Carnation Walling - Internal Wall Bracing Etc

Star Internal walls are handled a bit differently as there is no EPS to glue.

Internal Concrete Walls

Can straight away fit vertical batons on both sides of the wall.

Fit them every 6 feet at primary locations.  This is enough to support the ceiling beams but is still wide enough apart to allow the plywood to be fitted later.

Starting Vertical Batons Internal Wall 

Use 1/2" conduit spacers that are 9.5" long.  (The conduit pieces will get cut to 8" later when fitting the plywood.)

Internal Columns

Sometimes in the structural house design it is necessary to provide more support than a short length of regular wall can provide.  I use 2 foot x 1 foot rectangular columns in two places in the basement.  These are formed using sawmill sawn lumber.  At the base it uses a short length of key notch in the slab.

Slab For East Column 

To make the rectangles of wood, use a jig as shown below.

Basement Column Jig 

The lumber used is 5" wide (for consistency).

Basement Column Rectangle Screwed 

Pile up the rectangles to the required height to form a column.  Note you will need to later do some disassembly of the rectangles to fit the rebar.

Temporary Mezzanines

It is useful in some places, eg the porticos, to implement a mezzanine floor.  This can provide some rain shelter but it is also useful to hold the walls the right distance apart.

Vertical Baton At Secondary Position For Floor 

Put wood planks between the horizontal bracing.  The length of the planks needs to be accurate and exactly as per your CAD drawings.

Over the planked area add some 6mil polyethylene and then some orthogonal wood planks on to to hold it down.

Internal divider walls

As shown on your CAD floor plan there are likely to be various internal wood walls that divide up the space.  In the finished house they are not structural walls but they are useful to help support the big ceiling beams so they don't sag under the weight of the wet concrete.

On your floor plan there may also be some mezzanine floors for storage or whatever.  Implementing them now is useful because it holds the walls the right distance apart and generally makes the overall structure more rigid to stop it moving about when you pour concrete.  Once you have added the flooring/ceiling above you can use the mezzanine for storing building materials and tools.

Given the important role that internal wood walls forefill, there is more information on their implementation in the section on ceiling beams.

The story so far

At this stage you should have the entire house outline (the outer edge of what will be wall concrete) done in exactly vertical 2x4 batons spaced 2foot apart (with variations at the center of wall sections) with angled bracing about every 6 feet.  The internal vertical 2x4 batons are all exactly the same height and they have threaded rod at many strategic locations ready to accept the EPS.
