The Simpson DETAL high-capacity embedded truss anchor combines dual embedded anchors with a structural moisture-barrier seat that serves to protect the truss and also provide additional lateral and uplift capacity. This anchor provides an engineered method to attach single-ply trusses securely to concrete and masonry walls. The embedded anchors of the DETAL are preattached to the moisture barrier through slots that allow some adjustment during installation to avoid rebar.
Installation :
- Tabs at each end of moisture-barrier seat, for optional attachment to the form board in concrete tie-beam applications.
- Strap can be installed straight or field-bent around truss or rafter members and is load rated for wind and seismic forces.
- Installed centered and flush on top of an 8″ masonry bond beam or concrete tie beam. The moisture-barrier seat bears on masonry face shell or concrete tie beam form boards; the two flanges embed into grout or concrete. The two embedded anchors shall be installed vertically into grout or concrete.
- For mislocated truss anchors which are greater than 1/8″ but less than 1 1/2″ from the face of the truss, a shim must be provided. Shim design by truss engineer. When gap is greater than 1 1/2″, abandon existing embedded truss anchor and install new anchor per designer.
- For lateral loads listed, the lowest four nail holes must be filled.
- Minimum spacing between the anchors to achieve full load is twice the embedment (Embedded 4 1/2″).
- In double anchor installations, install anchors with spoons facing outward and straps spaced no more than 1/8″ wider than the rafter/truss width. Do not install nails where the straps overlap when wrapped over the rafter/truss.
- Straps don’t need to be wrapped over the rafter/truss to achieve tabulated loads, unless noted.
NOTE: The correct fasteners installed in the correct position must be used to achieve published load values.
