Abstract:
1. A joint assembly for controlling fractures along a fracture axis in a monolithic pour concrete structure defined by a first edge form section and a generally opposed second edge form section, the assembly comprising: an upper suspension line extending between the first edge form section and the second edge form section along the fracture axis, the upper suspension line defining a proximal end fixed to the first edge form section and a distal end fixed to the second edge form section; a fracture inducing sheath defining an elongate slit that exposes an upper internal channel defined by the sheath, the slit and the upper internal channel extending along the length of the sheath to define open ends thereof, and the upper suspension line traversing the upper internal channel to suspend the sheath within the concrete structure; and a lower suspension line extended between the first edge form section and the second edge form section along the fracture axis in parallel relation to the upper suspension line, the lower suspension line defining a proximal end fixed to the first edge form section and a distal end fixed to the second edge form section.
