Non-dismantling formwork column

The invention discloses a non-dismantling formwork column which comprises a combined formwork (100), a shaped reinforcement cage (200) and a detachable opposite-pulling piece (300), and is characterized in that a combined formwork shell (100) is formed by combining a cover plate (1) and a side plate (2) of a pre-embedded light cushion block (20) through an L-shaped connecting strip (3) and a structural adhesive (4); the cover plate (1) and the side plates (2) are fiber-reinforced high-performance cement-based prefabricated plates, the outer side faces (5) of the fiber-reinforced high-performance cement-based prefabricated plates are smooth surfaces, and the inner side faces (6) of the fiber-reinforced high-performance cement-based prefabricated plates are rough surfaces with outwards-extending steel fibers (7) and grooves (8). Positioning pipes (9) are arranged on the shaped reinforcement cage (200) in the orthogonal direction of the cross section, and the positions of the positioning pipes (9) are in one-to-
