Abstract: In a tent roof having arched support elements (2, 3), over which a diaphragm (1) is stretched, at least three intersecting arched support elements (2, 3) are provided, whereby at least two support element ends (4) at a time are able to be fixed adjacent to one another on the foundation in an arch terminus area (12), at least three arch terminus areas (12) are provided, and traction elements (7) running approximately in an arched shape, which engage on the diaphragm (1), in particular on the diaphragm edge, are stretched toward the arch terminus areas (12).

Abstract: An in particular frustoconical hollow body (1) which can be stabilised by positive air pressure and which can be anchored to a base support (30) by way of bracing means is composed of a plurality of flexible material webs (4 to 12) which each extend in the peripheral direction of the hollow body (1). The mass in relation to surface area of the material webs (4 to 12) varies over the length of the hollow body (1).
