Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation walls, in particular to a double-cavity high-sound insulation keel partition wall. Background Art

[0002] With the development of modern architecture and the application of new building materials, the non-load-bearing partition walls of buildings have gradually evolved from traditional masonry solid clay bricks to various lightweight panels or blocks. The traditional light steel keel partition wall is a non-load-bearing partition wall system with a light steel keel as the skeleton and gypsum board as the surface layer, which is hollow in the middle and flat on both sides. When the light steel keel partition wall is used as a partition wall to separate the space, its sound insulation effect is particularly important, and the main medium for sound transmission is air. Therefore, the air tightness of the partition wall structure directly determines the quality of the sound insulation effect. Among the existing light steel keel partition walls, the air tightness of the structural positions such as the opening position, the top installation position, and the bottom installation position is very poor.

[0003] Traditional keel partition walls usually use C-shaped keels in the middle. This type of keel has a thin wall, no support in the middle, poor sound insulation, and a small overall bearing capacity. The conventional solution is to use double-row keel partition walls, but this method will lead to new problems such as extended installation period and installation cost. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a double-cavity high-sound insulation keel partition wall which can effectively provide higher sound insulation strength.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a double-cavity high sound insulation keel partition wall, including a vertical keel arranged in the middle, the upper and lower ends of the vertical keel are fixed to the floor slab by expansion bolts, the inner side of the vertical keel is provided with a sound insulation board, the two sides of the vertical keel are provided with a wall layer, and a sound insulation cavity is provided between the wall layer, a sound insulation layer is provided in the sound insulation cavity, the sound insulation layer is provided with a threading hole, and the wall layer is fixed to the sound insulation layer by self-tapping screws.

[0006] In the above technical solution, the wall layer includes a wall panel and a base plate connected by structural adhesive.

[0007] In the above technical solution, the self-tapping screws pass through the base plate and are fixed on the sound insulation layer.

[0008] In the above technical solution, C-shaped keels and hanging plates are respectively provided on the outer side surface of the base plate and the inner side surface of the wall plate, and are fixed by the C-shaped keels and hanging plates.

[0009] In the above technical solution, the sound insulation layer is rock wool and / or glass wool.

[0010] In the above technical solution, a shock-absorbing sealing strip is provided between the vertical keel and the floor slab, and the thickness of the shock-absorbing sealing strip is 2 to 3 mm.

[0011] In the above technical solution, a skirting line is provided at the connection between the outer side of the wall layer and the floor slab.

[0012] To sum up, the technical solution of the utility model has the following beneficial effects compared with traditional technical means: the utility model improves the shape of the vertical keel, changes the conventional C-shaped keel to a W-shaped keel, and places a sound insulation board in the middle to increase the supporting force of the middle part and enhance the sound insulation and thermal insulation effects. The wall load capacity is increased, and it can be used in combination with assembled keels, which has better applicability. BRIEF DESCRIPTION OF THE DRAWINGS
