What are the requirements for scaffolding?

The pad iron and base should be accurately placed on the positioning line, and the pad iron must be laid flat and not suspended. When installing columns, steel pipes with different outer diameters shall not be mixed, and the butt fasteners of adjacent columns shall not be within the same height, and the staggered distance shall meet the structural requirements. When the column is erected, a throwing brace should be set every 6 spans, which can be removed according to the situation until the wall part is installed stably. When reaching the structural layer with wall connecting pieces, the wall connecting pieces shall be set up immediately after the erection of columns, longitudinal horizontal bars and transverse horizontal bars. The synchronous longitudinal horizontal rod of closed scaffold must be wound around the circle and fixed with right-angle fasteners and yin-yang corner columns. The distance from one end of the horizontal pole of the double-row scaffold against the wall to the decorative surface of the wall should not be greater than100 mm. When the scaffold operation floor is two steps above the wall, temporary stability measures should be taken until the wall is erected. Scissors and cross braces should be erected synchronously with columns and vertical and horizontal rods, and the distance between the center line of fasteners such as scissors and cross braces and the main node should not be greater than 150 mm ... The opening of docking fasteners should be upward or inward. The length that the end of each bar extends out of the edge of the fastener cover plate should not be less than 100 mm, and the scaffold board should be paved fully and stably, and the distance from the wall should not be greater than150 mm. The probe of the scaffold board should be fixed on the support bar with galvanized steel wire with a diameter of 3.20mm, and the scaffold board at the corner and the chute flat mouth should be reliably connected with the horizontal bar for sliding. Railings and skirting boards shall be set inside the outer column, with the upper railing epithelial height of1.20m, the middle railing set in the middle, and the skirting board height of150mm. ..
