Cylindrical wood formwork concrete pouring construction method

Abstract

The invention provides a cylindrical wood formwork concrete pouring construction method, and relates to the technical field of building engineering construction. The cylindrical wood formwork is formed by sequentially setting the steps of formwork design, processing, positioning and paying-off, formwork assembly, formwork reinforcement, perpendicularity calibration, formwork pre-acceptance, concrete pouring, formwork removal and maintenance, and is formed by splicing two bent plates with semicircular arc lengths; a concave-convex opening design is adopted between connectors, formworks are installed in a staggered mode, positions of the horizontal connectors of an upper formwork and a lower formwork are reinforced through steel belts, meanwhile, the formworks are vertically positioned, stress of the formworks forms a whole, and the secondary reinforcing effect is achieved. Due to the fact that the formworks are installed in a staggered mode, the horizontal connectors of the upper formwork and the lower formwork are reinforced through the steel belts, the connectors are horizontally covered with the steel belts, it is guaranteed that the connectors are located in the middles of the reinforced steel belts, and the stability and construction effect of the formworks are greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of building engineering construction, in particular to a concrete pouring construction method of a column wood formwork. Background technique [0002] In the construction of cylindrical buildings, steel round formwork has always occupied a monopoly position, and no substitute products have come out for many years. However, due to the limitations of steel formwork, such as high cost and transportation cost, heavy weight, cumbersome disassembly and assembly, and manpower occupation, it has also become a relatively complicated process in the construction process; although the novel glass fiber reinforced plastic formwork has solved the problem of heavy weight and manpower in recent years However, it has disadvantages such as easy formation of bubbles, large arc deformation, and easy damage. After years of engineering practice, on the basis of the utilization rate and cost of cylindrical steel formwork and the ...
