[0002] With the continuous development of social economy, people's cultural and spiritual needs are getting higher and higher. Large public buildings such as theaters and cultural entertainment have sprung up all over the country. When such buildings are used for entertainment and cultural activities, they often consider the large short-term flow of people. In order to meet their fire protection, smoke exhaust, ventilation and other needs, they must be equipped with more large mechanical equipment. These mechanical equipment often produce large vibrations and noises during operation, which will seriously affect the use of theater buildings;

[0003] After searching, the existing patent (application number: CN 213868488 U) discloses a sound-absorbing and vibration-reducing floating floor structure for large equipment rooms in public buildings, including a concrete bottom plate, a floating foundation structure, an equipment concrete vibration-reducing foundation and a hoop concrete.

The utility model solves the problem of vibration sound transmission of the equipment foundation, so that the theater can achieve the designed use effect. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] At present, in order to solve the problem of sound absorption and vibration reduction of large equipment, rubber vibration isolation pads are placed under the legs and on the equipment foundation during equipment installation to reduce the vibration caused by the operation of the equipment.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] As attached Figure 1-4The sound-absorbing and vibration-reducing floating floor structure for large equipment rooms in public buildings shown in the figure comprises a wall 1, a noise reduction and vibration-reducing mechanism 2 is embedded and installed inside the wall 1, and the noise reduction and vibration-reducing mechanism 2 comprises a floor body 3, a concrete floor 4, a first waterproof layer 5, a floating vibration-isolating pad 6, a vibration-reducing pad 7, a sound-absorbing panel 8, a second waterproof layer 9, a steel plate layer 10, and sound-insulating cotton 12; a floor body 3 is fixedly installed on one side of the wall 1, a concrete floor 4 is laid on the bottom of the floor body 3, a first waterproof layer 5 is laid on the top of the concrete floor 4, a floating vibration-isolating pad 6 is laid on the top of the first waterproof layer 5, a vibration-reducing pad 7 is embedded and installed inside the floating vibration-isolating pad 6, a sound-absorbing panel 8 is laid on the top of the vibration-reducing pad 7, a second waterproof layer 9 is laid on the top of the floating vibration-isolating pad 6, a steel plate layer 10 is installed on the top of the second waterproof layer 9, and sound-insulating cotton 12 is embedded and installed inside the steel plate layer 10.

[0026] Among them: by laying the first waterproof layer 5 and the second waterproof layer 9 inside the floor body 3, moisture penetration and damage to the underlying structure are effectively prevented, and the floating seismic isolation pad 6 is provided with a shock-absorbing pad 7 and a sound-absorbing board 8. The floating seismic isolation pad 6 can effectively isolate and absorb the vibration and noise generated during the operation of the equipment, and significantly reduce the propagation of vibration and noise to the surrounding environment. The shock-absorbing pad 7 further enhances the vibration reduction effect, ensuring that the impact of the equipment on the floor is effectively alleviated during operation. The coordinated use of the sound-absorbing board 8 and the sound insulation cotton 12 can absorb and reduce the noise during the operation of the equipment, and improve the quietness of the internal environment of the building. The steel plate 10 provides a stable installation foundation for the equipment, while enhancing the bearing capacity and stability of the entire floor.

[0027] Embodiment 2

[0028] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below:

[0029] like Figure 4 As shown, as a preferred embodiment; a lightweight keel 11 is embedded and installed inside the steel plate layer 10. Furthermore, the lightweight keel 11, as a skeleton structure, can effectively enhance the overall stability and load-bearing capacity of the steel plate layer 10. In a large equipment room, since the equipment itself may generate large vibrations and impacts, the addition of the lightweight keel 11 can ensure that the entire ground structure is more stable and reduce deformation or damage caused by vibration. The combination of the lightweight keel 11 with the steel plate layer 10, sound insulation cotton 12 and other materials can form a relatively closed space structure, which helps to isolate the spread of noise.

[0030] like Figure 4As shown, as a preferred embodiment; a wear-resistant ground layer 13 is laid on the top of the steel plate layer 10. Further, the wear-resistant ground layer 13 is usually made of a high-strength, high-wear-resistant material to improve the wear resistance of the floor body 3.

[0031] The working process of the utility model is as follows:

[0032] When the sound-absorbing and vibration-reducing floating floor structure for large equipment rooms in public buildings is used in the later stage, the first waterproof layer 5 and the second waterproof layer 9 are laid inside the floor body 3 to effectively prevent moisture from penetrating and damaging the lower structure, and the floating seismic isolation pad 6 is provided with a shock-absorbing pad 7 and a sound-absorbing board 8. The floating seismic isolation pad 6 can effectively isolate and absorb the vibration and noise generated when the equipment is running, and significantly reduce the transmission of vibration and noise to the surrounding environment. The shock-absorbing pad 7 further enhances the vibration reduction effect, ensuring that the impact of the equipment on the floor is effectively alleviated when it is running. The coordinated use of the sound-absorbing board 8 and the sound insulation cotton 12 can absorb and reduce the noise when the equipment is running, and improve the interior of the building. The quietness of the environment, the steel plate 10 provides a stable installation foundation for the equipment, and at the same time enhances the bearing capacity and stability of the entire floor. The lightweight keel 11, as a skeleton structure, can effectively enhance the overall stability and bearing capacity of the steel plate layer 10. In large equipment rooms, since the equipment itself may produce large vibrations and impacts, the addition of the lightweight keel 11 can ensure that the entire ground structure is more stable and reduce deformation or damage caused by vibration. The combination of the lightweight keel 11 with the steel plate layer 10, sound insulation cotton 12 and other materials can form a relatively closed space structure, which helps to isolate the spread of noise. This is the working process and working principle of the device.
