Abstract
Description
Technical Field
[0001] The invention relates to an independent rectangular concrete column cast-in-place formwork system, in particular to an anti-torsion reinforcement system of an ultra-high independent rectangular concrete column cast-in-place formwork, and belongs to the technical field of building construction formworks. Background Art
[0002] In the large-span factory building with cast-in-place reinforced concrete structure, there are independent cast-in-place concrete rectangular columns with a height greater than 6 meters and a cross-section of 0.7 meters × 0.7 meters. This type of column is called an ultra-high independent rectangular concrete column. Its construction process is: first set up a full-floor support frame, then tie the column reinforcement, and finally support the column concrete casting formwork from bottom to top on the outside of the column reinforcement. On the outer template, the template is reinforced with a clamp-type steel back rib adjustable buckle every 50 cm. Since the intervals of the clamp-type back rib buckle are independently set horizontally, it can only ensure that the rectangular cross-section of the template at the clamp remains unchanged, and it does not have the function of resisting the torsion of the column template in the up and down directions. When the ultra-high independent rectangular column template is supported as a whole, the column concrete is poured in layers at the top of the column, and the beam reinforcement of the longitudinal and transverse frame beams is arranged in the column top template. The intersection density of the column and beam reinforcement in the template is very large, so that the vibrating rod of the concrete vibrator cannot be inserted from the center of the upper port of the column template into the cast-in-place concrete for vibration. At the construction site, the vibrator is extended from the four corners of the column top into the cast-in-place concrete pouring section below to vibrate the cast-in-place concrete; the eccentric vibration of the vibrating rod within the ultra-deep range will cause uneven force on the outer column formwork where the vibrating rod is located, which is very likely to cause the column formwork at this location to loosen and deform; in addition, the vibrating rod head of the vibrator is likely to hit the steel bars and formwork in the column during vibration, and the strong vibration force increases the deformation of the column formwork at this location; the various clamp back-rib fasteners outside the existing column formwork are independently arranged horizontally from each other, and there are no measures to limit the distortion and deformation of the formwork in the vertical direction. When the column formwork is too high, the above factors will directly cause the column formwork to distort and deform in the vertical direction. After the concrete is poured, the ultra-high concrete column will be twisted, causing serious construction quality problems; how to solve the problem that the support system of the ultra-high column formwork is prone to distortion and deformation during concrete pouring has become a difficult problem that urgently needs to be solved on site.
