【０００８】
【実施例】
本発明の一実施例の既設外壁補強構造及び既設の外壁補強方法を図面を参照して説明する。
図１乃至図８において、１は外壁で、外壁１の内方に既設の壁下地材Ｓが位置している。この壁下地材Ｓは、少なくとも、平行な第１の横材２（例えば、水平部材である土台）、第２の横材３（例えば、水平部材であるけた）と、第１、第２の横材２、３に垂直な第１の縦材４（例えば、水平部材に垂直な第１の柱）、第２の縦材５（例えば、水平部材に垂直な第２の柱）とで構成された長方形の骨組みＨを有している。
６は、第１の縦材４（例えば、第１の柱）と第２の縦材５（例えば、第２の柱）との間に設けられた間柱である。
【０００９】
図１に示す既設の外壁１に筋交いＤを入れて補強するには、先ず、図２に示すように、長方形の骨組みＨの一方の角部に対向する位置の既設の外壁１の部分を切除して第１の開口部Ｋ1 を、長方形の骨組みＨの他方の角部に対向する位置の既設の外壁１の部分を切除して第２の開口部Ｋ2 を、後述する締結具Ｄ3 （締結具Ｄ3 は、例えば、タ−ンバックルである。）に対向する位置の既設の外壁１の部分を切除して第３の開口部Ｋ3 をそれぞれ形成する。
長方形の骨組みＨの一方の角部と長方形の骨組みＨの他方の角部とは、対角に設けられている。
【００１０】
第１の開口部Ｋ1 の大きさは、後述する第１の固定部材Ｒ1 を外部より前記一方の角部に、入れることができる大きさであり、また、第２の開口部Ｋ2 の大きさは、後述する第２の固定部材Ｒ2 を外部より前記他方の角部に、入れることができる大きさであり、また、第３の開口部Ｋ3 の大きさは、後述する締結具Ｄ3 を外部より外壁１の内方に位置した既設の壁下地材内に、入れることができる大きさとなっている。
【００１１】
筋交いＤは、図３に示すように、外壁１の施工後、長方形の骨組みＨの対角線に設けられるもので、この筋交いＤは中途に締結具Ｄ3 （締結具Ｄ3 は、例えば、タ−ンバックルである。）が設けられ、筋交いＤの一端は、長方形の骨組みＨの一方の角部に外壁１の施工後に設けられた第１の固定部材Ｒ1 に、筋交いＤの他端は、長方形の骨組みＨの他方の角部に外壁１の施工後に設けられた第２の固定部材Ｒ2 にそれぞれ接続されるものである。
【００１２】
即ち、筋交いＤは、一端を第１の固定部材Ｒ1 に他端を締結具Ｄ3 に接続される第１の棒状部材Ｄ1 と、一端を締結具Ｄ3 に他端を第２の固定部材Ｒ2 に接続される第２の棒状部材Ｄ2 とを有している。
第１の棒状部材Ｄ1 は第１の開口部Ｋ1 又は第３の開口部Ｋ3 より入れるものであり、また、第２の棒状部材Ｄ2 は第２の開口部Ｋ2 又は第３の開口部Ｋ3 より入れるものであり、締結具Ｄ3 は第３の開口部Ｋ3 より入れる。
そして、第１の棒状部材Ｄ1 の一端を第１の固定部材Ｒ1 に第１の棒状部材Ｄ1 の他端を締結具Ｄ3 に接続すると共に、第２の棒状部材Ｄ2 の一端を締結具Ｄ3 に第２の棒状部材Ｄ2 の他端を第２の固定部材Ｒ2 に接続して、筋交いＤを形成することができる（図３乃至図５参照）。
【００１３】
なお、第１の固定部材Ｒ1 及び第２の固定部材Ｒ2 は、雄螺子等により既設の壁下地材（例えば、第１の固定部材Ｒ1 は壁下地材の第２の横材３と第２の縦材５に、第２の固定部材Ｒ2 は第１の横材２と第１の縦材４に、それぞれ雄螺子等により固定されている。）に取り付けられている。
