Connection of jack and hip trusses at a hip-end roof for design wind classification N4, C2 or C3 shall be in accordance with the details shown. These details are suitable for a maximum truncated girder station of 3600mm.

Figure C2-02-01-01

Note 1:
For effective skew nailing, the nail shall be driven into one member not closer than 25mm to no more than 38mm from the arrea in contact with the adjacent member. The nail shall be driven at an angle between 30° and 45° to the face into which the nail is driven.

Note 2:
Where nails are smaller than the nominated size or other than plain shank nails, or machine driven, or both, their performance shall not be inferior to the nail sizes given.

Note 3:
Roof battens or purlins and ceiling battens shall be fixed to trusses in accordance with the approved specifications.

Note 4:
Where framing anchors or G.I. straps are specified, they shall be fixed in accordance with the approved specifications.

Note 4:
Jack trusses are assumed to be supported on the horizontal top chord of the truncated girder.
