FIELD: construction.
SUBSTANCE: vibration cushioning insert for hollow elements of building constructions, for example for the construction of a floor on an elastic foundation, is made in the form of a cylinder of rigid vibration cushioning material, inside of which the elastic core is symmetrically and coaxially located. Along the axis of the core, dampening 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 in turn flush with the side surfaces of the base plate. The cavities between the discs are filled with a vibration cushioning material.
EFFECT: improved vibration-absorbing and soundproofing properties of the floor.
