Description

【０００１】
【発明の属する技術分野】
本発明は、建物付設物の防水構造に係り、例えば、バルコニ、ベランダ、テラス、集合住宅用外階段、集合住宅用外廊下等に利用できるものである。
【０００２】
【背景技術】
建物付設物であるバルコニは建物の外壁部に設けられるため、雨仕舞い対策が施される。従来、床が複数のデッキ材の並設で形成されているバルコニでは、バルコニの構造材であってバルコニの外輪郭を形成する外輪郭部材となっている桁梁や妻梁のバルコニ内側に樋を配置し、デッキ材上に降った雨水をデッキ材上を流下させてこの樋に落下させ、そして、バルコニの外部に排出させるようしている。
【０００３】
【発明が解決しようとする課題】
しかし、バルコニの床が、例えば防水パン等のように、それ自身に排水部が設けられている床部材で形成される場合には、この床部材とバルコニの外輪郭部材との間に水切り部材を配設し、この水切り部材上及び床部材上に降った雨水を床部材の排水部から排水することになるが、この場合には、バルコニの外輪郭部材側に配設される水切り部材の端部について、雨水等の水に対する防水構造を工夫することが求められる。
【０００４】
本発明の目的は、建物付設物の外輪郭部材側に配設される水切り部材の端部に関して高度の防水性を確保できるようになる建物付設物の防水構造を提供するところにある。
【０００５】
【課題を解決するための手段】
本発明に係る建物付設物の防水構造は、建物付設物の外輪郭を形成する外輪郭部材と、前記建物付設物の床を形成する床部材との間に水切り部材が配設され、前記外輪郭部材に建物付設物内側に向かって突出する突片部が形成されているとともに、この突片部の下において前記水切り部材の外輪郭部材側の端部が前記外輪郭部材に配設されていることを特徴とするものである。
【０００６】
この建物付設物の防水構造によると、建物付設物の外輪郭を形成する外輪郭部材に建物付設物内側に向かって突出する突片部が形成され、この突片部の下において水切り部材の外輪郭部材側の端部が外輪郭部材に配設されているため、突片部が水切り部材の端部の上部を覆う庇となり、このため、建物付設物の外輪郭部材側に配設される水切り部材の端部に関して高度の防水性を確保できるようになる。
【０００７】
この建物付設物の防水構造において、外輪郭部材の突片部は建物付設物内側に向かって水平に延びるものでもよく、登り傾斜又は下り傾斜で延びるものでもよい。
【０００８】
また、この建物付設物の防水構造において、建物付設物の外輪郭部材と水切り部材の外輪郭部材側の端部との関係は、この水切り部材の外輪郭部材側の端部を外輪郭部材に配設するだけでもよく、また、外輪郭部材に突片部よりも下において水切り部材の端部を載せる受け部を設け、この受け部に載せられた水切り部材の外輪郭部材側の端部を外輪郭部材に配設するようにしてもよい。
【０００９】
後者によると、水切り部材の外輪郭部材側の端部が外輪郭部材の突片部の下に配設されても、水切り部材は外輪郭部材の受け部に載せられるため、床部材にかかる人間等の重量が水切り部材に作用しても、この重量を水切り部材は充分受けることができる。
【００１０】
また、本発明に係る建物付設物の防水構造は、建物付設物の外輪郭を形成する外輪郭部材と、前記建物付設物の床を形成する床部材との間に水切り部材が配設され、前記外輪郭部材に基端部よりも先端部が高位となった堤部が形成されているとともに、前記先端部を越えて建物付設物外側へ延びる前記水切り部材の外輪郭部材側の端部が前記堤部の建物付設物外側の面に配設されていることを特徴とするものである。
【００１１】
