REINFORCING STRUCTURE OF PIER TABLE OF ARCHED BRIDGE SPAN Russian patent published in 2013 - IPC E01D22/00 

FIELD: construction.

SUBSTANCE: reinforcing structure of a pier table of an arched bridge span includes arches that rest with their ends against permanent bridge supports, support stands, a beam grid, made of longitudinal and transverse beams and longitudinal beams of filling between spans, resting on longitudinal beams,- and a traffic area with movement joints. Under the transverse beam, which is extreme in the span and adjoins the pier table, there is a flat reinforcement truss mounted, attached to support stands, between the extreme transverse beam in the span that adjoins the pier table and the flat reinforcement truss there are additional longitudinal beams that rest on the flat reinforcement truss and are brought to the transverse beam arranged in the middle part of the span. On additional longitudinal beams there are additional transverse reinforcement beams installed, against which ends of longitudinal beams of filling between spans via tangential support parts of higher movements rest, and via wedged packages of steel sheets - ends of existing longitudinal beams adjoining the pier table of the span. The flat reinforcement truss has bearing capacity that is not lower than the bearing capacity of the transverse beam, which is extreme in the span and adjoins the pier table.

EFFECT: higher bearing capacity of an arched bridge span.
