Upgrading the emergency RSK

Steel frame shelter

Bamboo frame shelter

Options to improve the basic steel emergency shelter include:

1. Converting it to the double frame shelter.

2. Build solid walls as in the earthbag shelter.

3. Insulating the roof.

In addition it should be noted that the steel shelter is designed to be easily repaired and worked on without special skills or materials.

The following points illustrate this "workability " :

Benefits 21

All the joints are simply cross lashed with sisal twine. They can easily be strengthened and worked on while being inside the shelter.

Steel poles are interchangeable. If any part of the shelter fails it can easily be repaired by simply moving a pole from a less vital part of the frame. 

Here 2 poles have been removed from the central frame to demonstrate that the shelter can still be used..

Benefits 22

The hooks for rope attachment can easily be made by hand from the standard 5mm steel pegs.

If hooks are not available the ropes can be fixed to the ground as in the bamboo RSK.

In this prototype shelter test it was shown that covering the roof with available foliage insulation can lower the inside temperature by over 10 degrees centigrade.

The frame can be worked with other locally available materials.

Here a smaller gauge (19mm) steel prototype frame is being used with corrugated iron sheets.

Corrugated sheets can be attached by wire to the frame to make a rigid roof.
