Junction Node of Truss for Offshore Wind Power Generation Plant

The present invention is one of the host that the first and second tube (3) is in connection for the truss that is turned by a tilting each center angle from the center line of the hollow host (1) branch node, the first and second branch pipe is connected to first and second risers to be formed symmetrically on the side toward the first and second branch pipes (5, riser); Formed extends in a columnar shape on the first and second riser, each supporting member 7; The insertion portion (9) is fastened on the sphere are respectively inserted into the first and second branch pipe at an end of the support; The first and second plane of symmetry (11) riser is in contact with each other, form the vertical surface (13) with respect to the host, the angle which the vertical plane forms with the support portion 90 - constitutes the center angle, wherein the branch node in the casting step minutes of the truss which is produced by relates to a base node.
