Description

Curtain fire curtain in the curtain

Technical field

The utility model relates to a kind of roller shutter of making the water-fog type fire resistance rolling shutter door.Belong to the extinguisher field.

Background technology

The roller shutter of existing water-fog type fire resistance rolling shutter door mostly is made of steel band and the number of metal curtain plate that is installed on the steel band, puts down roller shutter with the partition scene of a fire by controlling organization during breaking out of fire, and to the temperature of roller shutter water spray with the reduction roller shutter.The shortcoming of this roller shutter is that its roller shutter is a monolithic roller shutter, put down roller shutter after impersonal force can open certainly, the personnel that fail to leave early the scene of a fire are hindered by roller shutter and can't go out outdoors, unfavorable fire goods and materials in advance shift and personnel's escape.

Summary of the invention

The purpose of this utility model is the above-mentioned shortcoming that overcomes existing fire curtain, provide a kind of can effectively cut off the scene of a fire, can also be for curtain fire curtain in the curtain of personnel's turnover.

Realize in the curtain of the utility model purpose that the curtain fire curtain comprises by steel band and is installed in the curtain face that the some curtain plates on the steel band constitute, the lower position of described curtain face be provided with one with the little curtain face of curtain face hinge joint, on the relative side of two curtain faces, be provided with magnet.When roller shutter is put down in breaking out of fire, under the effect of the magnet between two curtain faces, make little curtain face and whole roller shutter remain an integral body well, play the effect that cuts off the scene of a fire; The personnel of being closed in the inside, the scene of a fire can start little curtain face with the absorption affinity of making every effort to overcome the clothes magnet and go out to the roller shutter outside, the little curtain face of hinge joint is sagging return under the effect of deadweight, by the magnet between two curtain faces little curtain face suction is connected to big curtain face and makes whole roller shutter remain an integral body well.

Compared with the aforementioned existing similar products, the utility model has the advantages that putting down roller shutter cuts off also to have behind the scene of a fire for fire goods and materials in advance and shift and the function of personnel's escape.Little curtain face self-return reliability height has kept the globality of roller shutter well and can not influence the cutting function of roller shutter.Can be widely used in existing various fire resistance rolling shutter door.

Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
