Verbindung für Bewehrungsstäbe und Verbindungsverfahren

摘要

A bar connection or splice and method uses a cage of relatively short bars which may be smaller reinforcing bars or threaded bars or rods. The bars of the cage may be joined by rings or wires and clamped to bridge or lap aligned bar ends. In one form, the concrete may be cast directly around the cage and bar ends to form the equivalent of a butt joined lap splice. In an enhanced form, the cage is included in a sleeve and set screws clamp the bars, cage and sleeve together. The sleeve may be filled with a hardenable matrix such as resin or grout, and then concrete is cast around the connection. The number of sets screws and bars of the cage may vary widely to form vertical and horizontal splices of axially aligned bar of the same or transitional sizes.
