[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0026] Please refer to Figures 1 to 7 The double-face metal composite board provided by the utility model, as shown by the figure, comprises cladding plates 1 and inner base plates 2, the cladding plates 1 are arranged in two groups in an up-down manner, the inner base plates 2 are between the two groups of cladding plates 1, the upper and lower side surfaces of the inner base plates 2 are provided with hanging teeth 3, and the outer surfaces of the hanging teeth 3 are all attached with soundproof cotton 4.
[0027] The hanging tooth 3 comprises a connecting block 31, an extension block 32 and a buckling block 33, the bottom end of the connecting block 31 is fixedly connected with the outer walls of the cladding plate 1 and the inner base plate 2 respectively, the surface sides of the connecting block 31 are both fixedly connected with the extension block 32, and the end sides of the extension block 32 are both fixedly connected with the buckling block 33.
[0028] The hanging tooth 3 is arranged in multiple groups, the gap between the two adjacent groups of hanging teeth 3 is slightly larger than the width of one group of hanging teeth 3, and each group of hanging teeth 3 is arranged in an alternating array of one positive and one negative.
[0029] The bottom end of the buckling block 33 is provided with a chamfer, and the curved end of the buckling block 33 is attached with the inner arc surface of the other extension block 32.
[0030] Please refer to Figure 3 And Figure 4 As shown in the figure, the hanging teeth 3 fixedly arranged at the upper ends of the cladding plate 1 and the inner base plate 2 have two array modes, Figure 4 As shown in the figure, every six groups of hanging teeth 3 arranged in a vertical linear array and the other groups of hanging teeth 3 arranged in a horizontal linear array are arranged in an alternating array, and the multiple groups of hanging teeth 3 are arranged in different directions, so that the buckling structure of the plate material after buckling can be kept stable, the occurrence of the misalignment of the plate material due to the buckling of the cladding plate 1 and the inner base plate 2 in one direction and the influence of external movement and the like can be avoided, the structural stability can be affected, and the Figure 3 The array mode has a relatively low cutting difficulty and can keep the plate material structure stable, Figure 3 As shown in the figure, every six groups of hanging teeth 3 arranged in a vertical linear array and the other six groups of hanging teeth 3 arranged in a horizontal linear array are arranged in an alternating array, and the Figure 4 The array mode has a relatively low cutting difficulty and can keep the plate material structure stable,
[0031] Figure 3 And Figure 4 The two hanging tooth array modes shown in the figures have their own unique advantages, Figure 4The array mode of the first aspect is better in cutting difficulty and construction convenience, and is suitable for scenes with high requirements for processing efficiency. Figure 3 The array mode of the second aspect is more prominent in structural stability and deformation resistance, and is suitable for applications with high requirements for structural strength and durability. The two array modes can be selected according to specific use requirements and scenes to achieve the best structural performance and construction efficiency.
[0032] The two groups of extension blocks 32 are arranged in semicircular arc shapes, and the outer arc surfaces of the two groups of extension blocks 32 are arranged in close contact. The inner arc surface angle of each group of extension blocks 32 is between 20° and 35°, and the outer arc surface angle of two adjacent extension blocks 32 is between 45° and 60°.
[0033] When external pressure is applied to the cladding plate 1, the extension block 32 can easily extend outward due to its pre-set circular arc state. By utilizing the initial state of the extension block 32 slightly extending outward, the extension block 32 can smoothly expand outward during the pressure process, which not only helps to achieve tight clamping connection between the two groups of buckling blocks 33, but also ensures the stability and reliability of the entire structure under stress.
[0034] When the angle of the inner arc surface is set between 20° and 35°, and the angle of the outer arc surface is set between 45° and 60°, the gap between the teeth 3 can be maximized while ensuring the clamping connection between the two groups of buckling blocks 33 is not affected. This not only ensures the stability of the connection, but also provides convenience for the placement and installation of the two groups of plates. The larger gap makes it easier to align and position the plates during installation, reducing errors and adjustment time during installation, improving overall construction efficiency, and enhancing the convenience of construction, making the entire installation process smoother and more efficient.
[0035] In different application scenarios, the angles of the inner arc surface and the outer arc surface can be adjusted according to the actual stress situation and installation requirements. In scenarios requiring stronger sound insulation effect, the gap between the teeth 3 can be further optimized by adjusting the angles to increase the filling space of the sound insulation cotton 4 and improve the sound insulation performance. In scenarios requiring higher structural strength, the connection strength between the buckling blocks 33 can be enhanced by adjusting the angles to ensure the stability of the structure during long-term use.
[0036] The outer surface of the sound insulation cotton 4 is the same shape as the surface of the teeth 3, and slightly larger than the size of the teeth 3.
[0037] The sound insulation cotton 4 is wrapped on the surface of the hanging tooth 3, and after the clamping of the hanging tooth 3 between the clamping plate 1 and the inner base plate 2, the sound insulation effect is obvious. When the two groups of plates are clamped by the hanging tooth 3, the sound insulation cotton 4 is in contact with the sound insulation cotton 4 and is connected. This connection effectively reduces the direct sound transmission between the metal parts, because the metal material generally has good sound conduction, and the sound insulation cotton can weaken the conduction.
[0038] When the sound propagates between the plates, it first contacts the sound insulation cotton 4 on the surface of the hanging tooth 3. The internal structure of the sound insulation cotton 4 is composed of a large number of fibers that can capture and absorb the energy of the sound wave. When the sound wave enters the sound insulation cotton 4, it is constantly reflected and scattered between the fibers, which consumes the energy of the sound wave and reduces the intensity of the sound wave. As the propagation path of the sound wave in the sound insulation cotton 4 increases, its energy is gradually absorbed, resulting in a significant decrease in the penetration ability of the sound wave.
[0039] The surface of the sound insulation cotton 4 can also reflect part of the sound wave, further reducing the penetration of the sound wave. The double effect of reflection and absorption effectively controls the transmission of sound between the plates. Even after the hanging tooth 3 is clamped, the connection between the sound insulation cotton 4 can maintain a certain gap, which can be used as additional sound wave reflection and absorption space to further enhance the sound insulation effect.
[0040] Working principle: The hanging tooth 3 is arranged between the clamping plate 1 and the inner base plate 2. Before compression, the hanging tooth 3 is alternately placed between the hanging tooth 3, so that the hanging tooth 3 is all in the same horizontal plane, in state one. Then the surface of the two groups of clamping plates 1 is subjected to pressure by the compression equipment, so that the clamping plate 1 and the hanging tooth 3 inside the inner base plate 2 are deformed. The extension block 32 on both sides of the connecting block 31 extends to both sides with the connecting block 31 as the center, so that the two groups of clamping blocks 33 are clamped with each other, in state two. The position of the inner base plate 2 and the clamping plate 1 is limited and fixed, and after clamping, each group of hanging tooth 3 is still in a certain space between the clamping plate 1 and the inner base plate 2. The space structure can change the propagation path of the sound wave, increase the reflection and refraction of the sound wave, and reduce the transmission ability of the sound, so that the double-sided metal composite plate has a multi-layer sound insulation structure and has a strong sound insulation effect.
[0041] Finally, it should be pointed out that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent substitution, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
