METHOD FOR CONJUGATION OF BRIDGE FLOOR PLATE WITH BEAMS OF BRIDGE FRAMEWORK Russian patent published in 1998 - IPC

FIELD: bridge construction; may be used in mounting of bridge framework. SUBSTANCE: method consists in that placed on bridge framework beams are bearing members elastoplastic during mounting and liable to hardening and made with height exceeding rated height corresponding to theoretic profile of bridge framework floor. Then bridge floor plate is laid on bearing members adjusting to its design position, fixing of mutual position of plate, bearing member and beam by tightening of tie-rods passed through members to be fixed. Fixing members are held for time required for hardening of bearing members. Bearing member is used in the form of bulked body whose one part of volume is filled with plastic composition liable to hardening, while the other part, is filled with flexible members ensuring during mounting period of rigidity of bearing member satisfying the said condition, and load carrying capacity of bearing member of not less than the total load. Setting of plate to design position is combined with the operation of fixing of joined members and is carried out by changing the height of bearing members in tightening tie-rods performed with check of profile of bridge framework floor up to occupation of design position by plate. EFFECT: simplified method of conjugation of bridge floor plate with framework beams, and reduced duration of mounting operations.
