La invención concierne a un tirante de anclaje para fines de construcción, especialmente para afianzar paredes de roca, con una varilla de anclaje que consiste en un material compuesto polímero, que presenta una rosca en su extremo del lado de la cabeza y que está destinada a recibir una tuerca de presión que puede atornillarse sobre la rosca de la varilla de anclaje y que preferiblemente puede apoyarse contra una placa de presión.The invention concerns an anchor strap for construction purposes, especially to secure walls of rock, with an anchor rod consisting of a material polymer compound, which has a thread at its side end of the head and that is destined to receive a pressure nut which can be screwed onto the thread of the anchor rod and which can preferably rest against a pressure plate.
Una barra roscada de material fibroso es ya conocida, por ejemplo, por el documento EP 0 191 337 A.A threaded rod of fibrous material is already known, for example, from EP 0 191 337 A.
Los tirantes de anclaje de esta clase se utilizan sobre todo para el afianzamiento permanente de zonas inestables del terreno, para el anclaje sistemático con miras a aumentar la resistencia de la construcción y para medidas de afianzamiento en la construcción profunda subterránea y especial. Las barras de anclaje se insertan con este fin en taladros de las paredes de roca a afianzar, se pegan con un mortero de anclaje o resina de anclaje y se arriostran con la placa de presión enchufada por el lado de la cabeza y con una tuerca de presión atornillada sobre la rosca. En los tirantes de anclaje conocidos la varilla de anclaje está constituida principalmente por acero o por fibras de vidrio que se pegan en un procedimiento especial con resina de poliéster o resina epoxídica. La rosca a manera de dientes de sierra se talla en la varilla de anclaje. Se percibe aquí como desventajoso el hecho de que las fibras de vidrio se cortan completamente en los puntos de intersección, con lo que se presenta un debilitamiento no deseado del material.Anchor braces of this class are used especially for the permanent consolidation of unstable areas of the ground, for systematic anchoring with a view to increasing the construction strength and for consolidation measures in Deep underground and special construction. The bars of anchor are inserted for this purpose in rock wall drills to be secured, they are glued with an anchor mortar or anchor resin and bracing with the pressure plate plugged into the side of the head and with a pressure nut screwed on the thread. In the known anchor rods the anchor rod is consisting mainly of steel or glass fibers that are glue in a special procedure with polyester resin or resin epoxy. The thread as a sawtooth is carved in the anchor rod The fact that that the glass fibers are cut completely at the points of intersection, resulting in an unwanted weakening of the material.
Partiendo de esto, la invención se basa en el problema de desarrollar un tirante de anclaje de la clase indicada al principio y un procedimiento para su fabricación con el que se simplifique la fabricación de la varilla de anclaje y, no obstante, se pueda lograr una mayor fuerza de tracción.Starting from this, the invention is based on the problem of developing an anchor brace of the indicated class at the beginning and a procedure for its manufacture with which simplify the fabrication of the anchor rod and, nevertheless, greater traction force can be achieved.

Gracias al empleo del material sintético termoplástico es posible conformar la rosca sin virutas en la varilla de anclaje, preferiblemente bajo la acción de presión y calor. Para garantizar un manejo fiable, el punto de transformación vítrea del material sintético termoplástico empleado es de al menos 100°C y el punto de transición a fluencia es de al menos 160ºC.The solution according to the invention is based above all in the idea that in the case of continuous reinforcing fibers it can also achieve a high tensile force in the area of the bagel. To achieve this it is proposed according to the invention that the polymer composite material present a plurality of fibers of reinforcement that extend over the entire length of the rod anchor, which are embedded in a binder matrix of thermoplastic synthetic material and extending uninterrupted in the thread area. Thanks to the use of synthetic material thermoplastic it is possible to form the thread without chips in the anchor rod, preferably under the action of pressure and hot. To ensure reliable handling, the transformation point Vitreous thermoplastic synthetic material used is at least 100 ° C and the transition point at creep is at least 160 ° C.

After custom cutting of the anchor rod, the thread can be shaped in said rod without chips and without cutting the reinforcing fibers under the action of pressure and preferably heat.
Como alternativa a esto, para la fabricación del tirante de anclaje según la invención se puede impregnar un tubo flexible trenzado inicialmente seco formado por fibras de refuerzo con aglomerante termoplástico líquido y este tubo puede ser endurecido con formación de la varilla de anclaje. La rosca y eventualmente una pluralidad de estrías transversales son conformadas en la varilla de anclaje y en su tubo flexible trenzado convenientemente antes del endurecimiento del aglomerante. Sin embargo, es en principio posible también conformar la rosca y eventualmente una pluralidad de estrías transversales en la varilla de anclaje después del endurecimiento del aglomerante bajo la acción de presión y calor.As an alternative to this, for the manufacture of anchoring rod according to the invention a tube can be impregnated flexible braided initially dry formed by reinforcing fibers with liquid thermoplastic binder and this tube can be hardened with anchor rod formation. The thread and eventually a plurality of cross streaks are formed on the anchor rod and its braided flexible tube conveniently before hardening of the binder. Without However, in principle it is also possible to shape the thread and possibly a plurality of cross streaks on the rod anchor after hardening of the binder under the pressure and heat action.
Para anclar el tirante de anclaje según la invención en un taladro de la roca o de la obra de construcción se puede calentar localmente, según la invención, la varilla de anclaje introducida en el taladro, a través de su cavidad central, hasta más allá del punto de transformación a fluencia de su aglomerante y se puede unir dicha varilla con la pared del taladro mediante un acoplamiento por medio de los propios materiales y/o un acoplamiento positivo de forma. Empleando un aglomerante hinchable, la varilla de anclaje puede ser calentada además localmente con hinchamiento del aglomerante. Para calentar localmente la varilla de anclaje se introduce preferiblemente una lanza de calentamiento en el taladro de la varilla de anclaje y se calienta ésta eléctricamente.To anchor the anchor strap according to the invention in a rock drill or construction site is can heat the rod according to the invention locally anchor introduced into the hole, through its central cavity, until beyond the creep transformation point of its binder and said rod can be attached to the hole wall by coupling through the materials themselves and / or a positive coupling form. Using an inflatable binder, The anchor rod can also be heated locally with binder swelling. To heat the rod locally anchor is preferably introduced a heating lance in the anchor rod drill and it is heated electrically

The anchor rod has a central cavity 22 and is protected at its tip by a hood Detachable 24. It consists of a polymer composite with reinforcing fibers 18 consisting mainly of fibers of carbon (hybrids) and that are embedded in a binder matrix 20 based on thermoplastic synthetic material. Fibers of endless reinforcement 18 is embedded in the binder matrix 20 conveniently by the coextrusion procedure or by the pultrusion procedure and, after hardening, it cut to the desired length of the anchor rod. The thermoplastic binder matrix 20 takes care that the rod of anchor is sufficiently rigid at the temperature of use and can deform plastically by heating at a temperature by above the glass transformation point. Therefore, the thread 12 can be practiced on the prefabricated anchor rod 10 under the action of pressure and eventually heat without cutting the reinforcing fibers 18. There is no weakening Inadmissible material in the thread area. In addition, they can stretch marks are formed under pressure on the anchor rod 10 cross-sections 26 that are arranged at a distance from each other in the entire length and that guarantee a better anchorage in the material injected.
