SUPPORT STRUCTURE OF CURVILINEAR SCAFFOLD BRIDGE Russian patent published in 2003 - IPC

FIELD: bridge building. SUBSTANCE: proposed support structure of curvilinear scaffold bridge includes supports and bridge framework resting on assembled collar beam. Novelty is that collar beam in trapezoidal in plan in form of turned-over trapezoidal trough with flanges and is arranged in body of bridge framework which rests on lower flanges of collar beam. Support, from side of smaller radius of scaffold bridge curvilinear in plan, contains pole whose lower round section joints with columnar foundations, and upper section of pole having elliptical form in place of contact with collar beam, is orientated by its larger semiaxis tangentially to curvilinear axis of scaffold bridge in place of it intersection with axis of collar beam. Support, from side of larger radius of scaffold bridge curvilinear in plan, contains assembly of two poles orientated by plane tangentially to curvilinear axis of bridge in plane of intersection with collar beam axis. EFFECT: improved operation of collar beam in places of joining with posts subjected to design improvements fro use in curvilinear scaffold bridge. 3 cl, 3 dwg
