Abstract: A system for constructing buildings utilizing a conical connector to fasten rods connecting structural members of a building. The conical connector is a rigid, solid device, circular in section, with an axial bore. The connector has a flat top surface and bottom surface perpendicular to the bore, a ring-shaped flange midway between the top surface and the bottom surface, and a sloping surface between the top surface and the flange and between the bottom surface and the flange wherein the circumference of the connector as defined by the sloping surface increases as the flange is approached, forming a cone. The sloped surface of the connector engages a recess in a structural member of the building. A tensioning mechanism passing through the bore in the connector applies a coupling force to hold the connector against the structural member. A multiple cone connector for joining adjacent modules of a building may be formed by joining the flanges of at least two connectors to form a single continuous flange.
