Abstract

Soutènement La grille comporte des fers en long dont chacun porte à l'une de ses extrémités un mécanisme de blocage, pourvu d'organes d'arrêt, qui agit sur l'extrémité en regard d'une grille adjacente pour la bloquer, ladite grille étant formée de fers transversaux passant au-dessus des fers en long auxquels ils sont réunis par soudage aux points d'intersection. On prévoit pour chaque mécanisme de blocage, un organe de serrage guidé sur un fer en long particulier entre deux fers transversaux successifs, l'organe d'arrêt servant à bloquer ces organes de serrage sur leurs fers en long, tandis que les fers en long de la grille contiguë peuvent être fixés amoviblement, par solidarisation mécanique, auxdits organes de serrage. Application : exploitations de mines et travaux souterrains.Support The grid comprises lengthwise bars, each of which carries at one of its ends a locking mechanism, provided with stopping members, which acts on the opposite end of an adjacent grid to block it, said grid being formed of transverse bars passing above the longitudinal bars to which they are joined by welding at the points of intersection. There is provided for each locking mechanism, a clamping member guided on a particular long iron between two successive transverse bars, the stop member serving to block these clamping members on their lengthwise irons, while the lengthwise irons of the contiguous grid can be removably fixed, by mechanical attachment, to said clamping members. Application: mining and underground work.
