Problems solved by technology

[0002] At present, the general giant structural column formwork still adopts the keel behind the wooden formwork and the reinforcement of the pull bolts to carry out the formwork installation of the structural column. The requirements for the reinforcement technology of the formwork are relatively high, and the quality control of the verticality and flatness of the structural column is relatively difficult. Difficult to grasp, after the demolition of the last shift, many pull screws remain on the surface of the structural column, which needs post-processing, and mold expansion is more likely to occur during pouring, and the removal of the formwork is difficult, and the number of turnovers is low
[0003] Part of the structural column formwork has been reinforced with steel formwork, but a large number of steel pipe scaffolds need to be used to build access and work platforms around the steel formwork, and the installation and removal efficiency is low

Abstract

The invention discloses an integrated prefabricated giant column steel formwork support system, which relates to the technical field of giant column steel formwork support equipment. Combined installation and reinforcement; the main body of the steel formwork is a steel plate, and several vertical and evenly distributed vertical keels are welded on the steel plate. One side of the steel plate is welded with a channel steel group as the main keel in the horizontal direction. The angle steel connected with the adjacent steel formwork, the channel steel group of the two adjacent steel formwork is fixedly connected by the reinforcement. The beneficial effects of the invention are as follows: the system replaces wood with steel, which increases the turnover times of materials and realizes green construction; the combination of the pull-screw can provide effective strength, and also simplifies the later surface treatment; The connection relationship is simple, the installation is simple, and the focus of safety and quality inspection and control is obvious and easy to control.

Description

technical field [0001] The invention relates to the technical field of giant column steel formwork support, in particular to an integrated prefabricated giant column steel formwork support system. Background technique [0002] At present, the formwork of the general giant structural column still adopts the keel behind the wooden formwork and the reinforcement of the tie bolts for the formwork installation of the structural column. It is difficult to grasp. After the last shift is removed, there are many pairs of pull screws left on the surface of the structural column, which require post-processing, and the phenomenon of mold expansion is more likely to occur during pouring, and the removal of the template is difficult, and the number of turnovers is low. [0003] Some structural column formwork has been reinforced by steel formwork, but around the steel formwork, a large number of steel pipe scaffolding needs to be used to set up passages and working platforms, and the inst...
