【発明の属する技術分野】
本発明は、壁体貫通孔の充填用治具及び充填方法に関し、より詳しくは、建築物の壁体に形成された貫通孔の一方の開口部に該貫通孔の外側から蓋を設けづらい場合でも容易かつ速やかにその貫通孔にモルタルを充填することができ、また、モルタル導入時に貫通孔からモルタルが漏れ出すのを抑えることができ、更に、貫通孔内を完全に充填することができる壁体貫通孔の充填用治具及び充填方法に関する。
【０００２】
【従来の技術】
建築物の壁体に、壁体施工時或いは施工後に形成された貫通孔が有る場合、この貫通孔をモルタル等で充填する作業が行われる。従来は、この貫通孔を充填するに当たり、貫通孔の一端に蓋を設け、貫通孔の他端からモルタルを導入し、モルタルが貫通孔内に略充填された時点で貫通孔の他端に蓋を設けて、上記貫通孔内を充填していた。
しかしながら、壁体の片面が他の構造物と近接している等の理由でその片面に蓋を設けにくい場合には、上記した充填方法を採用することは困難であった。
また、貫通孔の上記他端に蓋が無い状態でモルタル導入作業を行うので、その作業中にモルタルが貫通孔から大量に漏れ出し、モルタルが無駄になってしまうとともに、貫通孔内を完全には充填することができなかった。
【０００３】
【発明が解決しようとする課題】
本発明は、このような実情に鑑みてなされたもので、建築物の壁体に形成された貫通孔の一端に該貫通孔の外側から蓋を設けづらい場合でも容易かつ速やかにその貫通孔にモルタルを充填することができ、また、モルタル導入時に貫通孔からモルタルが漏れ出すのを抑えることができ、更に、貫通孔内を完全に充填することができる壁体貫通孔の充填用治具及び充填方法の提供を目的とする。

【００１０】
【発明の実施の形態】
本発明の実施形態について、図面を参照しつつ説明する。
図１は、本発明に係る壁体貫通孔の充填用治具の第１実施形態を示す軸長方向断面図である。図２は、本発明における閉塞駒を示す図である。図３は、本発明における蓋体を示す図である。
【００１１】
第１実施形態に係る壁体貫通孔の充填用治具（１）は、壁体貫通孔（２）（図４参照）の一端開口部（２ａ）を閉塞するための閉塞駒（３）と、この閉塞駒（３）から延出する螺杆（８）と着脱自在に連結される操作棒（４）と、閉塞駒（３）から延出する螺杆（８）と着脱自在に連結され、壁体貫通孔（２）の他端開口部（２ｂ）を閉塞するための蓋体（５）とからなる。
【００１２】
閉塞駒（３）には円筒形状の弾性体（６）が備えられている。この弾性体（６）にはその中心軸に沿って貫通孔（７）が形成され、この貫通孔（７）には壁体貫通孔（２）と略同じ長さを有する螺杆（８）が挿通されている。弾性体（６）の種類は特に限定されるものではないが、例えば、合成ゴムを用いることができる。
螺杆（８）の長さは、閉塞駒（３）を壁体貫通孔（２）の一端開口部（２ａ）に固定したときに該螺杆（８）の基端部（９）が壁体貫通孔（２）の他端開口部（２ｂ）から突出しない程度の長さであることが好ましい。このような長さとすることで、壁体貫通孔（２）の充填後に螺杆（８）の基端部（９）が壁体貫通孔（２）から突出しない。
【００１３】
螺杆（８）の先端部には弾性体（６）の先端面と当接する受板（１０）が設けられている。螺杆（８）の中途部には弾性体（６）の基端面に当接するワッシャ（１１）が遊嵌されている。螺杆（８）の中途部においてワッシャ（１１）より基端部（９）側にはワッシャ（１１）と隣接したナット（１２）が進退可能に螺合されている。
