【００１４】
【発明の実施の形態】
以下図面を参照しながら、本発明に係る防水工法及び防水構造の好ましい実施形態を説明する。
第１実施形態
図１は本発明に係る実施形態の防水工法及び防水構造を陸棟に実施した施工構造の部分断面図、図２は棟に沿って取り付けられた芯材の部分拡大側断面図、図３（ａ）図は図１の施工構造で使用されている保持体の部分分解斜視図、同（ｂ）図は保持体における板状本体の他の形態を示す部分斜視図、図４は芯材のフランジに保持体を取り付けた状態の部分側面図である。
【００１５】
先ず、面戸部の上面輪郭部を形成し陸棟の芯体を構成する各芯材１の張り出し部であるフランジ１１の下面に保持体３を吊り下げ状に取り付け、これら芯材１を、取付具２を使用して陸棟の屋根下地９０に取り付ける。棟の両側の流れ面には、既に桟木９１等に桟瓦９が釘止めされた状態で葺かれている。
芯材１は角柱状の芯本体１０とその両側部に長さ方向に沿って一体に形成されたフランジ１１とから構成されている。芯本体１０の下面には長さ方向に沿って溝１２が形成され、溝１２の内底と本体１０の上面には小溝１４，１５が形成され、フランジ１１の下面には蟻溝状の取付溝１３が形成されている。
芯材１は、乾燥した木材チップを微細に粉砕した木材パウダーをプラスチックと配合して一体成形した、いわゆる木質材料によって構成されている。この実施形態では、芯材１のプラスチック材料として再生ポリスチレンを用いている。
芯材１の長さは、後述の熨斗瓦５の長さや施工の作業性等を考慮して設計されるが、この実施形態では２０００ｍｍ程度に設計されている。
【００１６】
保持体３は、取付状態において下方の桟瓦９の上面形状に適合して変形するような柔軟性を有する部材である。この実施形態では、図３の（ａ）図のように、例えば発泡ウレタンやゴムスポンジその他の柔軟材料からなる板状本体３０と、板状本体３０の一方の長辺部に沿って固定された塩化ビニール等の硬質のプラスチックからなる縁材３１とから構成されている。
板状本体３０は、縁材３１が固定されている側を背として多数の歯状片３０ａが形成されて全体が櫛形状を呈している。
板状本体３０は縁材３１には下面に長さ方向に沿って形成された溝３１ａヘ接着され、縁材３１の幅は板状本体３０の肉厚よりもやや広いため、縁材３１の両側部は長さ方向に沿うフランジ状になっている。この縁材３１を芯材１におけるフランジ１１の取付溝１３に差し込むことにより、保持体３を前記フランジ１１ヘ垂れ下げ状に取り付けるように構成している。
【００１７】
各取付具２は、中央部に下向きの溝状部２０ａを有する金属板からなる取付ベース２０と、溝状部２０ａに上下方向へ貫通状に固定された．スリーブ状のナット２１ａとボルト２１ｂからなる伸縮調整可能なシャフト２１と、当該シャフト２１の上端部へ水平に取り付けた角パイプからなるの支承部材２２とから構成されている。取付ベース２０の溝状部２０ａ以外の部分には、複数のねじ孔が形成されている。
取付具２は、両側の取付ベース２０を棟部の屋根下地９０の傾斜に合わせ、当該取付ベース２０を屋根下地９０ヘねじ止めすることにより、図２のように芯材１の長さに合わせた間隔で取り付けられる
図２で示すように、取付具２は芯材１の端部と芯材１相互の連結部と対応する位置に取り付けら、シャフト２１のボルト２１ｂをねじ回して支承部材２２のレベルを調整した後、芯材１の溝１２と支承部材２２とを合わせて芯材１の端部を支持させる。
【００１８】
支承部材２２の天板には中央部の孔２３と両端寄りの孔２４，２４とが形成され、棟の端部においては、Ｌ字状の主部２６ａと主部２６ａの上端部の一方に一体的に曲げ加工された押え板．２６ｂとを有する固定金具２６を使用する。支承部材２２に芯材１の端部を固定するには、金具２６の主部２６ａと押え板２６ｂとで芯材１の端部を挟む要領で先端のフック部２６ｃを支承部材２２の孔２４に引掛け、押え板２６ｂを芯材１の上部の溝１５へ案内し、当該押え板２６ｂを芯材１にねじ釘２７で止める。
芯材１相互の連結部においては、先端部にフック部２５ｃを有するＬ字状の主部２５ａの上端部両側方に押え板２５ｂ，２５ｂを有する固定金具２５を使用する。支承部材２２へ芯材１，１相互の端部を固定し、芯材１，１相互を連結するには、金具２５の主部２５ａの下端を支承部材２２の中央の孔２３に通してフック部２５ｃを一つの孔２４に引掛け、主部２５ａの両面に芯材１，１相互の端部を当接させ、一方の芯材１の端部を主部２５ａと一方の押え板２５ｂとで挟む要領で各押え板２５ｂをそれぞれの芯材１の溝１５に案内し、当該各押え板２５ｂを対応する芯材１へねじ釘２７で止める。
