Traditional scaffolding requires on-site cutting of steel to size and welding and fastening. This process is tedious and relies heavily on worker skill, and the installation of a single scaffolding set can take several hours. However, prefabricated scaffolding components (such as channels, connectors, and bolts) are all prefabricated standard parts. On-site assembly requires simple bolting, eliminating the need for welding or extensive cutting. This reduces the installation time of a single scaffolding set to under 30 minutes, improving overall construction efficiency by over 60%. This can significantly reduce electrical installation time, especially in large-scale projects (such as subways and commercial complexes).
Traditional brackets rely on on-site manual fabrication, resulting in large dimensional errors (e.g., spacing and verticality deviations can exceed 10mm), which can easily lead to uneven load distribution and pose safety risks. Prefabricated brackets, on the other hand, are factory-fabricated according to design parameters, with component tolerances controlled within ±2mm. Connected via standardized joints, they strictly meet the bracket spacing and load-bearing capacity requirements of standards such as the "Code for Seismic Design of Building Mechanical and Electrical Engineering" (GB 50981) (e.g., horizontal pipe bracket spacing ≤1.5m, vertical pipe bracket spacing ≤2.0m), ensuring system stability.
Material Control: Prefabricated brackets are primarily made of hot-dip galvanized steel or aluminum alloy, with an anti-corrosion coating ≥85μm thick (traditional brackets painted on-site have a short lifespan due to the tendency for the coating to peel off). These brackets offer a service life of over 15 years in humid and dusty environments (such as underground garages and chemical workshops), 3-5 times that of traditional brackets. - Structural Load-Bearing: Through optimized design based on mechanical calculations, the bracket's shear and bending resistance is clearly defined (for example, the finished C-shaped steel bracket can withstand linear loads of 500-2000N/m), eliminating the risk of fracture associated with poor welding quality in traditional brackets.
Environmentally Friendly: Traditional brackets require on-site welding, generating dust and noise pollution, and steel cutting produces significant waste. The finished brackets require no on-site welding, resulting in a waste rate of less than 5%, meeting green construction requirements.
Post-Maintenance: The finished brackets feature detachable connections. If pipes or cables need to be modified or replaced, the bolts can be loosened to adjust their position without disrupting the structure. Modifications to traditional welded brackets require cutting and re-welding, which is costly and impacts surrounding systems.
In seismic fortification areas (e.g., areas with an earthquake intensity of 6 or higher), prefabricated scaffolding can be connected to the building structure through dedicated seismic nodes (such as braces and dampers), meeting seismic fortification intensity requirements (e.g., scaffolding displacement ≤ 50mm at a horizontal earthquake acceleration of 0.4g). Traditional scaffolding lacks standardized seismic design and therefore struggles to pass seismic inspections.
In summary, prefabricated scaffolding, through its standardized and modular design, surpasses traditional scaffolding in terms of efficiency, quality, and safety, making it particularly suitable for large-scale, high-standard building mechanical and electrical projects.
