civil engineering, in particular, constructions of protection enclosures for window or door openings. SUBSTANCE: protection enclosure for the door and window openings has movable and fixed rods interconnected by enclosing members, guides located on the opposite sides in the opening plane, and supporting members. The enclosure is provided with two compression springs, which are located on the ends of the fixed rod. The enclosing members are made in the form of wire ropes. The adjacent wire ropes are interconnected by tie-rods in staggered rows. The supporting members are made in the form of shackles that are positioned on the rods and guides. The guides are made in the form of bars. Each of the shackles located on the guides is coupled to the ends of the two adjacent wire ropes, except for the extreme wire ropes. The ends of the extreme wire ropes are coupled to the shackles located on the ends of the movable and fixed rods, positioned on which are also the shackles coupled to the tie-rods of the extreme wire ropes. The shackles on the ends of the fixed rod are positioned for engagement with the compression springs. EFFECT: simplified construction and reduced specific quantity of metal per structure. 7 dwg
