Description

本発明は、火災が生じたときヒューズによってそのことを検知し、延焼防止用可動羽根によって空気の流通を遮断し以て一定時間以上延焼を防止する延焼防止用ヒューズダンパーを備えた延焼防止用ヒューズダンパー付ルーバに関する。   The present invention relates to a fire spread prevention fuse having a fire spread prevention fuse damper that detects the occurrence of a fire by a fuse and prevents the spread of fire for a certain period of time by interrupting the flow of air with a movable blade for preventing fire spread. It relates to a louver with a damper.

本願発明者は防水・防音ルーバ等について特願平２−１９７７９１等により各種提案を行い、それが特許第２５６７２９４号公報等により公開された。
このような提案は、建築物の外部から内部への主として雨水等の侵入の防止に関するものである。 The inventor of the present application made various proposals regarding waterproof / soundproof louvers in Japanese Patent Application No. 2-197791 and the like, which was disclosed in Japanese Patent No. 2567294.
Such a proposal relates mainly to prevention of intrusion of rainwater or the like from the outside to the inside of the building.

しかし、ルーバに火災が発生したとき延焼を防止する機能を備させるという要請があり、その要請に応えるべくヒューズダンパー付ルーバの開発も行われており、本願発明者もその開発を進めている。
一般のヒューズダンパーは、複数枚の延焼防止用可動羽根をルーバの背後に設け、該延焼防止用可動羽根をそのルーバを通じての空気の流通を遮断する方向にスプリングにより付勢し、更に、ヒューズをその付勢力に抗して延焼防止用可動羽根をそのルーバを通じての空気の流通を許容する向きに保持するように取り付けるようにしたものである。 However, there is a request to provide a function for preventing the spread of fire when a fire occurs in the louver, and a louver with a fuse damper has been developed in response to the request, and the present inventor has also been developing the louver.
A general fuse damper has a plurality of fire spreading prevention movable blades behind a louver, and the fire spreading prevention movable blades are energized by a spring in a direction to block the air flow through the louver. The movable fire blade for preventing fire spread is attached against the urging force so as to be held in a direction allowing the air flow through the louver.

このようなヒューズダンパーによれば、火災が発生したときにヒューズがその火災による熱で溶断し、上記付勢力に抗する力を失い、上記延焼防止用可動羽根はその付勢力によりルーバを背後から閉塞し、ルーバを通じての延焼を一定時間（例えば２０分）以上防止することができる。すると、その延焼を防止している時間内に消防署への通報等による消防自動車等による消火活動が期待できる。
特許第２５６７２９４号公報（特願平２−１９７７９１） According to such a fuse damper, when a fire occurs, the fuse is blown by heat due to the fire and loses the force against the urging force, and the movable blade for preventing the spread of fire spreads the louver from behind by the urging force. It can be blocked and fire spread through the louver can be prevented for a certain time (for example, 20 minutes) or longer. Then, fire fighting activities such as fire engines by reporting to the fire department etc. can be expected within the time when the fire spread is prevented.

本ルーバ２は、ヒューズ４４が溶断していない通常においては、各可動横羽根２４、２４、・・・が空気の流通を略最大限許容する向きに保たれており、本ルーバ２は屋内外間の空気の流通を許容した状態を保つ。
そして、火災の発生によりヒューズ４４が溶断すると、スプリング５０の付勢力により連結板３６が上方向に移動せしめられる。すると、その移動力が各伝動突起５６、５６、・・・及び伝動片５２、５２、・・・を介して回動軸３４、３４、・・・に伝達され、該回動軸３４、３４、・・・を矢印Ａｒ２に示す方向に回動させる。その結果、可動横羽根２４、２４、・・・がその方向に回動してほぼ完全に屋内外間の空気の流通を遮断する向きになり、上記スプリング５０の付勢力によりその状態が保たれる。
従って、火災が発生しても一定時間（例えば２０分間）延焼を防止することができる。 In the normal case where the fuse 44 is not blown, the main louver 2 is maintained in a direction in which the movable horizontal blades 24, 24,. Keep the air flow allowed.
When the fuse 44 is melted due to the occurrence of a fire, the connecting plate 36 is moved upward by the urging force of the spring 50. Then, the moving force is transmitted to the rotation shafts 34, 34,... Via the transmission protrusions 56, 56,... And the transmission pieces 52, 52,. Are rotated in the direction indicated by the arrow Ar2. As a result, the movable horizontal blades 24, 24,... Rotate in that direction to almost completely block the air flow between the indoor and the outdoor, and the state is maintained by the biasing force of the spring 50. .
Therefore, even if a fire occurs, it is possible to prevent the spread of fire for a certain time (for example, 20 minutes).

そして、延焼防止用ヒューズダンパー８が、ヒューズ４４を除きルーバ本体４の内部空間に納められているので、ルーバ設置箇所から後側にヒューズダンパー８全体が大きく突出してルーバ設置箇所の美観を大きく損ねたり、ルーバを取り付けた施設等建築物の内部空間の有効利用を阻んだりし、延焼防止用ヒューズダンパー付ルーバの利用用途の拡大が阻まれることを防止することができる。   And since the fuse damper 8 for preventing fire spread is housed in the internal space of the louver body 4 except for the fuse 44, the entire fuse damper 8 protrudes greatly from the louver installation location to the rear side, and the aesthetics of the louver installation location are greatly impaired. In addition, it is possible to prevent the effective use of the internal space of a building such as a facility to which a louver is attached, and to prevent the expansion of the usage of the louver with a fuse damper for preventing fire spread.

本発明は、火災が生じたときヒューズによってそのことを検知し、延焼防止用可動羽根によって空気の流通を遮断し以て一定時間以上延焼を防止する延焼防止用ヒューズダンパーを備えた延焼防止用ヒューズダンパー付ルーバ全般に利用可能性がある。   The present invention relates to a fire spread prevention fuse having a fire spread prevention fuse damper that detects the occurrence of a fire by a fuse and prevents the spread of fire for a certain period of time by interrupting the flow of air with a movable blade for preventing fire spread. It can be used for all louvers with dampers.