螺杆（８）と受板（１０）は一体に構成されていてもよいが、別体に構成されていてもよい。別体に構成する場合、図示例の如く、螺杆（８）の先端に笠状の抜け止め部（１３）を形成し、この抜け止め部（１３）の基端面が受板（１０）に対し回転自在に当接するように構成することができる。
【００１４】
螺杆（８）の基端部（９）には第１の雄ネジ（１４）が設けられ、基端部（９）の第１の雄ネジ（１４）からワッシャ（１１）までの間には第１の雄ネジ（１４）と逆向きの第２の雄ネジ（１５）が設けられている。この第２の雄ネジ（１５）は、少なくとも螺杆（８）のワッシャ（１１）近傍に設けられる。また、第２の雄ネジ（１５）は、弾性体（６）を自然長から所定長さ縮ませるためにナット（１２）を螺進させるとともに、弾性体（６）を自然長に戻すためにナット（１２）を螺退させる。
基端部（９）に設ける第１の雄ネジ（１４）は、左ネジ或いは右ネジのいずれであってもよいが、図示例では左ネジが設けられており、これに応じて、第２の雄ネジ（１５）は、右ネジとされている。
【００１５】
操作棒（４）は、中空の筒体（１６）と、この筒体（１６）に挿通される棒体（１７）とからなる。
筒体（１６）の先端には、閉塞駒（３）のナット（１２）と嵌合するナット廻し部（１８）が形成されている。棒体（１７）の先端には、閉塞駒（３）の螺杆基端部（９）と螺合する雌ネジ（２７）が形成されている。
筒体（１６）の基端部には、ハンドル（２９）が設けられている。棒体（１７）の基端部には、把手（３０）が設けられている。
【００１６】
蓋体（５）は、螺杆基端部（９）と螺合する雌ネジ（２８）と、充填材導入孔（１９）と、を具備する。また、蓋体（５）は、壁体貫通孔（２）の他端開口部（２ｂ）を塞ぐ大きさに形成されている。
【００１７】
尚、蓋体（５）は、図示例の如く以下の構成を採ることが好ましい。
この例では、蓋体（５）は、本体（２０）と、パッキン（２１）とからなる。
本体（２０）は、壁面に対向する面側の中央部に円筒状突出部（２２）を有するとともに、該突出部（２２）の円筒孔内周面に螺杆基端部（９）と螺合可能な雌ネジ（２８）を有している。
パッキン（２１）は、本体（２０）の円筒状突出部（２２）に回転可能に外嵌する円筒状貫通孔（３１）を中央部に有している。
【００１８】
蓋体（５）及びパッキン（２１）にはそれぞれ、互いに重合一致させたときに充填材導入孔（１９）を構成する第１の孔部（２３）と、互いに重合一致させたときに充填材放出孔（２５）を構成する第２の孔部（２４）とが形成されている。第１の孔部（２３），（２３）同士の重合一致と第２の孔部（２４），（２４）同士の重合一致は同期するように構成されている。
【００１９】
次に、この充填用治具（１）を用いた壁体貫通孔（２）の充填方法について、図４乃至１２を参照しつつ説明する。
まず、図４に示す如く、操作棒（４）の筒体（１６）先端のナット廻し部（１８）を閉塞駒（３）のナット（１２）に嵌合させるとともに棒体（１７）先端の雌ネジ（２７）を螺杆基端部（９）と螺合させる。次いで、この操作棒（４）を介して壁体貫通孔（２）の他端開口部（２ｂ）から閉塞駒（３）を挿入し、壁体貫通孔（２）の一端開口部（２ａ）に閉塞駒（３）を到達させる（図５参照）。
【００２０】
