The application provides a vibration isolation tie-in box for a floating floor and a floating floor, and belongs to the field of fabricated buildings. The floating floor comprises a bottom layer, a sound insulation layer and a surface layer. The sound insulation layer is laid on the bottom layer, and the surface layer is cast in place on the sound insulation layer. The vibration isolation tie-in box comprises a main body, a vibration absorption layer and a tie-in member. The main body has a closed damping chamber inside, and the vibration absorption layer is attached to the main body. The main body is embedded in the bottom layer, and one end of the tie-in member is installed in the main body in a fabricated manner and extends into the closed damping chamber, and the other end penetrates the sound insulation layer and is tied in the surface layer. The tie-in member and the main body of the vibration isolation tie-in box constrain the surface layer on the bottom plate, preventing the surface layer from cracking due to uneven local compression deformation of the material of the sound insulation layer. The vibration at the end of the tie-in member is blocked in the closed damping cavity of the main body, and the sound bridge between the main body is blocked by the vibration absorption layer, thereby simultaneously solving the cracking and sound insulation problems.

This invention provides a floor slab, including a foundation floor slab, a floating floor slab, and at least one vibration isolation mechanism. The vibration isolation mechanism is disposed between the foundation floor slab and the floating floor slab, and includes a primary displacement amplification mechanism and a secondary hydraulic vibration damping mechanism. The input end of the primary displacement amplification mechanism is connected to the bottom end of the floating floor slab, and the output end of the primary displacement amplification mechanism is connected to the power input end of the secondary hydraulic vibration damping mechanism. The primary displacement amplification mechanism is also connected to the top end of the foundation floor slab. The primary displacement amplification mechanism is used to convert and amplify the vertical displacement of the floating floor slab into a horizontal displacement and transmit it to the secondary hydraulic vibration damping mechanism. The secondary hydraulic vibration damping mechanism forms hydraulic impedance through hydraulic differential amplification to reduce the low-amplitude, low-frequency vibration of the floating floor slab.
