• 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

• 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
