FIELD: protection 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. This structure comprises reinforced concrete 6,000×1,800 mm panels, at that, the non-destructible part is made in the form of bearing ribs arranged along the destructible part outline, and the collapsible part is made in form of, at least, two coaxially arranged recesses in building wall, one of which, the outer one, is formed by the planes of regular quadrilateral truncated pyramid with rectangular base, and the other – internal, is two inclined surfaces connected by an edge, with formation of a groove, thus the thickness of a wall from a rib to an external surface of a fencing of a building should be not less than δ=20 mm, when exposed to impact, explosive load, this section of the wall can be divided into separate parts, and opposite the collapsing part, from the outside of the building fence, is a protective screen made of high-strength material, for example, armor-piercing 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, and the disks located from the right side of rods are immured into the building cladding, and the discs from the left side of the rods are rested by elastic elements underpinning the protective screen to the buildings cladding.
EFFECT: higher reliability of collapsible explosion-proof devices during emergency explosion at site.
