Abstract

La invención proporciona un conjunto de expansión para un perno para roca que incluye: un ancla de expansión que se extiende entre un extremo distal y un extremo proximal, comprendiendo el ancla; una formación de unión; y una pluralidad de aletas de expansión, teniendo cada aleta un cuerpo con una superficie exterior cilíndrica formada con una pluralidad de dientes serrados que se extienden de manera circunferencial alrededor de la superficie exterior, y una superficie interior de sección decreciente lisa que, cuando las aletas se mantienen juntas por la formación de unión, proporcionan un paso de sección decreciente que es de sección decreciente hacia dentro desde el extremo distal hasta el extremo proximal; y un taco de sección decreciente que puede acoplarse a un perno para roca y que se dispone para pasar al interior del paso de sección decreciente desde el extremo proximal para separar las aletas; en el que cada diente serrado está definido por una superficie cónica y una superficie rebajada que se extiende de manera lateral con relación al eje del paso; y en el que la pluralidad de dientes serrados incluye una primera serie de dientes serrados que comienzan de manera adyacente al extremo distal, teniendo cada diente serrado de esta serie una superficie rebajada con una anchura en un primer intervalo; y una segunda serie de dientes serrados, teniendo cada diente serrado de esta serie una superficie rebajada que es más ancha progresivamente que el diente serrado anterior de la segunda serie, esta serie avanza hacia el extremo proximal, con una anchura en un segundo intervalo.The invention provides an expansion assembly for a rock bolt including: an expansion anchor extending between a distal end and a proximal end, the anchor comprising; a bonding formation; and a plurality of expansion fins, each fin having a body with a cylindrical outer surface formed with a plurality of serrated teeth extending circumferentially around the outer surface, and a smooth tapered inner surface which, when the fins held together by the bond formation, provide a tapered pitch that is tapered inward from the distal end to the proximal end; and a tapered plug that can be coupled to a rock bolt and is arranged to pass into the tapered passageway from the proximal end to separate the fins; wherein each serrated tooth is defined by a conical surface and a recessed surface that extends laterally relative to the axis of the pitch; and wherein the plurality of serrated teeth includes a first series of serrated teeth beginning adjacent the distal end, each serrated tooth in this series having a recessed surface with a width in a first interval; and a second series of serrated teeth, each serrated tooth of this series having a recessed surface that is progressively wider than the anterior serrated tooth of the second series, this series advancing towards the proximal end, with a width in a second interval.
