As a graduation project at the Delft University of Technology (The Netherlands) a shelter for use in disaster help is developed. The project is done in close cooperation with the Dutch Doctors without Borders (‘Artsen zonder Grenzen’). Finishing date: May 2007
The shelter is based on a high pressure (75 PSI) inflatable construction. It can be fully assembled and compactly packed at the manufacturer and therefore the only thing to do on site is inflating it with help of the built-in, human-powered air-pump. Simply by pulling a chord an inflator is activated and after 13 minutes the shelter is ready for use. Since no further instruction or external electrical energy is needed everybody is able to put up the product everywhere in the world. No parts can get lost during transport.
To make larger structures it is possible to connect the shelters to four sides. Walls can be fully removed.
The shelter cover consists of two separate layers, which provides basic thermal insulation in winter situations and cooling, ‘natural ventilation’ in hot climates. If needed, extra thermal insulation can be applied. The construction is designed to be able to carry a snow load of 70 kg/m2. In windy areas the shelter can be guyed to the ground.
The product is interesting for use in a later stadium of emergency aid: the full roof can be separated from the lower part and put on a wall or other stable structure, which is easily built with locally available materials. This saves time, building expertise and expensive roof construction materials while making it possible to make a nicer living area with for example real doors or windows.
After use, the product can be deflated, packed and transported compactly.
The product can be fully disassembled and materials used are chosen to be fully recyclable.
