Embedded Truss Anchors and Truss Seat Snap-in


Installation

View step-by-step installation instructions

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 multiple-ply trusses is included.

The TSS, a companion product of the META, provides a moisture barrier between the concrete and truss. The preassembled unit is riveted with no height adjustment.

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 pre-attached 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—22 gauge; DETAL—16 gauge (Barrier—18 gauge).

Finish: Galvanized. Some products available in ZMAX® coating; see Corrosion Information.

HETA20 now available in stainless steel.

Additional Corrosion Protection

These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

Table
  1. Loads have been increased for wind or seismic loading. Reduce where other loads govern.
  2. Minimum f'c = 2500 psi. Minimum f'm = 1500 psi.
  3. For simultaneous loads in more than one direction, the connector must be evaluated as described in under Instructions to the Designer.
  4. Five nails must be installed into the truss seat of the HETAL.
  5. Parallel-to-wall load towards face of HETAL is 1975 lbs.
  6. It is acceptable to use a reduced number of fasteners provided that there is a reduction in uplift load capacity. See example. Lateral loads do not apply when fewer than 7 fasteners are used with the HETA and HHETA anchors or less than 6-16d or 7-10dx1 1/2" fasteners are used with the META anchor.
  7. The HHETA allowable F1 load can be increased to 435 lbs. if the strap is wrapped over the truss and a minimum of 12 nails are installed.
  8. Minimum spacing for multiple anchor installation is 2 times the embedment depth for full load. See Double Embedded Anchor Installation table for loads on closer spaced anchors.
  9. Minimum edge distance for HETA/META is 1 1/2" for concrete and 2" for masonry.
  10. NAILS: 16d = 0.162" dia. x 3 1/2" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long. See other nail sizes and information.

Table
  1. Loads include a 60% load duration increase on the fasteners for wind or seismic loading.
  2. Minimum f'c = 2500 psi. Minimum f'm = 1500 psi.
  3. For simultaneous loads in more than one direction, the connector must be evaluated as described in Instructions to the Designer.
  4. Install with spoons facing outward and straps spaced no more than 1/8" wider than the truss width.
  5. The DETAL20 requires 6-10dx1 1/2" nails in the truss seat and 6-10dx1 1/2" nails into each strap. For all other models, install half of the required fasteners in each strap.
  6. Lateral loads for META, HETA and HHETA anchors apply only to 2- or 3-ply applications with anchors spaced a minimum of 3" apart. For single-ply applications use lateral loads from the Single Embedded Anchor Installation table. DETAL lateral loads apply for single-ply application.
  7. F1 lateral loads listed may cause an additional 1/16" deflection beyond the standard 1/8" limit where the
    straps are installed not wrapped over the heel as shown.
  8. Two HHETA anchors may be installed in a concrete tie beam on a 2- or 3- ply truss with 2 fewer nail for an allowable uplift load of 3050 lbs.
  9. Noted F1 lateral loads for the DETAL20 may cause an additional 1/32" deflection beyond the standard 1/8" limit.
  10. Single ply trusses may use either 10dx1 1/2" or 16d nails with allowable loads limited to the single ply column. 2- or 3- ply trusses shall use 16d nails.
  11. NAILS: 16d = 0.162" dia. x 3 1/2" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long. See other nail sizes and information.