この建物付設物の防水構造によると、建物付設物の外輪郭を形成する外輪郭部材には、基端部よりも先端部が高位となった堤部が形成され、この先端部を越えて建物付設物外側へ延びる水切り部材の外輪郭部材側の端部が堤部の建物付設物外側の面に配設されているため、水切り部材の外輪郭部材側の端部の上に降った雨水は、この端部が、堤部の建物付設物外側の面と同じく建物付設物外側へ向いていることから、建物付設物外側へ排出されることになる。このため、建物付設物の外輪郭部材側に配設される水切り部材の端部に関して高度の防水性を確保できることになる。
【００１２】
この建物付設物の防水構造において、堤部は、堤部の建物付設物外側の面が建物付設物の内側に向かって登り傾斜したものでもよく、また、外輪郭部材から垂直に立ち上がったものでもよく、さらには建物付設物外側に向かって登り傾斜したものでもよく、堤部の形状やその傾斜方向は任意である。
【００１３】
以上の本発明において、建物付設物の外輪郭を形成する外輪郭部材に対する水切り部材の端部の配設は、当接でもよく、隙間を開けた対向配置でもよく、結合でもよく、その配設形態は任意である。
【００１４】
また、外輪郭部材に水切り部材の端部を結合する場合には、この結合は、ビスやリベット、ボルト・ナット等の止着具を用いて行ってもよく、接着剤や溶接により行ってもよく、外輪郭部材と水切り部材の一方に突起や凸部を設けるとともに、他方に孔や凹部、溝を設け、これら同士の係合、係止、嵌合、引っ掛け等によって行ってもよい。
【００１５】
また、外輪郭部材に対する水切り部材の端部の結合を、外輪郭部材や水切り部材を貫通する止着具を用いて行う場合には、この止着具の頭部を防水用シーリング材で覆ってもよく、外輪郭部材と水切り部材との間に防水用シーリング材を介入させてもよい。
【００１６】
これによると、止着具が挿入される孔からの雨水等の水の漏れを防止できる。
【００１７】
以上のように、建物付設物の外輪郭を形成する外輪郭部材と床部材との間に水切り部材を配設する本発明は、水切り部材の上に降った雨水等の水を排水するための排水部が外輪郭部材の内側に配置された床部材に形成されている場合に特に有効であるが、本発明はこれに限らず、床部材とは別に樋等の排水部材が外輪郭部材の内側等に配置されている場合にも有効である。
【００１８】
また、床部材を排水部が形成されているものとする場合において、その床部材の一例は、排水口が設けられている防水パンである。
【００１９】
このように床部材を防水パンとする場合には、水切り部材の外輪郭部材側に配設される端部とは反対側の端部を、防水パンの端部に形成されている立上部の内側に上から係止させる。これにより、水切り部材における防水パン側の端部の防水性も確保できることになる。
【００２０】
外輪郭部材はアルミ合金や合成樹脂、木粉混入の合成樹脂等の引き抜き成形品又は押し出し成形品でもよく、鋼板やステンレス板等の板金の折り曲げ品でもよく、アルミダイキャスト等の鋳造品でもよく、鍛造品でもよく、鋼板やステンレス板等の材料のプレス成形品でもよく、さらには、異種材料の複合品でもよい。
【００２１】
しかし、外輪郭部材をアルミ合金の引き抜き成形品又は押し出し成形品とすると、外輪郭部材に設ける前述の突片部や受け部、堤部をこの引き抜き成形時や押し出し成形時に外輪郭部材の長手方向に亘って連続して形成でき、水切り部材の長手方向に延びる突片部や受け部、堤部の成形加工を容易に行える。
【００２２】
以上の本発明は任意な建物付設物に適用でき、その建物付設物は、例えば、バルコニでもよく、ベランダでもよく、テラスでもよく、集合住宅用外階段でもよく、集合住宅用外廊下等でもよい。
【００２３】
また、これらの建物付設物は柱付きのものでもよく、柱なしのものでもよい。
【００２４】
また、建物付設物の外輪郭を形成する外輪郭部材は建物付設物の骨組みを形成する妻梁や桁梁等の構造材でもよく、この構造材に取り付けられるカバーや化粧材でもよい。
【００２５】
