Abstract: 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, 1979In 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.
