VIBRATION AND NOISE REDUCTION MATERIAL FOR BUILDINGS

摘要

The present invention relates to a vibration and noise reduction material between floors for an apartment building and, more specifically, to a vibration and noise reduction material between floors for an apartment building, wherein primally generated vibration energy passes through a structure stacked in a multiple stage for vibration to be uniformly dispersed, and a direction of vibration is rotated for final vibration transmitted to a floor slab to be weaken. Moreover, when vibration in an upper portion is transmitted by changing a material, a frequency is converted for noise to be reduced. As stated above, according to the present invention, a reduction material for an apartment building enables primally generated vibration to be uniformly dispersed in a plastic corrugated layer, and replaces vibration which is uniform in an upper portion of a steel band formed as a thin steel plate to be linear. Moreover, as the replaced vibration is secondarily and uniformly dispersed in an EVA band, final vibration transmitted to a floor slab of the lowest end is efficiently reduced. Further, construction is simple and easy for workability to be improved, and working time is shortened.
