【発明の属する技術分野】
本発明はドアを改修する場合のドアの改修方法及びドアの改修構造に関するものである。
【０００２】
【従来の技術】
従来、ドアを改修する場合、扉体のみでなくドア枠も改修されている。ドア枠の改修では既存のドア枠を取壊し、新規にドア枠を設置する場合もあるが、工事が大掛りとなるので、既存のドア枠を利用して改修用のドア枠を取付けるドアの改修方法が実施されている。
【０００３】
図５、図６に於いて、従来のドアの改修方法及びドアの改修構造について説明する。
【０００４】
図５は左右の縦枠の断面を示す部分断面図、図６は上下枠の断面を示す部分断面図を示している。
【０００５】
図中、１は建屋等の躯体を示し、２は該躯体１に設けられた出入口等の開口部であり、又３は内部、４は外部を示している。
【０００６】
前記躯体１の前記開口部２の両側部には既存縦枠５，６が設けられ、前記躯体１の前記開口部２の上部には既存上枠１１、下部には既存下枠１２が設けられている。
【０００７】
前記既存縦枠５，６は対称な断面を有しており、該既存縦枠５，６の断面形状は外部分が低い段差部７となっている略Ｌ字形状をしており、該段差部７に既存の扉（図示せず）が嵌込む様になっている。既存の扉、蝶番（いずれも図示せず）を取外し、前記既存縦枠５と既存縦枠６に対して同様な改修が行われる。以下は前記既存縦枠５について説明する。
【０００８】
前記既存縦枠５の内部側角部に断面Ｌ字状の内側下地金具８が前記既存縦枠５の全長に亘り設けられ、螺子止される。又、前記段差部７には断面Ｌ字状の外側下地金具９が所定間隔で複数設けられ、それぞれ螺子止される。前記外側下地金具９は後述する改修用扉体１０の略厚み分だけ前記外部４側に突出している。
【０００９】
前記内側下地金具８と外側下地金具９に掛渡って改修用縦枠１３が設けられ、該改修用縦枠１３は前記既存縦枠５と略等しい長さを有している。前記改修用縦枠１３は、前記既存縦枠５と対峙する平面部１３ａ、及び該平面部１３ａに続き前記段差部７に相当する段差部１４、該段差部１４より前記外部４側に突出しコの字に折返されて縦枠部１３ｂが形成されている。
【００１０】
前記改修用縦枠１３の前記平面部１３ａの内側端部は前記内側下地金具８を介して前記既存縦枠５に螺子止により取付けられ、前記改修用縦枠１３の前記段差部１４の部分は前記外側下地金具９に螺子止されている。尚、前記躯体１の外面と前記改修用縦枠１３との隙間は充填剤１５により充填されている。
【００１１】
前記既存上枠１１に関する改修については、前記既存縦枠５，６と同様な方法及び構造で行われる。前記既存上枠１１は前記既存縦枠５と同等の断面形状を有し、前記既存上枠１１の内部側角部に断面Ｌ字状の内側下地金具１６が前記既存上枠１１の全長に亘り設けられ、螺子止される。又、段差部１７には断面Ｌ字状の外側下地金具１８が所定間隔で複数設けられ、それぞれ螺子止される。前記外側下地金具１８は後述する前記改修用扉体１０の略厚み分だけ前記外部４側に突出している。
【００１２】
前記内側下地金具１６、外側下地金具１８に掛渡って、改修用上枠１９が設けられ、該改修用上枠１９は前記既存上枠１１と略等しい長さを有している。
【００１３】
前記改修用上枠１９の平面部１９ａの内側端部は前記内側下地金具１６を介して前記既存上枠１１に螺子止により取付けられ、前記改修用上枠１９の段差部２１の部分は前記外側下地金具１８に螺子止されている。尚、前記躯体１の外面と前記改修用上枠１９との隙間は充填剤２２により充填されている。
【００１４】
前記既存下枠１２は前記既存上枠１１と略同様な断面形状を有し、下地金具２３は前記既存下枠１２の段差部２７に設けられる。前記下地金具２３は凹部２３ａと凸部２３ｂが連続して形成され、更に舌片２３ｃが前記外部４に延出した形状となっており、前記凹部２３ａが前記既存下枠１２に螺子止されている。
【００１５】
