COUNTER-EXPLOSION PANEL OF KOCHETOV Russian patent published in 2017 - IPC E04B1/92 

FIELD: fire safety.

SUBSTANCE: counter-explosion panel with a combined damping element, containing a metal armored frame with a metal armored shell and a lead filler, which has four fixed support sleeves in the ends, and four support rods rigidly embedded in the cover of the explosive object, which are telescopically inserted into the stationary support sleeves of panels, the filler is made in the form of an air-lead disperse system. The lead is made in the shape of a crumb, and on the outside of the support rods there are resilient damping elements, one end of which rests against the armored metal skin, and the other end is placed in the abutment sheets located in the upper part of the support rods, the elastic-damping elements are in the form of cylindrical helical springs, The helical surface of which is covered with vibro-damping mastic, for example of the type VD-17. The filler is made in the form of a ball-shaped crumb of the same diameter, or the filler is shaped in the form of a ball-shaped or randomly shaped crumb of different diameters. To fix the limit position of the panel to the ends of the supporting elastic rods with stop sheets, a damping element is attached, designed to dampen the impact loads of the panel against the stop sheets. It is attached oppositely to the panel and is directed towards it, and is made in the form of a three-dimensional body with an internal cavity and surfaces that are equidistant to the surfaces of the panel. Its internal cavity is filled with a three-layered symmetric disperse system. The central layer, which is a layer of symmetry of a volumetric body with an internal cavity, and surfaces that are equidistant to the surfaces of the panel, is made of a vibration damping material, and adjacent layers are filled with an air-lead disperse system.

EFFECT: increasing the explosion protective devices operation reliability in case of emergency explosion at the facility, and providing of these structures return into the original position after the explosion.
