All this was mounted on pallets to distribute the loads and not apply them concentrated on a single point. These last simulated dead loads in sand and crushed lumps with weights of approximately 50 Kg, previously weighed, were located on the upper outer perimeter of the platform simulating the construction system of the house. On several occasions the loads to which the platform was subjected to move the center of mass and cause balancing without any sign of deterioration were changed.

Abstract

La présente invention concerne une plateforme flottante composée d'un système de flottation, d'un système de sustentation, d'un système d'ancrage et de systèmes accessoires. Ces systèmes forment une unité qui s'élève verticalement en réponse à des changements du niveau de l'eau environnant. Le système de flottation restreint ses mouvements horizontaux au moyen du système d'ancrage, qui forme, à son tour, l'appui subséquent à terre au moyen du système de sustentation.
