In the design, it is not allowed to use steel bars to weld the anchor bolts and the steel cage together. But for the pipe gallery, this has no effect on future use. For large-scale tower crane foundation construction, it is not allowed to use steel bars to weld anchor bolts and steel cages together. Because the anchor bolts have undergone strict heat treatment to achieve a certain performance, the performance of the material after welding may change and the design performance may not be reached. , In addition, there must be stress after welding, which will make the bolts easy to break. If it is welding, it will be dangerous to pull the weld seam apart. The tower crane often falls down, so please follow the specifications. The bottom of the anchor bolt is hook type. To ensure accuracy, it should be measured when pre-embedded. When vibrating, pay attention to fixing it with a brace. Retest after vibrating. Generally, there is no problem.
