The capacities are given for one ABR, in the case, that in total more ABR are placed alternate opposite on the beam.

It's given the option to fix the ABR with only one bolt (the upper one) for only the load in direction F₁ and F₆, the capacity for F₁ is in this case the half.

The distance of the beam to the support shall be less than 132 mm for ABR220, and less than 86 mm for ABR170.

Technical Notes

Technical info

Particular situation with two angle brackets per assembly positioned opposite to each other

F1 Continious force in the central axis of the purlin.

F2 and F3 Lateral force that works between the purlin and the beam in the purlin direction.

F4 and F5 Lateral force that works in the center of the angle brackets in the beam direction positioned e above the beam.

Particular situation with only one angle bracket per assembly

F1 Continious force in the central axis of the purlin with a distance f between the vertical contact surface. If the overall structure prevents the rotation of the purlin or the post, the tensile strength is equal to half of the given value for two angle-brackets.

F2 and F3 Lateral force that works between the purlin and the beam in the purlin direction.
F4 Lateral force that works in the center of the angle brackets in the beam direction. Works towards the bracket positioned e above the beam.

F5 Lateral force that works in the center of the angle brackets in the beam direction. Works away from the bracket positioned e above the beam.
