Description

Technical Field

[0001] This application relates to the field of fireproof rolling shutter door technology, and in particular to a heat-insulated fireproof rolling shutter door. Background Technology

[0002] Roller shutters (also known as roller blinds) are doors consisting of multiple articulated door panels linked together, which rotate up and down around a central axis within fixed tracks. Roller shutters are suitable for commercial storefronts, garages, shopping malls, hospitals, factories, mines, and other public places or residences.

[0003] Previously, roller shutters were only used for security purposes. However, with social development, people's awareness of their own and environmental safety has been increasing. As a result, most roller shutters have also developed fireproof and heat-insulating features.

[0004] In existing technologies, methods to improve the fire resistance and heat insulation of roller shutters include using inorganic fiber cloth for the door curtain, employing a double-curtain, double-track design, or a single-curtain, single-track design with water spray protection, in order to meet national standards for fire-resistant roller shutter insulation. However, the double-curtain, double-track design occupies a significant amount of space due to the wider track, while the water spray protection method requires additional water pipes, increasing installation costs.

[0005] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0006] Therefore, it is necessary to provide a heat-insulated and fire-resistant roller shutter door that can be single-tracked, single-curtained, and does not require a water spray system.

[0007] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0008] A heat-insulated and fire-resistant roller shutter door, comprising:

[0009] Box components;

[0010] The guide rail assembly is connected to the case assembly; and

[0011] The curtain assembly is connected to the box assembly at the top and located inside the guide rail assembly on both sides. It can be driven by the box assembly to be stored and unfolded along the extension direction of the guide rail assembly, and includes several curtain components that are rotatably connected end to end.

[0012] The door curtain component includes a first door curtain piece and a second door curtain piece connected to the back of the first door curtain piece. An accommodating space is formed between the first door curtain piece and the second door curtain piece, and the accommodating space is suitable for filling with fireproof and heat-insulating filler.

[0013] Furthermore, the middle part of the second curtain piece is recessed to form a first groove on the side away from the first curtain piece;

[0014] The first curtain piece is bent towards the second curtain piece on both sides to form a first bending portion. When the first curtain piece and the second curtain piece are connected, the bending portion is held in place on the side wall of the first groove.

[0015] Furthermore, one side of the first curtain component has a first protrusion extending outward, and the other side has a second protrusion extending outward. When two adjacent curtain components are connected, the bottom of one of the first protrusions can be connected to the top of the other second protrusion.

[0016] Furthermore, the side wall of the first curtain component located below the first protrusion is recessed inward to form a first mounting groove, and a first barrier strip is installed in the first mounting groove. When two adjacent curtain components are connected, the barrier strip can abut against the side of the second protrusion.

[0017] Furthermore, the top of the second protrusion is recessed inward to form a second mounting groove, and a second barrier strip is installed in the second mounting groove. The second barrier strip can abut against the bottom of the first protrusion.

[0018] Furthermore, the second curtain component has a first C-shaped opening formed by bending one end of the first protrusion toward the first protrusion, and a second C-shaped opening formed by bending one end of the second curtain component away from the second protrusion. The first C-shaped opening and the second C-shaped opening of two adjacent curtain components are rotatably connected.

[0019] Furthermore, the fireproof and heat-insulating filler is aluminum silicate.

[0020] Furthermore, along the width direction of the curtain component, one or more layers of aluminum foil are disposed within the fireproof and heat-insulating filler.

[0021] Furthermore, the case assembly includes a frame member connected to the guide rail assembly, a case plate covering the frame member, and a roll member disposed within the frame member;

[0022] The top of the curtain assembly is connected to the roller component, and the rotation of the roller component can cause the curtain assembly to rise or fall.

[0023] Furthermore, the roller component includes a main shaft connected to the drive component and an auxiliary shaft disposed diagonally below the main shaft. The curtain assembly overlaps the auxiliary shaft, and the auxiliary shaft can guide the curtain assembly to the slot of the guide rail assembly.

[0024] Compared with the prior art, the heat-insulating and fireproof roller shutter door of this application is provided with a housing assembly, a guide rail assembly connected to the housing assembly, and a curtain assembly connected to the housing assembly at the top and located in the guide rail assembly on both sides. The curtain assembly can be driven to be stored and unfolded by the housing assembly along the extension direction of the guide rail assembly. It includes several curtain parts that are rotatably connected end to end. The curtain part includes a first curtain piece and a second curtain piece connected to the back of the first curtain piece. An accommodating space is formed between the first curtain piece and the second curtain piece. The accommodating space is suitable for filling with fireproof filler. Thus, by filling the middle of the curtain part with fireproof and heat-insulating filler, a single curtain and single track can meet the national standard testing requirements, and there is no need to add water spray protection. This saves installation space and reduces installation costs.

[0036] Example 1

[0037] Please see Figures 1 to 4 This application provides a heat-insulating and fireproof roller shutter door, including a housing assembly 1, a curtain assembly 3, and a guide rail assembly 2. The guide rail assembly 2 is connected to the housing assembly 1 and is used to allow the curtain assembly 3 to move along the extension direction of the guide rail assembly 2. The top of the curtain assembly 3 is connected to the housing assembly 1, and the two sides are located inside the guide rail assembly 2. Under external force, it can be driven by the housing assembly 1 to be stored and unfolded along the extension direction of the guide rail assembly 2, thereby meeting the user's protection needs for the door head installed on the roller shutter door.

