[作用]
次に、このような構成のボウウインドウ５と建物ユニット２との入隅防水構造の構築方法及びその作用を説明する。
（１）入隅防水構造の構築方法
袖壁本体Ｗを取り付ける前に、建物ユニット２の外壁２ａの袖壁本体Ｗに対向させる外面に入隅水切りシート１９を上下に向けて貼り付ける。この入隅水切りシート１９の上下端は、外壁２ａの上下端まで延設する。そして、ボウウインドウ５を組立ながら、袖壁本体Ｗの端面が外壁２ａに当接するように、袖壁本体Ｗをボウウインドウ５の端に組み付ける。 Such a corner waterproof structure is provided at corners (portions provided with sleeve walls) at both ends of the bow window 5. At this time, the square mass 35 and the vertical rod 36 may be provided on one (right side) hook 28 as shown in FIGS. Accordingly, since the square wall 35 and the vertical rod 36 are not provided on the sleeve wall (not shown) on the left side indicated by the arrow C1 of the bow window 5 in FIGS. 1 and 2, an edge frame (not shown) attached to this portion, It is not necessary to provide the above-mentioned notches 14c and 27a on the exterior panel (not shown), and it is not necessary to provide the above-described notches 14c and insertion holes 33 on the hooks (not shown).
[Action]
Next, a construction method and operation of the corner waterproof structure between the bow window 5 and the building unit 2 having the above-described configuration will be described.
(1) Method for constructing waterproof structure of corner entry Before attaching the sleeve wall body W, the corner corner draining sheet 19 is attached to the outer surface of the outer wall 2a of the building unit 2 facing the sleeve wall body W so as to face up and down. The upper and lower ends of the entrance corner draining sheet 19 extend to the upper and lower ends of the outer wall 2a. Then, while assembling the bow window 5, the sleeve wall body W is assembled to the end of the bow window 5 so that the end surface of the sleeve wall body W comes into contact with the outer wall 2 a.

次に、上支持パネル１５上に防水紙１７を配設し、この防水紙１７の周縁から上方に起立させた起立部１７ａを縁フレーム１４ａ及び仕上材１６の側面に密接（当接）させた後、水平部１７ｂを仕上材１６の上面に密接（当接）させ、屋根床板１８のフランジ１８ａを防水紙１７の起立部１７ａに当接させる。この状態では、袖壁本体Ｗと水切りシート１９との間には、図５〜図８に示したように袖壁本体Ｗの外面（屋根床板１８とは反対側の面）に開放する縦溝２０が形成される。   Next, the waterproof paper 17 is disposed on the upper support panel 15, and the standing portion 17 a that is erected upward from the peripheral edge of the waterproof paper 17 is brought into close contact (contact) with the edge frame 14 a and the side surface of the finishing material 16. Thereafter, the horizontal portion 17 b is brought into close contact (contact) with the upper surface of the finishing material 16, and the flange 18 a of the roof floor board 18 is brought into contact with the standing portion 17 a of the waterproof paper 17. In this state, between the sleeve wall main body W and the draining sheet 19, as shown in FIGS. 5 to 8, a vertical groove opened to the outer surface of the sleeve wall main body W (the surface opposite to the roof floor board 18). 20 is formed.

この縦溝２０内に上下に延びるスポンジチューブをシール材２１として挿入して、このシール材２１を断面Ｗａと外壁２ａに弾接させ、袖壁本体Ｗの段面Ｗａと外壁２ａとの間をシールさせると共に、シール材２１の上端を仕上材１６の上端と一致させる。このシール材２１の周囲に変成シリコン材等を図１１のチューブＣｈから押し出してを充填すると共に、袖壁本体Ｗの外壁２ａへの当接部に変成シリコン材等を塗布して防水する。   A sponge tube extending vertically is inserted into the vertical groove 20 as a sealing material 21, and the sealing material 21 is elastically contacted with the cross-section Wa and the outer wall 2 a, and between the step surface Wa of the sleeve wall body W and the outer wall 2 a. While sealing, the upper end of the sealing material 21 is made to correspond with the upper end of the finishing material 16. The seal material 21 is filled with a modified silicon material or the like extruded from the tube Ch in FIG. 11, and the modified silicon material or the like is applied to the contact portion of the sleeve wall body W with the outer wall 2a to be waterproofed.

