Description

A panel for interlayer sound insulation and manufacturing method and construction method thereof

The present invention relates to a single panel for sound insulation between floors, a method of manufacturing the same, and a construction method applying the same, and a single panel for sound insulation between floors to reduce the impact noise transmitted by placing between the floors of a multi-family building such as an apartment house, and its manufacture It relates to the method and the construction method applying it

In general, apartment houses, such as apartments, multi-family houses, and multi-family houses, are buildings built so that different multi-family units are built to one another, and noise generated between the furniture is transmitted through the floors to generate inter-floor noise.

That is, in an apartment house, when a shock sound that vibrates the floor, such as when people walk or objects fall from the upper floor, is transmitted to the lower floor through the ceiling or wall. The concrete slabs that form the floors of the apartment house can play the primary sound insulation function between the upper and lower floors, but only a part of the floor impact sound is attenuated and transmitted to other adjacent households or lower floors, causing inconvenience. The inter-floor noise has been continuously causing problems as apartment houses such as apartments increase.

As described above, as inter-floor noise problems continue to occur, inter-floor sound insulation panels interposed on concrete slabs during construction of apartment houses have been developed to reduce inter-floor noise. The interlayer sound insulation panel is formed of styrofoam having a certain thickness and is installed between the layers, thereby absorbing the impact sound generated from the upper layer.

In the case of lightweight impact sound, it can be easily attenuated using a conventional interlayer sound insulation panel, but there is a limit to attenuating the interlayer noise of the weight impact sound. That is, the conventional interlayer sound insulation panel has a problem that when a weight impact sound occurs, the sound insulation effect is not exhibited and the interlayer noise is transmitted as it is.
