Example Embodiment
[0021] Example 1: see Figure 1-4 , The prefabricated reinforced concrete structural column 2 for the prefabricated building of the present invention has a rectangular or square cross-section, and the longitudinal force in the concrete (including the connection node position with the beam) is made of the designed load-bearing steel bar 5 as the column reinforcement frame. Position (take the cross connecting beam as an example), the cross section of the inertial column extends out of the side steel joint 3 (connected to the column reinforcement), and the upper and lower structural steel bars of the connecting beam are located on the side of the inertial column and the diameter is larger than the beam One grade of structural steel reinforcement, connecting steel 4 with external thread, extending thread length 5cm, thread to the side of the column, cross connecting steel height difference, 1 steel diameter arrangement, connecting nodes do not leave concrete post-pouring section (fac...
Example Embodiment
[0024] Example 2: see Figure 5-16 , As in Example 1, the cross-sectional shape of the prefabricated reinforced concrete column 2 can be L-shaped ( Figure 5 ), T shape ( Image 6 ), cross ( Figure 7 ), a glyph ( Figure 8 ), at least one end of the longitudinal end face has an extended connecting steel joint 6 and an extended connecting column steel bar 5; the column and beam connection nodes, and each side of the connection has a shaped steel joint 3 extending out of the side of the column and a threaded connecting steel bar 4, this section The internal skeleton of the concrete column is still column steel 5, and no concrete post-cast section is left. Column and column connection see Figure 5-8 , Column and beam connection see Figure 9-16 ,among them Figure 13-16 Respectively, there are connected beam structures.
