Scaffolding is a temporary support structure commonly used in construction, maintenance, or aerial work. Its core features include the following:
1. Structural Stability
- 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, horizontal bars, 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 Protection
- Anti-slip Pedals: Bamboo fences, steel mesh panels, or wooden boards are installed on the work 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. Flexibility and Adaptability
Various Types:
- Coupler-Type Steel Tubular Scaffolding: Traditional, general-purpose scaffolding with low cost but time-consuming to erect and dismantle.
- Snap-On Scaffolding: Quick to assemble and dismantle, with strong load-bearing capacity, suitable for large-scale projects.
- Portal 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. Load-Bearing 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 Installation and Dismantling
- Tool-Based Operation: Some scaffolding types (such as snap-on scaffolding) require no bolts and can be quickly erected using latches.
- Transportability: Can be folded or transported in sections, reducing storage space.
6. 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. Compliance
Compliant Standards:
- China: GB 51210 “Unified Safety Technical Standard for Building Construction Scaffolding” 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.
Application Scenarios
- Construction: Exterior wall construction, formwork support, and renovation work.
- Industrial Maintenance: Equipment installation and pipeline maintenance.
- Stage Construction: Temporary stands and exhibition structures.
Purchasing and Usage Recommendations
- Choose the type based on project requirements: For high-rise buildings, the disc-type is preferred, while the door-type can be used for short-term renovations. – Erection must strictly adhere to specifications: avoid cutting corners (e.g., missing scissor braces).
- Suspension during inclement weather: Operations must be suspended in strong winds (≥ level 6), heavy rain, or snow.