[0038] The curtain assembly 3 includes several curtain components that are rotatably connected end to end. Each curtain component includes a first curtain piece 31 and a second curtain piece 32 connected to the back of the first curtain piece 31. An accommodating space 4 is formed between the first curtain piece 31 and the second curtain piece 32. The accommodating space 4 is suitable for filling with fireproof filler. Thus, by filling the middle of the curtain component with fireproof and heat-insulating filler, a single curtain and a single track can meet the national standard testing requirements without the need for additional water spray protection. This saves installation space and reduces installation costs.

[0039] Specifically, in this embodiment, the fireproof and heat-insulating filler is aluminum silicate. Aluminum silicate itself is a non-combustible material with high fire resistance. It remains stable under high-temperature environments, does not burn or support combustion, and effectively prevents the spread of fire. Furthermore, aluminum silicate has excellent heat insulation properties. Its low thermal conductivity effectively reduces heat transfer and minimizes the impact of heat on surrounding objects, thus meeting national standard testing requirements without the need for a water spray system. Simultaneously, aluminum silicate has good chemical stability, is resistant to acid and alkali corrosion, and does not easily react chemically with other substances. It maintains stable performance under various environmental conditions, ensuring that its fireproof and heat-insulating properties are maintained even after long-term use, including contact with certain chemicals or exposure to complex chemical environments. Finally, aluminum silicate has a relatively low density and is lightweight, so when used as a filler, it does not add excessive weight to the filled object or structure, facilitating handling, installation, and construction. In this embodiment, the thickness of the door curtain component is ≥45mm, and the wall thickness of the inner filling aluminum silicate material is ≥0.8mm.

[0040] To further improve the fire resistance and heat insulation performance of the roller shutter door, in this embodiment, one or more layers of aluminum foil are provided in the fire-resistant and heat-insulating filler. The aluminum foil layer can be aluminum foil film or aluminum foil cloth. Aluminum foil itself has excellent barrier properties and can effectively block heat radiation, thereby further improving the fire resistance and heat insulation performance of the roller shutter door.

[0041] As described above, the middle of the second curtain piece 32 is recessed to the side away from the first curtain piece 31 to form a first groove 321. The two sides of the first curtain piece 31 near the second curtain piece 32 are bent towards the second curtain piece 32 to form first bent portions 311. When the first curtain piece 31 and the second curtain piece 32 are connected, the bent portions are engaged with the sidewalls of the first groove 321, thereby ensuring that there is no relative movement after the first curtain piece 31 and the second curtain piece 32 are connected and fixed, resulting in higher connection strength. In this embodiment, the connection method of the first curtain piece 31 and the second curtain piece 32 is a fastening screw connection or a riveting connection; any method that meets the actual needs is acceptable and is not specifically limited here.

[0042] Furthermore, the first curtain component 31 has a first protrusion 312 extending outward on one side and a second protrusion 313 extending outward on the other side. When two adjacent curtain components are connected, the bottom of one of the first protrusions 312 can connect with the top of the other second protrusion 313, thereby limiting the rotation angle of the two adjacent curtain components and enabling them to form a single curtain when lowered and unfolded. In this embodiment, the second curtain component 32 has a first C-shaped opening 322 formed by bending one end of the first protrusion 312 toward the direction of the first protrusion 312, and a second C-shaped opening 323 formed by bending one end of the second curtain component 32 away from the second protrusion 313. The first C-shaped openings 322 and the second C-shaped openings 323 of two adjacent curtain components are rotatably connected, so that the two adjacent curtain components have a certain range of rotatable angles, making them more flexible to use.

[0043] It is worth noting that the side wall of the first curtain component 31 located below the first protrusion 312 is recessed inward to form a first mounting groove, in which a first barrier strip 5 is installed. When two adjacent curtain components are connected, the barrier strip can abut against the side of the second protrusion 313. The top of the second protrusion 313 is recessed inward to form a second mounting groove, in which a second barrier strip 6 is installed. The second barrier strip 6 can abut against the bottom of the first protrusion 312. In this embodiment, the first barrier strip 5 and the second barrier strip 6 are flame-retardant and smoke-proof adhesive strips, which effectively block the spread of smoke and dust when a fire occurs. Furthermore, smoke-proof expansion strips are affixed to the seams between two adjacent curtain components. These strips can expand under high temperatures during a fire, filling the gaps between the curtain components and further enhancing the blocking effect.

[0044] The curtain assembly 1 includes a frame 11 connected to the guide rail assembly 2, curtain panels 12 covering the frame 11, and a roller assembly 13 disposed within the frame 11. The top of the curtain assembly 3 is connected to the roller assembly 13, and the rotation of the roller assembly 13 can cause the curtain assembly 3 to rise or fall. The curtain panels 12 can be installed piece by piece on the frame 11, thereby facilitating maintenance operations within the curtain assembly 1.

[0045] In this embodiment, the roller component 13 includes a main shaft component 131 connected to the drive component and an auxiliary shaft component 132 disposed diagonally below the main shaft component 131. The curtain component 3 overlaps above the auxiliary shaft component 132. The auxiliary shaft component 132 can support the curtain component to a certain extent and guide the curtain component to the groove of the guide rail component 2, thereby effectively reducing the sinking and deflection changes of the curtain component due to gravity. At the same time, it can reduce the angle between the curtain component and the groove of the guide rail component 2, thereby greatly reducing the jamming accident between the curtain component and the guide rail component 2.

[0046] The drive assembly includes a drive component 7 and a transmission component. The transmission component connects the main shaft component 131 and the drive end of the drive component 7, so that the rotation of the drive end can drive the main shaft component 131 to rotate together. In this embodiment, the drive component 7 is a motor and the transmission component is a gear belt assembly. The drive component 7 is installed in the bag assembly 1 to form a complete bag drive module, which is convenient for installation and transportation.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
