Design to reuse & insulate refugee camp tents

18/11/2018 at 14:08

Design method to reuse existing refugee camp tents and further insulate them from temperature / fire / missiles at low cost

Summary Design to reuse existing refugee tents, 1. inflate supporting bladder or frame .2. cover in insulating layer of plastic filled plastic bottles & cans, 3.then encase in fire resistant foam or foamed cement and 4.extra optional external fabric layer   5.Then cover in soil / sand / debris

This design is an idea by Paul Ridley alone on the 18-11-18 so far without prototyping, and has been passed to potentially interested parties for comments, and put in the public domain on the cabinz blog / Twitter / Facebook

The strength / USP of the idea (if possible) is that a foam or foam / cement layer can be made to adhere to the outside of an existing fabric tent. If not, such a fabric will have to be used in future , so the idea works.

The tents or shelters like at http://www.reciproboo.org/ can be delivered / installed quickly, then this idea built up  / improved as the empty bottles / cans/ cement / foam become availableMethod1. Inflate a supporting bladder inside tent with air or support with interior frame.

This will stop the foam / cement seeping through the fabricI presume this air tight bladder may have to made to fit the shape of each type of refugee tent. http://www.ConcreteCanvas.com use a similar bladder method in their shelters.2. Cover in an insulating layer of used waste polystyrene / plastic filled plastic bottles (eco-bricks) , cans or UbuntuBlox.

These will have varying levels of fire resistance, which will need to be considered in their use. This could reuse the packaging waste from the refugee camp / diaster area

Perhaps if the structure is strong enough the bottles could also be filled with local soil or water, built up in layers to take weight .  The choice of bottle infill would be dictated by the environment

Note: this infill may need to be with spacers allow foam /cement to succesfully form a load bearing matrix around the infill. Perhaps these could be made by cutting up plastic bottles or making plastic extrusions locally via the http://www.preciousplastic.com extrusion / 3d printing methods

.Cabinz have previously experimented with used bottles / cans taped together with fibreglass reinforced packaing tape to form modules . We have also experimented with inserting these into metal drywall frames to form supporting beams3.

Then encase in foamed  cement / concrete, so this forms an interlinked mesh structure around the bottles / cans

Although this may not be needed,  perhaps, while cement layer is wet another layer of cement permeable fabric can be laid  on top , so when dry it forms a stronger composite for harsher environments, with the 2 fabric layers.

Perhaps these 2 layers of fabric could be sewn together with a sewing awl for extra strength before the foam / cement sets.Note: P Ridley has proposed ideas to improve Refugee Shelters before, which were mostly ignored, yet possibly may have proved correct .

Hopefully this is not the case again here, and the feasibility / potential of this idea will be fully researched / funded & explored or discarded.

cheers , at £143 , perhaps a 1/8 / 2m inflatable Water walking ball could be used as the reusable internal inflatable ballder ot inflate the tent
