Method for Producing Triangular Elements Designed for the Manufacture of Structures and Resulting Triangular Elements

摘要

The invention concerns a method for producing structures, whereof the geometric shape can be broken down into triangles, and which provide without any further treatment the structure with integrated airtightness, the double airtight partition enabling a coolant to be circulated or a relative depression to be generated and hence a more efficient thermal insulation, and also facilitating mounting with above all no need for a particular work site or complex and expensive foundations even on broken terrain. The method consists in prefabricating by moulding followed by assembling single-unit triangular structures, whereof the inside of lateral parts (5) is hollow through use of profiled sections, whereof the tops (6) contain no joints as a result of a plastic coating. The tops (6) comprise defined arc-shaped indentations (7), whereof the outer surfaces on either side comprise grooves (8), whereof the inner surfaces include a shoulder (9) comprising a groove (10) on both its surfaces, whereof the sides can have an extra thickness (11) at a specific angle, which has on one of the sides at least three openings (12) corresponding to recesses provided in the profiled section. Said structures are prefabricated in series by coating with plastic material, in a mould, a metal profiled section. The method is particularly designed for producing domes, greenhouses and submarine bells.
