MAJOR PROJECT POSTERS

DETAIL 1: RIDGEBEAM CONNECTION
DETAIL 2: CONCRETE PANEL CONNECTION
DETAIL 3: CONCRETE PANEL CONNECTED TO SUSPENDED CONCRETE FLOOR

MAJOR DETAIL: END WALL CONNECTION

Site 4: Deakin University Extension Geelong

The stanchion is coated with a special white fire resistant enamel/paint.

The beam and the end plates are fixed with many circular bolts. The beam on the left has a large steel plate . In this case, the original beam did not meet/reach the ceiling, so an extra beam had to be incorporated. To make this connection stable and rigid, many bolts and a large metal plate was used. Welding of the bolts was also incorporated to further increase the stability.

This image shows temporary props fixed to a concrete column.

I thought this was an interesting image, as it appears that a pad footing is embedded into the walling/brickwork.

Roof bracing is definitely needed for this building, due to the large roof surface area. Circular beams are used for the bracing. Which would work more effectively: circular or square sectional beams?

Site 3: Geringhap Street Geelong

Construction Type: Pre-Cast Concrete Panels with suspended Concrete Floors



- Square concrete columns
- Suspended concrete floors
- Temporary rails for safety
- Steel formwork for suspended concrete flooring
















-Pre-cast concrete panels





-Window frame.
- Protruding steel under panels to stabilise, hold them in place, and easily position them.
- May be used to lift the panels( Connects to machinery)?
















-Square column with exposed steel reinforcement, too connect the roof materials, ceiling or next suspended concrete floor to the column.

- Here are some photo's of Pre-cast concrete panels chained to a truck.

- The fixed in metal plates along with the furruls can be seen.

- These fixings allow machinery to lift the panels and they act as a connection between panels.

Site 2: Doherty's Road Laverton

Construction Type: Continuous Portal Frame


This building has internal stanchions supporting the structure due to its large span.








I think its interesting how the stanchion is not embedded into the the concrete slab. Could this be because the height of the stanchion is so tall, further fixings such as bolts and welding need to be done before concrete is filled into the space in order to increase its overall stability?



Bracing is included in the roofing in order to increase the stability and resistance to windloads or uplifts. More triangulation in the bracing of the roof is required due to it's large roof area (larger the roof area = more contact with the wind).




Here, i noticed that 1/3 of the walls are concrete panels. This is a more economical solution because having all the walls as concrete panels would be very expensive.




Here we can see how the temporary props are fixed to the concrete panels.
The circular holes in the panels are furruls, which are designed to lock all the metal plates to the beam.

Site 1: Doherty's Road Laverton

Construction Type: Tilt-Up Panel


- Boxing for Tilt-Up Panels are
arranged. (Corner/Angle Bars).
- Steel Reinforcement for Panels.


- Triangular Steel supports stabilising the wooden boxing.
- Steel Reinforcement positioned and ready for Concrete Pour.


- More Steel Reinforcement.

- Blue connections act as a connection that allows the panel to be lifted (furruls).



- Sheet mesh, bar-chairs, and corner/angle bars.
- The gaps in the concrete are designed to firmly place the tilt-up panels.


- Finished tilt-up panels during the concrete curing process.











After 3 weeks, the concrete panels have been erected and stabilised with temporary props.
When observing the connections and the overall form, I noticed that not all the concrete panels were cast on site. The major/large panels were pre-cast, and the shorter/smaller panels were used above openings. In the left image, i think the horizontal panels were cast on site. I noticed with them panels a few chips or damages caused maybe by the tilt-up process.













Both images show a few defects in both the floor slab and the top of the horizontal panel. The horizontal panel has two quite noticeable defects, that may have been caused by the machinery or chains used to elevate the panel.










The left image shows how the concrete panel fits into the gaps dividing the floor slab. Here, the panels are embedded into the gap of the slab rather than on top of it. This way, the panel is more fixed and less fixing, such as welding or bolts are needed to stabilise the panel.

The right image shows the continuation of temporary props or bracing.

The top image shows the connects of the temporary props.

The middle image shows a pre-cast panel. From what I've noticed, the panels with openings such as this one are pre-cast. Pre-cast panels achieve more accurate results. If this panel was to be constructed on a site, it will be very difficult to cut without causing any defects and to achieve an accurate result.

The bottom image shows a pre-cast panel that has not been elevated yet. The panel is very accurate and neat, with sharp corners and no evident defects.

These images show the metal plates that are cast into the pre-cast panel and used to connect one panel to the next. The cast- in metal plates are used to connect the panels using metal plates, as shown in the right image. They allow bolts to be fixed without causing any cracking or defects to the concrete panel.
In the left image, which shows the fixed metal plate, a small hole is positioned in the centre. This is where the bolts are fixed to.

Here, the top image shows sheet mesh between the slab and the panels. This shows that te panels are stiffened by the concrete that will be poured in this long narrow gap.

The bottom image is of a furrul fixed to a pre-cast panel. The furrul allows machinery to transport panels as it acts as a connection.
