How to construct calcium silicate board partition wall can achieve better sound insulation effect

Nowadays, some workplaces are inseparable from the partition wall decoration of calcium silicate board this environmentally friendly plate, because it is sensitive and convenient to install, has become the first choice for building partition walls, calcium silicate board itself has the function of sound insulation, although compared with professional soundproof glass, it is slightly lacking, but if in the decoration of the partition wall, The interlayer of the calcium silicate board is filled with a substance called sound-absorbing cotton, which can fully achieve professional sound insulation.

First, the construction of calcium silicate board partition wall adding sound absorbing cotton

The selection of materials and materials used in different places are not the same, and the thickness of calcium silicate board used in the decoration of the partition wall of the studio is usually 8mm standard. Calcium silicate board partition wall are supported by light steel keel, the theme of the keel to establish the end, the main frame of the interval can be established according to their own needs, can also be placed according to the thickness of the plate, in the keel wall construction also need to use is the self-tapping screws, self-tapping screws are used to fix calcium silicate, the density of its use is about 10cm. It can not be lower than this interval, if it is lower than this interval, the fixed plate may appear unstable or appear cracked in the future.

First fix one side of the board, and fill in the sound-absorbing cotton, the amount of cotton depends on what kind of sound insulation effect needs to be achieved. Finally, the second side of the calcium silicate board is fixed with self-tapping screws, so that the basic construction of the partition wall is completed. The wall of the calcium silicate board partition wall can also be decorated with inorganic pre-coated board, if you need to decorate KTV, the thickness of the calcium silicate board used is at least 10mm or more, in order to achieve the expected better sound insulation effect.

Second, the construction of conventional calcium silicate board partition wall

1. Order of wall panel installation: Wall placement → rectification of the pipe in the partition wall → wall pad construction → equipment along the ground and along the top keel → equipment vertical keel → Fixed door and window openings → Equipment partition wall → surface calcium silicate board → fill with insulation material or sound absorbing cotton (only in When it comes to sound insulation wall and insulation wall) → drill the water heating pipeline hole and lower the pipeline → inspect various pipelines in the wall → calcium silicate board on the other side of the equipment partition wall → joint disposal → wall decoration → equipment toe line.

2. When double-layer calcium silicate board partition wall equipment is used, the fixing method of a layer board is the same as that of a single-layer calcium silicate board wall; The tension seam of the second layer of calcium silicate plate cannot fall on the same vertical keel with the first layer of seam (including the longitudinal seam of the column).

3, calcium silicate board equipment should be longitudinal paving board, as far as possible to reduce the horizontal joint; The edge of the plate should fall in the middle of the keel (keel spacing should be closely matched with the plate width); When the wall is higher than the height of the board, the horizontal keel should be added to the longitudinal joint of the board.

4, the ceramic tile calcium silicate board partition wall, the equipment method of the board is the same as that of the single-layer calcium silicate board wall, but the equipment is necessary to the smooth surface of the board towards the keel, the hair surface faces out, so that the mortar can communicate with the board. Apply 6mm thick 1:1 cement mortar and 107 adhesive bonding layer on the hairy surface calcium silicate board, and then bond 5mm thick ceramic tiles on the bonding layer.

5, the board and keel are fixed with 4mm×25mm self-tapping screws, the middle barrier of the screws around the board is less than 200mm, and the middle barrier of the screws in the middle of the board is less than 300mm.

6, because the panel and the main keel overlap width is small (about 20mm), so the keel spacing specification is necessary to be accurate, and adhere to vertical.

7, the board seam with putty caulking, then towel joint paper tape, scraping putty, grinding flat; The ratio of calcium silicate board caulking putty is: old powder 6, gypsum 1, 107 glue, water is suitable for work (gypsum powder is added in order to caulking can have micro-expansion); Caulking is usually inserted 2 to 3 times; The seam width is usually 5~7mm.

In modern house decoration, the sound insulation and fire retardant effect of house partition wall decoration are very important. The use of light steel keel with calcium silicate board partition wall can meet these two needs, providing a safe and comfortable living, office, leisure and entertainment environment.
