Description

Technical Field

[0001] This utility model belongs to the field of building decoration technology, and in particular relates to a sound-insulating and vibration-damping keel partition wall for buildings. Background Technology

[0002] As a new type of building structure, partition walls are widely used in various environments such as stations, hotels, offices, and shopping malls to divide the space within a building to meet people's different needs. In related technologies, partition walls are often made of light steel keel, which has the advantages of being lightweight, easy to construct, and having a long service life.

[0003] However, when existing keel partition walls are in use, the sound waves transmitted to the partition walls will cause the light steel keel to vibrate, and transmit the noise into the space separated by the partition walls. In places with severe noise and vibration, it will affect people's daily work, study, rest and entertainment, and may even cause harm to human health. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sound-insulating and vibration-damping keel partition wall for buildings, and the technical solution adopted is as follows:

[0005] A sound-insulating and vibration-damping keel partition wall for buildings includes a main keel wall connected to a wall body, and a secondary keel wall connected to one side of the main keel wall. The main keel wall and the secondary keel wall have the same structure, both consisting of three layers of sound insulation panels. A cavity is provided between adjacent sound insulation panels, and a connector is provided in each cavity of adjacent sound insulation panels. The positions of the connectors in different cavities are alternately arranged, and sound insulation cotton is filled in the cavities of adjacent sound insulation panels.

[0006] Furthermore, edge keels are provided at the connection points between the main keel wall and the secondary keel wall, as well as at the connection points between the main and secondary keel walls and any other wall.

[0007] Furthermore, the main and secondary keel walls are connected to the edge keels with screws, and the walls are connected to the edge keels with fixing bolts. Sound insulation pads are installed at the connection points between the edge keels and the main and secondary keel walls.

[0008] Furthermore, when splicing the main keel wall and the secondary keel wall, an opening is made in the secondary keel wall for the main keel wall to be embedded, and then fixed by the edge keel, making the connection tighter and the whole more solid.

[0009] Furthermore, the connector includes a vertical keel and a reinforcing sleeve, with the reinforcing sleeve located inside the vertical keel. The connectors, which are alternately arranged within the three layers of sound insulation panels, can form a sandwich structure for the sound insulation panels.

[0010] Furthermore, the vertical keel and the reinforcing sleeve are connected to the sound insulation plates on both sides by screws.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The connectors alternately arranged within the three layers of sound insulation panels in this invention can form a sandwich structure, eliminating the need for a through-beam frame, thus reducing material usage. Furthermore, the double cavity formed between the three layers of sound insulation panels provides better sound insulation compared to a single cavity structure. The generated noise and vibration can also be absorbed by the sound insulation cotton filling the spaces between the sound insulation panels and adjacent sound insulation panels, resulting in better performance.

[0023] As attached Figure 1-7 As shown.

[0024] A sound-insulating and vibration-damping keel partition wall for building includes a main keel wall 2 connected to a wall 1, and a secondary keel wall 3 connected to one side of the main keel wall 2. The main keel wall 2 and the secondary keel wall 3 have the same structure, both consisting of three layers of sound insulation panels. A cavity is provided between adjacent sound insulation panels, and a connector is provided in the cavity of adjacent sound insulation panels. The positions of the connectors in different cavities are alternately arranged, and sound insulation cotton is filled in the cavity of adjacent sound insulation panels.

[0025] Edge keel 6 is provided at the connection between the main keel wall 2 and the secondary keel wall 3, as well as at the connection between the main and secondary keel walls and any wall. The main and secondary keel walls are connected to the edge keel 6 by screws, and the wall 1 is connected to the edge keel 6 by fixing bolts 62. Sound insulation pads 61 are provided at the connection between the edge keel 6 and the main and secondary keel walls.

[0026] When the main keel wall 2 and the secondary keel wall 3 are spliced, an opening is made in the secondary keel wall 3 for the main keel wall 2 to be embedded, as shown in the attached figure. Figure 2 , 5 As shown.

[0027] The working principle of this technical solution is as follows: the connectors alternately arranged in the three layers of sound insulation panels can form a sandwich structure, eliminating the need for a through keel, reducing material usage, and the double cavity formed between the three layers of sound insulation panels has a better sound insulation effect than a single cavity structure; the generated noise and vibration can also be absorbed by the sound insulation panels and the sound insulation cotton inside the sound insulation panels, resulting in better performance.

[0028] The connector includes a vertical keel 4 and a reinforcing sleeve 5. The reinforcing sleeve 5 is located inside the vertical keel 4. The vertical keel 4 and the reinforcing sleeve 5 are connected to the sound insulation panels on both sides by screws, making the connection between adjacent sound insulation panels more secure and able to withstand greater weight.

[0029] As attached Figure 4 As shown, the vertical keel is similar to a spring structure, which helps to reduce the impact and vibration of the sound insulation panel and improve its service life.
