FIELD: construction. ^ SUBSTANCE: branched pedestrian bridge includes at least three spans arranged in plan at the angles to each other and having at least one rectilinear main span, at least two spans on branches, at least one unit of their coupling, where not more than three spans meet, at least one longitudinal system of main bearing structures in each of them, at least three units of bridge ends coupling with pavement, combined with supports, including supports and devices of pedestrians lifting onto bridge. All spans are split, spans on branches are arranged as rectilinear. Angles between longitudinal axes of each pair of adjacent spans in unit of their coupling are in the range of 110-130. ^ EFFECT: invention provides for free horizontal passage over crossing obstacles between any two points of crossing. ^ 6 cl |
