<p>improvements to tensioning systems for flexible roofs, which consists of a protective material, preferably with features such as water repellent and elasticity such as canvas, rubber, greenhouse oilcloth, or any other features that are similar, the configuration should preferably be rectangular or square, it is the surface where the rows of ribs (3 and 4) with distance between and using mechanical means are fixed to the membrane in question. Optionally the sides of these roofs can be joined successively to other similar roofs to form a larger roof (figures 31, 32, and 83). These roofs are expected to have an arc between the roof connections. The natural function of tension systems are as follows: to remain in rigid or tense state thanks to the vertebral ribs (figure 5) and exterior ribs (figure 11) caused by the tension of rope or cables, (figure 11) roofs may vary in geometry between more distant posts, which goes from the straight (figure 33) to the inverted curve or arc (figure 31).</p> |
