Description

【０００１】
【発明の属する技術分野】
本発明は、建物付設物の床構造及びその床を施工する方法に係り、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の建物付設物の床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の床の施工作業は、建物から左右の妻梁を延設し、これらの妻梁の先端間に桁梁を架設することにより床の骨組みを形成し、この床の骨組みの内側に複数の根太を並設した後、これらの根太に防水パン等の床部材を載せることにより行われ、また、左右の妻梁と床部材との間、桁梁と床部材との間及び建物の外面部材と床部材との間に水切り部材を配置することにより、バルコニの床の雨仕舞い処理がなされる。
【０００３】
このため、バルコニの外輪郭は建物の外面部材と左右の妻梁と桁梁とによって形成され、左右の妻梁は、この外輪郭のうちの左右の側部外輪郭を形成する左右の側部外輪郭部材となっており、桁梁は、こ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。また、前記水切り部材は、左右の妻梁と床部材との間、桁梁と床部材との間、建物の外面部材と床部材との間に配置される中間部材となっている。
【０００４】
【発明が解決しようとする課題】
ところで、先端間に桁梁が架設される左右の妻梁は桁梁と共にバルコニの構造材となるものであるため、これらの妻梁の基端部は建物の柱等の構造材に結合されることになり、これらの構造材から左右の妻梁が建物外側へ延設され、これらの構造材の間隔は、その住宅製造会社等の建物製造会社で規定されている基本モジュールに基づいた寸法となっている。一方、防水パン等の床部材は建物部品であるため、この床部材は建物製造会社とは異なる建物部品製造会社によって生産され、この床部材の寸法は、この建物部品製造会社で規定されている基本モジュールに基づいた寸法となっている。
【０００５】
このため、バルコニが建物付設物となって付設される建物の基本モジュールと、バルコニの部品である床部材の基本モジュールとが異なることがあり、バルコニの左右の妻梁は建物の柱等の構造材に基端部が結合されるため、これらの妻梁の間隔は建物の基本モジュールに基づいた寸法となる。
【０００６】
このように、左右の妻梁の間隔についての基本モジュールと、床部材の寸法についての基本モジュールとが異なっている場合又はその他の場合において、床部材と左側の妻梁との間に配置される中間部材としての水切り部材と、床部材と右側の妻梁との間に配置される中間部材としての水切り部材のために、各種幅寸法の水切り部材を用意しておかなければならないおそれが生じ、それぞれのバルコニを施工する上で、寸法が異なる各種の水切り部材を用意しておかなければならないことは、部品生産、部品管理等の上で好ましくない。
【０００７】
本発明の目的は、水切り部材等の左右の中間部材を共通化でき、寸法を異ならせて用意しなければならない中間部材の種類を削減できる建物付設物の床構造及びその床施工方法を提供するところにある。
【０００８】
【課題を解決するための手段】
本発明に係る建物付設物の床構造は、建物付設物の床の外輪郭が、建物の外面部材と、この建物から延設された左右の側部外輪郭部材と、これらの側部外輪郭部材の先端間に架設された前部外輪郭部材とにより形成され、この外輪郭の内側に床部材が配置されるとともに、この床部材と前記左側の側部外輪郭部材との間に第１中間部材が、前記床部材と前記右側の側部外輪郭部材との間に第２中間部材がそれぞれ配置される建物付設物の床構造において、前記床部材と前記左側の側部外輪郭部材との間隔と、前記床部材と前記右側の側部外輪郭部材との間隔とが同じ又は略同じになっていることを特徴とするものである。
【０００９】
この建物付設物の床構造では、床部材と左側の側部外輪郭部材との間隔と、床部材と右側の側部外輪郭部材との間隔とが同じ又は略同じになっているため、たとえ、左右の側部外輪郭部材又はこれらの側部外輪郭部材が取り付けられた部材の基端部が結合される建物の柱等の構造材の間隔についての基本モジュールと、床部材の寸法についての基本モジュールとが異なっていても、床部材と左側の側部外輪郭部材との間に配置される第１中間部材と、床部材と右側の側部外輪郭部材との間に配置される第２中間部材とを同じ幅寸法のものとすることができ、すなわち、これらの中間部材を共通化することができる。
【００１０】
このため、予め用意しなければならない中間部材は、建物の柱等の構造材の間隔についての基本モジュールと床部材の寸法についての基本モジュールとに対応した寸法のものだけでよくなり、用意しなければならない寸法が異なる中間部材の種類を削減できる。
【００１１】
以上において、床部材と左側の側部外輪郭部材との間隔と、床部材と右側の側部外輪郭部材との間隔とが略同じになっているとは、床部材の配置位置等について多少の誤差があり、床部材と左側の側部外輪郭部材との間隔と、床部材と右側の側部外輪郭部材との間隔とが正確に同じになっていなくてもよいとの意味であり、この誤差が左右の中間部材を共通化できる範囲のものであれば、本発明の目的は達成できるため、このような誤差がある場合であっても、本発明では許容される。
【００１２】
本発明において、以下における「略同じ」とは、これと同じ意味である。
【００１３】
また、床部材と前記前部外輪郭部材との間に第３中間部材が配置される場合には、これらの床部材と前部外輪郭部材との間隔を、床部材と左側の側部外輪郭部材との間隔及び床部材と右側の側部外輪郭部材との間隔と同じ又は略同じとしてもよい。
【００１４】
これによると、第１中間部材と第２中間部材と第３中間部材を共通化できるようになり、床部材と前部外輪郭部材との間に第３中間部材が配置される場合においても、この第３中間部材の共通化も達成できる。
【００１５】
また、本発明において、前記床の外輪郭の内側に配置される床部材の配置位置は、建物の外面部材と前部外輪郭部材との間で変更不能であって、左側の側部外輪郭部材と右側の側部外輪郭部材との間でも変更不能であってもよいが、建物の外面部材と前部外輪郭部材との間で変更不能であるとともに、左側の側部外輪郭部材と右側の側部外輪郭部材との間では変更可能になっていることがより好ましい。
