Description

Technical Field

[0001] The utility model relates to auxiliary facilities for energy-saving transformation of buildings, in particular to a high sound insulation partition wall system. Background Art

[0002] Partition walls are walls that separate the interior spaces of a building. The basic requirements for partition walls are that they should be small in weight to reduce the load on the floor and slab; thin in thickness to increase the usable area of ​​the building; and soundproof, water-resistant, fire-resistant, etc. according to specific environmental requirements. Considering that the division of rooms changes with the use requirements, partition walls should be as easy to disassemble and assemble as possible.

[0003] Some existing sound insulation partition wall systems use a central layer and a sound insulation layer. The central layer is made of a composite of lightweight materials and concrete, which is lighter and stronger, thereby meeting the sound insulation, lightweight, high temperature resistance and earthquake resistance requirements of the assembled partition wall, and is used in combination with the sound insulation layer to meet the high sound insulation requirements. However, the central layer of the existing sound insulation partition wall system is usually formed by sequentially splicing multiple small lightweight partitions to form a large partition structure, and the concave-convex matching at the joints of adjacent small lightweight partitions is spliced ​​with each other. When the wall shakes due to an earthquake, the concave-convex matching structure at the joint is easily broken and damaged, causing the wall to be dislocated. In addition, the sound insulation layer of the existing sound insulation partition wall system is composed of multiple vertical purlins arranged at intervals and rock wool boards between adjacent vertical purlins. The sound insulation layer is only pressed and fixed to the central layer by the top and bottom pressure strips. The connection between the central layer and the sound insulation layer is not firm, and earthquakes can easily cause the sound insulation layer to separate from the central layer.
