Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, and in particular to a smoke-proof and fire-fighting roller shutter for shopping malls. Background Technology

[0002] Smoke-proof fire-resistant roller shutters for shopping malls are important fire-fighting facilities installed inside malls to block the spread of smoke and control the spread of fire during a fire. Their curtains are usually made of metal, possessing good strength and fire resistance, which can slow the spread of smoke within the mall, buying valuable time for evacuation and fire rescue. Confining the impact of a fire to a localized area and minimizing casualties and property damage is a key line of defense for ensuring the fire safety of shopping malls.

[0003] The main body of a roller shutter door consists of curtain panels that are hinged together in series. It can be suspended vertically along tracks on both sides or rolled up freely. To facilitate bending and rolling, there are gaps between adjacent curtain panels, lacking a sealing structure, allowing some smoke to pass through these gaps. Examples include the patented inward-locking double-arc fireproof roller shutter panel with publication number CN2290279Y, and a wind-pressure resistant fireproof roller shutter panel with publication number CN206409168U. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art mentioned above and to provide a smoke-proof fire-fighting roller shutter door for shopping malls.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A smoke-proof fire-fighting roller shutter door for shopping malls includes several curtain panels that are hinged together in sequence. Each curtain panel has an upper hook and a lower hook at its upper and lower ends, and adjacent curtain panels are hinged together through the upper hook and the lower hook. A sealing strip is provided on the inner side of the upper hook. When adjacent curtain panels are suspended vertically, the end of the lower hook abuts against the sealing strip.

[0007] Furthermore, a support strip is connected to the inner side of the upper hook, and the sealing strip is connected to one side of the support strip.

[0008] Furthermore, the edge of the end face of the curtain panel is provided with a brush.

[0009] Furthermore, the curtain panel is provided with weight-reducing holes, which extend to both ends of the curtain panel.

[0010] Furthermore, the weight-reducing holes are filled with heat-insulating material.

[0011] Furthermore, the insulation material is rock wool.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention features a sealing strip on the inner side of the upper hook joint of the curtain panel. When the curtain panel is unfolded and suspended, the end of the lower hook joint abuts against the sealing strip to seal the gap between the curtain panels, reducing smoke passing through the gap and improving the smoke isolation effect. The sealing strip provides one-way limitation for the hinge of the curtain panel and does not affect the winding of the curtain panel. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Specific embodiments of the smoke-proof fire-fighting roller shutter door for shopping malls provided by this utility model:

[0022] Please see Figure 1-5 The smoke-proof fire-fighting roller shutter door for shopping malls includes several curtain panels 1 that are hinged together in sequence. The upper and lower ends of the curtain panel 1 have an upper hook part 2 and a lower hook part 3, respectively. Both the upper hook part 2 and the lower hook part 3 are curved in an arc shape. Adjacent curtain panels 1 are hinged by the upper hook part 2 and the lower hook part 3 extending into each other. This allows the curtain panels 1 to be hung vertically and rolled up freely.

[0023] Since the curtain panel 1 and its upper hook part 2 and lower hook part 3 are all made of metal, the sealing of the hinge part is not good. In the traditional structure, there are gaps between the curtain panels 1, which allows some smoke to pass through.

[0024] In this embodiment, a sealing strip 4 is provided on the inner side of the upper hook part 2. The sealing strip 4 is made of rubber and has a certain elastic deformation capability when compressed. Specifically, a support strip 5 is connected to the inner side of the upper hook part 2. The support strip 5 is made of metal and is integrally connected to the upper hook part 2. The sealing strip 4 is adhered to one side of the support strip 5.

[0025] When adjacent curtain panels 1 are suspended vertically, the end of the lower hook joint 3 abuts against the sealing strip 4. Under the action of the weight of the curtain panel 1, the curtain panel 1 is in a vertical hanging state, so that the lower hook joint 3 of the upper curtain panel 1 is tightly abutted against the sealing strip 4, compressing the sealing strip 4 and causing the sealing strip 4 to produce a certain compression deformation, promoting the sealing strip 4 to make close contact with the lower hook joint 3, blocking the gap, achieving a seal, and thus reducing the gap between the curtain panels 1.

[0026] The curtain panel 1 has weight-reducing holes 7 extending to both ends of the curtain panel 1, and the weight-reducing holes 7 are filled with heat-insulating material 8. The heat-insulating material 8 filling the weight-reducing holes 7 in the curtain panel 1 can reduce the weight of the curtain panel 1, reduce the winding load, and effectively block heat transfer.

[0027] In this embodiment, the insulation material 8 is rock wool. In some other embodiments, aluminosilicate refractory fiber cotton, perlite, or phenolic foam can be used instead of rock wool.

[0028] The end of the curtain panel 1 moves along the vertical tracks on both sides of the roller shutter door. There is a gap between the end of the curtain panel 1 and the track, which also allows some smoke to pass through.

[0029] In this embodiment, a plastic brush 6 is provided on the edge of the end face of the curtain panel 1. Specifically, dense brushes 6 are provided on the end faces of the curtain panel 1 and its upper hook part 2 and lower hook part 3, that is, dense brushes 6 are evenly provided on the end face of the metal part of the curtain panel 1. The outer end of the brush 6 ends at the inner side of the track, blocking the gap between the curtain panel 1 and the track, which can significantly reduce the passage of smoke.

[0030] Although the brush 6 is in contact with the inner side of the track, it can be bent and deformed with little resistance, so it has minimal impact on the movement of the curtain panel 1 in the track and can reduce the friction between the curtain panel 1 and the track.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
