A connecting linkage is provided between two structural members which includes a pinned connection to allow rotation of one structural member with respect to the other and which permits adjustment and alignment before locking the device in position without the need for drilling a precisely positioned hole for the pin in the structural member. An oversized hole is formed in one of the structural members and the pin is placed through the hole. A fist support plate having pin-sized holes is then placed over each end of the pin followed by a second pair of support plates are having pin-sized holes. The assembly is then moved with respect to the first structural member as permitted by the oversized hole around the pin into a desired position. The second pair of support plates are then welded to the second structural member and the first pair of support plates are welded to the first structural member. If desired, the pin may be welded to the second pair of support plates. The first pair of support plates and the first structural member are free to rotate about the pin and with respect to the second pair of support plates and the second structural member.

Organe d'assemblage placé entre deux pièces de charpente, comprenant une articulation à tourillon qui permet la rotation de l'une des pièces de charpente par rapport à l'autre et, par conséquent, l'ajustement et l'alignement avant le blocage du dispositif et qui évite de devoir percer un trou dans une position précise pour installer le tourillon. Le tourillon est inséré dans un trou surdimensionné percé dans une des pièces de charpente. Une première et une deuxième paires de plaques d'appui percées de trous de la grosseur de tourillon sont placées par-dessus les extrémités du tourillon. Grâce au trou surdimensionné entourant ce dernier, l'ensemble est ensuite déplacé par rapport à la première pièce de charpente et placé dans la position désirée. La deuxième paire de plaques d'appui est alors soudée à la deuxième pièce de charpente, et la première paire est soudée à la première pièce de charpente. Le tourillon peut facultativement être soudé à la deuxième paire de plaques d'appui. La première plaque d'appui et la première pièce de charpente peuvent pivoter autour du tourillon, par rapport à la deuxième paire de plaques et à la deuxième pièce de charpente.
