Description
This invention relates to improvements in fire collars.
This invention has particular, but not exclusive, application
to locator plates for cast-in fire collars and whereby reference
will be made to same.
Fire collars are typically used for preventing fire spreading
L0 from one side of a wall or floor to the other side via a
penetration through which pipes, ducts or other service carriers
pass.
Possibly one of the more important uses of fire collars is with
L5 conduits, particularly pipes and ducts, which are formed from
plastics materials, such as PVC and HDPE, but they are also used
with rubber based materials, deformable metals and various
composite materials.
Most cast-in fire collars include a housing in which there is
formed a passage through which a conduit may extend and a layer
of intumescent material located within said passage and, when
in use, between the conduit and the housing. Some fire collars
also include actuation means capable of movement between a non
operating mode proximal, or attached, to the layer of
intumescent material to an operating mode whereby at least a
portion of the layer of intumescent material and/or the
actuation means at least partially obstructs the passage and the
conduit.
The housing typically includes a base, that is adapted to rest
on formwork, in which there is formed a first opening and an
opposing free end portion in which there is formed a second
cIG601233description2April2024 opening, that is substantially circular in shape, said base and said free end portion being spaced apart and connected by an intermediate side wall, such that said first and said second openings are coaxial and said side wall defines the passage connecting said first and second openings.
The base typically includes an outwardly directed peripheral
flange, and mounting means associated with said flange for
securing the base to the formwork, such as a plurality of
L0 mounting tabs or anchor points that are connected to the
peripheral flange by a frangible connection, said tabs or anchor
points being generally equally spaced around the periphery of
the flange, and whereby said tabs or anchor points each include
a mounting aperture formed therein through which a shank may
L5 extend of a nail that is used to secure the tab or anchor point
to the formwork.
In some embodiments the side wall of the housing defines the
second opening and whereby in use a cap may be provided so as
to selectively close said second opening and thereby prevent
concrete spilling into the passageway and interfering with the
actuation means.
Alternatively, the free end portion may include an inwardly
directed annular flange that defines the second opening and a
lip or guide that is connected to, and which extends away from,
the inner edge of said annular flange.
Some fire collars are also provided with a removable plug, or
pipe guide, that is adapted to close the first opening and
thereby in use inhibit concrete entering the passage via the
first opening and possibly interfering with the actuation means.
The pipe guide typically includes a base that is substantially
cIG601233description2April2024 flat and a centrally located mounting portion that is spaced above the pipe guide's base, said mounting portion having a centrally located mounting aperture through which a fixing may pass for securing the pipe guide to the formwork.
The pipe guide is secured to the base of the housing by the
frictional engagement of the base with the periphery of the pipe
guide.
L0 The pipe guide may also include locating means for supporting a
conduit in the passage such that the conduit and the first and
second openings are coaxial, such as a plurality of arcuate
protrusions that extend upwardly from the base and which are
arranged in a staggered arrangement in adjacent lanes such that
L5 they may support an end portion of a conduit that is located
therebetween, said mounting aperture and said lanes being
concentric.
Often the preferred position of the conduit will be marked on
the formwork by two intersecting orthogonal lines and whereby
the point at which the lines intersect shall coincide with the
preferred location of the axis of the conduit. Users are
required to position the fire collar at the preferred position.
Unfortunately, often it is difficult to accurately locate the
point of intersection of the lines drawn on the formwork with
the axis of the passage of the fire collar and whereby as a
consequence a conduit supported by the fire collar, and
subsequently cast in the concrete, may not line up with other
conduits to which it must be connected.
It is therefore an object of the present invention to provide
an improved pipe guide and/or locator plate for a fire collar
cIG601233description2April2024 which will alleviate some of the deficiencies of the prior art and which will be reliable and efficient in use.
With the foregoing and other objects in view, this invention
relates to a locator plate for a fire collar of the type having
a housing that includes a base in which there is formed a first
opening, and a second opening formed in said housing that is
spaced from said first opening by an intermediate side wall, and
whereby the first and the second openings are coaxial and are
L0 connected by a passage that is located between the first and
second openings, said locator plate being adapted to selectively
close the first opening, said locator plate including:
a base having a predetermined peripheral boundary,
a predetermined point of reference that is contained within
L5 said peripheral boundary;
positioning means for positioning the first opening of the
fire collar in a preferred position relative to said locator
plate such that said point of reference and the first opening
are coaxial;
a first alignment means marked on, applied to, or formed
in said base, said first alignment means being aligned with said
point of reference;
a second alignment means marked on, applied to, or formed
in said base, said second alignment means being aligned with
said point of reference, whereby an imaginary first line
connecting said first alignment means to said point of reference
is substantially orthogonal to an imaginary second line
connecting said second alignment means to said point of
reference;
whereby in use said base may be placed on formwork on which
there is drawn two intersecting orthogonal lines, such that a
portion of one line is aligned with said first alignment means
while the other line is aligned with said second alignment means,
cIG601233description2April2024 and whereby the point at which the two lines intersect and said point of reference are coaxial.
