Major Assignment - Poster

Major Assignment - Physical Model Complete!

Here are photos of the completed model:

I cut away at the first floor wall on one side to continue with the cut made by the bearer to show the reo connection.

-------------------------------------------------------

I built scaffolding to hold up the first floor to show illustrate the construction process for in-situ suspended floor slabs. Another way would have been to use a 'bondek' material to support the floor but I feel that Ando would have used removable form work rather than a permanent solution.

-------------------------------------------------------

The grey material is supposed to represent asphalt. The box gutter should have a 1:200 slope. The roof should also have a slight slope of 2-3 degrees so that the water doesn't puddle but flows to the gutter.

-------------------------------------------------------

I had a bit of fun making bar stools for the reo to sit on. These can be made of plastic as well as steel. I was thinking about it after, and I'm not sure if there would be two layers of reo in a 200mm slab like this. I think it would be up to the structural engineer to choose either one layer of heavier reo or two layers of lighter reo. It probably also comes down to cost also.

-------------------------------------------------------

How the bearer connects to the column. Ligatures would be more closer together at connections like these.

Major Assignment - Physical Model Update 2

Update from work on model today, worked for 8 hours and still haven't finished... Will get the rest done tomorrow.

--------------------------------------------------------

--------------------------------------------------------

Ground Slab: Here I have shown the ground slab with all the components used. The form work, gravel, membrane, mesh and concrete.

--------------------------------------------------------

Formwork: I needed to shorten the bracing on the outside because it would hand out further than the base. I have also left out the piece of the form ties that sits on the outside of the walers. I think it would be too much to show this in the model. I will show a detail of how it will properly look in the poster.

--------------------------------------------------------

Detail of the re-enforcement: It took me quite a while to get all the wire to sit together straight and even. I had to tie the bent horizontal reo to the vertical reo because it wasn't going to sit on its own and my glue didn't hold.

Major Assignment - Physical Model Update

Here is where I am so far:




Still going... I need to build up the formwork wall and the first floor slab and roof.

Major Assignment - Physical Model Update

Yesterday I bought what materials I thought I needed to start the model today. So far I haven't made much progress in a 3D sense, but I have cut up a lot of foam core to make the columns and bearers. I have decided to cut off the edges at 45 degrees so the there is a seamless connection between the faces of foam core. Haven' t got any photos up because I left my camera at home but hope to put some on soon.
I still haven't got any wire for re-enforcing but will have to get some asap. I'm not really sure if I will be able to get this model as well as the poster done by Friday. I might email my lecturer about it tomorrow.


Form-work:

Form-work is just as important If not more important than the concrete in in-situ construction. I have looked at a few books from the library but the most useful and most detailed has been the book I got info on the re-enforcement I put up earlier. The book is: E Allen, J Iano, ‘Fundamentals of Building Construction, Materials and Methods’, Fourth Edition, John Wiley and Sons Inc., New Jersey 2004.


Some form-work drawings I have traced:
