STAND FOR TESTING DESTRUCTIVE ELEMENTS OF BUILDING AND FACILITY STRUCTURES Russian patent published in 2017 - IPC E04B1/92 A62C3/00 F16K17/00 

Abstract RU 2635689 C1

FIELD: construction.

SUBSTANCE: stand contains an explosive chamber, in the upper base of which there is a hole, which is overlapped by easy detachable destructive element, consists of an explosive chamber, which is a metal vessel with a volume equal to 500÷1000 cm3, with wall thickness of 7÷8 mm. In the upper base of the container there is a hole overlapped by an easy detachable element, and the hole area can be changed by screwing in replaceable rings. The detachable element overlaps the hole in the ring, which establishes the safety screen and the second hole is blocked by a valve which is pressed against the hole using electromagnet and opened by a spring when contact breaking. In one of the end walls of the explosive chamber there is a hole for a connecting piece, which secures a tube of a blower, cut off with a tap, and in the other opposite end wall of the explosive chamber there is a hole for a connecting piece for a tube, cut off by a tap, which serves to maintain the air pressure in the chamber during the evaporation of liquids. The area of the hole can be changed by screwing in interchangeable rings and the detachable element overlaps the hole in the ring, above which the security screen is fixed. The easy detachable element contains a metal armoured frame with metal armoured plating and a filler, with the ends of the frame having four fixed pipe supports. In the cover of the explosive object, four support bars are rigidly fixed, which are telescopically inserted into the fixed pipe supports of the panel, with the filler being made in the form of an air-lead disperse system. Lead is made in the form of crumbles; the support bars are made elastic. A damping plate is attached to the support bars of the easy detachable element, telescopically inserted into the fixed pipe supports, embedded in the panels, to which stop plates are welded for fixing the limit position of the panel. A buffer gear in the shape of a cone, the vertex of which is on the axis of the opening, is attached to the damping plate opposite the panel and in the direction of the shock wave. The buffer gear for fixing the limit position of the panel, attached to the damping plate, is made in the form of a hollow cone, the vertex of which is on the axis of the opening, with the lateral hollow cone conical surface having orifice holes for damping the shock wave.

EFFECT: increase in the effectiveness of protection of buildings and facilities.
