An anchoring adhesive includes effective amounts of an isocyanurate compound and a vinyl ester compound that react and cure to form a composition having high compressive strength, high tensile strength and low shrinkage. The anchoring adhesive can be used to firmly bond anchor pins to boreholes in concrete, steel, wood, and other substrates.

Isocyanurate vinyl ester anchoring adhesive composition

A chemical anchoring assembly useful for fast application of a driving tool into a borehole includes an elongated tube having a first end and a second end, a quantity of chemical anchoring material within the elongated tube, and a vent at the second end of the elongated tube. As an anchor pin is driven through the elongated tube and into the borehole, forcing the chemical anchoring material into the borehole, some of the pressure caused by compression of the chemical anchoring material is released into the vent, allowing easier driving of the anchor pin.

An anchoring adhesive combination includes a slug or package of chemical anchoring adhesive having a proximal end and a distal end and a rod which can be a penetrator having a pointed proximal end, and open distal end, and a threaded or corrugated outer surface. The pointed proximal end of the penetrator is connected to the distal end of the slug or package of chemical anchoring adhesive so that the pointed proximal end is at least partially surrounded by chemical anchoring adhesive. The open distal end of the penetrator receives a proximal end of an anchor pin to form a combination of anchor pin, penetrator and slug or package of anchoring adhesive in series. By placing the combination adjacent to a borehole and simply pounding a distal end of the anchor pin an integrated method is performed whereby a) anchoring adhesive is released and mixed in the borehole, b) the inner wall of the borehole is scrubbed and scored by the outer surface of the penetrator, and c) the anchor pin is both mechanically anchored in the borehole using the penetrator and chemically anchored using the mixed chemical anchoring adhesive.