【００１９】
保持体３の板状本体３０は柔軟性があるので、図４のように多数の歯状片３０ａは下方の桟瓦９の上面の凹凸に適合変形して接触する。この状態で、例えば吹付けガンなどにより保持体３に発泡性のプラスチック（この実施形態ではウレタン）を吹き付けて発泡させ、これを保持体３の板状本体３０に万遍なく塗り付けるようにして保持させ固化させ、閉塞部４を形成する。この閉塞部４により、面戸部の上部輪を形成する張り出し部である芯材１のフランジ１１と桟瓦９との隙間を塞ぐ。発泡性のプラスチック材は、吹付けにより発泡膨張した後間もなく固まり始めやがて壁状の閉塞部４になる。
次いで、フランジ１１の上に面戸瓦５の上端部をねじ５ａにより固定し、閉塞部４の外側を当該面戸瓦５で塞いで仕上げる。
【００２０】
後は通常の乾式瓦屋根の棟組み工法と同様に、左右一体型の大型の熨斗瓦６と小型の熨斗瓦６０とを芯材１の上に適当層重ね積みし、最上部の熨斗瓦の６０の上に沿って押え材７を置き、押え材７と芯材１とをステンレス製のねじ釘７０で締め付けることにより、各熨斗瓦６，６０を芯材１へ固定する。６ａ，６０ａは、それぞれの熨斗瓦６，６０に所定の間隔に形成されているねじ通し孔である。
さらに、最上段の熨斗瓦６０の上に冠瓦８を被せ、この冠瓦８を頭部にパッキンを有するねじ釘８０により押え材７に固定する。
前記施工の際上下の熨斗瓦６，６０相互は、長さ方向に並べた相互の接触部が交互に位置するように重ねられる。
前記の施工の際には、面戸瓦５の上面と最下段の熨斗瓦６との間に長さ方向に沿って枕状に生モルタルを介在させることができる。この際には、芯材１における本体１０の上下方向の厚みを厚くする。
【００２１】
前記実施形態の防水工法及び防水構造によれば、柔軟性を有する保持体３が桟瓦９の上面形状に適合して良く変形して桟瓦９の上の面戸部に納まり、これに発泡性プラスチックを発泡状態で吹き付けるので、プラスチック材が固まった閉塞部４により面戸部分がほぼ隙間なく塞がれる。また、防水性も従来技術と比べはるかに向上する。
さらに、面戸部分の防水施工がより簡単かつ迅速に行われる。
【００２２】
第２実施形態
図５は本発明に係る実施形態の防水工法及び防水構造を隅棟に実施した棟構造の断面図である。
隅棟の両側の流れには、屋根下地９０に桟瓦９がねじ釘などにより固定状態で葺かれており、隅棟に沿う部分には芯材１が第１実施形態と同様な要領により固定されている。
芯材１は、第１実施形態の芯材とは、面戸部の上面輪郭を形成する張り出し部であるフランジ１１の形状を若干異にしており、フランジ１１の上面は傾斜面ではなく水平面となっており、当該上面には長さ方向に沿って溝又は突条１１ａが形成されている。．
この実施形態では、芯材１を隅棟に取り付けた状態では、フランジ１１と下の桟瓦９との間が大きくなっているので、芯材１を屋根下地９０に固定した後、保持体３をフランジに取り付けることができる。
【００２３】
第１実施形態とほぼ同様に、保持体３に発泡性のプラスチック４を吹き付けて発泡保持させ、この部分に閉塞部４を形成してフランジ１１と桟瓦９との隙間である面戸部を防水施工する。閉塞部４が固まった後、当該閉塞部４の外側から前記フランジ１１の上面にわたる部分に生モルタルにより化粧壁５０を塗工する。このとき、化粧壁５０が溝又は突条１１ａを覆う状態に塗工し、モルタルを溝又は突条１１ａへ絡ませて強固な塗工状態が得られるようにしている。
その後、第１実施形態とほぼ同様に芯材１の上に適数段の熨斗瓦６，６０を重ね積みするとともに、押え材７とねじ７０によりそれらを芯材１に固定し、その上部に冠瓦８を固定して隅棟の施工を完了する。
この実施形態の防水工法及び防水構造の他の構成や作用効果は、第１実施形態の防水工法とほぼ同様であるので、それらの説明は省略する。
【００２４】
第３実施形態
図６は本発明に係る実施形態の防水工法及び防水構造を水平壁際に実施した壁際構造の断面図である。
下屋根の屋根下地９０には、桟木９１にねじ止めされた状態で桟瓦９が葺かれている。
