Daily inspections of erected scaffolding are crucial for ensuring its continued safety and stability. This requires a combination of regular inspections and special inspections, focusing on structural stability, component integrity, and protective effectiveness. Specific inspection content and methods are as follows:
First, the frequency and timing of inspections of erected scaffolding.
Regular inspections: A comprehensive inspection should be conducted at least once a week, under the responsibility of the project safety officer or scaffolding team leader.
Special inspections:
Immediate inspections are required after severe weather conditions such as heavy rain, strong winds (force 6 or higher), heavy snow, and earthquakes.
After a sudden increase in the load on the scaffolding (e.g., when materials are stacked together).
When abnormal conditions such as loose or deformed members are discovered.
After hot work such as welding or cutting on the working floor, fire prevention measures and member damage must be checked.
Second, Inspection Contents and Key Points for Erected Scaffolding
1. Foundation and Uprights: Ensure Stable Load-Bearing
Foundation: Check for water accumulation (needs prompt drainage), settlement (ground cracks, tilted pads), loose soil erosion, etc.
Base and Pads: Check for looseness, deformation of screws, displacement, or breakage of pads (including rotten wooden pads);
Uprights: Check for excessive verticality (deviation ≤ 1/200 of the pole height), bends, rust (rust depth ≤ 0.5mm), cracks, pole spacing consistent with the plan, and staggered joints (out of sync, different spans).
2. Crossbars and Connecting Components: Ensure Overall Rigidity
Large/Small Crossbars: Check for looseness or missing components. Check fasteners connecting to the vertical posts (torque wrench available, 40-65 N·m). Check that small crossbars are close to the vertical posts and securely fastened at both ends (extending 100mm or more).
Fasteners: Check for cracks, stripped threads, loose or missing bolts, and sufficient fasteners at overlapping joints (e.g., a scissor brace requires three rotating fasteners).
3. Scissor Braces and Horizontal Bracing: Enhance Anti-Sway Capacity
Check whether scissor braces are continuous (full height and length), maintain an angle between 45° and 60° with the ground, check for bent or corroded components, and ensure secure connections to the vertical posts/crossbars.
Check whether horizontal braces (for L-shaped and open-type scaffolding) are installed as required (at both ends and every six spans in between), and whether the connections are secure.
4. Wall Ties: The Core of Anti-Overturning
Check the number of tie bars as per the plan (vertical ≤ 4m, horizontal ≤ 6m), and whether any are missing, loose, or removed.
Check the correct connection method: Ensure they are rigidly connected to the main building structure (frame columns, shear walls). Do not attach them to scaffolding, railings, or non-load-bearing structures.
For scaffolding heights greater than 24m, ensure that the wall ties are rigidly connected (e.g., steel pipe brackets, embedded bolts), with no flexible alternatives (e.g., wire ropes).
5. Working Floor and Protective Facilities: Ensure Personnel Safety
Scaffolding: Are the scaffolds fully and securely laid? Are there any protrusions (extending 10-15cm beyond the small crossbar)? Are the joints/laps secure and free of cracks or looseness?
Guardrails and Footboards: Are 1.2m-high guardrails and 18cm-high footboards installed outside the uprights? Are the connections secure and free of missing or deformed components?
Safety Netting: Is the outer mesh netting taut and free of damage (mesh density ≥ 2000 mesh/100cm²)? Is it securely tied? Is a horizontal underlay net installed below the working floor as required?
Passageways and Entrances: Is the ramp slope appropriate (1:3)? Are there anti-slip strips (spaced 30cm apart)? Is the entrance and exit protective shed intact (double-layer protection)?
6. Load and Usage Specifications: Avoid Overloading Risks
Is the working floor overloaded? Check whether materials are evenly stacked, whether there are concentrated loads (such as large amounts of rebar or formwork), and whether a “Load Limit” sign (≤3kN/m²) is displayed.
Are there any illegal connections? It is strictly forbidden to secure concrete delivery pipes, pump pipes, guy cables, etc., to the scaffolding. It is strictly forbidden to use the scaffolding to lift heavy objects.
Are there any unauthorized component removals? Check whether key components such as wall ties, scissor braces, and guardrails have been illegally removed. If necessary, have approvals been obtained and reinforcement measures implemented?
Third, Inspection and Correction Records of Erected Scaffolding
Record Archiving: For each inspection, a “Scaffolding Safety Inspection Record Form” must be completed, indicating the inspection time, location, any defects found, responsible individuals for corrections, and the deadline. The form must be signed and confirmed by the inspector. Hazard Correction:
Minor issues (such as loose fasteners) must be immediately corrected by scaffolders.
Serious hazards (such as deformed uprights or missing wall connectors) require the scaffold to be immediately stopped from use, with warning signs posted. Use may only resume after rectification and acceptance.
After rectification is completed, re-inspection and confirmation of compliance are required, forming a closed-loop management system.
Summary
The core of daily inspections is “dynamic monitoring of structural safety + timely elimination of hazards.” This involves combining visual inspections (for deformation and corrosion), tool inspections (checking fasteners with a torque wrench), and load verification to ensure that the scaffold meets safety standards throughout its operation, preventing accidents such as collapse and falls.
