Abstract (en)
[origin: EP0222456A2] The invention relates to a box-like structure, for example a roof structure, having a number of vertical, substantially right-angled walls comprising a number of elongate louvred slats running parallel to one another, and a cover plate supported by these walls. The invention has for its object to give a box-like structure, for example a roof structure, a form such that a great flexibility in dimensioning is achieved and that the box-like structure can be assembled simply on site with the use of a minimal quantity of very simple tools. In this respect the invention generally proposes a box-like structure of the type described characterized in that each of both end zones of each louvred slat is fixed between two spacers, these spacers being arranged in two rows extending transversely of the longitudinal direction of the louvred slats and being pressed towards one another by pressure means.
