Daily scaffolding protection is a key component of ensuring construction safety. It requires multiple approaches, including working-level protection, structural stability, fall prevention, impact protection, and environmental adaptation. Specific measures are as follows:
First, Basic Working-Level Protection
Scaffolding Board Protection:
1. Scaffolding boards must be fully laid, securely, and firmly in place. No protruding boards (i.e., any portion extending more than 15cm beyond the edge of the support point) are permitted. Joints must be securely fastened.
2. When using wooden scaffolding boards, they must be at least 5cm thick and secured to the crossbars with galvanized wire at both ends. Steel scaffolding boards must have anti-slip measures (such as anti-slip patterns) and be securely fastened to the crossbars.
3. Gaps between the working-level scaffolding boards and the building (such as balconies and edges) must be sealed with scaffolding boards or safety nets to prevent people or materials from falling.
Guardrails and Toeboards:
1. A 1.2m high guardrail must be installed on the outside of the working deck (the upper railing should be 1.2m above the ground, and the middle railing should be centered). The railing material must match the scaffolding structure (e.g., steel pipe) and be securely fastened.
2. An 18cm high toeboard (made of wood, steel, or sheet metal) must be installed below the guardrail to prevent materials from rolling down or people from protruding their feet.
3. A dense safety net (mesh density ≥ 2000 mesh/100cm²) must be hung on the outside of the guardrails and toeboards. The net must be taut and securely tied, with no damage or holes.
Second, Structural Stability Protection
Wall Tie Maintenance
1. Regularly inspect wall ties (the components connecting the scaffolding to the main structure) for looseness, deformation, or detachment, and ensure their quantity and location meet the design requirements (e.g., two steps, three spans). 2. Arbitrary removal of wall ties is prohibited. If temporary removal is necessary for construction, temporary supports must be installed and promptly restored. The number of removed ties must not exceed 1/3 of the total.
Scissor Braces and Horizontal Diagonal Braces
1. Check that the scaffolding braces (diagonal braces installed longitudinally along the outside of the scaffolding) are continuous and secure. The angle should be between 45° and 60°, and the base must be firmly rooted.
2. Scaffolding over 24m in height or in areas with poor lateral rigidity must be equipped with horizontal diagonal braces to ensure overall stability and prevent lateral overturning.
Vertical and Horizontal Bar Protection
1. The base or pad at the bottom of the vertical bar must be stable and free of settlement. The vertical deviation of the vertical bar must not exceed 1/200 of the height (e.g., a 10m high vertical bar should have a deviation of ≤5cm).
2. Horizontal bars (large and small) must be tightly connected to the vertical bars. The fastener tightening torque should be between 40 and 65 N·m to prevent loosening or deformation caused by overtightening.
Third, Fall Prevention and Personal Protection
Guidelines and Entrance and Exit Protection
1. Scaffolding access routes (such as ramps and ladders) must be equipped with handrails and anti-slip strips (spaced 30cm apart), with a slope no greater than 1:3. Platforms must be equipped with toeboards and safety nets.
2. Scaffolding at building entrances and exits must be protected by a protective shed. The roof should be constructed with double-layered scaffolding boards (spaced ≥ 50cm apart) or anti-smash steel plates, extending 1m in width on either side of the entrance and exit and ≥ 3m in length to prevent injury from falling objects.
Worker Protection
1. Operators must wear a safety helmet, a safety belt (high-hang, low-use, meaning the safety belt hook should be above the work area), and non-slip shoes. Hard-soled shoes and barefoot work are prohibited.
2. Playing, chasing, or working under the influence on the scaffold is strictly prohibited. Do not cross the railings or stay on non-working floors while working.
Fourth, Object Impact Protection and Material Management
Material Stacking Restrictions
1. Materials on scaffolding must be stacked evenly and must not be overloaded (construction loads are generally ≤ 2 kN/m²). Heavy materials such as rebar and formwork must not be stacked together.
2. Tools and accessories (such as fasteners and bolts) must be placed in tool bags and must not be thrown around. Waste materials must be promptly cleared to avoid accumulation.
Vertical Protection
1. When working on multiple floors, an isolation layer (such as a safety net) must be installed between the upper and lower floors to prevent falling materials from injuring personnel below.
2. The safety net on the outside of the scaffolding must be inspected regularly. Any damage or holes must be repaired or replaced immediately to ensure a tight seal.
Fifth, Environmental Acclimation and Regular Inspections
Adverse Weather Protection
1. In the event of winds of force 6 or above, heavy rain, snow, or dense fog, scaffolding operations must be stopped. The base of the uprights must be checked for water accumulation, and wall connections must be checked for looseness. If necessary, some uprights must be reinforced or removed. 2. Before resuming work after rain or snow, it is necessary to clean the ice and snow on the scaffolding and lay anti-slip mats to ensure that there is no risk of slipping on the working surface.
