METHOD FOR TEMPORARY SPAN STRUCTURE SECURING DURING ASSEMBLAGE THEREOF WITH THE USE OF TEMPORARY STRESSED HIGH-STRENGTH REINFORCEMENT BUNDLES Russian patent published in 2005 - IPC

FIELD: bridge building, particularly structural or constructional details of bridges.

SUBSTANCE: method involves forming channels in pier and in span structure to be mounted, wherein channel axes face each other; registering channel axes; arranging high-strength reinforcement in channels of span structure and pier so that anchor connections may be installed at least on one reinforcement end and/or demounted from it; connecting another reinforcement end to reinforcement tightening means; tensioning temporary reinforcement and compensating force caused due to span structure cantilevered position on pier; performing span structure securing to pier and connecting longitudinal reinforcement thereof; removing stresses from temporary prestressed bundles; demounting anchor connections and removing temporary stressed reinforcement bundles from channels.

EFFECT: increased building rate, increased connection reliability, reduced labor inputs, possibility to use reinforcement bundles in main bridge structure parts.