ハンドル（２９）を回して筒体（１６）を回転させることにより、閉塞駒（３）の弾性体（６）を径方向に膨出させて壁体貫通孔（２）の一端開口部（２ａ）を閉塞する。すなわち、筒体（１６）を回転させることによりナット（１２）を螺進させ、弾性体（６）を自然長から所定長さ縮ませる。これにより、弾性体（６）がその径方向に膨出する。
その後、図６に示す如く、操作棒（４）を閉塞駒（３）から離脱させる。このとき、棒体（１７）（図５参照）を回転させて螺杆（８）と棒体（１７）との螺合を解除し、筒体（１６）を引っ張って筒体（１６）とナット（１２）の嵌合を解除する。これにより、操作棒（４）を壁体貫通孔（２）から抜き去ることができる。
【００２１】
図７に示す如く、壁体貫通孔（２）の他端開口部（２ｂ）において、螺杆基端部（９）に蓋体（５）の雌ネジ（２８）を螺合させて壁体貫通孔（２）の他端開口部（２ｂ）を閉塞する。このとき、蓋体（５）の周縁部を他端開口部（２ｂ）周辺の壁面に密着させる。
【００２２】
図８に示す如く、蓋体（５）の充填材導入孔（１９）からモルタル等の充填材（２６）を導入して壁体貫通孔（２）内を充填する。
充填が済んだら、図１０に示す如く、充填材導入孔（１９）を閉口手段（３２）（後で詳述）によって閉口し、充填材（２６）が固化するのを待つ。
充填材（２６）の固化後、図１１に示す如く、蓋体（５）を螺杆基端部（９）から離脱させる。このとき、蓋体（５）（図１０参照）を回転させて蓋体（５）と螺杆（８）の螺合を解除する。
【００２３】
蓋体（５）を取り外した後は、図１２に示す如く、壁体貫通孔（２）の一端開口部（２ａ）において、閉塞駒（３）の外側にモルタル等の充填材（２６）を埋め込んでその充填材（２６）の表面を一端開口部（２ａ）周囲の壁面とを面一にする。また、壁体貫通孔（２）の他端開口部（２ｂ）において、既に固化している充填材（２６）の窪みに更に充填材（２６）を埋め込み、新たに埋め込んだ充填材（２６）の表面を他端開口部（２ｂ）周囲の壁面と面一にする。
【００２４】
尚、蓋体（５）が、上記した如く、本体（２０）とパッキン（２１）とからなる場合には、蓋体（５）を設ける際、図７に示す如く、本体（２０）とパッキン（２１）の第１の孔部（２３）同士を重合一致させると共に第２の孔部（２４）同士を重合一致させた状態で、壁体貫通孔（２）の他端開口部（２ｂ）を閉塞し、重合一致した第１の孔部（２３）を充填材導入孔（１９）としてここから充填材（２６）を導入する。
充填材（２６）が壁体貫通孔（２）内で満杯になった後に更に導入を続けると、図９に示す如く、重合一致した第２の貫通孔（２４）すなわち充填材放出孔（２５）から充填材（２６）の一部が溢れ出るので、この時点で充填材（２６）の導入をストップする。
【００２５】
充填材（２６）の導入をストップした直後に、蓋体（５）のパッキン（２１）を本体（２０）に対して回転させ、第１の孔部（２３）同士の位置をずらす（図１０参照）とともに第２の孔部（２４）同士の位置をずらし、充填材導入孔（１９）及び充填材放出孔（２５）を閉じる（閉口手段）。これにより、充填材（２６）の漏出が防止される。
尚、閉口手段は上記した例に限定されず、ガムテープ等を用いて閉口してもよい。
以上により、壁体貫通孔（２）の充填作業を終了する。
【００２６】
本発明に係る壁体貫通孔の充填用治具（１）及び充填方法によれば、建築物の壁体貫通孔（２）の一方の開口部にその外側から蓋を設けづらい場合でも容易かつ速やかにその壁体貫通孔（２）にモルタル等の充填材（２６）を充填することができる。また、充填作業中に壁体貫通孔（２）から充填材（２６）が漏れ出すのを抑えることができ、更に、壁体貫通孔（２）内を完全に充填することができる。
