Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled concrete prefabricated component connection node. Background Art

[0002] Currently, building industrialization and standardization are gradually becoming important development directions in the construction industry. The quality of precast concrete column node connections has a significant impact on the safety and stability of the overall structure. In actual projects, traditional precast concrete column-column node connections mostly use wet connection methods such as sleeve grouting and grouting anchors. Sleeve grouting connections have problems such as unreliable sleeve connections and loose pressure grouting. They may also result in insufficient grouting strength and insufficient anchoring length. Furthermore, sleeve connections are prone to insufficient grouting pressure, resulting in localized wrapping of the steel bars, severe eccentricity, and stress concentration in the grouting material.