【００１６】
これによると、建物の外面部材と前部外輪郭部材との間で変更不能に配置された床部材の配置位置を、左側の側部外輪郭部材と右側の側部外輪郭部材との間で変更する作業を行えるようになり、床部材を左右方向へのみ移動させるこの作業により、床部材と左側の側部外輪郭部材との間隔と、床部材と右側の側部外輪郭部材との間隔とを容易に同じ又は略同じにできる。
【００１７】
なお、この作業を行う際に、床部材と前部外輪郭部材との間隔を、床部材と左側の側部外輪郭部材との間隔及び床部材と右側の側部外輪郭部材との間隔と同じ又は略同じにしておくことにより、第１中間部材と第２中間部材と第３中間部材を共通化できる。
【００１８】
また、床部材と建物の外面部材との間に第４中間部材が配置される場合において、これらの床部材と建物の外面部材との間隔も、床部材と左側の側部外輪郭部材との間隔及び床部材と右側の側部外輪郭部材との間隔と同じ又は略同じにしてもよく、これによると、第４中間部材も共通化できるようになる。
【００１９】
本発明に係る建物付設物の床施工方法は、建物の外面部材と、この建物から延設され、床部材との間に第１中間部材が配置される左側の側部外輪郭部材と、前記建物から延設され、前記床部材との間に第２中間部材が配置される右側の側部外輪郭部材と、これらの左右の側部外輪郭部材の先端間に架設される前部外輪郭部材とによって形成される床の外輪郭の内側に、前記床部材を、前記建物の外面部材と前記前部外輪郭部材との間における位置を変更不能にしかつ前記左側の側部外輪郭部材と前記右側の側部外輪郭部材との間における位置を変更可能にして配置し、この後、前記左側の側部外輪郭部材と前記右側の側部外輪郭部材との間における前記床部材の位置を調整することにより、この床部材と前記左側の側部外輪郭部材との間隔と、前記床部材と前記右側の側部外輪郭部材との間隔とを同じ又は略同じにすることを特徴とするものである。
【００２０】
この建物付設物の床施工方法によると、床部材が、建物の外面部材と前部外輪郭部材との間において位置を変更不能に、左側の側部外輪郭部材と右側の側部外輪郭部材との間において位置を変更可能にして配置された後、左側の側部外輪郭部材と右側の側部外輪郭部材との間における床部材の位置を調整することにより、床部材と左側の側部外輪郭部材との間隔と、床部材と右側の側部外輪郭部材との間隔とを同じ又は略同じにするため、床部材と左側の側部外輪郭部材との間に配置される第１中間部材と、床部材と右側の側部外輪郭部材との間に配置される第２中間部材とを幅寸法が同じになったものにして共通化することができる。
【００２１】
この建物付設物の床施工方法において、床部材と前部外輪郭部材との間に第３中間部材が配置される場合には、床部材と左側の側部外輪郭部材との間隔と、床部材と右側の側部外輪郭部材との間隔とを同じ又は略同じにするときに、床部材と前部外輪郭部材との間の間隔を、床部材と前記左側の側部外輪郭部材との間隔及び床部材と前記右側の側部外輪郭部材との間隔と同じ又は略同じにしておいてもよい。
【００２２】
これによると、第１中間部材と第２中間部材と第３中間部材を共通化できることになり、また、建物の外面部材と前部外輪郭部材との間における床部材の配置位置を定めてから、左側の側部外輪郭部材と右側の側部外輪郭部材との間における床部材の配置位置を定めるという作業を行えることになる。
【００２３】
また、床部材と建物の外面部材との間に第４中間部材が配置される場合には、床部材と左側の側部外輪郭部材との間隔と、床部材と右側の側部外輪郭部材との間隔とを同じ又は略同じにするときに、床部材と建物の外面部材との間の間隔を、床部材と左側の側部外輪郭部材との間隔及び床部材と右側の側部外輪郭部材との間隔と同じ又は略同じにしておいてもよい。
【００２４】
これによると、第４中間部材も共通化できることになる。
【００２５】
以上の本発明において、それぞれの中間部材は、水切り部材でもよく、床部材の見切り部材でもよく、左右の側部外輪郭部材や前部外輪郭部材等の見切り部材でもよく、床部材と左右の側部外輪郭部材や床部材と前部外輪郭部材との間等に配置される部材であれば、任意な部材でよい。
【００２６】
また、以上の本発明において、建物の外面部材は外壁でもよく、外壁に設けられる開閉用又は常時閉鎖の開口部のためのサッシ等の枠材でもよく、建物付設物が取り付けられる建物外面を形成するものであれば、任意な部材でよい。
【００２７】
また、本発明は任意な建物付設物に適用でき、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。
【００２８】
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。
【００２９】
また、床部材は、それ１個で建物付設物の床全体を形成するものでもよく、この場合における床部材の具体例の一つは防水パンであり、また、床部材は、デッキ材等のように、複数個並設されることにより床全体を形成するものでもよい。
【００３０】
また、床の外輪郭を形成する前記左右の側部外輪郭部材と前記前部外輪郭部材は、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。
【００３１】
【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、引き抜き成形又は押し出し成形によるアルミ合金製である。
【００３２】
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。
【００３３】
また、図８で示されているとおり、床２Ａの内側には複数本の根太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受け部材９、突条５Ａに結合されることにより、所定位置に配置されている。
【００３４】
