G'day and Welcome back to the YouTube channel
in today's video or what I want to show you is the major components of
a component
Scaffold system
so I'm going to start at the bottom and with my lay up and
obviously on the ground
We've down what we call sole plates
sole boards
Basically, they're just timber board
that the rest of scaffold sits on, helps to distribute the weight of the scaffold across the ground now and
I originally did my scaffolding course
We were taught to use one sole plate under each
leg of the Scaffold if you like
However since doing my course I have have been pulled up by Workcover, which is the local
WHS authority in Australia, New South Wales and
they actually wanted
the sole plates to extend
across the width of the Scaffold, so
This is the way I do it now obviously if you had very very unlevel ground
that would be extremely hard to do so anyway the lowest member should be your
Sole plates and they sit on the on the dirt just to level the ground up give you a firm base
Directly on top of your sole plates go your your screw jacks. So these are adjustable this handle here
lines up and down a threaded shaft
You can see there are holes in sole plates, so they can be
sorry there are holes in the base of the adjustable Screw Jack
So you can nail them or screw them down to the sole plate, so they're not going to move around
next member is
the
Standards these are the vertical members
They come in different lengths, and they should all be
staggered throughout the scaffold so that you don't get the join in the scaffold or the same level, so
you can stagger them around at different lengths especially going to a reasonable height
a feature of the Standard
they have, on this particular type, which is the quick stage type, has these four cluster or this cluster of four
connectors
You'll see two higher than the others that become important later
And of course it has a socket on the end so you can insert the next standard into the top of that one
So they're your standards
Next member I'm going to look at is your Transom
Transoms go across the width of the scaffold and in this particular scaffolding system the planks sit into the transoms
So there are T-shape
They fit into these sockets with the wedge the transom has to go into the lower
socket not the high one and I'll show you why later
so transom always goes into the lower of the two sockets and you can see this
T-shaped give somewhere for the planks to sit
So they're the transoms they go across the width of the Scaffold
You then have your leadgers they
go across the length so L= leadger or L = length if you want to try and remember of a way of remembering the name
again they fit in with the wedge system into the socket and they go into the top socket obviously and
They tie the scaffold together that way
We've always got bracing these are longitudinal braces because again they go the length of the Scaffold
Okay, and they fit one bay each so each
four standards form what we call a bay of
Scaffold
okay, so one longitudinal brace per Bay and
if you had a very long scaffold every fourth
Bay would have to have a longitudinal brace on it, and they zigzag up as you get higher
So they're the longitudinal braces
They have a swivel end on them, so this end is adjustable it swivels around to whatever angle you need
locks in
Same as everything else
On the ends we have our transverse braces, so they are cross the width of the Scaffold
Okay, and you can either have them all going the same direction like that, or you could have them zigzagging up the end
So remember that longitudinal Brace transverse brakes
Okay, then down here. We've got what we call the hop up brackets
So these come in different widths
this one's a 2
2 plank bracket because two planks will fit on it and our working minimum working platform is two planks
so it just wedges in on the top here and the bottom just sits against the standard and to stop them swinging around
We put in between them
what they call a tie bar
so it just stops the 2 hop up buckets from separating and
They go together like that
up here where this is going to be a Ladder Bay and
I've got a what they call a
Putlog transom in here
so it's a transom because it goes across the width of the Scaffold and
It's a Putlog because it just slips in or is inserted around the bar
And there's generally a bolt to bolt this into place what this does it lets us put short planks
Into this part here which looks like our normal transom
So we can put a couple of short planks in there to form an opening in here and then our full planks will run through
So that our entire bay is not left open just the spot where the ladder comes through so that is a Putlog transom
There's all our planks in place you can see a couple of short ones there without that Putloged
This is a 5 Bay or 5 plank wide Scaffold
5 planks across the Bay you can get three
Generally 3 and 5 are the most common ones
so you can see there are 5 planks and
On our hop-ups, 2 planks on a hop ups to give them to give us our minimum working platform of 450mm Wide
Toe boards
so generally the scaffold setup the toe board with just the normal planks that we use and
There's enough room in the bay to set one on edge at the end for here and here
if you have now
1200 planks you can use them across the end they need to be wired into place or using the special
Toe board clips, you can secure them into place, they can't just sit there and
for special areas that are short you may have to use timber planks
But you need to have a toe board all the way around at least 150mm up if you can't you
can't clip them into place they need to be wired into place with some tie wire so they don't want to fall off
For special areas that they don't have standard components that won't fit. We can use Tube and Fitting so obviously
We have the Tube which is the pipe and the fitting which is this little?
attachment here notice that it's
Fixed so that when this bolt comes undone
And it was to sort of open up the pipe would not actually fall to the ground it would still be left in the fitting
So you should always keep the bolts on the upper side of those
And that just gives us a bit of flexibility in our Scaffold
and that's it there are the main components of
the Scaffold there obviously we need to have our ladder in and it needs to be tied top and
Bottom so that it's not going to slip
and
Just if you have a large gap
That you need to bridge you can use timber planks on the metal planks can't use metal on metal
You have to use timber planks across
To give you a safe each
And that's it. They're the major components of our Scaffold.
