The principle and the advantages of the scheme are as follows: in the scheme, the damping cushion blocks are fixed on the original structural floor slab, the connecting blocks are filled between the damping cushion blocks, and the steel plates are paved on the damping cushion blocks and concrete is cast on the construction floor. The vibration source is completely isolated from the floor slab with the lower structure, and the transmission of vibration in the vertical direction is avoided, so that the effect of preventing the propagation of vibration and noise is effectively achieved.
Preferably, as an improvement, the damping cushion blocks are regularly distributed on the floor slab in a rectangular array arrangement mode.
So set up, the range of damping cushion neat orderly, the rule that the space that leaves between the damping cushion is more, be convenient for like this more with the neat tiling of connecting block between the damping cushion, and can make and lean on between connecting block and the damping cushion compacter, the gap between connecting block and the damping cushion is little, the effect that gives sound insulation is better.
Preferably, as an improvement, the connecting block is rock wool.
The connecting block adopts the rock wool in this scheme, not only makes the space between the rock wool can fill the damping cushion like this, still has heat retaining effect simultaneously.
Preferably, as a modification, the coupling portions of the vertical members of the floor slab are each provided with a frame spacer.
In this embodiment, the frame isolation bars are disposed at the connection portions of the disposal members of the floor slab, for example, the corners or the column feet around the floor slab region, so that the integrally poured concrete layer can be completely isolated from the wall surface, and the transmission of the vibration source in the horizontal direction is avoided.
Preferably, as a modification, the number of the steel plates is multiple, and the steel plates are fixedly connected with each other.
So set up, adopt a plurality of steel sheets flatly to spread on connecting block and damping cushion, more convenient operation, and more make things convenient for workman's transportation and removal.
Preferably, as an improvement, the upper surface of the steel plate is provided with a protective layer.
So set up, clearing hole, seam seepage form the acoustic bridge on the structural floor slab when the protective layer in this scheme can prevent to pour when mixing earth.
Preferably, as an improvement, the steel plate is provided with a layer of reinforcing mesh.
The arrangement of the reinforcing mesh can enhance the structural strength of the poured floor slab.
Preferably, as an improvement, the damping cushion block is a rubber damping cushion block.
So set up for the damping cushion has elasticity, can play the effect of buffering, can effectively avoid the structural noise because of striking noise arouses.
