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 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/TBP8 — 22 gauge; DETAL — 16 gauge (barrier — 18 gauge).

Finish

  • Galvanized. Some products available in ZMAX® coating. See Corrosion Information.

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 6d commons.
  • 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.
  • In double embedded anchor installations, do not install fasteners where the straps overlap when wrapped over the truss heel.
  • For lateral loads listed, the lowest four nail holes shall be filled.

Load Tables

Single Embedded Anchor Installation

    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.

  1. Loads have been increased for wind or seismic loading. Reduce where other loads govern.
  2. Minimum f'c = 2,500 psi. Minimum f'm = 1,500 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 1,975 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) 10d x 1 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. Where edge distance is between 1 1/2" and 2" for masonry, the maximum uplift load is 1,005 lb.
  10. Calculate the connector value for a reduced number of nails as follows:
    Allowable Load = (No. of Nails Used / No. of Nails in Table) x Table Load
  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.

Double Embedded Anchor Installation

  1. Loads include a 60% load duration increase on the fasteners for wind or seismic loading.
  2. Minimum f'c = 2,500 psi. Minimum f'm = 1,500 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) 10d x 1 1/2" nails in the truss seat and (6) 10d x 1 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 F1 = 640 lb. and F2 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 two fewer nails for an allowable uplift load of 3,050 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 10d x 1 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.
