The sound insulation treatment of bars and slow-shaking bars mainly includes ceiling sound insulation treatment, floor sound insulation and vibration reduction treatment, and wall sound insulation treatment. Henan Bofu undertakes bar sound insulation projects and sells bar sound insulation materials.
) The soundproof ceilings of bars and slow-shaking bars adopt elastic ceilings without any rigid connection with the original structure to prevent sound from hitting the original structural floor of the building and then being transmitted to the guest rooms on the upper floor. The designed sound insulation attenuation is B, and the sound resonance frequency Point less than or equal to. The elastic sound insulation ceiling should be as close as possible to the ceiling to ensure indoor static height. The designed length of the boom is, if possible, it can be shorter according to the conditions at the construction site. The length of the local boom (if it encounters beams, ventilation pipes, water supply and drainage pipes, etc.) needs to be adjusted according to the actual height. The lower edge of the finished surface of the elastic ceiling should be located above the fire sprinkler ducts and air conditioning ducts. The suspension of lighting racks, ventilation, air conditioning ducts, and partial decorative prefabricated parts must be isolated from the original floor with shock absorbers. In order to ensure the sound insulation effect, when the cables and fire pipelines in the soundproof ceiling penetrate the soundproof ceiling, they must be sealed with sealant to prevent sound leakage. There is no need to open large holes for lighting fixtures, air conditioning outlets, or destroy the sealing of the soundproof ceiling, which will help increase the insulation volume.
)The ground is designed for sound insulation and vibration reduction, which is separated from the original structure through a vibration-absorbing cushion, effectively blocking sound from hitting the original structural floor of the building and then being transmitted to the entire building structure. The distance between the damping pads must be determined according to the designed sound resonance frequency point and load-bearing capacity. They cannot be placed less or more. During the construction of composite sound insulation board paving, the surface should be flat without leaving any gaps. The gaps should be sealed with dry cement mortar. After drying, cement concrete should be poured over a large area. This can prevent the cement slurry from entering and forming a solid connection. The bucket truck cannot be used during construction. Use it on the composite sound insulation board to prevent it from being crushed. The cement mortar cannot flow into the gaps.
) The sound insulation treatment of the wall adopts the method of light steel keel sound insulation board. The main purpose is to reduce the impact of sound waves on the wall.
