WEEK 10 ACTIVITY: ‘DETAILING VOLUME’ (PART TWO)
This is the finalised
looking after the formwork
has been done.
These are the steel
reinforcers.
The retaining wall will
come up 100 meters
high.
Plywood
LBL member
reinforcements
To make in-situ concrete slabs, formwork is the very important part. Firstly, Workers constructed
reinforcements at the area where concrete need to be constructed. Then a box-like formwork is
made by using plywood and LBL members around the reinforcements and concrete will be poured
into the box. When the concrete is stable, the plywood and LBL members will be removed and the
reinforcements will stay inside the concrete. LBL members are similar to ply and can be used for
different veneers. They are cheap, resistant and light.
This pipe keeps water away and
will be put below the ground level.
The main part of the
building is constructed as a
frame structure with 4 main
load-bearing timber
columns. It is a combination
of timber and steel but
timbers are actually the
structural elements. The
roof part is an irregular
shape popping up. The blue
part is the sarking
insulation. Tough glasses
will be attached to the steel
frames to form the facade
on this side of the building.
Temporary Bracings
On the side of the building, the tallest part of the building are constructing by wall cladding. The
timbers are designed with tongue and slot so that pieces of timbers can be connected nice and tight.
Screws are also used to fix the timbers but they are hidden beneath the timbers.
The push props are holding the beam because the member is so heavy and still is not bolted well
yet. These props can be pushed up the satisfied height and supporting members that are not stable
enough. For example, in-situ concrete slab is made in the same way as well. As the formwork is
the work that shaping the slab, props are the things that supporting the formwork’s boxes of the
slabs. For concrete, it takes 28 days to be totally done. The props will be eventually removed when
everything is stable. The wood studs is one of the main elements in timber frame structure. They
protect timber beams from bending and breaking.
Wall Cladding
Wood studs
Push Props
Here is making the formwork for an in-situ wall. There are bracings supporting the formwork. The
black membrane are there to direct water.
Other than these picture. There are also some other important elements such as the cross bracing
used for reinforcing the walls. Cross bracing stop the wall from swaying. There are both ply
bracing and rod bracing. For rod bracing, two rods on diagonal positions having one end fixed by
nuts to the corner are pulled and connected together on the other ends. This method saves both
materials and money. In addition, there are some missing information about bar chairs and so on.
The site manager showed us how the framing
system is constructed. This looks like the Triple
Beam System (Ching, 2008, p.4.15). The members
such as steel beams are the long-spanning
members. The Z shape purlins are the primary
beams and the battens are the secondary beams.
Then insulation and roof will be built on top of
them. He mentioned that Z shape purlins are
chosen due to the long spanning of the buildings.
Instead of C shape purlins, Z shape purlins can lap
on one another thus increase the stiffness of the
structure.