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、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固定部材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。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、前側の固定部材１１の上部の係止部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、この固定部材１１は止着具１３で根太８に結合され、また、図２における前記受け部材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、後側の固定部材１２の上部の係止部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、この固定部材１２は止着具１３で根太８に結合されている。
【００３５】
このため、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の配置位置は変更不能となっており、これに対して、固定部材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。
【００３６】
図８で示されているように、防水パン１０には複数個の排水口１４が設けられ、これらの排水口１４には、図２で示すように、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。
【００３７】
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中間部材である第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中間部材である第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中間部材である第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中間部材である第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、水切り部材２１〜２４の連続性が確保されている。
【００３８】
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。また、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側における端部の垂下部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の起立部２１Ｃ、２２Ｃ、２３Ｃ、２４Ｃとからなる。
【００３９】
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、第１〜第３水切り部材２１〜２３と左右の妻梁３，４、桁梁５との間の水密性が確保されている。
【００４０】
なお、シーリング材２８は、不定形シーリング材でもよく、防水テープ等の定形シーリング材でもよい。シーリング材２８を定形シーリング材とする場合には、この定形シーリング材は、起立部２１Ｃ，２２Ｃ，２３Ｃと凹部３Ｂ，４Ｂ，５Ｂとの間に介入させてもよい。
【００４１】
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の頭部にもシーリング材が塗布されている。
【００４２】
図１で示したバルコニ２の手摺り２Ｂは、左右の妻梁３，４及び桁梁５に立設された複数本の柱４０と、互いに隣接するそれぞれの柱４０同士の間に架設されたパネル４１とで形成され、パネル４１は上下にも並設されている。図９は、柱４０の平断面図であり、図１０は、パネル４１の縦断面図である図９のＳ１０−Ｓ１０線断面図である。図９で示すように、パネル４１の両側面には枠部材４２が取り付けられ、この枠部材４２が柱４０の側面に形成されている開口溝４０Ａに嵌合されることにより、それぞれのパネル４１は隣接する柱４０同士の間に架設されている。
【００４３】
柱４０及びパネル４１のバルコニ外側の外面にはカバー４３，４４が被せられており、これらのカバー４３，４４は内外二層からなり、内層４３Ａ，４４ＡはＡＢＳ樹脂発泡材料製であり、外層４３Ｂ、４４Ｂは木粉を５％程度混入したＡＡＳ樹脂製である。
【００４４】
このため、バルコニ２の手摺り２Ｂは全体的に木をイメージさせる木目調となっているとともに、ＡＡＳ樹脂によって高耐候性を有している。
【００４５】
以上において、図８に示すように、前述したアーム部材６を介して左右の妻梁３，４が結合されている建物１の柱１Ｂ同士の間の距離はＬ１であり、これと同じ方向における防水パン１０の寸法はＬ２である。Ｌ１は、建物１の製造会社が独自に定めた基本モジュールに基づく長さであり、Ｌ２は、防水パン１０の製造会社が独自に規定した基本モジュールに基づく長さである。これらの基本モジュール同士に関連性はない。
【００４６】
また、図３、図６、図７に示されているように、断面形状が同じになっている第１〜第３水切り部材２１〜２３の幅寸法はＷ１であり、これに対して図４で示す第４水切り部材２４の幅寸法はＷ２である。すなわち、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、同一の水切り部材材料を所定の長さ寸法に切断することにより形成されており、これらの水切り部材２１〜２３は共通化されている。Ｗ１は、Ｌ１とＬ２との関係から算出された寸法である。
【００４７】
以上の本実施形態に係るバルコニ２の床構造において、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を施工する作業は、次ぎのように行われる。
【００４８】
先ず、床２Ａの外輪郭の内側に複数本並設されている根太８の上に防水パン１０を載せ、この防水パン１０を前述した前後の固定部材１１，１２によって建物１の外面部材１Ａと桁梁５との間の所定位置に配置する。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。
【００４９】
これにより、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固定部材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。
【００５０】