前記既存下枠１２と前記下地金具２３に掛渡り改修用下枠２４が設けられ、該改修用下枠２４は前記既存下枠１２と略同じ長さを有する。前記改修用下枠２４は前記段差部２１に対峙する段差部２５が形成された断面を有しており、前記既存下枠１２、前記凸部２３ｂに当接する平面部２４ａは折返された２枚重合わせとなっている。前記改修用下枠２４は前記凸部２３ｂに螺子止される。
【００１６】
前記改修用縦枠１３，１３、前記改修用上枠１９、前記改修用下枠２４により改修ドア枠が構成され、蝶番２６を介して前記改修用扉体１０が前記改修用縦枠１３に取付けられる。前記改修用扉体１０が閉じられた状態では、該改修用扉体１０は前記段差部１４、段差部２１、段差部２５により形成される枠状の段差部に収納される。
【００１７】
【発明が解決しようとする課題】
上記した従来のドアの改修方法及びドアの改修構造では、既存のドア枠に直接、或は下地金具を介して密着させて取付けるので、縦枠の垂直度、上枠、下枠の水平度が既存枠合せになる。この為、既存のドア枠に狂いが生じていた場合は、必要な精度が得られなくなる虞れがあった。
【００１８】
本発明は斯かる実情に鑑み、既存のドア枠に狂いが生じていた場合でも、より正確にドアの改修が行える様にするものである。
【００１９】
【課題を解決するための手段】
本発明は、一方の既存縦枠に一方の改修用縦枠を鉛直に調整して取付け、該一方の改修用縦枠を基準に所定の対角寸法を求め、その後対角寸法を基準に他方の改修用縦枠、改修用上枠、改修用下枠を他方の既存縦枠、既存上枠、既存下枠に取付けるドアの改修方法に係り、又一方の既存縦枠にスペーサを介して一方の改修用縦枠を鉛直に取付け、既存下枠にスペーサを介して改修用下枠を取付け、改修用上枠は既存上枠の外面部と平行なフランジ部を有し、該フランジ部が前記既存上枠の前記外面部に固着され、前記改修用上枠の内端部は前記既存上枠の内面部に固着される第１の内側下地金具に固定され、他方の改修用縦枠は他方の既存縦枠の外面部と平行なフランジ部を有し、該フランジ部が前記他方の既存縦枠の前記外面部に固着され、前記他方の改修用縦枠の内端部は前記他方の既存縦枠の内面部に固着される第２の内側下地金具に固定されるドアの改修構造に係り、又前記他方の改修用縦枠に鍵凹部が設けられ、前記他方の既存縦枠に前記鍵凹部が収納される切欠部を形成したドアの改修構造に係り、更に又前記他方の改修用縦枠に鍵凹部が設けられ、該鍵凹部は前記他方の既存縦枠より外部側に位置付けられたドアの改修構造に係るものである。
【００２０】
【発明の実施の形態】
以下、図面を参照しつつ本発明の実施の形態を説明する。
【００２１】
図１は左右の縦枠断面を示す部分断面図、図２は上下枠の断面を示す部分断面図を示し、図１、図２中、図５、図６中で示したものと同等のものには同符号を付してある。又、既存枠については従来例と同様であるので説明は省略する。

【００３０】
前記改修用縦枠３６は内端部が前記内側下地金具３５の側面部３５ｂに螺子等の固着具等にて固定され、前記フランジ部３６ｂが前記既存縦枠６の外面部に螺子等の固着具等にて固定される。前記フランジ部３６ｂと前記躯体１間との隙間には前記充填剤１５が充填され、前記溝３３には前記シール部材３４が嵌装される。
【００３１】
前記改修用縦枠３６の段差部の所要高さに、ドアに設けられた鍵のストライカ（図示せず）が嵌脱する鍵凹部３７が設けられ、該鍵凹部３７を挟んで上下に配設された補強部材３８が、前記既存縦枠６に固着される。前記補強部材３８は前記鍵凹部３７に対して破壊外力が作用した場合に、該鍵凹部３７の損傷を防止する。
【００３２】
図２に於いて、既存上枠１１、既存下枠１２の改修について説明する。
【００３３】
前記既存上枠１１に関する改修は、前記既存縦枠６に関する改修と同様に行われる。
【００３４】
