The system has two link attachment extensions non-rotatably longitudinally guided on an inclined beam (2) and permanently attached to the inclined beam at standard positions. A column (1) is pivotably connectable to one of link attachment extensions, and a brace (3) is pivotably connectable to another link attachment extension. The column, the inclined beam and the brace are combined to form a permanently adjustable support stand in the form of a triangular truss. A link joint (70) is provided between the inclined beam and the column. An independent claim is also included for a method of assembling an erection system for a support stand of a photovoltaic open-space installation. |
