brief introduction
Damping hangers are often used for ceiling suspension. Limit and reduce the noise of the upper floor, ceiling components, block the passage of structural noise, in other applications, suspended ceiling with damping suspension can help to maintain the original sound quality, such as music practice room, studio, etc.
The suspension rack is fully enclosed, with simple structure, high forming strength of the filling die, clear force, low natural vibration frequency, good damping effect, strong attachment and wide application. It is well received by customers.
Selection method
1. Factors that should be considered when choosing:
(1) the total weight of suspended objects is the most.
(2) the frequency of external interference.
(3) size, location and location of supporting points.
(4) Use of environmental conditions (such as temperature, location of installation space, surrounding clearance and tensile, anti-radiation and sound insulation conditions).
2. Selection method
(1) Choosing the step ratio f/fn properly in order to achieve the best damping effect, the natural frequency of elastic support must satisfy the condition of f/fn > 2 in principle. The frequency ratio is larger than that of continuous trench, and the better the damping effect is. The f/fn value is usually between 2.5~5, and the damping effect can reach 80~95%.
(2) Planting load is expected to be used in the optimum load range of the suspension frame. In principle, the maximum load is not exceeded at all. If the load exceeds the optimum load, the vibration absorber is easy to be damaged and far below the rated load. The natural vibration frequency of the system rises and falls, and the frequency ratio is lower than f/fn.
(3) taking into account the dimensions and rigidity of the vibration isolation equipment, the layout of the supporting points should be selected appropriately.
(4) pay attention to the suitability of environmental conditions for the application of vibration damping hangers.
Brief description of isolation suspended ceiling for use and installation of damping hangers?
(one) circumference
Prevent noise and vibration from spreading through ceiling hangers and suspended mid ceilings.
(two) material
1. Damping hanger: The hanger is composed of a steel box with a compression spring installed inside the rubber ring. The diameter of the charge and the size of the lower part of the hanger should allow the hanger rod to pass through and swing.
2. Dense mesh rubber sponge 6 mm thick.
3. Compact glass fiber is 50 millimeter thick.
(three) construction procedures for isolation of smallpox
1, according to the left, right, front and rear center distance 1200 mm, draw the ceiling supporting line.
2. When installing the suspension frame, ensure that the angle of the suspension frame is perpendicular and does not collide with pipes, pipes, roof beams and other arrays.
3. Connecting the suspension line with the lower end of the suspension frame, the method is to install the steel pipe of the top slab roof strip of the first floor 16mm and cover the surface of the upper slab as completely as possible with 50 mm glass fiber tile of the ordinary steel roof barrier structure.
4. When installing the second level 16 mm plasterboard, ensure that all joints are interlaced.
5. Light angle steel is installed around the ceiling, one of its supporting feet is connected with the wall by midge bolt, and the sponge rubber is placed on the top of the horizontal supporting feet to support around.
6, around the gap.
7. When the sound-transmitting tile ceiling is under the sound-limiting ceiling, the lifting line from the sound-transmitting ceiling shall continue to be lowered and all the lifting lines shall be filled with holes throughout the plaster ceiling.
8. Additional hangers should be added to the upright position of the sound insulation ceilings of the structural equipment, pipes or pipes. Because the equipment and sponge sleeve should not be connected to the sound-proof ceiling, and the suspender should be through the sound-proof ceiling, the sponge sleeve throughout the sound-proof ceiling filling gaps.
