Igloo-type building for use in developing countries and disaster areas

摘要

The building is constructed partly by using flat plates (6) of cellular plastic arranged in concentric rings and held together by tongued joints (7), and partly by wedge-shaped pieces (8) connected to a vertical door frame (9). A rubber sheet (10) is drawn over the whole structure. The joints are reinforced by an internal skeleton of aluminium tubes (11), to which are welded plate angles (12) which engage in the joints. The skeleton also supports inwardly directed plate angles (13) for engagement with an inner wall (14) formed by plates. A sill rail (15) comprises partly a track for receiving the lowermost ring of plates (6) and angles (17) for anchoring a floor made of cellular plastic with a wear surface (19) of hardened masonite (R.T.M.). Three such buildings are joined to form a unit by having their door frames being connected to one another, and together with an outer door form a quadratic wind break provided with a roof.
