The window portion 2 of the fire-prevention fitting according to the present embodiment has fire protection properties. As shown in FIG. 2, the vertical frame 23 on the connecting member side is fixed to the frame attachment member 12, and the anti-connecting member side (frame opening) The vertical frame 24 (at the part A side) is attached to the skeleton opening A by being fixed to the anchor member 5 fixed to the skeleton opening A.
As shown in FIG. 4A, the vertical frame 23 (24) of the window portion 2 fixed to the connecting member 1 (and the anchor member 5) has at least a prospect wall 23a and an outer periphery from the indoor side end of the prospect wall 23a. An indoor mounting piece 23b extending toward the side and having a distal end bent in the outdoor direction, a hollow portion 23c provided on the outdoor outer peripheral surface of the prospective wall 23a, and an indoor end on the inner peripheral side of the hollow portion 23c. , And has an outdoor-side mounting piece 23d that extends toward the indoor direction and is bent and extended to the outer peripheral side.

そして、竪枠２３は、室内側取付片２３ｂが枠取付材１２の室内側取付部１２ｂに対して室外側から見込み方向に重複するように当接してビス等の固定手段ｂ８により固定されると共に、室外側取付片２３ｄの見付壁が枠取付材１２の室外側取付部１２ｅに対して室内側から見込み方向に重複するように当接してビス等の固定手段ｂ９によって固定されている。   The vertical frame 23 is fixed by the fixing means b8 such as a screw while the indoor side mounting piece 23b abuts on the indoor side mounting portion 12b of the frame mounting material 12 from the outdoor side in the expected direction. The finding wall of the outdoor-side mounting piece 23d abuts against the outdoor-side mounting portion 12e of the frame mounting material 12 from the indoor side in the expected direction and is fixed by fixing means b9 such as a screw.

枠取付材１２の室外側取付部１２ｅに固定された竪枠２３の室外側取付片２３ｄ，２３ｄの室外側であって、竪枠２３，２３の中空部２３ｃ，２３ｃの間には、シール材ｓが設けられており、竪枠２３，２３間が気密されている。
そして、防火建具の連結材１の室外側は、竪枠２３，２３の室外側面より室外側に突出する部材を配することなく、面一に形成されている。 A sealing material is provided between the outdoor portions 23d of the vertical frame 23 fixed to the outdoor mounting portion 12e of the frame mounting member 12 and the hollow portions 23c of the vertical frames 23. s is provided, and the space between the vertical frames 23 is airtight.
The outdoor side of the connecting member 1 of the fire-prevention fitting is formed flush without arranging a member protruding outward from the outdoor side surfaces of the vertical frames 23, 23.

以上のように、本実施形態の防火建具については、窓部２を支持する連結材１の連結材本体１１は、開口部の面積を確保するために見付け方向の寸法が小さく設定され、また、室外側面に突出部を設けることなく面一状態に施工するために見込み方向の寸法が小さく設定されている。
そのため、躯体開口部Ａにアンカー部材５を介して支持される連結材本体１１の断面積を十分に確保できず強度を保つことが難しかった。特に、開口高さ寸法の大きな建具については強度不足となることが多かった。 As described above, in the fire prevention fitting of the present embodiment, the connecting member main body 11 of the connecting member 1 supporting the window portion 2 is set to have a small dimension in the finding direction in order to secure the area of the opening. The dimension in the expected direction is set to be small in order to perform the construction in a flush state without providing a protruding portion on the outdoor side surface.
Therefore, the cross-sectional area of the connecting member main body 11 supported by the frame opening A via the anchor member 5 cannot be sufficiently secured, and it is difficult to maintain the strength. In particular, fittings having a large opening height often lack strength.

それに対して、本実施形態の防火建具は、連結材本体１１の室内側に配置される耐火部材１３２の更に室内側に、連結材１を補強する補強部材１３４を配置することで、連結材１の強度を向上させたものである。   On the other hand, in the fire prevention fitting of this embodiment, the reinforcing member 134 that reinforces the connecting member 1 is disposed further on the indoor side of the refractory member 132 disposed on the indoor side of the connecting member main body 11, so that the connecting member 1 Is improved.

