FASTENER TECHNICAL DETAILS
FASTENER SYSTEM
NOTE: load capacity used for calculation N
rec
= 1.8 kN (axial) / V
rec
= 2.6 kN (shear)
Application
• Fastening of cable trays, pipes on a horizontal cantilever support, fastened on
a vertical structure
• Support is fastened by two / four S-BT on both support and brace baseplate
with distance x
• L1 is the distance of the load center to the vertical structure surface
• Load F is the acceptable total load (all dead load including)
Boundary conditions
• These values are ONLY reflecting capacity of S-BT threaded stud. Structural
analysis of support / structure is NOT in Hilti scope. See the detailed
statements in disclaimer — 2018/05/04
• Shear load fully carried by one / two top S-BT (worst-case)
• Load F acting at the distance of L1 from structure surface