この後、防水パン１０を固定部材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。
【００５１】
これにより、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）とが同じになり、この後、これらの箇所に、幅寸法が共にＷ１となっていて共通化されている第１〜第３水切り部材２１〜２３を施工する作業を行い、また、防水パン１０と建物１の外面部材１Ａとの間隔に第４水切り部材２４を施工する作業を行う。
【００５２】
以上説明した本実施形態によると、バルコニ２が取付支持される建物１の柱１Ａ同士の距離Ｌ１についての基本モジュールと、防水パン１０の寸法Ｌ２についての基本モジュールとに関連性がなくても、バルコニ２の床２Ａの左側の側部外輪郭部材となっている妻梁３と防水パン１０との第１間隔と、右側の側部外輪郭部材となっている妻梁４と防水パン１０との第２間隔とを同じにしているため、これらの箇所に配置する第１水切り部材２１と第２水切り部材２２とを同じ幅寸法Ｗ１を有するものとして共通化でき、それぞれのバルコニの施工現場のために、Ｌ１とＬ２の組み合わせに基づく各種Ｗ１の寸法となった水切り部材を用意しておけばよいため、用意しなければならない水切り部材の種類を削減できる。
【００５３】
また、防水パン１０と桁梁５との間の第３間隔も第１間隔及び第２間隔と同じＷ１になっているため、この第３間隔の箇所に配置する第３水切り部材２３も共通化できる。
【００５４】
そして、建物１の外面部材１Ａと防水パン１０との間に配置される第４水切り部材２４は幅寸法がＷ２になっているために共通化されていないが、この第４水切り部材２４には、外面部材１Ａとの間でシーリング材３０を充填するための凹部を形成する段部２４Ｄが形成されているため、このシーリング材３０により、第４水切り部材２４と外面部材１Ａとの間の水密性を確保できる。
【００５５】
また、本実施形態によると、根太８の上に載せられてバルコニ２の床２Ａの内側に配置される防水パン１０は、前後の固定部材１１，１２で外面部材１Ａと桁梁５との間の配置位置が規定されているだけであって、左右の妻梁３と４の間における配置位置は変更可能になっているため、防水パン１０の左右方向への移動によって第１間隔と第２間隔とを同じにする作業を容易に行える。
【００５６】
さらに、防水パン１０を左右方向に移動させて第１間隔と第２間隔を同じにする作業を行うとき、防水パン１０は前後の固定部材１１，１２に対してスライド自在となっているため、固定部材１１，１２をガイド部材として防水パン１０を正確に左右方向へのみ移動させることができ、この作業の容易化を達成できる。
【００５７】
さらに、この作業を行うときには、固定部材１１，１２によって第３間隔は第１間隔及び第２間隔と同じになっており、第１間隔と第２間隔とを同じにする作業を終えたときには、これら３個の間隔は同じになっているため、防水パン１０を床２Ａの所定位置に配置する作業を効率的に行える。
【００５８】
なお、以上説明した実施形態では、Ｌ１とＬ２は互いに別となった基本モジュールに基づく寸法であったが、Ｌ１とＬ２が同じ基本モジュールに基づく寸法である場合にも、本発明は適用できる。
【００５９】
【発明の効果】
本発明によると、水切り部材等の左右の中間部材を共通化でき、寸法を異ならせて用意しなければならない中間部材の種類を削減できるという効果を得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a floor structure of a building accessory and a method for constructing the floor, and can be used for a floor of a building accessory such as a balcony, a veranda, a terrace, an outer staircase for an apartment house, an outer corridor for an apartment house, etc. It is.
[0002]
[Background]
The construction work of the balconi floor, which is an accessory to the building, consists of extending the left and right end beams from the building and laying the girder beams between the ends of these end beams to form a floor frame. A plurality of joists are placed side by side, and floor members such as waterproof pans are placed on these joists, and between the left and right end beams and floor members, between the girder beams and floor members. Further, by arranging a draining member between the outer surface member and the floor member of the building, the rain closing process of the balconi floor is performed.
[0003]