【００２７】
次に、本発明の第２実施形態について説明する。
図１３は、第２実施形態に係る充填用治具を示す軸長方向断面図である。
第２実施形態に係る充填用治具（１）が上記第１実施形態と異なる点は幾つかある。その他の構成ついては、上記第１実施形態と同様とすることができる。
先ず、螺杆（８）の長さが、壁体貫通孔（２）の長さよりも長く設定されている。これは、様々な厚みの壁体に対応するためである。尚、後述するように、モルタル充填後に、螺杆（８）の壁面外に突出している部分は切断除去される。
尚、第１実施形態と同様、螺杆（８）の基端部（９）には第１の雄ネジ（１４）が設けられ、第１の雄ネジ（１４）からワッシャ（１１）までの間には第１の雄ネジ（１４）と逆向きの第２の雄ネジ（１５）が設けられている。
【００２８】
蓋体（５）は、螺杆（８）の基端部（９）側部分を挿通させる螺杆挿通孔（３３）と、充填材導入孔（１９）とを具備している。この螺杆挿通孔（３３）を通じて、螺杆（８）の基端部（９）側部分が壁面外へ突き出される。
螺杆挿通孔（３３）は、螺杆（８）挿通状態において螺杆（８）の第２の雄ネジ（１５）周面に固定される。その固定手段は特に限定されるものではないが、例えば、螺杆挿通孔（３３）の内周面に、螺杆（８）の第２の雄ネジ（１５）と螺合する雌ネジ（３４）を形成し、この雌ネジ（３４）と第２の雄ネジ（１５）を螺合することにより、螺杆（８）に蓋体（５）を固定することができる。
【００２９】
尚、蓋体（５）は、図１４に例示する如く以下の構成を採ることが好ましい。
この例では、蓋体（５）は、本体（２０）と、パッキン（２１）とからなる。
本体（２０）は、壁面に対向する面側の中央部に円筒状突出部（２２）を有している。この円筒状突出部（２２）には、本体（２０）を貫通する螺杆挿通孔（３３）が形成されており、この螺杆挿通孔（３３）内周面に、第２の雄ネジ（１５）と螺合可能な雌ネジ（３４）が設けられている。
パッキン（２１）は、本体（２０）の円筒状突出部（２２）に回転可能に外嵌する円筒状貫通孔（３１）を中央部に有している。円筒状突出部（２２）の突出長は、例えば、パッキン（２１）の円筒状貫通孔（３１）の長さと略同じに設定することができる。
【００３０】
また、本体（２０）及びパッキン（２１）にはそれぞれ、互いに重合一致させたときに充填材導入孔（１９）を構成する第１の孔部（２３）と、互いに重合一致させたときに充填材放出孔（２５）を構成する第２の孔部（２４）とが形成され、第１の孔部（２３）同士の重合一致と第２の孔部（２４）同士の重合一致が同期するように構成されていることが好ましい。

次に、第２実施形態に係る充填用治具（１）を用いた、壁体貫通孔（２）の充填方法を、図１５乃至２３を参照しつつ説明する。
まず、図１５に示す如く、操作棒（４）の筒体（１６）先端のナット廻し部（１８）を閉塞駒（３）のナット（１２）に嵌合させるとともに棒体（１７）先端の雌ネジ（２７）を螺杆基端部（９）と螺合させる。次いで、この操作棒（４）を介して壁体貫通孔（２）の他端開口部（２ｂ）から閉塞駒（３）を挿入し、壁体貫通孔（２）の一端開口部（２ａ）に閉塞駒（３）を到達させる（図１６参照）。
一端開口部（２ａ）に閉塞駒（３）を到達させたとき、螺杆（８）の基端部（９）側部分は幾分、貫通孔（２）から突出している。
【００３２】
