（新設下枠の室外側支持のための実施形態）
以下、本発明の実施形態の改修建具における、新設下枠の室外側の支持構造、火災時の変形等による新設下枠２２の室外側の浮き上がりを防止するための構成、室外側の新設下枠と既設下枠との間からの火炎等の侵入を抑制するための構成について、さらに詳細に説明する。 (Embodiment for supporting the outdoor side of the newly installed lower frame)
Hereinafter, in the modified fitting of the embodiment of the present invention, the structure for preventing the outdoor side of the new lower frame 22 from rising due to the support structure of the outdoor side of the new lower frame, the deformation at the time of fire, etc., the new outdoor lower frame The configuration for suppressing the intrusion of flames and the like from between the and the existing lower frame will be described in more detail.

新設下枠２２が既設下枠１２の内周に配置された状態では、室内側においては、室内側底壁部２２ａの下面の内外２か所に形成された脚部が室内側取付補助材３２１の支持部３２１ａに載置されてビス等の固定手段ｂにより室内側取付補助材３２１に固定されている。
そして、室外側においては、室外側底壁部２２ｂの下面が、既設下枠１２の室外側に固定される室外側取付補助材３２２の支持部３２２ａの上方に配置されており、新設下枠２２は室内側取付補助材３２１及び室外側取付補助材３２２を介して既設下枠１２に支持されている。 In the state where the new lower frame 22 is arranged on the inner circumference of the existing lower frame 12, on the indoor side, the legs formed at two places inside and outside the lower surface of the indoor side bottom wall portion 22a are the indoor side mounting auxiliary material 321. It is placed on the support portion 321a of the above and is fixed to the indoor side mounting auxiliary material 321 by a fixing means b such as a screw.
On the outdoor side, the lower surface of the outdoor bottom wall portion 22b is arranged above the support portion 322a of the outdoor mounting auxiliary material 322 fixed to the outdoor side of the existing lower frame 12, and the new lower frame 22 is installed. Is supported by the existing lower frame 12 via the indoor side mounting auxiliary material 321 and the outdoor side mounting auxiliary material 322.

ここで、本実施形態の改修建具における室外側取付補助材３２２は、アルミ合金等の金属製の長尺部材からなり、図５（ｂ）に示すように、既設下枠１２の前壁部に固定される固定部３２２ｃと、固定部３２２ｃの上方に連続して室内方向して屈曲して形成される支持部３２２ａと、固定部３２２ｃの下方で室外側に延設される浮き上がり防止部（対向片）３２２ｂとを有している。 Here, the outdoor mounting auxiliary material 322 in the repair fitting of the present embodiment is made of a long metal member such as an aluminum alloy, and is formed on the front wall portion of the existing lower frame 12 as shown in FIG. 5 (b). The fixed portion 322c to be fixed, the support portion 322a formed by being continuously bent in the indoor direction above the fixed portion 322c, and the floating prevention portion (opposing) extending to the outdoor side below the fixed portion 322c. Piece) 322b and has.

そして、室外側取付補助材３２２は、見付け方向の複数位置において、ビス等の固定手段ｂ１により既設下枠１２の前壁部に固定されており、必要に応じて支持部３２２ａの上面において新設下枠２２の下面を支持している。 The outdoor mounting auxiliary material 322 is fixed to the front wall portion of the existing lower frame 12 by fixing means b1 such as screws at a plurality of positions in the finding direction, and is newly installed on the upper surface of the support portion 322a as needed. It supports the lower surface of the frame 22.

この時、支持部３２２ａの下面と既設下枠１２の内周（上）面との間にスペーサー６３を配置して、室外側取付補助材３２２を下方より支持してもよく、これにより新設下枠２２を室外側取付補助材３２２の支持部３２２ａにより支持する際に、新設枠２の荷重を既設下枠１２に直接伝えることができ、新設建具の安定した支持を行うことができる。
また、室外側底壁部２２ｂの上面に立設される室外下レール２２ｉの下方位置近傍において、室外側取付補助材３２２の支持部３２２ａが新設下枠２２の室外側底壁部２２ｂを支持することで、室外下レール２２ｉ上に配置される外障子５の重量を安定して受けることができる。 At this time, a spacer 63 may be arranged between the lower surface of the support portion 322a and the inner peripheral (upper) surface of the existing lower frame 12 to support the outdoor mounting auxiliary material 322 from below, whereby the newly installed lower frame 12 may be supported. When the frame 22 is supported by the support portion 322a of the outdoor mounting auxiliary material 322, the load of the new frame 2 can be directly transmitted to the existing lower frame 12, and the new fitting can be stably supported.
Further, in the vicinity of the lower position of the outdoor lower rail 22i erected on the upper surface of the outdoor bottom wall portion 22b, the support portion 322a of the outdoor mounting auxiliary material 322 supports the outdoor bottom wall portion 22b of the newly installed lower frame 22. As a result, the weight of the external shoji 5 arranged on the outdoor lower rail 22i can be stably received.

