FIELD: construction.
SUBSTANCE: invention relates to bridge crossing structures, as well as structures of railway platforms made from composite materials. Bearing structure, designed as basic frame with below flooring, is coated with fire-prevention protection, made in the form of multilayer panels, each of which consists of outer shell made of low-combustible composite material reinforced with fiber glass of E or E-CR, or S, or C type or with silica, quartz, aramid or basalt fibres and thermosetting polymer matrix presented by epoxy, or phenol, or polyester, or vinyl ether, or urethane binders coated on external surface with fire-retardant composition, and inner part made of incombustible fire-resistant layer based on inorganic mineral materials.
EFFECT: two versions of design are availible, which solve technical problem of providing fire safety.
