[0036] The hook plate in the first hanging strip 2 can be directly folded on the main body of the first hanging strip 2 to form a first hole 22 of the same size as the hook plate, and then the folded part can be bent to form an L-shaped hook plate 21, that is, the first plate 211 of the hook plate 21 is fixedly connected to the edge of the corresponding first hole 22 on the main body of the first hanging strip 2, thereby saving manufacturing materials. It is also possible to directly use a plurality of L-shaped hook plates 21 and weld one end of the first plate 211 of the hook plate 21 to the main body of the first hanging strip 2.

[0037] The second hanging strip 5 buckle plate 51 can also choose to use the same process as the second hanging strip 2, that is, a third hole 52 of the same size as the buckle plate is directly folded on the main body of the second hanging strip 5, and then the folded part is bent to form an L-shaped buckle plate 51, that is, the first plate 511 of the buckle plate 51 is fixedly connected to the edge of the corresponding third hole 52 on the main body of the second hanging strip 5, or a plurality of L-shaped buckle plates 51 can be directly used, and one end of the first plate 511 of the buckle plate 51 is welded to the main body of the second hanging strip 5. In actual application, the second hanging strip 2 and the fifth hanging strip 5 can be made by the same process or by different production methods.

[0038] The hanging strip hanging member 4 is a hollow square plate structure, which realizes the method of hanging the first hanging wall panel 3 and the second hanging strip 5 to fix the second hanging wall panel 6. An elastic pad 41 is provided on the first side of the hanging strip hanging member 4 to enhance the sound insulation and heat insulation performance of the hanging multi-layer sound insulation wall structure. The size of the elastic pad 41 may be slightly larger than or equal to the size of the first side of the hanging strip hanging member 4. A plurality of hanging holes 42 are provided on the second side of the hanging strip hanging member 4 for hanging the second hanging strip 5. A second adhesive pad 43 is provided at one end of the plurality of hanging holes 42. The structure of the second adhesive pad 43 may be the same as the structure and material of the first adhesive pad 122, and the size of the second adhesive pad 43 is adapted to the size of the hanging hole 42.

[0039] The through holes 121 on the two flanges of the vertical keel are also used to hang the first hanging strip 2 to combine with the first wall hanging board 3. The hanging holes 42 on the hanging strip hanging piece are used to hang the second hanging strip 5 to combine with the second wall hanging board 6. The first hanging buckle plate 21 is adapted to the through holes 121 on the flange of the vertical keel, and the second hanging buckle plate 51 is adapted to the hanging holes 42 on the hanging strip hanging piece. The size of the through holes 121 on the two flanges of the vertical keel 12 is customized to be the same as the size of the hanging holes 42 provided on the other side of the hanging strip hanging piece 4, so that the size of the first hanging buckle plate 21 is also the same as that of the second hanging buckle plate 51. At the same time, the through holes 121 on the two flanges of the vertical keel 12 are adjusted to the same size as that of the hanging holes 42 provided on the other side of the hanging strip hanging piece 4. The spacing between adjacent through holes and the spacing between adjacent hanging holes of the plurality of hanging holes 42 provided on the other side of the hanging board strip hanging part 4 can also be customized to be the same. Furthermore, the first hanging board strip 2 and the second hanging board strip 5 have the same outer dimensions, that is, the first hanging board strip 21 and the second hanging board strip 51 are customized to have exactly the same structure, thereby reducing the time spent on classifying and processing different hanging board strips during construction. According to actual applications in construction, the first hanging board strip 2 and the second hanging board strip 5 can also be set to different structures for application. For example, in order to increase the stability of the wall panel hanging, the bonding area between the second hanging board strip 51 and the second wall panel 6 can be increased, that is, the size of the main board of the second hanging board strip 51 can be increased.

[0040] Referring to the diagram, a plurality of second holes can also be provided on the web of the vertical keel 12, and a plurality of C-shaped snap plates 123 are provided at positions corresponding to the plurality of second holes. The C-shaped snap plates 123 include a ridge plate 1232 and two bent plates 1231 formed by vertically bending in the same direction on both sides of the ridge plate. The two bent plates 1231 are fixedly connected to the edges of the corresponding second holes on the web of the vertical keel. The C-shaped snap plates provide an interface for hanging other accessories during use to meet the use requirements in construction projects.

