STRUCTURE FOR COUPLING OF WOOD-AND-REINFORCED CONCRETE SPAN WITH BRIDGE ABUTMENT Russian patent published in 2009 - IPC E01D19/02 

FIELD: construction, road engineering.

SUBSTANCE: invention is related to bridge engineering, in particular to structure for coupling of wood-and-reinforced concrete span with bridge abutment. Structure for coupling of wood-and-reinforced concrete span with bridge abutment and adjacent road, including carper, temperature-continuous or split reinforced concrete slab and wood-glued ribs connected to each other by discretely installed anchors, cabinet part installed on piles, having structural gap with ends of wood-glued ribs and backwall, onto which transition slabs are supported. Movement joint of trafficway is offset beyond the limits of bridge seating platform of abutment. Reinforced concrete slab simultaneously rests on wood-glued ribs and top of backwall, and elastic water-impermeable high-strength woven material is glued to adjacent sections of span slabs and transition slabs and into joint between them in the form of fold.

EFFECT: improved durability of operation of wood-and-reinforced concrete span coupling with bridge abutment.
