Description

M430523 101年.03月29日俊正替換頁 五、新型說明： 【新型所屬之技術領域】 [0001] 本創作關於一種無鎖金屬防火門，主要指一種不須 額外增加鎖體可具阻隔防火功效，並可提升建築物整體 質感。 【先前技術】 [0002] 習知防火門常安裝在公共場合之通道位置，並該防
火門可具單開、雙開、90°、180°、270 °、360 °開啟等 多種型式，且依需求具常閉或常開設計，並該防火門必 須於門體一側加熱時其另一側背溫須於設定值以下，且 其變形量及抗衝擊性須符合測試規定，使得當火災時可 藉由防火門阻隔火焰滲入以提供防火安全功效。 [0003] 就防火門體結構而言，主要具二金屬門板，並於二 門板間設置防火骨架或各式防火心材，並於防火門體上 設置可與外框扣合之鎖體，而該鎖體一般為定位功能， 使用者可開啟以提供人員可出入，並對常開式防火門體 而言該鎖體平時並無功能。 [0004] 然而因該防火門體之鎖體係外凸於門板外側，造成 該防火門不能與建築壁面搭配情形，並使得建築物不具 整體質感缺失。 【新型内容】 [0005] 本創作之目的在提供一種不須防火門鎖即可具阻隔 防火功效，並可提升建築物整體質感。 [0006] 10120031#單編號 A〇101 本創作另一目的在提供一種可減小防火門中央受熱 1013120488-0 第3頁/共12頁 M430523 [0007] [0008] [0009] 101年03月29日核正替換頁 變形量結構。 本創作之防火門體樞設於外框上，並該防火門體具 二金屬門板，並於二門板内設置防火機構，並該防火機 構可包括防火骨架、防火心材，又於防火門體設置可自 動歸位之鉸鍊，並該鉸鍊可為門體下方之地鉸鍊或門體 左、右裝設可自動歸位之旗形鉸鍊或蝶形鉸鍊，並該防 火門體與外框間距可當防火門體受熱時其金屬門板遇熱 擴張之變形量可抵靠外框；藉此本創作防火門體可藉由 鉸鍊動作到位及定位，且防火門體到位後可藉由其自重 定位，又當防火門體一側受熱時該防火門體側方受熱擴 張可與外框緊密抵觸以具穩固迫緊定位及阻隔火焰功效 ，因而本創作不須設置防火門鎖即可具防火阻熱功效， 並可使得防火門體可與建築物結合具較佳整體質感。 本創作之防火門體可為常閉或常開型式，並當防火 門體為長開型式時係藉由電磁閥定位於展開位置，並當 有火災時令電磁閥斷電即可令防火門體藉由鉸鍊自動位 移至閉合位置，並防火門體受熱一段時間後該防火門體 側邊即可擴張與外框緊密抵靠以具穩固定位功效，又本 創作可適用於單扇或雙扇設計，並於防火門體側邊設置 擋片，並使雙扇防火門體關閉時該一防火門體之擋片可 與另一防火門體貼靠以具防止火焰及煙滲入功效。 本創作之防火門體之門板中央可設置缺口組設接合 板，並於缺口位置設置内凹接合部，並該接合部具側邊 、接合邊；又該接合板可具裝飾形體，並於側邊設置内 凸接合部，並該内凸接合部具内凸側邊、内凸接合邊，
1012_#單编號删1 第4頁/共12頁 1013120488-0 M430523 101年.03月29日修正替换頁 並使接合板可置於缺口位置，並使内凸接合邊與門板之 接合邊焊接固定，且使内凸側邊與門板之側邊具緩衝間 距；藉此於防火門體一側加熱時該接合板受熱變形擴張 時可向緩衝間距位置擴張，不會直接擠壓門板，並使本 創作之門體側方可擴張與外框抵靠，但門板中央受熱變 形量可減小，可具減小門體中央變形量功效。 [0010] • 【實施方式】 請參閱第一圖，本創作之防火門體1樞設於外框2上 ，並該防火門體1具二金屬門板11，並於二門板11内設置 防火機構12，又於防火門體1下方設置可自動歸位之地鉸 鍊13，並該防火門體1與外框2間具可當防火門體1受熱時 其金屬門板11遇熱擴張之變形量可抵靠外框2之間距10， 又於防火門體側邊設置擋片15。 [0011] • 請參閱第二、三圖，本創作防火門體1可藉由地鉸鍊 13動作到位及定位，且防火門體1到位後可藉由其自重定 位，又當防火門體1 一侧受熱時該防火門體1侧方擴張可 與外框2如圖a位置緊密抵觸，以具穩固迫緊定位功效， 並使防火門體1受外力衝擊時不會被推開，因而本創作不 須設置防火門鎖即可具防火阻熱功效，並可使得防火門 體1可與建築物結合具整體質感。 [0012] 本創作之防火門體1可為常閉或常開型式，並如第五 、六圖所示為長開型式防火門，並該防火門體1係藉由電 磁閥14定位於展開位置，並圖中所示之防火門體1設於通 道3位置，並該通道3具電梯4，又當有火災時令電磁閥14 斷電即可令防火門體1藉由地鉸鍊13自動位移至如第五圖 10120031# 單編號 A〇101 第5頁/共12頁 1013120488-0 财30523 101年03月29日梭正替換頁 所示閉合位置，並防火門體1受熱一段時間後該防火門體 1側邊即可擴張與外框2緊密抵靠以具穩固定位功效。 [0013] 請參閱第六、七圖，本創作之防火門體1之門板11中 央可設置缺口 16組設接合板18，並於缺口 16位置設置内 凹接合部17，並該接合部17具側邊171、接合邊172 ;又 該接合板18可具裝飾形體，並於側邊設置内凸接合部181 ’並該内凸接合部181具内凸側邊182、内凸接合邊183 ，並使接合板18可置於缺口 16位置，並使内凸接合邊183 與門板11之接合邊172焊接固定，且使内凸側邊182與門 | 板11之接合部17侧邊171具緩衝間距19 ;藉此於防火門 體1 一側如箭頭方向加熱時該接合板18受熱變形擴張時可 向緩衝間距19位置擴張，不會直接擠壓門板u，並使本 創作之門體1侧方可擴張與外框2抵靠，但門板丨丨中央受 熱變形量可減小，可具更佳防火阻熱功效， [0014] 是以由以上所述，本創作可具整體質感及良好防火 阻熱功效，並本創作之鉸鍊亦可為旗形鉸鍊或蝶形鉸鍊 ，而前述實施例為本創作例示，並非本創作限制，凡依 痛 據本創作精神所為之等效改變亦應屬於本創作範疇内。 【圖式簡單說明】 [0015] [0016] [0017] 第-圖係本創作實施於雙扇常開防火門閉合示意圖。 第二圖縣㈣實施於雙扇常_火Η受齡Η體與外 框迫緊定位示意圖。 第二圖係本創作實施於雙扇常開防火門受熱令門體與外 框迫緊定位示意圖。 10120031#單编號 Α0101 第6頁/共12頁 1013120488-0 M430523 101年.03月29日修正替换頁 [0018] 第四圖係本創作實施於公共場合示意圖。 [0019] 第五圖係本創作實施於公共場合示意圖。 [0020] 第六圖係本創作防火門體具接合板示意圖。 [0021] 第七圖係本創作防火門體具接合板受熱示意圖。 【主要元件符號說明】 [0022] 1門體 10間距 11門板 - [0023] 12防火機構 13地敍鍊 14電磁閥 ’ [0024] 15擋片 1 6缺口 17接合部 [0025] 1 71側邊 172接合邊 18接合板 [0026] 181内凸接合部 182内凸側邊 183内凸接合邊 [0027] 1 9間距 2外框 3通道 - [0028] 4電梯 10120031产單編號 A0101 第7頁/共12頁 1013120488-0
