FIELD: bridge building.
SUBSTANCE: invention relates to the field of bridge building and can be used in the design and construction of arched bridges and bridge structures. Support assembly of the arch bridge secures the concrete pipe arch to the foundation. Between the concrete pipe arch and the foundation, a concrete boss is made. Outlets of the reinforcing frame are brought out of the arch into the foundation; at that, a cross of diametrically opposite rods of the reinforcing frame is made by bending them, due to which a plastic hinge is formed at the points of the cross of the reinforcing rods.
EFFECT: improving strength properties of the support assembly, simplifying the assembly design, reducing material consumption, increasing bearing capacity of the bridge, reducing assembly time.
