Grid structure for an offshore construction, in particular an offshore wind energy converter

摘要

The grid structure has columns (12) and trusses (13) connected with each other at junctions (14, 16) and foot junctions (15), which are formed as foot junction parts (20) at lower ends of the columns. The foot junction parts are made of welding metal i.e. cast steel and are hollow shaped with round cross-section. Each foot junction part has a joint area for temporary welding of pipes (17, 18), where the joint area has a round or circular cross-section that corresponds to the pipes. Each foot junction part has an opened recess for an upper end region of a foundation pole (10).
