Abstract:
A method of forming contraction joints in an end facing of poured concrete structures that aesthetically simulate the appearance of juxtaposed units of precast concrete, said method comprising the steps of:a) providing a form board having a surface profile of said end face to be formed;b) providing at least one substantially T-shaped blade-like insert rearwardly configured to generally correspond to the surface profile of the provided form board and including a laterally extending blade, said blade being solid of substantially uniform lateral depth on the order of between about 5/8-1 inches and of a flat substantially uniform transverse width of about 1/4 inch;c) attaching said insert to the profile surface of the form board for the blade of the insert to extend laterally away therefrom;d) mounting the form board with said attached insert at a location at which an end-face of poured aggregate is to be formed;e) pouring aggregate against said mounted form board; andf) after the curing of said aggregate, removing said form board with attached blade-like insert from the end face whereby to expose a contraction joint in the end face at the location of said removed insert that aesthetically simulates the appearance of juxtaposed units of precast concrete.
