Description

{Construction structures and methods for reducing interlayer noise}

The present invention relates to a technique for preventing noise between the upper and lower floors of a multi-family house. More particularly, the present invention relates to a technique for preventing noise from being transmitted to a lower floor by constituting an unsteadily distributed gravel or sand on a floor slab, So that the interlayer noise can be effectively suppressed and prevented.

In recent years, most of the housing types have been converted from single-family homes to high-rise apartment buildings. In order to reduce the weight of the buildings, the floor slab is used as a lightweight material or the floor thickness is thinned. Noise problems are very serious.

Therefore, recently, when the children are running upstairs in a typical apartment, the sound level heard from the lower floor differs from person to person, but it is about 60db, which is the level of talking with each other immediately. .

Generally, thick walls and floors provide good sound insulation. However, since noise and noise caused by shocks and vibrations can not be properly performed, it is necessary to separate the floor surface of the room It must be constructed.

In the floor construction of the apartment house, a separate floor noise barrier is laid on the floor slab, which is the boundary between the upper and lower floors, and air foam concrete is placed on the upper part of the upper floor noise barrier. The bottom mortar layer is placed on the top of the finished mortar layer.

However, until now, the interlayer noise barrier material has been improved in which the effect of noise cancellation is degraded because most weight sound (children's running noise, barefoot sound in the room, etc.) can not be suppressed properly. The patent literature of the prior art developed up to now is as follows.
