FIELD: construction, particularly safety enclosures to provide thief-protection of window openings in buildings of different type.
SUBSTANCE: protective grid comprises support members and vertical rods arranged in-between. The vertical rods are connected with each other through enclosing members. The support members include cross-bars and Ω-shaped links with orifices firmed at ends thereof. The orifices are adapted to receive above rods. The links are in vertical planes and alternate so that they form mirror images of each other and central projecting part of each upper link is joined with that of lower link and create closed loops in vertical plane. Cross-bars or links are located in each section defined by two adjacent rods so that sections with links and sections with cross-bars alternate in section aperture plane. End parts of cross-bars are located between end parts of links adjoining thereto from top and bottom sides in joints of enclosing member connection with rods so that united connection unit is formed.
EFFECT: increased structural rigidity.
