FIELD: construction.
SUBSTANCE: in relief package of flexible elements for protective shield of collapsing part of explosion-proof guard of buildings, comprising the bearing rod, one end of which is rigidly fixed by means of the basic disc of bearing rod in the reinforced concrete slab and on the other free end of the bearing rod there is a package of flexible elements for protective shield, bearing rod is perpendicularly and rigidly secured to basic disc fixed in the reinforced concrete slab, and the protective shield through the sealing gasket is mounted on four bearing rods, in this case the guide sleeve is fixed rigidly and perpendicularly by one of its ends, coaxial with the bearing rod and covering it with clearance, and the second end of guide sleeve enters with clearance into the opening of thrust cover of package of the dished flexible elements coaxial with it, which is fixed on the free threaded end of the bearing rod via the lock washer and nut. Package of dished flexible elements consists of serially connected dished flexible members, the inner surface of central holes of which interacts with guide sleeve coaxially arranged relative to them, besides each flexible member of the dished type comprises the dished flexible surface in the form of truncated cone, the large base surfaces of which thrust against each other in pairs, forming the package fixed on the guide sleeve.
EFFECT: increase of reliability and efficiency of collapsing explosion protection devices at emergency explosion at the facility.