[0041] The structures of the several protrusions on the two flanges of the transverse keel 11 can be rectangular structures or other structures. In the present invention, the protrusions 111 are set to be semi-cylindrical structures, which can reduce the friction during the clamping process of the vertical keel and facilitate installation. The spacing between the protrusions 111 is set to be equidistant. On the one hand, it is convenient to calculate the length between certain sections of the transverse keel, and on the other hand, it makes the manufacturing process simple. The spacing between the protrusions 111 can also be set to be unequal according to the needs of actual applications.

[0042] The material of the first wall panel 3 and the second wall panel 6 can be gypsum wall panels or one of them can be gypsum wall panels. Gypsum board has good sound absorption and sound insulation performance, and can effectively absorb noise to enhance the sound insulation and sound absorption performance of the hanging multi-layer sound insulation wall structure. According to construction needs, the wall panels in the hanging multi-layer sound insulation wall structure can also be made of other materials, such as fiberboard, paper gypsum board, plywood, calcium plastic board, plastic aluminum board, fiber cement board and other lightweight thin boards.

[0043] The number of the keel connection structure 1, the first hanging board slat 2, the hanging board slat hanging parts 4 and the second hanging board slat 5 in the hanging multi-layer sound insulation wall structure needs to be determined according to the construction area. The number of layers of the wall panels is not limited to two layers, that is, it not only includes the first wall panels and the second wall panels, but also includes more than two layers of third wall panels, fourth wall panels, etc., so that the sound insulation effect will be increased, but the thickness of the hanging multi-layer sound insulation wall structure will also increase. The specific choice of the thickness of the hanging multi-layer sound insulation wall structure depends on the size of the space and personal needs. The connection method between the wall panels is to connect the hanging board slat hanging parts with the hanging board slats. It is convenient to install and disassemble, easy to operate, improves construction efficiency, and shortens the construction period.

[0044] Figure 5A structural schematic diagram of a specific embodiment of the edge strip 7 is shown, where the edge strip 7 includes a main board 71, a first side panel 72, and a second side panel 73. The first end of the first side panel 72 and the first end of the second side panel 73 are vertically connected to the end of the main board 71, and the second end of the first side panel 72 and the second end of the second side panel 73 have a plurality of groups of fixed teeth 74 bent toward each other, with a certain spacing reserved between each group of fixed teeth, for example, a distance within the range of 50-150 mm, and the length of the fixed teeth is less than or equal to the thickness of the wall panel to prevent leakage from the surface of the wall panel, and the width of the first side panel 72 is less than the width of the second side panel 73, so that the side edge of the wall panel is in contact with the main board 71 of the edge strip, and then the fixed teeth 74 of the first side panel and the fixed teeth 74 of the second side panel are vertically pressed into the wall panel through an extrusion process to fix them, so as to protect the side edges. In the present invention, edge strips 7 can be provided on the sides of the first wall panel 3 and the second wall panel 6 at the same time, or on the side of one of the wall panels, to protect the sides of the wall panels from damage and extend the service life of the wall panels. According to needs, edge strips can be provided on all sides of the wall panels to protect the sides of the panel walls from damage, thereby extending the service life of the hung multi-layer sound insulation wall structure.

[0045] In summary, the hanging multi-layer sound insulation wall structure of the present invention can connect the vertical keel with the horizontal keel in a fixed manner by clamping, which is convenient to install and simple to operate, saving the time of measuring the keel and drilling and nailing for connection in the traditional way during the construction process, and greatly improving the construction efficiency. In the hanging multi-layer sound insulation wall structure, the wall panels and the keel are connected by hanging the hanging board strips, and the wall panels are fixed by hanging board strip hanging parts and hanging board strips, which replaces the wall panels and the wall panels and the wall panels and the keel using self-tapping screws or gluing. The installation process is simple and easy to operate, thereby improving the construction efficiency. At the same time, the hanging multi-layer sound insulation wall structure is properly maintained to extend the service life of the hanging multi-layer sound insulation wall structure.
