FIELD: construction.
SUBSTANCE: invention relates can be used in structures of composite reinforced concrete superstructures during construction, reconstruction and repair of bridges associated with widening of their roadway dimensions. Composite reinforced concrete bridge superstructures includes composite reinforced concrete beams from metal beams combined with reinforced-concrete slabs of the carriageway by means of stops, combined with each other by triangular transverse links from struts and braces, a roadbed with a concrete leveling layer. Braces of triangular transverse links are fixed by upper ends on shaped sheets attached to inclined parts located to inclined sides to end surfaces of reinforced concrete slabs of roadway. Cover plates of adjacent reinforced concrete plates of the roadway are connected to each other by directed vertices downwards by wedge-shaped metal plates projecting above the upper edge of reinforced concrete slabs of the carriageway in the thickness of the leveling concrete layer of the roadbed.
EFFECT: reduced labor intensiveness and material intensity of composite reinforced concrete bridge superstructures.
