Abstract
Devices and methods for forming voids or cavities in concrete such that reinforcing bars can be used to connect different pours of concrete, the devices including an insert having a base and an elongate member extending from the base, and the method including coupling the insert to formwork, pouring concrete into the formwork, which surrounds the insert, allowing the concrete to partially cure, such that it retains its shape, removing the formwork and insert to form a void in the partially cured concrete, inserting a reinforcing bar into the void, applying adhesive to adhere the reinforcing bar to the concrete, and pouring concrete around the reinforcing bar, such that the reinforcing bar joins the two pours of concrete together via the void and adhesive.
Claims11
A device for forming a void in concrete, comprising:
- a single base having a square shape with opposing flat and planar surfaces and a plurality of holes through the opposing flat and planar surfaces, each of the holes having a size and a shape to receive a fastener for coupling the base to a piece of formwork, the base having a width;
- and
- a single elongate member extending perpendicular from the base and centered with respect to the base as a single, unitary, integral component with the base, the elongate member having a shape and a size to create the void when the concrete cures around the elongate member and the elongate member is removed from the cured concrete, the void having a size and a shape to receive a reinforcing bar, the elongate member having a length greater than the width of the base and wherein the elongate member is a solid body having a constant circular cross section along an entire length of the elongate member.
A device for forming a void in concrete, comprising:

- and
- a single elongate member including only a single solid body and being a single rod extending perpendicular from the base and centered with respect to the base as a single, unitary, integral component with the base, the elongate member having a shape and a size to create the void when the concrete cures around the elongate member and the elongate member is removed from the cured concrete, the void having a size and a shape to receive a reinforcing bar, the elongate member having a length greater than the width of the base and a constant and continuous circular cross section along an entire length of the elongate member.
