Through the arrangement of the steel bars 2 along the extension direction of the column body and the design of the two end reserved slots 11, the reliable anchoring of the column body and the floor slab is ensured, and the overall structural stability is improved; the combined structure of the inner connecting plates 4 and the outer connecting plates 3 replaces the traditional welding / pouring process, simplifies the prefabrication process, and reduces the complexity of on-site installation; the modularized quick assembly is realized through the screw 31 connection, the dependence on heavy machinery is reduced, and the construction period is significantly shortened. The prefabricated construction column 1 is suitable for various different requirements. The embodiment 1 of the present application has four steel bars 2, and the connection mode is as shown in Figure 2 The embodiment 2 of the present application has eight steel bars 2, and the connection mode is as shown in Figure 3 .

[0029] Specifically, as shown in Figure 4 and Figure 5 , the inner side of the outer connecting plate 3 has an arc-shaped groove 32, the arc-shaped groove 32 is matched with the outer wall of the steel bar 2, the steel bar 2 is arranged in the groove 32 to realize positioning.
