Problems solved by technology

These two methods have their own advantages and disadvantages. The cast-in-place columns need to support the formwork, bind the internal steel bars first, and then pour the concrete. The process is more complicated, there are many wet operations, and the quality is not easy to guarantee.
Integral prefabricated columns also require relatively complicated processes in the prefabrication field (for example, "Prefabricated Reinforced Concrete Hollow Column Formwork and Its Manufacturing Method", CN103737718A), and need to be hoisted at the construction site, which requires high lifting equipment. At the same time, there are certain security risks

Embodiment Construction

[0012] The embodiments of the present invention are described in detail below: this embodiment is implemented under the premise of the technical solution of the present invention, and detailed implementation methods and processes are provided, but the protection scope of the present invention is not limited to the following embodiments.

[0013] First, according to the specific design scheme of the columns in the structure, determine the required height and section size of the columns. Then determine the number of modules that need to be divided, and also get the cross-sectional size of each module.

[0014] Prefabricate according to the determined module section size and height: first support the formwork, then fix the position of the required longitudinal reinforcement 1, then bind and fix the spiral reinforcement 2 on the outside of each longitudinal reinforcement 1, and then pour concrete 3. After the concrete 3 is hardened, the formwork is removed to form a column module....

Abstract

The invention provides a semi-prefabricated concrete column module and belongs to the technical field of buildings. The semi-prefabricated concrete column module is structurally composed of hollow concrete blocks, longitudinal reinforcing steel bars, spiral stirrups and carbon fiber cloth. The longitudinal reinforcing steel bars and the spiral stirrups are arranged in solid parts of the concrete blocks. The concrete blocks are connected through the carbon fiber cloth. The longitudinal reinforcing steel bars are arranged on the four edges of each block in the length direction of the hollow concrete block. Each spiral stirrup is spirally arranged on the outer side of the corresponding longitudinal reinforcing steel bars. In a construction field, all column modules only need to be vertically stacked together and are connected through pasting the carbon fiber cloth, the longitudinal reinforcing steel bars are inserted in the hollow parts, then the concrete is poured, and therefore a column can be formed.

Description

technical field [0001] The invention relates to a column structure in the construction field, in particular to a semi-prefabricated concrete column module. Background technique [0002] The column is one of the important components in the concrete structure, and it is the main anti-lateral force component of the structure. The internal forces it needs to bear are mainly bending moment, shear force and axial force. At present, there are mainly two types of concrete columns: one is cast-in-place, and the other is integral prefabrication. These two methods have their own advantages and disadvantages. The cast-in-place columns need to support the formwork and bind the internal steel bars first, and then pour the concrete. The process is more complicated, there are many wet operations, and the quality is not easy to guarantee. The integrally prefabricated columns also require relatively complex processes in the prefabrication field (for example, "Prefabricated Reinforced Concre...