なお、本発明に係る建物付設物の防水構造は、建物付設物上に降る雨水に特に有効であるが、これ以外の水、、例えば、洗濯物を干すときに生ずる洗濯水や真夏等のときにまく打ち水等に対しても有効である
【００２６】
【発明の実施の形態】
以下に本発明の一実施形態を図面に基づいて説明する。本実施形態に係る建物付設物はバルコニであり、図１は、建物１に付設されたこのバルコニ２の全体を示す斜視図であり、バルコニ２は、床２Ａと、床２Ａの外輪郭部に立設された手摺り２Ｂとからなる。バルコニ２の平面図である図８に示すとおり、床２Ａの外輪郭は、バルコニ２が付設されている建物１のサイディング等の外面部材１Ａと、建物１から平行に延設され、バルコニ２の構造材となっている左右の妻梁３，４と、これらの妻梁３，４の先端間に架設され、バルコニ２の構造材となっている桁梁５とによって平面四角形に形成され、左右の妻梁３，４は、床２Ａの外輪郭のうちの左右の側部外輪郭を形成する側部外輪郭部材となっており、桁梁５は、床２Ａの外輪郭のうちの前部外輪郭を形成する前部外輪郭部材となっている。妻梁３，４と桁梁５は、押し出し成形又は引き抜き成形によるアルミ合金製である。
【００２７】
また、図８で示すように、建物１には左右２本のアーム部材６が設けられ、これらのアーム部材６の基端部材６Ａは、外面部材１Ａの背後に配置されている建物１の構造材である柱１Ｂに止着具７で連結され、外面部材１Ａを貫通したアーム部材６の本体６Ｂに妻梁３，４が結合されている。このため、左右の妻梁３，４はアーム部材６を介して建物１に結合されている。
【００２８】
また、図８で示されているとおり、床２Ａの内側には、床受け部材である複数本の根太８が桁梁５の長手方向に並設され、これらの根太８は、図１のＳ２−Ｓ２線断面図である図２に示されているように、一方の端部が建物１に取り付けられたアングル材による根太受け部材９に、他方の端部が桁梁５に形成されている突条５Ａにそれぞれ載せられてこれらの根太受け部材９、突条５Ａに止着具で結合されることにより、建物１と桁梁５との間に架設配置されている。
【００２９】
図２、及び図１のＳ５−Ｓ５線断面図である図５にも示されているとおり、それぞれの根太８の上には床部材である防水パン１０が載せられ、図８で示されているように平面四角形となっているこの防水パン１０は、建物１の外面部材１Ａと左右の妻梁３，４と桁梁５とで形成される床２Ａの外輪郭の内側において、図２及び図８で示されている前後の取付部材１１，１２により建物の外面部材１Ａと桁梁５との間の所定位置に位置決めされて配置されている。
【００３０】
これを具体的に説明すると、図２における桁梁５の周辺部分の拡大図である図３に示すように、前側の取付部材１１の上部の下向きに開口した係止部１１Ａによって防水パン１０の前側立上部１０Ａが係止されているとともに、この取付部材１１の下端平坦部は止着具１３で根太８の上面に止着され、また、図２における前記根太受け部材９の周辺部分の拡大図である図４に示されているように、後側の取付部材１２の上部の下向きに開口した係止部１２Ａによって防水パン１０の後側立上部１０Ｂが係止されているとともに、この取付部材１２の下端平坦部は止着具１３で根太８の上面に止着されている。
【００３１】
すなわち、平面四角形の防水パン１０は、建物の外面部材１Ａと平行をなす建物前後方向の２辺において、取付部材１１，１２により根太８に取り付けられている。
【００３２】
取付部材１１，１２による防水パン１０のこの取付状態では、図４に示されているとおり、後側の取付部材１２は建物１の外面部材１Ａに当接しているため、建物１の外面部材１Ａと桁梁５との間における防水パン１０の配置位置は、外面部材１Ａと桁梁５との間の方向における取付部材１２の寸法によって自ずと決り、この方向へは防水パン１０の配置位置が変更不能となっている。これに対して、取付部材１１，１２の係止部１１Ａ，１２Ａと防水パン１０の立上部１０Ａ，１０Ｂとはスライド自在であるため、左右の妻梁３と４の間における防水パン１０の配置位置は変更可能になっている。言い換えると、防水パン１０の配置位置は、桁梁５の長手方向へ調整自在である。
