FIELD: mechanical engineering. ^ SUBSTANCE: unit is designed for protection of building structures and equipment of extra precise production from vibration effect and can be implemented for connecting roof of buildings with exhaust, ventilation and other ducts subject to vibration effect. The unit consists of a protecting apron secured on the duct, of a transitive upturn with anchor bolts arranged on it, and of a fit ring put on anchor bolts. The fit ring is made detachable in plane perpendicular to its axis, it is equipped with an upper and lower crimp seals made along its internal diametre and equipped with a spherical elastic anti-friction insertion secured on the internal surface of the fit ring from the side of the duct. The duct is equipped with a ball segment forming a pivot with the anti-friction insertion; the fit ring is put on the anchor bolts of the transitive upturn with a vibration damping padding. The crimp seals of the ring are equipped with vibration damping circular bushings with vibration damping fingers. ^ EFFECT: increased service life of roof. ^ 2 dwg |
