Important Interpretations:
Foundation Specifications:
Requires soil bearing capacity ≥10 t/m² for areas with ≤11 t/m² loads
Anchor bolts sealed with concrete post-installation
Structural Details:
Square foundation dimensions not explicitly stated (only shown in diagrams)
"0.114*3.0" notation not fully deciphered (possibly related to bolt pattern)
"B" length specifier for M36 bolts remains undefined
Material Notes:
Q235 steel equivalent to ASTM A36 (yield strength 235 MPa)
Concrete grades: C10 (7.5 MPa) for cushion, C20 (20 MPa) for main foundation
Electrical Grounding:
Galvanized pipe used for grounding (diameter unspecified)
Resistance must be <10 ohms per electrical safety standards
Construction Requirements:
Foundation depth adjustable per local regulations (minimum 2.8m shown)
100mm foundation exposure above final grade
All steel components hot-dip galvanized for corrosion protection
