Description

Technical Field

[0001] This utility model belongs to the field of honeycomb panels, specifically relating to a fireproof and soundproof honeycomb panel for curtain walls. Background Technology

[0002] Honeycomb panels are a lightweight, high-strength sandwich structure material. Their core layer consists of hexagonal units arranged in a honeycomb pattern, with panels covering both sides. They are formed by bonding or hot pressing. Honeycomb panels achieve a balance between lightweight and high strength through a biomimetic honeycomb structure. Their performance depends on the density of the core material and the material of the panels.

[0003] Ordinary honeycomb panels often use non-flame-retardant materials such as paper honeycomb for their core material, making them easily combustible in a fire and unable to effectively prevent the spread of fire. As the exterior facade of a building, the curtain wall is directly exposed to the external environment, and the fire resistance of the curtain wall material is crucial in the event of a fire. While metal honeycomb panels have some fire resistance, the high thermal conductivity of metal makes it difficult to block the heat generated by flames. The structural design of ordinary honeycomb panels mainly focuses on mechanical properties and lightweighting, resulting in weak sound insulation and absorption capabilities. In urban environments, traffic noise, industrial noise, and other external noise are severe, and ordinary honeycomb panels cannot effectively isolate these noises, leading to noise pollution in the indoor environment and affecting people's quality of life and work efficiency. Utility Model Content

[0004] To overcome the problems of poor fire resistance and difficulty in absorbing and blocking external noise when using honeycomb panels, a fireproof and soundproof honeycomb panel for curtain walls is proposed.

[0005] The technical solution of this utility model is as follows: a fireproof and soundproof honeycomb panel for curtain walls, comprising a fixed frame and a honeycomb core. The inner wall of the fixed frame is sequentially installed with a top plate, a first partition, a second partition, and a honeycomb core from top to bottom. The top plate has several through holes arranged in an equidistant array at its upper and lower ends. The first partition has several first slots arranged in an equidistant array at its upper and lower ends. The through holes are connected to the first slots. The inner wall of each first slot has a second slot. The second partition has several grooves arranged in an equidistant array at its upper and lower ends. Each groove contains a cotton block. The upper and lower ends of the second partition are fixedly connected to a mesh plate. The upper and lower ends of the cotton blocks are close to the mesh plate. The upper end of the honeycomb core is fixedly connected to a first support plate, and the lower end of the honeycomb core is fixedly connected to a second support plate. The cotton blocks are made of rock wool, and the second partition is made of ceramic.

[0006] Furthermore, a first connecting layer is fixed to the upper inner wall edge of the fixed frame, and a top plate is fixed to the lower end of the first connecting layer.

[0007] Furthermore, a second connecting layer is fixedly connected to the lower edge of the top plate, and a first partition is fixedly connected to the lower end of the second connecting layer.

[0008] Furthermore, a third connecting layer is fixedly connected to the lower edge of the first partition, and a second partition is fixedly connected to the lower end of the third connecting layer.

[0009] Furthermore, a fourth connecting layer is fixedly connected to the lower edge of the second partition, and a first support plate is fixedly connected to the lower end of the fourth connecting layer.

[0010] Furthermore, a fifth connecting layer is fixed to the lower edge of the second support plate, and the lower end of the fifth connecting layer is fixed to the lower inner wall edge of the fixed frame.

[0011] Furthermore, the fixed frame, top plate, honeycomb core, first support plate and second support plate are all made of metal, and the first connecting layer, second connecting layer, third connecting layer, fourth connecting layer and fifth connecting layer are all made of epoxy resin.

[0012] The beneficial effects of this utility model are as follows: Sound waves can be guided into the first slot through the through-hole in the top plate. The sound waves continuously bounce and weaken within the first slot. Combined with the second slot, the sound waves entering the first slot can be further weakened. Furthermore, the cotton blocks and the second partition can isolate flames. The slot and mesh plate divide the cotton blocks into sections, reducing cotton block accumulation and improving their uniformity. The honeycomb core, along with the first and second support plates, can support the top plate, the first partition, and the second partition. Compared to existing honeycomb panels, the added partition structure achieves sound absorption and heat insulation effects, weakens the bounce of sound waves entering the through-hole, and reduces heat transfer through the cotton blocks, thus improving the sound absorption and fire resistance of the honeycomb panel, meeting the basic requirements of a curtain wall.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-6 This utility model provides an embodiment: a fireproof and soundproof honeycomb panel for curtain walls, including a fixed frame 1 and a honeycomb core 5. The inner wall of the fixed frame 1 is sequentially installed from top to bottom with a top plate 2, a first partition 3, a second partition 4 and the honeycomb core 5. The top plate 2 has several through holes 6 arranged in an equidistant array at its upper and lower ends. The first partition 3 has several first slots 9 arranged in an equidistant array at its upper and lower ends. The through holes 6 are connected to the first slots 9. The inner wall of each first slot 9 is provided with a second slot 10. The second partition 4 has several slots 12 arranged in an equidistant array at its upper and lower ends. Each slot 12 is provided with a cotton block 14. The second partition 4 has a mesh plate 13 fixedly connected to its upper and lower ends. The upper and lower ends of the cotton block 14 are close to the mesh plate 13. The upper end of the honeycomb core 5 is fixedly connected with a first support plate 16 and the lower end of the honeycomb core 5 is fixedly connected with a second support plate 17. The cotton block 14 is made of rock wool and the second partition 4 is made of ceramic.

