Hip Ends and Corners
 
Hipped Corners

A hipped corner is formed by the intersection, at 90 degrees, of two roofs which may, or may not be the same span or pitch.
Hipped corners for mono-pitched and other roof shapes are based on the same principles described below for duo-pitched roofs. The common framing consist of a SECONDARY half-hip girder truss supported by a PRIMARY duopitch girder truss. An internal load-bearing wall or beam support can often be used to perform the function of the primary girder truss. The duo-pitch girder truss is specially designed for the exceptional loads it carries and includes a wider than normal vertical web to which a proprietory girder hanger can be fixed to carry the half-hip girder.
The roof is built up in the valley area using a monopitched valley set so that the half-hip girder carries the mono-pitch trusses and hipped corner infill, in
the same way as at a hipped end. The span of the mono-pitch trusses is not generally greater than 3 metres and more than one half-hip truss may be
needed between the ridge truss and the half-hip girder.
The details shown correspond to the method of construction used in the Step-down hipped end, in which noggins have to be sited between trusses to
support the tiling battens. Hipped corners with a Flying Rafter can also be
provided.
