Description

Interlayer noise prevention mat that can be disassembled and assembled for each unit mat}

The present invention relates to an anti-noise mat, and more particularly, it is installed on the floor of an apartment or house and is decomposed into unit mats so that noise transmitted to the lower floors can be shielded by buffering and absorbing vibrations and shocks generated in the upper floors. It relates to a mat for preventing noise between floors that can be assembled.

In addition, in the present invention, a configuration is added to prevent foreign matter or liquid from flowing through the connection part of the mat to contaminate the floor or prevent mold from occurring on the floor, thereby eliminating the problem of reconstructing the floor in advance, resulting in property damage. It relates to a mat for preventing inter-floor noise that can be disassembled and assembled for each unit mat to prevent and reduce noise.

In multi-story buildings such as apartments and villas, which are modern residential types, impact noises and vibrations generated during the lives of upper-floor residents are transmitted to the lower floors intact, which can cause disputes between residents of upper and lower floors.

For this reason, in families with infants or children, by laying a certain size anti-noise mat in the living room, etc., when the child runs or plays, the impact sound and vibration transmitted to the lower floors are prevented to some extent and at the same time, the child does not get hurt when he or she falls. making sure not to

The anti-noise mat refers to a mat for reducing vibration noise caused by noise and impact generated in an interfloor or adjacent space.

In order to improve the anti-noise function, these existing anti-noise mats increase in thickness and volume, or in terms of function, the effect of reducing vibration noise due to noise and impact does not meet expectations, so there is a possibility of disputes between residents of upper and lower floors. will remain

In addition, most of the conventional anti-noise mats are composed of a single layer of foamed synthetic resin or by laminating a finishing layer on the surface of the foamed synthetic resin layer, which has a problem in that the effect of blocking noise and vibration does not meet expectations.

Therefore, considering the reality that social problems due to noise in residential spaces frequently occur, there is an urgent need to develop a new concept of noise prevention system that can solve noise problems without modifying existing building structures and facilities.

In addition, the conventional mat has a structure in which ventilation is difficult as a flat bottom surface is adhered to the floor surface of a living room or the like, and it is difficult to separate the mat and ventilate when foreign substances or liquids permeate into the connection part of the mat. As a result, after a certain period of time, mold or discoloration occurs on the bottom and bottom surfaces of the mat, resulting in high costs for re-construction, causing property damage and causing the mat to separate from the floor and flow. there is
