The transmission tower is an important electric energy transmission device and is widely applied in the world. The transmission tower is in service in the open air for a long time and bears various strong load effects and severe environment effects. The coastal region in the south of China is a strong typhoon region, and wind-induced collapse accidents of transmission towers occur frequently throughout the year, so that serious loss and secondary disasters are caused. Therefore, it is necessary to develop and apply disaster-resistant reinforcement technology for transmission towers.
The existing transmission tower mostly adopts angle steel as a main material, and the angle steel is connected through bolts. To the wind-resistant reinforcement problem of transmission tower, the relevant research at home and abroad at present has provided some reinforcing apparatus of different grade type, and these reinforcing apparatus mainly fall into two main categories: drilling reinforcement and clamp type reinforcement. The wind-resistant reinforcing device of the early transmission tower mainly adopts a drilling reinforcing mode, and the wind-resistant reinforcement of the structure is realized by drilling holes on an original tower rod piece and installing a reinforcing material. The reinforcing method needs a large amount of overhead operation and is complex in field operation, and meanwhile, the original rod piece is damaged to a certain extent by drilling holes in the original rod piece, and the reinforcing method belongs to a destructive reinforcing method.
In recent years, some clamp type tower reinforcing devices have been developed, in which a clamp is disposed on a reinforcing member, and the reinforcing member is connected to an original tower rod member through the clamp, and a bearing force is transmitted by an extrusion force and a friction force in the clamp, thereby realizing reinforcement.
