The present invention relates to a floor-to-slab slab noise prevention structure for dustproof / absorbing indirect resonance noise as well as a direct transmission route of vibration and shock noise transmitted to the slab.

Structures for blocking vibration and noise between floors in buildings such as apartments are known a lot.

In the accompanying drawings, Patent No. 10-0552981 shown in FIG. 1A includes an upper plate portion, a support portion supporting the upper plate portion, a filling means filled between the support portions, and a noise preventing means provided on the lower surface of the support portion. The legs supporting the support are long and short.

The problem in that the noise preventing means has been devised has a problem that the vibration / shock noise is transmitted to the lower slab as it is through the support structure through the noise prevention means for supporting the heating pipe and the support structure.

In addition, among the accompanying drawings, the method and apparatus for preventing noise between floors of apartment houses, such as apartments of Patent Publication No. 10-2006-0003302 of FIG. 1B, are intended for sound insulation through spaces by constructing a floor structure ondol layer on a slab. The support 30 is installed only around the floor, that is, in the vicinity of the wall 20, and a pure space is formed at the center of the ondol layer to prevent shock / noise. Although there is a tube, the impact of the upper layer through the support is reduced, but there is a residual impact / noise, and the floating floor is closed and acts as a ringer, so that the space on the impact on the heating pipe layer rings, the vibration noise sounds in the lower slab. There was this.

In addition, there are many patents that take measures to prevent noise between floors of slabs. However, in order to prevent / block the noise of the upper floors, the sound absorbing or floating floor structure is formed by buffering the support to give sound insulation effect.

In particular, the floor-type noise-proof structure with a space on the slab floor is sealed, so the impact noise does not go out of the space. It was difficult to achieve the effect.

Therefore, in order to prevent the inter-floor noise through the floated floor structure, the contact structure with the slab is removed from the conventional structure, so that the primary vibration is prevented and absorbed, and at the same time, the floor space with shock noise is prevented from causing repeated howling. Noise can be reflected out to reduce resonance on the floated floor, so that vibration and shock noises are secondarily prevented. In particular, vibration and shock noises reflected to the interior are dissipated to the outside through the ventilation holes provided on the ceiling. It needs to be done.

The slab interlayer noise prevention structure that reinforces the sound-absorbing material laminated on the heating pipe layer and at the same time eliminates the shock and vibration noise of the 1,2,3 order.

The present invention reinforces / forms the sound-absorbing and waterproof layer combining the soundproofing net of honeycomb structure and the waterproof sheet so as to make possible the sound absorption of the floor impact sound transmitted from the heating pipe layer primarily by supplementing the disadvantages of the conventional interlayer noise preventing structures. It is supported to be absorbed through lattice of wood in the lower layer, and it is made of dustproof rubber built into the C channel at the bottom to be in contact with the slab, so that the primary vibration of direct vibration and impact noise is made and at the same time through the floating floor space. It cushions the sound as a reflection of noise and spreads it to the room through the ventilation holes on both sides to prevent resonance noise of the floor structure that has been floated before, and sends vibrations and shock noises that have spread into the room from the ceiling to the outside or predetermined Providing a comprehensive slab interlayer noise prevention structure for sound absorption through sound absorption ventilation pipe There is an ultimate purpose in having.
