Daily maintenance and inspection of scaffolding is crucial for ensuring its safe and stable operation, enabling timely detection of potential hazards and prevention of accidents.
First, the frequency of daily scaffolding inspections:
1. Daily inspection: Conducted by the site safety officer or scaffolding team leader, focusing on the working level and the area used that day, checking for immediate issues such as tilted uprights, loose scaffold boards, and damaged safety facilities.
2. Weekly inspection: Organized by the project’s technical manager, covering the entire scaffolding structure, including wall ties, support systems, and load conditions, and identifying potential risks in conjunction with the weekly construction plan.
3. Specialized inspection: After severe weather such as heavy rain, strong winds (level 6 or above), or blizzards, or after modifications to the scaffolding (such as adding members or adjusting height), or after one month of use, a comprehensive specialized inspection is required to confirm structural stability.
4. Regular Comprehensive Inspection: Monthly inspections will be conducted by the project manager, in conjunction with the supervisor and construction team, checking each item against the specific construction plan, creating written records, and archiving them.
Second, Specific Inspection Contents for Scaffolding
(1) Foundation and Support Structure
• Check for water accumulation and settlement in the foundation. If water accumulation is found, drain it promptly. If the settlement exceeds 10mm, reinforcement is required (e.g., adding base plates, compacting the base layer).
* Check for loose or displaced base plates and wooden base plates. Check for rotten wooden base plates and rusted or deformed steel pipe bases, ensuring tight contact with the ground.
• Check for secure connections between the cantilever beams of cantilever scaffolding and the guide rails of attached lifting scaffolding and the wall. Check for loose embedded parts or concrete cracks.
(2) Scaffold Structure
• Uprights and Horizontal Bars: Check if the uprights are vertical (vertical deviation should be ≤1/200 of the scaffold height), and whether they are bent or deformed; check if the horizontal bars are level, and whether the fasteners are tight (check torque with a wrench; the tightening torque of the fastener bolts should be 40-65 N·m), and whether there is any stripping or breakage.
• Wall Ties: Check if the connection to the wall is secure (it is strictly forbidden to use iron wire or electrical wire to replace the special connectors), whether the quantity meets the requirements of the plan (generally, at least one wall tie per 50-60㎡ of scaffolding), and whether any have been removed or loosened.
• Scissor Bracing and Diagonal Bracing: Check if they are installed according to the plan (scaffolding exceeding 24m in height should be continuously equipped with scissor bracing at an angle of 45°-60°), whether the connections of the members are secure, and whether there are any missing or deformed members.
• Working Level: Are the scaffold boards fully laid and securely fixed (protruding boards, i.e., exceeding 15cm beyond the horizontal bars, are strictly prohibited)? Are there any gaps at the joints? Are the toe boards (height ≥ 18cm) and guardrails (upper guardrail 1.2m high, middle guardrail centered) complete? Is the safety net tightly installed and undamaged?
(3) Safety Protection Facilities
• Check if the entrance and exit protective canopies are secure, and if there are guardrails on both sides of the passageway; is the safety net below the working level properly installed, without damage or omissions?
• Are the gaps between the scaffold and the building sealed with scaffold boards or safety nets to prevent people from falling or objects from falling?
(4) Load and Usage
• Check for overloading (uniformly distributed load on the scaffold generally does not exceed 2kN/m², concentrated load does not exceed 1kN). Is the material stacked evenly, and is it strictly prohibited to place heavy equipment (such as welding machines) on the working level for extended periods?
• Cutting, welding, and other open-flame operations are prohibited on scaffolding. If such operations are necessary, fire extinguishers must be available, and surrounding flammable materials must be cleared to prevent ignition of scaffolding materials (especially bamboo and wooden scaffolding).
Third, Daily Maintenance Measures for Scaffolding
1. Material Maintenance:
• Regularly remove rust and paint steel pipes, couplers, and scaffold boards (apply anti-rust paint and topcoat to steel pipes, and oil couplers after cleaning) to prevent corrosion.
• Aluminum alloy scaffolding should avoid contact with corrosive substances and should be stored without being squeezed or deformed.
2. Component Repair and Replacement:
• Replace any broken couplers or stripped bolts immediately; scrap any uprights or horizontal bars whose bending deformation exceeds the allowable value.
• Replace any cracked, broken, or rotten scaffold boards immediately; repair or replace any damaged safety nets promptly, ensuring they are free of holes and looseness.
3. Environmental Maintenance:
• Regularly remove construction waste and debris from the scaffolding to prevent increased load or falling debris that could cause injury.
• Ensure proper drainage around the foundation to prevent rainwater from soaking the ground and causing settlement.
4. Storage Management:
• Store unused components in a categorized manner. Steel pipes and uprights should be placed vertically to prevent deformation under pressure. Fasteners should be placed in dedicated containers to prevent loss or corrosion.
• When storing outdoors, cover with a rainproof tarpaulin to prevent wind and rain damage.
