Along the out edge of the Xinzheng International Airport terminal T2 , 124 reinforced concrete independent oblique columns are designed, in which the biggest section size is 1 200mm × 1 600mm, the cantilevered height is 18?2 ~28?6 m and the wholly outward inclination is 6?75 ° . Through detailed design, force calculating and 3d simulation, this paper mainly introduces construction technology of integral self?lifting type template reinforcement. The technical scheme has new form, accurate positioning and simple materials. And it even can effectively guarantee the inclination of columns, increase the efficiency of the construction as 1?5 times with perfect construction quality. This technical proposal offered a new idea for construction of super?high large?section independent oblique columns.
