Pile for Foundation

Abstract

The device includes the body ( 1 ), provided with a helix ( 3 ) on the bottom end, and of an ending ( 4 ) on the top part of the body ( 1 ). The diameter of the helix ( 3 ) is in the range of 1.0 to 100 times the diameter of the body ( 1 ) and/or of the least transversal dimension of the body ( 1 ). The body ( 1 ) has a closed or open profile on the cross section, with the body ( 1 ) having one profile at least. The pitch of the helix ( 3 ) is in the range of 0.1% to 90% with the pitch being linear or variable along the length of the helix and the length of the blade of the helix ( 3 ) being 5° at least of the circumference of the body ( 1 ) and the drilling base being provided with one helix ( 3 ) at least. On the bottom end, the body is provided with a pricker ( 2 ), with the pricker ( 2 ) being bevelled into one surface at least on the bottom end at the angel in the range of 90° to 0.1° towards the vertical axis of the drilling base and/or with the bottom end of the pricker ( 2 ) having a semi-spherical shape.

         18 . A pile for a foundation comprising:
 a body having a bottom end and a top end, at least one helix provided on the bottom end of the body, the top end including an ending;   wherein the helix has an blade having a diameter and the body has a diameter and/or least transversal dimension, the diameter of the helix being between about 1.0 to 100 times the diameter and/or least transversal dimension of the body, and   wherein the body has a cross-section and a closed or open profile on the cross-section, the body having at least one profile, and   wherein the pitch of the helix is in the range of 0.1% to 90%, with the pitch being linear or variable in the length of the helix, and   wherein the length of the blade of the helix is at least 5° of the circumference of the body, and   wherein the body has a surface which is eventually provided with a wire above the helix, with said wire being shaped to form a thread on the surface of the body, and   wherein the surface of the body is provided with the wire below the helix, with said wire being shaped to form a thread on the surface of the body.   
     
     
         19 . A pile for a foundation according to  claim 18 , wherein the body is provided with a pricker on the bottom end, with the pricker being bevelled into one surface at least on the bottom part, with an angle of said bevelled surface being in the range of 90° to 0.1° toward the vertical axis of the drilling base. 
     
     
         20 . A pile for a foundation according to  claim 18 , wherein the body is provided with a pricker on the bottom end, and wherein the bottom part of the pricker has a semi-spherical shape. 
     
     
         21 . A pile for a foundation according to  claim 18 , wherein the pile is provided with an auxiliary ring on the top end of the body below the ending. 
     
     
         22 . A pile for a foundation according to  claim 18 , wherein the ending is provided with a rectification bracket. 
     
     
         23 . A pile for a foundation according to  claim 22 , wherein the rectification bracket is shaped as a nut. 
     
     
         24 . A pile for a foundation according to  claim 18 , wherein the ending is shaped as a tube. 
     
     
         25 . A pile for a foundation according to  claim 18 , wherein the ending is shaped as a flange. 
     
     
         26 . A pile for a foundation according to  claim 18 , wherein the bottom end of the body has a smaller diameter than the top end of the body, and wherein an auxiliary helix is located on a transition between the bottom end and the top end.
