Description

Technical Field

[0001] The utility model relates to the field of assembled columns, in particular to an assembled column docking structure. Background Art

[0002] Prefabricated columns refer to columns assembled from prefabricated components (i.e. structural components that are prefabricated in the factory) in structural projects such as buildings, bridges, and elevated roads. Compared with traditional on-site casting methods, prefabricated columns have the characteristics of improved efficiency, quality control, reduced environmental pollution, lower costs, and flexibility.

[0003] The current prefabricated columns widely adopt the sleeve grouting connection technology, which involves inserting the column reinforcement into the prefabricated sleeve and then pouring mortar to fix it. This method ensures the stability and reliability of the structure. However, it faces challenges in actual operation: the dense reinforcement inside the column requires grouting of a large number of sleeves one by one, resulting in low work efficiency. In addition, this process not only requires a large amount of grouting equipment support, but also increases manpower and time costs, becoming a significant burden in the implementation process. Therefore, a prefabricated column docking structure is proposed to solve the above problems. Utility Model Content
