Shear connectors

!
Attention must be paid to the manufacturer's fitting
instructions and the minimum anchoring depths.
!
Use must be made of adequately dimensioned packing
plates for the shear connectors.
i
The minimum length (L) of the anchor rod of the
shear connector must be determined on site. The
drill diameter and the tightening torque for the shear
connector are type-specific (refer to manufacturer's
specifications).
Fig. 1: Calculating minimum length of shear connector L = g +
t + s + h
L Minimum length of anchor rod
h Minimum setting depth (as specified by shear connector manu-
facturer)
s Thickness of screed including tiles
t Thickness of base plate of lifting platform column
g Visible thread length
B Minimum thickness (refer to Section 3.2)
i
For concrete C20/25 we recommend a minimum
thickness of 21 cm and use of the shear connector
Hilti HVA/HAS-M16x125.
