Please note that, in order to clearly demonstrate the structure of the components in the embodiments of the invention, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.

[0030] A schematic diagram of a sound-absorbing structure 100 for building engineering is provided in one embodiment of the present invention, as shown below. Figure 1 As shown. The sound-absorbing structure 100 used in building engineering includes a sound-absorbing body 10, which is a thin-walled shell with a corrugated structure on its side. When sound waves encounter the corrugated structure, they are reflected and partially absorbed, thereby improving the sound absorption and reverberation effect.

[0031] Furthermore, the corrugated structure includes at least one protrusion 20, the longitudinal cross-section of which is triangular. Figure 1 In the middle, the number of protrusions 20 is 3. It is understood that the corrugated structure may also include other numbers of protrusions 20.

[0032] Figure 1 In the embodiment shown, the sound-absorbing body 10 is provided with sound-absorbing cotton 30 inside, and an adhesive layer 40 is disposed between the sound-absorbing cotton 30 and the inner sidewall of the sound-absorbing body 10; further, the adhesive layer 40 is made of high-strength latex and has a thickness of 1-3mm.

[0033] In some embodiments, the adhesive layer 40 can also be prepared by the following method. The adhesive layer 40 is prepared from the following ingredients by weight: polyacrylamide 20-30 parts, sodium silicate 15-20 parts, filler 5-6 parts, auxiliary 3-5 parts, surfactant 2-4 parts, acetone 20-30 parts, and water 35-40 parts. The adhesive layer 40 described above can effectively improve the adhesion of the sound-absorbing cotton 30 to the inner side wall of the sound-absorbing body 10, achieving good sound-absorbing and reverberation effects.

[0034] Figure 1 In some embodiments, the other side of the sound-absorbing body 10 is provided with a sealing plate 50, which is arranged on the opposite side of the corrugated structure. The upper side of the sealing plate 50 is provided with a plurality of baffle plates 60 arranged in a staggered manner, which at least partially block the openings corresponding to the protrusions 20.

[0035] Further, the outer peripheral wall of the sound-absorbing body 10 is provided with a through sound-absorbing hole 10a, as shown in Figure 3 As one aspect of the present embodiment, the porosity of the sound-absorbing hole 10a is 30%-50% to adjust and control the sound-absorbing and reverberation effects of the sound-absorbing structure.

[0036] In the present application, the sound-absorbing cotton 30 is fixed to the inner side wall of the protrusion 20 by spraying high-temperature gas to the adhesive layer 40.

[0037] Figure 1 In the embodiment shown in the figure, the baffle plate 60 is a lightweight porous plate arranged above the sealing plate 50 by a support rod 61. Further, the distance between the baffle plate 60 and the sealing plate 50 is 20-150 mm.

[0038] In some embodiments, the vertical spacing between adjacent baffle plates 60 is 5-10 mm, and the overlapping length of adjacent baffle plates 60 in the transverse direction is 20-30 mm. The arrangement of the baffle plate 60 can further block the propagation of sound waves in the direction of the sealing plate 50.

[0039] Figure 1 In the embodiment shown in the figure, the upper side of the sealing plate 50 is provided with a first honeycomb plate 70 and a second honeycomb plate 80, as shown in Figure 2 The second honeycomb plate 80 is arranged above the first honeycomb plate 70.

[0040] Further, the pore size of the first honeycomb plate 70 is larger than that of the second honeycomb plate 80. The distribution density of the honeycomb structure on the second honeycomb plate 80 is greater than that on the first honeycomb plate 70, to further block the propagation of sound waves to the sealing plate 50.

[0041] As one aspect of this embodiment, the first honeycomb panel 70 and the second honeycomb panel 80 have the same thickness. Preferably, the thickness of the first honeycomb panel 70 and the second honeycomb panel 80 is 10-20 mm.

[0042] Figure 1 In the embodiment shown, the longitudinal cross-section of the protrusion 20 is an equilateral triangle, and the length of the sound-absorbing body 10 is equal to the width of the sound-absorbing body 10, such as... Figure 3 As shown.

[0043] Figure 4 This is a schematic diagram of a sound-absorbing structure provided in another embodiment of the present invention. In this embodiment, the sound-absorbing structure 110 is provided with a protrusion 20, the internal structure of which is similar to... Figure 1 The sound-absorbing structure 100 in the illustrated embodiment is similar and will not be described again here.

[0044] Figure 5 yes Figure 4 The diagram shows the corresponding sound-absorbing body 10, which is equipped with multiple sound-absorbing holes 10a. The porosity of the sound-absorbing holes 10a can be flexibly set according to the sound absorption and reverberation conditions.

[0045] Figure 6 This is a schematic diagram of an application embodiment of the sound-absorbing structure 100 described in this invention. In this embodiment, the sound-absorbing structures 100 are arranged horizontally and vertically in a staggered manner on the inner side wall of the building wall to transform or decorate the building into a recording studio, broadcasting studio, or sound testing laboratory, etc. That is, the length directions of the protrusions 20 arranged on adjacent sound-absorbing structures 100 are perpendicular to each other to ensure the effectiveness of the sound-absorbing structure.

[0046] Compared with the shortcomings and deficiencies of existing technologies, the present invention provides a sound-absorbing structure for building engineering. Its structure is reasonable, and the sound absorption effect is improved by combining sound-absorbing cotton and staggered baffles. In addition, the honeycomb panels above the sealing plate have different pore sizes to improve the sound mixing effect of the sound-absorbing structure.

[0047] This invention is not limited to the above-described embodiments. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