先ず、下屋根側に張り出したフランジ１１を有する芯材１の前記フランジ１１に保持体３を垂れ下げ状に取り付ける。芯材１は壁際部の芯体を構成するもので、外側端部を桟瓦９の上に張り出させて面戸部の上面輪郭を形成するフランジ１１を有する。この芯材１を、水平壁際に沿って垂れ壁９２に対しフランジ１１が下屋根上端の桟瓦９の上面からやや浮上した状態になるように連続して取付け固定する。保持体３の構成やフランジ１１に対する保持体３の取付要領は第１実施形態とほぼ同様である。
芯材１は第１実施形態の防水工法で使用した芯材とほぼ同様な材質であり、フランジ１１よりも上方部分には、適数の階段状の支承部１６が形成され、底部の壁際寄り位置には溝１７が形成され、背面側には後述の取付金具２ａが嵌め込み状に収容されるむように収容部１９が形成されている。
【００２５】
芯材１の垂れ壁９２への固定は、以下の要領で行う。
先ず垂れ壁９２へ所定の間隔に、かつレベルを揃えてＬ字状の取付金具２ａを複数のねじ釘２８で取り付ける。いくつかの取付金具２ａは、長さ方向に連続して並ぶ芯材１相互の接触部（継ぎ目部）に位置する状態にする。
取付金具２ａの先端には断面Ｕ字状の引掛け部２ｂが形成されており、この引掛け部２ｂが芯材１の溝１７へ収まる状態で芯材１を各取付金具２ａに支持させ、芯材１の上端部を所定の間隔で垂れ壁９２へねじ釘１８で止める。
【００２６】
芯材１を前述のように垂れ壁９２へ連続状態に固定すると、保持体３の板状本体３０はその柔軟性により桟瓦９の上面形状に適合して変形接触するので、これに対し発泡性のプラスチックを吹き付けて発泡保持させ、この部分に閉塞部４を形成し、芯材１のフランジ１１と桟瓦９の間の面戸部を塞いで防水施工する。その後、フランジ１１の上面ヘねじ釘５ａにより取り付けた面戸瓦５により、閉塞部４の外側を塞ぐ。
芯材１の各支承部１６にはそれぞれ熨斗瓦６１の片側を載置し、当該片側をねじ釘６１ａによりそれぞれの支承部１６に釘止めする。最上位の熨斗瓦６１の上の壁際には、捨て板９３を設置するとともに、当該捨て板９３を板金９４でカバーし、板金９４とともに捨て板９３を芯材１の上端縁にねじ止めし、さらに、板金９４を垂れ壁９２へねじ止めする。上方の垂れ壁９２には、化粧モルタル９５を塗工し、水平壁際を仕上げる。
第３実施形態の防水工法及び防水構造の他の構成や作用効果は、第１実施形態のそれとほぼ同様であるので、．それらの説明は省略する。
【００２７】
第４実施形態
図７は本発明に係る実施形態の防水工法及び防水構造を傾斜壁際に実施した壁際構造の断面図である。
下屋根には、屋根下地９０に桟瓦９がねじ釘などにより固定状態で葺かれており、下屋根の壁際には材１が第３実施形態と同様な要領により固定される。９０ａは捨て水切り板である。
芯材１は、第３実施形態の芯材とはフランジ１１の形状を若干異にしているがほぼ同様な形態であり、フランジ１１の先端部の上面には長さ方向に沿って溝又は突条１１ａが形成されている。．
この実施形態では、芯材１を垂れ壁９２に取り付けた状態では、フランジ１１と下の桟瓦９との間が大きくなっているので、芯材１を屋根下地９０に固定した後、保持体３をフランジ１１に取り付けることができる。
【００２８】
第２実施形態とほぼ同様に、保持体３に発泡状態のプラスチックを吹き付けて保持させ、当該プラスチックによりフランジ１１と桟瓦９との隙間を塞ぐ閉塞部４を形成する。閉塞部４を形成するプラスチック材が固まった後、閉塞部４の外側から前記フランジ１１の上面にわたる部分に生モルタルによる化粧壁５０を塗工する。このとき、化粧壁５０が溝又は突条１１ａを覆う状態に塗工し、モルタルを溝又は突条１１ａへ絡ませて強固な塗工状態が得られるようにしている。
この実施形態の防水工法及び防水構造の他の構成や作用効果は、第３実施形態とほぼ同様であるので、それらの説明は省略する。
【００２９】
その他の実施形態
保持体３の板状本体３０は、前述のように櫛状に形成するのに代えて、例えば図３の（ｂ）図のように、プラスチックやゴムを発泡させたスポンジの板に多数の孔３０ｂを形成したものでもよい。また、板状本体３０はプラスチック発泡体ではなく、フォームラバー，柔軟なプラスチックやゴム等の軟質材料を使用することができる。
さらに、保持体３は下端側が下方の桟瓦９の上面形状に適合して変形するような柔軟性を有していればよいので、前述のような材料のほかに、各種の紐やこれらの紐で編んだ網などを適宜選択して使用することができる。
【００３０】
