METHOD FOR ASSEMBLING OVER-PIER PART OF BRIDGE SPAN STRUCTURE Russian patent published in 2005 - IPC

FIELD: building, particularly to construct steel reinforced concrete span structures.

SUBSTANCE: method involves mounting blocks formed as reinforced concrete flooring panels by moving thereof in horizontal direction with the use of pushing means across bridge span, wherein before panels installation on support span parts panel is laid on sleds with the use of load-lifting means, sleds are installed on track, guiding tracks are placed on sleeper grid consisting of wooden studs and two transversal members, rollers are arranged between sleeper grids; installing supplementary columns and four jack posts in addition to main supports. Flooring panel movement is performed with the use of pushing means which displaces sleds up to span to be overlapped. After that flooring panel is lifted by means of jack posts, sleds are removed and displaced into their initial position. Then track is rolled, flooring panel is lowered on bridge piers with the use of hydraulic cylinders of jack posts; free jack posts are dismounted and mounted in the next bridge span simultaneously with supplementary columns installation. Track is placed on previously installed flooring panel with sleds on which next flooring panel is laid. All above operations are repeated.

EFFECT: reduced time of bridge assemblage in urban areas.
