ABSTRACT:
A skeletal framework structure employs a special junction for securing together the ends of the framework members, the ends of one pair of which members have longitudinal axes lying in a common plane while the axes of others of the members extend at angles to that plane. The framework members having axes lying in the same plane may be parts of straight tubular arch members in the framework, while the framework members extending at an angle to that plane may constitute spacer members, or purlins, extending perpendicular to the plane of the arch members, or may constitute diagonal bracing members extending at other angles to the plane of the arch members. In the junction, a first flat plate member extends parallel to the plane of the axes of the arch members and bears against and bridges the adjacent ends of said arch members, while a second similar plate member parallel to the first plate member bears against the opposite sides of the same arch members. Two angle members are preferably also employed, one on each of the opposite outer sides of the two plate members, and each having a first flange portion which extends over and against its associated plate member. The angle members, the plate members and the arch members are bolted and clamped together by four bolt-and-nut combinations, two through each of the arch members. The second flange portions of the two angle members are bolted to the ends of the purlins, and the ends of the diagonal brace members may be secured directly to the plate members by two of the four bolts. The two plate members and the two angle members are preferably substantially identical to each other, and may be used interchangeably in other junctions in the framework assembly. The arch members and purlins are hollow tubes of uniform, preferably rectangular, cross-section.
