[0020] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides an assembled full sound-absorbing wall, which is installed on the original wall 10. The assembled full sound-absorbing wall includes a plurality of sound-absorbing wall bodies 1 in a quadrilateral shape and arranged in an array. The sound-absorbing wall body 1 includes a facing layer 11 and a sound-absorbing layer 12. The sound-absorbing layer 12 is arranged inside the facing layer 11 and fits the original wall 10. The edge of the surface of the facing layer 11 away from the original wall 10 is recessed with a notch 111, so that the edge of the facing layer 11 is stepped. An installation groove 2 is formed between each adjacent two sound-absorbing wall bodies 1. A fixed support member 3 is arranged in the installation groove 2. The cross section of the fixed support member 3 is a T-shaped structure. The fixed support member 3 is fixedly installed on the original wall 10 and fills the notch 111. The surface of the fixed support member 3 away from the original wall 10 is coplanar with the surface of the facing layer 11 away from the original wall 10. In this embodiment, there are four sound-absorbing wall bodies 1. In specific implementation, the number and size of the sound-absorbing wall bodies 1 can be determined according to the use requirements.

[0022] The facing layer 11 is a box structure with an opening on one side, and the cavity of the facing layer 11 forms an installation cavity 112. The structure of the sound absorbing layer 12 is adapted to the installation cavity 112, so that it can be installed in the installation cavity 112. When the fixing support 3 is installed in place, the position of the facing layer 11 is locked, so that the sound absorbing layer 12 is squeezed and fixed between the facing layer 11 and the original wall 10.

[0023] The facing layer 11 is made of wooden material, and patterns or colors can be printed on its surface as needed; the sound-absorbing layer 12 is made of sound-absorbing materials such as foam cotton or glass wool, which is not limited here.

[0024] The fixed support member 3 includes a support plate 31 and a baffle 32 which are connected to each other, and the two are connected vertically to form a T-shaped structure, wherein the support plate 31 is arranged horizontally, and the baffle 32 is arranged vertically, and the side of the support plate 31 away from the baffle 32 is in contact with the original wall 10 and fixedly installed on the original wall 10, and the support plate 31 is located between two adjacent finishing layers 11 and is in contact with the side wall of the finishing layer 11. The baffle 32 cooperates with the missing groove 111, and when the fixed support member 3 is installed in place, the baffle 32 can be completely filled in the missing groove 111, and the surface of the baffle 32 away from the original wall 10 is coplanar with the surface of the finishing layer 11 away from the original wall 10, therefore, under the action of the fixed support member 3, the empty groove between two adjacent sound-absorbing walls 1 is completely filled, so that the multiple sound-absorbing walls 1 have a "full" effect after assembly, and the surface consistency is good. At the same time, the support plate 31 supports the sound-absorbing wall 1 located above the support plate 31, and the baffle 32 clamps the sound-absorbing wall 1 on the original wall 10. The support plate 31 and the baffle 32 cooperate with each other to lock the sound-absorbing wall 1 on the original wall 10. The above fixing method does not require drilling holes on the sound-absorbing wall 1, nor does it require fixing it to the original wall 10 by gluing, which avoids damage to the sound-absorbing wall 1 and ensures that no residual glue will remain on the original wall 10 during disassembly, so that the surface of the original wall 10 remains clean.

[0025] As a preferred embodiment, a groove 321 is formed inwardly on the outer surface of the baffle 32, and a bolt 33 is installed in the groove 321. The nut of the bolt 33 is located in the threaded mounting port 321. One end of the bolt 33 passes through the support plate 31 and is threadedly connected to the original wall 10, so that the support plate 31 is fixedly installed on the original wall 10 to achieve a fixed connection relationship between the fixed support member 3 and the original wall 10.

[0026] In addition, a plurality of bolts 33 are installed on the same baffle 32 along its length direction, thereby improving the connection stability between the fixed support member 3 and the original wall 10, thereby ensuring that the fixed support member 3 can effectively support and fix the sound-absorbing wall 1, and is reliable to use.

[0027] As a preferred embodiment, a filling plate 34 is fixedly installed in the groove 321, and the outer surface of the filling plate 34 is coplanar with the surface of the facing layer 11 away from the original wall 10. By providing the filling plate 34, on the one hand, the bolts 33 can be shielded, and on the other hand, the surface of the sound-absorbing wall can be free of visible groove structures, and the appearance after installation is consistent and has a good appearance. In specific implementation, the surfaces of the baffle 32 and the filling plate 34 can be coated or attached with a coating with a pattern or color to be consistent with the decorative surface pattern or color of the facing layer 11.

[0028] As a preferred embodiment, the filling plate 34 can be installed in the groove 321 by gluing or other methods.

[0029] In addition, an L-shaped fixing member 4 is provided between the outermost side of the facing layer 11 and the original wall 10. The L-shaped fixing member 4 has two sides perpendicular to each other, one side of which fits in the missing groove 111 to achieve a "full" effect, and the other side fits the original wall 10 and is fixedly connected to the original wall 10, so that the L-shaped fixing member 4 is fixed to the original wall 10. By providing the L-shaped fixing member 4, the outermost side of the facing layer 11 can be fixed, and the fixing strength of the sound-absorbing wall 1 is increased, so that it can be stably installed on the original wall 10. The connection method between the L-shaped fixing member 4 and the original wall 10 is the same as that of the fixed support member 3, and bolts 33 can also be used for connection, and a filling plate 34 is provided to block the groove 321 for installing the bolts 33, which will not be repeated here. In addition, the fixed support member 3 and the L-shaped fixing member 4 can be made of steel material.

[0030] The assembled full sound-absorbing wall of the utility model is provided with a fixed support member 3 between two adjacent sound-absorbing wall bodies 1.
