Scaffolding is an indispensable temporary structure in construction. Its safety and stability are directly related to the safety of construction workers and the progress of the project. Mastering correct construction and use techniques is crucial to ensuring efficient and safe construction.
First, scaffolding construction must strictly adhere to design specifications. The foundation must be flat and solid, and pads should be laid as necessary to distribute the load and prevent settlement. The spacing between vertical posts must meet standards, typically no more than 1.5 meters horizontally and 2 meters vertically, and vertical deviation must be within the permitted range. Crossbars and diagonal braces should be arranged appropriately to form a stable triangular structure and enhance overall anti-overturning resistance.
Second, the use of fasteners is crucial. Fasteners must be tightened, with a torque control between 40 and 65 N·m to prevent loosening and structural instability. Scaffolding boards should be laid tightly, without probes, and their edges should be securely fastened to the support rods. For high-rise scaffolding, wall ties should be installed, typically every 3-4 steps, to ensure a secure connection to the building and prevent lateral movement.
During use, regular inspections are essential. Focus on checking the tightness of fasteners, deformation of rods, and foundation settlement. Any potential hazards should be rectified immediately. Stability should be reassessed after severe weather (such as strong winds or heavy rain). Guardrails and safety nets should be installed on the working floor, and personnel must wear safety belts. Stacking materials on the scaffolding is strictly prohibited to prevent overloading.
Finally, when dismantling the scaffolding, follow the principle of "dismantling from top to bottom, layer by layer." Simultaneous dismantling is strictly prohibited. Dismantled components should be sorted and stacked to prevent damage or loss.
Through scientific construction, standardized use, and rigorous maintenance, scaffolding can truly become a safety guarantee during construction, rather than a source of risk.
