In the super-high scaffolding, the foundation should be flat and solid, the base and the pad should be set, and reliable drainage measures should be taken to prevent the water from immersing the foundation. According to the setting condition of the wall bar and the load size, the commonly used open double-row scaffolding poles are generally 1.05~1.55m horizontally, and the masonry scaffolding step is generally 1.20~1.35m. The scaffolding for decoration or masonry and decoration is generally It is 1.80m and the vertical length of the pole is 1.2~2.0m. It allows the height of the erection to be 34~50m. When set for a single row, the vertical distance of the pole is 1.2~1.4 m, the longitudinal length of the pole is 1.5~2.0m, and the height of the erection is 24m.
The vertical horizontal rod of the super-high scaffolding should be arranged on the inner side of the pole, and its length should not be less than 3 spans. The vertical horizontal rod can be used as a butt joint fastener, and can also be overlapped. If the butt fastener method is adopted, the butt fasteners shall be staggered; if the lap joint is used, the lap length shall not be less than 1 m, and three rotating fasteners shall be fixed at equal intervals.
A horizontal horizontal rod must be installed at the main node of the super-high scaffold to be fastened with a right angle fastener and it is strictly forbidden to remove. The center distance of the two right angle fasteners at the main node should not be greater than 150 mm. In the double-row scaffolding, the outer horizontal extension of the horizontal horizontal rod against the end of the wall shall not be greater than 0.4 times the horizontal distance of the vertical pole, and shall not be greater than 500 mm; the horizontal horizontal rod at the non-main node on the working layer shall be based on the supporting scaffold Need to be equally spaced, the maximum spacing should not be greater than 1/2 of the longitudinal distance.
Super-high scaffolding must be provided with vertical and horizontal sweeping rods. The longitudinal sweeping rod should be fixed with a right angle fastener on a pole that is no more than 200mm from the base of the base. The horizontal sweeping rod should also be fastened to the pole below the longitudinal sweeping bar with right angle fasteners. When the foundation of the pole is not at the same height, the longitudinal sweeping rod at the height must be extended to the lower part to fix the two spans to the pole, and the height difference should not be greater than lm. The distance from the axis of the pole above the slope to the slope should not be less than 500mm.www.eg-scaffold.com
