INVENTION DESCRIPTION
The Imenaon is called "Markings on butld'mg products"
The inve~ion relates to t1~ field of construction building products such as
dimez~ional
lumber arid steel stud tracks.
In frarnaig walls the current method of laying out stud locations is slow and
labor intensive.
The tradesperson will usually set two wood plates {2 by 4 or 2 by 6 wood
members of various
lengths) side by side on the floor, then hook a measuring tape on. ane end and
consecutively mark
the stud bcatioris, usually 16" or 24" intervals. He will then take a framing
square and pencil to
draw a line across both waad plates at each mark and draw an x on the side of
the Brie that the stud
should be placed. They lines and trmrks are then used for the assembly and the
securing of the
studs to the plates. Applying these standard repetitious marks by hand is time
consuming and
potential for errors.
A similar scenario occurs in the process of laying out the location of floor
joists (wood
rriembers that support the floor substrate), ceiling joists and trusses; where
a series of interval marks
are made on the trirruner joist (wood member perpendicular to the joists) and
the top of a wall plate.
The wood members (plates and joists) are manufactured to arid
un°precise length and
therefore also need to be trimmed to an exact stud module length when more
than orie plate length is
required end to end. This requires the tradesperson to measure the length to a
s#ud or joist module,
draw a litre and then cut the member.
It is the objective ofthis invention to provide a fast and e~aisy medwd for
trades-people to
install studs, joists and trusses during the course of construction without
the use of measuring
devices. The object of the ~vention is also to facilitate the process of
cutting a length of waod to an
exact stud or joist module length quickly and accurately, without the u~ of
measuring devices and

without distracting marks tl~t could allow the saw operator to err. The result
is Thieved by pre-
marking the building products with repetitious markings to indicate the
desired location of studs,
joists and trusses, and with the benefit that these markings can also be used
as a guide to cut the
product to the correct length. The benefit is a faster and labor saving me~od
of wall framing, floor
framing; and roof framing. Other inventions (patent no. CA 2038889) have
building products with
regular spaced markings for the purpose of cutting a product to the correct
length but do not have
the clarity required for the quick layout and installation of studs, joists
and trusses.
The invention is a pre-marked wood ~iIding product (commonly called 2 by 4, 2
by 6, 2 by
8, 2 by 10, or 2 by 12), having a plurality of elongate surfaces with at least
one elongate surface
having a plurality of markings indicating where the stud or joist shoull be
placed. Each marking
consists of two parallel Lines spaced apart approximately 1'/s" (3.8 ctn.) and
a pictogram between
these parallel lines such as, but not limited to a "+" or an '~c". The marking
also contains a numeral
which describes its location as a length measurement from one end of the
building product to the
center distance between the two parallel lines. The marking at the starting
end of the building
product will be ~ the width {approx. 3/" ( l.9ctn.)) of the typical it~ervat
marking The markings
parallel lines and the pictogram between ttx; tines may be solid, dotted or
dashed and may also be in
colour with some combinations described herein but not limited to these. The
markings are placed at
intervals of 12" 16" and 24" or combinations thereof
The building Product may also be descn'bed as a metal track commonly used in
steel stud
construction that is in the shape of a "U" having markings at regular
intervals as described above cm
at least one surface.
The wood building product described above may also be a enulti-stud or
oriented-strand or
wood laminated product where a number of pieces of wood are composed together
in such a way
that the end result is similar in proportions. '
All dimensions described above may also be descried in feet and inches or
m~tic
equivalents.
The markings applied to the buildiqg products eoull be produced using numerous
~thods
including but not limited to silk screen, ink stamp, inkjet technology, laser
print technology, laser
burning, etc.

edges 1 and end 3. The markings are placed at 16" and 24" intervals with one
colour for 16" interval
markings 6 and 8 and another colour for 24" interval markings 7 and another
colour for in#erval
markings that are common to both 5 and 9.
Fig. 2 illustrates a length of dimensior~I lumber with the markL~gs placed at
16" and 24"
imervals with the solid Iines used in the 16" intervals 11 and 13, and dashed
lines used in the 24"
interval marking 12, and combination of dashed and solid lines used in the
intervals markings 10, 12
and I4 that are common to both.

placed an the edge 1 of the product.
Fig 4 illustrates a length of dimensional lumber 1 and 2 with the rr~rkings
placed at 12" and
l 6" intervals with solid lines used in the 16" intervals 11 and 13, and
dashed lines are used in the
12" intervals I5, 12 and 16 and a combination of solid and dashed lines 10 and
14 are used for
intervals that are common to both

called steel stud
track} with markings placed at 16" and 24" intervals along the internal face
of the track.
Fig 6 illustrates the parts of a marking that placed at the starting end ofa
building product.
The single lute 17 shown dashed is located a distance of approx'~4" from the
end of the product. The
mark in this instance is %z of a "X" mark 18. The dimension numeral is 0"
which represents the
stetting point of the building product. ,

lines 20 are shown solid with the pictogram 21 between the parallel lines
shown as a "X". The
numeral 22 is shown as a dimension in feet and inches.
Fig 8 ilh~strates the parts of one oprion for a marking shown on figures 2
thru 5 where the
parallel lines 23 are shown dashed and the pictograms 24 between the lines are
shown as a dashed
"~-". The numeral 25 is shown as a dimension in feet and inches.
Fig. 9 illustrates the parts of one option for a marking shown on figsmes 2
thnt 5 where one
of the parallel lines 20 is shown solid and the other parallel line 23 is
shown dashed. The pictograms
