EXPLOSION-PROOF DESTRUCTIVE CONSTRUCTION OF BUILDING GUARDS Russian patent published in 2014 - IPC E04B1/92 

Abstract RU 2522841 C1

FIELD: construction.

SUBSTANCE: in safety destructive construction of guard, containing concrete panels with size of 6000×1800 mm, panel consists of destructive and nondestructive parts, in this case the nondestructive part is made in the form of load bearing stiffeners, located along the contour of collapsing part, and the collapsing part is designed in the form of at least two coaxially located recesses in the wall of building, one of which is outer formed by planes of the correct quadrangular truncated pyramid with rectangular base, and the other, inner, represents two inclined surfaces connected by stiffener with formation of groove, in this case the wall thickness from stiffener to outer surface of building guard shall be at least of δ=20 mm, in this case when exposed to explosive shock load, this wall section may be divided into separate parts, and in front of the destructive part, from outer side of the building guard there is a protective shield made of high-strength material, for example armour-piercing material, which is fixed on at least three rods horizontally disposed and perpendicular to the building guard, at the ends of which disks are fixed, and which pass through the openings in the protective shield, besides the discs located from the right side of rods are walled in the building guards, and elastic elements holding up the protective shield to the building guard, thrust against the discs from the left side of rods.

EFFECT: increase of response reliability of collapsing explosion protection devices at emergency explosion at the facility.
