PURPOSE: A floor supporting apparatus is provided to easily control the installation height of floor on a concrete slab and to secure excellent shock absorbing, dustproof, and soundproof effects of floor. CONSTITUTION: A floor supporting apparatus(100) comprises a lower base part(110), a lower shock absorbing part(120), an upper base part(130), an anti-release piece(140), and an upper shock absorbing part(150). The lower base part comprises a hemi-spherical support(111), a base(112), and a base pipe. The lower shock absorbing part is made of an elastic rubber material and supports the lower base part for absorbing and dispersing an impact applied to a concrete slab. The upper base part comprises a support bracket(133) and a screw shaft(134) which is coupled to a screw hole of the base pipe and allowed to control height. The anti-release piece is coupled to the screw shaft and allowed to move up and down to restrict the height control of the upper base part on the lower base part. The upper shock absorbing part is composed of a support block(151) of an elastomeric rubber material which is detachably installed inside the support bracket of the upper base part and interposed between square members placed on the support bracket in order to absorb and disperse an impact applied to the square members. |
