Angle steel component will produce deformation or damage in different degrees during service due to external load and other factors, and the whole tower is time-consuming and laborious to demolish and reconstruct, so it is a relatively ideal method to adopt a reasonable reinforcing method. At present, scholars at home and abroad have carried out relevant research on angle steel reinforcement, and put forward different reinforcing methods and carried out true type test verification, such as T type reinforcement, cross type reinforcement, square type reinforcement and FRP new material reinforcement, but these reinforcing methods change the shape of angle steel greatly, and the hoop form is complex, and it is difficult to implement when reinforcing the angle steel located in the upper part of the transmission tower. The existing L type reinforcement with small change of original shape of angle steel mainly includes welding type and hoop type, and still has the above-mentioned inconvenience problem, which is difficult to process on site.

[0007] Further, one clamping plate is matched with a plurality of clamping pieces, the clamping pieces are L-shaped, and the two ends of the clamping pieces extend to the outer side of the angle steel.
