Description

Technical Field

[0001] The utility model relates to the technical field of partition walls, and more particularly to a partition wall with good sound insulation effect. Background Art

[0002] Partition walls are used to separate the interior spaces of buildings. Partition walls are generally non-load-bearing and have different requirements for partition walls in rooms with different functions. Partition walls are very common in interior decoration projects. Depending on the material and construction methods, they are suitable for different areas and have different properties. Light steel keel gypsum board partition walls are often used to separate offices and guest rooms. The construction is convenient and fast, and the load on the floor is reduced. However, during the use of existing interior partition walls, most of them only use gypsum board to block sound, resulting in poor sound insulation effect, which is difficult to meet the privacy protection needs of indoor personnel and affects the reliability of the partition wall. In view of this, we propose a partition wall with good sound insulation effect to solve the above problems. Utility Model Content

The light steel keel rib assemblies 2 divide the light steel keel frame 1 into a plurality of sound insulation cavities 101. The interior of the sound insulation cavity 101 is filled with a sound insulation cotton layer 3. The sound is absorbed by the sound insulation cotton layer 3 in each sound insulation cavity 101, which is beneficial to reducing the penetrability of the sound. Damping sound insulation felt layers 4 are fixedly bonded to both sides of the light steel keel frame 1. The damping sound insulation felt layers 4 on both sides of the light steel keel frame 1 further reduce the transmission of sound. The side of the damping sound insulation felt layer 4 is fixedly bonded with a fireproof cloth layer 5. The fireproof cloth layer 5 is used to ensure the overall fire resistance of the partition wall. The side of the fireproof cloth layer 5 is provided with a double-layer paper-faced gypsum board 6, and the double-layer paper-faced gypsum board 6 is fixedly installed on the light steel keel frame 1 by a special screw assembly 7.

[0021] Among them, such as Figure 4 As shown, the light steel keel rib assembly 2 includes two light steel keel ribs symmetrically arranged, and the opposite end faces of the two light steel keel ribs are fixedly connected. The use of each light steel keel rib can ensure the overall structural strength of the light steel keel frame 1.

[0022] Among them, such as Figure 2 As shown, the sound insulation cotton layer 3 is a component made of polyester fiber, which makes the sound insulation cotton layer 3 have a good sound absorption effect. The thickness of the sound insulation cotton layer 3 is 75 mm.

[0023] Among them, such as Figure 3 As shown, the special screw assembly 7 includes four fastening screws, and the four fastening screws are distributed in a rectangular shape, thereby achieving the purpose of ensuring the installation stability of the double-layer gypsum board 6.

[0024] Among them, such as Figure 3 As shown, a countersunk groove 601 is provided on the side of the double-layer gypsum board 6 at a position corresponding to the fastening screw, and the end cap of the fastening screw is located in the countersunk groove 601, so that the end cap of the fastening screw can be hidden.

[0025] Among them, such as Figure 4 As shown, the fireproof cloth layer 5 is a component made of glass fiber, which makes the fireproof cloth layer 5 have a good fireproof effect. The thickness of the damping sound insulation felt layer 4 and the fireproof cloth layer 5 is 2 mm.

[0026] The working principle of this utility model:

[0027] During use, the light steel keel rib assembly 2 is used to divide the light steel keel frame 1 into several sound insulation cavities 101, and the interior of the sound insulation cavity 101 is filled with a sound insulation cotton layer 3. The sound is absorbed by the sound insulation cotton layer 3 in each sound insulation cavity 101, which is beneficial to reducing the penetrability of the sound. The damping sound insulation felt layer 4 is fixedly bonded on both sides of the light steel keel frame 1. The damping sound insulation felt layer 4 on both sides of the light steel keel frame 1 further reduces the transmission of sound, thereby effectively blocking the sound, so that the partition wall has a good sound insulation effect, and the fireproof cloth layer 5 is fixedly bonded on the side of the damping sound insulation felt layer 4, and the fireproof cloth layer 5 is used to ensure the overall fire resistance of the partition wall.
