Abstract:
Various embodiments provide a concrete slab joint stabilizer including an expandable housing including a cylinder defining a slit running along its longitudinal length, the expandable housing having a housing axis extending longitudinally there through, and an expander configured to expand the expandable housing in directions perpendicular to the housing axis. The concrete slab joint stabilizer is configured to limit relative vertical displacement between two adjacent concrete slabs.

Claim (Index 14):
A concrete slab joint stabilizer comprising:\n an expandable housing including a wall defining a slit running along its longitudinal length, the expandable housing having a longitudinal central opening and a housing axis extending longitudinally there through; and an expander configured to expand the expandable housing uniformly in directions perpendicular to the housing axis, the expander including:\n a compressible tube in the expandable housing, \n a cap partly in the expandable housing, \n a bolt positioned in the compressible tube, the bolt having a head and a threaded end portion connected to the head, \n a nut engagable with the threaded end portion of the bolt, the nut rotatably fixed relative to the expandable housing to prevent the nut from rotating in the expandable housing while enabling the nut to slide longitudinally in the expandable housing, \n a pin connected to and extending transversely from the nut to rotatably fix the nut relative in the expandable housing, and \n at least one washer between the nut and the compressible tube, \n wherein turning the bolt in one direction causes the nut to move toward the head of the bolt, thereby compressing the compressible tube longitudinally forcing it to expand radially, and \n wherein turning the bolt in an opposite direction causes the nut to move away from the head, thereby uncompressing the compressible tube.
