Description

Technical Field

[0001] This utility model relates to the field of fireproof rolling shutter door technology, and in particular to a double-track inorganic composite fireproof rolling shutter door. Background Technology

[0002] In the field of building fire protection, fire-resistant roller shutters are widely used in various buildings as important fire-resistant partitions. Their function is to prevent the spread of fire and ensure the evacuation of personnel and the safety of property during a fire. With the continuous improvement of building safety standards, the market has placed higher demands on the performance of fire-resistant roller shutters. They not only need to possess basic fire-resistant functions but also meet higher fire resistance limits, better heat insulation effects, and more reliable stability. Inorganic composite materials, due to their high-temperature resistance and anti-aging properties, have gradually become an important direction for technological innovation in fire-resistant roller shutters. A double-track inorganic composite fire-resistant roller shutter has emerged, aiming to improve the comprehensive performance of fire-resistant partitions through structural optimization.

[0003] In existing technologies, fire-resistant roller shutters mainly come in several types. Single-layer metal curtain roller shutters achieve fire resistance by relying on the high-temperature resistance of metal materials and directly blocking flames through the metal curtain. Roller shutters with water curtain protection have an independent water supply system on the outside of the curtain, which continuously sprays water to form a water curtain to enhance the fire resistance effect. Single-layer inorganic composite material roller shutters use a single inorganic curtain structure and utilize the fire-resistant properties of inorganic materials to block the fire. Their technical principle mostly relies on a single material or external auxiliary system to achieve basic fire protection function, without targeted optimization of the heat insulation structure.

[0004] While existing single-layer inorganic composite material roller shutters offer improved thermal insulation compared to metal curtain roller shutters, their reliance on a single curtain structure and lack of effective air gap separation and composite insulation design means heat can easily be conducted directly to the unexposed side through the curtain. During a fire, their insulation performance is difficult to maintain, failing to meet the requirements of high fire resistance scenarios. This leads to a rapid increase in temperature on the unexposed side, increasing the risk of secondary fires. This limitation restricts their application in high-safety-level buildings. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a double-track inorganic composite fireproof roller shutter door, which aims to improve the problem that the heat insulation effect of the existing technology is difficult to maintain during the continuous fire and cannot meet the needs of high fire resistance limit scenarios, resulting in a rapid increase in the temperature of the unexposed surface, which easily causes the risk of secondary fire.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A double-track inorganic composite fireproof rolling shutter door includes a rolling frame, a protective frame fixedly connected to the side wall of the rolling frame, a slide rail fixedly connected to the bottom of the rolling frame, a slow-speed motor fixedly connected inside the protective frame, a rolling roller fixedly connected to the output end of the slow-speed motor, a fireproof curtain fixedly connected to the outer wall of the rolling roller, the rolling roller being rotatably connected inside the rolling frame, the fireproof curtain being slidably connected inside the slide rail, and a partition component being provided inside the fireproof curtain; The separation component includes multiple first-level separation strips and multiple second-level separation strips. One side wall of each of the multiple first-level separation strips is fixedly connected to the inner wall of the fireproof curtain, and the multiple second-level separation strips are fixedly connected to the inner wall of the fireproof curtain. Micropores are provided inside the multiple first-level separation strips and the multiple second-level separation strips. A sealing component is provided inside the fireproof curtain.

[0007] The above technical solution achieves stable lifting and lowering of the fireproof roller shutter door, provides an installation basis for the partition and sealing components, and ensures the structural integrity and operational reliability of the fireproof curtain.

[0008] Preferably, the sealing assembly includes a convex sealing strip and a concave sealing strip, the sidewall of the convex sealing strip is fixedly connected to the inner wall of the slide rail, the sidewall of the concave sealing strip is fixedly connected to the inner wall of the slide rail, and the convex sealing strip and the concave sealing strip are fitted together.

[0009] The above technical solution creates a preliminary sealing structure between the fireproof curtain and the sliding rail, effectively blocking the initial flow of smoke and heat.

[0010] Preferably, both the first and second partition strips are made of fiberglass woven tape and are arranged alternately along the width of the fireproof curtain.

[0011] The above technical solution utilizes the high temperature resistance and flexibility of fiberglass woven tape to achieve air layer separation to reduce convection, while also adapting to the rolling action of the fireproof curtain.

[0012] Preferably, the micropores are evenly distributed inside the first and second separators, and the micropores are filled with ceramic fiber insulation cotton.

