Foundation footing

Abstract

The foundation footing consists of a vertically arranged tubular element (2) terminated at the bottom by a pointed element (5). The tubular element (2) has a sliding element (7) located within it. The tubular element (2) has a cross-sectional shape close to a rectangle, the shorter side of which is a semicircle in the shape of a circle, containing two sliding plate elements (7) in the shape of rectangular plates, and the internal dimension of the tubular element is slightly larger than the cross-section of the sliding tubular element (7). Furthermore, the tubular element (2) terminates at the bottom with a three-dimensional spearhead (5), which consists of two plates, the first plate and the second plate, placed perpendicular to each other, the relative positions of which are determined by cutouts for the first plate and the second plate.Furthermore, the tubular element (2) has ribs (3) located on both sides of the tubular element (2), extending to the lower edge of the tubular element (2) and being perpendicular to the longer side of the tubular element (2), wherein the ribs (3) engage in a cutout of the second plate and are permanently connected thereto. The shorter sides of the tubular element (2) engage in cutouts of the first plate and are permanently connected thereto, while the tubular element (2) rests on a shelf in the cutout of the second plate and is spaced from the bottom of the cutout by a distance enabling the sliding element (7) to be extended.
