Positioning at a fixed distance, laying out the position of the cantilever beam, and marking it properly.
The cantilever beam must ensure sufficient anchorage strength and section buckling resistance, and the cantilever length should be determined according to the design.
When the ordinary main beam is suspended, the vertical pole is directly supported on the suspended beam, and the longitudinal spacing of the horizontal suspended beam is the same as the longitudinal spacing of the upper scaffold vertical pole; There should be reliable positioning connection measures between the upper scaffold uprights and the cantilever beam support structure to ensure the stability of the upper scaffold body.
Usually, steel pipes with an outer diameter of 150-200mm and an outer diameter of Φ 40mm or steel bars with an outer diameter of Φ 25mm are welded on the cantilever beams or longitudinal connecting beams, and the upright tube is sleeved on it.
At the same time, a sweeping rod is set at the lower part of the upright tube.
