Description

Technical Field

[0001] This invention belongs to the field of building materials, specifically a sound-absorbing color steel sandwich panel. Background Technology

[0002] The use of color steel sandwich panels is becoming increasingly widespread, especially in industrial buildings such as drying rooms, spray booths, and factories. Industrial plants generate significant noise pollution during operation, which can affect people working and living in the surrounding area. In addition, many simple houses also use color steel sandwich panels, and rainwater can generate considerable noise, affecting the people living inside. Therefore, the sound absorption capacity of color steel sandwich panels is a very important requirement.

[0003] For example, the honeycomb structure described in patent 200410024948.7 is used for sound absorption. The honeycomb structure continuously reflects sound waves to reduce the energy of the sound waves, thereby completing the sound absorption work. However, in actual use, the arrangement and size of the holes have a great influence on the actual sound absorption results. If the holes are too large, the sound absorption effect will be greatly reduced. If the holes are too small, too many sound waves will be reflected, thus failing to achieve the sound absorption effect. If the holes are too dense, the structural strength will be reduced. Over-reliance on size makes the processing and production very difficult, and the effect fluctuates greatly. Therefore, there is a need for a color steel sandwich panel that can overcome the above problems. Summary of the Invention

[0004] This invention provides a sound-absorbing color steel sandwich panel with good sound absorption and noise reduction effect, which is especially suitable for the construction of factories and temporary residences. The technical problem to be solved is that the demand for sound absorption of color steel sandwich panels is increasing, but the sound absorption effect of current sound-absorbing materials is not ideal and relies too much on dimensional accuracy.

[0005] The technical solution adopted in this invention is:

[0006] A sound-absorbing color steel sandwich panel includes a sound-absorbing layer and a sandwich layer. The sound-absorbing layer includes a support plate, an outer sound-absorbing plate, an inner sound-absorbing plate, an outer filling layer, and an inner filling layer. The support plate is provided with a structural reinforcement support structure. The outer sound-absorbing plate is provided with outer sound-absorbing holes. An outer filling layer is provided between the outer sound-absorbing plate and the support plate. The outer filling layer is fixedly connected to the outer sound-absorbing plate and the support plate. The inner sound-absorbing plate is provided with inner sound-absorbing holes. The sandwich layer and the inner filling layer are fixedly connected to both sides of the inner sound-absorbing plate, respectively. The inner filling layer is fixedly connected to the outer sound-absorbing plate.

[0007] Furthermore, the support plate is provided with serrated grooves.

[0008] Furthermore, the outer sound-absorbing plate is configured with a structure having serrated grooves, and the outer sound-absorbing holes are evenly distributed on the raised structure of the serrated grooves.

[0009] Furthermore, the recessed part of the groove on the support plate is opposite to the protrusion of the outer sound-absorbing plate.

[0010] Furthermore, the inner and outer silencing holes are positioned alternately.

[0011] Furthermore, the outer filling layer is provided with a filler, and a support plate and an outer sound-absorbing plate are respectively bonded to opposite sides of the outer filling layer. Serrated grooves are provided on both sides of the outer filling layer.

[0012] Furthermore, the inner sound-absorbing plate is provided with serrated grooves.

[0013] Furthermore, the inner filling layer is provided with a filler, and the surface of the inner filling layer is shaped according to the shape of the plate to which it is bonded.

[0014] Furthermore, the inner sound-absorbing plate is a flat plate, and the two ends of the inner sound-absorbing plate, the outer sound-absorbing plate, and the support plate are fixedly connected.

[0015] The above structure has the following beneficial effects:

[0016] 1. By using a double-layer sound-absorbing panel and a double-layer sound-absorbing layer, the problem of poor sound absorption quality and unstable sound absorption quality of existing sound-absorbing color steel sandwich panels is overcome, thus ensuring the sound absorption effect of the color steel sandwich panels.

[0017] 2. Due to the adoption of a serrated structure, the existing sound-absorbing color steel sandwich panels have overcome the problems of reduced structural support strength and poor sound absorption effect caused by the sound absorption structure. This ensures the support effect of the color steel sandwich panels and improves the sound absorption effect of the panel structure, thus promoting faster sound wave energy dissipation.

