Description

Technical Field

[0001] This utility model relates to the field of sound insulation board technology, and in particular to a building sound insulation board. Background Technology

[0002] Building sound insulation panels are building materials used to reduce noise transmission, and are usually made of multiple layers of composite materials.

[0003] Typical building sound insulation panels use a keel frame as a support, then fill the spaces between the keels with sound-absorbing material to absorb sound waves from the cavities, and finally glue plasterboard onto the sound-absorbing material. Installing the keel frame is not only cumbersome and time-consuming, but the sound-absorbing material only fills the cavities and cannot block the structural sound transmitted by the keel, resulting in poor overall sound insulation.

[0004] Therefore, this application provides a building sound insulation panel to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this utility model is to provide a building sound insulation board that solves the problems of cumbersome construction and poor sound insulation effect of existing sound insulation boards.

[0006] To solve the above-mentioned technical problems, this utility model provides a building sound insulation board, including a multi-layer composite sound insulation board. The multi-layer composite sound insulation board is arranged from the inside to the outside as follows: a first aluminum alloy plate, sound-absorbing foam, a second aluminum alloy plate, and a gypsum board are attached to each other. Sound-absorbing foam is embedded in the edge A around the outer perimeter of the first aluminum alloy plate. The sound-absorbing foam is nested in the edge B of the second aluminum alloy plate. Angle strip B and an angle strip A are integrally provided on the top surface of the edge B and the edge A, respectively. A number of sliders are embedded in any two pairs of opposite angle strips B and angle strip A. The sliders fix the sound-absorbing foam by locking the first aluminum alloy plate and the second aluminum alloy plate.

[0007] A further improvement of the present invention is that the first aluminum alloy plate also includes a first base plate on the bottom surface, and a side guard A is integrally provided on the four edges of the outer side surface of the first base plate. An L-shaped corner strip A is integrally provided on the top surface of the side guard A, and the length of the corner strip A is equal to the side length of the parallel sound-absorbing foam.

[0008] A further improvement of the present invention is that: wavy first limiting strips are symmetrically arranged on opposite sides of the outer side of the first base plate within the side block A, and the first limiting strips are adapted to be embedded in and abut against the wavy surface of the sound-absorbing foam.

[0009] A further improvement of the present invention is that: a second limiting strip with a triangular cross-section is vertically provided at both ends of the first limiting strip, and the second limiting strip is embedded parallel to the triangular groove of the wave surface.

[0010] A further improvement of the present invention is that: a number of tapered holes with larger inner diameters and smaller outer diameters are opened on the first base plate body, the maximum diameter of the tapered holes being 0.5~2.4mm and the taper being 10~40°.

[0011] A further improvement of the present invention is that the second aluminum alloy plate also includes a second base plate on the bottom surface, and a side rail B is integrally provided on the outer side of the second base plate around its perimeter. An L-shaped corner strip B is integrally provided on the top surface of the side rail B, and the length of the corner strip B is equal to the length of the corresponding corner strip A.

[0012] A further improvement of this utility model is that: a number of micro-circular holes are provided on the second base plate body, with a diameter of 1~2mm.

[0013] A further improvement of this utility model is that the slider is a cuboid-like structure, and L-shaped grooves are symmetrically opened on two opposite sides of the slider body, with opposite corner strips A and B respectively fitted into the grooves.

[0014] A further improvement of this utility model is that the sound-absorbing foam is melamine foam, and the inner surface of the sound-absorbing foam is a corrugated surface.

[0015] A further improvement of this utility model is that the inner side of the first aluminum alloy plate abuts against the building wall.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. The present invention provides a building sound insulation board. The multi-layer composite sound insulation board has a four-layer structure of “micro-conical hole aluminum alloy plate + sound-absorbing material + micro-round hole aluminum alloy plate + gypsum board”, which optimizes sound absorption and sound insulation at the same time, forming a “sound absorption-noise reduction-sound absorption-sound insulation” composite structure. It attenuates sound energy through multiple reflections and absorptions, and is especially effective in suppressing mid-to-high frequency noise. It can also improve low-frequency absorption through the conical hole design.

