Problems solved by technology

[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.

Abstract

The invention relates to a circular concrete formwork that can be assembled, comprising a base, a standard segment, an end head and a handle. The end head, the standard segment and the base are arranged in sequence from top to bottom, and the outer wall of the end head, the standard segment and the base are respectively There are transverse rib a, transverse rib b and transverse rib c, and a plurality of notches are provided on transverse rib a, transverse rib b and transverse rib c, and one end of part of the handle extends into the transverse rib through the notch on transverse rib a. In the notch on the rib b, and by rotating the preset angle, the end head and the standard segment can be detachably connected; one end of the part of the handle extends into the notch on the transverse rib Rotate a preset angle to allow the standard segment and base to be detachably attached. Environmentally friendly and durable, high strength, corrosion resistance, light weight, high turnover, not easy to deform, good concrete forming effect, convenient disassembly and assembly, convenient transportation, economical and practical, effectively solve the traditional round steel formwork. Heavy, cumbersome assembly, construction Problems such as low efficiency and weak reinforcement and easy deviation of circular wood formwork.