[0018] 3. By using an alternating combination of outer and inner sound-absorbing plates, inner and outer filling layers, the problem of existing sound-absorbing plates relying too much on the dimensional accuracy of the sound-absorbing structure is overcome. This ensures the sound-absorbing effect while reducing the precision of the processing, thus better guaranteeing the efficiency and stability of the sound-absorbing effect.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1-8 As shown:

[0031] A sound-absorbing color steel sandwich panel includes a sound-absorbing layer 1 and a sandwich layer 2. The sound-absorbing layer 1 includes a support plate 11, an outer sound-absorbing plate 12, an inner sound-absorbing plate 13, an outer filling layer 14, and an inner filling layer 15. The support plate 11 has a serrated support structure for structural reinforcement. The top and bottom of the serrated structure are trapezoidal. The outer sound-absorbing plate 12 has a self-supporting structure. The protrusions of the serrated structure of the outer sound-absorbing plate 12 correspond to the recesses of the serrated support structure of the support plate 11. The outer sound-absorbing plate 12 has external sound-absorbing holes 3. The outer sound-absorbing plate 12 and the support plate 11 work together to increase the number of sound wave reflections, thereby reducing sound wave energy. Sound holes 3 are used for sound waves to pass through and be reflected a second time, so as to better reduce the sound wave energy and greatly improve the sound absorption effect. An outer filling layer 14 is provided between the outer sound absorption plate 12 and the support plate 11. The outer filling layer 14 can absorb more sound and is bonded to the outer sound absorption plate 12 and the support plate 11. The inner sound absorption plate 13 is provided with inner sound absorption holes 4. The inner sound absorption holes 4 and the outer sound absorption holes 3 are staggered. The sound waves are reflected a second time through the staggered outer sound absorption holes 3 and inner sound absorption holes 4, which greatly reduces the sound wave energy and thus effectively reduces the volume of the sound. The core layer 2 and the inner filling layer 15 are bonded to both sides of the inner sound absorption plate 13, and the inner filling layer 15 is bonded to the outer sound absorption plate 12. The outer sound absorption holes 3 are evenly arranged at the protruding structures of the sawtooth groove.

[0032] The recessed part of the groove on the support plate 11 and the protrusion of the outer silencing plate 12 can better reflect sound waves with the help of the trapezoidal sawtooth structure. As the number of reflections increases, the sound wave energy is effectively reduced. The trapezoidal structure makes the probability of sound waves passing through the outer silencing hole 3 and the inner silencing hole 4 decrease, thereby increasing the number of reflections.

[0033] The outer filling layer 14 contains a filler material, and the support plate 11 and the outer sound-absorbing plate 12 are respectively bonded to opposite sides of the outer filling layer 14. Serrated grooves are provided on both sides of the outer filling layer 14. The filler material can be asbestos or glass wool, and its serrated structure allows for better adhesion to the support plate 11 and the outer sound-absorbing plate 12, significantly enhancing the structural strength of the color steel sandwich panel. Compared to traditional non-grid filler layers, this method effectively increases the structural strength of the color steel sandwich panel.

[0034] The inner sound-absorbing plate 13 is provided with serrated grooves. By providing serrated grooves on the inner sound-absorbing plate 13, together with the support plate 11 and the outer sound-absorbing plate 12, the structural strength can be better increased, greatly increasing the structural strength of the inner sound-absorbing plate 13, so that the color steel sandwich panel can independently support the wall even without the provision of transverse reinforcement structures.

[0035] The inner silencing plate 13 is a flat plate, and the inner silencing plate 13, the outer silencing plate 12, and the support plate 11 are welded together at both ends. By connecting the inner silencing plate 13, the outer silencing plate 12, and the support plate 11 into a whole, the structural strength is increased, and the overall structure is made more stable.

[0036] The inner filling layer 15 is filled with asbestos or glass wool, and the surface of the inner filling layer 15 is shaped according to the shape of the board it is bonded to. The shape of the inner filling layer 15 can increase the structural strength.

[0037] How this example works:

[0038] In practical applications, because the support plate 11, outer silencing plate 12, and inner silencing plate 13 are integrated into a single unit, the overall structure is more stable. Furthermore, since the outer filling layer 14 and inner filling layer 15 have the same structure as the two sides, the bonding is more stable. This more stable bonding results in stronger structural strength. The grid structure of the support plate effectively reflects sound waves, thus affecting sound wave propagation. The serrated structure of the outer silencing plate 12 can better cooperate with the support plate 11 to perform secondary reflection of sound waves. The trapezoidal serrated structure also effectively increases the number of sound wave reflections. The cooperation between the inner silencing hole 4 and the outer silencing hole 3 allows the sound waves to undergo a third reflection between the outer silencing plate 12 and the inner silencing plate 13, significantly reducing sound wave energy and thus effectively silencing the sound.

[0039] Because sound-absorbing layers 1 are set on both sides of the sandwich layer 2, it not only effectively blocks external noise, but also effectively blocks internal noise, so that the inside and outside do not affect each other. The structure using this color steel sandwich panel can obtain a quieter environment and effectively avoid noise pollution.

[0040] This color steel sandwich panel effectively reduces sound wave energy, effectively eliminates and isolates noise, and can prevent noise from factories and other noisy environments from affecting surrounding residents, while also preventing noise from affecting each other between residents.
