METHOD OF FACILITY PROTECTION AGAINST EXPLOSIVE IMPACT WAVE AND DEVICE FOR ITS REALISATION Russian patent published in 2015 - IPC F42D5/45 

FIELD: construction.

SUBSTANCE: an obstacle is placed between the protected facility and source of explosion in the form of a plate structure, comprising four vertical steel supports, between which evenly at height of supports and in parallel to each other there are steel plates fixed and arranged at the angle α=30-80° to the horizon with a pitch determined on the basis of condition of screen creation by plates in the form of a single surface without overlaps and omissions. Besides, resistance of the obstacle to bending is provided by installation of struts on supports with fixed-jammed lower ends and upper ends hingedly or stiffly fixed on the supports.

EFFECT: design of the device makes it possible to divert direction of an impact wave above a protected facility, to reduce force of impact wave effect at an obstacle, load from an impact wave is distributed along the plates and changes direction of effect depending on the angle of their installation on supports.
