Shore post leg assembly

Abstract

A a metal shore post of a concrete forming assembly is disclosed. An outer telescoping tube is provided that has a main section with a first inside diameter and top portion with a section having a second inside diameter reduced relative to the first inside diameter of the outer tube. An inner telescoping tube is inserted for telescopic movement inside the outer tube. After assembly, a pair of pistons are inserted through access holes in the outer tube to provide a crushing force to the inner tube deforming it to create a region of increased diameter that is greater than that of the reduced diameter section but not so large as to prevent telescopic movement of the inner tube inside the outer tube. The increased dimension region thereby prevents accidental separation of the inner tube from the assembly, thereby improving safety and efficiency. Openings are provided in the inner tube in the region being crushed in order to control the region of deformation.

1 . A metal concrete forming apparatus assembly, comprising:
 (a) an outer telescoping tube having an inside diameter and a first end portion with a section having an inside diameter reduced relative to the inside diameter of the outer tube;   (b) an inner telescoping tube having an end portion received for telescopic movement inside the outer tube; and   (c) a deformed region of the end portion of the inner tube having an enlarged dimension that is less than the inside diameter of the outer tube and greater than the inside diameter of the reduced diameter section.   
     
     
         2 . A metal concrete forming apparatus assembly as defined in  claim 1 , further comprising a concrete forming apparatus component attached to an opposite, second end portion of the outer tube.