この後、シート状防水役物２２の防水シート２３を袖壁本体Ｗに貼り付ける。即ち、シート状防水役物２２の剥離シート２４ａ，２５ａを防水シート２３の粘着層２４，２５から剥離する。そして、剥離シート２４ａ，２５ａが剥離された防水シート２３を、外面側縦シート部２３ａ，横シート部２３ｂ，床板側縦シート部２３ｃが粘着層２４を介して袖壁本体Ｗの外面，仕上材１６の上面及び防水紙１７の水平部１７ｂ，防水紙１７の起立部１７ａにそれぞれ粘着固定する。一方、防水シート２３を、壁取付シート部２３ｄが粘着層２５を介して入隅水切りシート１９に粘着固定する。   After that, the waterproof sheet 23 of the sheet-like waterproof accessory 22 is attached to the sleeve wall body W. In other words, the release sheets 24 a and 25 a of the sheet-like waterproof accessory 22 are released from the adhesive layers 24 and 25 of the waterproof sheet 23. Then, the waterproof sheet 23 from which the release sheets 24a and 25a have been peeled off, the outer surface side vertical sheet portion 23a, the horizontal sheet portion 23b, and the floorboard side vertical sheet portion 23c through the adhesive layer 24, the outer surface of the sleeve wall body W, the finishing material The adhesive is fixed to the upper surface of 16, the horizontal portion 17 b of the waterproof paper 17, and the standing portion 17 a of the waterproof paper 17. On the other hand, the waterproof sheet 23 is adhesively fixed to the entrance corner draining sheet 19 through the adhesive layer 25 by the wall mounting sheet portion 23 d.

次に、袖壁本体Ｗの外面側に図３に示したような外装仕上パネル（化粧板）２６を取り付ける。この外装仕上パネル２６の上端部外面に付庇２８を図示しない皿木ビス等で固定する。そして、付庇２８の両側面とこれに対向する部分との間には変成シリコン材（図示せず）を防水のために充填し、付庇２８を縦板部２８ａの上端部に固定している皿木ビスの頭部にも変成シリコン材を塗布して防水する。更に、防水テープ３０の両端部を庇部２８ｂの先端面と屋根床板１８のフランジ１８ａの外面とに粘着固定して、付庇２８の上面と袖壁本体Ｗの上面を防水テープ３０で覆う。   Next, an exterior finishing panel (decorative board) 26 as shown in FIG. 3 is attached to the outer surface side of the sleeve wall main body W. A hook 28 is fixed to the outer surface of the upper end portion of the exterior finish panel 26 with a not-shown countersunk screw or the like. And between the both side surfaces of the hook 28 and the portions facing it, a modified silicon material (not shown) is filled for waterproofing, and the hook 28 is fixed to the upper end of the vertical plate portion 28a. Apply a modified silicone material to the head of the timber screw to keep it waterproof. Further, both end portions of the waterproof tape 30 are adhesively fixed to the front end surface of the flange portion 28 b and the outer surface of the flange 18 a of the roof floor plate 18, and the upper surface of the hook 28 and the upper surface of the sleeve wall body W are covered with the waterproof tape 30.

