Abstract

A space framework for building up dismountable ceilings and walls which comprises pyramid-shaped elements each including reinforced concrete slabs with corners connected to steel profiles which are adapted to be subjected to tensile and pressure forces and come together at a joint. The pyramid-shaped elements are at the corners of the pertaining reinforced concrete slabs put together by means of connecting elements to form a space confining surface adapted in its plane to take up pressure forces. The joints at the tips of the respective pyramids are connected to tension members extending substantially parallel to the reinforced concrete slabs.