For this reason, the outer contour of the balconi is formed by the outer surface member of the building, the left and right end beams, and the girder beam, and the left and right end beams are the left and right side portions that form the left and right side outer contours of the outer contour. It is an outer contour member, and the girder is a front outer contour member that forms a front outer contour of the outer contour. The draining member is an intermediate member disposed between the left and right end beams and the floor member, between the beam and the floor member, and between the outer surface member and the floor member of the building.
[0004]
[Problems to be solved by the invention]
By the way, the left and right end beams where the girder is erected between the ends are the structural material of the balconies together with the beam, so the base ends of these end beams are connected to the structural material such as the pillar of the building. As a result, the left and right end beams are extended to the outside of the building from these structural materials, and the interval between these structural materials is based on the dimensions based on the basic modules specified by the building manufacturing company such as the housing manufacturing company. It has become. On the other hand, since floor members such as waterproof pans are building parts, the floor members are produced by a building parts manufacturing company different from the building manufacturing company, and the dimensions of the floor members are regulated by the building parts manufacturing company. The dimensions are based on the basic module.
[0005]
For this reason, the basic module of the building where Balconi is attached to the building may be different from the basic module of the floor member that is a part of Balconi. Since the base ends are joined to the material, the spacing between these beams is based on the building's basic module.
[0006]
In this way, in the case where the basic module for the distance between the left and right end beams and the basic module for the dimensions of the floor member are different or in other cases, it is arranged between the floor member and the left end beam. For the draining member as the intermediate member, and the draining member as the intermediate member disposed between the floor member and the right side beam, there is a possibility that it is necessary to prepare draining members of various width dimensions, In constructing each balconi, it is not preferable in terms of parts production, parts management, and the like to prepare various draining members having different dimensions.
[0007]
An object of the present invention is to provide a floor structure for a building accessory and a floor construction method for the same, in which left and right intermediate members such as a draining member can be shared, and the types of intermediate members that must be prepared with different dimensions can be reduced. By the way.
