Title: Selfdrilling Dowel WS for TimberSteel Joints


1
  • Self-drilling Dowel WS for Timber/Steel Joints

2
Dowel Joints
  • Application
  • Framework joints
  • Main/secondary purlin joints
  • Vertical strut bases
  • Properties
  • Load-bearing capacity depends on
  • accuracy of fit
  • installation spacing of pins
  • ductility (flow behaviour of the pin material,
    failure of the joint only after significant
    deformation)
  • Common method complicated production of joints
    with unsatisfactory quality

trusses
beam connections
vertical strut bases

5
  • Easy handling

1. Fitting the steel plates
2. Aligning and fixing it in position
3. Inserting the dowel
  • pilot drilling in timber
  • pilot drilling in steel
  • touching up

6
  • Self-drilling Dowels WS (Diameter 7 mm)
  • Framework gusseted joint as usual
  • with CNC trimming unit
  • cut metal plate to size
  • drill/punch metal plate, 0,5 - 1 mm larger than
    pin diameter
  • drill timber parts
  • slot timber parts
  • insert metal plate
  • drive in pin
  • additional operations without CNC trimming
  • make drilling template or draw drilling pattern
  • drill timber parts
  • insert metal plate, centre - drill or
    drill/punch in advance acc. to drilling pattern
  • insert metal plate again
  • Producing framework joints using the WS-System
  • cut metal plate to size
  • slot timber parts
  • insert metal plate
  • apply drilling pattern to timber parts
  • insert WS-fastener

7
  • Self-drilling Dowels WS (Diameter 7 mm)
  • General conditions
  • Maximum drilling capacity is 3 x 5 mm St 37.
  • Maximum metal plate thickness is 1 x 10 mm.
