以上のごとく，本発明によれば，外観意匠性及び防水性に優れた開口部周り施工構造の構築を容易に実現させることができるＬ型ガイド部材を提供することができる。
【００２０】
【発明の実施の形態】
上記第１の発明（請求項１）において，上記開口部周り化粧部材の前板部の意匠面と上記窯業系外壁板の意匠面とは，略同一平面上にあることが好ましい。この場合には，上記開口部周り化粧部材が窯業系外壁板に一層外観上融合し，より外観意匠性に優れた開口部周り施工構造を得ることができる。
また，上記開口部周り施工構造は，リフォーム用であってもよく，また新築用であってもよい。
【００２１】
また，上記Ｌ型ガイド部材は，上記前方ガイド部及び下方ガイド部を，例えば，ガルタイト鋼板，ガルバリウム鋼板，その他の表面処理鋼板，或いはステンレス鋼板等により構成し，上記弾性部材をＥＰＤＭ発泡体，シリコーンゴム発泡体，合成ゴム発泡体等とすることができる。
また，上記窯業系外壁板及び開口部周り化粧部材の，下地材への固定方法としては，例えば，留め付け金具による留め付け，あるいは釘打ち固定等がある。

【００２２】
また，上記上方開口部周り化粧部材は，上記折返し板部の裏側面と上記前板部の裏側面とのなす角度が略直角であり，上記Ｌ型ガイド部材は，上記前方ガイド部と上記下方ガイド部とのなす角度が鈍角であることが好ましい（請求項２，請求項７）。
この場合には，上記下方ガイド部が傾斜した状態で，上記Ｌ型ガイド部材が取り付けられるため，下方ガイド部に落下した結露水が後方へ流れやすくなる。それ故，結露水の排出を効率的に行うことができる。また，上記上方開口部周り化粧部材の裏側面に，上記Ｌ型ガイド部材の２つの弾性部材を確実に密着させることができる。
【００２３】
また，上記前方ガイド部と下方ガイド部とのなす角度は，９５〜１２０°であることが好ましい。これにより，上記の効果をより一層確実に発揮することができる。上記角度が９５°未満の場合には，上記結露水を効率的に排出することが困難となるおそれがあると共に，弾性部材を上方開口部周り化粧部材の裏側面に確実に密着させることが困難となるおそれがある。一方，上記角度が１２０°を超える場合には，下地材と上方開口部周り化粧部材との間に上記Ｌ型ガイド部材を配設することが困難となるおそれがある。
【００２４】
また，上記上方開口部周り化粧部材の折返し板部の後端には，鉛直方向に貫通する水抜き穴を有する水抜き部材を配設してなることが好ましい（請求項３，請求項８）。
この場合には，上記上方開口部周り化粧部材の上のＬ型ガイド部材に落下した結露水を，上記水抜き部材を介して排出することができる。
【００２５】
また，上記開口部の下辺には，その下側に配される窯業系外壁板の上辺部を上方及び前方から覆う水切板が配設されていることが好ましい（請求項４，請求項９）。
この場合には，上記開口部の下辺における窯業系外壁板に，その上辺部から雨水が浸透することを防止すると共に，外観意匠性を向上させることができる。
【００２６】
また，上記開口部周り化粧部材と上記下地材との間には，略鉛直方向に貫通した通気穴を有するスペーサが介在していることが好ましい（請求項５）。
この場合には，上記開口部周り化粧部材と下地材との間に通気層を形成して，開口部周り化粧部材の後方の通気性を確保することができる。
【００２７】
次に，上記第２の発明（請求項６）において，上記下地材配設工程の後，上記化粧部材配設工程の前には，略鉛直方向に貫通した通気穴を有するスペーサを，上記下地材の前面に配設し，該スペーサの前面から，上記開口部周り化粧部材を上記下地材に固定することが好ましい（請求項１０）。
この場合には，上記開口部周り化粧部材と下地材との間に通気層を形成して，開口部周り化粧部材の後方の通気性を確保した，開口部周り施工構造を構築することができる。
【００２８】
次に，上記第３の発明（請求項１１）において，上記前方ガイド部と上記下方ガイド部とのなす角度は鈍角であることが好ましい（請求項１２）。
この場合には，上記下方ガイド部が傾斜した状態で，上記Ｌ型ガイド部材を取り付けることができるため，下方ガイド部に落下した結露水が後方へ流れやすくなる。それ故，結露水の排出を効率的に行うことができる。また，上記上方開口部周り化粧部材の裏側面に，上記Ｌ型ガイド部材の２つの弾性部材を確実に密着させることができる。
また，上記前方ガイド部と下方ガイド部とのなす角度は，９５〜１２０°であることが好ましい。

また，上記前方ガイド部５１と下方ガイド部５２とのなす角度が約１００°であることにより，上記の効果をより一層確実に発揮することができる。
【００５６】
また，図１，図４に示すごとく，上記上方開口部周り化粧部材３０の折返し板部３２の後端３２１に，上記水抜き部材６を配設してあるため，上記上方開口部周り化粧部材３０の上のＬ型ガイド部材５に落下した結露水を，上記水抜き部材６を介して排出することができる。
【００５７】
また，図２に示すごとく，上記開口部４２の下辺には，上記水切板７が配設されているため，上記開口部４２の下辺に配された窯業系外壁板２に，その上辺部（切欠部２３の上辺部）から雨水が浸透することを防止すると共に，外観意匠性を向上させることができる。
【００５８】
また，上記開口部周り化粧部材３と上記下地材１１との間には，上記スペーサ１３，１３０が介在しているため，上記開口部周り化粧部材３と下地材１１との間に通気層１６を形成して，開口部周り化粧部材３の後方の通気性を確保することができる。
【００５９】
以上のごとく，本例によれば，外観意匠性及び防水性に優れた開口部周り施工構造及び開口部周り施工方法を提供することができる。
【００６０】
（実施例２）
本例は，図１８に示すごとく，既存壁４１の厚みが比較的薄く，窓サッシ４３までの奥行きが比較的小さい場合の例である。
かかる場合には，開口部周り化粧部材３の折返し板部３２の前後長さを小さくする必要があり，これに合わせて，Ｌ型ガイド部材５の下方ガイド部５２を短くする必要がある。
【００６１】
この場合，上記Ｌ型ガイド部材５を，上記折返し板部３２の長さに対応して，それぞれ作製してもよい。また，上記Ｌ型ガイド部材５の前方ガイド部５１と下方ガイド部５２との長さを予め異ならせておいて，適宜，前方ガイド部５１と下方ガイド部５２とを逆にして使用することもできる。これにより，一種類のＬ型ガイド部材５を作製しておくだけで，既存壁４１の厚み，開口部周り化粧部材３の折返し板部３２の長さが種々変化しても，Ｌ型ガイド部材５の配置方法を変えるだけで対応することができる。
その他は，実施例１と同様であり，同様の作用効果を有する。
