FIELD: protective devices.
SUBSTANCE: invention relates to protective devices used in explosive hazardous and radioactive objects, such as easy detachable and antiblast panels and roofs, and blast shield. Explosion-proof dying construction of protective guard structures of buildings contains reinforced concrete panels, each of which consists of rupture and indestructible parts, herewith indestructible part is made in form of carrier hip-rafters placed along the contour of rupture part, and the destructible part is made in form of at least two coaxial recesses building wall, one of which, external one, is formed by planes of proper quadrilateral truncated pyramid with rectangular base, and the other, internal, is two angled surfaces connected by hip-rafter, forming a slot. Opposite the rupture part, on the outer side of the building enclosure there is a protective shield made from a material with high strength, for example, an armored material which is fixed on at least three horizontally located and perpendicular to the building enclosure support rods, at the ends of which discs which pass through the holes in protective screen are fixed, 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, while the recesses in the wall of the building are filled with heat-and-sound-isolation material and closed by decorative easily collapsed panel. Support rod is made in form of hollow rod with a set of damp flat abutment stops in the internal cavity and is a cylindrical damping element to the ends of which abutment stops are rigidly attached, and the inner cavity is filled with a set of at least two damping flat abutment stops mounted on an elastic axis coaxially disposed with the cylindrical shell, and between the damping flat abutment stops there is at least one cylinder spring whose cavity is filled with vibration cushioning material, for example polyurethane.
EFFECT: increasing the reliability of mounting the explosion-proof screen of the rupture part of the explosion-proof buildings cladding during an emergency explosion at facility.