そして、第１の固定部材Ｒ1 に設けられた雌螺子に螺合する雄螺子を第１の棒状部材Ｄ1 の一端は備えている。また、第２の固定部材Ｒ2 に設けられた雌螺子に螺合する雄螺子を第２の棒状部材Ｄ2 の一端は備えている。
更に、第１の棒状部材Ｄ1 の他端に設けられた雄螺子に螺合する第１の雌螺子が締結具Ｄ3 （締結具Ｄ3 は、例えば、タ−ンバックルである。）の第１の棒状部材Ｄ1 の側に、第２の棒状部材Ｄ2 の他端に設けられた雄螺子に螺合する第２の雌螺子が締結具Ｄ3 （締結具Ｄ3 は、例えば、タ−ンバックルである。）の第２の棒状部材Ｄ2 の側に、それぞれ設けられている。
【００１４】
その結果、上述した既設外壁補強構造によれば、既設外壁に第１の開口部Ｋ1 、第２の開口部Ｋ2 及び第３の開口部Ｋ3 を設け、既設外壁内に筋交いＤを取りつけることができ、外壁１全体を取り外す必要がないため、大掛かりな作業を伴わず、筋交いＤを既設外壁１の内部に設置して既設の外壁１の補強を図ることができる。
【００１５】
また、図６乃至図８に示すように、Ｆ1 は第１の開口部Ｋ1 を着脱自在に、例えば、ビスＢで、蓋をする第１の蓋で、Ｆ2 は第２の開口部Ｋ2 を着脱自在に、例えば、ビスＢで、蓋をする第２の蓋で、Ｆ3 は第３の開口部Ｋ3 を着脱自在に、例えば、ビスＢで、蓋をする第３の蓋である。
つまり、第１の蓋Ｆ1 は第１の開口部Ｋ1 を隠す着脱自在な蓋で、第２の蓋Ｆ2 は第２の開口部Ｋ2 を隠す着脱自在な蓋で、第３の蓋Ｆ3 は第３の開口部Ｋ3 を隠す着脱自在な蓋である。
このように、着脱自在な第１の蓋Ｆ1 、第２の蓋Ｆ2 及び第３の蓋Ｆ3 とすることにより、筋交いＤ（例えば、筋交いＤの経時的な緩み等）の保守点検が容易となる。
【００１６】
なお、筋交いＤの形態は、上述の場合に限らず、例えば、図９に示すように、筋交いＤを並設しても良いし、また、図10に示すように、筋交いＤをクロスするようにしても良い。
【００１７】
また、締結具Ｄ3 はタ−ンバックルの例を挙げたが、本発明にあっては、これに限らず、第１の棒状部材Ｄ1 と第２の棒状部材Ｄ2 を締結するものであれば良く、
また、締結具Ｄは第３の開口部Ｋ3 より入れたが、本発明にあっては、これに限らず、第１の棒状部材Ｄ1 を第１の棒状部材Ｄ1 の他端に締結具Ｄ3 に接続した状態で、第１の開口部Ｋ1 又は第３の開口部Ｋ3 より入れても良い（この場合、第１の開口部Ｋ1 又は第３の開口部Ｋ3 より第１の棒状部材Ｄ1 を既設の壁下地材Ｓ内に入れた後、第１の棒状部材Ｄ1 の一端を第１の固定部材Ｒ1 に接続すると共に、第２の棒状部材Ｄ2 の一端を締結具Ｄ3 に第２の棒状部材Ｄ2 の他端を第２の固定部材Ｒ2 に接続して、筋交いＤを形成する。）し、また、第２の棒状部材Ｄ2 を第２の棒状部材Ｄ2 の他端に締結具Ｄ3 に接続した状態で、第２の開口部Ｋ2 又は第３の開口部Ｋ3 より入れても良い（この場合、第２の開口部Ｋ2 又は第３の開口部Ｋ3 より第２の棒状部材Ｄ2 を既設の壁下地材Ｓ内に入れた後、第１の棒状部材Ｄ1 の一端を第１の固定部材Ｒ1 に第１の棒状部材Ｄ1 の他端を締結具Ｄ3 に接続すると共に、第２の棒状部材Ｄ2 の一端を締結具Ｄ3 に接続して、筋交いＤを形成する。）。