また、新設下枠２２の前壁部２２ｆの外周部位から室内側に延設される浮き上がり防止片(係合片)２２ｇが、室外側取付補助材３２２の浮き上がり防止部（対向片）３２２ｂの下方位置に配置されて上下方向に対向しているので、新設下枠２２の室外側に下方から外力がかかっても、浮き上がり防止片２２ｇが室外側取付補助材３２２の浮き上がり防止部３２２ｂに下方から当接して、新設下枠２２の室外側の浮き上がりを抑制することができる。 Further, the floating prevention piece (engagement piece) 22g extending from the outer peripheral portion of the front wall portion 22f of the new lower frame 22 to the indoor side is below the floating prevention portion (opposing piece) 322b of the outdoor mounting auxiliary material 322. Since it is arranged at a position and faces in the vertical direction, even if an external force is applied to the outdoor side of the newly installed lower frame 22 from below, the lift prevention piece 22 g hits the lift prevention portion 322b of the outdoor mounting auxiliary material 322 from below. In contact with each other, it is possible to suppress the floating of the outdoor side of the newly installed lower frame 22.

さらに、新設下枠２２は、新設下枠２２を強固に既設下枠１２に固定する必要がある場合などには、図５（ｃ）に示すように、室外側取付補助材３２２の既設下枠１２への固定位置と見付け方向で異なる位置において、室外側底壁部２２ｂの上面から室外側取付補助材３２２の浮き上がり防止部３２２ｂに対するビス等の固定手段ｂ２によって固定してもよい。 Further, in the new lower frame 22, when it is necessary to firmly fix the new lower frame 22 to the existing lower frame 12, as shown in FIG. 5 (c), the existing lower frame of the outdoor mounting auxiliary material 322 is used. It may be fixed by a fixing means b2 such as a screw from the upper surface of the outdoor bottom wall portion 22b to the floating prevention portion 322b of the outdoor mounting auxiliary material 322 at a position different from the fixing position to 12 in the finding direction.

以上のように、本実施形態の改修建具によれば、新設下枠２２の室外側を支持する室外側取付補助材３２２が、見込み方向に短い寸法の長尺部材により形成されているので、既設下枠１２の形状や経年変形の影響を受けにくく取付位置を簡単に調節することができ、新設下枠２２を正確に支持することができる。 As described above, according to the refurbished fitting of the present embodiment, the outdoor mounting auxiliary material 322 that supports the outdoor side of the newly installed lower frame 22 is formed of a long member having a short dimension in the prospective direction. The mounting position can be easily adjusted without being affected by the shape of the lower frame 12 and the aging deformation, and the newly installed lower frame 22 can be accurately supported.

また、室外側取付補助材３２２を既設下枠１２に固定するための固定部３２２ｃは、室外側取付補助材３２２の固定部３２２ｃの下端から室外側に延設された浮き上がり防止部３２２ｂにより隠されるので、室外側取付補助材３２２の固定部分を室外の影響から保護することができ、劣化を抑制することができるとともに、新設下枠２２と既設下枠１２との室外側の隙間を室外側取付補助材３２２によって塞ぐことによって、火災時に該隙間を介して火炎や煙等が侵入することを抑制し、延焼を防ぐことができる。 Further, the fixing portion 322c for fixing the outdoor mounting auxiliary material 322 to the existing lower frame 12 is hidden by the floating prevention portion 322b extending from the lower end of the fixing portion 322c of the outdoor mounting auxiliary material 322 to the outdoor side. Therefore, the fixed portion of the outdoor mounting auxiliary material 322 can be protected from the influence of the outdoor, deterioration can be suppressed, and the outdoor gap between the new lower frame 22 and the existing lower frame 12 can be mounted on the outdoor side. By closing with the auxiliary material 322, it is possible to suppress the invasion of flames, smoke and the like through the gap in the event of a fire, and prevent the spread of fire.

なお、以上の実施形態は，請求項に記載された発明を限定するものではなく，例示として取り扱われることは言うまでもない。
例えば、室外側取付補助材３２２の支持部３２２ａと既設下枠１２との間に配置されるスペーサー６３は、省略してもよい。また、新設下枠２２の室外側底壁部２２ｂの下面は、必ずしも支持部３２２ａに当接しなくてもよく、新設下枠２２が撓んだときに当接するものでもよい。
さらに、改修される既設枠及び新設建具は、引違い建具に限定されるものではなく、開き建具やすべり出し建具等、建具の種類は何ら限定されるものではない。 Needless to say, the above embodiments do not limit the invention described in the claims, and are treated as examples.
For example, the spacer 63 arranged between the support portion 322a of the outdoor mounting auxiliary material 322 and the existing lower frame 12 may be omitted. Further, the lower surface of the outdoor bottom wall portion 22b of the new lower frame 22 does not necessarily have to abut on the support portion 322a, and may abut when the new lower frame 22 bends.
Furthermore, the existing frames and new fittings to be repaired are not limited to sliding fittings, and the types of fittings such as open fittings and sliding fittings are not limited at all.
