FIELD: construction.
SUBSTANCE: invention relates to construction and may be used for vibration isolation, sound insulation in enclosed spaces when installing and installing ventilation units, compressors, generators and other equipment. This is achieved by the fact that in the vibration damping insert for the cavities of the inter-floor slabs, made in the form of a cylinder of rigid vibration damping material inside which an elastic core with disks is axisymmetrically and coaxially located, damping discs are rigidly fixed along the entire length of the cylinder cavity along the axis of the elastic core, while the outer discs are fixed flush with the cylinder made of vibration damping material, the ends of which, in turn, are flush with the side surfaces of the base inter-floor slab, and the intermediate damping discs are located uniformly with a pitch not exceeding the internal diameter of the cylinder, while the damping cavities in the vibration damping insert formed by the damping discs are filled with a vibration damping material, e.g. cast polyurethane, and the cavities formed by the extreme damping discs and adjacent discs are filled with chips from vibration damping material, e.g. "Agat" type, or damping cavities in the vibration damping insert, filled respectively with polyurethane and chips from vibration damping material, are sequentially arranged along the length of the cylinder.
EFFECT: increase in the vibration-absorbing and sound-insulating properties of the floor.
