Description

Technical Field

[0001] This utility model belongs to the field of engineering technology, specifically a synchronous lifting linkage device for an irregularly shaped fireproof roller shutter. Background Technology

[0002] The landscape atrium of the large commercial complex features a gradually changing shape and circulation design on each floor, giving people a sense of novelty. The irregular curved beams and the different placement on each floor increase the difficulty of installing the fireproof roller shutters. The irregular cantilevered atrium is layered, with each floor having an irregular curve and a large number of irregular folded plate hanging beam nodes. The processing, installation, and operation of the irregular fireproof roller shutters have high requirements.

[0003] Fire-resistant roller shutters include steel fire-resistant roller shutters and inorganic fabric fire-resistant roller shutters. In building design, inorganic double-track, double-curtain inorganic fabric fire-resistant roller shutters are often used to divide fire zones. However, for irregularly shaped buildings, especially the atriums of large commercial complexes, traditional fire-resistant roller shutters attached to rollers are no longer sufficient. Excessive roller length leads to inconsistent left and right running heights and drooping in the middle of the shutter during operation. Traditional rollers use electronic drive to roll the inorganic fabric fire-resistant roller shutter onto their surface. Because the rollers are straight, they cannot meet the needs of irregular openings, requiring passageway width. Dividing the shutter into several small units increases the number of steel columns and control motor systems, increasing costs and inevitably affecting the overall aesthetics of the atrium.

[0004] Currently, irregularly shaped fire-resistant roller shutters on the market use external rollers and mechanical linkage to drive the shutter's up-and-down folding and lifting mechanism. After lifting, the top often fails to seal properly with the structure, resulting in poor fire and smoke isolation. Furthermore, irregularly shaped fire-resistant roller shutters are restricted from use in building fire compartmentation due to their inability to meet self-weight closing requirements and insufficient reliability. In the event of a fire, the exposed drive mechanism of the fire-resistant roller shutter is highly susceptible to damage from open flames, hot air, and high-temperature smoke. It may also fail to operate or break during operation when the fire-resistant roller shutter needs to be used for evacuation. Therefore, there is an urgent need for a synchronous lifting linkage device for irregularly shaped fire-resistant roller shutters that can meet self-weight closing requirements while being safe, reliable, and fire-resistant, and undamaged during the initial rescue phase of a fire. Summary of the Invention

[0005] To address the problem that existing irregularly shaped fireproof roller shutters cannot meet the self-weight closing function and cannot effectively block smoke, this utility model provides a synchronous lifting linkage device for irregularly shaped fireproof roller shutters.

[0006] This utility model adopts the following technical solution: a synchronous lifting linkage device for an irregularly shaped fireproof roller shutter, comprising: An irregularly shaped lower steel component, wherein the shape of the irregularly shaped lower steel component is consistent with the shape of the decorative roller blind; An irregularly shaped upper steel section assembly, the shape of which is consistent with that of the irregularly shaped lower steel section assembly, and is positioned directly below the irregularly shaped lower steel section assembly; A roller shutter door body, wherein the roller shutter door body is connected between the irregular lower steel profile assembly and the irregular upper steel profile assembly; Lifting device, the lifting device being used to lift the roller shutter door body; The controller controls the lifting device and is signal-connected to the smoke detector and the temperature control release device. When the smoke detector sends an alarm signal or the temperature control release device reaches the specified temperature, the roller shutter door will automatically descend.

[0007] In some embodiments, the roller shutter door body is provided in two sets, symmetrically arranged on both sides of the irregular lower steel section assembly and the irregular upper steel section assembly.

[0010] In some embodiments, two fixed pulleys are installed inside a metal fireproof box. The fixed pulleys are concave steel wheels with a wheel groove width of 160mm and a diameter of 100mm.

[0011] In some embodiments, a passive wheel assembly is further provided on the pipe, the passive wheel assembly comprising: A central steel support frame, which is fixed to a concrete structure; Multiple pulleys are installed inside a central steel support, and pipes pass between the multiple pulleys.

[0012] In some embodiments, a lower sealing plate is also included, which is disposed at the bottom of the irregularly shaped lower steel assembly.

[0013] In some embodiments, the irregular lower steel section and the irregular upper steel section are formed by bending 50×50×4mm square tubes in sections, and 50×50×3mm square tube reinforcing components are arranged laterally.

[0014] In some embodiments, the lower sealing plate is made of 3mm thick aluminum plate, with aluminum alloy U-shaped reinforcing ribs at the rear.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model enables fireproof roller shutters with irregular shapes such as arc, circle, and zigzag to be integrated into a single irregular shape.
