The requirements are as follows;
1. The width of the scaffolding ramp shall not be less than 1.5m, and the slope should be 1:6 (height:length). The width of the pedestrian ramp shall not be less than 1m, and the slope shall not be greater than 1:3.5.
2. The spacing between vertical poles and longitudinal horizontal poles should be compatible with the structural scaffolding. The spacing between vertical poles and longitudinal horizontal poles on a single ramp should not exceed 1.5m. The spacing between transverse horizontal poles shall not be greater than 1m. When the width of the ramp is greater than 2m, a suspender should be added in the middle of the transverse horizontal poles, and support rods and splayed fences should be added under every other vertical pole.
3. Scaffolding boards should be laid tightly and firmly. When overlapping, double transverse horizontal bars should be used at the end of the board. The end of the lap board should overlap the horizontal horizontal rod by 200mm, and use triangular wood to fill the convex edge of the board head. The scaffolding boards of the slopes should be nailed with anti-slip strips, the thickness of the anti-slip strips should be 30mm, and the spacing should not be greater than 300mm.
4. A platform should be set up at the turning point of the zigzag ramp. The area of ??the platform should be based on construction needs, but the width should not be less than 1.5m. The platform should be tied with scissor braces or figure eights.
5. The ramp and platform must be tied with two protective railings and a 180mm height foot guard.
