[0038] Locking device, see Figure 3 , multiple non-dismantling prefabricated formworks 1 are locked, including transverse main reinforcing ribs 41 and first tension bolts 51. The transverse main reinforcing ribs 41 are arranged on each side of the non-dismantling concrete formwork, close to the rear sealing formwork 3; the first tension bolts 51 pass through the middle of the non-dismantling concrete formwork, and pass through the rear sealing formwork 3 and the transverse main reinforcing ribs 41 in turn, locking the two opposite transverse main reinforcing ribs 41 and pressing the non-dismantling prefabricated formwork 1. The tension bolts resist the transverse horizontal force generated when pouring concrete. Among them, the transverse main reinforcing ribs 41 are reinforced wood beams or steel.
[0039] The locking device includes four transverse main reinforcing ribs 41 and two first tension bolts 51 .

According to the characteristics that most of the columns are square or rectangular, several standard formwork blocks (each corner is a module) are divided along the perimeter of the column to enclose the column to form a prefabricated formwork. Since the cross-sections of the columns are different in size and there are many types, there will be gaps between the standard modules, which are blocked by on-site supplementary tool formwork (rear sealing formwork 3), and the tension screw is used to prevent the formwork from expanding when pouring concrete. After the poured concrete reaches a certain strength, the tool formwork is removed to form it.
