Abstract: Roof for a storage reservoir, such as a silo, having a frame with a rigid peripheral element, a central core element and a plurality of tension elements which are distributed about the peripheral element. The central core element includes at least two supports that are mutually connected at an axial distance apart. The tension elements are stretched between each support on the central core element and the peripheral element. The tension element is fixed to the central core element and the tension element such that the tension of the frame is varied by varying the distance of the tension element is stretched between the rigid peripheral element and the central core element.

Abstract: The invention is a reservoir for placing in a fixed position on the ground, for example a swimming pool or a storage tank for liquid and/or solid (bulk) goods having little or no cohesion, for example crop products, coal, manure, spreading salt and the like, having at least a bottom and an upright wall connecting thereto which is resistant to outwardly directed pressure. The invention further provides to this end a reservoir of the type referred to above which displays the feature that the upright wall consists of a number of vertical piles placed in a closed configuration at intervals from one another, a vertical wire mesh arranged between these piles and a bottom element extending on the bottom, on which element an upright wall part is formed or arranged resting against the inner side of the said wire mesh.
