Scaffolding is a temporary support structure commonly used in construction, maintenance, or aerial work. Its core features include the following:
1. Structural Stability of Scaffolding
- High-strength Materials: Typically, steel pipes (such as Q235 carbon steel), aluminum alloys, or composite materials are used to ensure load-bearing capacity.
- Modular Design: Standardized components (vertical poles, crossbars, diagonal braces, etc.) can be flexibly assembled to accommodate various heights and shapes.
- Stable Foundation: A base or pad is required to prevent settlement. Soft soil foundations require additional reinforcement.
2. Safety and Protective Features of Scaffolding
- Anti-slip Pedals: Bamboo fences, steel mesh panels, or wooden boards are installed on the working platform to prevent workers from slipping.
- Guardrails and Toeboards: 1.2m high guardrails and 18cm high toeboards are required at aerial work platforms (complying with standards such as GB 51210).
- Fall Prevention Measures: Safety nets, lifelines, or personal protective equipment (such as safety belts) can be used.
3. Scaffolding Flexibility and Adaptability
- Diverse Types:
Cabled Steel Tubular Scaffolding: Traditional, general-purpose scaffolding with low cost, but time-consuming to erect and dismantle.
Hook-and-loop Scaffolding: Quick to assemble and dismantle, with strong load-bearing capacity, suitable for large-scale projects.
Gate-type Scaffolding: Lightweight and easy to move, commonly used in interior decoration.
Cantilever Scaffolding: Used for high-rise building facade construction.
- Adjustability: Height and span can be adjusted according to construction requirements, accommodating complex structures (such as curved surfaces and special-shaped buildings).
4. Scaffolding Load Capacity
- Static Load: Supports the weight of construction materials, equipment, and workers (generally designed to carry ≥ 2 kN/m²).
- Dynamic Load: Considers external forces such as wind pressure and vibration, requiring mechanical verification.
5. Ease of Scaffolding Installation and Dismantling
- Tool-Based Operation: Some scaffolding types (such as hook-and-loop scaffolding) require no bolts and can be quickly erected using latches.
- Convenient Transportation: Can be folded or transported in sections, reducing storage space.
6. Scaffolding Durability and Maintenance
- Anti-corrosion Treatment: Hot-dip galvanizing, plastic spraying, and other processes extend outdoor service life.
- Regular Inspections: Check for deformation, rust, loose connections, and other issues to ensure safety.
7. Scaffolding Compliance
Standard Compliance:
China: GB 51210 “Unified Safety Technical Standard for Scaffolding in Building Construction” and JGJ 130 “Safety Technical Specification for Coupler-Type Steel Pipe Scaffolding.”
International: EN 12811 (Europe), OSHA (US Occupational Safety Standard).
Acceptance Procedure: After erection, professional acceptance is required before use.
8. Scaffolding Applications
Construction: Exterior wall construction, formwork support, and renovation work.
Industrial Maintenance: Equipment installation and pipeline inspection.
Stage Construction: Temporary stands and exhibition structures.
9. Scaffolding Selection and Usage Recommendations
Choose the type based on project requirements: For example, a truss-type scaffold is preferred for high-rise buildings, while a portal-type scaffold can be used for short-term renovations.
Erect scaffolding strictly according to specifications: Avoid cutting corners (e.g., missing scissor braces).
Suspend scaffolding in inclement weather: Suspend operations in strong winds (≥ level 6), heavy rain, or snow.
