FIELD: safety devices.
SUBSTANCE: invention relates to safety devices used in explosive and radioactive facilities, such as easy detachable panels and roof, blast guards and shields, excessive pressure valves. Device for protection of an industrial building, in which are made explosion-proof elements: for side enclosures - as a precautionary crumbling enclosing structures of buildings and for top enclosures - in form of explosion-proof plate on roof or attic floors of building, with explosion-proof plate consists of an armored metal frame with an armored metal shell and filler - lead, wherein it is fixed at ends of four fixed support-pipes. Building enclosure is rigidly embedded with four support rods, which are telescopically inserted in fixed plate connections, supports, for fixing limit plate position ends of support rods welded sheet-stops and on side facing metal frame with an armored metal shell, attached additional elements damping effect of shock wave, which are made of elastomer. Safety collapsible enclosure consists of destructible and non-destructible parts, latter is composed of at least two coaxial recesses, one of which, external, is formed by planes of right quadrangular truncated pyramid with rectangular base, and other - internal represents two inclined surfaces connected rib to make slot wall thickness from outer surface of the building cladding shall not be less than δ=20 mm. To load-carrying ribs arranged along outline of purposefully destructible structure are attached at least three horizontal rods, on which shielded screen, which is fixed on rods by locking elements. Armoured screen is fixed to bearing ribs through sealing gasket pressed by springs, one end of which are borne against locking element, and other - in armored screen.
EFFECT: increased reliability of operation of personnel in highly explosive premises.
