The contact area 201 is minimized and the contact area is minimized, so that the impact sound caused by the noise of the vibration is reduced and heat loss can be minimized, but the projected sound insulation portion 11 'and the projected sound insulation portion

By using only the space portion 30 'generated between 11', the primary prevention of the phenomenon that noise is transmitted to the lower side did not bring a satisfactory noise prevention effect;

In particular, the mat-shaped member 20 'is pushed to the inner surface of the substrate 10' by the weight transmitted from the upper part of the finishing mortar, etc., thereby lowering the noise preventing effect and absorbing the shock sound by vibration. There was a problem such as not being able to do it;

Due to the formation of a plurality of protruding sound insulation portions 11 'and a laminated portion 13', the building floor surface

When buried after installation on the concrete slab layer 201 or the foam concrete layer 202, which is 200, the work was difficult, and there was a problem such as a cost increase.

Therefore, there is an urgent need for sound insulation materials having a structure that can prevent more effective noise transmission.

The present invention solves the problems of the prior art described above, improves the structure of the soundproofing material for noise prevention, minimizes the transmission of light noise such as light and heavy noise such as vibration to the bottom, can bring excellent sound insulation effect In addition, it is an object of the present invention and the technical object of the present invention to provide a sound-proofing material for noise prevention of the configuration that can bring about improved insulation and workability.
