Description

Technical Field

[0001] This application relates to the field of architecture, and in particular to a composite constrained damping sound insulation structure. Background Technology

[0002] The descriptions in this section provide background information related to this disclosure only and do not constitute prior art. In my country, the thickness of commonly used reinforced concrete floor slabs is only 10-12 cm, with a weighted standardized impact sound pressure level as high as 80 dB, far below the standard, necessitating improvement through additional sound insulation measures.

[0003] Current sound insulation solutions for building floors include sound-absorbing mortar and sound-absorbing coatings, but both have certain drawbacks. Sound-absorbing mortar requires thick-layer application, and its high rigidity results in poor sound insulation and a tendency to form sound bridges. While sound-absorbing coatings offer advantages such as thin-layer application and high-frequency sound insulation, they are less effective at blocking low-frequency impact sounds (such as footsteps). Therefore, improving the sound insulation effect of building floors is crucial. Summary of the Invention

[0004] In view of this, this application provides a composite constrained damping sound insulation structure that can improve the sound insulation effect of the floor.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A composite constrained damping sound insulation structure, characterized in that it comprises a floor, a wall, wall columns, a sound-insulating coating layer, a sound-insulating mortar layer, an adhesive layer, and a finishing material layer; the sound-insulating coating layer comprises a first part and a second part integrally connected, the first part of the sound-insulating coating layer is disposed on the floor, the second part is disposed on the wall and wall columns, the sound-insulating mortar layer is disposed on the first part of the sound-insulating coating layer, and the perimeter of the sound-insulating mortar layer is connected to the second part, the height of the second part is the same as the height of the upper surface of the sound-insulating mortar layer, the adhesive layer is disposed on the sound-insulating mortar layer, and the finishing material layer is disposed on the adhesive layer.

[0007] The aforementioned composite constrained damping sound insulation structure of this application forms a constrained damping sound insulation structure by setting a sound-insulating mortar layer on a sound-insulating coating layer. This structure utilizes the inconsistent deformation of the sound-insulating mortar layer and the sound-insulating coating layer to enhance the shear deformation of the sound insulation layer, thereby further improving the sound insulation effect. Moreover, the sound-insulating coating has high bonding strength, and the continuous, seamless sound-insulating coating layer formed between it and the floor, walls, and columns can effectively block the sound bridging effect that may be caused by the sound-insulating mortar layer, thus improving the sound insulation effect.

[0008] In some embodiments, the thickness of the first portion of the sound-insulating coating layer is 1-5 mm, the thickness of the second portion is 1-5 mm, the thickness of the sound-insulating mortar layer is 10-30 mm, and the thickness of the adhesive layer is 5-10 mm.

[0009] The sound insulation coating layer can be made of Three Trees sound insulation coating SGF850; the sound insulation mortar layer can be made of Three Trees sound insulation mortar SNN860.

[0010] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0011] 1. Sound-insulating coatings and mortars, when used alone, both offer some sound insulation, but each has limitations. This application addresses this by adding a sound-insulating mortar layer over a sound-insulating coating layer, creating a constrained damping sound insulation structure. This structure utilizes the inconsistent deformation of the sound-insulating mortar and coating layers to enhance the shear deformation of the sound insulation layer, further improving the sound insulation effect. (Compared to using sound-insulating coatings or mortars alone, the constrained damping sound insulation structure combining sound-insulating coatings and mortars further enhances the sound insulation effect.)

[0012] 2. Due to the low bonding strength of sound-insulating mortar, its direct contact with walls and columns makes it prone to hollow areas and gaps, which can form sound bridges and reduce the sound insulation effect. In contrast, sound-insulating coatings have high bonding strength, and the continuous, seamless sound-insulating coating layer formed between the coating and the floor, walls, and columns can effectively block the sound bridge effect that may be caused by the sound-insulating mortar layer, thus improving the sound insulation effect.

[0013] 3. Sound insulation coatings can be applied by spraying, troweling, or smearing. The application methods are simple and efficient. By being placed between floors, walls, and columns to form a continuous and seamless sound insulation coating layer, the sound bridge effect of the sound insulation mortar layer can be effectively blocked, making the elimination of sound bridges in the sound insulation mortar simple and low-cost.

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0017] See Figure 1This application provides a composite constraint damping sound insulation structure, including a floor 1, a wall 2, wall columns, a sound insulation coating layer 3, a sound insulation mortar layer 4, an adhesive layer 5, and a finishing material layer 6. The sound insulation coating layer 3 includes a first part 31 and a second part 32 integrally connected. The first part 31 of the sound insulation coating layer 3 is disposed on the floor 1, and the second part 32 is disposed on the wall 2 and wall columns. The sound insulation mortar layer 4 is disposed on the first part 31 of the sound insulation coating layer 3, and the perimeter of the sound insulation mortar layer 4 is connected to the second part 32. The height of the second part 32 is the same as the height of the upper surface of the sound insulation mortar layer 4. The adhesive layer 5 is disposed on the sound insulation mortar layer 4, and the finishing material layer 6 is disposed on the adhesive layer 5.

[0018] This composite constrained damping sound insulation structure forms a constrained damping sound insulation structure by setting a sound-insulating mortar layer on top of a sound-insulating coating layer. This structure utilizes the inconsistent deformation of the sound-insulating mortar layer and the sound-insulating coating layer to enhance the shear deformation of the sound insulation layer, further improving the sound insulation effect. Moreover, the sound-insulating coating has high bonding strength, and the continuous, seamless sound-insulating coating layer formed between it and the floor, walls, and columns effectively blocks the sound bridging effect that may be caused by the sound-insulating mortar layer, improving the sound insulation effect.

[0019] The thickness of the first part 31 of the sound insulation coating layer 3 is 1-5mm, the thickness of the second part 32 is 1-5mm, the thickness of the sound insulation mortar layer 4 is 10-30mm, and the thickness of the adhesive layer 5 is 5-10mm.

[0020] The sound insulation coating layer can use Three Trees SGF850 sound insulation coating; the sound insulation mortar layer can use Three Trees SNN860 sound insulation mortar. The bonding layer 5 can use tile adhesive to connect the sound insulation mortar layer and the finishing material layer.
