A b s t r a c t A method for providing a tubular node in frame work struss structures, such as offshore platforms for oil drilling and production activities of the type consisting of interconnected legs and braces of steel tube elements. For formation of the transition between leg and brace in the node is in accordance with the invention utilized a blank of rolled plate steel, which is given the desired curved shape corresponding to the curvature of the leg. The blank is by means of pressing or extrusion in a suitable press tool formed with an outwardly extending brace stub at the desired angle, which brace stub is designed for welding to a complementary brace tubing in the frame work. Thereafter the blank with the brace stub is welded into the leg proper and will constitute a wall segment of the leg in the node. |
