Fireproof and smoke-proof curtain curtain door airtight structure

The present invention relates to a door rail airtight structure of a fireproof smoke-proof roll screen, and particularly relates to an airtight structure capable of effectively sealing a gap between a fireproof smoke-proof roll screen and a door rail, thereby preventing a fire and a smoke spreader.

According to the general fire, the thick smoke in the fire is densely covered, and it will flow through various pipes. It is easy to form a chimney effect, which will cause serious damage to people and property. Therefore, when building a fire protection facility, the building will be planned. For a plurality of fire zones, and by the barrier of fire and smoke insulation devices in each fire zone, it can effectively block the spread of fire in the event of fire, to ensure that the fire field no longer spreads; at the same time, in order to consider its usual movements The use efficiency of the line and the activity space will use a large number of fire-proof smoke-proof curtains with fire-proof function. The benefits are nothing more than the usual hiding, which does not affect the use of space, and can be lowered in an emergency to prevent the fire. Spreading; but the fly in the ointment is that after the fire-proof cigarette screen is lowered, the side of the fire can not completely conform to the track on the wall, so that there is no small gap between the fire-proof cigarette screen and the door rail track. These voids often form a passage for the flame tongue and the turbulent flow of smoke, thus greatly reducing the effect of the smoke.

In order to solve this deficiency, the industry is actively researching and improving, such as the patent certificate number M452220, M480588 and other previous cases, but the patents are only focused on the door rail track knot. The improvement of the structure, while neglecting the key to truly play the airtightness of the gap, must rely on the fireproof smoke-proof curtain with a moderately soft material to truly block the occurrence of the gap, but the industry has not yet solved it satisfactorily. Technical solution; in addition, the structure of the general door rail track can not be designed too complicated, otherwise the difficulty and cost of forming processing will be higher, but if the structure is not accurate enough, it is not easy to seal to prevent the flow of hot air, so how to overcome these problems, It has always been the technical bottleneck of the industry's desire to break through.

In view of this, after many times of research and improvement, the creator of this case finally completed the air-tight structure of the door and rail 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 gap between the fire-proof smoke-proof curtain and the door rail.
