[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 A sound insulation structure for energy-saving buildings includes a base floor slab 1, a concrete ring beam 5 cast on the upper side of the base floor slab 1, a sound insulation and vibration damping composite layer at the upper end of the base floor slab 1, a vacuum heat insulation and sound insulation module at the upper end of the sound insulation and vibration damping composite layer, and a decorative layer 3 at the upper end of the vacuum heat insulation and sound insulation module. The decorative layer 3 is made of wood-grain bricks.

[0023] The sound insulation and vibration damping composite layer includes a honeycomb substrate 7, on which honeycomb holes 12 are arranged at equal intervals, and springs 11 are arranged at equal intervals on the upper surface of the honeycomb substrate 7, with a damping rubber block 10 arranged at the upper end of each spring 11.

[0024] The lower end face of the honeycomb substrate 7 is provided with a groove 9, and the upper end face of the base floor 1 is provided with a tooth 6. The tooth 6 and the groove 9 mesh with each other to improve the stability of the honeycomb substrate 7 placed on the upper end of the base floor 1.

[0025] The vacuum thermal insulation and sound insulation module includes two low-emissivity coated fiberglass panels 4, and aluminum alloy frames 2 are provided on the sides of the two low-emissivity coated fiberglass panels 4. The aluminum alloy frames 2 abut against the top of the concrete ring beam 5.

[0026] After the vacuum heat insulation and sound insulation module is placed on the top of the sound insulation and vibration damping composite layer, the spring 11 is in a fully compressed state, and the aluminum alloy frame 2 abuts against the top of the concrete ring beam 5. Through the combination of the vacuum heat insulation and sound insulation module and the sound insulation and vibration damping composite layer, the honeycomb holes 12 and the two low-emissivity coated glass fiber panels 4 effectively reduce the transmission of sound, and the space supported by the honeycomb holes 12, the spring 11 and the damping rubber block 10 reduces the transmission of heat, thus achieving a good sound insulation and heat insulation effect.

[0028] Aerogel particle columns 8 are used to support the vacuum structure between two low-emissivity coated glass fiber plates 4. As a low-stiffness, high-damping material, aerogel particle columns 8 can significantly attenuate the solid sound energy transmitted through the glass plates.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
