1. Scaffolding Must Comply with Design Specifications
The scaffolding design must be carried out in strict accordance with the Safety Technical Standard for Ringlock Steel Scaffolding in Building Construction (JGJ/T 231), which specifies key parameters such as vertical pole spacing, horizontal pole step distance and wall tie setting. In actual construction, designers should fully combine the specific project needs, construction environment and structural characteristics, accurately calculate and reasonably determine various parameters to ensure the scientific, reasonable, safe and reliable scaffolding design.
For load management, clarifying the maximum allowable load of scaffolding is the key to ensuring safe use. Generally, the maximum allowable load of structural scaffolding shall be controlled within ≤3kN/m², and that of decoration scaffolding within ≤2kN/m². Overloading or applying concentrated loads on the scaffold is strictly prohibited during construction to avoid structural instability caused by excessive loads. In addition, construction units should set load signs at prominent positions of the scaffolding to clearly inform operators of the bearing capacity, and strengthen safety education and management to improve their safety awareness.
2. Strictly Implement Material Acceptance of Ringlock Scaffolding
Material quality is the fundamental guarantee for the safety of Ringlock scaffolding. During material entry acceptance, a comprehensive and detailed inspection shall be carried out on the steel pipe wall thickness, buckle joint weld quality, vertical pole verticality and integrity of accessories. The steel pipe wall thickness shall be ≥3.2mm to ensure sufficient strength and stability; joint welds shall be full and uniform without defects such as cold welding and missing welding; vertical pole verticality deviation shall be within the allowable range; accessories shall be complete and intact without damage or loss. Materials with defects such as deformation, corrosion and cracks must be cleared out of the site and strictly prohibited from construction use.
During node inspection, connectors such as pins and wedge-shaped fasteners shall be fully locked, and vertical poles, horizontal poles and diagonal poles shall be accurately positioned according to the design to form a stable triangular structure, which can effectively improve the overall bearing capacity and anti-overturning ability of the scaffolding. Professional testing tools and methods shall be adopted to inspect the node connection quality to ensure firm and reliable connection.
3. Standardize the Erection and Dismantling Process of Ringlock Scaffolding
Standardized construction process is the key to ensuring safety during the erection and dismantling of Ringlock scaffolding. Before erection, foundation treatment shall be completed to ensure the foundation bearing capacity is not less than 150kPa, including foundation compaction and laying of base plates or channel steel to prevent scaffold inclination or collapse caused by uneven foundation settlement. Meanwhile, a detailed erection plan shall be prepared according to the project conditions.
During erection, follow the principle of "from bottom to top, layer by layer", and install diagonal braces and wall ties synchronously. High-altitude throwing operations are strictly prohibited. Erectors must hold corresponding certificates and strictly abide by operating procedures.
Scaffolding dismantling shall be carried out from top to bottom following the rule of "erect first, dismantle later". A warning area shall be delineated and special personnel assigned for supervision. Dismantled components shall be stored classifiedly for subsequent maintenance and reuse.
4. Strengthen Safety Management During Scaffolding Use
Strengthening safety management during scaffolding use is an important measure to detect and eliminate potential safety hazards in a timely manner. Construction units should establish a complete daily inspection system, focusing on checking whether the scaffold is deformed, nodes are loose, and wall ties are missing.
Meanwhile, safety protection in the operation area shall be strengthened: the working layer shall be fully paved with scaffold boards; 1.2-meter-high guardrails and dense-mesh safety nets shall be set on the outer side; horizontal safety nets shall be erected at the lower part. Protection facilities shall be inspected and maintained regularly to ensure their integrity.
5. Formulate Scientific Plans for Special Working Conditions of Scaffolding
For special working conditions such as cantilever structures and special-shaped structures, targeted plans shall be formulated. For cantilever structures, steel cantilever beams shall be used for anchoring, and the ratio of cantilever length to anchoring length shall be ≤1:1.25.
For special-shaped structures such as corners and openings, special design shall be carried out with additional diagonal braces and reinforcement measures to ensure overall stability. Construction shall be carried out in strict accordance with the design plan.
6. Improve the Emergency Response and Accident Prevention Mechanism
Construction units should formulate comprehensive emergency plans for sudden accidents such as scaffolding collapse and high-altitude falls, and organize regular drills. The plans shall clarify emergency response procedures, rescue measures and evacuation plans to minimize losses.
A clear accident reporting process shall be established. After an accident, the emergency plan shall be activated immediately, rescue work shall be carried out promptly, and accident investigation and analysis shall be strengthened to avoid recurrence of similar accidents.
Scaffolding safety technical disclosure covers design, materials, erection, use, special working conditions and emergency disposal. Engineering practitioners should strictly abide by relevant standards and do a good job in scaffolding safety management to ensure construction safety and quality.
