DIVISIBLE BELTS AND STRENGTHENING STRENGTHS OF NATURAL TRAJECTORY FOR SPHERICAL OR CLOSE TO SPHERICAL COMPOSITE SEALED PARTITIONS

摘要

1. A partition containing: a substantially spherical dome-shaped element (10) comprising a peripheral portion (20) and an upper point (16), with an axis perpendicular to the dome-shaped element (10) at the upper point (16); the first group (12) a strap extending from the peripheral portion (20) of the dome-shaped element (10) along geodesic lines defined by the first pair of actual poles outside the peripheral portion (20) of the dome-shaped element (10); and a second group (14) of straps extending from the peripheral portion (20) of the domed element (10) along second geodesic lines defined by the second pair of actual poles outside the peripheral portion (20) of the domed element (10), with a separate strap in the first group (12) ) the strap is blocked only once with one separate strap in the second group (14) of straps. 2. The partition according to claim 1, wherein the first pair of actual poles and the second pair of actual poles are orthogonal to the axis. 3. The partition according to claim 1, wherein the second pair of actual poles is perpendicular to the first pair of actual poles. 4. The partition according to claim 1, in which the dome-shaped element (10) is made shallow and is opposed to a conical angle of 45 ° or less of a spherical surface. The partition according to claim 1, in which the dome-shaped element (10) is made deep and is opposed to a conical angle of 45 ° to 85 ° of a spherical surface. The partition according to claim 1, in which any overlap is a simple overlapping of the straps. 7. The partition according to claim 1, in which, in any overlapping, the strands of the first strap are intertwined with the strands of the second strap. 8. The partition according to claim 1, in which all the strands of the straps end in the peripheral section (20) .9. The partition according to claim 1, in which the strands of the straps are completed gradually
