Abstract

The core is made up of four side-planks (1,2,3,4) corresponding to the four sides of the housing unit being moulded. Four identical angled-planks (5) join the sides into a quadrilateral. All the planks are joined to a centre beam (6) by means of several links (7,8) of different lengths. The centre beam (6) can be raised by means of a ring (9) on its inside reinforcement (10). The side planks have a cross-section in the form of an isosceles trapezium, with narrow base facing outwards. The side-planks (1,2,3,4) fit together flush between the angle-pieces (5). The core is placed on a prefabricated foundation-slab (11) forming the floor of the housing-unit.