【００３３】
図８で示されているように、防水パン１０には排水部である複数個の排水口１４が設けられ、図２に示すとおり、防水パン１０の傾斜した歩行面における底部に設けられたこれらの排水口１４には、根太８と軒天部材１５との間に配管された排水管１６の一端が接続され、この排水管１６の他端には軒天部材１５を貫通した縦樋１７が接続されている。
【００３４】
また、図８で示されているように、防水パン１０と左側の妻梁３との間には第１水切り部材２１が配置され、防水パン１０と右側の妻梁４との間には第２水切り部材２２が配置され、防水パン１０と桁梁５との間には第３水切り部材２３が配置され、防水パン１０と建物１の外面部材１Ａとの間には第４水切り部材２４が配置されている。これらの水切り部材２１〜２４同士の接続箇所には、接続用水切り部材２５が配置され、これらの接続用水切り部材２５によって水切り部材２１〜２４の連続性が確保されている。
【００３５】
平面四角形となっている防水パン１０のそれぞれの縁部に配置される水切り部材２１〜２４の形状や、水切り部材２１〜２４と防水パン１０との関係等は、図３、図４、図６、図７に示され、これらの図のうち、図６と図７は、図５における左右の妻梁３，４の周辺部分の拡大図である。図６で示されている第１水切り部材２１、図７で示されている第２水切り部材２２、図３で示されている第３水切り部材２３、図４で示されている第４水切り部材２４のそれぞれは、防水パン１０側へ下り勾配で傾斜した本体部２１Ａ，２２Ａ，２３Ａ，２４Ａと、本体部２１Ａ，２２Ａ，２３Ａ，２４Ａの防水パン１０側における端部となっている垂下部２１Ｂ、２２Ｂ、２３Ｂ、２４Ｂと、本体部２１Ａ，２２Ａ，２３Ａ，２４Ａの防水パン１０側とは反対側における端部、すなわちバルコニ２の床２Ａの外輪郭を形成する外輪郭部材となっている妻梁３，４側、桁梁５側、建物１の外面部材１Ａ側の端部となっている起立部２１Ｃ，２２Ｃ，２３Ｃ，２４Ｃとからなる。
【００３６】
図３、図６、図７で示す第１〜第３水切り部材２１〜２３の垂下部２１Ｂ，２２Ｂ，２３Ｂは、防水パン１０の左側立上部１０Ｃ、右側立上部１０Ｄ、前側立上部１０Ａのそれぞれの内側に防水部材２６を介して係止され、第１〜第３水切り部材２１〜２３の起立部２１Ｃ，２２Ｃ，２３Ｃは、左右の妻梁３，４の上部におけるバルコニ内側の面と、桁梁５の上部におけるバルコニ内側の面とに形成されている凹部３Ｂ，４Ｂ，５Ｂに挿入されているとともに、これらの起立部２１Ｃ，２２Ｃ，２３Ｃは止着具２７で左右の妻梁３，４、桁梁５に止着されている。そして、起立部２１Ｃ，２２Ｃ，２３Ｃは凹部３Ｂ，４Ｂ，５Ｂに充填された不定形性のシーリング材２８で隠され、これらのシーリング材２８により、止着具２７が挿入されている起立部２１Ｃ，２２Ｃ，２３Ｃの孔と凹部３Ｂ，４Ｂ，５Ｂの孔の水密性が確保されている。
【００３７】
また、図４で示す第４水切り部材２４の垂下部２４Ｂは、防水パン１０の後側立上部１０Ｂの内側に係止されているとともに、第４水切り部材２４の起立部２４Ｃは建物１の外面部材１Ａに当接され、本体部２４Ａと起立部２４Ｃとの間の部分に打ち込まれた止着具２９により第４水切り部材２４は建物１に固定されている。この第４水切り部材２４の起立部２４Ｃの上面には、外面部材１Ａとの間で凹部を形成する段部２４Ｄが設けられており、この凹部に不定形性のシーリング材３０が充填されることによって第４水切り部材２４と外面部材１Ａとの間の水密性が確保されている。また、止着具２９の頭部にも不定形性のシーリング材が塗布されている。
【００３８】
