FIELD: explosion protection methods.;SUBSTANCE: invention relates to explosion-protection devices used in explosive objects. This is achieved by the fact, that in the explosion-proof destructible structure for the of extremely hazardous industrial facilities protection containing reinforced concrete panels, each of which consists of destructible and non-destructible parts, at that, the non-destructible part is made in the form of bearing ribs arranged along the destructible part outline, and the destructible is made in the form of at least two coaxially arranged recesses in the building wall, one of which, the external, is formed by the planes of regular quadrilateral truncated pyramid with rectangular base, and the other, internal, is two inclined surfaces joined by an edge to form a groove. Opposite collapsible parts, on outer side of building enclosure, protective shield made from high strength material, for example, armored material, which is fixed on, at least, three horizontally located and perpendicular to the building enclosure rods, at which ends discs are fixed, and passing through the holes in the protective screen, wherein the located on the rods right side disks are embedded into the building enclosure, and discs at rods left side rest against resilient elements underpinning the protecting screen to buildings enclosure, at that, the recesses are filled with the heat-absorbing material and covered with the decorative panel, easily destructible during explosion. Protective screen to the of buildings enclosure supporting elastic elements are made in the form of disc-shaped elastic protective package elements for the explosion-proof buildings enclosure destructible part protective screen, each of which contains bearing rod, which one end is rigidly embedded in the reinforced concrete panel by means of the bearing rod base disc, and on the other, free bearing rod end elastic elements package for the protective screen is arranged, bearing rod is rigidly and perpendicularly fixed to the embedded in the reinforced concrete panel base disk. Through the sealing gasket the protective screen is installed on four bearing rods, at that, by one of its ends, guide bushing is rigidly and perpendicularly fastened thereto, coaxial with the bearing rod and enclosing it with the gap, and the guide bushing second end enters with gap in the coaxial with it the disc elastic elements package thrust cover opening, which is fixed to the bearing rod free threaded end by means of the lock washer and nut. Disk elastic elements package consists of in-series connected disc-shaped elastic elements, which central holes inner surface interacts with coaxially aligned to them guide bushing, wherein the each disc-type elastic element comprises disc-type resilient surface in the form of truncated cone, which large bases rest against each other in pairs, forming the fixed on the guide bushing package, at that, between the protective screen and the thrust cover the elastic damping casing is arranged, made, for example, in the form of elastic bellows, coaxially and with gap enclosing the disc-shaped elastic elements package, at that, the bellows rigidity is equal to the disc-shaped elastic elements package rigidity.;EFFECT: increase in the destructible explosion-proof devices operation reliability and efficiency during the emergency explosion at the facility.;5 cl, 2 dwg
