The roof frame of the RSK shelter is first lashed together on the ground. There is no splitting of bamboo necessary.
If the emergency shelter is being built then this frame is simply lashed to two bamboo props for support.
If the elevated RSK shelters are being built this roof frame is supported on 4 corner posts that have had simple slots cut in their tops using a saw or machete.
Building the roof frame on the ground means that all the family can participate in assembly. These cross lashed joints are not dependent on the quality of the lashing or strength of the tying; they can always be strengthened if needed by adding to or replacing a weak lashing after the frame has been assembled.
The Red Cross instruct villagers in RSK assembly.
