Tank with internal tension beams

Abstract

The present application concerns a substantially prismatic tank having internal tension beams having a cross section with a web and orthogonal flanges along the edges of the web, the beams being arranged in alternate orthogonal layers and being connected to each other at at least some crossing points, wherein the beams are arranged with their flanges oriented vertically and their webs oriented horizontally.

1 . A substantially prismatic tank having internal tension beams having a H- or I-shaped cross section with a web and orthogonal flanges along the edges of the web, the beams being arranged in an assembly of horizontal, orthogonally crossing tension beams, the beams being interconnected at the crossing points, wherein said beams are arranged with their flanges oriented vertically and their webs oriented horizontally, said beams being interconnected at the at least some crossing points by spacer elements the spacer elements being attached to the web or at least one of the flanges of the beams.
