<p>A pull-up bolting assembly is constructed to be inserted endwise and rotatably advanced as a unit within a bore hole of a rock-like roof or other structure, with the forward end of the assembly being employed to fracture an in-placed, adhesive resin material containing capsule, and to mix the adhesive material and force it about a hollow pipelike anchor member of the assembly and along the spacing between it and the bore hole. After the adhesive material has set or hardened about the hollow anchor member to non-rotatably fix it in position within a back end portion of the bore hole, a stop means is sheared by a bolt member of the assembly which is then relatively rotatably advanced within a resin-clear, front portion of the bore hole into and along the hollow anchor member until a bearing plate of the assembly is tension-held by the bolt against an outer face of the rock-like structure.</p> |
