An interlayer sound-absorbing apparatus of a building structure and an installing method thereof are provided to transfer the noise caused by the upper side to the panel, to absorb the noise through the vibration prevention panel, and to completely block the noise by keeping a predetermined gap between panels through the vibration prevention pad. An interlayer sound-absorbing apparatus of a building structure comprises square-shaped panels(100,100a) closely contacted to form a floor structure; plural grooves formed at the lower surface of each panel to be downwardly opened; and a vibration prevention pad(200) of a resin material fitted in the groove to allow the panels to keep a predetermined gap from the floor surface. A mounting protrusion(120) is formed with a pin hole(122) at both sides of one edge of the panel and extended like a step. Plural grooves are formed at the lower surface of the panel to be downwardly opened and to reduce weight. |
