Therefore, the burying of the anchor bolts is a The key link of steel structure construction, the embedding accuracy of anchor bolts directly affects the installation of upper steel components. It is difficult to control the size of the embedded setting of the anchor bolts, especially if the anchor bolts are suspended in the air, the accuracy control is even more difficult.

The traditional anchor bolt fixing method is generally the method of line alignment, theodolite alignment method, etc., that is, the anchor bolts are manually welded one by one with the main reinforcement of the foundation fixed on the top of the foundation cap, and then concrete is poured. The position deviation, elevation deviation and verticality cannot be guaranteed, and the anchor bolts cannot pass through the bottom plate of the steel column smoothly, so the column bottom plate has to be reamed, the anchor bolts are changed on site, and the anchor bolts are bent and other unconventional methods. The original mechanical properties of the anchor bolts are improved, and the labor cost is also increased.
