Construction method of thin-wall steel cylinder hollow tower column

Abstract

The invention provides a thin-wall steel cylinder hollow tower column construction method which comprises the following steps: mounting an inner support device in a steel cylinder, integrally hoisting the steel cylinder and the inner support device to a preset position in a to-be-constructed tower column section, and taking the steel cylinder as an inner mold for construction of an inner thin-wall steel cylinder hollow tower column; and the outer formwork is climbed in place through the pull-rod-free climbing formwork system, concrete is poured between the steel cylinder and the outer formwork formwork after formwork assembly, and tower body concrete pouring construction of the to-be-constructed tower column section is conducted. According to the construction method of the thin-wall steel cylinder hollow tower column, the inner mold does not need to be disassembled when the inner thin-wall steel cylinder hollow tower column is constructed, construction is more convenient, and potential safety hazards can be reduced.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for a thin-walled steel cylindrical hollow tower. Background technique [0002] At present, hollow towers usually use the traditional inner mold construction method to achieve the design requirements of the hollow inner chamber of the tower. After the concrete construction is completed, the molds are directly removed. The inner mold of the tower column is usually formed by connecting multiple formwork units in sequence. During construction, it is necessary to install the formwork units on the top of the tower column one by one, and then connect the inner and outer molds through the tie rods of the hydraulic climbing formwork system. , it takes a lot of time to install the formwork and adjust the position and elevation of the formwork, which reduces the construction efficiency of the hollow tower. In addition, when the traditional inner mold...

[0002] At present, the hollow tower column usually uses the traditional internal mold construction method to realize the design requirements of the hollow inner chamber of the tower column. After the concrete construction is completed, the formwork is directly removed. It takes a certain amount of time to remove the inner formwork, and the existing technology hollow The inner mold of the tower column is usually formed by connecting multiple formwork units in sequence. During construction, the formwork units need to be installed one by one on the top of the tower column, and then the inner mold and the outer mold are connected through the tie rods of the hydraulic climbing formwork system. , it takes a lot of time to install the formwork and adjust the position and elevation of the formwork, resulting in a decrease in the construction efficiency of the hollow tower

In addition, when the traditional internal formwork is used to construct the hollow tower column, the installation and disassembly of the internal formwork are all high-altitude operations. In actual operation, due to the limited width of the top structure of each section of the tower body, it is impossible to ensure sufficient supply for the installation and disassembly of the internal formwork. The operation area will affect the smooth progress of the hollow tower column construction, reduce the construction efficiency of the hollow tower column, and the high-altitude installation and disassembly of the inner mold will pose a safety hazard
