Therefore, positioning protection is required for positioning. Conventional positioning protection mechanisms for beams can only position the beams in a certain direction or at a certain height. It is difficult to adjust them in multiple directions or at different heights, which leads to unstable positioning of the beams in the construction project, thereby affecting the efficiency of the construction project.