[0008]
[Means for Solving the Problems]
In the floor structure of a building accessory according to the present invention, the outer contour of the floor of the building accessory is an outer surface member of the building, left and right side outer contour members extending from the building, and these side outer contours. A front outer contour member provided between the front ends of the members, and a floor member is disposed inside the outer contour, and a first between the floor member and the left side outer contour member. In the floor structure of a building accessory in which a second intermediate member is disposed between the floor member and the right side outer contour member, the intermediate member, and the floor member and the left side outer contour member, And the interval between the floor member and the right side outer contour member are the same or substantially the same.
[0009]
In the floor structure of this building accessory, the distance between the floor member and the left side outer contour member and the distance between the floor member and the right side outer contour member are the same or substantially the same. Basic module about the interval of structural materials such as building pillars to which the base ends of the left and right side outer contour members or the members to which these side outer contour members are attached are coupled, and the dimensions of the floor members Even if the basic module is different, the first intermediate member disposed between the floor member and the left side outer contour member and the first intermediate member disposed between the floor member and the right side outer contour member. The two intermediate members can have the same width, that is, these intermediate members can be shared.
[0010]
For this reason, the intermediate members that must be prepared in advance need only have dimensions corresponding to the basic module for the interval between the structural members such as the pillars of the building and the basic module for the dimensions of the floor member. It is possible to reduce the types of intermediate members having different dimensions.
[0011]
In the above description, the distance between the floor member and the left side outer contour member and the distance between the floor member and the right side outer contour member are substantially the same. This means that the distance between the floor member and the left side outer contour member and the distance between the floor member and the right side outer contour member do not have to be exactly the same. Since the object of the present invention can be achieved if this error is within a range in which the left and right intermediate members can be used in common, the present invention allows even such an error.
[0012]
In the present invention, “substantially the same” in the following has the same meaning.
[0013]

The distance between the contour member and the distance between the floor member and the right side outer contour member may be the same or substantially the same.
[0014]
According to this, it becomes possible to share the first intermediate member, the second intermediate member, and the third intermediate member, and even when the third intermediate member is disposed between the floor member and the front outer contour member, This third intermediate member can also be shared.
[0015]
In the present invention, the arrangement position of the floor member arranged inside the outer contour of the floor cannot be changed between the outer surface member of the building and the front outer contour member, and the left side outer contour It may be unchangeable between the member and the right side outer contour member, but cannot be changed between the outer surface member of the building and the front outer contour member, and the left side outer contour member It is more preferable that the right side outer contour member can be changed.
[0016]
According to this, the arrangement position of the floor member arranged unchangeable between the outer surface member of the building and the front outer contour member is between the left side outer contour member and the right side outer contour member. The work to be changed can be performed, and this work of moving the floor member only in the left-right direction allows the distance between the floor member and the left side outer contour member and the distance between the floor member and the right side outer contour member. Can be easily made the same or substantially the same.
[0017]
When performing this operation, the distance between the floor member and the front outer contour member is determined by the distance between the floor member and the left side outer contour member and the distance between the floor member and the right side outer contour member. By making it the same or substantially the same, the first intermediate member, the second intermediate member, and the third intermediate member can be shared.
[0018]
Further, in the case where the fourth intermediate member is disposed between the floor member and the outer surface member of the building, the interval between the floor member and the outer surface member of the building is also set between the floor member and the left side outer contour member. The distance and the distance between the floor member and the right side outer contour member may be the same or substantially the same, and according to this, the fourth intermediate member can be shared.
[0019]

Between the floor member and the left side by adjusting the position of the floor member between the left side outer contour member and the right side outer contour member. In order to make the interval between the outer contour member and the interval between the floor member and the right side outer contour member the same or substantially the same, the first outer member disposed between the floor member and the left side outer contour member is arranged. The first intermediate member and the second intermediate member disposed between the floor member and the right side outer contour member can have the same width and can be used in common.
[0021]
In the floor construction method for building attachments, when the third intermediate member is disposed between the floor member and the front outer contour member, the distance between the floor member and the left side outer contour member, When the distance between the member and the right side outer contour member is the same or substantially the same, the distance between the floor member and the front outer contour member is the floor member and the left side outer contour member. And the interval between the floor member and the right side outer contour member may be the same or substantially the same.
[0022]

That is, among the first to fourth draining members 21 to 24, the first to third draining members 21 to 23 are formed by cutting the same draining member material into a predetermined length, and these The draining members 21 to 23 are made common. W1 is a dimension calculated from the relationship between L1 and L2.
