Scaffold erection must be coordinated with the construction progress, and the erection height shall not exceed two steps above the adjacent wall. Scaffolding after each step, should be in accordance with the provisions, correct the interval, longitudinal distance, the verticality of the crossbar and stud.

1. Scaffolding pile bottom must be laid in a straight line, and the vertical pole position should be aligned as required. The foundation shall be compacted with 3: 7 lime soil, with wooden boards with a length of not less than two spans and a thickness of not less than 5cm, and a drainage ditch shall be set outside the shelf to maintain good drainage performance. Scaffolding must be provided with vertical and horizontal sweeping poles. The vertical sweeping pole should be fixed on the vertical pole with right-angle fasteners, and the distance from the basic epithelium should not exceed 200 mm. The horizontal sweeping bar should be fixed on the vertical bar near the bottom of the vertical sweeping bar with right-angle fasteners. When the vertical rod foundation is not at the same height, the vertical sweeping rod at the high place must extend two spans to the low place and be fixed with the vertical rod, and the height difference is not greater than1m. The shelf plane is arranged along the outer contour line of the building.

2. It is strictly forbidden to mix steel pipes with outer diameters of 48mm and 565,438+0 mm for vertical poles. Lippi pole of the vertical pole is 50cm away from the sheath, and the sheath pole is 1.7 ~ 2.0m away from the sheath. The connectors of vertical rods should be staggered and arranged at different intervals. When erecting a pole, a throw brace shall be set every 6 spans. After the wall piece is installed stably, the throw brace shall be removed according to the situation. The top of the vertical pole is higher than the parapet epithelium 1m and the cornice epithelium1.5m..

3. Frame and structure are rigidly connected, the horizontal distance is not more than 6m, and the vertical distance is not more than 4m. Starting from the first step of the bottom longitudinal horizontal bar, the layers are rigidly connected. The tie rods or diagonal braces of wall parts should be set horizontally, and upward inclined connection is strictly prohibited. Scissoring is 10 step by step, 5 steps by step, and there must be vertical poles at the intersection. The number of vertical poles in each group is odd, and even numbers are not allowed.

4. The main rail, that is, the longitudinal horizontal bar, is arranged on the inner side of the vertical bar and fastened with cross fasteners, and no omission is allowed. The joint positions of the upper and lower rails shall be staggered within different vertical distances of the vertical rods. The staggered distance between two adjacent joints in the horizontal direction shall not be less than 500mm, and the distance from the center of each joint to the nearest master node shall not be greater than 1/3 of the vertical distance. This project adopts wooden scaffolding, and the longitudinal horizontal pole is used as the bearing of the transverse horizontal pole. The horizontal deviation of the same row of main rails is not more than one thousandth of the total length after the rails are connected.

5. The putlog, that is, the horizontal pole, should be arranged close to the vertical pole, and then it is forbidden to dismantle it with right-angle fasteners. The center distance between the two right-angle fasteners at the main node should not be greater than 150mm, the protruding length of one end against the wall should not be greater than 500mm, and the distance from the decorative surface of the wall should not be greater than100 mm. ..

6. Scaffolding: it must be laid well and tightly, away from the wall 120~ 150mm, and there can be no springboard. Scaffolding probe shall be fixed on the support rod with 3.2mm galvanized lead wire. Scaffolding at corners and ramps shall be reliably connected with horizontal bars to prevent sliding. Scaffolding operation layer must be provided with two guardrails and baseboards, with the upper railing height of 1.2m, the middle railing set in the middle, and the baseboard height of 180mm.
