HIP END CONSTRUCTION

Hip end design has evolved to reduce traditional cut infill to a minimum and thereby keeping site labour and material costs down.
The main structural components of the trussed rafter hip end comprise a multi-ply hip girder, which supports the mono pitch trusses. A vastly reduced number of hip rafters form the hip.

Single flat-top infill trusses or hip intermediates are used to infill up to the first full truss at the end of the ridge. Generally the same truss spacing is preserved throughout the roof and into the hip for economic use of components. The intermediate hip trusses and hip girder are supplied with extended rafters for site fixing to the hip board.

The mono-pitch trusses are supported by mono shoes fixed on to a hip girder. A girder (or multiple) is composed of a number of identical trusses fixed together using nails, high tensile screws or bolts. Fixing details are supplied with your roof package.

Similar to the Standard Hip End, the multiple girder method is suitable for larger spans up to about 15 metres. Two or more multi-ply girders are used, with flat top infill trusses in between and maintaining the standard truss spacing.

The mono pitch rafters are economically designed to suit the truss rafter size.  Rarely and usually over very long spans, the rafters can be supported by posts from the substructure.
