Frame Sub-Assembly - Dexion HI280 Construction Manual

Frame Sub-Assembly

A jig frame is assembled in accordance with the "Frame Assembly Schedule". All the fixings are
made and the jig frame is checked for squareness. This frame is then laid on a flat bed made up
from convenient materials, usually stacks of wooden pallets, at a comfortable working height. This
frame then forms a template on which all subsequent frames are assembled.
All the component parts that are required for the frame assembly are then sited at convenient
positions around the jig.
Connection of the battens, braces, cladding etc. to the uprights will be either swaged or riveted.
The type of fixing will be detailed with the supply of materials.
These connections are always made from the open side of the upright web.
To ensure correctly aligned connections it is important to keep the frame level during assembly.
The best way to achieve this is to use packers under the battens, braces, cladding, and under the
upright web.
These packers should not be positioned where a fixing is required as they will interfere with either
the swage tool or the rivet.
Swaged connection
If swaged connections are being used the tool must first pass through the swage hole in either the
batten or cladding sheet and then through the oval hole in the upright web. Once the tool has
passed through both sections it can be rotated through 180° to make the connection.
Riveted connection
If riveted connections are being used the rivet must first pass through the hole in the batten or
brace and then through the round hole in the upright web.
Turning the frame over during assembly
To ensure the fixing first passes through the batten, brace, cladding, the connection needs to be
made from the open side of the upright web. Therefore start by making the connections to the first
upright, and then turn the assembly over to continue making the connections to the open side of
the second upright.
