Fireproof curtain plate door structure

Abstract

The invention relates to a fireproof curtain plate door structure. The door structure comprises a fireproof curtain plate door main body formed by at least two curtain plates, a slide limiting part for preventing the curtain plates from sliding, and a driving part for driving the curtain plates to slide. A telescoping cooperation structure which is capable of sliding in a reciprocating manner is formed between adjacent curtain plates. According to the invention, problems of inconvenient opening and closing, proneness to break down and poor working reliability of a fireproof door caused by big thickness and weight of a current curtain plate are solved; the door structure is advantaged by simple structure, easy manufacturing, wide application, easy opening and closing and high working reliability; and the door structure is mainly used for manufacturing a fireproof curtain plate door of a building.

Description

technical field [0001] The invention relates to a fireproof and insulating door used in various buildings, in particular to a fireproof curtain door structure. Background technique [0002] At present, the fireproof and insulating doors used in various buildings, especially warehouses, basements, garages, shopping malls, etc., are generally electric rolling doors. The overall curtain door structure of the roll, the adoption of the rolling shutter structure, makes the thickness of the rolling shutter panel very limited. When it is used as a high-strength protective door or a fire-proof insulation door, it is necessary to increase the thickness Thickness, but if the shutter curtain is too thick, it will not be able to coil, even if it can be coiled barely, it will fail because it is easy to get stuck. It is necessary to expand the rolling space of the rolling door on the top of the lifting guide rail of the rolling door to a large size. The heavy rolling of the rolling door w...

[0002] At present, the fireproof and insulating doors used in various buildings, especially warehouses, basements, garages, shopping malls, etc., are generally electric rolling doors. The overall curtain door structure of the roll, the adoption of the rolling shutter structure, makes the thickness of the rolling shutter panel very limited. When it is used as a high-strength protective door or a fire-proof insulation door, it is necessary to increase the thickness Thickness, but if the shutter curtain is too thick, it will not be able to coil, even if it can be coiled barely, it will fail because it is easy to get stuck. It is necessary to expand the rolling space of the rolling door on the top of the lifting guide rail of the rolling door to a large size. The heavy rolling of the rolling door will put a lot of pressure on its supporting parts, and the use span will also be affected. Therefore, its disadvantage is that the curtain When the board is too thick, it is not easy to coil, and it is easy to cause faults such as jamming, the smoothness of coiling is poor, the weight of the curtain is heavy, it is difficult to support, the working reliability is poor, and the span of the fire door is greatly limited

Chinese utility model patent CN203334870U discloses a lift-type curtain door structure. The curtain door involved in it is formed by arranging several curtain panels up and down along the slide rails. The contact surface between the curtain panels is an inclined surface. Under the action of the lifting drive parts, each curtain panel will be lifted to the place where the top curtain panel stays at the guide plate in turn. When the curtain panel door needs to be closed, each curtain panel will automatically slide down along the guide rail in turn under the action of gravity to form a closed fireproof door. The adoption of this structure also makes the top of the door take up more space. If the curtain panels are thicker, the cumulative total weight of each curtain panel is larger, and the volume occupied by stacking is also larger. The inclined contact surface will also reduce the sliding smoothness of each curtain plate, and the working reliability will be affected

Therefore, its disadvantages are that the top takes up a lot of space, the total weight is large, the sliding smoothness is reduced, the span of making fire doors is greatly limited, and the working reliability is not ideal.
