Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a device for manufacturing thin-walled hollow composite columns. Background Art

[0002] Prefabricated structures are increasingly being used. Columns are crucial components in these structures. However, existing prefabricated structures often use solid prefabricated columns, which results in heavy prefabricated components. Component connections require grouting sleeves, resulting in poor structural reliability. Numerous solutions have been proposed, with hollow columns being one of the most promising.

[0003] In the existing technology, the production of hollow columns is very complicated due to the particularly complex stirrups inside the columns. There are mainly the following solutions: 1. Using the centrifugal method, the hollow part of the component is circular and the wall thickness is thick, and the weight reduction effect of the component is poor. In addition, due to the centrifugal effect, the concrete is easy to segregate, and a layer of cement slurry is easy to form on the inner wall surface of the component, resulting in a decrease in the strength of the overlapping surface of the new and old concrete; 2. Using air bags as the inner mold for the complex internal stirrups, the air bags need to be assembled into small units. In order to be hollow, many air bags will be used. The placement and removal of the airbags requires a lot of manpower, resulting in extremely low construction efficiency and difficulty in industrialization. Third, the centrifugal method with the airbag inner mold has the same low construction efficiency as the second option, but also suffers from the disadvantages of the first option. Due to the centrifugal effect, the concrete is prone to segregation, and the outer wall of the column is also thick, resulting in poor weight reduction. Fourth, the method uses partially hollowed columns and buried corrugated steel pipes. This solution increases the waste of corrugated pipes, and since most of the concrete is still solid, the weight reduction effect is poor. The additional steps of burying and fixing the corrugated pipes make the construction process complex and inefficient, making it difficult to achieve industrial production. 5. Turn the column over on the formwork table and cast each side separately. Each time the prefabricated column is turned over, the component needs to reach a higher strength, the interval time is very long, the production efficiency is extremely low, and it is not conducive to industrialized production. Since the component rotates, the mold is fixed on one side, the component flipping efficiency is extremely low, and the manual process is difficult. 6. Use an integrated steel cage and wrap the finished plate (such as cement fiber board). This solution requires additional tie-fixing measures because there is no tie between the stirrups and the outer skin. The outer skin cannot participate in the overall force of the column and only serves as a template. The project cost is high and the material utilization rate is low.

[0004] Therefore, we proposed a thin-walled hollow composite column manufacturing equipment to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a thin-walled hollow composite column manufacturing device to solve the problems of high engineering cost and low material utilization rate in the thin-walled hollow composite column manufacturing process mentioned in the background art.