[0018] 2. The present invention provides a building sound insulation board in which a sound-absorbing material (melamine foam) is abutted and filled between the first aluminum alloy plate and the second aluminum alloy plate of the multi-layer composite sound insulation board. The sound-absorbing material is initially fixed by the first limiting strip and the second limiting strip on the bottom surface of the first aluminum alloy plate being adapted to embed the corrugated surface of the abutting sound-absorbing material. The corner strips B and A at the edges of the first aluminum alloy plate and the second aluminum alloy plate are locked and fixed by the slider, and the sound-absorbing material is fixed and clamped again.

[0019] 3. The present invention provides a building sound insulation board, wherein a number of conical holes with larger inner diameters and smaller outer diameters are opened on the first base plate body. The conical hole design guides sound waves into the sound absorption layer through the gradually changing aperture, reducing sound wave reflection (similar to the Helmholtz resonator principle) and enhancing sound absorption efficiency.

[0020] 4. The building sound insulation board provided by this utility model is lightweight, easy to install, corrosion-resistant, moisture-proof, and has a long service life. Attached Figure Description

[0036] The present invention will be further explained below with reference to specific embodiments.

[0037] like Figures 1-10As shown, this embodiment provides a building sound insulation panel, including a multi-layer composite sound insulation panel 1. The multi-layer composite sound insulation panel 1 is sequentially abutted from the inside out by a first aluminum alloy plate 2, sound-absorbing foam 3, a second aluminum alloy plate 4, and a gypsum board 5. Sound-absorbing foam 3 is embedded within the edge bands A22 around the outer perimeter of the first aluminum alloy plate 2. The sound-absorbing foam 3 is nested within the edge bands B42 of the second aluminum alloy plate 4. Corner strips B43 and A23 are integrally formed on the top surfaces of edge bands B42 and A22, respectively. Several sliders 6 are embedded on any two pairs of opposing corner strips B43 and A23. The sliders 6 fix the sound-absorbing foam 3 by locking the first aluminum alloy plate 2 and the second aluminum alloy plate 4. Specifically, the multi-layer composite sound insulation panel 1 can be customized to different sizes and... With varying thicknesses, the inner surface of the first aluminum alloy plate 2 is a flat structure, abutting against the building wall. The outer surface of the first aluminum alloy plate 2 abuts against nested sound-absorbing foam 3, and the outer surface of the sound-absorbing foam 3 abuts against the inner surface of the second aluminum alloy plate 4. The outer surface of the second aluminum alloy plate 4 is flat, and gypsum board 5 is glued to the outer surface of the second aluminum alloy plate 4. This four-layer composite structure forms a multi-level sound insulation layer of "sound absorption-sound attenuation-sound absorption-sound insulation". Through multiple reflections and absorptions, it attenuates sound energy, especially effectively suppressing mid-to-high frequency noise. It can also improve low-frequency absorption through the design of the conical hole 211. At the same time, any two opposite edges of the first aluminum alloy plate 2 and the second aluminum alloy plate 4 can be locked and fixed by the matching embedded slider 6, reducing the amount of glue used, making it economical and environmentally friendly. In addition, the overall weight is light and easy to install.

