The joint (1) has a core projecting from an upper plate and integrated with the plate, where the core is in the form of solid cylinder. A gusset piece has peripheral edge parts that are integrated with the core and the plate, respectively. A fixation unit i.e. bolt (4), is formed of a screw (4a) and a nut (4b) to fix flattened diagonal braces (3) with the gusset piece, where each diagonal brace is extended between the joint and another panel joint of upper and lower sheets of a three-dimensional framing structure. The fixation unit fixes flattened chords (2) of a same sheet with the plate. Independent claims are also included for the following: (1) a three-dimensional upper and lower sheet framing structure comprising bars (2) a method for fabricating the three-dimensional upper and lower sheet framing structure (3) a press for fabricating the three-dimensional upper and lower sheet framing structure, comprising a mobile plate. |
