<p>This patent describes a new self-sustaining modularized device for the construction of covering structures for large vains, replacing traditional structures made by metal components or concrete, the new structures being more reliable and cheaper than traditional techniques, speeding up the work needed to assembly the structure. The invention is a new self-sustaining modularized device (1), especially developed for the construction of covering structures for large vains, the device being made in one piece by the injection of a thermoplastic material on a mould, this device having the shape of a vertical empty prism with thin walls, with its base (2) forming an equilateral triangle, this device does not have the upper triangular side, the lateral sides (3 and 4) being vertically positioned, while the wall of third side (5) is inclined by an angle between 75° and 90° from the horizontal triangular base (2), the edge (6) between the two vertical sides (3 and 4) also having the same angle from horizontal plane, each lateral side (3, 4 and 5) presenting two circular holes (7) for two bolts or other kind of junction components, and a third hole (8), larger, in order to allow the flow of heated air crossing the whole structure.</p> |
