         6 . The system according to  claim 2 , wherein said first four ducts arranged in a cross-shaped pattern can be closed selectively, in particular at a side of said feet that is not directly connected to other feet, as in the case of said feet located on an outer perimeter of said ventilated crawl space or interspace or elevated platform, by means of partitions which are constituted by an arced front wall, with a width and height greater than a diameter of said first four ducts. 
     
     
         7 . The system according to  claim 6 , wherein a cylindrical ridge protrudes from a concave surface of the arced front wall of said partition and has a smaller diameter than said first four ducts so as to make it possible to achieve a hermetic connection for the concrete that will be poured. 
     
     
         8 . The system according to  claim 6 , wherein two teeth protrude axially at an inner perimetric edge of each of said first four ducts that lies substantially at said overlying fifth duct and have a chosen shape and are arranged diametrically with respect to each other, said two teeth having a first function, which is to act as a blocking element during the insertion of said second interconnection means at one of said first four ducts. 
     
     
         9 . The system according to  claim 8 , wherein said partition has, at said cylindrical ridge, two notches, which are provided diametrically with respect to each other and are arranged so that said two teeth can be accommodated therein once said partition has been inserted in one of said first four ducts. 
     
     
         10 . The system according to  claim 9 , wherein one or more elastically deformable claws protrude from said concave surface of said arced front wall of said partition, in a region below each of said notches, and have an axial extension such as to allow snap interconnection with said teeth, which have a second function, which is to obtain an interconnection of said partitions with said first four ducts. 
     
     
         11 . The system according to  claim 2 , wherein said second interconnection means, associable with each of said feet, are constituted by a tube of such dimensions as to make it possible to mutually interconnect two of said feet which are mutually adjacent. 
     
     
         12 . The system according to  claim 11 , wherein once said first and second interconnection means, constituted by said feet and said tube, are installed, and thus when said lower ends of said supporting tubes are associated with said fifth ducts of said feet and said tubes are associated with said first four ducts of said feet, a channeled receptacle is defined which communicates also with the upper ends of said supporting tubes with which said formwork elements are associated, each of said channeled receptacles extending within each of said supporting tubes of each one of said feet and of said tubes. 
     
     
         13 . The system according to  claim 11 , wherein said tube mutually connects two of said first four ducts arranged mutually adjacent and in mutual axial alignment, so as to define, together with the positioning of said supporting tubes at said fifth ducts, a shape structure that allows, together with the coupling of said formwork elements to an edge of an upper end of a supporting tube and with the pouring of concrete, the formation of the concrete structure of said ventilated crawl space or interspace or elevated platform, which comprises the formation of a beam for connection between said supporting tubes. 
     
     
         14 . The system according to  claim 11 , wherein in a condition in which one of said tubes is associated with one of said first four ducts, a clearance is defined between one end of said tube and said two teeth, said clearance being obtained by cutting one of said ends of said tube by the desired extent. 
     
     
         15 . The system according to  claim 11 , further comprising second holes, provided in said first four ducts on an opposite side with respect to said base, which allow an installer to visualize a placement of the ends of said tubes arranged within said first four ducts. 
     
     
         16 . A method of assembling said ventilated crawl space or interspace or elevated platform according to  claim 1 , wherein:
 initially said first interconnection means are placed on a foundation or surface,   one tube of a plurality of tubes is positioned between two of said feet which are adjacent, at at least two of first four ducts,   a duct, of said first four ducts, that is not affected by one of said tubes is closed by means of one of a plurality of partition,   said partitions, where necessary, are inserted from above and from within said first interconnection means, where the partitions are guided into a correct position for closing a desired duct of said first four ducts by a shape of a front wall, which is arced, and by the presence of teeth and by notches and by claws,   supporting tubes are positioned at said fifth ducts, which are directed upward, of the first interconnection means on which a dome-shaped formwork elements will be placed,   concrete is poured at a channeled receptacle thus obtained.
