[0023] Furthermore, the L-shaped steel plate 1 is welded from two pieces of Q235 steel. The L-shaped steel plate 1 and the trapezoidal clamp 7 must be manufactured accurately, with a verticality error not exceeding 5 mm. Q235 steel is a common material on site, saving manufacturing costs.

[0024] Furthermore, a square timber 2 is provided inside the L-shaped steel plate 1 , and the square timber 2 is in contact with the L-shaped steel plate 1 . By tightening the double nut 9 , the tension screw 3 can fix the L-shaped steel plate 1 and the square timber 2 in contact with each other.

The L-shaped steel plate 1 is fixed against the square timber 2, so that the square timber 2 and the template 4 can be fixed against each other, thereby effectively reinforcing the structural column 5 at the positive corner of the masonry wall 8.

[0026] It is particularly disclosed that a hole 6 is opened in the middle of the trapezoidal clamp 7, and the tension screw 3 is inserted into the hole 6. The trapezoidal clamp 7 can move on the tension screw 3. The tension screw 3 is placed 0.6m away from the concrete ground surface, and the second one is evenly arranged 1.5m away from the first one.

[0030] Working principle: First, install the template 4 on the positive corner of the masonry wall 8, then install the square timber 2 on the outside of the template 4, and then install the L-shaped steel plate 1 on the outside of the square timber 2. At the same time, pass the tension screw 3 through the template 4 to the negative corner of the masonry wall 8, sleeve the trapezoidal clip 7 on the tension screw 3, and then thread the double nut 9 on the tension screw 3. Turn the double nut 9 to make the trapezoidal clip 7 move forward and abut against the inner side of the masonry wall 8 until the double nut 9 is tightened.
