Foundation structure for constructions

A foundation structure for constructions comprising:

• a footing structure, which is designed to be buried to transfer and releasing stresses of a superstructure of a construction to the ground;
• and
• mechanical connection elements firmly fastened to said footing structure to be able to structurally fasten the superstructure of the construction to said footing structure;
• wherein:
• said footing structure is mostly defined by a gabion structure filled with inert material and designed to be placed in a foundation excavation, to thereby define a dry foundation system substantially free of any mass casting;
• said gabion structure comprises an upper side, designed to face the superstructure to be supported, which forms a closing panel of said gabion structure;
• said mechanical connection elements are firmly fastened to said gabion structure and project upwards from said upper side of said gabion structure;
• wherein said mechanical connection elements are firmly fastened to said gabion structure by means of tie rods and/or metal rings;
• and
• wherein said tie rods engage said gabion structure with a first end, wherein:
• said first end of said tie rods engages a lower portion of said gabion structure;
• and/or
• said first end of said tie rods defines a hook portion, a folded portion or a flange to be held in position by said gabion structure and/or by the inert material above said first end of said tie rods.

• said mechanical connection elements are firmly fastened to said gabion structure and project upwards from said upper side of said gabion structure;
• wherein said mechanical connection elements comprise:
• a base plate having a predetermined thickness and designed to be fastened to said footing structure,
• a bracing beam designed to act as a support for the superstructure,
• a connecting bar having a lower end fastened to said base plate and a distal end fastened to said bracing beam by adjustable fastening means, to thereby allow adjustment of a distance of said distal end from said lower end, and
• a hardened layer made of a hardenable material said connecting bar being at least partially embedded therein,
• said hardened layer contacting said bracing beam and said base plate to cooperate with said connecting bar in transferring and distributing loads from said bracing beam to said base plate.

A method of making a foundation structure for a constructions, comprising the steps of:

• forming a foundation excavation;
• making a footing structure for foundations in said foundation excavation and
• providing mechanical connection elements firmly fastened to said footing structure to be able to structurally fasten said footing structure to a superstructure of the construction,
• wherein said footing structure is mostly defined by a gabion structure filled with inert material and designed to be placed in said foundation excavation, to thereby define a dry foundation system substantially free of any mass casting, wherein said method comprising the steps of:
• positioning said gabion structure, filled with inert material, vibrated and closed by a base plate with a connecting bar installed, in said foundation excavation and
• mechanically connecting said gabion structure to a bracing beam designed to act as a support for the superstructure, by said mechanical connection elements;
• wherein said foundation structure is a foundation structure having the footing structure, which is designed to be buried to transfer and release stresses of the superstructure of the construction to the ground, and the mechanical connection elements are firmly fastened to said footing structure to be able to structurally fasten the superstructure of the construction to said footing structure, wherein the gabion structure comprises an upper side, designed to face the superstructure to be supported, which forms a closing panel of the gabion structure and the mechanical connection elements are firmly fastened to said gabion structure and project upwards from said upper side of said gabion structure;
• wherein said step of mechanically connecting said gabion structure to the bracing beam by the mechanical connection elements comprises the steps of:
• providing said base plate having the connecting bar inserted in a through hole and a housing seat closed by the closing panel;
• placing said base plate over said gabion structure;
• fastening said base plate to said gabion structure by means of tie rods;
• providing the bracing beam in a desired position and at a desired height, by supporting the bracing beam with a temporary auxiliary support structure;
• firmly fastening said connecting bar to said bracing beam by acting on an adjustable fastening means, until a head of said connecting bar abuts against a lower side of said base plate, and
• casting a hardenable material into a formwork until it reaches at least a lower height of said bracing beam.