[0022] Sound waves can be guided into the first slot 9 through the through hole 6 on the top plate 2. The sound waves are continuously reduced by the rebound in the first slot 9. The second slot 10 can further reduce the sound waves entering the first slot 9, thereby achieving the sound absorption and sound insulation effect. The cotton block 14 and the second partition 4 can isolate the flame. The cotton block 14 is divided into blocks by the groove body 12 and the mesh plate 13, which can reduce the accumulation of the cotton block 14 and improve the uniformity of the cotton block 14. The honeycomb core 5, together with the first support plate 16 and the second support plate 17, can support the top plate 2, the first partition 3 and the second partition 4, and improve the strength. The fixing frame 1 can further improve the overall strength, thereby achieving sound insulation, fire prevention and support.

[0023] Please see Figures 3-4In this embodiment, a first connecting layer 7 is fixedly connected to the upper inner wall edge of the fixed frame 1, and a top plate 2 is fixedly connected to the lower end of the first connecting layer 7. In use, the top plate 2 and the fixed frame 1 can be connected through the first connecting layer 7, which improves the stability of the top plate 2 in use. A second connecting layer 8 is fixedly connected to the lower edge of the top plate 2, and a first partition 3 is fixedly connected to the lower end of the second connecting layer 8. In use, the top plate 2 and the first partition 3 can be connected through the second connecting layer 8, which improves the stability of the first partition 3 in use.

[0024] Please see Figures 4-5 In this embodiment, a third connecting layer 11 is fixedly connected to the lower edge of the first partition 3, and a second partition 4 is fixedly connected to the lower end of the third connecting layer 11. In use, the first partition 3 and the second partition 4 can be connected through the third connecting layer 11, thereby improving the stability of the second partition 4 in use. A fourth connecting layer 15 is fixedly connected to the lower edge of the second partition 4, and a first support plate 16 is fixedly connected to the lower end of the fourth connecting layer 15. In use, the first support plate 16 and the second partition 4 can be connected through the fourth connecting layer 15, thereby improving the stability of the first support plate 16 in use.

[0025] Please see Figures 3-6 In this embodiment, a fifth connecting layer 18 is fixedly connected to the lower edge of the second support plate 17. The lower end of the fifth connecting layer 18 is fixed to the lower inner wall edge of the fixed frame 1. In use, the second support plate 17 and the fixed frame 1 can be connected through the fifth connecting layer 18, which can improve the overall stability of the honeycomb panel. The fixed frame 1, top plate 2, honeycomb core 5, first support plate 16 and second support plate 17 are all made of metal. The first connecting layer 7, second connecting layer 8, third connecting layer 11, fourth connecting layer 15 and fifth connecting layer 18 are all made of epoxy resin. In use, the fire resistance can be effectively improved by connecting the metal plates and the honeycomb core 5. The epoxy resin connecting layer has good stability and heat resistance.

[0026] During operation, sound waves enter the first slot 9 through the through hole 6 and repeatedly bounce and weaken within the first slot 9 and the second slot 10, enabling the first partition 3 to achieve sound absorption and insulation. When flames are generated, the metal top plate 2, the fixing frame 1, the honeycomb core 5, the first support plate 16, and the second support plate 17 can isolate the flames. When the heat generated by the flames is conducted to the second partition 4, the cotton block 14 can block the heat conduction to a certain extent, thereby reducing the heat transfer and giving the honeycomb panel heat insulation properties. When vibration occurs, the honeycomb core 5 can absorb the vibration and reduce the impact of the vibration on the honeycomb panel.

[0027] Through the above steps, the through hole 6 on the top plate 2 can guide sound waves into the first slot 9. The sound waves continuously bounce and weaken in the first slot 9. In conjunction with the second slot 10, the sound waves entering the first slot 9 can be further weakened, thereby achieving the sound absorption and sound insulation effect. The cotton block 14 and the second partition 4 can isolate the flame. The cotton block 14 is divided and isolated by the groove 12 and the mesh plate 13, which can reduce the accumulation of cotton block 14 and improve the uniformity of cotton block 14. This solves the problem that the honeycomb panel has poor fire resistance and is difficult to absorb and block external noise when in use.
