STRUCTURE FOR REINFORCE THE BREDGE

摘要

The present invention provides a structure for reinforcing a point of a continuous bridge using a steel bar and a method for reinforcing a point of a continuous bridge using the same. According to the present invention, the structure for reinforcing a point of a continuous bridge using a steel bar comprises: two point girders (100) positioned on both sides of a point (A) of a continuous bridge; a tendon insertion unit (110) into which a tendon (200) for supplying an upward force to the point (A) is inserted; and a connection unit (300) formed between the two point girders (100). The tendon insertion unit (110) penetrates the two point girders (100) and the connection unit (300) and is formed in a downwardly curved shape. The tendon (200) is a steel bar (200a) corresponding to the shape of the tendon insertion unit (110). According to the present invention, a negative moment created on the point of the continuous bridge is offset to construct a structurally stable long span beam.
