Concrete Form Assembly for Square Columns, and Locating Template for Use Therewith

Abstract

A locating template for a non-round concrete form of the type having a round outer tube and an insert assembly installed in the outer tube for defining the desired non-round shape. The locating template can be fit into the end of the channel defined by the insert assembly. The locating template has a crosshair or series of marks indicating the center of the locating template, which corresponds to the center of the channel defined by the insert assembly. The contractor simply marks the outer surface of the outer tube at two or more locations aligned with the crosshair or marks on the locating template. The locating template is removed, and the form is set up on the ground with the marks on the outer tube aligned with the crosshair on the ground. The column can then be poured in the usual manner.

       2 . The concrete form assembly of  claim 1 , wherein the non-round shape of the first locating template is square or rectangular having four sides, and the indicators are arranged to indicate a location for each of the four sides of the first locating template at which said side is bisected. 
   
   
       3 . The concrete form assembly of  claim 1 , wherein the first locating template has an outer face substantially normal to a central longitudinal axis of the form and facing away from an interior of the form, and an opposite inner face, a thickness of the first locating template being defined between the outer and inner faces. 
   
   
       4 . The concrete form assembly of  claim 3 , and wherein at least one of the indicators is at or on the outer face. 
   
   
       5 . The concrete form assembly of  claim 3 , wherein the indicators comprise straight grooves formed in the outer face. 
   
   
       6 . The concrete form assembly of  claim 3 , wherein the indicators comprise straight lines printed or marked on the outer face. 
   
   
       7 . The concrete form assembly of  claim 3 , wherein one of the indicators comprises a slot formed entirely through the thickness of the first locating template and extending from the outer peripheral surface at one side of the first locating template partway toward an opposite side thereof. 
   
   
       8 . The concrete form assembly of  claim 7 , wherein the first locating template defines an aperture extending through the thickness. 
   
   
       9 . The concrete form assembly of  claim 8 , wherein the aperture is positioned generally centrally in the first locating template and the slot extends to and connects with the aperture. 
   
   
       10 . The concrete form assembly of  claim 3 , wherein at least some of the indicators comprise notches formed in the outer peripheral surface of the first locating template. 
   
   
       11 . The concrete form assembly of  claim 3 , wherein the first locating template defines an aperture extending through the thickness. 
   
   
       12 . The concrete form assembly of  claim 11 , wherein at least some of the indicators comprise notches formed in the outer peripheral surface of the first locating template. 
   
   
       13 . The concrete form assembly of  claim 1 , further comprising a second locating template substantially identical to the first locating template and positioned in the second opening of the channel. 
   
   
       14 . The concrete form assembly of  claim 1 , wherein the first locating template is made of polymer foam. 
   
   
       15 . A device for use with a concrete form for forming a non-round concrete column, the form having a circular cylindrical outer surface and having an inner surface defining a central channel of non-round cross-section for defining the desired cross-section for a concrete column, the channel defining a first opening of non-round shape at one end of the form and an opposite second opening of non-round shape at an opposite end of the form, the device comprising:
 a first locating template configured to be inserted into either of the first and second openings of the channel, the first locating template including an outer peripheral for frictionally engaging an inner surface of the form at the first opening so as to retain the first locating template in the first opening, and the first locating template defining a plurality of indicators that are visually discernable when the first locating template is positioned in the first opening, the indicators indicating a geometric center of the first locating template and thus of the first opening.   
   
   
       16 . The device of  claim 15 , wherein the non-round shape of the first locating template is square or rectangular having four sides, and the indicators are arranged to indicate a location for each of the four sides of the first locating template at which said side is bisected. 
   
   
       17 . The device of  claim 15 , wherein the first locating template has an outer face substantially normal to a central longitudinal axis of the form and facing away from an interior of the form, and an opposite inner face, a thickness of the first locating template being defined between the outer and inner faces. 
   
   
       18 . The device of  claim 17 , and wherein at least one of the indicators is at or on the outer face. 
   
   
       19 . The device of  claim 17 , wherein the indicators comprise straight grooves formed in the outer face. 
   
   
       20 . The device of  claim 17 , wherein the indicators comprise straight lines printed or marked on the outer face. 
   
   
       21 . The device of  claim 17 , wherein one of the indicators comprises a slot formed entirely through the thickness of the first locating template and extending from the outer peripheral surface at one side of the first locating template partway toward an opposite side thereof.