The first and second alignment means may include alignment
means, such as a notch, protrusion or marking, associated with
the peripheral boundary.
The base may also include a window formed in said base that is
adapted to cooperate with the first and second alignment means
L0 so that in use said base may be placed on formwork on which
there is drawn two intersecting orthogonal lines, such that a
portion of each line can be seen through said window and whereby
one of said lines is aligned with said first alignment means
while the other line is aligned with said second alignment means,
L5 and whereby the point at which the two lines intersect and said
point of reference are coaxial. For example, the window may
include one or more discrete window portions.
Preferably the locator plate includes mounting means for
securing the locator plate to formwork, such as one or more
mounting apertures. For example, the point of reference may be
the centre of an aperture formed in the base and wherein a shank
of a fastener that is used to secure the locator plate to
formwork may, in use, may extend therethrough.
In another aspect, this invention relates to a locator plate for
a fire collar of the type having a housing that includes a base
in which there is formed a first opening, and a second opening
formed in said housing that is spaced from said first opening
by an intermediate side wall, and whereby the first and the
second openings are coaxial, said locator plate being adapted
to selectively close the first opening, said locator plate
including:
cIG601233description2April2024 a base, an aperture formed in said base; positioning means for positioning the first opening of the fire collar in a preferred position relative to said locator plate such that said aperture and the first opening are coaxial; a first alignment means marked on, applied to, or formed in said base, said first alignment means being aligned with the centre of said aperture; a second alignment means marked on, applied to, or formed L0 in said base, said second alignment means being aligned with the centre of said aperture, whereby an imaginary first line connecting said first alignment means to the centre of said aperture is substantially orthogonal to an imaginary second line connecting said second alignment means to said centre of said L5 aperture, and whereby in use said base may be placed on formwork on which there is drawn two intersecting orthogonal lines, such that one of the lines is aligned with said first alignment means while the other line is aligned with said second alignment means, and whereby the point at which the two lines intersect and the centre of said aperture are coaxial.
In another aspect, this invention relates to a locator plate for a fire collar of the type having a housing that includes a base in which there is formed a first opening, and a second opening formed in said housing that is spaced from said first opening by an intermediate side wall, and whereby the first and the second openings are coaxial and are connected by a passage that is located between the first and second openings, said locator plate being adapted to selectively close the first opening, said locator plate including: a base, an aperture formed in said base;
cIG601233description2April2024 positioning means for positioning the first opening of the fire collar in a preferred position relative to said locator plate such that said aperture and the first opening are coaxial; a first alignment means marked on, applied to, or formed in said base, said first alignment means being aligned with the centre of said aperture; a second alignment means marked on, applied to, or formed in said base, said second alignment means being aligned with the centre of said aperture, whereby an imaginary first line

L5 window portion that is located adjacent said first alignment
means and a second window portion that is located adjacent said
second alignment means, whereby in use said base may be placed
on formwork on which there is drawn two intersecting orthogonal
lines, such that a portion of each line can be seen through a
respective window portion and whereby one of said lines is
aligned with said first alignment means while the other line is
aligned with said second alignment means, and whereby the point
at which the two lines intersect and the centre of said aperture
are coaxial.
The first and second alignment means may include a mark,
protrusion, notch or such like that is applied to, extends
upwardly from, or is formed in the base, such as a peripheral
edge portion of the base.
Preferably both the first and second alignment means each
include opposing alignment portions with the aperture located
cIG601233description2April2024 therebetween, such as marks, protrusions or notches associated with opposing portions of the base.
Preferably the first and second alignment means and the first
and second window portions all lie in the same plane. Further,
it is preferred that the portion of the base in which the first
and second window portions are formed abuts against the form
work so as to reduce any parallax errors that may occur when
aligning the first and second alignment means with the
L0 respective lines drawn on the formwork.
The alignment means preferably resembles a line and whereby the
line may be may painted on the base; a groove formed in the
base; a rib that extends upwardly from the base, or a slit or
L5 slot in the base.
The line may extend from at least one portion of the adjacent
window portion in the general direction towards or away from the
centre of the aperture. However, preferably the window portion
is located between opposing portions of the line.
The aperture may be of a suitable size that it may be used as a
mounting aperture through which a suitable fastener that is used
to secure the locator plate to the formwork may extend. For
example, in use, a shank of a nail may extend through the
aperture.
The positioning means may include one or more markings located
on the base of the locator plate which show where the base of
the fire collar should be positioned thereon.
Alternatively, the positioning means may be adapted to engage
the fire collar. For example, the positioning means may include
cIG601233description2April2024 a continuous cylindrical wall, or a plurality of ribs, extending upwardly from the base and having at least one face that shall abut against an internal face of the passage in the fire collar adjacent the first opening.
