Embodiment Construction
[0014] Such as figure 1 , 2 , 3, 4, a method for making concrete cylindrical formwork, including a corrugated pipe 1, a plurality of horizontal hoops 2 and a plurality of wooden vertical flutes 3, the corrugated pipe 1 is cut into two symmetrical pieces from the middle, so The horizontal hoop 2 includes an arc-shaped steel bar 1 4 and an arc-shaped steel bar 2 5. A plurality of movable sleeves 6 are sleeved on the arc-shaped steel bar 4, and both ends of the arc-shaped steel bar 4 are provided with threads. In section 7, nuts 8 are respectively sleeved on the threaded section 7, and welding sleeves 9 are respectively welded on the outer sides of the two ends of the arc-shaped steel bars 5. The two ends of the welding sleeve 9 have the same diameter, and the movable The two ends of the sleeve 6 have different diameters. The diameter of the thin end is smaller than the diameter of the nut 8, and the diameter of the thick end is larger than the diameter of the welding sleeve 9. The...
