- Clips, brackets and truss tie-downs
- Chemical, screw or wedge anchors to the slab
- Fixing schedules per panel
Connections carry the loads
In LGS the connections are as important as the members: screws join studs to tracks and truss members at nodes; hold-downs and anchors take uplift and overturning from braced walls; straps and brackets tie trusses to walls.
| Connector | Use |
|---|---|
| 10g – 14g self-drilling screws | Member to member |
| Hold-down + anchor rod | Braced wall ends to slab |
| Strap + tensioner | Diagonal wall bracing |
| Truss tie-down bracket | Roof uplift to wall |
| Anchors (chemical / screw) | Bottom track to slab |
Anchors
Bottom tracks and hold-downs are anchored to the slab with chemical anchors, concrete screws or cast-in bolts, designed for uplift and shear.