[0013] The above technical solution enhances the heat insulation capacity of the separator strip by utilizing the ceramic fiber insulation cotton inside the micropores, and works synergistically with the air layer to improve the heat barrier effect.

[0014] Preferably, the convex sealing strip and the concave sealing strip are fixed to the inner wall of the slide rail by silicone rubber adhesive, and both the convex sealing strip and the concave sealing strip are made of graphite-based expansion strips.

[0015] The above technical solutions improve the stability of the connection between the sealing strip and the slide rail. The graphite-based expansion strip expands when exposed to fire, which can further fill the gap and enhance the sealing performance.

[0016] Preferably, the fireproof curtain has a multi-layer composite structure, including an outer fireproof cloth layer, a middle heat insulation layer, and an inner protective layer.

[0017] Through the above technical solutions, a multi-layered, collaborative fireproof and heat-insulating barrier is constructed by dividing the functions of the outer fireproof layer, the middle heat insulation layer, and the inner protective layer.

[0018] Preferably, the first separator and the second separator are fixed at the interlayer positions of the fireproof curtain.

[0019] The above technical solution enables the separator strips to act precisely between the layers of the fireproof curtain, strengthening the separation of the interlayer space and improving the stability of the overall thermal insulation structure.

[0020] Preferably, the first and second separators are used to separate the inner wall space of the fireproof curtain, and the interior of the fireproof curtain is filled with aerogel felt to form a heat-insulating chamber.

[0021] The above technical solutions form an independent heat insulation chamber, which, combined with the high-efficiency heat insulation properties of aerogel felt, further enhances the overall heat insulation performance of the fireproof curtain.

[0022] This utility model has the following beneficial effects: 1. In this utility model, by alternately arranging partition strip one and partition strip two along the width direction of the fireproof curtain, the air layer between the double-layer curtain is divided into multiple independent small chambers, reducing air convection within the layer. Subsequently, the micropores in the partition strip are filled with ceramic fiber insulation cotton, and the interior of the fireproof curtain is filled with aerogel felt, forming multiple heat insulation barriers. The air turbulence effect and the heat insulation material work together to weaken heat transfer, thereby effectively blocking the conduction of heat to the unexposed side during a fire, thus achieving the effect of improving heat insulation performance. This solves the problem of insufficient heat insulation of traditional single-layer inorganic curtains and inability to meet high fire resistance requirements, and improves the fire resistance stability of fireproof roller shutter doors.

[0023] 2. In this utility model, the convex and concave sealing strips are interlocked on the inner wall of the slide rail, forming a preliminary seal between the fireproof curtain and the slide rail. Subsequently, the sealing strip made of graphite-based expansion strip expands when exposed to fire, filling the gap between the curtain and the guide rail, forming a multi-path seal. This effectively blocks the flow of smoke and heat during a fire, thereby enhancing the sealing performance. This solves the problems of easy aging and poor sealing of traditional sealing strips leading to smoke leakage, and improves the smoke and fire prevention safety of the fireproof roller shutter door.

[0027] Reference Figure 1 - Figure 5 A double-track inorganic composite fireproof rolling shutter door includes a rolling frame 1, which supports the overall structure and provides a rotating mounting base for the rolling roller 6. A protective frame 2 is fixedly connected to the side wall of the rolling frame 1. The protective frame 2 protects the internal slow motor 5 from the influence of the external environment. A slide rail 3 is fixedly connected to the bottom of the rolling frame 1. The slide rail 3 guides the fireproof curtain 4 to slide stably along its interior to achieve lifting and lowering actions. A slow motor 5 is fixedly connected inside the protective frame 2. The slow motor 5 outputs power to drive the rolling roller 6 to rotate. The output end of the slow motor 5 is fixedly connected to the rolling roller 6. The rolling roller 6 is used to achieve opening and closing actions by rotating to roll up or release the fireproof curtain 4. A fireproof curtain 4 is fixedly connected to the outer wall of the rolling roller 6. The fireproof curtain 4, as a core fireproof component, is used to block the spread of fire and smoke. The rolling roller 6 is rotatably connected inside the rolling frame 1. The fireproof curtain 4 is slidably connected inside the slide rail 3. A partition component is provided inside the fireproof curtain 4 to separate the internal space of the fireproof curtain 4 and reduce air convection. The partition assembly includes multiple partition strips 7 and multiple partition strips 8. The partition strips 7 and 8 are used to divide the air layer inside the fire curtain 4 into independent small chambers to enhance heat insulation. The side walls of the partition strips 7 are fixedly connected to the inner wall of the fire curtain 4, and the partition strips 8 are fixedly connected to the inner wall of the fire curtain 4. Each partition strip 7 and partition strip 8 has micropores 9 inside. The micropores 9 are used to fill heat insulation material to enhance the heat insulation and heat resistance of the partition strips. A sealing assembly is provided inside the fire curtain 4. The sealing assembly is used to enhance the sealing between the fire curtain 4 and the slide rail 3 to prevent smoke from flowing through.

