Installation guidelines for a welded wall tie on a beam
The welded wall tie is 6 7/8" (17,5 cm) long and should protrude from
the beam by a maximum of 3 7/8" (10 cm), as shown in fi g. 5.46.
Installation of the re-usable
wall tie
2" (5 cm) weld bead
3" (5 cm) weld bead
Maximum length
of 3 7/8" (10 cm)
Wall tie welded to beam
Installation guidelines for fi xed wall ties
Fixed wall ties can be installed on a wall between two
layers of brick (fi g. 5.43). It is important to make sure that
several layers of brick have been laid on top of the fi xed
wall ties and that the mortar has cured properly
before
attaching mast ties to the wall ties
.
Distance between the anchoring structure and the back
of the brick wall must not be greater than 1 1/2" (3,8 cm),
as show in fi g. 5.44.
Installation guidelines for a re-usable wall tie
Used mainly for masonry work projects, the re-usable wall tie is
installed in a cavity left unfi lled in a brick wall under construction.
When dismantling the setup and removing mast ties, the re-usable
wall tie is removed and the brickwork is completed.
Maximum distance
1 1/2" (3,8 cm)
Anchoring System
The welded wall tie can be fastened to the
beam by three 3/16" (5 mm) wide weld beads.
The two weld beads along the length of the
wall tie will be 3" (5 cm) long, while the weld
bead along the width of the wall tie will be
2" (5 cm) long.
Installation guidelines for fl oor ties
Floor anchoring can be installed at angles ranging from 0
°
up to 30
°
from horizontal. Floor
ties must be able to sustain 1500 lb (680 kg) of tension/compression and 3000 lb (1361 kg)
of shear force.
