PROTECTIVE STRUCTURE Russian patent published in 1997 - IPC

FIELD: construction of surface or buried protective structures; applicable at fire- and explosion-hazardous objects. SUBSTANCE: structure has inclined beams from channel hinged by their upper ends with the help of supporting pins, and resting on shaped supporting-connecting members hinged by means of supporting pins with supporting members. The latter are interconnected by means of spring of large stroke secured to supporting pins and passed through channels of guide metal pipes-limiters connected by their one end with supporting members and installed from both sides into channels of supporting metal pipes with gap. Gap is filled with annular spacer from yielding material. Secured in longitudinal direction to upper flanges of inclined beams is furring from metal channels. Fitted on furring is net of plastic wire and covered from atop with layer of yielding material coated with protective film. Shaped supporting-and-connecting members are secured to lower ends of inclined beams from channel by means of coupling bolts. As a result, dynamic effect is considerably reduced (due to organized yielding of structure) and protective properties are considerably increased. Besides, such a technical solution allows production of more flexible and mobile systems of protection on objects, and perform their assembly and disassembly without use of hoisting equipment. EFFECT: higher protective properties of structures, reduced their weight, higher degree of assembly and disassembly intensity and provision of more flexible and mobile protective system on fire and explosion-hazardous objects. 2 cl, 1 dwg
