META18 Embedded Truss Anchor
META18 Embedded Truss Anchor

The embedded truss anchor series provides an engineered method to properly attach roof trusses to concrete and masonry walls. The products are designed with staggered nail patterns for greater uplift resistance. Information regarding the use of two anchors on single- and multi-ply trusses is included.

Simpson Strong-Tie provides two different moisture barrier plates between the concrete/masonry and truss. The TSS is a preassembled, companion product of the META. The TBP8 seat plate also provides a moisture barrier installed prior to truss placement. The seat plate is installed with prongs, instead of fasteners.

The DETAL20 is a high-capacity embedded truss anchor for attachment of single-ply trusses to concrete and masonry walls. It combines dual embedded anchors with a structural moisture-barrier seat that is partially embedded in the concrete or grout. This seat serves to protect the truss and also provides additional lateral and uplift capacity. The embedded anchors are preattached to the moisture barrier through slots that allow for a slight amount of adjustability, providing flexibility during installation to avoid rebar. The moisture-barrier seat includes tabs at each end for optional attachment to the form board in concrete tie-beam applications.

Material:

HHETA 14 gauge; HETA 16 gauge; HETAL strap 16 gauge, truss seat 18 gauge; META 18 gauge; TSS/TBP8 22 gauge; DETAL 16 gauge (barrier 18 gauge)

Finish:

Galvanized (G90)

Installation:

Use all specified fasteners; see General Notes.

The META, HETA and HHETA are embedded 4" into a 6" min. concrete beam or 8" nominal grouted block wall; HETAL is embedded 5 1/16"; DETAL is embedded 4 1/2".

The DETAL20 is 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.

The TSS moisture barrier may be preattached to the truss using 0.113" x 2" nails.

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", install new anchors.

Minimum spacing of single anchors is twice the embedment depth for full load. For closer spacing, see loads for double anchor installation.

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.

For lateral loads listed, the lowest four nail holes shall be filled.

Straps do not need to be wrapped over the rafter/truss to achieve tabulated loads, unless noted otherwise.
