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.



LBL member

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

Wall Cladding

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.

Wood studs

Push Props

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.


Z shape Purlins Members

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.




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.
