METHOD OF INDUSTRIAL BUILDINGS EXPLOSION PROTECTION Russian patent published in 2018 - IPC E04B1/92 

FIELD: methods of explosion protection.

SUBSTANCE: invention relates to safety devices used in explosive and radioactive facilities, such as easy detachable panels and roof, blast guards and shields, excessive pressure valves. Result is achieved by the fact that in the method of explosion protection of industrial buildings, installation is carried out in the enclosing structures of the building, where explosive and fire hazardous equipment is functioning, explosion-proof elements, explosive and fire hazardous equipment installed on the foundation of the building, and in the side and upper fences of the production building, explosion-proof elements are made, and for side fences, explosion-proof elements are arranged in the form of safety breaking structures of the fencing of buildings, and for upper enclosures – in form of explosion-proof boards on roof or attic floor of building with explosive objects located therein, explosion-proof elements are made in the form of an explosion-proof plate containing a metal armored frame with a metal armored shell and a filler-lead that has four fixed pipe-supports in the ends, and in coating of building there are embedded rigidly four bearing rods, which are telescopically inserted into fixed pipe-supports of panel, at that, the filler is made in form of air-lead disperse system, the said lead is shaped as frit while the load-bearing bars are flexible, explosion-proof elements are made in the form of a protective collapsible fencing structure containing reinforced concrete panels, each of which consists of destructible and non-destructive parts, wherein latter is composed of bearing ribs arranged along outline of collapsible part, latter is composed of at least two coaxial recesses in building wall, one of which, external, is formed by planes of right quadrangular truncated pyramid with rectangular base, and other – internal – represents two inclined surfaces connected by a rib to form a slot, wherein wall thickness from outer surface of building enclosure must not be less than δ=20 mm, wherein at impact, explosive load said wall section can be divided into separate parts. To the sheet-stoppers of the support rods it is attached the elastic-damping, disintegrating elements of a single action, by means of a damping base, they are fastened with screws, and a single-action bushing is fastened to the base, coaxially with the stem, by means of screws, and it is made of a fragile, collapsible material, for example porcelain, and the resilient part of the fracturing element is made in the form of at least three leaf springs and is placed between the stopping sheets and the hub-type clamping element with grooves for fixing one end of the springs, while the second end of each spring by means of hinges is fixed on the stop sheets, and the springs are arranged with a slope of order of 15÷45 ° in the direction of an elastically damping, disintegrating element of a single action.

EFFECT: increased reliability of operation of personnel in highly explosive premises.