[0047]
In the floor structure of the balconi 2 according to the above-described embodiment, the waterproof pan 10 is disposed inside the outer contour of the floor 2A formed by the outer surface member 1A of the building 1, the left and right end beams 3, 4 and the girder beam 5. And the operation | work which constructs the 1st-4th draining members 21-24 is performed as follows.
[0048]
First, the waterproof pan 10 is placed on the joists 8 arranged in parallel inside the outer contour of the floor 2A, and the waterproof pan 10 is attached to the outer surface member 1A of the building 1 by the front and rear fixing members 11 and 12 described above. It arrange | positions in the predetermined position between the beam beams 5. FIG. The position of the waterproof pan 10 at this time is such that the distance between the waterproof pan 10 and the girder 5 is between the left span beam 3 and the right span beam 4. This is the position having the same size as the first and second intervals when the interval (first interval) and the interval between the waterproof pan 10 and the end beam 4 (second interval) are the same.
[0049]
Thereby, the waterproof pan 10 cannot change the position between the outer surface member 1A of the building 1 and the girder 5 with the fixing members 11 and 12, and can change the position between the left and right end beams 3 and 4. Arranged.
[0050]
Thereafter, the waterproof pan 10 is slid in the left-right direction with respect to the fixing members 11 and 12, thereby adjusting the position of the waterproof pan 10 between the left and right end beams 3 and 4. The first interval and the second interval between the waterproof pan 10 and the end beam 4 are the same.
[0051]
As a result, the first interval, the second interval, and the interval (third interval) between the waterproof pan 10 and the girder 5 are the same, and after that, both of these width dimensions are W1. Work to construct the first to third draining members 21 to 23 that are commonly used, and to construct the fourth draining member 24 in the interval between the waterproof pan 10 and the outer surface member 1A of the building 1 .
[0052]
According to this embodiment described above, even if the basic module about the distance L1 between the pillars 1A of the building 1 to which the balconi 2 is attached and supported and the basic module about the dimension L2 of the waterproof pan 10 are not related, The first interval between the end beam 3 on the left side of the floor 2A of the balcony 2 and the waterproof pan 10, and the end beam 4 and the waterproof pan 10 on the right side outer profile member Therefore, the first draining member 21 and the second draining member 22 arranged at these locations can be shared as having the same width dimension W1, and each of the balconi construction sites can be used. Therefore, since it is sufficient to prepare draining members having various W1 dimensions based on the combination of L1 and L2, the types of draining members that must be prepared can be reduced.
[0053]
Moreover, since the 3rd space | interval between the waterproof pan 10 and the beam 5 is also the same W1 as a 1st space | interval and a 2nd space | interval, the 3rd draining member 23 arrange | positioned in the location of this 3rd space | interval is also shared. it can.
[0054]
And although the 4th draining member 24 arrange | positioned between the outer surface member 1A of the building 1 and the waterproofing pan 10 is not made common because the width dimension is W2, in this 4th draining member 24, Since the step portion 24D for forming a recess for filling the sealing material 30 with the outer surface member 1A is formed, the sealing material 30 allows watertightness between the fourth draining member 24 and the outer surface member 1A. Can be secured.
[0055]
Further, according to the present embodiment, the waterproof pan 10 placed on the joist 8 and disposed inside the floor 2A of the balcony 2 is provided between the outer surface member 1A and the girder 5 by the front and rear fixing members 11 and 12. Since the arrangement position between the left and right end beams 3 and 4 can be changed, the movement of the waterproof pan 10 in the left-right direction causes the first interval and the second interval to be changed. The operation | work which makes the space | interval the same can be performed easily.
[0056]
Furthermore, when the waterproof pan 10 is moved in the left-right direction so that the first interval and the second interval are the same, the waterproof pan 10 is slidable with respect to the front and rear fixing members 11, 12. The waterproof pan 10 can be accurately moved only in the left-right direction using the fixing members 11 and 12 as guide members, thereby facilitating this work.
[0057]
Furthermore, when performing this operation, the third interval is the same as the first interval and the second interval by the fixing members 11 and 12, and when the operation to make the first interval and the second interval the same is finished, Since these three intervals are the same, the work of arranging the waterproof pan 10 at a predetermined position on the floor 2A can be performed efficiently.
[0058]
In the embodiment described above, L1 and L2 are dimensions based on different basic modules, but the present invention can also be applied to cases where L1 and L2 are dimensions based on the same basic module.
[0059]
