[0023] Embodiment 1

[0024] like Figure 1-3 As shown, the utility model provides a composite sound insulation wall structure that is easy to construct, including a fixed keel 1, the fixed keel 1 is fixedly installed on the inner side of the wall 3, and a connecting keel 2 is arranged on the outer side of the fixed keel 1, and the fixed keel 1 and the connecting keel 2 are both composed of transverse steel purlins and vertical steel purlins cross-fixed. Bolts are used to fix the transverse steel purlins and the vertical steel purlins, and the transverse steel purlins are arranged close to the wall 3 and fixed to the inner side of the wall 3 by expansion screws.

[0025] The fixed keel 1 and the connecting keel 2 are connected by C-shaped steel 6. The connection between the fixed keel 1, the connecting keel 2 and the C-shaped steel 6 is provided with a connection seat 10. During installation, the C-shaped steel 6 can be fixedly connected between the fixed keel 1 and the connecting keel 2 through the connection seat 10. A first through hole is provided at both ends of the C-shaped steel 6. The connection seat 10 is fixedly welded at the intersection of the horizontal steel purlin and the vertical steel purlin. The connection seat 10 is provided with a second through hole 11 of the same size as the first through hole. After the C-shaped steel 6 is inserted into the connection seat 10, the first through hole and the second through hole 11 are ensured to be concentric. Fixing bolts can be inserted into the first through hole and the second through hole 11 to achieve the connection between the fixed keel 1 and the connecting keel 2. A connection seat 10 is provided within the unit 3m*3m range to ensure a stable connection between the fixed keel 1 and the connecting keel 2.

[0026] The inner and outer sides of the connecting keel 2 are respectively provided with a sound absorbing component and a sound insulating component, and the sound absorbing component is integrally connected to the connecting keel 2. The sound absorbing component includes a rock wool board 4, and the number of the rock wool boards 4 is two. A glass cloth 5 is fixed between the two rock wool boards 4, and the two rock wool boards 4 are fixedly connected by screws. By setting up a rock wool board-glass cloth-rock wool board structure, the noise transmitted into the room from the outside can be effectively eliminated. The rock wool board-glass cloth-rock wool board structure can be assembled in advance before construction. The rock wool board 4 can absorb sound and reduce noise while also playing a good flame retardant role, and the glass cloth 5 has good anti-corrosion and heat preservation effects.

[0027] The rock wool board 4 is provided with threaded holes around it, and the rock wool board 4 is fixed to the inner side of the connecting keel 2 by bolts. The inner side of the connecting keel 2 is provided with fixing holes corresponding to the threaded holes, which can facilitate the fixed installation of the rock wool board 4.

[0028] The length of the C-shaped steel 6 is the same as the thickness of the sound-absorbing component, so as to avoid the distance between the fixed keel 1 and the connecting keel 2 being too large, which would make the wall structure too thick and thus occupy the indoor space. The sound-absorbing component is provided with a C-shaped steel insertion hole to facilitate the fixing and installation of the C-shaped steel 6.

[0029] The sound insulation component is slidably connected to the outer side of the connecting keel 2, and a connecting slot 8 is provided on the outer side of the connecting keel 2, and the sound insulation component is clamped in the connecting slot 8. The sound insulation component includes an aluminum-plastic plate 7, and a connecting key 9 is provided on one side of the aluminum-plastic plate 7 close to the connecting keel 2, and the connecting key 9 can be firmly clamped in the connecting slot 8. Figure 2 Only a single aluminum-plastic panel 7 is shown fixed to the outside of the connecting keel 2 , and two adjacent aluminum-plastic panels 7 are clamped in a connecting clamping groove 8 . This installation method is simple, and finally, sealant is injected between the adjacent aluminum-plastic panels 7 .

[0030] During installation, the connecting key 9 can be inserted into the connecting slot 8, so as to facilitate the fixation of the sound insulation component. Then, the aluminum-plastic panel 7 and the joints with the wall are sealed around it, so that an air layer can be formed between the sound insulation component and the connecting keel 2, thereby achieving better sound insulation effect.

[0031] Therefore, the utility model adopts the above-mentioned easy-to-construct composite sound insulation wall structure, which can effectively improve the sound insulation effect of the wall and facilitate construction and installation.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
