An automated weldless inter-locking grating assembly for bridge decks and the like which includes a plurality of primary load-bearing members located laterally, a plurality of transverse secondary load-bearing members and a plurality of trimorphic load-bearing members. Secondary load-bearing structural members are inserted sideways into apertures of primary load-bearing members and trimorphic load-bearing members. Thus, when a horizontal force is applied to alternate primary or trimorphic load-bearing members or any combination thereof, rotation of secondary load-bearing member or members occur to efficiently and automatically lock secondary load-bearing member or members into primary and trimorphic load-bearing member or members completing assemblage thereof into a rigid structural form.
La présente invention porte sur un ensemble en treillis à emboîtement automatique sans soudure pour tabliers de pont et structures semblables qui comprend plusieurs éléments porteurs principaux latéraux, plusieurs éléments porteurs secondaires transversaux et plusieurs éléments porteurs trimorphes. Les éléments structuraux porteurs secondaires sont insérés de côté dans des ouvertures des éléments porteurs principaux et des éléments porteurs trimorphes. Ainsi, lorsqu'un effort horizontal est exercé alternativement sur les éléments porteurs principaux ou trimorphes ou toute combinaison d'éléments, il se produit une rotation d'un élément ou d'éléments porteurs secondaires afin de bloquer efficacement et automatiquement l'élément ou les éléments porteurs secondaires dans l'élément ou les éléments porteurs principaux et trimorphes, ce qui transforme l'ensemble de ces éléments en une forme structurale rigide.
