METHOD FOR COMPOSITE REINFORCED CONCRETE BRIDGE SPAN STRUCTURE CONSTRUCTION AND COMPOSITE REINFORCED CONCRETE MEMBER FOR SPAN STRUCTURE CONSTRUCTION Russian patent published in 2006 - IPC E01D12/00 E01D2/02 

FIELD: building, particularly to construct bridges characterized by a combination of structures.

SUBSTANCE: method involves producing and mounting main steel beams; producing, mounting and joining composite reinforced concrete bridge panel members of roadway including steel connection members; joining the connection members to main steel beams with the use of high-strength bolts. Bridge roadway panel is produced in two stages. First of all composite reinforced concrete members are mounted. Then cast-in-place reinforced concrete layer and leveling layer are laid on the bridge roadway panel members, wherein composite members are joined by free contact operation without reinforcement connection. Composite reinforced concrete members have thicknesses less than total thickness of bridge roadway panel. Cast-in-place concrete layer thickness is determined from corresponding relation. Composite reinforced concrete member for composite span structure construction comprises panel as viewed in plane. The panel has ends with lengths equal to span structure width, stiffening ribs formed along panel ends, steel connection members of double-tee sections directed parallel to panel sides. Connection member has welded upper belt and lower belt including two angle members connected to wall by high-strength bolts and provided with orifices to connect thereof to main beam of span structure with high-strength bolts. Connection reinforcement is formed on upper panel surface. Stiffening ribs are displaced relatively panel end for distance determined from corresponding relation. One stiffening rib is displaced outsides and defines groove, other stiffening rid is displaced insides and creates extension to joint composite members one to another. The steel connection members are located between the stiffening ribs and have heights exceeding that of stiffening ribs.

EFFECT: improved technological efficiency of bridge construction due to possibility to solve joint grouting problem.
