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 axisymmetrically and coaxially an elastic core is placed, along the axis of which cavities are rigidly fixed along the entire length, damping discs along the axis of the cylinder are rigidly fixed along the entire length of the cylinder cavity, while the extreme discs are fixed "flush" with the cylinder of the vibration damping material, whose ends, in turn, are located "flush" with the side surfaces of the base slab, and the intermediate damping discs are located uniformly with a pitch not exceeding the internal diameter of the cylinder, while damping discs fixed rigidly along the entire length of the elastic core of the vibration damping insert are made combined and consisting of an elastic part in the form of discs of rigid vibration damping material oppositely fixed on the elastic core and a damping part made in the form of a disc made of a vibration damping material, for example polyurethane.
EFFECT: increase in the vibration-absorbing and sound-insulating properties of the floor.
