PURPOSE: A support for a floor construction material is provided to maintain a shock-absorbing property of a concrete floor, and secure elasticity and viscosity. CONSTITUTION: A support for a floor construction material(100) comprises a high-hardness composite member(110) and a low-hardness composite member(120). The high-hardness composite member is formed in the top, and has the elasticity. The low-hardness composite member is formed in the bottom, and has excellent viscosity. |
