FIELD: aeronautical engineering. SUBSTANCE: device has plates embedded in foundation. Mounted on these plates are vertical columns with longitudinal beams secured on them. Beams form framework for securing knife-edge joints, split plates and frames with joint units holding retainers and clamps. Plates embedded in foundation, vertical columns. longitudinal beams, split plates and frames with joint units are provided with sleeves at connected points. Secured in these sleeves are reference mark platform provides with attachment members. They form datum parting plane engageable with mating plane on member to be connected. EFFECT: facilitated procedure of assembly.
