FIELD: construction.
SUBSTANCE: invention relates to protection devices used in explosive and radioactive facilities. The rupture structure of cladding comprises ferro-concrete panels with the sizes 6000 × 1800 mm. The panel consists of rupture and non-rupture parts. Non-rupture part is designed as bearing ribs mounted along the outline of the breaking part, which is implemented as at least two coaxially located recesses in a building wall, one of which, external one, is formed by planes of a regular quadrangular truncated pyramid with a rectangular base, and another, internal one, comprises two slant surfaces, joined by rib, forming a slit. The wall thickness from a rib to an external surface of the building cladding shall be no less than δ =20 mm. Action of shock, explosive load can disintegrate this part of the wall into separate parts. In front of the rupture part, from the external side of the building cladding, a protecting screen from the strengthened material, for example, armour-piercing material is located, which is fixed on, at least, three rods horizontally located and perpendicular to the building cladding, on the ends of which disks are fixed and which pass through the protecting screen holes. The disks located from the right side of rods, are immured into the building cladding, and the disks from the left side of the rods are rested by elastic elements underpinning the protecting screen to the buildings cladding.
EFFECT: invention allows to improve the reliability of operation of rupture devices in case of accidental detonation at the plant.
