For factory buildings and public buildings, the span of the outer scaffold is not more than 1.5 meters, the step distance of the scaffold body is not more than 1.8 meters, and in the structural construction process, the erection height of the scaffold body is required to exceed the height of an operation layer by more than 1.2 meters. At this time, for the wall connecting piece of the outer operation frame, the length of 3 spans in the horizontal direction is about 4.5 meters, and generally at the middle position of the column spacing, after the constructed outer frame is connected with the beam plate, the cantilever height of the outer frame is generally above 5.2 meters, and exceeds the height of 3.6 meters of the two steps of frames, but the structure under construction does not allow the outer frame to be connected with the template supporting frame, namely, the wall connecting piece has no reliable attachment point during the construction of the structure, so that the safety is ensured, the outer scaffold connecting structure is required to be designed, and the construction safety is ensured.
