How to construct soundproof ceiling?
1, ceiling preparation
Keels are ready, including suspenders, side keels, load-bearing keels, covering keels, cross-bracing keels, etc. , and ensure the keel installation quality is reliable and qualified. The edge of the keel or joist must be properly cleaned and dried. Remove nails, screws or other obstacles protruding from the keel or joist.
2, ceiling line drawing, indicate the keel.
Measure the workspace, draw a line on the ceiling with an infrared measuring instrument, indicate the position of the shock absorber and keel of the ceiling, and adjust the levelness of the ceiling. Before installing the sound insulation board, the ceiling shock absorber should be installed on the existing ceiling, which can not only reduce the rigid connection between the sound insulation ceiling and the original ceiling.
3. Install the ceiling shock absorber, keel and accessories.
According to the painting position of the ceiling, install the ceiling shock absorber and screws, and the length of the screws is determined according to the height of the ceiling. At the same time, install ceiling pendants and fasteners, fix ceiling keel, and adjust ceiling elevation.
4, measurement and cutting
Measure the workspace, and if necessary, cut the sound insulation boards into appropriate sizes to minimize the gap between the sound insulation boards or between the sound insulation boards and other existing surfaces.
The sound insulation board can be cut from either side by cutting or sawing. When cutting with a knife, first use a standard tool knife or similar tool to carve a deep scratch on one side of the wallboard, and then carve a scratch aligned with the above scratch on the other side, so that the sound insulation board can be broken. In order to keep the seam neat, compact and parallel, we suggest cutting with a chainsaw, and the trimming and both ends should be smooth.
The long side of the installation sound insulation board should be perpendicular to the direction of the auxiliary keel, and the short side should be staggered.
5, sealing, fixing and filling cotton
Use a caulking gun to continuously apply sound insulation sealant with a width of about 5 mm to the existing wall, floor or floor where the outer edge of the sound insulation board will be placed. Place the sound insulation board, after fixing it, apply sealant around it, and repeat the plugging steps to spread the sound insulation board all over the wall. When placing sound insulation boards, try to ensure close contact between sound insulation boards and between sound insulation boards and walls, floors and ceilings. When installing the sound insulation board, put sound-absorbing cotton on the board.
When fixing the sound insulation board, use wallboard screws whose diameter and length conform to local building codes, usually No.8 horn-head fine-tooth screws (used for metal keels). These screws should be screwed to a level position with the surface of the sound insulation board, and there should be no cracks on the surface of the sound insulation board. It should be noted that the sound insulation board is fixed on the keel, with the screw spacing around 100mm and the middle150 mm. The sound insulation board should be attached to the edge of the keel or joist, and the joints of the sound insulation board should be staggered.
6. Sealing of hollow frame and through hole
Because the sound with air and buildings as the transmission carrier has strong permeability, when cutting frames or holes on the wallboard to take care of ceiling lamp holes, pipes, ceiling fans, etc. The gap between the soundproof wallboard and the hollow frame or through hole is sealed with soundproof sealant.
7, joint treatment and decoration
When installing ordinary gypsum board, adhesive tape can be attached to the joints. The surface of the sound insulation board is coated with putty, paint, coating and wall coating.
How to make a soundproof ceiling? For family decoration, we must know more about every link, so that when decorating the family soundproof ceiling, the decoration effect can be more in place and the soundproof effect can be achieved. Therefore, for many families, it is necessary to know more about how to choose the soundproof ceiling, and then follow the process and operate the soundproof ceiling according to the standard to achieve better soundproof effect.
