Abstract
An injection driver assembly may be used to install hollow bar bolts. The injection driver assembly may include a socket that can be rotated to drive hollow bar bolts into a wall or other structure. The injection driver assembly may also include a housing assembly that allows hardening product to be injected into a hollow bar bolt while the socket is positioned overtop the hollow bar bolt and remains capable of rotating.
Claims20
An injection driver assembly comprising:
- a socket that is configured to rotate a hollow bar bolt;
- a driver that is coupled to the socket and configured to rotate the socket;
- and
- a housing assembly that is positioned around the driver and configured to enable the socket and driver to rotate relative to the housing assembly;
- wherein the housing assembly, the driver, and the socket form a pathway for injecting a hardening product into the hollow bar bolt while the hollow bar bolt is positioned within the socket.
An injection driver assembly comprising:
- a socket having a distal opening that is configured to drive a hollow bar bolt and a proximal opening, the proximal opening being open to the distal opening;
- a driver that is secured to the socket, the driver forming a longitudinal channel that is open to the distal opening of the socket and one or more cross channels that extend between an outer surface of the driver and the longitudinal channel;
- and
- a housing assembly that is positioned around the driver and configured to enable the socket and driver to rotate relative to the housing assembly, the housing assembly having a housing with one or more injection openings that are open to the one or more cross channels such that fluid or material injected through the one or more injection openings can pass into a hollow bar bolt that is positioned within the distal opening of the socket.
A method for installing a hollow bar bolt comprising:
- positioning an injection driver assembly to drive the hollow bar bolt, the injection driver assembly comprising:
- a socket that is configured to receive a nut of the hollow bar bolt;
- a driver that is coupled to the socket and configured to rotate the socket;
- and
- a housing assembly that is positioned around the driver and configured to enable the socket and driver to rotate relative to the housing assembly;
- while the nut is positioned within the socket, injecting a hardening product into a pathway formed through the housing assembly, the driver and the socket to cause the hardening product to be injected into the hollow bar bolt;
- and
- rotating the driver and socket relative to the housing assembly while the nut is positioned within the socket and after the hardening product has been injected to thereby drive the hollow bar bolt until a desired tension has been reached.
