Embodiment 1
[0038] Embodiment 1: The present invention provides a column-column connection node for the assembly connection between columns and columns when prefabricated parts are assembled, such as Figure 1-3 As shown, the connection node includes a symmetrical upper column 1 and a lower column 2, the upper column and the lower column are both part of the prefabricated assembly, and the assembly connection of the prefabricated assembly is realized by the butt joint of the upper and lower columns.
[0039] Among them, the upper column 1 is as figure 1 As shown in the figure, including a concrete cylinder, an upper convex column 3 and an upper groove 4 are preset on the lower side of the concrete cylinder, and the shape of the upper convex column and the upper groove can be changed, and the specific shape thereof Affecting the use connection of the present invention, in this embodiment, a square structure is used as an example for description. The structural strength and manufacturing di...
Embodiment 2
[0064] Example 2: The cross-section of the butted segment columns in the prefabricated concrete frame column-column connection node is square, the convex column and the groove are located in the center of the square, and the convex column and the groove are the center, and the longitudinal bars are evenly arranged in the The segment column section is located near the edge.
[0065] The number of the longitudinal bars is 12, four longitudinal bars are arranged on each side of the square section column section, and four longitudinally penetrating connection holes are arranged on the steel structure connector that is matched with the longitudinal bars. The structural connectors are symmetrically installed on the front and rear sides of the butted segment columns.
[0066] After the butt joint of the segment column, the two longitudinal bars on the side that are not connected and fixed by the steel structure connector are fixedly connected by the U-shaped connector.

Embodiment 3
[0069] Example 3: The overall size of the prefabricated concrete frame is large, and large-scale hoisting machinery needs to be used for construction in the docking assembly. The large-scale machinery has limited vision accuracy. Therefore, during the docking process, it is necessary to manually perform auxiliary docking near the section column, but the concrete section needs to be connected manually. The structure of the column is cumbersome, and it is difficult to push and assist only by manual force, and the suspended section column is easy to shake, and a slight accidental bump will cause a major safety accident and affect the construction of the project.
[0070] In order to avoid the above situation, improve the accuracy of segment-column docking, and reduce the difficulty of segment-column docking, the present invention further provides a docking auxiliary frame matching the column-column connection node direction of the prefabricated concrete frame.
[0071] The docking...
