System and method for constructing modular concrete ducts

摘要

Modular mold equipment for producing concrete culverts with tight tolerances. Modular mold equipment having a coupling plate is used to align and interconnect components of the mold. The components being aligned may have recesses for receiving the coupling plate. Modular mold equipment system with an extended size range to cover all standard concreted duct product sizes. Modular mold equipment having a pallet guide adjustment mechanism adapted for setting the pallet at a desired location in relation to a form. The desired location is based on a wall thickness of a concrete culvert to be produced. Modular mold equipment having a core that includes a core corner and another core component adapted to be coupled to the core corner, and locking apparatus adapted to lock the core corner to the other core component via a mechanism that extends outside the core.

1. A modular pallet of a mold for producing a concrete culvert with an opening located interior of an outer wall of the concrete culvert, said pallet comprising:
a corner component; a forming surface of the corner component assisting with the formation of the outer wall of a first thickness; a wall adapter component attachable to the corner component to extend outward from the corner component away from the opening to increase the thickness of the outer wall of said concrete culvert produced by said modular pallet; a forming surface of the wall adapter component that increases the thickness of the outer wall formed by the corner component; a coupling plate aligning the forming surface of the wall adapter component exterior to the forming surface of the corner component when securing the corner component and the wall adapter component; a recess of the corner component configured to receive the coupling plate; a recess of the wall adapter component configured to receive the coupling plate; and the coupling plate securing the wall adapter component exterior to the corner component.
