PURPOSE: To enhance the freedom in designing latticework structure by branching off the rod fixed in coupling hubs either orthogonally or suitably inclined by means of connecting grippers by a knot formed by two junction plates. CONSTITUTION: A latticework structure rod 1 is disconnectably fixed on each junction plate 2 at right angle with the plate via a coupling hub 4. The surrounding flanges 5 are inclined at 45 degrees and connectable with each other. A semi-circular bead 6 is respectively formed on the distal end thereof. The latticework structure rods 1 are inclined via connecting grippers 22 and disconnectably clamped there. In this way, the rods 1 fixed in coupling hubs 4 can be branched off either orthogonally or suitably inclined by means of connecting grippers 22 fixed on an enlarged attachment 12 by a knot formed by the two junction plates 2. Thus, it is possible to enhance the freedom in designing, the fixing strength and the assembling convenience of the latticework structure. |