[0038] like Figures 2-5As shown, in this embodiment, the inner side of the first aluminum alloy plate 2 abuts against the building wall; the first aluminum alloy plate 2 also includes a first base plate 21 on the bottom surface, and a side guard A22 is integrally provided on the four edges of the outer side of the first base plate 21. An L-shaped corner strip A23 is integrally provided on the top surface of the side guard A22, and the length of the corner strip A23 is equal to the side length of the parallel sound-absorbing foam 3; wavy first limiting strips 212 are symmetrically provided on opposite sides of the outer side of the first base plate 21 within the side guard A22, and the first limiting strips 212 are adapted to be embedded in the wavy surface 31 that abuts against the sound-absorbing foam 3; second limiting strips 213 with triangular cross sections are respectively provided perpendicularly at both ends of the first limiting strips 212, and the second limiting strips 213 are embedded parallel to the triangular cross sections of the wavy surface 31. Within the groove 311; specifically, the first layer of the multi-layer composite sound insulation board 1 is a first aluminum alloy plate 2 that abuts against the building wall. The first aluminum alloy plate 2 is similar to a rectangular tray structure. The inner cavity of the first aluminum alloy plate 2 is adapted to embed sound-absorbing foam 3. The height of the side guards A22 around the outer perimeter of the first aluminum alloy plate 2 is 1 / 5 of the thickness of the sound-absorbing foam 3. One end of the L-shaped corner strip A23 is vertically and integrally set on the top surface of the side guard A22, and the other end of the corner strip A23 faces the sound-absorbing foam 3. The corner strip A23 is used to embed the slider 6 to fix the edges of the first aluminum alloy plate 2 and the second aluminum alloy plate 4. The first limiting strip 212 and the second limiting strip 213 are adapted to abut against the corrugated surface 31 to further fix the sound-absorbing foam 3 and prevent the sound-absorbing foam 3 from moving or misaligning.

[0039] like Figure 4-5 As shown, in this embodiment, the first base plate 21 has several conical holes 211 with larger inner diameters and smaller outer diameters. The maximum diameter of the conical holes 211 is 0.5~2.4mm, and the taper is 10~40°. The sound-absorbing foam 3 is melamine foam, and the inner surface of the sound-absorbing foam 3 is a corrugated surface 31. Specifically, the maximum diameter of the conical holes 211 is 1.2mm, and the taper is 20°. The diameter of the conical holes 211 is larger inside and smaller outside, that is, the diameter is larger on the side that is in contact with the building wall and smaller on the side that is in contact with the sound-absorbing foam 3. The gradually changing diameter guides the sound waves into the sound-absorbing foam 3. The corrugated surface 31 expands the plane into a three-dimensional space through the undulating structure, which significantly increases the contact area with the sound waves, reduces sound wave reflection, and enhances the sound absorption efficiency.

[0040] like Figures 7-9As shown, in this embodiment, the second aluminum alloy plate 4 also includes a second base plate 41 on the bottom surface. A side rail B42 is integrally provided on the outer perimeter of the second base plate 41, and an L-shaped corner strip B43 is integrally provided on the top surface of the side rail B42. The length of the corner strip B43 is equal to the length of the corresponding corner strip A23. A plurality of micro-circular holes 411 are provided on the body of the second base plate 41, and the diameter of the circular holes 411 is 1~2mm. Specifically, the second aluminum alloy plate 4 is the same size as the first aluminum alloy plate 2. The inner and outer sides of the second base plate 41 are both flat, respectively abutting the outer side of the sound-absorbing foam 3 and the inner side of the gypsum board 5. The side rail B42 is mirror-symmetrical to the side rail A22 with the plane where the sound-absorbing foam 3 is located as the mirror plane. The corner strip B43 is similarly mirror-symmetrical to the corner strip A23. The corresponding corner strips B43 and A23 on the same side of the sound-absorbing foam 3 are fitted with sliders 6.

[0041] This utility model provides a working principle for a building sound insulation board: In use, the sound-absorbing foam 3 is embedded between the first aluminum alloy plate 2 and the second aluminum alloy plate 4, wherein the wavy surface 31 of the sound-absorbing foam 3 is embedded in the first limiting strip 212 and the second limiting strip 213, and the inner side of the second aluminum alloy plate 4 abuts against the outer plane of the sound-absorbing foam 3. Then, 2 to 4 sliders 6 are embedded and fitted onto the body of the corner strip B43 and the corner strip A23 from both ends, so that the sound-absorbing foam 3, the first aluminum alloy plate 2 and the second aluminum alloy plate 4 are combined into one. Finally, the plasterboard 5 is glued to the outer side of the second aluminum alloy plate 4.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