前記既存上枠１１の内面部に断面Ｌ字状の内側下地金具３９が既存上枠１１の全長に亘って設けられ、前記内側下地金具３９の内面部３９ａが前記既存上枠１１の内面部に螺子等の固着具等にて固定される。前記内側下地金具３９の下面部３９ｂは下方に突出しており、前記既存上枠１１の下面部と前記下面部３９ｂ間には隙間が形成される。
【００３５】
前記内側下地金具３９の前記下面部３９ｂと前記既存上枠１１の外面部間に掛渡って改修用上枠４１が設けられる。該改修用上枠４１は１枚のステンレス鋼板等の金属板を屈曲成形したものであり、前記改修用縦枠３６と略同様な形状をしており、段差部、溝３３、上枠部４１ａ、フランジ部４１ｂが形成されている。
【００３６】
前記改修用上枠４１は内端部が前記内側下地金具３９の下面部３９ｂに螺子等の固着具等にて固定され、前記フランジ部４１ｂが前記既存上枠１１の外面部に螺子等の固着具等にて固定される。前記フランジ部４１ｂと前記躯体１間との隙間には前記充填剤１５が充填され、前記溝３３には前記シール部材３４が嵌装される。
【００３７】
前記既存下枠１２に改修用下枠４４が前記既存下枠１２の全長に亘りスペーサ４２，４３を介して螺子等の固着具等にて固定される。
【００３８】
前記改修用下枠４４は前記既存下枠１２の段差部に対応する段差部が形成され、段差部の境界には溝３３が形成され、前記改修用下枠４４の内端部、外端部はそれぞれ折返されている。
【００３９】
前記改修用縦枠３２、改修用縦枠３６、改修用上枠４１、改修用下枠４４の段差部は改修用扉体１０の収納部を形成する。該改修用扉体１０は蝶番２６を介して前記改修用縦枠３２に取付けられ、前記改修用扉体１０が閉じられた状態では、前記改修用縦枠３２、改修用縦枠３６、改修用上枠４１、改修用下枠４４の段差部に嵌り、前記溝３３は前記改修用扉体１０の上下左右の縁に圧縮した状態で密着する。
【００４０】
前記改修用縦枠３２を取付ける場合、前記スペーサ２９の枚数、厚みを調整して前記改修用縦枠３２の鉛直を出す。該改修用縦枠３２の鉛直が出ると、該改修用縦枠３２の段差部分を前記スペーサ２９を挾んだ状態で前記既存縦枠５に螺子等の固着具等にて固定する。前記内側下地金具２８の側面部２８ｂを前記改修用縦枠３２の内端部裏面に当接した状態で、前記内側下地金具２８の内面部２８ａを前記既存縦枠５の内面部に螺子等の固着具等にて固定する。
【００４１】
前記改修用下枠４４を取付ける場合、前記スペーサ４２，４３の厚み、枚数を調整して前記改修用下枠４４を基準として対角線の寸法（対角寸法）が所定寸法となる様に前記改修用下枠４４を螺子等の固着具等にて固定する。
【００４２】
而して、前記改修用縦枠３２が鉛直、及び前記改修用下枠４４が前記改修用縦枠３２を基準とした所定対角寸法に取付けられる。前記改修用上枠４１及び改修用縦枠３６を取付ける場合は、同様に前記改修用縦枠３２を基準として対角寸法が予定寸法となる様に配置し、前記改修用縦枠３６のフランジ部３６ｂを既存縦枠６に螺子等の固着具等にて固定し、又前記改修用上枠４１のフランジ部４１ｂを前記既存上枠１１に螺子等の固着具等にて固定する。
【００４３】
次に、前記内側下地金具３５の側面部３５ｂを前記改修用縦枠３６の内端部裏面に当接させた状態で、前記内面部３５ａを前記既存縦枠６の内面部に螺子等の固着具等にて固定する。更に、前記改修用縦枠３６の内端部を前記側面部３５ｂに螺子等の固着具等にて固定する。同様に、前記内側下地金具３９の下面部３９ｂを前記改修用上枠４１の内端部裏面に当接させた状態で、前記内面部３９ａを前記既存上枠１１の内面部に螺子等の固着具等にて固定する。更に、前記改修用上枠４１の内端部を前記下面部３９ｂに螺子等の固着具等にて固定する。
【００４４】
上述の如く、先ず、前記改修用縦枠３２を鉛直となる様調整して取付け、該改修用縦枠３２を基準として前記改修用下枠４４、前記改修用縦枠３６、改修用上枠４１が取付けられるので、前記既存縦枠５，６、既存上枠１１、既存下枠１２の水平、鉛直に狂いがあっても前記改修用縦枠３２、改修用縦枠３６、改修用上枠４１、改修用下枠４４はより正確に取付けられる。
