The present invention relates to a floor vibration and noise prevention device, and more particularly, to a vibration and noise caused by the impact applied between floors of a multi-family house, and to a floor vibration and noise prevention device that can be height-adjusted according to construction conditions. will be.

In Korea, due to the unique heating structure of ondol, when building the floor of a multi-family house, light weight foam concrete with a specific gravity of about 0.5 is placed on the upper part of the concrete slab to secure the horizontal level for the heating coil and the insulation layer at the bottom of the heating coil. It is common to complete the floor structure by installing heating coils on the top of lightweight concrete and placing finishing mortars with a thickness of about 40 ~ 60m.

However, according to the conventional floor structure of the multi-family house, concrete slab, lightweight foam concrete, finishing mortar, etc. are all hard solids, so there is a limit in buffering the impact sound and vibration between the upper and lower layers transmitted from the upper layer to the lower layer. In addition, the problem that the heat transmission rate of 0.7 kcal / ㎡ h ℃ which is the insulation standard of the floor of the multi-family house reinforced with lightweight foamed concrete used as the insulation layer was raised.

That is, according to the conventional interlayer floor structure made of a concrete slab layer, lightweight foam concrete layer, heating pipes and mortar finishing layer, the efficiency of heat insulation and dustproofing against heat and impact sound of a property that is easily transmitted to the same object is reduced.

On the other hand, due to such a problem in the prior art has been proposed a technique for installing a dustproof pad formed with grooves or irregularities on one side or both sides for insulation and dustproof between the concrete slab layer and the lightweight foamed concrete layer, which is the lightweight foam concrete layer There was a problem that the effect of the insulation and dust is greatly reduced by flowing into the grooves or irregularities of the dust pad during pouring, and there was a problem in that the difficulty of construction and cost due to the installation of a separate sealing barrier film is doubled.

In addition, a method of reducing waste floor noise by forming a waste tire chip dustproof layer in addition to the prevention pad has been proposed. However, since the waste tire chip dustproof layer is a non-foaming product, a surface waterproof layer is not formed and thus light weight is placed thereon. As the slurry of foam concrete penetrates into the waste tire chip, the original elasticity is lost, and thus, the desired dust-proofing effect is lowered and the insulation performance is weakened.

In addition, in constructing these dustproof floors, the height of the building can not be adjusted according to the construction state of the multi-family housing, and the foundation of the building may be changed, resulting in excessive cost.

Therefore, the present invention has been proposed to solve the above problems, the height can be adjusted according to the construction state, and provided with an elastic member and a damping member to double the noise and vibration caused by the impact generated between the floors.
