ABSTRACT:
The ends of cylindrical girders are provided with spherical members mounted thereto. Sets of twelve, eight or four girders can be connected by a single joint, depending upon the configuration thereof. Each joint includes first and second parts which assemble, by means of a single bolt, to form a structure within which the spherical girder end members are received. The joint parts are provided with openings through which the girders extend. Some of the openings are elongated so that the position of the girders extending therethrough can be varied relative to the joint. The joint parts may be provided with external structural rigidity enhancement members.
