In the construction industry, scaffolding is widely used in various projects due to its many advantages, including its rational structure, safety, reliability, and ease of installation. However, despite its excellent performance, improper operation during installation and use can pose significant safety risks, such as collapse and falls from height, seriously threatening the lives of construction workers and the smooth progress of the project. Safety technical briefings are a critical pre-construction step. Through systematic and professional training, engineers and construction personnel can fully understand the operating procedures, risk factors, and emergency response measures for scaffolding, eliminating safety hazards at the root and ensuring project safety and quality.
First, scaffolding must comply with design specifications.
During the design phase of scaffolding, strict compliance with the “Safety Technical Standard for Socket-and-Spigot Steel Pipe Scaffolding in Construction” (JGJ/T 231) is essential. This standard clearly and meticulously specifies key parameters such as vertical bar spacing, horizontal bar pitch, and wall tie placement. In actual construction, designers must fully consider the specific project requirements, construction environment, and structural characteristics, accurately calculating and rationally determining various parameters to ensure a scientific, rational, safe, and reliable scaffolding design. Regarding load management, clearly defining the scaffold’s maximum allowable load is crucial for ensuring its safe use. Generally speaking, the maximum allowable load for structural scaffolding should be controlled to ≤3kN/m², and the maximum allowable load for decorative scaffolding should be controlled to ≤2kN/m². During construction, overloading or applying concentrated loads to the scaffolding is strictly prohibited to prevent structural instability caused by excessive loads. Furthermore, construction companies should prominently display load signs on the scaffolding to clearly inform construction workers of the scaffold’s load-bearing capacity. This should strengthen safety education and management for construction workers and enhance their safety awareness and sense of responsibility.
Second, strictly implement material inspections for interlocking scaffolding.
Material quality is the fundamental guarantee for the safety of interlocking scaffolding. During the incoming material inspection, a thorough and detailed inspection should be conducted on the steel pipe wall thickness, the quality of the welds at the clasp joints, the verticality of the poles, and the integrity of the accessories. The steel pipe wall thickness should be ≥3.2mm to ensure sufficient strength and stability. The weld quality of the clasp joints should meet relevant standards, with full and uniform welds and no defects such as cold or leaky welds. The verticality deviation of the poles should be within the allowable range to ensure the overall verticality of the scaffolding. Accessories should be complete and free of damage or missing parts. Materials showing defects such as deformation, rust, or cracks should be resolutely removed from the site and strictly prohibited from use in the construction. During the joint inspection, it should be ensured that connectors such as latches and wedge fasteners are securely locked in place, and that the vertical and horizontal diagonal bars are accurately positioned according to the design to form a stable triangular structure. The triangular structure provides excellent stability and lateral force resistance, effectively improving the overall load-bearing capacity and anti-overturning resistance of the scaffolding. Furthermore, during the joint inspection process, professional testing tools and methods should be used to rigorously inspect the joint connection quality to ensure a secure and reliable connection.
Third, the specifications for interlocking scaffolding clearly define the erection and dismantling procedures.
During the erection and dismantling of interlocking scaffolding, standardized construction procedures are crucial to ensuring construction safety. Before erection, the foundation should be prepared to ensure a bearing capacity of 150 kPa or higher. Specific measures include compacting the foundation and installing pads or channel steel to prevent uneven foundation settlement from causing the scaffold to tilt or collapse. Furthermore, the scaffolding height and extent should be determined based on the project’s specific circumstances, and a detailed erection plan should be developed. During erection, the principle of “erecting from bottom to top, layer by layer” should be followed, with diagonal braces and wall ties installed simultaneously. Overhead work is strictly prohibited. Diagonal braces and wall ties are crucial components for enhancing the scaffold’s stability and wind resistance. They should be installed promptly according to design requirements to ensure the safety and stability of the scaffold during erection. Furthermore, erection personnel should possess the appropriate skills and experience and strictly adhere to operating procedures to ensure the quality of the scaffolding. When dismantling scaffolding, work should proceed from top to bottom, installing first and dismantling later. A cordoned-off area should be established and monitored by designated personnel. Throwing components during dismantling should be strictly prohibited to prevent casualties or property damage from falling components. Dismantled components should also be classified and stored according to regulations to facilitate subsequent repair and use.
Fourth, Strengthen Safety Management During the Operation of Interlocking Scaffolding
Strengthening safety management during the operation of interlocking scaffolding is a key measure to promptly identify and eliminate safety hazards. Construction units should establish a comprehensive daily scaffolding inspection system, checking for deformation, loose joints, and missing wall connectors. Inspectors should possess professional knowledge and skills to accurately assess the safety status of the scaffolding and promptly implement appropriate measures. Furthermore, safety measures for the scaffolding working area should be strengthened. The working floor should be fully covered with scaffolding to ensure the safety of construction workers. 1.2m-high guardrails and dense safety nets should be installed on the outside to prevent falls. Horizontal safety nets should be installed underneath to further enhance safety. Furthermore, protective equipment should be regularly inspected and maintained to ensure it remains intact and functions effectively.
Fifth, Develop Scientific Solutions for Special Working Conditions for Interlocking Scaffolding
In construction projects, interlocking scaffolding may encounter some special working conditions, such as cantilever structures and irregularly shaped structures. For cantilever structures, steel cantilever beams should be used for anchoring, ensuring precise positioning of the vertical poles and a ratio of cantilever length to anchor length of ≤1:1.25. Furthermore, stress analysis and calculations of cantilever structures should be strengthened to ensure sufficient load-bearing capacity and stability. For irregularly shaped structures, such as corners and openings, specialized designs should be implemented, with additional diagonal braces and reinforcements to ensure overall stability. During the design process, the structural characteristics and stress conditions of the special-shaped scaffolding should be fully considered, and appropriate structural forms and connection methods should be adopted to enhance its safety and reliability. Furthermore, during construction, the design plan should be strictly adhered to to ensure the quality of the special-shaped scaffolding.
Sixth, Complete Emergency Response and Accident Prevention Mechanisms for Interlocking Scaffolding
To effectively address potential accidents such as collapse and falls from height associated with interlocking scaffolding, construction companies should develop scientific and comprehensive emergency response plans and conduct regular drills. These plans should include emergency response procedures, rescue measures, and evacuation plans to ensure prompt and effective rescue and response in the event of an accident, minimizing losses. Furthermore, a clear reporting process for emergencies should be established to ensure the timely and accurate transmission of accident information to relevant departments and personnel. Following an accident, construction companies should immediately activate the emergency response plan, organize rescue teams, and promptly report the accident to higher authorities. Furthermore, they should strengthen accident investigation and analysis, summarize lessons learned, and implement effective measures to prevent similar accidents from recurring.
The safety technical briefing for the scaffolding covers several key aspects, including design, materials, erection, use, special working conditions, and emergency response. Construction professionals should fully recognize the importance of safety technical briefings, strictly follow relevant standards and specifications, and do a good job in the safety management of the scaffolding to ensure the safety and quality of the construction.