そして、防水テープ３０上には断面Ｌ字状の壁当たり板金３１を載置し、防水テープ３０のフランジ１８ａ側の端部外面に壁当たり板金３１の一端に設けた縦板部３１ａを当接させる。次に、この壁当たり板金３１の上面は、鋼板を塩化ビニールで被覆した笠木板金３２によりカバーする。この後、付庇２８の挿通孔３３に箱樋３４を取り付けて、この箱樋３４を排水溝１８ｂに接続し、この箱樋３４に集水用の角マス３５を接続し、この角マス３５に縦樋３６を取り付ける。
（２）入隅防水構造の作用
上述した入隅防水構造において屋根床板１８上に降った雨水は、屋根床板１８の傾斜に沿って矢印Ｂ方向に流れ、屋根床板１８の外壁２ａ側の排水溝１８ｂに捕集された後、箱樋３４，角マス３５及び縦樋３６を介して排水される。 A sheet metal 31 having a L-shaped cross section is placed on the waterproof tape 30, and a vertical plate portion 31 a provided at one end of the wall metal sheet 31 is brought into contact with the outer surface of the end of the waterproof tape 30 on the flange 18 a side. Let Next, the upper surface of the sheet metal 31 per wall is covered with a headboard sheet metal 32 in which a steel sheet is covered with vinyl chloride. Thereafter, a box rod 34 is attached to the insertion hole 33 of the attachment rod 28, the box rod 34 is connected to the drainage groove 18 b, and a water collecting square mass 35 is connected to the box rod 34. Attach the downpipe 36.
(2) Action of the entrance corner waterproof structure Rainwater that has fallen on the roof floor board 18 in the entrance corner waterproof structure described above flows in the direction of arrow B along the inclination of the roof floor board 18, and the drainage groove on the outer wall 2 a side of the roof floor board 18. After being collected in 18 b, it is drained through the box cage 34, the square mass 35 and the vertical rod 36.

一方、外壁２ａに貼り付けた入隅水切りシート１９と笠木板金３２との間に浸入する雨水の一部は、シート状防水役物２２の壁取付シート部２３ｄに沿って屋根床板１８側に流れた後、排水溝１８ｂに捕集されて、箱樋３４，角マス３５及び縦樋３６を介して排水される。また、入隅水切りシート１９と笠木板金３２との間に浸入する雨水の残りは袖壁本体Ｗの外面に沿って流下する。   On the other hand, part of the rainwater that enters between the corner draining sheet 19 attached to the outer wall 2a and the headboard sheet metal 32 flows along the wall mounting sheet portion 23d of the sheet-shaped waterproofing member 22 toward the roof floor board 18 side. After that, it is collected in the drain groove 18b and drained through the box rod 34, the square mass 35 and the vertical rod 36. Further, the remainder of the rainwater that enters between the entrance corner draining sheet 19 and the headboard sheet metal 32 flows down along the outer surface of the sleeve wall main body W.

このように建物側外壁面材下から防水シート（入隅水切りシート１９）を出してきて、出窓（ボウウインドウ５）側からも防水シート２３を出してジョイントする。複雑な形状部では下地材に対し防水シート先端の役物形状防水テープを貼り付けることにより、防水をする。下地であれば接着する防水テープに制限は少ない。役物部は現地でカバーをつけ、防水性能を保持する。   In this way, the waterproof sheet (filled corner draining sheet 19) is taken out from under the building-side outer wall surface material, and the waterproof sheet 23 is also taken out from the exit window (bow window 5) side to be jointed. In a complicated shape portion, waterproofing is performed by attaching an accessory-shaped waterproof tape at the tip of the waterproof sheet to the base material. There are few restrictions on the waterproof tape to be bonded if it is a base. The accessory section will be covered locally to maintain waterproof performance.

また、複雑な形状の防水ラインに対して、防水ラインを簡易化し、シートを建物外壁側からと出窓側から出し、それぞれのシート先端部の粘着層同士を貼り合せることにより防水ラインを形成する。複雑に防水ラインが入り組む部分は出窓側から出すシートを形状にあわせ役物化し、下地に対して貼りつける。出窓屋根面は仕上材（笠木板金３２）をつけるため、防水耐久性能上も、意匠上も問題ない。
（変形例）
また、図１３に示したようにシート状防水役物３７の防水シート３８を上下に二分割して縦水切りシート３９と上部水切りシート４０とにし、この縦水切りシート３９と上部水切りシート４０とを接合シート４１で接合した構成としても良い。 Moreover, a waterproof line is formed by simplifying a waterproof line with respect to the waterproof line of a complicated shape, taking out a sheet | seat from the building outer wall side and a bay window side, and bonding the adhesive layers of each sheet | seat front-end | tip part together. The part where the waterproof line is intricately complicated is made into a role by matching the sheet from the bay window to the shape, and is attached to the base. Since the finishing window (headwood sheet metal 32) is attached to the bay window roof surface, there is no problem in terms of waterproof durability and design.
(Modification)
