"TIE SUPPORT SYSTEM FOR MASONRY VENEER''
BACKGROUND OF THE INVENTION
This invention relates to new and useful
improvements in tie support systems for use with masonry
veneer of brick, stone, or other such materials.
Conventionally, either insulation or sheathing
is applied to the faces of vertically situated spaced and
parallel studs and the veneer is then supported by means
of ties which are applied on top of the insulation or
sheathing to the studs therebehind. These conventional
supports normally compress the insulation or shea-thing
when installed in order to give sufficient support to the
facing material and this often allows moisture to
penetrate with subsequent distortion or cracking of the
veneer and in general, are unsatisfactory in use.
The present invention overcomes these disadvan-
tages by providing a tie support device which includes a
plurality of legs extending from a tie support surface.
These legs are adapted to pierce the insulation or
sheathing and are of a depth such that the pointed ends
of the legs engage the face o~ the stud with the tie
support sur~ace engaging the outer face of the insulation
or sheathing. These devices are secured to the studs

without any compression of the insulation or sheathing
yet at the same time spread and transfer the load
directly, via the tie, from the masonry veneer to the
studs behind the insulation or sheathing.
SUMMARY OF THE I~ENTION
One aspect of the invention is to provide a tie
support device comprising in combination a main channel
portion having a base flange and a pair of side flanges,
one on each longitudinal side edge of said base flange
and extending substantially at right angles to the pîane
thereof, s~ud face engaging legs extending from adjacent
each end of said main channel portion, ~he depth of said
legs being substantially similar to the thickness of ~he
sheathing or insulation through which said legs extend
and means on said hase fla.nge of said channel portion to
detachably secure a veneer support tie.
Another aspect of the invention is to provide a
blank for forming a tie support device in which the side
of said leg adjacent the end of said channel extends
substantially perpendicular from the longitudinal axis of
said base flange, the other side edge inclining outwardly
from said base Flange toward said pointed end.
Another aspect of the invention is to provide a
device of the character herewithin described which is
33~
extremely simple in construction, economical in manu-
facture and otherwise well suited to the purpose for
which it is designed.
With the foregoing in view, and other advan-
tages as will become apparent to those skilled in the art
to which this invention relates as this specification
proceeds, the invention is herein described by reference
to the accompanying drawings forming a part hereof, which
includes a description of the best mode known to the
applicant and o~ ~he preferred typical embodiment of the
principles of the present invention, in which:

DETAILED DESCRIPTION
-
Conventionally, brick veneer ties used in
conjunction with insulation or exterior sheathing utilize
screws to secure the devices to the back-up system such
as studs. However, they both have to be installed prior
to the installation of the insulation or sheathing which
of course can interfere with the construction sequence
and because of their size and metal contact continuity,
their use often can reduce the thermal efficiency.
The present invention overcomes both of these
disadvantages and reference should first be made to
Figure l which shows a blank used to form the tie sup-
port. It is preferably stamped out from galvanized metal
of the required gauge depending upon design parameters.
16 and 18 gauge material are useable in the majority of
instances.
The blank consists of a substantially elongated
rectangular central portion lO having triangular legs 11
extending from adjacent the ends 12 of the central
portion. These legs include a side 13 extending perpen-
dicular to the longitudinal axis 14 of the central
portion lO, and an inner side 15 which inclines outwardly
from the longitudinal side edges 16 of the blank, ter-
~2S:~336
minating in a pointed distal end 17 where it joins theedge 13 as clearly shown.
Bend or fold lines 1~3 extend from one end to
the other of the central portion of the blank and are
inboard of the longitudinal side edges 16 thereof as
clearly shown in phantom in Figure 1 thus enabling the
outboard portions of the central portion 10 ~ogether with
the legs 11, to be b~nt at right angles to the plane of
the central portion 10 so that the two pairs of legs lie
spaced and parallel from one another as cle~rly shown in
Figur0 2 and the outboard portions of the cen~ral portion
form, together with the central portion, a channel con-
figuration. These outboard portions are indicated by
reference character 19.
This channel configuration gives the necessary
strength to the tie support and acts as a load trans-
ferring device together with the legs 11. Apertures 20
are formed through the central portion ].0 along the
longitudinal axis 14 thereof.
Figures 3, 4 and 5 show the supports installed.
Reference character 21 shows a vertical steel stud having
an inner flange 22 and an outer flange 23 with insulation
2~ being situated between the flanges and against the web
25.

Rigid insulation or ~he l.ike 26 is installed
against the faces 27 and extends between adjacent studs
in the usual way and the tie supports are then engaged
upon the outer face 28 of the insulation and pushed
inwardly so that the legs 11 pierce through the insula-
tion facilitated by the pointed ends 17 thereof. The
length of the legs is substantially equal to the thick-
ness of the insulation 26 so that when installed as shown
in Figure 3, the pointed ends 17 of the legs engage the
face 27 of the studs and the flanges 19 pierce the
insulation slightly so that the inner face 29 of the
channel is in inter-facial contact with the outer surface
28 of the insulation as clearly shown.
In Figure 3, a corrugated strip tie 30 is
secured to the device by means of a self-tapping screw 31
which engages the inner end portion 32 of the tie, the
central aperture 20 of the support and the flange 23 oF
the channel-shaped stud, whereupon the veneer facing 33
may be constructed with the ties engaging the mortar
joints 34. It will be noted that an air space 35 i5 left
between the inner side 36 of the masonry veneer and the
outer face 28 of the insulation thus increasing the
insulating value of the construction and minimizing the
heat transfer through the metal contact of the veneer
~L~5~33~i
support sys~em. The load is transferred through the legs
to the face of the stud 21 without any compression
occurring to the insulation sheet 26.
In Figure 4, an alternative tie assembly is
shown with the tie 37 being adjustably secured around a
vertically situated clip 38 which in ~urn is secured to
the tie support by means of two self-tapping screws 31
securing same to the device and to the stud by the upper
and lower apertures 20 as clearly shown.
Figure 5 shows an adjustable continuous ~rick
joint reinforcement in which the tie 39 is secured ~o the
device similarly to that shown and described in Figure 4
and then ~his ~ie in turn is secured to a longitudinally
extending tie bar 40 which extends through the mortar
joints of adjacent veneer bricXs 41 clearly shown.
In all cases, the load is transferred directly
to the face of the studs by means of the legs and of
course the attaching self-tapping screws 31 without any
damage occurring to the insulation or sheathing attached
to the face o~ the studs.
It would therefore be seen that the invention
provide support ~o the metal ties used to transfer loads
from masonry veneer to the metal stub backup systems.
The ties are designed utilizing the air space between the
~5~33~
masonry veneer and the semi-rigid or rigid insulation
always provided of course that the capacity of the
devices and the backup system is not exceeded.
Since various modifications can be made in my
invention as hereinabove described, and many apparently
widely different embodiments of same made within ~he
spirit and scope of the claims without depar~ing from
such spirit and scope, it is intended that all matter
contained in the accompanying specification shall be
interpreted as illustrative only and not in a limiting
sense~
