Embodiment Construction
[0044] Examples see Figure 1-6 As shown, a bending-shear separated prefabricated frame column includes a group of precast concrete column sections spliced up and down. The column sections include an upper column section 1 and a lower column section 2. 3 at the bending moment inversion point between the layers and the middle of the column section.
[0045] The bottom end surface of the column section is pre-embedded with a horizontal bottom steel sealing plate 4, and the center of the bottom steel sealing plate 4 coincides with the center of the cross section of the column section. The lower convex shear key 5. The shear key 5 and the bottom steel seal plate 3 are integrally machined and formed, and the shear key 5 is centrally symmetrically arranged on the bottom steel seal plate 3, and is a bump and a convex line located in the center of the bottom steel seal plate Or a combination of both. In this embodiment, it is a bump arranged in the center.
[0046] The top surface...
