A connecting rod 45 is horizontally inserted between the connecting plate 43 and the connecting block 44.

[0021] like Figure 1 , Figure 3 As shown, the corner plate 2 is arranged at a right angle and is located between two adjacent template pieces 1. Multiple layers of reinforcing plates 21 are horizontally and spaced apart on the corner plate 2 to increase the structural strength and stability of the corner plate 2.

[0022] like Figure 3 As shown, multiple layers of positioning rods 11 are horizontally and spaced apart on both sides of the template piece 1, and end caps 12 are provided on the end faces of the positioning rods 11. An L-shaped positioning hole 22 is provided on the corner plate 2. The horizontal section of the positioning hole 22 is for the end cap 12 to pass through, and the vertical section is for the positioning rod 11 to slide into. Insert rods 23 are provided at both the upper and lower ends of the corner plate 2, and the insert rods 23 are threadedly connected to the template piece 1.

[0023] like Figure 1 , Figure 4 , Figure 5 As shown, the column clamp 3 is rectangular and tightens around the template piece 1 to reinforce and fix it. The column clamp 3 includes a fixed rod 31, a movable rod 32, a pair of side rods 33, a sliding sleeve 34, and a locking mechanism 5. The fixed rod 31 and the movable rod 32 are arranged parallel to each other, and the pair of side rods 33 are arranged parallel to each other between the fixed rod 31 and the movable rod 32.

[0024] like Figure 4 , Figure 5 As shown, one end of the side rod 33 is horizontally slidably connected to the fixed rod 31. A double-acting lead screw 35 is horizontally rotatably connected inside the fixed rod 31, and the double-acting lead screw 35 is threadedly connected to the side rod 33. The sliding sleeve 34 is horizontally slidably connected to the movable rod 32 and is sleeved on the side rod 33.

[0025] like Figure 4 , Figure 5 As shown, the locking mechanism 5 is used to fix the sliding sleeve 34. The locking mechanism 5 includes a locking plate 51, a locking pin 52, and a locking tooth 53.

[0026] like Figure 4 , Figure 5 As shown, the locking plate 51 is vertically slidably connected to the inner wall of the sliding sleeve 34, and the locking pin 52 is vertically threaded into the sliding sleeve 34 and rotatably connected to the locking plate 51. The locking teeth 53 are provided on the locking plate 51 and the side rod 33, and are inclined in opposite directions and interlock with each other.

[0027] like Figure 4 , Figure 5 As shown, a pair of diagonal braces 6 are rotatably connected to the middle of the side rod 33, and a tension plate 61 is rotatably connected to the end of the diagonal brace 6. A locking pin 62 is provided on the tension plate 61, and a row of locking holes 63 for the locking pin 62 to be screwed into is provided on both the fixed rod 31 and the movable rod 32.

[0028] When pouring concrete into a column, place two adjacent template pieces 1 vertically on the ground at right angles. Then, remove the corner plate 2 and place it against the connection point of the template piece 1. At this point, the positioning rod 11 and the end cap 12 pass through the positioning hole 22 on the corner plate 2. Then, control the corner plate 2 to slide vertically, causing the positioning rod 11 to slide along the positioning hole 22, and the end cap 12 to press against the surface of the corner plate 2. Finally, tighten the insertion rod 23 to insert it into the template piece 1, thus fixing the template piece 1 to the corner plate 2. Repeat this process to combine and fix the four template pieces 1.

[0029] Then remove the column clamp 3, and then remove the movable rod 32 and the sliding sleeve 34 from the side rod 33, and make the fixed rod 31 fit against the template piece 1, while the pair of side rods 33 are located on both sides of the template piece 1. Then control the bidirectional lead screw 35 to rotate, so that the bidirectional lead screw 35 controls the pair of side rods 33 to move closer to each other, so that the side rods 33 fit against the outer surface of the template piece 1.

[0030] Next, remove the movable rod 32 and place the two sliding sleeves 34 on the side rod 33, and make the movable rod 32 abut against the template piece 1. Then, control the locking pin 52 to rotate, so that the locking pin 52 drives the locking plate 51 to slide outward. At this time, the locking plate 51 presses the side rod 33, and under the snapping action of the locking teeth 53, they are snapped together and fixed, thus completing the adjustment and fixing of the column hoop 3.

[0031] Finally, control the rotation of the diagonal brace 6 and make the tension plate 61 fit against the fixed rod 31 or the movable plate. Then tighten the locking nail 62 and insert it into the locking hole 63 to complete the fixation of the diagonal brace 6, thereby increasing the structural strength and load-bearing capacity of the column hoop 3 connection position and realizing the stable reinforcement of the template plate 1.

[0032] Next, remove the diagonal brace 4 and fix the mounting base 41 to the ground or structural floor slab. Then, control the telescopic diagonal brace 42 to flip and rotate, thereby adjusting its length. Then, the connecting plate 43 on the telescopic diagonal brace 42 clamps the connecting block 44 on the template piece 1. Finally, insert the connecting rod 45 to fix the upper end of the telescopic diagonal brace 42, completing the installation of the diagonal brace 4.

[0033] Therefore, by setting adjustable column hoops 3, it can be adapted to the construction of concrete columns of different sizes and specifications, improving the practicality of the aluminum formwork device. At the same time, the column hoops 3 are fixed by tie-ins, increasing the structural strength and support strength of the column hoops 3, avoiding grout leakage, and ensuring the stable construction of concrete columns.