以上において、第３及び第４水切り部材２３，２４は、防水パン１０を根太８に取り付けるための前記取付部材１１，１２の上から防水パン１０に被せられるものとなっている。
【００３９】
以上の本実施形態において、建物１の外面部材１Ａと左右の妻梁３，４と桁梁５とにより形成される床２Ａの外輪郭の内側に防水パン１０を配置し、第１〜第４水切り部材２１〜２４を施工して床２Ａを組み立てる作業は、次ぎのように行われる。
【００４０】
先ず、床２Ａの外輪郭の内側において、複数本の根太８を前記根太受け部材９と桁梁５の突条５Ａとの間に架設し、これらの根太８を根太受け部材９と突条５Ａとに止着具で固定する。そして、根太８の上に防水パン１０を載せ、この防水パン１０を前述した前後の取付部材１１，１２によって根太８に取り付ける作業を行う。この取付作業を行うと、前述したとおり、後側の取付部材１２は建物１の外面部材１Ａに当接しているため、防水パン１０は外面部材１Ａと桁梁５との間の所定位置に配置されることになる。このときにおける防水パン１０の配置位置は、防水パン１０と桁梁５との間隔が、左側の妻梁３と右側の妻梁４との間に配置されている防水パン１０と妻梁３との間隔（第１間隔）と、防水パン１０と妻梁４との間隔（第２間隔）とを同じにしたときにおけるこれらの第１及び第２間隔と同じ大きさとなる位置である。
【００４１】
以上により、防水パン１０は、建物１の外面部材１Ａと桁梁５との間における位置が取付部材１１，１２で変更不能に、かつ左右の妻梁３と４の間における位置が変更可能になって配置される。
【００４２】
この後、防水パン１０を取付部材１１，１２に対して左右方向へスライドさせ、これにより左右の妻梁３と４の間における防水パン１０の位置を調整し、防水パン１０と妻梁３との第１間隔と、防水パン１０と妻梁４との第２間隔とを同じにする。
【００４３】
次いで、第１〜第４水切り部材２１〜２４を防水パン１０と妻梁３，４、桁梁５、建物１の外面部材１Ａとの間に配設する作業、すなわち、第１〜第３水切り部材２１〜２３の垂下部２１Ｂ，２２Ｂ，２３Ｂを防水部材２６を介して防水パン１０の立上部１０Ａ，１０Ｃ，１０Ｄの内側に入れること、第４水切り部材２４の垂下部２４Ｂを防水パン１０の立上部１０Ｂの内側に入れること、第１〜第３水切り部材２１〜２３の起立部２１Ｃ，２２Ｃ，２３Ｃを妻梁３，４と桁梁５の凹部３Ｂ，４Ｂ，５Ｂに挿入して止着具２７で止着具すること、第４水切り部材２４の起立部２４Ｃを建物１の外面部材１Ａに当てて止着具２９で止着することをそれぞれ行い、凹部３Ｂ，４Ｂ，５Ｂと第４水切り部材２４の凹部２４Ｄにシーリング材２８，３０を充填し、また、止着具２９の頭部にシーリング材を塗布し、それぞれの水切り部材２１〜２４の接続箇所に接続用水切り部材２５を配置する。
【００４４】
第１〜第４水切り部材２１〜２４についての以上の配置作業を行う際、取付部材１１，１２が配置されている防水パン１０の建物前後方向の２つの辺に配置される第３及び第４水切り部材２３，２４は、取付部材１１，１２の上から防水パン１０に被せられる。
【００４５】
以上において、前述したとおり、第１間隔と、第２間隔と、防水パン１０と桁梁５との間隔（第３間隔）とが同じ大きさになっているため、第１〜第４水切り部材２１〜２４のうち、第１〜第３水切り部材２１〜２３は、幅寸法が同じになっていて同一断面が連続している水切り部材用材料を所定寸法に切断することにより形成でき、これらの水切り部材２１〜２３についての材料の共通化を図ることができる。
【００４６】
図９は、それぞれ同じ構造となっている図３、図４、図６、図７における第１〜第３水切り部材２１〜２３の起立部２１Ｃ，２２Ｃ，２３Ｃの周辺を代表して示した図６の第１水切り部材２１の起立部２１Ｃの周辺の拡大図である。前述したとおり、妻梁３のバルコニ内側の面における上部にはバルコニ外側へ窪んだ凹部３Ｂが形成され、この凹部３Ｂに水切り部材２１の起立部２１Ｃが挿入されているとともに、起立部２１Ｃは止着具２７で妻梁３に結合され、凹部３Ｂにシーリング材２８が充填されている。
