Circular concrete formwork capable of being assembled and reinforcement method

Abstract

The invention relates to a circular concrete formwork capable of being assembled. The circular concrete formwork comprises a base, a standard segment, an end and handles, wherein the end, the standardsegment and the base are sequentially arranged from top to bottom; the outer walls of the end, the standard segment and the base are provided with transverse ribs a, transverse ribs b and transverseribs c respectively, and the transverse ribs a, the transverse ribs b and the transverse ribs c are each provided with a plurality of notches; one ends of part of the handles extend into the notches in the transverse ribs b through the notches in the transverse ribs a and rotate by a preset angle to make the end detachably connected with the standard segment; and one ends of part of the handles extend into the notches in the transverse ribs c through the notches in the transverse ribs b and rotate by a preset angle to make the standard segment detachably connected with the base. The circular concrete formwork is environmentally friendly, durable, high in strength, resistant to corrosion, low in weight, capable of being recycled many times, not liable to deformation, good in concrete forming effect, convenient and fast to disassemble and assemble, convenient to transport, economical and practical, and effectively solves the problems that a traditional circular steel formwork is thick and heavy, troublesome to assemble and low in construction efficiency and a circular timber formwork cannot be firmly reinforced and is liable to deviation.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an assembleable circular concrete formwork and a reinforcement method. Background technique [0002] Cylindrical formwork is often used in columnar concrete pouring, such as engineering pile connection projects, bridge pier projects, and construction of cylindrical column projects, etc., while traditional cylindrical steel formwork is heavy and cumbersome to install and disassemble. Use hoisting machinery, thus resulting in reduced construction efficiency. The traditional cylindrical wooden shaped formwork is composed of two semi-circular mother-in-law interface wooden formwork assembled, and is tightened and reinforced with steel bands. Since the formwork is made of wood, and the mother-in-law interface is very easy to enter the mortar and be damaged during construction, it cannot be used. The number of times of use is guaranteed, and the basic turnover is more than four...

[0002] Cylindrical formwork is often used in columnar concrete pouring, such as engineering pile connection projects, bridge pier projects, and construction of cylindrical column projects, etc., while traditional cylindrical steel formwork is heavy and cumbersome to install and disassemble. Use hoisting machinery, thus resulting in reduced construction efficiency

The traditional cylindrical wooden shaped formwork is composed of two semi-circular mother-in-law interface wooden formwork assembled, and is tightened and reinforced with steel bands. Since the formwork is made of wood, and the mother-in-law interface is very easy to enter the mortar and be damaged during construction, it cannot be used. The number of times of use is guaranteed, and the damage is more serious if the basic turnover is more than four times, and the material of the wooden formwork itself is limited. When the side pressure is too large, it will cause serious deformation and crack the left and right semicircular formwork.
