[0046] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the accompanying drawings and specific embodiments are only exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0047] Embodiment 1: See also Figure 1 to Figure 8 The present embodiment provides a modular lightweight soundproof wall, the structure of which at least includes a soundproof bracket 1, a connector 3 and an outer covering layer 4. Further, the soundproof bracket 1 is formed with a plurality of soundproof chambers 100, and the soundproof chambers 100 are provided with resonant soundproof particles 103. The inner sides of the two groups of soundproof brackets 1 are arranged opposite to each other and form a soundproof air layer 10; the connector 3 is located in the soundproof air layer 10 and connects the two groups of soundproof brackets 1, and the outer covering layer 4 is formed on the outer side of the surface of the soundproof bracket 1.

[0048] See also Figure 4 , Figure 6 Combined with Figure 7 The present embodiment includes a structural grid 2, the number of which preferably corresponds to the number of the muffler brackets 1. In the present embodiment, two groups of structural grids 2 are respectively arranged on the outer sides of the two groups of muffler brackets 1. In the present embodiment, the material of the structural grid 2 is not limited, and is preferably a steel wire mesh; further preferably, a flat steel wire mesh or a corrugated steel wire mesh can be used.

[0049] See also Figure 5~Figure 8 The purpose of the silencer bracket 1 is to provide a silencer chamber 100 and can provide auxiliary structural support for the wall. Therefore, the silencer bracket 1 is not limited to a specific structure. For the structural adaptation of the wall, in a preferred embodiment of the present embodiment, the silencer bracket 1 is a grid plane bracket, and the honeycomb grid plane bracket has a plurality of grid holes, and the grid holes are provided with a top seal 102 and a bottom seal 101, and the silencer chamber 100 is formed between the top seal 102 and the bottom seal 101.

[0050] Furthermore, the mesh holes are not limited to the form. In this embodiment, hexagonal mesh holes are preferred, and quadrilateral mesh holes can also be used. The material can be a polymer material, such as FRP material, etc., and the silencer bracket 1 is integrally formed by injection molding. The top seal 102 and the bottom seal 101 are made of polymer insulation material. Furthermore, the bottom seal 101 is preferably made of the same material as the silencer bracket 1, and the top seal 102 is preferably made of a film material.

[0051] In order to facilitate the subsequent molding of the outer covering layer 4, the top seal 102 is preferably set at the half-height position 105 or 1 / 3 of the hole depth in the mesh hole, and an embedding groove 104 of half height or 2 / 3 groove depth is formed between the top seal 102 and the inner wall of the mesh hole, so as to facilitate the outer covering layer 4 to be connected with the silencer bracket 1 to form a whole when molding. Furthermore, bolts, bolt hooks and other bolting parts can be set on the inner wall of the mesh hole to strengthen the bolting effect with the outer covering layer 4.

[0052] The outer covering layer 4 in this embodiment is a structural smoothing layer of the wall, preferably cement mortar; the outer covering layer 4 covers the structural grid 2 to prevent cracking, on the one hand serving as the concrete structure of the wall, and on the other hand facilitating subsequent putty coating.

[0053] Further, please combine Figure 6 and Figure 7 , a mounting tube 11 is provided at the grid node convergence of the grid holes on the grid plane bracket, and some of the multiple mounting tubes 11 are implemented to assist the installation of the structural grid 2, and some are implemented to assist the connection of the connecting piece 3. This is a preferred implementation of this embodiment, and the position of the mounting tube 11 is not necessarily at the grid node convergence of the grid holes. When the structure of the silencer bracket 1 is a waffle structure, the position of the mounting tube 11 can also be at any position of the silencer bracket 1.

[0054] In this embodiment, there are multiple installation tubes 11 , which are respectively located at the grid nodes of the grid holes. The structure thereof can be integrally injection-molded by the silencer bracket 1 .

[0055] In this embodiment, there are multiple installation tubes 11 , which are mainly used to assist in the installation of the structural grid 2 and the connection and bearing of the connecting members 3 .

[0056] For details, please combine Figure 3 , Figure 4 and Figure 6 The two ends of the connector 3 are connected and installed on the mounting tubes 11 of the two sets of grid plane brackets at opposite positions. Further, the connector 3 includes a positioning pad 31 and a mounting plug rod 32. The positioning pad 31 has a through hole, and the mounting plug rod 32 is inserted through the through hole. The positioning pad 31 is padded between the two sets of silencer brackets 1 for positioning, and the two ends of the mounting plug rod 32 extend and are inserted and installed in the mounting tubes 11 of the two sets of silencer brackets 1. The mounting plug rod 32 and the mounting tube 11 are installed by friction or can be further assisted by gluing.

[0057] See also Figure 7 and Figure 8 The present embodiment further includes a buckle 5, which is inserted into the mounting tube 11 and presses the mounting structure grid 2 onto the silencer bracket 1. Preferably, the buckle 5 is a double-ended buckle, with both ends inserted into the two mounting tubes 11, and the middle portion presses the mounting structure grid 2 onto the silencer bracket 1.

