FIELD: construction.
SUBSTANCE: framework of bridge includes glued beams, armoured concrete slab of carriageway, stiffening diaphragm, transverse connection and bearing parts of beams. The new in bridge structure is that glued beams has complex cross-section including two glued batches made of boards with non-addiced internal surfaces and glued between them interlayer made of polymer with located in it reinforcing cage. Top part of framework rods is placed in armoured concrete slab of carriageway, and its bottom part is connected to bearing parts of beams.
EFFECT: rising of bearing capacity and rigidity of framework of bridge and reducing of its manufacturing work content.
