Pre-stressed concrete foundation for a marine building structure

Abstract

A pre-stressed marine foundation includes a concrete base to be placed on a sea bed, a body placed over the concrete base, and a concrete platform. The body includes closed sections, each closed section composed of a pre-stressed concrete segmented column that has an upper extreme and a lower extreme joined at the base, and opened sections joined at sides of the closed sections, each open section composed of a structured beam frame. The concrete platform is joined at the upper extremes of the concrete columns.

1 . A pre-stressed marine foundation, comprising:
 a concrete base to be placed on a sea bed,   a body placed over the concrete base, the body including:
 a plurality of closed sections, each closed section composed of a pre-stressed concrete segmented column, each column having an upper extreme and a lower extreme joined at the base, and 
 a plurality of opened sections joined at sides of the closed sections, each open section composed of a structured beam frame, and 
   a concrete platform joined at the upper extremes of the concrete columns.   
     
     
         2 . The foundation of  claim 1 , wherein the body has a triangular cross-section formed by three segmented pre-stressed concrete columns and three beam frames therebetween. 
     
     
         3 . The foundation of  claim 1 , wherein each beam frame includes a plurality of beams selected from concrete beams or metallic beams. 
     
     
         4 . The foundation of  claim 1 , wherein concrete segments forming each of the concrete columns are semicircular and have substantially the same form and same dimensions. 
     
     
         5 . The foundation of  claim 1 , wherein the base includes an aperture. 
     
     
         6 . The foundation of  claim 1 , further comprising a concrete layer added to the base to increase weight of the base. 
     
     
         7 . A pre-stressed marine foundation, comprising:
 a concrete base,   a body placed on the concrete base, the body having a triangular cross-section formed by three equally-spaced segmented pre-stressed vertical concrete columns with three beam frames joined in an open space between the three spaced segmented vertical concrete columns, and   a concrete platform joined to upper ends of the vertical concrete columns.   
     
     
         8 . The foundation of  claim 7 , wherein the base has a bottom diameter and a top diameter and a sloped side surface, the bottom diameter greater than the top diameter. 
     
     
         9 . The foundation of  claim 7 , wherein the base top diameter is approximately the same diameter of the body. 
     
     
         10 . The foundation of  claim 7 , wherein the base includes a central triangular aperture. 
     
     
         11 . The foundation of  claim 7 , wherein each beam frame includes a plurality of structured beams selected from concrete beams or metallic beams. 
     
     
         12 . The foundation of  claim 7 , wherein concrete segments forming each of the vertical concrete columns are semicircular and have substantially the same form and same dimensions. 
     
     
         13 . A pre-stressed marine foundation, comprising:
 a base having a sloped side surface,   a tower placed on the base, the tower having a triangular cross-section formed by a plurality of spaced segmented pre-stressed vertical concrete columns with a plurality of reinforcing beam frames joined in open spaces between the spaced segmented vertical concrete columns to realize a tower with annular structure and said triangular cross-section, and   a platform joined to upper ends of the vertical concrete columns.   
     
     
         14 . The foundation of  claim 13 , wherein the base includes a central triangular aperture. 
     
     
         15 . The foundation of  claim 13 , wherein each beam frame includes a plurality of structured beams selected from concrete beams or metallic beams. 
     
     
         16 . The foundation of  claim 13 , wherein concrete segments forming each of the vertical concrete columns are semicircular and have substantially the same form and same dimensions. 
     
     
         17 . The foundation of  claim 13 , further comprising a concrete layer added to the base to increase weight of the base.
