Abstract
Connecting reinforcing bars in an access hole by a method and means which comprises: (1) securing to each first bar by a radial compression the unthreaded portion of a first partially internally threaded sleeve, (2) securing to each end of a connecting bar the unthreaded portion of a second partially internally threaded sleeve, the connecting bar being of a length slightly less than that between the sides of the hole, (3) locating in the threaded portion of the second sleeves at each end of the connecting bar a threaded high tensile externally threaded stud and locating the connecting bar between the first bars in the sides of the hole, (4) rotating each stud to engage a threaded sleeve secured to a first bar so to bridge the gap between the first bars by means of the connecting bar.
