<p>The connector elements are shaped from sheet metal and screwed independently connected bar attachments. These connect the nodal points in three-dimensional lattice structures made from open cross-sectioned bars. End plates with a hole in each are welded to bar ends, at right angles to the bar axis. The elements have flat attachment faces, with an internally threaded hole or a sleeve nut inserted in the hole at right angles to the bar axis. Bars are screwed to nodal elements with rigid high tensile screws.</p> |
