Abstract

A caisson tube finishing form includes a contact surface adapted and constructed to be secured to a caisson tube. A form surface is adapted and constructed to extend inwardly from an inner surface of the caisson tube. The form surface is in contact with concrete poured into the caisson tube during use thereof, and produces an aesthetically pleasing outer surface for the structural element resulting from use of the caisson tube.

1 . A caisson tube finishing form comprising the following:
 a contact surface adapted and constructed to be secured to a caisson tube; and   a form surface adapted and constructed to extend inwardly from an inner surface of the caisson tube, the form surface being in contact with concrete poured into the caisson tube during use thereof.   
   
   
       2 . A caisson tube finishing form in accordance with  claim 1 , wherein the contact surface is adapted and constructed to be secured to an interior surface of the caisson tube. 
   
   
       3 . A caisson tube finishing form in accordance with  claim 1 , wherein the contact surface comprises a generally circular ring. 
   
   
       4 . A caisson tube finishing form in accordance with  claim 3 , wherein the contact surface has sufficient height to be self-leveling within the caisson tube. 
   
   
       5 . A caisson tube finishing form accordance with  claim 3 , wherein the form surface comprises an annular frustoconical surface. 
   
   
       6 . A caisson tube finishing form in accordance with  claim 1 , wherein the caisson tube finishing form has a generally triangular cross-sectional shape. 
   
   
       7 . A caisson tube finishing form in accordance with  claim 1 , wherein the caisson tube finishing form has a generally V-shaped cross-sectional shape. 
   
   
       8 . A caisson tube finishing form in accordance with  claim 1 , wherein the form surface is provided with at least one decorative surface ornament element. 
   
   
       9 . A caisson tube finishing form in accordance with  claim 1 , wherein the caisson tube finishing form is fabricated from a plastic material.
