FIELD: construction industry. ^ SUBSTANCE: protection device meant for window openings consists of support frame made of steel angle section and rigidly fixed inside the opening in window frame plane, and removable frame made of rectangular steel tube, which is located inside support frame on fastening elements. To inner contour of removable frame there rigidly attached, by means of electric welding, are enclosing elements made of rope and connected to each other in a staggered manner by means of overlaps clamped with braces. Before the enclosing ropes are attached to inner contour of removable frame, rope ends are clamped in pairs with braces, and their end faces are fused by means of electric welding. Extreme enclosing ropes are clamped with steel bushes in the middle of each cell. Inside fixed support frame on its both sides in window frame plane there rigidly attached to the flanges are T-shaped fastening elements. ^ EFFECT: simplifying protection device design, reducing metal consumption, and improving resistance of mounting fasteners inside the opening to breaking. ^ 8 dwg |
