<p>To the base 1 of the footing an assembly member 3 is permanently fixed, having a form of multiple wall symmetrically formed along a-a axis, with a small recess 4 in the central zone, the walls of which from the upper view perspective are similar in shape to a circle or an ellipse, or a rectangle, or the combination thereof, open to the inside. From the ends of walls of the small recess 4, symmetrically sidewise, with an angle between 80 to 125° between them, socket walls 5 extend, creating a big recess 6 of trapezoid-like shape without bases, as a part of post socket 7. From ends of socket walls 5, assembly walls 8 extend perpendicularly to the symmetry axis a-a. Opposite the assembly member 3 a repeatedly bent, removable clamping member 10 is situated, having at both sides side-, perpendicular to a-a axis, fixing walls 11 connected by two curves 12, each of which is shaped along two sides of a triangle without a base, thus creating in the middle zone a triangular, open to the inside of the footing, big recess 13 as a second, complementary piece of post socket 7. At the other side of the clamping member 10 a meandric wall 14 is connected to it, which in an upper view perspective is a combination of open ellipses or rectangles, or circles, or the combination thereof, creating small recesses 15 between them.</p> |
