Patent ID: 8550419

Claim:
An erection system for a photovoltaic open-space installation support stand, each support stand comprising a column ( 1 ) to be driven into the ground and an inclined beam ( 2 ), and a brace ( 3 ) to brace the inclined beam ( 2 ) obliquely downward against the column ( 1 ), wherein the column ( 1 ), the inclined beam ( 2 ), and the brace ( 3 ) can be combined into a firmly adjustable support stand in the form of a triangular truss, and to this end a first link joint ( 20 ) is disposed between inclined beam ( 2 ) and column ( 1 ), a second link joint ( 70 ) is disposed between inclined beam ( 2 ) and brace ( 3 ), and a third link joint ( 90 ) is disposed between brace ( 3 ) and column ( 1 ), and the first link joint ( 20 ) comprises a first link attachment extension ( 25 ), and the second link joint ( 70 ) comprises a second link attachment extension ( 72 ), and the two link attachment extensions ( 25 , 72 ) are able to be disposed on and be longitudinally guided by the inclined beam ( 2 ), characterized in that an assembly group comprising the inclined beam ( 2 ) and the two link attachment extensions ( 25 , 72 ) is assembled, wherein the two link attachment extensions ( 25 , 72 ) are nonrotatably longitudinally guided on the inclined beam ( 2 ) and permanently attached there at standard positions, and that the column ( 1 ) is pivotably connectable to the first link attachment extension ( 25 ) and the brace ( 3 ) is pivotably connectable to the second link attachment extension ( 72 ), wherein at least one of the two link attachment extensions ( 25 , 72 ) has a link section ( 54 , 74 ) to support a hinge pin ( 24 , 81 ), wherein the link section ( 54 , 74 ) is disposed such that the rotational axis ( 21 , 71 ) of a hinge pin ( 24 , 81 ) supported there crosses the inclined beam ( 2 ) externally, wherein the link section ( 54 , 74 ) of at least one link attachment extension ( 25 , 72 ) is designed in a U-profile shape, and wherein at least one of the two link attachment extensions ( 25 , 72 ) is designed in an H-profile shape, wherein the shape of the link attachment extension ( 25 , 72 ) results from the U-profile-shaped link section ( 54 , 72 ) and an U-profile-shaped attachment section ( 53 , 73 ).
