防火隔煙捲幕其門軌結構 Fireproof and smoke-proof curtain

本創作係有關於一種防火隔煙捲幕其門軌結構,此尤指一種可降低防火隔煙捲幕磨損之門軌結構,藉以增加防火隔煙捲幕作動的順暢性,有效阻止火勢及濃煙之蔓延者。 The present invention relates to a door rail structure of a fireproof smoke-proof roll screen, in particular to a door rail structure which can reduce the wear of the fireproof and smoke-proof roll screen, thereby increasing the smoothness of the fireproof and smoke-proof roll screen, effectively preventing the spread of fire and smoke. By.

為了確保人民生命財產的安全,在我國建築消防相關法規中,都訂有在建物中建構消防設施的規範,因此一些大型建築物被要求規劃有複數個防火區,藉由每一防火區其防火隔煙裝置的阻隔,使在火災發生時,能有效阻隔火勢的蔓延,以確保人員生命的安全;因此在防火區裝設防火隔煙捲幕,已被普遍採行。它的好處不外乎平常可以隱藏,不影響空間的使用,而在緊急時又能適時降下,以阻隔火勢的蔓延,因此防火隔煙捲幕已成為消防公安的重要設施。 In order to ensure the safety of people's lives and property, in China's building fire protection regulations, there are provisions for the construction of fire protection facilities in the construction, so some large buildings are required to plan a number of fire zones, through each fire zone to prevent fire The barrier of the smoke-proof device can effectively prevent the spread of the fire in the event of a fire to ensure the safety of the life of the person; therefore, the installation of a fire-proof smoke-proof curtain in the fire zone has been widely adopted. Its benefits are nothing more than the usual concealment, does not affect the use of space, and can be lowered in an emergency to prevent the spread of fire, so the fire-proof smoke-winding has become an important facility for fire-fighting public security.

為了發揮防火隔煙捲幕阻止火勢及濃煙蔓延的效果,所以該防火隔煙捲幕與門軌之間的氣密效果,一向為業界所重視,相關的專利如證號I 534338等案即是。目前業界所用之防火隔煙捲幕,固然具有阻隔火勢蔓延的效果,惟美中不足者,就是這些防火隔煙捲幕普遍存有一個大缺失,主要是因門軌中的防火隔煙捲幕通道,都是由門軌的板體向內延伸彎折所形成的通道側壁,該板體本身為金屬材質,而厚度又薄,所以該側壁的端 口即使經過磨邊處理,仍然還有銳利的邊緣,這種銳利的邊緣在該防火隔煙捲幕捲收的過程中,往往會產生切割作用,特別是在火警發生時,熱氣流一波波不間斷衝擊壓迫該防火隔煙捲幕,使該防火隔煙捲幕不斷的與該通道側壁摩擦,此時該側壁的邊緣卻猶如刀割一般,時間一久,就會造成該防火隔煙捲幕的毀損與破孔,直接影響到該防火隔煙捲幕與門軌軌道之間的氣密,導致防火隔煙效果大打折扣。 In order to prevent the fire and smoke from spreading, the airtight effect between the fireproof smoke curtain and the door rail has always been valued by the industry. Relevant patents such as the certificate number I 534338 are the case. At present, the fire-proof and smoke-proof curtains used in the industry have the effect of blocking the spread of fire. However, the inadequacy of the people is that there is a big shortage of these fire-proof and smoke-proof curtains, mainly because of the fire-proof and smoke-free curtain channels in the door rails. The plate body of the door rail extends inwardly to extend the side wall of the channel formed by bending, the plate body itself is made of metal material, and the thickness is thin, so the end of the side wall Even if the mouth is edging, there are still sharp edges. This sharp edge tends to cut during the process of winding the fireproof smoke curtain, especially when the fire occurs, the hot air is not wavered. The intermittent impact oppresses the fire-proof cigarette screen, so that the fire-proof cigarette screen is continuously rubbed against the side wall of the passage. At this time, the edge of the side wall is like a knife cut. After a long time, the fire-proof smoke screen is damaged and broken. The hole directly affects the airtightness between the fireproof smoke screen and the door rail track, which results in a significant reduction in the effect of fire and smoke.

有鑑於此,本案創作人歷經無數次研究改良後,終於完成本案之防火隔煙捲幕其門軌結構,即本案之創作目的,係在提供一可降低防火隔煙捲幕磨損之門軌結構,藉以增加防火隔煙捲幕作動的順暢性,有效阻止火勢及濃煙之蔓延者。 In view of this, after many times of research and improvement, the creator of this case finally completed the door rail structure of the fire-proof and smoke-proof curtain of this case, that is, the purpose of the creation of the case is to provide a door rail structure which can reduce the wear and tear of the fire-proof smoke-proof screen.