【００４５】
而して、既存のドア枠に狂いがあっても、改修枠のフランジ部を既存枠に取付ける際、或は改修枠を内側下地金具を介して既存枠に固定する際に、狂いが修正され、より正確なドアの改修が行える。
【００４６】
尚、一方の改修用縦枠以外の残りの３本の改修用枠は、取付ける順番は任意だが、何れの場合も一方の改修用縦枠を基準に所定の対角寸法を出して取付ける様にする。
【００４７】
図３は第２の実施の形態を示している。
【００４８】
上記した第１の実施の形態では、前記鍵凹部３７の分だけ間口が狭くなっているが、第２の実施の形態では間口をより広くする改修方法である。
【００４９】
図３は前記鍵凹部３７が設けられている縦枠部分を示している。尚、図３中、図１中で示したものと同等のものには同符号を付し説明を省略する。又、他方の縦枠については第１の実施の形態と同様である。
【００５０】
内側下地金具４５の内面部４５ａは第１の実施の形態で示した前記内側下地金具３５の内面部３５ａよりも幅が狭くなっており、側面部４５ｂは前記既存縦枠６に近くなっている。従って、前記改修用縦枠３６は前記既存縦枠６に近接した状態で取付けられる。前記改修用縦枠３６が前記既存縦枠６に近接することで、前記鍵凹部３７が前記既存縦枠６に干渉する。この為、干渉部分を切除して該既存縦枠６に切欠部４６を設ける。尚、この場合、前記既存縦枠６が鍵凹部３７の補強部材として機能するので、第１の実施の形態で示した前記補強部材３８を取付ける必要はない。
【００５１】
図４は第３の実施の形態を示しており、該第３の実施の形態では外部に余裕がある場合である。
【００５２】
内側下地金具４５の内面部４５ａは第１の実施の形態で示した前記内側下地金具３５の内面部３５ａよりも幅が狭くなっており、前記改修用縦枠３６は前記既存縦枠６に近接した状態で取付けられる。前記鍵凹部３７が前記既存縦枠６と干渉しない様、外部側に外れた位置に設けられる。即ち、段差部が前記既存縦枠６の外端位置より外側となる様に前記改修用縦枠３６が形成される。形状としては前記縦枠部３６ａの高さが高くなり、前記鍵凹部３７は前記縦枠部３６ａに収納される。
【００５３】
尚、上記実施の形態で前記改修用縦枠３６のフランジ部３６ｂが外部側から螺子等の固着具等にて固定されるが、該フランジ部３６ｂにその固着具等の隠しとして、別途帯状の板を接着等により貼付ける様にしてもよい。
【００５４】
【発明の効果】
以上述べた如く本発明によれば、一方の既存縦枠に一方の改修用縦枠を鉛直に調整して取付け、該一方の改修用縦枠を基準に所定の対角寸法を求め、その後対角寸法を基準に他方の改修用縦枠、改修用上枠、改修用下枠を他方の既存縦枠、既存上枠、既存下枠に取付けるので、既存のドア枠の状態に拘らずより正確なドアの改修が行える。
【００５５】
又、一方の既存縦枠にスペーサを介して一方の改修用縦枠を鉛直に取付け、既存下枠にスペーサを介して改修用下枠を取付け、改修用上枠は既存上枠の外面部と平行なフランジ部を有し、該フランジ部が前記既存上枠の前記外面部に固着され、前記改修用上枠の内端部は前記既存上枠の内面部に固着される第１の内側下地金具に固定され、他方の改修用縦枠は他方の既存縦枠の外面部と平行なフランジ部を有し、該フランジ部が前記他方の既存縦枠の前記外面部に固着され、前記他方の改修用縦枠の内端部は前記他方の既存縦枠の内面部に固着される第２の内側下地金具に固定されるので、既存のドア枠に狂いがあっても、改修枠のフランジ部を既存枠に取付ける際、或は改修枠を内側下地金具を介して既存枠に固定する際に、狂いが修正され、より正確なドアの改修が行える。
【００５６】
又、前記他方の改修用縦枠に鍵凹部が設けられ、前記他方の既存縦枠に前記鍵凹部が収納される切欠部を形成し、或は前記他方の改修用縦枠に鍵凹部が設けられ、該鍵凹部は前記他方の既存縦枠より外部側に位置付けられたので、開口部の間口を殆ど狭くすることなく改修工事が行える等の優れた効果を発揮する。
