SHOCK ABSORBER FOR BLAST PROTECTION ELEMENTS OF BUILDINGS Russian patent published in 2015 - IPC E04B1/92 F16F7/00 

FIELD: construction.

SUBSTANCE: disposable shock absorber comprises a body, elastic and damping elements, additionally comprises a support rod, to which a stop in the form of a plate is stiffly fixed perpendicularly to its axis. To the lower surface of the stop a damping base and a coaxially arranged flanged bushing are fixed by the screws, and the upper flange of the bushing is connected to the damping base, and the lower one - with the pressing element of the bushing type with grooves for fixation of one of the ends of the elastic element, made in the form of a conical spring, the other end of which stops against a sleeve with a bottom and a central hole, in which the rod is coaxially placed. On the outer surface of the flanged bushing there is a safety bushing installed coaxially to the rod, made of brittle disposable material, for example, porcelain, or from a vibration damping material. The sleeve is also made of brittle disposable material, for example, porcelain, and is fixed by its shell to the pressing elements by screws. The flanged bushing arranged coaxially to the support rod, the upper flange of which is connected to the damping base, and the lower one - to the pressing element of the bushing type, is made of a vibration damping material, for instance, polyurethane.

EFFECT: invention makes it possible to increase reliability of actuation of blast protection devices in case of an emergency explosion on a facility.
