Fireproof roll door door rail airtight structure

The present invention relates to a door rail airtight structure of a fireproof rolling door, and particularly relates to an airtight structure capable of effectively sealing a gap between a fireproof curtain and a door rail, thereby preventing a spreader of fire.

In the event of a general fire, the dense smoke will use various pipes to smash around, and it is easy to form a chimney effect and cause serious damage to people and property. Therefore, when building a fire protection facility, the building will be planned as a plurality of fire zones. And by blocking the fire and smoke insulation device 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 the use of the usual moving and moving space Benefits, a large number of fire-proof curtains with fire-proof function will be used. Its benefits are nothing more than the usual use of hidden space that does not affect the use of space. In an emergency, it can be lowered in time to prevent the spread of fire. However, the only problem is the fire prevention. After the curtain is lowered, the side of the screen does not completely fit on the track on the wall. There is often a small gap between the fire curtain and the track, which results in a significant reduction in the smoke-free effect. Based on the above deficiency, the industry is Active research and development, but still can not find better structures and devices to solve the aforementioned shortcomings.

In view of this, after many times of research and improvement, the creator of this case finally completed the airtight structure of the fire door of the case, that is, the purpose of the creation of the case is to provide a door rail that can seal the gap between the fireproof curtain and the door rail. Airtight structure to effectively prevent The hot air is scurrying, which prevents the spread of the fire.

In order to achieve the above-mentioned purpose of the present invention, the fireproof roll door of the present invention has a door rail airtight structure, which is provided with a door rail on each side of the bottom of a roll box, and the roll box is provided with a reel which is wound a fireproof rolling screen, the lower end of the fireproof rolling screen is fixed with a swinging seat, and the utility model is characterized in that: a sleeve is arranged on both sides of the fireproof rolling screen, and the sleeve is internally sleeved with a guiding rod and is disposed on the door a guiding passage in the base of the door rail, so as to guide the sleeve to seal the gap between the fireproof curtain and the guiding passage when the hot airflow presses the fireproof curtain, thereby effectively preventing the hot airflow from colliding, Then stop the spread of the fire.

Please refer to the first, second and third figures. The fireproof roll door of the present invention has a door rail airtight structure, which is provided with a door rail 4 on both sides of the bottom of a roll box 1, and a roll door 1 is provided therein. a reel 2, the reel 2 is wound with a fireproof curtain 3, and the lower end of the fireproof reel 3 is fixed with a lower seat 32, wherein each side of the fire reel 3 is provided with a sleeve 31, The sleeve 31 is internally sleeved with a guiding rod 44, and is disposed on a guiding passage 42 of the door rail 4 in the door rail base 41, so as to guide the sleeve 31 when the hot air flow presses the fireproof curtain 3. The gap between the fire curtain 3 and the guiding passage 42 is effectively prevented from colliding with the hot air flow, thereby preventing the spread of the fire.

The guiding channel 42 is formed by a corresponding side wall 43 of the door rail 4 to form a channel. The guiding channel 42 includes an inlet section 421 of the front end and a V-shaped section 422 of the rear end. Section 421 is a front wide and a narrow pass The V-shaped section 422 is a channel of a front narrow rear width.

With the composition of the above structure, when the fire alarm 3 is released, one side of the fireproof curtain 3 is pressed by the hot airflow, and the bundle 31 in the side rails 4 is pulled to make the bundle The sleeve 31 is guided inwardly along the V-shaped section 422 of the guiding passage 42 to finally seal the gap between the fireproof curtain 3 and the guiding passage 42 to effectively prevent the hot air flow from being scrambled, thereby preventing the fire. spread.

In summary, the present invention uses a hot air flow to press a side of the fireproof curtain, and the sleeve that is pulled in the door rail is displaced inwardly to seal the gap between the fireproof curtain and the guiding passage in time. It effectively prevents the hot air from colliding and prevents the spread of the fire. Therefore, this creation is unique to the industrial utilization, novelty and progressive requirements of the new patent.

The specific embodiments set forth in the present disclosure are merely for convenience of explanation of the technical content of the present invention, and the present invention is not limited to the above embodiments, and does not exceed the spirit of the present invention and the following patent application scope. In the case of the implementation of the various changes, still belongs to the scope of this creation.
