Abstract: Folding modular structure for a tent or similar for fast mounting includes an assembly of tubular profile bars permitting in particular to form at least two arches facing each other connected by at least two purlins one of which is a ridge. The ridge purlin is formed of the butting of two profile bars, made integral, each by their other end, with a ridge member. That other end includes, on the one hand, a pivoting device for pivoting, in a limited way through an indexing mechanism, on the ridge member according to an axis perpendicular to the plane of the arch. The pivoting device allows the folding back of the shape parallel to the arch, the butting of the two profile bars occurring through encasing means capable of ensuring their immobilization in axial pivoting according to angular positions defined by the indexing mechanism.
