Support Clip Substructure

Using the Slimline Supportclip with an adjustable substructure 
the most common asked question by Architects is "do you have one"?

shows the back of a prepared tile with the Slimline Supportclip
epoxied into place and ready for erection .The fixing on this tile ( 600 mm
x 300 mm x 10 mm thick ) as shown is the 6 mm Trapezoid base plate ready to
be installed onto a 41 mm x 41 mm channel , but the trouble with this method
is that any correction in the vertical alignment of the face of the tile
installed is only possible by shimming OUTWARDS --thus it is limited to
rocked face or tool worked thin panels and not for polished or ceramics

 

 

 

shows the installed 41 mm x 41 mm x 2.5mm thick wall channel that
has been ERECTED for the installation of the 600 mm x 300 mm x 10 mm
ceramic panels to be used in the test

Whereas in the installation of the panels shown in photo 1 --- these
channel had to be installed perfectly plumb at 300 mm centers to
accommodate the Supportclips that were to fix onto them . On the
adjustable substructure in the following photo's, the panels are installed
onto the horizontal fully adjustable Aluminium channel

shows the vertical channel with the 12 mm Trapezoid base plates
with the 12 mm x 100 mm long shafts with the 6 mm x20 mm deep hole screw
loosely into place to accept the bottom channel to fix onto them . The
channel nuts securing them are 12 mm
shows the Aluminum channel ( 50 mm x 25 mm deep x 3 mm thick )
fixed with the 6mm pan headed screw fixed through it into the end of the
shaft .On the top of the channel can be seen the back washer ( 40 mm in
diameter ), which has an insulation this nylon washer on one side of it to
stop electrolysis between materials .This was also strengthens the front
channel where it fits to the Stainless Steel shaft

shows the first channel being installed level onto the two
shafts . At this point it is where you align for the right cavity you want
to work  to . The 41 mm deep channel allows you 35 mm adjustment inwards ,
so you are advised to start in relation to the plumb of the channel that you
have erected . The threads are fully adjustable inwards and outwards by
leaving the lock nuts loose till it exactly in place . To effect different
cavity widths , you can shorten the shaft .In this case the overall cavity
is 140 mm on the bottom and opens out to 150 mm on the top at 900 mm high

shows a look into the back section of the  channel after the
installation and locked into place ready to accept the Slimline Supportclip
to hold the bottom of the panel that is to be installed .The 12 mm shaft  is
installed so as to sit in the middle of the channel

shows the bottom horizontal channel with the Slimline Supportclip
fixings installed onto it . These clips are fitted so as the top of the
frame of the clip is level with the top of the channel and then the fitted
panel to go onto this clip will finish in about the middle of the channel,
as the position of the installation point is always 27 mm up from the bottom
of the panel being installed (set by the Supportclip cutter ) . It also
shows the horizontal channel to accommodate the top fixing of the first
piece of ceramic tile  in place . The position of the top of this panel is
the exact distance above the panel below + the joint width and in this case
, seeing the panels are 300 mm deep and the joint width is 3 mm = 303 mm .
The top of this channel can vary a little bit in vertical measurement
upwards when it is installed and it won't effect the placement of the
ceramic panel as it is primary  there to  screw the Supportclip base to ,
but the more accurate the better . When installing the vertical channels in
this case , they were 415 mm apart , so the horizontal channels were fixed
92.5 mm from each end with the 12 mm shafts on the 600 mm long pieces of
horizontal channel. The panels of ceramic were fixed onto the channel at 150
mm in from each end of the panel AND this then kept the fixing points of the
vertical channel fixing and the supportclip fixing points in a separate
alignment

secured to the horizontal channel through the top parts of
the Supportclip (predrill these holes prior to securing with
the 12 gauge screw )

shows the next row of Trapezoid bases ( 2 off )installed in
place ready to accept the next piece of  channel to secure the next piece of
ceramic tile to  . These vertical channel would be all installed prior to
the start of installation, to a layout to suit the panel lengths . The
horizontal channel would be installed in lengths to suit the project , but
both come in lengths of 6000 mm long . Placement of the vertical channel
would be relevant to the size of the panels and their weight , but there is
2 needed / panel .Loadings for the system are in accordance with the
loadings of the 12 mm StoneSub brackets minus the weight of the Aluminum
channel / lin meter

channel supporting and restraining the bottom panel in place

shows the first 2 panels of ceramic installed . The bottom one is
secured and the second one is in place to be screwed to the Aluminum channel
.It shows the slight variance in horizontal height the channel can be
installed at and still be in the right plane to accept fixing point of the
Slimline Supportclip onto it .The bottom fixing point on the panel is where
you install a silicone sealer in preference to an epoxy . This ensures
movement of the panels in extreme situations instead of fracture if all
rigidly held together

(4.5 mm ) to accept the countersunk screw to secure it to the channel

shows the cavity achieved =150 mm , which is made up of 10 mm
thick tile , 5 mm thick Slimline Supportclip , 3 mm thickness in horizontal
channel,89 mm for the  shaft and back plate to the face of the 41 mm
vertical channel =total of 150 mm . The panel weight for the 600 mm x 300 mm
x 10 mm thick panel is 5 kgs and the  channel weight is .4 kgs/ 600 mm long
piece , so the total loading is 2.7  kgs/ clip @shaft length of 75 mm

shows a clean view behind the channel and the fixing screw from
the Supportclip protruding .

The positioning of the adjustable 12 mm brackets onto the vertical
channel IS related to the size of the panels and the cavity they are
going to be installed at .

All of the panels would have their brackets installed prior to erection
--a time of 12- 15  hrs is needed to give epoxies time to cure .
5 minute epoxies are good but are down on strength in relation
to the 24 hr cure ones

The load of the 50 mm x 25 mm x 3 mm thick channel is
750 grams/ lin meter and this adds to the load on the brackets
supporting the panel--2 / panel. See chart for load capacity
of the shafts .

The cladding of the panels is covered by 2 separate sections --
the 12 mm shaft load strength and the Slimline Supportclip
carrying capacity when attached to the horizontal channel .

The wind load capacities are stated on the chart and if panels
are installed in situations above 10 mts high and a stated wind
pressure of 2.53 kPa is exceeded , then extra installation of
Supportclips are needed ---side fixings ( lateral clips )
are necessary .

The costing of the lightweight substructure / m2 when
installing 1200mm x 600 mm  x 9-12 mm thick Ceramic Panels
( up to 25 kgs) @a cavity of 60 mm --120 mm  cladding
area with a maximum loading/ clip of 13 kgs , using 
3 Supportclip fixings/ panel is $53.00/ panel =$76.00/ m2 .

The cost of of the lightweight substructure / m2 when
installing 1200mm x 1000mm x 15 mm thick panels
( 50 kgs) @ a cavity 50 mm- 70 mm cladding area with
a maximum loading/ clip of 17 kgs, using 3 Slimline
Supportclips/ panel and 2 side fixing  Supportclips/ panel =
$70.00/ 1.2M2 PANEL =$ 56.00/ m2
