FIELD: spanning devices.
SUBSTANCE: invention relates to the field of spanning devices, namely to the collapsible bridges. Span structure consists of two folding in halves steel tracks, interconnected by a folding strut and cable ties. Each track consists of two half-tracks, articulated at the lower belt. At the bottom of each half-track beams made of light composite material, for example, carbon fiber reinforced plastic or glass fiber plastic, are installed. As a roadway, a road plate made of a composite material is applied, and the inter-tracks gap is covered by made of composite material inter-tracks shields. Each piece of composite material is made unified.
EFFECT: application of the technical solution will allow to reduce the span structure weight and, due to this, to increase the span structure length, and also to make a span structure with a continuous carriageway, which will allow to increase the span structure throughput capacity.
