APPARATUS FOR INTRODUCING PRESTRESS INCREASING ENDURING FORCE BY MOVING AXIAL LINE OF ARCH RIB IN ARCH BRIDGE AND METHOD FOR REGULATING ARCH RIB USING THE APPARATUS

摘要

The present invention, if the arch want to increase the arch effect of the load carrying capacity reinforcement and new bridge due to the aging of the bridge Bridge, by applying peuriseuteuresing by yuapjaek at both ends of the arch rib to position the axis of the arch rib upwardly rigidity of the overall structure scheme to the to increase there is provided an arch peuriseuteuresing introduction apparatus and method using the same for adjustment arch ribs to enhance the load carrying capacity of the bridge.; Peuriseuteuresing introduction device for arch bridge according to the invention with a pair of ribs located in the arch on the left and right branch portions; So as to support the lower arch ribs in the horizontal and at the same time placed in the arch of the foot and the rib formed in a rectangular plate; One pairs of direction changing of the block that is securely fixed to the outer side of each end of the arch and rib; As soon tightly positioned between the direction switching blocks of the two sides at the same time provided to apply a predetermined force peuriseuteuresing jack; Characterized by consisting of a guide block which is fixed arranged between the bottom and supporting the direction conversion block.; Further, by adjusting arch ribs method using peuriseuteuresing introduction device for arch bridge according to the present invention properly adjusts the jack is provided between both ends of the arch ribs, is by modulation of the jack in the direction conversion block in close contact with the jack under the as soon along the rail of the position block guide moving to a predetermined position simultaneously with the movement of the direction conversion block added peuriseuteuresing force to the arch rib integrally connected to the direction switching block the axis of the arch rib than the original arch rib axis characterized in that adjusting the position appropriately upwardly.
