Abstract: A construction element is provided. The construction element comprises a base panel and two substantially perpendicular sidewall panels which together define a U-shaped channel having an internal cavity. At least one of the panels includes at least one panel opening dimensioned to allow the passage of a reinforcement or stabilising material into the internal cavity. The construction element further comprises at least one support plate (70) having first and second ends fixed to respective sidewall panels and extending substantially perpendicular to the sidewall panels across the channel so as to provide support to the sidewall panels.

Abstract: A modular construction system in which a number of three dimensional construction elements are adjoined to form a modular wall, ceiling or floor assembly. In their pre-assembly condition, each three dimensional construction element is formed from a planar metallic sheet (10) sub-divided by fold lines (12a, 12b) into panels (14, 16, 18) defining a multi-panelled sheet. Each panel lies in a common plane and at least one of the panels is deformable along its fold lines out of said common plane to form an assembled three-dimensional construction element for adjoining to other three-dimensional construction elements. At least one panel is provided with an opening (14a, 16a) dimensioned to allow the passage of a reinforcement or stabilizing material through the assembled three-dimensional construction element.
