Fabricated floating damping system

The utility model provides an assembly type floating damping system which is used for solving the technical problems that in existing floating damping building construction, the isolation damping effect is poor, the construction efficiency is low, the construction complexity is high, the construction quality is poor, and an existing building structure is extremely prone to being damaged. The damping device comprises a bottom plate, a first damping mechanism and a second damping mechanism, the first damping mechanism is fixedly installed on the bottom plate, and the second damping mechanism is fixedly installed on the first damping mechanism. The construction process is simplified in the mode that the bottom plate is directly arranged on the floor slab of an existing building to support the whole floating damping system, the existing building does not need to be damaged, the construction effect is good, the construction efficiency is high, the two damping mechanisms are arranged, multiple damping assemblies ar
