Description
TECHNICAL FIELD
[0001] This invention relates to the building industry. In
particular, this invention relates to improved forms of stud for
use in building.
BACKGROUND ART
[0002] Traditionally, studs for use in building have been
constructed in rigid sections. These may have various cross
sections, some of the best known in current use being the "C"
section and the "dog bone" stud.
DISCLOSURE OF THE INVENTION
[0003] This invention is predicated upon the discovery that there
are substantial advantages to be gained if a stud is adjustable in
a vertical or horizontal direction.
[0004] Accordingly, in one form, this invention provides a stud of
chosen length, the stud having a plurality of sections, each
extending for substantially the length of the stud, characterised
in that one section is moveable in relation to the other section or
another of the sections in a direction parallel to the length of
the stud, further characterised in that each section has a
longitudinal edge terminating in a U- or V-shaped web and the
sections are adapted to connect by mating a U- or V-shaped web of
one of the sections with a U- or V-shaped web of the other section
or another of the sections, and further characterised in that the
stud includes one or more hollow sections, each being of constant
cross-section throughout the length of the stud. In one embodiment,
the stud has two or more sections, which are adapted to be moveable
one relative to the other so that the stud is adjustable as to
height.
[0005] In another form of the invention, the stud has two or more
sections which are moveable one relative to the other so that the
stud is adjustable horizontally and consequently can vary in
thickness. Preferably, the stud is made of first and second
sections, being slideable relative to one another.
[0006] While the start of the invention may have any desired number
of sections, it is especially preferred that the stud has two or
four sections.
[0007] In yet a further form, the stud of the invention is a
two-part stud in which one part is adapted to intersect with the
other to form the stud.
[0008] The invention also provides a stud section for use in
forming the stud of the invention in its various forms.
[0009] The improved stud of the present invention may be made of
any suitable material, including metal or fibre reinforced
cement.
[0010] In the case of the stud of the invention which is adjustable
as to height or width, it is contemplated that once the stud is
adjusted in the appropriate dimension, either vertically or
horizontally, the stud is fixed in position by fixing means. This
may be achieved, for example, by fixing one section of the stud to
another by various methods. One of these methods is to screw one
part of the stud to another. Another is to employ an expanding
locking mechanism. A third is to use a ratchet arrangement.
Examples of all three will be described in connection with the
drawings, below.
[0011] It will be appreciated that the ability to adjust a stud
vertically, especially by sliding one section of a two part stud
relative to the other, can have decided advantages in building. For
example, in the construction of a typical wall made of panels
attached to the stud, a panel may be attached to one section of the
stud on one side and a second panel attached to the other section
of the stud on the other side, the sections of the stud being
slideable relative to each other. The panels may thus be raised or
lowered to provide a gap for access to cabling and other services
within the wall,
[0012] Similarly, where stud is adjustable horizontally, this can
be used to create a gap between panels through which access can be
gained to the stud, for example to hang furniture or work stations
from the stud.
[0013] The fixing means may also include clips. Further, remote
fixing technology may be used and in this regard the contents of
International patent specification No. PCT/AU99/00185 are imported
herein by reference.
BRIEF DESCRIPTION OF THE DRAWINGS

an "X" stud is formed from intersecting portions;
[0027] FIG. 31 shows in plan view how the sections in FIG. 26, for
example, can be cut from a single sheet of fibre reinforced cement;
and
[0028] FIGS. 32 to 36 show in perspective view parts of further
embodiments of improved studs according to the invention.
BEST MODES FOR CARRYING OUT THE INVENTION
[0029] It will be noted that in the embodiments in FIGS. 3 and 4,
stud 10 has a first section 12 and a second section 14 which mate
through a suitable connection such as U-shaped webs 16 and 17 and
which can slide relative to one another in a vertical direction, as
shown by arrow 15.
[0030] Panels, such as panel 18 in FIG. 5 and tracks such as top
track 20 in FIGS. 5 and 6 may be attached to the stud of the
invention by any suitable fastening system, including remote
fastening as described in International patent application No.
PCT/AU99/00185.
[0031] As can be seen from FIG. 7, the stud of the invention may
include apertures 22 (refer also FIGS. 5 and 6) or spikes 24, which
can be used to fix a panel or other element to the stud. Stud 10 in
FIGS. 7 and 8 has four sections 11, 12, 13 and 14, each of which is
identical. Each section has at each of its longitudinal edges a
U-shaped web 16 or 17 which can mate with web 17 or 16 respectively
on an adjoining section.