【００４７】
凹部３Ｂの上部は、バルコニ内側へ水平に延びる突片部３Ｃとなっており、水切り部材２１の起立部２１Ｃは、この突片部３Ｃの下において妻梁３に結合されているため、突片部３Ｃで上方が覆われた状態となっている。また、凹部３Ｂの下面はバルコニ内側へ下り勾配で傾斜した受け部３Ｄとなっており、この受け部３Ｄに水切り部材２１の前記本体部２１Ａが載せられている。
【００４８】
以上において、雨天時に雨がバルコニ２上に降ると、水切り部材２１上に降った雨水は、水切り部材２１の本体部２１Ａが防水パン１０側へ下り傾斜しているため、防水パン１０側へ流れ、防水パン１０上に降った雨水と共に防水パン１０の傾斜している歩行面を流下して排水口１４に達し、排水管１６から縦樋１７を経てバルコニ２の外部へ排出される。また、妻梁３上に降った雨水のうち、妻梁３のバルコニ内側の端部、すなわち妻梁３の前記突片部３Ｃに達した雨水は、妻梁３に結合されている水切り部材２１の妻梁３側の端部となっている起立部２１Ｃが突片部３Ｃで覆われた状態になっているため、そのまま水切り部材２１の本体部２１Ａ上へ落下し、これ以後、上述と同様にしてバルコニ２の外部へ排出される。
【００４９】
このように本実施形態によると、妻梁３にバルコニ内側に突出した突片部３Ｃを設け、水切り部材２１の起立部２１Ｃをこの突片部３Ｃの下において妻梁３に結合したため、バルコニ２上に降って妻梁３上をバルコニ内側へ流れる雨水について、突片部３は、水切り部材２１の起立部２１Ｃにとっての庇となる。このため、バルコニ２の構造上、水切り部材２１における妻梁３との結合端部に関して高度の防水性を確保できることになる。
【００５０】
また、起立部２１Ｃが挿入されている妻梁３の凹部３Ｂにはシーリング材２８が充填されて止着具２７の頭部が覆われているため、起立部２１Ｃに止着具２７が貫通した孔が形成されていても、この孔を通って雨水が水切り部材２１の下等へ漏れることはない。
【００５１】
また、妻梁３には突片部３Ｃの下に受け部３Ｄが設けられ、この受け部３Ｄに水切り部材２１の本体部２１Ａの端部が載せられているため、建物１内からバルコニ２に出る人間等の重量が水切り部材２１に作用しても、水切り部材２１にかかるこの重量を水切り部材２１を介して妻梁３及び防水パン１０で支持させることができ、水切り部材２１にかかる各種の荷重を有効に受けることができる。
【００５２】
さらに、妻梁３はアルミ合金の引く抜き成形品又は押し出し成形品であるため、水切り部材２１の長手方向に連続する凹部３Ｂ、突片部３Ｃ、受け部３を引き抜き成形時又は押し出し成形時に容易に成形でき、引き抜き成形時又は押し出し成形で形成される妻梁３にとって好都合の防水構造とすることができる。
【００５３】
次に、本発明に係るそれぞれの別実施形態を説明する。
【００５４】
以下に説明するそれぞれの別実施形態は、図９の実施形態と同じく、左右の妻梁の部分と、これらの妻梁の先端間に架設される桁梁の部分とに適用される水切り部材のうち、これらの水切り部材を代表して左側の妻梁の部分に適用される水切り部材についてである。
【００５５】
図１０の実施形態では、妻梁３の凹部３Ｂと水切り部材２１の起立部２１Ｃとの間に防水テープ等による定形性のシーリング材３１を配置し、起立部２１Ｃを妻梁３に結合するための止着具２７をこのシーリング材３１に挿通させた。
【００５６】
この実施形態によると、止着具２７が貫通した起立部２１Ｃの孔に雨水が侵入しても、雨水のこれ以上の侵入はシーリング材３１で止められるため、雨水が水切り部材２１の下等へ漏れるのを防止でき、図９の実施形態と同様に、水切り部材２１と妻梁３との結合個所の水密性を確保できる。
