FIELD: construction.
SUBSTANCE: invention relates to construction and can be used in vibration control, sound insulation in enclosed spaces during installation and installation of ventilation units, compressors, generators, and other mechanical equipment. Vibration damping insert for building structures is made in the form of a cylinder of rigid vibration damping material, inside which is axisymmetrically and coaxially placed an elastic core with disks. Along the rod axis the damping disks are rigidly fixed along the whole length of the cavity. Herewith the extreme discs are fixed "aflush" with the cylinder from a vibrodamping material, the ends of which, in turn, are placed "aflush" with side surfaces of the base plate. There are intermediate damping disks placed evenly with the step not exceeding the internal diameter of the cylinder. Elastic core, axially symmetric and coaxially placed inside the cylinder of the vibration damper insert, is made of a combined and consisting of an elastic part in the form of a rod and a damping part made in the form of an outer coaxial shell made of a vibration damping material, for example polyurethane. Damping disks fixed rigidly along the entire length of the elastic core are made of combined and consisting of an elastic part in the form of oppositely fixed disks on the elastic core of a solid vibro-damping material, for example an “Agat”, “Antivibrite”, “Schwim”, made in the form of a disk perforated frame of an elastic material filled with a mesh damping element located between the disks of a solid vibration damping material, and made in the form of a disc of a soft vibration damping material, for example, spongy rubber, nonwoven vibrodempirating material, polyurethane.
EFFECT: invention allows to improve vibration-absorbing and soundproofing properties of floor.
