Abstract
A nut for threading onto a reinforcing bar, wherein the nut includes a female thread for threading onto a male thread of the reinforcing bar, wherein the nut includes a port arranged such that, when the nut is in situ on the reinforcing bar the port provides a passage for injection of fluid material to flow into a cavity defined by an external surface of the reinforcing bar and an internal surface of the nut.
Claims16
A nut assembly for threading onto a reinforcing bar, wherein the nut assembly comprises:
- a nut including:
- a female thread for threading onto a male thread of the reinforcing bar;
- a port positioned such that, when the nut is on the reinforcing bar, the port provides a passage for injection of fluid material to flow into a cavity defined by an external surface of the reinforcing bar and an internal surface of the nut;
- and
- a cap configured to cover the port.
An assembly comprising:
- a reinforcing bar;
- a nut threadable onto the reinforcing bar such that an internal thread of the nut engages with a corresponding external thread of the reinforcing bar, wherein the nut includes a port positioned such that, when the nut is threaded on the reinforcing bar, the port provides a passage for injection of fluid material to flow into a cavity defined by an external surface of the reinforcing bar and an internal surface of the nut;
- and
- a cap configured to cover the port.
A method of securing a nut on a reinforcing bar, the method comprising:
- threading the nut onto the reinforcing bar such that an internal thread of the nut is threaded onto an external thread of the reinforcing bar;
- rotating the nut to locate the nut in a desired position along a length of the reinforcing bar;
- injecting settable material through a port of the nut such that the settable material flows into a cavity between an external surface of the reinforcing bar and an internal surface of the nut;
- and
- observing a second port opposite the first port to determine when sufficient settable material has been injected through the first port, and ceasing injection of the settable material after observing sufficient settable material through the second port.
A nut for threading onto a reinforcing bar, wherein the nut comprises:
- a female thread configured to be threaded onto a male thread of the reinforcing bar;
- a first port positioned such that, when the nut is on the reinforcing bar, the first port provides a first passage for injection of fluid material to flow into a first cavity defined by an external surface of the reinforcing bar and an internal surface of the nut;
- and
- a second port positioned such that, when the nut is on the reinforcing bar, the second port provides a second passage for injection of fluid material to flow into a second cavity defined by the external surface of the reinforcing bar and the internal surface of the nut.
