• the purpose of the invention is to solve the problem of achieving a completely flexible and dismountable building, including components which after repeated mounting operations still possess such a strength and durability of shape that they function and can be reused.
• the outer and inner design of a building is often determined by local taste and tradition. Within the same region also the personal want and taste vary considerably. Thus, it is important that all different tastes and traditions can be satisfied. This has also been considered when designing the system according to the invention.
• the advantages mentioned are achieved because the primary beams are load supporting units and stepless fastening means for secondary beams, exterior elements and insulating blocks.
