A reinforcing method for U-bar hoop formworks of a large-section frame column mainly comprises the implementation steps of 1, formwork design and checking calculation, 2, formworks arrangement, numbers giving and piling; 3, U-bar hoop
processing, 4, pull screw manufacture, 5, column axis determination and elevation measurement, 6, column root formwork
processing, 7, quality inspection, 8, erection of a support frame body, and 9, installation of the column formworks. The reinforcing method for U-bar hoop formworks of a large-section frame column fully utilizes rigidity and strength of U-bars, effectively controls section deformation of the frame column, avoids influence on building appearance quality caused by holes formed by penetrating the penetrating pull screws through components, solves the quality problems of jig displacement, formwork expansion,
slurry leakage and the like to some extent, and meanwhile reduces use quantity of fasteners. All the construction materials can be reused, and cost is saved. The reinforcing method for U-bar hoop formworks of the large-section frame column is simple to operate and simple and easy in procedure, not only effectively shortens construction periods, improves quality and saves the cost, but also is simple in process, practical and reliable.