【００５７】
また、この実施形態によると、水切り部材２１を妻梁３と防水パン１０との間に配置する前に起立部２１Ｃのバルコニ外側の面にシーリング材３１を貼り付けた後、止着具２７で起立部２１Ｃを妻梁３に止着することにより、水切り部材２１と妻梁３との結合作業と、水切り部材２１と妻梁３との結合個所の水密性を確保する作業とを同時に行え、作業性を向上させることができる。
【００５８】
図１１の実施形態では、妻梁３３のバルコニ内側の面の上部にバルコニ外側方向への深さを有する溝３３Ｂを形成し、この溝３３Ｂの上部を突片部３３Ｃとしている。一方、水切り部材４１の妻梁３３側の端部は水平部４１Ｃとなっており、上面に定形性のシーリング材３１を貼り付けたこの水平部４１Ｃを溝３３Ｂに挿入した後、突片部３３Ｃの上面から挿入した止着具２７で水切り部材４１を妻梁３３に結合している。
【００５９】
この実施形態でも、突片部３３Ｃは水切り部材４３の水平部４３Ｃにとっての庇となり、また、溝３３Ｂの下面は水切り部材４１を載せるための受け部３３Ｄとなる。そして、シーリング材３１によって雨水が水切り部材４１の下面等に漏れることが防止される。
【００６０】
図１２の実施形態では、水切り部材２１の起立部２１Ｃが挿入される妻梁４３の凹部４３Ｂの上部の突片部４３Ｃは、バルコニ内側へ水平に突出しておらず、登り傾斜で突出している。このため、この実施形態では、突片部４３Ｃ上に降った雨水は、バルコニ外側へ流下して妻梁４３から落下する。
【００６１】
なお、突片部４３Ｃをバルコニ内側へ登り傾斜させず、二点鎖線で示すように、バルコニ内側へ下り傾斜させることにより、突片部４３Ｃ上に降った雨水を水切り部材２１の本体部２１Ａへ落下させてもよい。
【００６２】
図１３の実施形態では、妻梁５３の上面におけるバルコニ内側の端部に堤部５３Ｂが形成されている。この堤部５３Ｂはバルコニ内側へ向かって登り傾斜しているため、登り始めの基端部５３Ｃよりも登り終わりの先端部５３Ｄは高位となっていて、この先端部５３Ｄから先は妻梁５３のバルコニ内側の側面である鉛直面となっている。水切り部材６１の妻梁５３側の端部は、堤部５３Ｂのバルコニ外側の面５３Ｅと対応する角度の傾斜部６１Ｃとなっており、この傾斜部６１Ｃが、シーリング材３1を介して堤部５３Ｂのバルコニ外側の面５３Ｅに止着具２７で結合されている。
【００６３】

Balconi, a building accessory, is installed on the outer wall of the building, so measures are taken to prevent rain. Conventionally, in a balconi where the floor is formed by arranging a plurality of deck materials side by side, it is placed inside the balconi of the girder beam or the twill beam, which is a structural material of the balcony and is an outer contour member that forms the outer contour of the balcony. The rainwater that has fallen on the deck material is allowed to flow down on the deck material, fall into this cage, and then discharged to the outside of the balconi.
