摘要： A process for the assembly of at least one adjacent pair of component structural elements to form an upright vault structure, each of the elements having a recess, wherein the elements are arranged flat on the ground in the desired relative configuration and are temporarily joined together into an assembled unit by an assembly device, whereafter the device and the assembled unit are lifted and placed in a final position of the structure, and the joining device is removed from the elements. The joining device includes a post and a pair of opposed spaced jaw members mounted on the post for relative movement toward and away from one another, a pair of wing members being afixed to one of the jaw members, the wing members extending from opposite sides of this jaw member and toward the other of the jaw members and respectively engaging the recess of the structural elements. The jaw members are clamped together about the joined structural element.
