A Simple Supporting Method for Concrete Cylindrical Formwork

Abstract

The invention discloses a simple supporting method for a cylindrical concrete formwork, and belongs to the technical field of building concrete formworks. An inner flat iron hoop, supporting steel tubes and an outer flat iron hoop are involved in the method. The method is characterized in that a bamboo wood formwork is further involved in the method and is of a cylindrical structure formed by splicing two or more composite bamboo glue formworks; the inner flat iron hoop is fixedly installed on the periphery of the bamboo wood formwork, and the supporting steel tubes are fixed to the inner flat iron hoop through steel tube fasteners and are sleeved with the outer flat iron hoop. The cylindrical concrete formwork is compact in structure, easy to machine, not prone to deformation, light in weight and low in cost, the surface of poured concrete is smooth, and dimension errors are small; the supporting components are high in circulation rate, convenient to assemble and disassemble and high in working efficiency; no complex outer supporting structure is needed, and the cylindrical concrete formwork is suitable for narrow sites and is convenient to maintain and clean after being dismantled.

Description

technical field [0001] The invention relates to the technical field of building concrete formwork. Background technique [0002] Tall independent columns bring people the enjoyment of beauty. In order to meet the aesthetic needs of the public, concrete columns are widely used in building structures. The traditional column-shaped steel formwork and wood formwork support systems can no longer meet the requirements of modern building construction. Because the shape is round It brings a lot of inconvenience to the construction, especially the formwork installation, and increases the construction difficulty. At present, there are some targeted patents and researches: [0003] The Chinese patent with the publication number CN103184794A discloses a construction method for rapid formwork support of a cylindrical hoop-type paired wooden formwork, which consists of the position of the bullet post, the placement of the grout backing plate, the leveling of the cylindrical formwork range...

AI Technical Summary

Problems solved by technology

However, if the wooden square is used as the formwork support, nails are needed to fix the wooden square and the formwork, the construction speed is slow, and the strength of the wooden square is low, easy to deform, and the turnover rate is low

The strength and rigidity of the wooden square support are not as high as the steel pipe support. For tall formwork, the effect of the wooden square support formwork system is not easy to guarantee
