Circular foundation pit lined wall formwork construction system and construction method

Abstract

The invention relates to a circular foundation pit lined wall formwork construction system and a construction method. The circular foundation pit lined wall formwork construction system comprises a formwork hanging system and a formwork system, the formwork system comprises an end formwork, a bottom formwork and a side formwork, the formwork hanging system is fixed on a crown beam of a circular deep foundation pit, the formwork hanging system comprises vertical-directional triangular trusses arranged evenly along the crown beam, an annular rail fixed on the vertical-directional triangular trusses, and an electric hoist with a running car, and the electric hoist is fixed on the annular rail and used for hoisting the side formwork; the bottom formwork includes a molded hyperbolic steel bottom formwork and a bottom formwork cross plate support frame for supporting the molded hyperbolic steel bottom formwork; the end formwork includes an end plate, a structural steel support and reinforcement device, a wooden I-shaped beam, lined wall reserved horizontal rebar and a screw; and the side formwork includes a side formwork body, a molded large formwork hook, a steel molded pouring port, anoperation platform, a high-strength screw and a connecting rod. According to the circular foundation pit lined wall formwork construction system, the electric hoist with the running car can design the number and moving positions according to needs, after the assembly of the side formwork body is completed, hoisting to a preset position is conducted through the formwork hanging system, construction is fast, and the cost is low.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a formwork construction system and construction method for lining walls of circular foundation pits. Background technique [0002] In conventional formwork construction technology, large machines such as tower cranes or cranes are used to hoist, install and dismantle the shaped formwork. The shaped formwork is large and heavy, and cannot be operated manually. The tower crane needs to be occupied for a long time during the installation and removal process, which will affect the lining wall. and other normal transportation (horizontal and vertical transportation of steel bars and other materials). Contents of the invention [0003] The purpose of the present invention is to provide a circular foundation pit lining wall formwork construction system, a circular foundation pit lining wall formwork construction system and a construction method, to solve the technical problem of l...
