Joist brackets are ideal for concealed load-bearing wood/wood connections of e.g. secondary beams to main beams or posts. Connections in visible areas can also be sloping.
- Easy on-site installation thanks to mounting slot in joist bracket blade
- Sheet metal hot-dip galvanised on both sides (S250GD +Z275 (approx. 20 µm)), thickness 3.0 mm in line with EN 10327:2004
- Application in utilisation classes 1 and 2 in line with EN 1995:2013
Proof of Performance
ETA-09/0105
Notice
The secondary beam can be mounted on the joist bracket attached to the main beam after the first dowel pin has been driven in to the uppermost hole in the secondary beam. To do this, the secondary beam with the uppermost dowel pin mounted in the slot area is hooked into the blade area of the joist bracket from above.
The secondary beam should be approx. 40 mm taller than the joist bracket. If the bracket is 90 mm in height, a secondary beam 100 mm in height can be used.
The diameter of the dowel pin may only be max. 0.5 mm (d = 8 mm) or 1.0 mm (d = 12 mm) smaller than the diameter of the hole.

| Notes: The measurement tables can only be used if all nails and rod anchors are inserted into the intended holes. The secondary beam should be about 40 mm greater in height than the joist bracket. The load-bearing capacities of the respective fasteners are determined in accordance with DIN EN 1995-1-1/NA. The force Fz,down and Fz,up act in the centre of the secondary beam. The main support must be secured to prevent torsion. The gap between the main support and the secondary beam must not exceed 8 mm. The transverse tensile capacity of the main support must be investigated separately. If necessary, a transverse tension reinforcement with ASSY plus FT screws must be used. For one-sided connections on the main support, the offset moment must be taken into account. The regulations of ETA-09/0105 must be applied.
