Abstract: Systems, methods, and devices for supporting a concrete substrate and providing temperature control are disclosed. The system includes a supporting member and a temperature control device. The supporting member includes a concrete substrate and at least a first bar disposed within the concrete substrate. The first bar defines a channel longitudinally extending from the first end to the second end. The first bar has a first cross-sectional area as measured in a plane that is perpendicular to the longitudinal axis that is greater than or equal to a cross-sectional area requirement of a solid bar disposed within the concrete substrate under Building Code Requirements (e.g., ACI 318). The temperature control device is coupled to the first bar and is configured to control the temperature of the concrete substrate.

Abstract: A device for reinforcing concrete. The device is of one-piece construction and includes a perforate load-bearing member with first and second surfaces around which concrete can be placed. Apertures in the perforate load-bearing member form connectivity points between concrete disposed on the first and second surfaces to promote bonding of the concrete such that a contiguous mass of concrete forms upon curing. In various embodiments, the device can be configured as a joint, beam, shear wall, retaining wall or footer. In addition, the device can be prefabricated, thereby reducing the time and cost of formation of a reinforced concrete structural member.

Abstract: A device for reinforcing concrete. The device includes a perforate load-bearing member with first and second surfaces around which concrete can be placed. Apertures in the perforate load-bearing member form connectivity points between concrete disposed on the first and second surfaces to promote bonding of the concrete such that a contiguous mass of concrete forms upon curing. The resulting reinforced concrete structure is of integral construction. In one embodiment, the device can be configured as cage-like structure. In addition, the device may define a unitary structure that can be prefabricated, thereby reducing the time and cost of formation of a reinforced concrete structural member.
