In this research, we suggest the effective technique that the thickness of slab isn't increased, and considering proper shock absorbing material and supporting point, we make the floating floor which has multi-supporting system floating floor. As the result, it is effective in reduction of heavy weight system as well as one of light weight

The purpose of this study is to investigate a investigating of a floor-impact isolation system using damping materials in apartment buildings. The stiffness elastic modulus(k) by puls impact forces were calculated loss factor by Hilbert transforms. It is absolved that natural frequency was moved floor shock-absorbing materials and the impact force was reduced by floor panel. The slab was constructed by damping materials. As towards a result, the system showed inverse A 45dB by heavy weight-impact noise and inverse A 52dB by light-impact noise. High frequencies impact-noise can be reduced by upgrading naturial frequency of vibration and noise in the system.

This study is concerned with the development of the SL inorganic floor covering. First, volatile organic compounds, inorganic test profile on the SL through the flooring is environment-friendly inorganic noncombustible floor finishes the event of fire toxic gases (such as volatile organic compounds) emissions have been identified as not at all. Second, SL-breathable material, the concrete floor to prevent aging, long life, which are three levels of noise, shock-absorbing function was decreased. Third, SL economic analysis of mineral flooring terrazzo tile floors compared with the normal material. On a terrazzo tile cost 13,500 won ~ 24,500 won, but It have found that, in terms of labor SL 36,899 won ~ 38,899 won flooring mineral balance. Occurs in the total amount when compared with terrazzo tile floors and 25,399 won 3T, 5T and economical analysis concludes that the original 12,399 won.
