Filed: 2008-04-03
Abstract: This invention refers to a variety of mechanical joints-nodes used to interconnect between them straight parts tubes, rods, beams to construct trusses. In all cases of truss constructions the main question is how to interconnect the straight parts and the usual up to now practices have limited possibilities for mass production of standardized joints-nodes or straight sections that can secure uniform-fixed mechanical strength at the point of interconnection and flexibility in the architectural design. The present invention has achieved the design of a series-variety of standard components for the assembly of joints-nodes with variable-self adjusting angles with moving arms (3) (4) (5) (6) (7) and a series-variety of standard joints-nodes with fixed angles (8) (9) (10) (11) (12) (13) (14) (15) and with the form of DISC (49) or SPHERE, as well as of a two part mechanical connector consisting of a male (47) and a female (48) part, which can be interconnected with lateral movement and interlock with a small turn and can be fixed at the ends of straight parts (21) (25) and be embedded in the arms of the nodes (3) (4) (5) (6) (7), as well as the devising of a method of screwing and unscrewing straight parts (21) (25) by turning in one or the other direction with opposite threadings at their two ends (22R) (23L) and respectively at the arms (3L) (3R) (4L) (4R) (5L) (5R) (6L) (6R) (7L) (7R) of the nodes. All the above can be produced with standardized industrial methods, providing uniform-fixed mechanical strength at the points of inteconnection, flexibility in the architectural design and significant lowering of costs.
