Description

Indoor fire-proof rolling curtain structure

Technical Field

The application relates to the technical field of rolling doors, in particular to an indoor fireproof rolling shutter structure.

Background

Present architectural design, plan, must consider the security when the conflagration takes place, in order to prevent that dense cigarette from scurrying indiscriminately, so the inside cigarette accuse system that can install additional of building, in order to distinguish the dense cigarette that produces when the conflagration takes place and separate, and equipment such as the fire prevention shutter is shielded in main application of current cigarette accuse system, should hide the fire prevention shutter device of cigarette benefit and roll up when not using, its usable reel of roll up of curtain comes the roll-up box of installing in ceiling department, when treating the conflagration emergence, cooperate automatic sensing system again to put down the fire prevention in good time and roll up the curtain, with the stretching of separation intensity of a fire, effectively ensure personnel's safety and evacuation route, and then reduce harm, the damage that the conflagration brought.

After the fire-proof rolling curtain in the prior art is put down, a gap is often formed between the side edge of the fire-proof rolling curtain and the embedded door rail, and after the fire-proof rolling curtain is closed, a gap is also often formed between the end part of the fire-proof rolling curtain close to the ground and the ground; the fire area generates a large amount of hot air due to combustion, so the air pressure in the fire area is higher than that in the area which is not spread by fire, and the two side surfaces of the fire-proof roller shutter can shake, tear and the like due to different pressures.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: if the conditions such as shaking and tearing are too severe, the side edge of the fire-proof rolling curtain can be separated from the door rail, and a larger gap is generated between the fire-proof rolling curtain and the door rail, so that dense smoke can flow to the other side of the rolling curtain through the gap at the side part and the gap at the bottom, and the fire-proof performance of the rolling curtain is influenced.

SUMMERY OF THE UTILITY MODEL

When closing in order to improve the fire prevention shutter body, the bottom gap between lateral part gap between the AND gate rail, and the ground influences the fire prevention performance's of fire prevention shutter problem, and this application provides an indoor fire prevention shutter structure.
