Description

Technical Field

[0001] The utility model relates to a partition wall system, in particular to a high-sound insulation light steel keel sandwich partition wall system, belonging to the technical field of building decoration. Background Art

[0002] At present, the industry's high-sound insulation light steel keel partition wall system uses sandwich sound insulation panels as the internal structure, which are installed by snapping into the groove in the middle of the light steel keel. The inorganic sound insulation board is fixed on the side of the keel (the two ends of the inorganic sound insulation board are snapped into the groove in the middle of the light steel keel on the corresponding side), and the keel cavity is filled with fireproof sound insulation cotton to improve the sound insulation performance. During implementation, various components, such as light steel keel, sound insulation board, fireproof sound insulation cotton, sound insulation board and other materials are transported to the site in a scattered state for assembly and partition wall installation.

[0003] The partition wall system of the above structural form has the following disadvantages:

[0004] (1) Due to the groove-insertion installation, the sound insulation board needs to be installed at the same time when installing the light steel keel. That is, after installing the light steel keel on one side, the sound insulation board needs to be inserted into the groove first, and then the light steel keel on the other side is installed and the keel groove is inserted into the sound insulation board. The installation process of the two materials overlaps, the process is complicated, and the construction efficiency is slow.

[0005] (2) To ensure that the sound insulation board can be inserted smoothly into the light steel keel, the mounting groove is not in close contact with the sound insulation board (there is a gap between the sound insulation board and the groove). At present, the gap is treated with sealant during on-site construction, which may cause harmful gas volatilization and construction quality problems.

[0006] (3) Decorative panels cannot be directly installed on the partition wall keel. It is necessary to use the inorganic board as the reference surface and then make the decorative panel skeleton for the installation of the decorative panel. The installation process of the decorative panel is relatively cumbersome. Utility Model Content

Two through-core keels 4 are horizontally arranged in the middle of the height direction of the partition wall system. The two through-core keels 4 are arranged in a front-to-back interval along the thickness direction of the partition wall system. Fig.11 As shown, the cross section of the through keel 4 is U-shaped, and the U-shaped opening is downward. The through keel 4 penetrates the sound insulation keel 3 through the through keel through hole 32 on the sound insulation keel 3. The through keel 4 connects the vertical sound insulation keels 3 in series to enhance the horizontal load bearing of the entire frame.
