The thickness of the inner and outer walls of civil air defense basements is often different from that of ordinary basements, and in addition, the thickness of the inner and outer walls of the above-ground structure is also different. Therefore, there are at least 6 kinds of reinforced concrete shear walls with different thicknesses in a reinforced concrete structure, and at least 6 kinds of width steel bar ladder bars need to be welded for the support of the steel bar mesh on both sides of the wall surface. Welding steel bar ladder bars is an important task in the construction process of reinforced concrete structures. It is necessary to ensure firmness and be able to complete quickly. In view of the above situation, using traditional ladder bar welding frames requires 6 ladder bar welding frames with different widths, which will cause problems such as multiple processing, material waste, man-hour waste, and more site occupation.
