Description

Technical Field

[0001] This utility model relates to the field of smoke curtain design, specifically to an overlapping single-track fireproof roller shutter structure. Background Technology

[0002] Smoke curtains are mainly used in high-rise or super high-rise shopping malls, office buildings, and warehouses. They effectively block the horizontal flow of smoke under the building's ceiling, thereby improving smoke extraction within smoke control zones. Existing single-track fireproof roller shutters use a single roller shaft, resulting in large deflection and limiting their span; large spans cannot meet national standard deflection requirements.

The first and second mounting plates are installed in corresponding positions. Two rollers, a first roller and a second roller, are provided between the first and second mounting plates. The first and second rollers are respectively connected to a drive device. A plurality of first fireproof roller shutter curtains are wound around the first roller along its length. A second fireproof roller shutter curtain is overlapped between two adjacent first fireproof roller shutter curtains. The second fireproof roller shutter curtain is wound on the second roller. The first and second fireproof roller shutter curtains are connected to the same base at the bottom.

[0006] The base is slidably connected to the guide rail on both sides.

[0007] Preferably, multiple support members are connected to the first and second reels.

[0008] Preferably, the support member includes a support plate and a top wheel, and the support plate has a through hole;

[0009] Multiple top rollers are provided along the circumferential edge of the through hole, and the first or second spool passes through the through hole and is supported by the rolling of the top rollers.

[0010] Preferably, the base is a U-shaped clamp structure.

[0011] Preferably, the second fireproof roller shutter fabric overlaps and interlocks with the first fireproof roller shutter fabric.

[0012] Preferably, the driving device is a fireproof motor, which is fixedly connected to the first mounting plate;

[0013] The fireproof motor is connected to the controller, and the controller is connected to the button box.

[0014] Preferably, a temperature-controlled release device is installed below the second reel.

[0015] Preferably, a smoke-proof device is installed on the side of the guide rail.

[0016] Preferably, both the first and second fireproof roller shutter fabrics are inorganic fireproof fabrics.

[0017] In summary, the beneficial effects of this utility model are as follows: The simultaneous winding and unwinding of the first and second fire-resistant roller shutter curtains using multiple rollers, with overlapping sections, effectively avoids gaps between adjacent curtains, achieving large-span smoke protection and meeting national standard deflection requirements. Furthermore, the single-rail structure ensures stable winding of both the first and second fire-resistant roller shutter curtains. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] See Figures 1-6 As shown, this utility model provides an overlapping single-track fireproof roller shutter structure, including a first mounting plate 3, a second mounting plate 4, and a guide rail 15. The first mounting plate 3 and the second mounting plate 4 are installed in corresponding positions. Two rollers, a first roller 5 and a second roller 6, are provided between the first mounting plate 3 and the second mounting plate 4. The first roller 5 and the second roller 6 are respectively connected to a drive device, preferably connected by a chain 11 and a sprocket drive mechanism. A plurality of first fireproof roller shutter curtains 1 are wound around the first roller 5 along its length direction. A second fireproof roller shutter curtain 2 overlaps between two adjacent first fireproof roller shutter curtains 1. The second fireproof roller shutter curtain 2 is wound on the second roller 6. The first fireproof roller shutter curtains 1 and the second fireproof roller shutter curtain 2 can be rolled up separately. The second fireproof roller shutter curtain 2 overlaps with the first fireproof roller shutter curtain 1, and the overlap width effectively avoids gaps between adjacent fireproof roller shutter curtains. Both the first fireproof roller shutter curtain 1 and the second fireproof roller shutter curtain 2 are inorganic fireproof fabrics. The first fireproof roller shutter curtain 1 and the second fireproof roller shutter curtain 2 are connected to the same base 10 at the bottom, and the base 10 has a U-shaped clamping structure. This clamps the bottom of the fireproof roller shutter curtains. The two sides of the base 10 are slidably connected to the guide rails 15.

[0029] In a preferred embodiment of this case, a plurality of support members 7 are connected to the first scroll 5 and the second scroll 6.

[0030] refer to Figure 6As shown, the support member 7 includes a support plate 701 and top rollers 702. The support plate 701 has a through hole. Multiple top rollers 702 are arranged along the circumferential edge of the through hole. The first reel 5 or the second reel 6 passes through the through hole and is supported by the top rollers 702 in a rolling manner. By supporting the middle of the reel through the support member 7, the top rollers 702 can support the reel and maintain its stability when it is being wound.

[0031] Preferably, the driving device is a fireproof motor 12, which is fixedly connected to the first mounting plate 3; the fireproof motor 12 is connected to the controller 8, and the controller 8 is connected to the button box 9.

[0032] Furthermore, a temperature-controlled release device 13 is installed below the second roller 6. When the temperature around the temperature sensing element of the release device reaches 73±0.5℃, the release device is activated, and the roller shutter should descend and close by its own weight.

[0033] Furthermore, a smoke-proof device 14 is installed on the side of the guide rail 15.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