[0058] Since the installation rod 32 and the buckle 5 are inserted into the installation tube 11 in opposite directions, the installation tube 11 for the installation rod 32 can be a through tube, or at least the opening faces the installation rod 32; while the installation tube 11 for the buckle 5 has an opening facing the buckle 5 and the other end is a closed end.

[0059] Noise in life is generally low- to medium-frequency noise. As a preferred implementation in this embodiment, the resonance silencing particles 103 are preferably particles with different vibration frequencies. The resonance frequencies of particles of various sizes cover the low- to medium-frequency bands, so as to play a better role in resonance damping and silencing. Furthermore, the resonance silencing particles 103 are mainly resin particles with thermal insulation properties. It should be noted that the resonance silencing particles 103 in the silencing chamber 100 in this embodiment should not fill the chamber, and should ensure that vibration can be formed. A concave and convex echo wall surface can also be formed on the inner wall of the silencing chamber 100, thereby further reducing the energy of the sound and thus better silencing.

[0060] It should be noted that when the energy of sound passes through the wall, it is consumed by the resonance of the resonant sound-absorbing particles 103, thereby forming a sound-absorbing effect. After the sound is converted and transmitted through different media, it is further consumed and isolated in the air layer, further improving the sound-absorbing effect. It also makes the sound transmitted relatively from the two groups of sound-absorbing brackets 1 of the wall be mostly eliminated in the air layer and will not be transmitted to each other.

[0061] Beneficial effects of this embodiment: The present invention achieves the purpose of light weight and good sound insulation effect by setting up a silencer bracket and a structural grid, combining resonant silencer particles and a sound insulation air layer. Specifically, the wall has a reasonable structure and is easy to install, can effectively isolate noise in the medium and low frequency bands, and has good light weight and construction convenience, and is suitable for prefabricated buildings.

[0062] By optimizing the design of the silencer chamber and connectors, the sound insulation effect and overall structural stability of the wall are further improved, ensuring the convenience of the wall during construction and the excellent performance of the final product.

[0063] The honeycomb grid structure of the silencer bracket has a large structural bearing capacity while maintaining a lightweight system, and can withstand the load of the surface cement mortar (outer covering).

[0064] Resonance sound insulation has a greater sound insulation effect, which subverts the traditional theory of sound insulation relying on material density, and can achieve greater sound insulation in thinner walls.

[0065] The presence of a soundproof air layer (air layer) further enhances the sound insulation effect.

[0066] The existence of the structural grid ensures that the cement mortar outer covering of the wall is not prone to cracking.

[0067] An embedded groove is formed outside the honeycomb-shaped silencer chamber to store the cement mortar outer covering layer, thereby preventing the cement mortar from sliding and increasing the convenience of construction.

[0070] For details, please refer to Figure 5~Figure 8 The purpose of the silencer bracket 1 is to provide a silencer chamber 100 and can provide auxiliary structural support for the wall.

The material can be a polymer material, such as FRP material, etc., and the silencer bracket 1 is integrally formed by injection molding. The top seal 102 and the bottom seal 101 are made of polymer insulation material. Furthermore, the bottom seal 101 is preferably made of the same material as the silencer bracket 1, and the top seal 102 is preferably made of a film material.

[0072] In order to facilitate the subsequent molding of the outer covering layer 4, the top seal 102 is preferably set at the half-height position 105 or 1 / 3 of the hole depth in the mesh hole, and an embedding groove 104 of half height or 2 / 3 groove depth is formed between the top seal 102 and the inner wall of the mesh hole, so as to facilitate the outer covering layer 4 to be connected with the silencer bracket 1 to form a whole when molding. Furthermore, bolts, bolt hooks and other bolting parts can be set on the inner wall of the mesh hole to strengthen the bolting effect with the outer covering layer 4.

As a preferred implementation in this embodiment, the resonance silencing particles 103 are preferably particles with different vibration frequencies. The resonance frequencies of particles with various particle sizes cover the low- to medium-frequency bands, thereby achieving a better resonance silencing effect. Furthermore, the resonance silencing particles 103 are mainly resin particles with heat-insulating properties.

[0078] It should be noted that the resonant silencing particles 103 in the silencing chamber 100 in this embodiment should not fill the chamber, but should ensure that vibration can be formed. A concave and convex echo wall surface can also be formed on the inner wall of the silencing chamber 100 to further reduce the energy of the sound and thus better muffle the sound.

[0079] S100: Arranging a structural grid 2 on the outer side of the surface of the silencer bracket 1 to form a prefabricated part.

[0080] In the present embodiment, the material of the structural grid 2 is not limited, and is preferably a steel wire mesh; further preferably, it can be a flat steel wire mesh or a corrugated steel wire mesh.

Preferably, the buckle 5 is a double-ended buckle, with both ends inserted into the two mounting tubes 11, and the middle portion presses the mounting structure grid 2 onto the silencer bracket 1.