[0032] The sections of stud 10 may be locked together in various
ways, for example as shown in FIGS. 9 to 11. For example, FIG. 9
shows a pierced type of fixing wherein a nail or screw is inserted
through two U-shaped webs 16 and 17 or web 16 is glued to web
17.
[0033] As an alternative, and as illustrated in FIG. 10, an
expanding locking mechanism 30 may be used to lock web 16 and 17
together. Once mechanism 30 expands, webs 16 and 17 will lock onto
each other due to friction. The mechanism 30 may consist of a
continuous strip inserted in channel 26 or a series of strips.
[0034] FIG. 11 shows how panels 18 may be fixed to sections 12 and
13 by any suitable means and result in a decorative feature, in
this case, a recessed shadow line 28. It is noted that furniture or
decorations may be attached to the stud by using this shadow line
28, without damaging the panels 18. Any holes that are drilled into
the shadow line 28 will be more difficult to see than if they were
drilled though the panels 18.
[0035] The stud sections may lock together by means of a ratchet
mechanism in the version illustrated in FIGS. 12 to 21. As shown in
FIGS. 12 and 15, stud 10 is made of two sections, 32 and 34.
Section 32 is illustrated in FIGS. 12 to 16, with section 34 in
dotted outline in FIG. 15. Section 34 is illustrated in FIGS. 17 to
21, with section 32 in dotted outline in FIG. 20. Section 32 has
V-shaped webs 36 and 38, in each of which has a series of
apertures, 40.
[0036] Similarly, as shown in FIGS. 17 to 21, section 34 has
V-shaped webs 42 and 44, each of which includes protrusions 46
adapted to mesh with apertures 40 in a ratchet manner, as
illustrated in FIG. 21.
[0037] In FIG. 22, the symbol x indicates the position at which
protrusion 46 is fully engaged in aperture 40. The symbol o
indicates locations of partial engagement. The left hand side of
FIG. 22 represents spacing at 20 mm, while the right hand side
represents spacing at 18 mm.
[0038] As shown in FIG. 22, when the ratchet spacing is chosen
appropriately, the sections 32 and 34 of the stud 10 may engage in
five places over the space of one meter or eleven places over the
space of two meters. In addition, there will be a partial lock at
every two millimetre interval in the illustration shown.
[0039] It is to be appreciated that the ratchet mechanism can be
used on a wide variety of stud designs.
[0040] As earlier indicated, it is within the scope of the
invention that the stud can be adjustable horizontally. One
embodiment of this version of the invention is shown in FIGS. 23 to
25, where the stud is made of two portions, 50 and 52, which are
triangular in cross-section. When portion 52 is adjusted relative
to portion 50, for example as shown in FIG. 25, the stud can
increase in thickness and be used where it is desired to space wall
panels further apart. Of course, the stud in FIGS. 23 to 25 may
also be adjustable vertically.
[0041] The stud in FIGS. 26 to 31 is particularly suitable for
manufacture from a fibre reinforced cement (FRC) sheet (refer FIG.
31). After the portions 51 and 53 have been cut from the sheet, and
unwanted sections 54 and 56 have been removed, portion 51 can be
mated with portion 53 as shown in FIG. 27 to form an "X" stud, as
shown in FIG. 28. Especially when this type of stud is used to
connect FRC panels, the resulting structure is homogenous. Thus
panels will have the same capability of expansion and contraction
as the stud.
[0042] The stud of FIGS. 28 to 30 is also illustrated in FIG. 34
and a further variation in shown in FIG. 35 where the stud is
enclosed in a box. This box, and the studs in FIGS. 32 and 33 as
well the elements found in FIG. 36, may be constructed from a web
made of suitable material, such as fibre reinforced cement. The
sections of the web may be hinged together by using paper tape
hinges or polysulphide type hinges or clip hinges, for example.
[0043] It will be readily apparent to one skilled in the art that
the various improved studs described above represent significant
steps forward in the art. It will be especially appreciated that
studs made of the same material as the panels or elements which are
to be attached to them can have decided advantages over
conventional systems.
[0044] The scope of this invention is not limited by the
embodiments described above. Various modifications may be made
without departing from the spirit of the invention.
Industrial Applicability
[0045] The invention represents a significant step forward in the
technology relating to studs used in the building industry and is
capable of producing studs at a low cost, as well as having
flexibility in relation to movement horizontally and
vertically.
