Bridle joint
Foundation detail
Different angles make this a complicated detail to construct.
The down part of the compression beam has to take all the
forces from the diagonal bigger beam in a relatively small
surface. It can not protrude further into the main beam, less it
becomes too weak at this point and buckles out. Therefore the
angles at this point are carefully chosen. There is no need for
dowels since there is only compression in this joint.
The horizontal forces of this diagonal beam are taken by the
horizontal tension rod. Left in this joint is the downward forces,
these are being taken by the horizontal steel plate that carries
the forces to the concrete foundation through a steel rod with a
diameter of 20 mm.
