Construction system consisting of construction elements made out of either expandible or rigid material, with at least one jointing eye, into which a pinch/jointing element is inserted. The jointing element has a) an eye at each end; after being inserted in the construction element it is expanded either by introducing air, gas, fluid or other expansion material, or b) either i) eyes which are screwed on, or ii) pivot, screw, pinch, hinge or slide joints which enable a solid ''pressure'' joint to be obtained between the construction elements. |
