Base For Support Foot With High Strength For Supporting Heavy Bodies

Abstract

A base (110) for a support foot (100) for supporting heavy bodies on a support surface, comprising a cap (115) intended in the use to be mechanically coupled to coupling means (105) of the base to a body to be supported. The cap is made of a first material of mechanical properties such as to guarantee that the cap is able to support, remaining substantially within the limit of elastic deformability, a first significative fraction of a load received by said coupling means to the body to be supported, and has said concavity on the side that, in the use, faces the support surface. A synthetic material mass (210) is arranged in adhesion to the cap and it is adapted to substantially fill the concavity of the cap, forming a contact surface (215) with a support surface. A support frame (240), buried within the synthetic material mass, is made of a second material having mechanical properties comparable to that of the cap, such as to guarantee that the support frame can support, remaining substantially within the limit of the elastic deformability, a second significative fraction of said load, wherein the first and second fractions of the load form altogether substantially the total load.
