<p>The structure has frame shaped units (1) with U-shaped parts (2, 3) placed at 90 degrees with respect to each other and having different heights. The U-shaped parts of the frame shaped units are formed from tube sections (4) and corner connections (5, 6) for permitting the U-shaped parts to rest on ground along a positioning direction to obtain a goal with different heights. The tube sections and the corner connections are made of aluminum, where the heights of the U-shaped parts are 1.80 and 1.40 meters, respectively.</p> |
