FIELD: construction of storehouses for valuables; manufacture of protective slabs, doors, ceilings, floors and barriers. ^ SUBSTANCE: proposed anti-burglary device has cavity with rods whose ends are connected with inner surface of front wall of body and filler made in form of laminar structure assembled in one or several stacks. Stacks are formed by connecting the veneer sheets, metal screen and end metal sheet followed by making through holes for receiving the rods. End metal sheet for each multi-layer stack is connected with rods. Laminar structure is formed in cavity of body longitudinally relative to its front wall. Laminar structure forms non-detachable joint together with rods. ^ EFFECT: enhanced efficiency of protection; reduction of mass; low cost. ^ 11 cl, 5 dwg |
