METHOD OF EXPLOSION PROTECTION OF EXPLOSIVE OBJECTS Russian patent published in 2017 - IPC E04B1/92 

FIELD: construction.

SUBSTANCE: method of explosion protection of explosive objects is that in the object covering, symmetrically relative to its axis, at least three supporting rods are rigidly fixed, telescopically inserted into fixed pipes-supports embedded into an explosion protective panel made of armoured steel frame with armoured metal plating and lead as a filler. For locking its end position, sheets-stops are welded to the ends of the supporting rods, and the supporting rods are made hollow with a set of damping disks in the internal cavity.

EFFECT: improved reliability of the operation of explosion-protective devices in case of an unexpected explosion at a facility and providing returning these structures into the original position after the explosion, ensuring the uniformity of dropping excess pressure through an open aperture.
