The processing of steel bar anchor rods includes welding a single or multiple steel bars together. In the existing construction technology, when the anchor bar reinforcement needs to be constructed in sections, welding is usually used for connection. This method requires welding the isolation frame and the main steel bar on site first. After the main steel bar and the isolation frame are welded, a section of the steel cage is placed in the hole and then the second section of the main bar is fully welded to the first section of the main bar. This construction method has complex welding work and a huge amount of welding, which makes the construction speed slow, seriously affecting the construction progress. Utility Model Content