Preferably the peripheral shape of the locator plate and the
shape of the first opening formed in the housing are
complimentary. Preferably the locator plate and the passage
adjacent the first opening in the housing form a close fit.
Further, the locator plate may include engagement means for
maintaining the locator plate in engagement with an internal
face or faces of the passage. For example, the engagement means
may include one or more mechanical fasteners. Alternatively,

protrude outwardly from one or more faces that define the
periphery of the locator plate.
Preferably the locator plate also includes locating means for
locating a conduit on said locator plate such that the axis of
the conduit and the centre of the aperture are coaxial. For
example, the locating means may include a continuous cylindrical
wall having a face that shall abut against either an internal
or external curved face of the conduit. Alternatively, the
locating means may include a plurality of arcuate protrusions
that extend upwardly from the base and which are arranged in a
staggered arrangement in adjacent concentric lanes such that
they may support an end portion of a conduit that is located
therebetween.
The locator plate may also include mounting means, or additional
mounting means, for securing the locator plate to formwork, such
as a plurality of mounting apertures formed in the locator plate.
cIG601233description2April2024
For example, these mounting apertures may be formed in the
protrusions that extend upwardly from the base that form part
of the locating means.
Preferably in use, the point of intersection in the centre of
the aperture is used to nail or secure the locator plate to the
formwork. The housing can then be placed over the locator plate
such that the locator plate is received snugly within the first
opening, and whereby the housing may then be secured to the
L0 formwork by nails extending through mounting apertures or
mounting tabs associated therewith.
In another aspect, this invention relates to a locator plate for

L5
The inner raised portion 151 is further separated from the
central by a step 170 having a substantially flat top face 171
and a continuous side wall 172.
The base 111 is adapted to engage a complementary shaped first
opening of a fire collar and whereby the base, when secured to
formwork, may be used to maintain the fire collar in a preferred
location while concrete is poured around the fire collar and
provide support for a conduit that extends through the passage.
In use, the intersection of two orthogonal lines drawn on
formwork to be used to support a concrete wall, such as a floor
or ceiling, during its construction is used to indicate the
predetermined location of the longitudinal axis of a conduit
within the intended wall as well as the location of a fire collar
to be cast in the concrete, said fire collar to be used in the
event of a fire to close the conduit and prevent the fire
cIG601233description2April2024 spreading from one side of the wall to the other side of the wall through penetration.
In order to secure the fire collar temporarily to the formwork,
the locator plate 10 is first placed on the formwork with the
top wall 27 facing up, or uppermost, such that portions of the
two orthogonal lines can be seen through the four window portions
31. The locator plate 10 is then moved relative to the formwork
until the first orthogonal line is aligned with the two ribs 36
L0 and the second orthogonal line is aligned with the two ribs 41,
at which point the longitudinal axis 29 of the mounting aperture
28 is aligned with the point of intersection of the two
orthogonal lines.
L5 A nail or a faster having a threaded free end portion which
extends through the mounting aperture 28 so as to engage the
formwork is then used to secure the locator plate to the
formwork. Alternatively, or in addition to this single
fastener, one or more nails or threaded fasteners extending
through respective mounting apertures 55 may be used to further
secure the locator plate 10 to the formwork.
The housing of the fire collar is then placed over the locator
plate 10 such that the locator plate fits snugly within the
first opening and is retained in this position by clips having
a free end portion that are adapted to engage a respective one
of the recesses 17.
The base of the fire collar may include an outwardly directed
flange having a plurality of mounting tabs frangibly connected
thereto and whereby the mounting tabs are also secured to the
formwork using suitable nails or threaded fasteners.
cIG601233description2April2024
A free end portion of a conduit may in turn be placed within the
passage and retained therein by the frictional location of the
conduit's side wall against opposing continuous side walls 53
and 57.
After the concrete is poured, it is anticipated that some
concrete may seep under the locator plate and become trapped
within the confines of the inverted channels of the intermediate
mounting portion 50 and the outer raised portion 51.
L0
The second locator plate 110, like the locator plate 10, may be
used to locate a fire collar in a preferred position on
supporting formwork and wherein a free end portion of a conduit
may be placed within the passage of the fire collar and retained
L5 therein by the frictional location of the conduit's side wall
against opposing continuous side walls 153, 157 and 172.
Alternatively, the end portion of the conduit may rest on the
top face 171 of the step 170 and wherein a side wall of the
conduit shall bear against the side wall 157. Alternatively the
end portion of the conduit may rest on the top face 127 of the
central mounting portion 127 and wherein a side wall of the
conduit shall bear against the side wall 172 of the step 170.
It will be appreciated that the invention will enable users to
more accurately position a conduit within a concrete wall, such
as a floor or ceiling.
It will of course be realised that while the foregoing
description has been given by way of example of the invention,
all other modifications and variations thereto as would be
apparent to a person skilled in the art are deemed to fall within
cIG601233description2April2024 the broad scope and ambit of this invention as hereinbefore defined in the appended claims.