[0003]
[Problems to be solved by the invention]
However, when the floor of the balconi is formed of a floor member provided with a drainage section, such as a waterproof pan, a draining member is provided between the floor member and the outer contour member of the balconi. The rainwater that has fallen on the drainage member and the floor member is drained from the drainage part of the floor member. In this case, the drainage member disposed on the outer contour member side of the balconi It is required to devise a waterproof structure against water such as rainwater at the end.
[0004]
An object of the present invention is to provide a waterproof structure for a building accessory that can secure a high degree of waterproofness with respect to an end portion of a draining member disposed on the outer contour member side of the building accessory.
[0005]
[Means for Solving the Problems]
In the waterproofing structure for a building accessory according to the present invention, a draining member is disposed between an outer contour member that forms an outer contour of the building accessory and a floor member that forms a floor of the building accessory. A projecting piece projecting toward the inside of the building attachment is formed on the contour member, and an end of the draining member on the outer contour member side is disposed on the outer contour member below the projecting piece. It is characterized by being.
[0006]
According to the waterproof structure of the building accessory, the outer contour member that forms the outer contour of the building accessory is formed with a protruding piece that protrudes toward the inside of the building accessory, and the drainage member is disposed below the protruding piece. Since the end portion on the contour member side is disposed on the outer contour member, the projecting piece portion becomes a ridge that covers the upper portion of the end portion of the draining member, and is therefore disposed on the outer contour member side of the building accessory. A high degree of waterproofness can be secured at the end of the draining member.
[0007]
In this waterproofing structure for a building accessory, the protruding piece of the outer contour member may extend horizontally toward the inside of the building accessory, or may extend in an upward or downward inclination.
[0008]
Moreover, in the waterproof structure of this building accessory, the relationship between the outer contour member of the building accessory and the end portion of the draining member on the outer contour member side is that the end portion of this draining member on the outer contour member side is the outer contour member. In addition, the outer contour member may be provided with a receiving portion for placing the end portion of the draining member below the protruding piece portion, and the end portion on the outer contour member side of the draining member placed on the receiving portion. It may be arranged on the outer contour member.

This is particularly effective when the drainage portion is formed on a floor member disposed inside the outer contour member. However, the present invention is not limited to this, and a drainage member such as a basin is provided separately from the floor member. It is also effective when arranged inside.
[0018]
Moreover, when the floor member is formed with a drainage part, an example of the floor member is a waterproof pan provided with a drain outlet.
[0019]
In this way, when the floor member is a waterproof pan, the end of the draining member opposite to the end disposed on the outer contour member side is the upright portion formed at the end of the waterproof pan. Lock inside from above. Thereby, the waterproofness of the edge part by the side of the waterproofing pan in a draining member can also be ensured.
[0020]
The outer contour member may be a pultruded or extruded product such as an aluminum alloy, a synthetic resin, or a synthetic resin mixed with wood powder, a bent product of a sheet metal such as a steel plate or a stainless steel plate, or a cast product such as an aluminum die cast. It may be a forged product, a press-formed product of a material such as a steel plate or a stainless steel plate, or a composite product of different materials.
[0021]
