A hard protection device for the upper formwork system of the core cylinder inner cylinder and its construction method

Abstract

The invention discloses a core tube inner tank upper formwork system hard protection device and a construction method. The core tube inner tank upper formwork system comprises a core tube inner tank, the core tube inner tank is provided with a formwork construction embedding device, a steel corbel is fixed to the formwork construction embedding device and is provided with a hoist, a hoisting steel wire rope is arranged on the hoist, a hard protection construction platform is connected to the lower end of the hoisting steel wire rope, an operation scaffold is erected on the hard protection construction platform, the steel corbel is fixed through the formwork construction embedding device used when the core tube inner tank upper formwork system is used for constructed, and the hard protection construction platform is fixed to the steel corbel; when a core tube wall is firstly constructed, the hard protection construction platform can be driven by the hoist to automatically ascend along with the core tube floor operation face at the lower portion, safety construction of the creeping formwork bottom operation face is guaranteed, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a hard protection device under the formwork system on the upper part of the inner cylinder of the core cylinder, and a construction method thereof. Background technique [0002] In the current super high-rise construction process, the core wall is mostly constructed by self-climbing formwork, in which the self-climbing formwork is attached to the completed core wall and rises layer by layer with the core tube construction. This kind of formwork system, when the concrete reaches the demoulding strength and the formwork is demoulded, the formwork does not fall to the ground, relying on mechanical equipment and supports to climb the formwork and climbing formwork device up one level, positioning and tightening, repeated cycle construction. [0003] In order to maximize the potential of key lines and scientifically utilize the working face, most of the core tube walls are used first, and the inner beams and outer frame floors of th...

AI Technical Summary

Problems solved by technology

[0003] In order to maximize the potential of key lines and make scientific use of the working face, most of the core tube walls are used first, and the inner beams and outer frame floors of the core tube are followed closely by the construction deployment. However, the existing safety problems are: due to The wall of the core tube goes first, especially when the core tube formwork system climbs, the anti-fall flap of the platform needs to be opened. At this stage, it is impossible to completely avoid the phenomenon of small pieces of material falling on the core tube formwork platform. The lower core tube beam plate There are great safety hazards in the hard protection construction platform, and at the same time, the work efficiency is reduced, which is not conducive to the guarantee of the construction period
