1. Scaffolding Foundation Inspection: Bearing Capacity and Base Plate are Core
The foundation ground must be flat and compact, with allowable settlement ≤10mm and no cracks; the compaction coefficient of backfilled foundation ≥0.94 (tested by ring knife method). The base plate shall be wooden (length ≥2 spans, thickness ≥50mm) or rigid (such as channel steel), with contact area ≥0.15 ㎡. Our company’s special rigid base plate, made of Q235 steel with anti-corrosion treatment, avoids wood plate loss and ensures stable foundation stress.
2. Scaffolding Vertical Pole Inspection: Verticality and Joint Arrangement Determine Stability
Verticality deviation ≤1/200 of the scaffold height; butt fasteners must be used (lapping is strictly prohibited), and adjacent joints shall not be in the same step. The torque of fasteners shall be 40～65N·m. Our poles are equipped with positioning marks to avoid "joints in the same span" and improve inspection efficiency.
3. Scaffolding Crossbar Inspection: Step Distance and Connection Affect Force Transmission
Longitudinal crossbars (length ≥3 spans) and transverse crossbars (spacing ≤400mm for bamboo planks) shall be arranged as required, with step distance ≤1.8m and longitudinal spacing ≤2m. Our longitudinal crossbars adopt cold drawing process, with straightness deviation ≤1mm/m, ensuring vertical connection with vertical poles.
4. Scaffolding Fastener Inspection: Material and Torque Prevent Connection Failure
Fasteners shall be made of malleable cast iron or cast steel (in line with GB15831), without cracks or deformation. Our fasteners pass mechanical performance tests, with anti-damage load ≥25kN and galvanized bolts for better rust resistance.
5. Scaffolding Wall Tie Inspection: Reliable Attachment Points Prevent Instability
Wall ties shall be set close to main nodes (distance ≤300mm), preferably rigid ones. For scaffolds below 24m, wall ties shall be set per 3 steps and 3 spans. Our rigid wall tie accessories can be directly connected to the building structure without on-site processing.
6. Scaffolding Diagonal Bracing Inspection: Full-Height Continuous Arrangement for Overall Reinforcement
Diagonal bracing shall be continuously set along the full height of the scaffold outer side (width ≥4 spans or ≥6m), with an angle of 45°～60° with the ground. Lapping length ≥1m, fixed with 3 rotary fasteners. Our diagonal bracing, made of Q235B steel, ensures effective force transmission.
7. Scaffold Plank Inspection: Strict Management from Material to Fixation
Decayed or deformed planks are prohibited. Our galvanized steel planks (Q235) have anti-slip grooves, a service life of 5～8 years, and built-in hooks for reliable fixation, fully complying with JGJ130 standards.
Scaffolding inspection is a responsibility to construction workers’ lives. Each link must meet standards. Choosing our compliant products (steel planks, fasteners, base plates, etc.) can reduce rectification costs and build a solid safety line from the source.
