FIELD: construction.
SUBSTANCE: vibration cushioning insert for cavitied of interfloor overlapping plates is made in the form of a cylinder of rigid vibration cushioning material inside which elastic core is located axisymmetrically and coaxially, along the axis of which damping disks are rigidly fixed along the entire length of the cavity. The end discs are fixed flush with a cylinder of vibration cushioning material, the ends of which are located flush with side surfaces of the base plate. Intermediate damping disks are located evenly with a step not exceeding the internal diameter of the cylinder. Damping disks fixed rigidly along the entire length of the elastic core of vibration cushioning insert, are made combined and consisting of an elastic part in form of disks of rigid vibration cushioning materia loppositely mounted on the elastic core, and a damping part made in the form of a disk of a vibration cushioning material, for example polyurethane.
EFFECT: invention makes it possible to increase vibration-cushioning and sound-insulating properties of the floor.
