Abstract

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.

Description

technical field

[0001] The invention relates to a formwork reinforcement technology for high-rise and super high-rise buildings, in particular to a formwork reinforcement method for a large-section frame column with a cross-section above 1000*1000. Background technique

[0002] The conventional frame column formwork installation project adopts the outer hoop of the steel pipe and the center-piercing reinforcement of the pull screw. This reinforcement method is cumbersome, consumes a lot of turnover materials, and the appearance is ordinary after pouring. Especially for frame columns with a large cross-sectional area, due to the large lateral pressure during the concrete pouring process, the outer hoop of the steel pipe is very large, and a large number of fasteners need to be installed to match it. The process is cumbersome and affects the construction progress; The amount of screw used is large, resulting in many holes on the concrete surface that need to be repaired after ...
