Detachable, exact joint between thin pieces, to transmit compressive, tensile, shear and torsional stress

摘要

Here, a connection is described between two pieces, where conical depressions C have been formed in surfaces to be joined on pieces to be joined. Tapered spacers D which tap off from the center toward their ends have been placed in the recesses, and the spacers are tightened, for example, by the action of clamping means E, for example screws. The screws go through the pieces to be joined as well as the intermediate pieces and are tightened for example with the help of nuts. The surfaces of the connecting sides of the pieces to be joined do not contact each other, and the short ends of the intermediate pieces do not contact the bottom of the recesses. Pressure, shear and torsional stress are transmitted via the conical surfaces of the intermediate pieces and the walls of the recesses. Tensile stress is transmitted via the clamping means and the surfaces which face the recesses in the pieces to be joined.
