  1. Come with the joist,
  2. Add nails. It can be also screwed,
  3. If the header is made out of timber, the angle bracket can be attached to it with nails or screw,
  4. If the header is made out of concrete, the angle bracket must be attached with adapted anchors (using the installation data from the anchor)

Technical Notes


F1: tensile force in the central axis of the angle-bracket
Particular situation of a fastening with only one angle-bracket:

  • 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.
  • Otherwise, the connection resistance depends on the « f » distance between the vertical contact surface and the point of load application.

F2 and F3: shear lateral force
Particular situation of a connection with only one angle-bracket:

  • The resistance value to consider is equal to half of the one given for two angle-brackets.

F4 and F5: transversal force directed towards or opposite the angle-bracket

  • The connection resistance depends on the « e » distance between the base of the angle-bracket and the point of load application.
  • To consult corresponding loads, contact us.

Only F1, F2 and F3 forces for connections with 2 angle-brackets are present on this sheet.