具体的には、耐火部材１３２を覆う室内側カバー部材１３３に、補強部材１３４を配置することができる中空部１３３ｂを形成し、中空部１３３ｂ内に補強部材１３４を配置するとともに、補強部材１３４を室内側カバー部材１３３の中空部１３３ｂ内にビス等の固定手段ｂ７により固定することで、室内側カバー部材１３３の強度を高めている。
そして、強度が向上した室内側カバー部材１３３を、連結材本体１１に固定された連結部材１３１の係止片１３１ｂに対してネジ等の固定手段ｂ６によって固定することで、連結材本体１１と室内側カバー部材１３３とが一体となった強度の高い連結材１を構成している。 Specifically, a hollow portion 133b in which the reinforcing member 134 can be disposed is formed in the indoor side cover member 133 that covers the fireproof member 132, and the reinforcing member 134 is disposed in the hollow portion 133b, and the reinforcing member 134 The strength of the indoor-side cover member 133 is increased by being fixed in the hollow portion 133b of the indoor-side cover member 133 by fixing means b7 such as a screw.
Then, the indoor-side cover member 133 having improved strength is fixed to the locking piece 131b of the connecting member 131 fixed to the connecting member main body 11 by a fixing means b6 such as a screw, so that the connecting member main body 11 and the room are fixed. The high-strength connecting member 1 integrated with the inner cover member 133 is configured.

以上の実施形態の防火建具においては、連結材１を構成する連結材本体１１の室内側に耐火部材１３２が配置されるとともに、耐火部材１３２の室内側に補強部材１３４が配置されることで、連結材１全体の強度を向上させることができる。
したがって、連結材１の見付寸法を小さくすることができ、開口部分を広く保つことができる。また、連結材１の見込寸法を窓部の見込寸法よりも小さく形成することを可能にし、窓の室外側を面一に形成することができる。 In the fire prevention fitting of the above embodiment, the fireproof member 132 is arranged on the indoor side of the connecting member main body 11 constituting the connecting member 1, and the reinforcing member 134 is arranged on the indoor side of the fireproof member 132. The strength of the entire connecting member 1 can be improved.
Therefore, the apparent size of the connecting member 1 can be reduced, and the opening can be kept wide. In addition, it is possible to form the expected size of the connecting member 1 smaller than the expected size of the window portion, and it is possible to make the outside of the window flush with the window.

そして、連結材１全体の強度を高めるための補強部材１３４を、連結材１を構成する室内側カバー部材１３３に固定して、該室内側カバー部材１３３を連結材本体１１に固定された連結部材１３１に固定することで補強しているので、開口部の高さ寸法が小さい場合には、室内側カバー部材１３３を中空部を備えない室内側カバー部材に変更したり、中空部内に補強部材１３４を配置しないようにしたりすることなどで、連結材本体１１の構成を変更することなく、建具に応じた補強の設定を簡単に行うことができる。   Then, the reinforcing member 134 for increasing the strength of the entire connecting member 1 is fixed to the indoor-side cover member 133 constituting the connecting member 1, and the indoor-side cover member 133 is fixed to the connecting member main body 11. When the height of the opening is small, the indoor cover member 133 is changed to an indoor cover member having no hollow portion, or the reinforcing member 134 is provided in the hollow portion. By not disposing, for example, it is possible to easily set the reinforcement according to the fitting without changing the configuration of the connecting member main body 11.

なお、本実施形態においては、耐火部材の室内側に配置される補強部材１３４は，室内側カバー部材１３３の中空部内の室外側壁に固定されているが、補強部材１３４の固定は上記構成に限定されるものではなく、連結材１を補強することができれば、いずれの部材に固定されるものでもよい。   In the present embodiment, the reinforcing member 134 disposed on the indoor side of the fireproof member is fixed to the outdoor side wall in the hollow portion of the indoor side cover member 133, but the fixing of the reinforcing member 134 is limited to the above configuration. Instead, any member may be used as long as the connecting member 1 can be reinforced.

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。   It is needless to say that the above embodiments do not limit the invention described in the claims but are treated as examples.
