Hoisting

Hoisting trusses to the top of the wall needs to be done in a manner that does not over stress the truss. Plated wood trusses are strong in a vertical, braced position but during assembly they can be damaged by bending out of their normal flat plane. When lifting short trusses by hand, use a pair of ramps built of 2x material from the ground to the top of the wall to support the truss while sliding it up. For longer span trusses which are being lifted individually by a crane see the drawings below for proper rigging details.

Two items need to be addressed during construction to prevent problems caused by truss uplift. First the partitions should be connected to the truss bottom chord with a slotted 'L' bracket to allow vertical movement of the truss. Secondly the ceiling drywall should not be connected to the truss within 18" of the partitions. The simple use of 2x6 blocking on top of the 2x4 wall plate will provide a fastening point for the drywall which will stay with the wall. The ceiling drywall will flex from the blocking to the first fastener to the truss. Click on the diagram for a more detailed view of this connection.
