In the interlayer noise prevention panel integrally provided with a plurality of support parts at the bottom of the main body, a plurality of elastic bands that protrude downward and then protrude upward again are arranged in a circular shape, and the ends of the elastic bands protrude downward. A support bar protruding upward from the protrusion is formed, but the support protrusion protrudes from the bottom of the elastic band, and the upper end of the support bar is installed close to the bottom of the upper concrete installed on the upper part, so that the upper end of the support bar is the upper end of the upper concrete when a heavy load occurs. It is a structure in contact with the bottom.

The inter-floor noise prevention panel having such a structure effectively blocks small impact sounds and generates a large impact as the support provided at the bottom has its own elasticity and has a support rod on the upper portion of the support rod when a sagging phenomenon of the upper concrete occurs. As the upper concrete touches the end, it prevents further descent, thereby preventing deformation of the support and also preventing cracks in the upper concrete. In addition, while forming the support part with a plurality of elastic bands, the support protrusion is formed to protrude at the lower part, so that the impact sound is primarily exhausted by the main body and secondary by the support part. It has the effect of minimizing the transmission of impact sound by being exhausted.

However, as the inter-floor noise prevention panel is provided as in the prior art, the construction cost greatly increases, and there are problems in that it is cumbersome to continuously assemble in all directions and takes a long time.

When the mortar (M) is poured, the mortar (M) is introduced into the insertion hole (11) of the insulating material (10), and the vibration-proof rubber (20) is lowered to be more closely attached to the slab floor (S). In this way, as the vibration-proof rubber 20 is in close contact with the slab floor (S), cracks of the cured mortar (M) are prevented, and the impact sound is effectively absorbed.

When an impact sound is generated from the upper floor in a building with an inter-floor noise prevention cushioning material constructed in this way, the impact sound is effectively absorbed by the inter-floor noise prevention cushioning material 100 and the buffering rubber 20, and the first protrusion 14 And there is an effect of preventing the resonance phenomenon in the space between the second protrusion 15 and the air cap (2).
