The Reciproboo shelter in winter. Reducing the risk of hypothermia in a cold climate

The Reciproboo shelter has some unique properties to help a family survive a severe winter

1. THE ROOF CAN SUPPORT HEAVY INSULATION.
Not only does this make the shelter warmer but the exceptional strength
of the reciprocal frame roof means it will not collapse under heavy snow.

2. THE WALLS CAN BE BUILT UP FOR ADDITIONAL INSULATION AND SECURITY.
Unlike traditional structures the reciprocal frame roof only requires support at each corner;
this allows walls to be built up using available materials such as earth bags and masonry etc.

3. A SIMPLE RECIPROCAL FRAME CAN LIFT CHILDREN AND THE ELDERLY OFF THE GROUND.
This lowers the risk of hypothermia by reducing heat loss to the ground and is particularly useful
when there is surface flooding.

4. A SIMPLE RECIPROCAL FRAME CAN BE USED TO MAKE A SLEEPING CASPULE.
This frame creates a warmer micro-climate for sleeping 4 adults.

The Reciproboo will not collapse under the load of heavy snow

The steel frame Reciproboo shelter is used for the following examples. However, all these options also apply to the bamboo frame shelter.

In a cold climate the shelter is completed with a second tarpaulin. If a second reciprocal frame is inclined against the first frame then the whole roof will support insulation.It is this shelter that we are proposing for Syria.

Even this basic 7 pole single frame Reciproboo can be lifted onto any support posts or, as in this case, a wall.
This reciprocal frame roof is at its strongest when near horizontal and is able to support heavy insulation in winter. Support is at the centre where it is needed most.

Many relief tents are totally unsuitable for a cold climate. The sides of these "A" frame tents cannot be lifted or support insulation.
Most refugees in cold climates do not receive a winterised tent; instead they receive tarpaulins and some basic tools to build a shelter.

THE INSULATED COLD CLIMATE STEEL FRAME RECIPROBOO SHELTER:

A larger capsule is made simply by adding 2 sections to the upper arms of the frame as in this photo.

The sleeping capsule is based on the storm shelter.

Inside the sleeping capsule is a comfortable space that is easily ventilated.

2. Option to elevate sleeping area off the ground:

Sleeping on the ground results in a serious loss of body heat by conduction.
Children and the eldery are particularly vulnerable to this heat loss and the following example is specifically for the purpose of getting a simple elevated platform for children to sleep on. It relies on the exceptional strength of the reciprocal frame.

Heavy rain can make shelter sites vulnerable to flooding. This frame offers the potential for keeping shelter occupants and their possessions dry, thereby reducing the risk of hypothermia.

Option to use the steel reciprocal

frame roof for a stove flue.

In this example the existing central square aperture (outlined green) is being used to take the stove flue.

Unlike a tent this shelter already has a steel frame to take the required fireproof flue panel. Other steel frame apertures in the roof can be made use of to position the stove where required ( eg next to a wall).

The versatility of this shelter makes it possible, in an emergency situation, to build an open fire and vent it through the roof. This is similar to the TeePee that uses the same reciprocal frame construction concept.

By removing some of the steel sections from the roof frame it is also possible ( in an emergency situation where lives are at high risk from severe cold ) to build a modified shelter on the windward side of an open fire.

There is no additional cost for this ( it may actually save on the cost of existing flues by being easier to install ).