ハンドル（２９）を回して筒体（１６）を回転させることにより、閉塞駒（３）の弾性体（６）を径方向に膨出させて壁体貫通孔（２）の一端開口部（２ａ）を閉塞する。すなわち、筒体（１６）を回転させることによりナット（１２）を螺進させ、弾性体（６）を自然長から所定長さ縮ませる。これにより、弾性体（６）がその径方向に膨出する。
その後、図１７に示す如く、操作棒（４）を閉塞駒（３）から離脱させる。このとき、棒体（１７）（図１６参照）を回転させて螺杆（８）と棒体（１７）との螺合を解除し、筒体（１６）を引っ張って筒体（１６）とナット（１２）の嵌合を解除する。これにより、操作棒（４）を壁体貫通孔（２）から抜き去ることができる。
【００３３】
図１８に示す如く、壁体貫通孔（２）の他端開口部（２ｂ）において、螺杆（８）の基端部（９）側部分を蓋体（５）の螺杆挿通孔（３３）に挿通し、蓋体（５）を螺杆（８）の基端部（９）側部分に固定させて、壁体貫通孔（２）の他端開口部（２ｂ）を閉塞する。このとき、蓋体（５）の周縁部を他端開口部（２ｂ）周辺の壁面に密着させる。
尚、螺杆挿通孔（３３）に雌ネジ（３４）が形成されている場合は、この雌ネジ（３４）を螺杆（８）の第２の雄ネジ（１５）に螺合させることで、蓋体（５）を螺杆（８）の基端部（９）側部分に固定する。
【００３４】
図１９、２０に示す如く、蓋体（５）の充填材導入孔（１９）からモルタル等の充填材（２６）を導入して壁体貫通孔（２）内を充填する。尚、図示例では、充填材導入孔（１９）が蓋体（５）の上部に位置しているが、下部に位置させてもよい。
充填が済んだら、図２１に示す如く、充填材導入孔（１９）を閉口し、充填材（２６）が固化するのを待つ。
充填材（２６）の固化後、図２２に示す如く、蓋体（５）を螺杆基端部（９）から離脱させる。
【００３５】
蓋体（５）を取り外した後は、図２３に示す如く、壁体貫通孔（２）の一端開口部（２ａ）において、閉塞駒（３）の外側にモルタル等の充填材（２６）を埋め込んでその充填材（２６）の表面を一端開口部（２ａ）周囲の壁面とを面一にする。また、壁体貫通孔（２）の他端開口部（２ｂ）において、螺杆（８）の壁面外突出部（３６）（図２２参照）を切断除去する。そして、固化した充填材（２６）の表面をグラインダ等を用いて平らに仕上げ、充填材（２６）の表面を他端開口部（２ｂ）周囲の壁面と面一にする。
以上により、壁体貫通孔（２）の充填作業を終了する。
【００３６】
この第２実施形態においても、第１実施形態と同様の効果を奏することができる。また、様々な厚みの壁に対応した充填作業を行うことができる。
【００３７】
【発明の効果】
請求項１及び２記載の発明によれば、建築物の壁体貫通孔の一方の開口部にその外側から蓋を設けづらい場合でも容易かつ速やかにその壁体貫通孔にモルタル等の充填材を充填することができる。また、充填作業中に壁体貫通孔から充填材が漏れ出すのを抑えることができ、更に、壁体貫通孔内を完全に充填することができる。
【００３８】
請求項３及び４記載の発明によれば、充填材の導入をストップした直後に、蓋体のパッキンを本体に対して回転させ、第１の孔部同士の位置をずらすとともに第２の孔部同士の位置をずらし、充填材導入孔及び充填材放出孔を閉じることにより、充填材の漏出を容易かつ速やかに防止することができる。また、充填材放出孔から充填材の一部が溢れ出ることにより、壁体貫通孔内で満杯になったことが明確に判るので、充填材の導入をストップするタイミングを正確に把握することができる。
