TEMPORARY STRUCTURE AND PRECAST CONCRETE BEAM OF PYLON SETTING METHOD USING THE BRACKET

摘要

A temporary construction bracket installation structure and a method for installing a tower PC(Precast Concrete) cross beam of a cable stayed bridge using a temporary construction bracket are provided to confirm that the horizontal beams of the tower are easily constructed, to reduce construction time, and to set the position of the horizontal beams easily using horizontal supporters of temporary construction brackets. A temporary construction bracket installation structure comprises temporary construction brackets(100), prestressing steel rods(210), and sheath pipes(220). The temporary construction brackets include vertical and horizontal supporters, and inclined supporters for connecting the vertical and horizontal supporters. The prestressing steel rods fix a lower structure contacted with the vertical supporters. The sheath pipes are buried in each part through which the prestressing steel rods pass. Fixing bolts(230) are fixed at the lower structure.
