Abstract
A single-use or multi-use prefabricated pier top form for topping a concrete pier comprises a hollow mold with an upper portion in the desired shape of the finished pier top, a stepped-down tapered mid portion, and a lower mating portion for mating with the pier form so that concrete can be continuously poured to fill both the pier form and the pier top form at one time. Use of the prefabricated pier top form results in substantial time and material savings because the top of the pier residing above ground can be formed at the same time as the footer and pier are formed replacing the need to form a separate pier top after the pier and footer have been filled with concrete.
Claims6
A structural pier form comprising:
- a prefabricated footer form configured to be backfilled with dirt having a tubular upper opening;
- a prefabricated tubular pier form having a lower opening and an upper opening, the lower opening coupled to the tubular upper opening of the prefabricated footer form;
- and
- a prefabricated pier top form comprising;
- a tubular lower section having a stepped mating area with multiple steps configured to mate several different sizes of the prefabricated tubular pier form and coupled to the upper opening of the prefabricated tubular pier form;
- a tapered mid-section that transitions outwardly from the lower section;
- and
- an upper section with walls extending from the tapered mid-section configured to create a shape of the top of the structural pier,
- wherein the walls of the upper section of the prefabricated pier top form create a shape at the top of the structural pier form different from the shape of the prefabricated tubular pier form.
A method for creating a structural pier comprising:
- creating a structural form assembly by setting a prefabricated footer form in the desired location;
- securing a prefabricated tubular pier form to the prefabricated footer form;
- securing a prefabricated pier top form to the prefabricated tubular pier form, the prefabricated pier top form comprising a tubular lower section having a stepped mating area with multiple steps designed to mate several different sizes of the prefabricated tubular pier form and configured to mate with the upper section of the prefabricated tubular pier form, a tapered mid-section that transitions outwardly from the lower section;
- and an upper section with walls extending from the tapered mid-section to create a shape that is a different than the tubular lower section of the pier top form;
- placing rebar within the structural form assembly;
- and
- filling the footer form, the pier form, and the pier top form with concrete in one pour.
