FIELD: construction.
SUBSTANCE: device for protection of buildings and structures with the help of damaged structure elements comprises an explosive chamber, in the upper base of which there is a hole covered with an easily removed element. The hole area may vary by screwing of replaceable rings, and the removed element covers the hole in the ring, above which the protective screen is fixed. The second hole is closed with a valve, which is pressed to the hole with the help of an electromagnet and is opened with a spring as contacts open, and the force of valve pressing and spring compression is set so that the total force is equal to the pressure permitted multiplied by the area of the valve hole.
EFFECT: higher efficiency in protection of buildings, structures, process equipment against explosions by increasing performance and reliability of actuation with the help of damaged elements of structures and assessment of efficiency of easily removed barrier blast resistant devices in emergency mode on a facility and provision of such structures return into initial position after an explosion.
