#75: POS-I-TIE® Brick Veneer Anchoring Systems
The POS-I-TIE®
is a two piece system for attaching Brick Veneer to various
existing backups. It incorporates a barrel-screw piece which
allows easy installation using an ordinary drill with a
special chuck adapter.
For backups
with insulation or gypsum board, the screw penetrates the
insulation, screws into the backup, and then prevents
moisture penetration by sealing the hole in the insulation
with a neoprene washer.
The barrel makes a positive contact
with the backup wall transferring all compression and
tension loads to the backup wall and not to the insulation/gypsum
board.
The screws
are a part of the system; therefore, no inferior screws
can be substituted. The barrel is manufactured of ZAMAC
3 - a 92% zinc alloy. The screws are heat treated and Stalgard®
coated for maximum corrosion resistance. Wire ties
are available in Hotdip Galvanized After Fabrication or
Stainless Steel. |

Seven barrel lengths for various sheathing thickness:
- 5/8"
(for 1/2" & 5/8" gypsum
board)
- 1"
(for 1" insulation)
- 1
1/2" (for 1" insulation with
gypsum board)
- 2"
(for 2" insulation)
- 2
1/2" (for 2" insulation with
gypsum board)
- 3"
(for 2-1/2" insulation with gypsum
board)
- 3
1/2" (for 3" insulation with
gypsum board, or 2-1/2" of insulation
with two layers of gypsum board)
- Once
the barrel-screw is in place, the wire tie
is installed into the barrel. The loop in
the tie allows approximately 1-1/4" of
vertical adjustment above and 1-1/4"
below the barrel for placement in the brick
veneer mortar join

There
are three types of Brick Veneer wire ties,
the Triangle Tie, and Single Tie (See below
for Seismic Triangle Tie). Standard Tie lengths
are 3", 3-1/2", 4", and 5".
They are available in 3/16 diameter Mill Galvanized
Steel, Stainless Steel, and Hotdip Galvanized
After Fabrication.
A
16 gage Seismic Hook tab comes factory welded
to the Pos-I-Tie® Tie for holding masonry
reinforcement or pencil rod. Meets Seismic
Zone requirements.

- Uses consistent screw. The screw is provided
as a part of the POS-I-TIE® System.
- No inferior
screws can be substituted.
- Provides positive connections. Screw actually
penetrates gypsum board making Positive Lateral
Connection for transfer
of compression and tension loads to structural
backup.
- Enables speedy cost-saving installation. Only
one screw needs to be placed, not two.
- Corrosion Resistant. POS-I-TIE® seals the
hole it makes when it seats itself in the backup.
Barrel section is made of
ZAMAC 3, a 92% zinc. alloy. Screws are Zinc
electro plated, coated twice, and baked in STALGARD®.
- Differential Movement. Slotted Barrel allows
for movement due to temperature variations.
Tie design provides for allowable
ACI 530 code vertical adjustment.
- Pos-I-Tie® Screw can be used to attach
and secure the insulation to the backup.

- Use
a drill with a depth sensitive nose piece
or a variable clutch adjustment. The barrel
end of the POS-I-TIE® is placed into the
reusable chuck adapter.
- For
steel studs drill the POS-I-TIE® through
the gypsum board and into the metal stud.
- For
structural steel center punch prior to drilling.
(High tensile steel or very thick steel may
require pre-drilling a 3/16" (4.76 mm)
hole.)
- For
concrete, CMU, or brick use the sleeve tool with drill bit. Pre-drill a 3/16"
(4.76 mm) hole to a depth of 2" (51 mm).
- Slide
the sleeve tool over the drill bit
and insert the CMU/Comcrete Screw into the
chuck adapter. Torque screw into the pre-drilled
hole.
Reusable
chuck adapter and sleeve tool are available
from Heckmann |
