The STHD is an embedded strap tie holdown with high load capacity and
designed to reduce spalling.
- A slot below the embedment line allows for increased front to
back concrete bond and reduced spalling.
- Rim joist models accommodate up to a 17" clear span without any loss
of strap fastening. Diamond holes for optional attachment to rim joist.
68 mil (12 ga).
Galvanized.
- Use all specified fasteners. See General Notes.
- Install before concrete pour with a StrapMate, or other holding device.
- Screw strap from the bottom up. Strap may be bent one full cycle.
- Bending the strap 90° to aid wall placement may cause spalling behind the strap. If the spall is 1" or less, measured from the embedment line to the bottom of the spall, full loads apply. For spalls between 1" and 4" (see illustration), the allowable load is 0.90 of the table loads. Any portion of the strap left exposed should be protected against corrosion.
- Where fewer fasteners are used in the structural member, reduce loads according to the code.
- Unless otherwise noted, do NOT install where: (a) a horizontal cold joint exists within the embedment depth between the slab and foundation wall or footing beneath, unless provisions are made to transfer the load, or the slab is designed to resist the load imposed by the anchor; or (b) slabs are poured over concrete block foundation walls.
- To get the full table load, the minimum center-to-center spacing is twice the embedment depth when resisting tension loads at the same time.
- There may be an increase in the amount of deflection if the strap is installed on the outside of the shear panel versus under the shear panel directly to the framing.
FOUNDATION CORNERS: Screw quantities may be reduced for less
than le corner distance design loads - use the code allowable loads for
fasteners in shear.
- To tie multiple stud members together, the Designer must determine the fasteners required to bind members to act as one unit.
- Additional studs attached to the shearwall studs or post may be required by the Designer for wall sheathing fastener.
- 1- #4 rebar must be installed in the shear cone