[0028] Reference Figure 1 - Figure 5 The sealing assembly includes a convex sealing strip 11 and a concave sealing strip 12. The convex sealing strip 11 and the concave sealing strip 12 enhance the sealing between the fire curtain 4 and the slide rail 3 through their interlocking structure. The sidewall of the convex sealing strip 11 is fixedly connected to the inner wall of the slide rail 3, and the sidewall of the concave sealing strip 12 is also fixedly connected to the inner wall of the slide rail 3. The interlocking of the convex sealing strip 11 and the concave sealing strip 12 forms a preliminary seal to prevent smoke from flowing through. Separator strip 7 and separator strip 8 are both made of fiberglass woven tape. The fiberglass woven tape has high temperature resistance and flexibility to adapt to the rolling action of the fire curtain 4. They are alternately arranged along the width of the fire curtain 4 to separate internal air layers and reduce convection. Micropores 9 are evenly distributed inside separator strip 7 and separator strip 8. The micropores 9 are filled with ceramic fiber insulation cotton, which enhances the heat insulation and heat resistance of the separator strips. The convex sealing strip 11 and the concave sealing strip... 12 is fixed to the inner wall of the slide rail 3 by silicone rubber adhesive. The silicone rubber adhesive improves the stability of the connection between the sealing strip and the slide rail 3. Both the convex sealing strip 11 and the concave sealing strip 12 are graphite-based expansion strips. The graphite-based expansion strips can expand and fill the gaps to strengthen the seal when exposed to fire. The fire curtain 4 is a multi-layer composite structure, including an outer fireproof cloth layer, a middle heat insulation layer and an inner protective layer. The outer fireproof cloth layer is used to directly block flames, the middle heat insulation layer is used to block heat transfer, and the inner protective layer is used to protect the inner structure. The first separator 7 and the second separator 8 are fixed at the interlayer positions of the fire curtain 4, and act precisely between each layer to strengthen the space separation effect. The first separator 7 and the second separator 8 are used to separate the inner wall space of the fire curtain 4. The fire curtain 4 is filled with aerogel felt 10. The aerogel felt 10 has high-efficiency heat insulation performance and forms a heat insulation chamber to further improve the overall heat insulation effect.

[0029] Working principle: The slow-speed motor 5 fixed inside the protective frame 2 starts and outputs power, which drives the winding roller 6 to rotate inside the winding frame 1. When the winding roller 6 rotates, the fireproof curtain 4 fixed on its outer wall is wound up or released, thereby driving the fireproof curtain 4 to slide along the slide rail 3 fixed at the bottom of the winding frame 1 to achieve the lifting action. During the sliding process, the two sides of the fireproof curtain 4 are in close contact with the convex sealing strip 11 and concave sealing strip 12 on the inner wall of the slide rail 3. The convex sealing strip 11 and concave sealing strip 12 form a preliminary seal through the interlocking of the convex sealing strip 11 and concave sealing strip 12. When a fire occurs, the internal partition components of the fire curtain 4 begin to function. The partition strips 7 and 8 are alternately arranged along the width of the fire curtain 4 and fixed at the interlayer position, which divides the air layer between the double curtain surfaces into multiple independent small chambers, reducing air convection within the layers. At the same time, the ceramic fiber insulation cotton filled in the micropores 9 evenly distributed inside the partition strips 7 and 8 works synergistically with the aerogel felt 10 filled inside the fire curtain 4 to form multiple heat insulation barriers. The heat transfer is weakened by the air turbulence effect. In addition, the convex sealing strip 11 and concave sealing strip 12 on the inner wall of the slide rail 3 are graphite-based expansion strips that expand when exposed to fire, further causing the gap between the filling curtain surface and the guide rail to form a multi-path seal, effectively blocking the transfer of heat and smoke.
