  • Patent number: 9476195
    Abstract: Anchoring system is appropriate for solid rock and concrete (2) and any firm bearing system. The anchor rod (4) of for example a threaded bar out of a shape memory alloy (SMA) is held in the armature bore (3) with a filling compound (5) as anchoring means. For filling the achoring bore (3) between anchor rod (4) and wall of the armature bore (3) a heat resistant filling compound (5) of a polymer connection on a two-component-basis or such on a cementous basis is used. Then the anchor rod (4) is heated by heat input over its butt that is emerging the filling compound on its austenit phase, which pre tensions the anchor rod (4). Finally, after the cooling of the filling compound (5) the anchor rod (4) is cooling of to ambient temperature. A counter bearing board (10) lays on the outer wall (1) around the port of the armature bore (3) and is tensed up with the anchor rod (4).

  • Patent number: 7708500
    Abstract: The resin anchor comprises an apertured tubular envelope designed to be compressed by a traction element, characterized in that it includes, on the inside of the envelope, a resin component and a hardener component that are intended to be mixed together and to cure under the action of the compression of the envelope, in order to fasten the anchor. The traction element is a stud having a threaded rod part that cooperates with a tapped traction element firmly attached to the end of the bushing. The anchor is fastened both mechanically and chemically, for either solid material or hollow material.

    Abstract: A resin insertion device includes a barrel, a piston within the barrel, and a triggering mechanism. The triggering mechanism includes an air outlet, an air inlet, a venturi tube and at least one trigger piston. A resin insertion device includes a barrel having a collar disposed at a first end and a piston disposed slidably within the barrel. A triggering mechanism is disposed at a second end. A first position of the trigger prevents airflow through an air inlet, a second position allows air through the inlet and an outlet, and a third position prevents airflow through the outlet. A method of inserting resin into a bore hole includes providing an insertion device including a barrel, and a triggering mechanism. The method includes depressing a trigger from a first to a second position, placing at least one resin cartridge within the barrel, and further depressing the trigger.

  • Patent number: 7566189
    Abstract: A resin bonded mine roof bolt having an elongated rod with a first end, a second end, and a resin control surface positioned on the rod between the rod first and second ends. The resin control surface has a channel extending along the length of the bolt for distributing resin and interrupted spiral threads for mixing resin. When installed in a mine roof bore hole with curable resin, the resin control surface mixes the resin and partially fills the bore hole to minimize the amount of resin needed to anchor the bolt.

  • Publication number: 20080219775
    Abstract: A bolt assembly for insertion into a rock wall including a hole having a diameter an a method thereof are provided. The assembly includes a resilient cylinder for insertion into the hole, a shaft for insertion into the cylinder, a grouting material for retaining the shaft within the cylinder and stiffening the assembly, and coupling means for coupling the extremity of the cylinder to the extremity of the shaft. The cylinder has a diameter which is greater than the diameter of the hole when the cylinder is uncompressed. In this manner, the cylinder is radially compressed when inserted into the hole and thereby frictionally engages the hole. The cylinder has an extremity extending outside the hole when it is inserted therein. The shaft includes an extremity which extends outside the hole when the shaft is inserted into the cylinder in an operating position.

  • Patent number: 7374370
    Abstract: A rock bolt anchor includes a top portion permanently fixed to a bottom portion. The top portion carries a package of resin. A spring-loaded mechanism pressurizes the package and forces the resin out when the package is lanced. The bottom portion main body carries a pair of opposed outer shells in a dovetail joint on opposed tapers. The annulus adjacent to the rock bolt anchor is sealed by top and bottom bulkheads. The bottom portion is threaded onto a rock bolt. A hollow and ported lance is threaded onto the exposed end of the rock bolt. The combination is inserted into a drilled hole and the rock bolt rotated. The lance rises and pierces the package releasing into the sealed annulus. Continued rotation of the rock bolt, forces the main body down and the outer shells up the tapers compressing them against the wall of the drilled hole.
