[0042] Demonstration of the working process of the technical solution in this application:
[0043] See attached document Figure 4 The circular square tube beam (column diameter ≤ 1000mm) is processed according to the diameter of the column to be reinforced. The manufacturer performs the processing to achieve factory production. After the adjustable column template reinforcement device is processed, it is assembled on the outside of the column template according to the diameter of the column.
[0044] ①Reference Figure 2 As shown, two semi-circular 50×50×3.0mm circular square tube beams 1 are connected by a square tube beam connecting device 3;
[0045] ②Reference Figure 6 As shown, the square tube beam connecting device 3 includes an M18 bolt 3.1, an M18 connecting nut 3.2, and a 5mm connecting lug 3.3;
[0046] ③Reference Figure 5 As shown, the adjustable support 2 includes an adjustable support 2.1, a 36mm screw 2.2, an adjusting nut 2.3, a 50mm long 48×3.0mm short steel pipe 2.4, and a 5mm steel plate shim 2.5;
[0047] ④Reference Figure 1 As shown, an 18mm circular wooden template 5 is wrapped around the side wall of the cylinder. After the circular wooden template 5 is installed, multiple 50×50×3.0 square tube back ribs 4 are vertically fixed to the outer side wall of the circular wooden template 5.
[0048] ⑤Reference Figure 4 As shown, the adjustable support 2 is assembled onto the circular square tube beam 1, and the extension length of the adjustable support 2 is adjusted to the shortest.
[0049] ⑥Reference Figure 3 As shown, the circular square tube beam 1 is connected to the cylinder through the square tube beam connecting device 3, and the assembled 50×50×3.0mm circular square tube beam 1 is moved to the design position.
[0050] ⑦ Connect the adjustable support 2 to the 50×50×3.0 square tube back rib 4 tightly by adjusting nut 2.3. Note that the two opposite surfaces work together to ensure that the extension length of each adjustable support 2 is consistent. Specifically, by rotating the adjusting nut 2.3 counterclockwise (usually by hammering with a small hammer), the adjusting nut 2.3 cannot move backward under the contact of the short steel tube 2.4, forcing the 36mm screw 2.2 to extend, so that the adjustable support 2.1 is tightened against the square tube back rib 4;

The technical solution of this application increases the strength and stability of the formwork reinforcement system, effectively avoiding problems such as bulging and bursting of the cylindrical formwork, ensuring the verticality of the cylindrical formwork, and achieving good safety and environmental friendliness. It enables standardized construction of the cylindrical formwork reinforcement system. By adjusting the adjustable support length, it can reinforce cylindrical formwork of different diameters within a certain range (cylinder diameter ≤ 1000mm). All components can be sourced locally on construction sites, making it easy to operate, highly practical, convenient to install and dismantle, and highly versatile.
