PCT No. PCT/DE78/00028 Sec. 371 Date June 26, 1979 Sec. 102(e) Date June 25, 1979 PCT Filed Oct. 24, 1978 PCT Pub. No. WO79/00237 PCT Pub. Date May 3, 1979 In a tent structure with support arches and with a roof skin the support arches are constituted by a plurality of rigid arch elements which are tensioned together by means of a bracing wire attacking the feet of the relevant support arch. In order to permit an elastic deformation of the support arches under the influence of wind or snow loads and to enable the pretensioned support arches to be erected by pivoting about the chord of the arc, the arch elements (1) are joined together articulately at their butt ends, while the axes of articulation defined by the configuration of the butt ends extend perpendicularly to the arch plane. When a plurality of bracing wires (7), which are spaced apart approximately perpendicularly to the arch plane, extend in the arch elements or are passed along the latter, the rigidity against bending out of the arch plane can be adjusted separately on each side. The invention is applicable predominately to large tent structures, e.g., festival or sports halls or storage sheds.
