7. Purlin Installation
The Sigma S1 System uses purlins mounted on the
girder to hold the modules in place. Purlin clamps
are used to secure the purlins to the girder.
Note:
Depending on project specifications, additional
purlins may be required. Refer to the project-
specific drawings.
7.1. Purlin Placing and Alignment
Installation Steps
1. Position the purlins horizontally on top of the
rafters and align them. Please refer to the
project drawings for the exact position of the
purlins with regards to:
- Spacing between purlins
- Horizontal overhang (cantilever) over
the outer driven piles
2. Loosen the purlin clamps pre-assembled into
the girder. Clamp both sides of the purlin to the
purlin clamps.
3. Check that the spacing of the purlins does not
get shifted with the final tightening of the
bolts. Readjust if necessary.
4. Adhere to the specified tightening torques
7.2. Purlin Connector
The purlins are spliced together using a purlin
connector.
Mounting Steps
1.
Slide the purlin connector halfway into the
installed purlin. Secure the connector to the
purlin by drilling 2 self-tapping screws into the
pre-drilled holes in the connector.
2. Slide the next purlin into the connector leaving
no gaps between the 2 purlins. Secure the 2
nd
purlin by drilling another 2 self-tapping screws
into the pre-drilled holes in the connector.
3. Adhere to specified tightening torques.
