雨水が流れやすくなり、排水性を向上させることができる。 Next, as shown in FIG. 5B, a plurality of building boards 4 are further attached from the bottom to the top below and to the side of the opening frame 1. At this time, the end portion 40 of the building board 4 arranged adjacent to the opening frame 1 is inserted into the opening groove 30 of the parting edge 3. The building board 4 arranged adjacent to the opening frame 1 may be cut in order to adjust the length or to match the shape of the opening frame 1. Further, as shown in FIG. 5C, the upper corner 41 of the building board 4 adjacent to the side of the opening frame 1 is inclined downward as it approaches the opening frame 1. That is, the upper corner portion 41 is inclined downward in the direction toward the parting edge 3. As a result, rainwater can easily flow from the upper corner 41 of the building board 4 toward the open groove 30 of the parting edge 3, and the drainage property can be improved.

また捨て水切り5は鎧張り状に配置された建築板4のうちの上側の建築板4により覆われる。すなわち、下段の建築板4の非暴露部42の表面上に配置された捨て水切り5の下部は、上段の建築板4の暴露部43で覆われる。また捨て水切り5の上部は上段の建築板4の非暴露部42の裏側に位置し、この非暴露部42で覆われる。このようにすると、捨て水切り5が室外側から見えにくくなって、外観が損なわれにくくなる。また捨て水切り5の止水部52は建築板4の裏面と密着し、防水性が向上する。 Further, the drainer 5 is covered with the upper building board 4 of the building boards 4 arranged in a clinker shape. That is, the lower portion of the drainer 5 arranged on the surface of the unexposed portion 42 of the lower building board 4 is covered with the exposed portion 43 of the upper building board 4. Further, the upper portion of the drainer 5 is located on the back side of the non-exposed portion 42 of the upper building board 4, and is covered with the non-exposed portion 42. In this way, the drainer 5 is less likely to be seen from the outside of the room, and the appearance is less likely to be impaired. Further, the water stop portion 52 of the drainer 5 is in close contact with the back surface of the building board 4, and the waterproof property is improved.

次に、図6Aに示すように、開口枠1の上部の左右両側の角部11の周囲において、捨て水切り5を配置する。ここでは、捨て水切り5は左上用の捨て水切り5aと右上用の捨て水切り5bが使用される。捨て水切り5は切欠部54を開口枠1の角部11の周辺に位置させ、開口枠1の上面14に沿わせるように配置する。また見切り縁3bの上部の裏側に捨て水切り5の下部が配置される。そして、捨て水切り5は上部が下地7に固定される。この場合、捨て水切り5に釘穴やビス穴が形成されないように、粘着テープなどで捨て水切り5の裏面を下地7の下地板75の室外側面に固定する。また捨て水切り5の下部は、開口枠1の側方において、建築板4の表面上に配置される。この場合、捨て水切り5の下部は捨て水切り5の上端よりも下側に位置する建築板4の表面上に配置される。また捨て水切り5の下部は下段の建築板4の表面上に配置される。すなわち、縦方向で隣接する建築板4のうちの下側の建築板4の表面上に配置される。下段の建築板4の上部は上段の建築板4の下部が重なる部分であって、非暴露部42である。捨て水切り5は非暴露部42よりも下方に位置しないように、切断等により長さ調整される。 Next, as shown in FIG. 6A, the drainer 5 is arranged around the corners 11 on both the left and right sides of the upper part of the opening frame 1. Here, as the drainer 5, the drainer 5a for the upper left and the drainer 5b for the upper right are used. The drainer 5 is arranged so that the cutout portion 54 is located around the corner portion 11 of the opening frame 1 and is aligned with the upper surface 14 of the opening frame 1. Further, the lower part of the drainer 5 is arranged on the back side of the upper part of the parting edge 3b. Then, the upper part of the drainer 5 is fixed to the base 7.
