AAC Construction Components
Connections
- The roof frame/framing is connected to a conventional top plate or hurricane straps embedded in the bond beam.
- Floor framing is attached with standard ledgers anchored to the side of the AAC assembly adjacent to a bond beam.
- AAC floor systems bear directly on top of AAC walls.
- More prominent structural steel members are set on weld plates or bolt plates set into the bond beam.
Fasteners
A combination of nails, anchors, ledger bolts and screws is used during the installation process.
Beyond the Basics
Second-floor ledgers will be grouted into a bond beam course for the second-floor joists. Pictured on the right is an example of this application, along with a sample of three typical window openings. The window bucks are easily placed by simply putting a deck screw through the 2x6, or the preferred method would be to use the Quick Header system. Home - Quick Headers
The last course of the building is a continuous bond beam course system. Finally, a Simpson LTA2 is placed as an attachment point for engineered roof trusses. This makes installing the roof system a practical and straightforward process.
