Super-high column formwork steel reinforcement overall-hoisting construction method

Abstract

The invention discloses a super-high column formwork steel reinforcement overall-hoisting construction method. The super-high column formwork steel reinforcement overall-hoisting construction method comprises the steps that S1, an independent foundation is poured, a plurality of corrugated steel pipes are pre-buried in the independent foundation, the independent foundation is cured, the corrugatedsteel pipes are reserved to exceed the surface of the independent foundation by 5 mm to 10 mm, and column formwork dimension lines are set out; S2, stirrups are manufactured and positioning ribs arewelded, and welding positioning is conducted to manufacture to form a steel reinforcement cage; S3, the steel reinforcement cage is pre-hoisted to judge the relative position accuracy of steel reinforcements at the bottom of the steel reinforcement cage and the corrugated steel pipes, and the steel reinforcement cage is subjected to formwork closing through two C-shaped column formworks; and S4, high-strength grouting materials are poured into the pre-buried corrugated steel pipes though a sizing funnel; and S5, the steel reinforcement cage is hoisted to the independent foundation, the steel reinforcements at the bottom of the steel reinforcement cage are inserted into the corrugated steel pipes pre-buried on the independent foundation, the grouting materials are cleared and removed, concrete is poured, and curing is conducted. A poured super-high column is high in rigidity, less in splicing seams and excellent in forming quality, overall hoisting is adopted in the super-high column formwork steel reinforcement overall-hoisting construction method, and thus the centralized machining degree is high.

Description

technical field [0001] The invention relates to the technical field of building construction, and more particularly, to a construction method for integral hoisting of superhigh column formwork reinforcement. Background technique [0002] Among the vertical load-bearing components, reinforced concrete components are currently the most used load-bearing form, and in the concrete pouring construction of super-high columns with large cross-sectional dimensions, the one-time pouring forming technology is still a major difficulty in the field of concrete construction. If the traditional method is used for construction, a large number of scaffolding needs to be erected, and there will be more high-intensity work; if the traditional formwork is used to pour the column, there will be many joints, and the bottom of the ultra-high column is easy to expand the mold, and the molding quality is difficult to control. [0003] When faced with such large-scale concrete structural columns, mo...
