Description

Anclaje mixto, para el amarre de sistemas de protección y estabilización de taludes.Mixed anchor, for mooring systems Slope protection and stabilization.

Objeto de la invenciónObject of the invention

La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un anclaje mixto, diseñado preferentemente para el amarre de sistemas de protección y estabilización de taludes.The present invention, as expressed in the set forth in this specification, refers to an anchor mixed, preferably designed for mooring systems Slope protection and stabilization.

Antecedentes de la invenciónBackground of the invention

Se conocen actualmente diversos tipos de anclajes para sistemas de protección ante la caída de rocas, siendo los más conocidos los que simplemente realizan la fijación de los cables de las pantallas de protección en unas cimentaciones realizadas sobre el terreno o en el propio terreno, U 9401490.Various types of anchors are currently known for protection systems against falling rocks, being the most known those who simply perform the fixing of the cables protection screens in foundations made on the land or on the land itself, U 9401490.

Otros sistemas son las conocidas anclas para roca en las que un extremo se ancla en la roca o en el terreno, en una perforación realizada previamente, y el otro extremo con forma de bucle sobresale para que se le puedan enganchar redes de cable o cables de reparto. Es el caso de la Patente ES 2 076 834, realizada únicamente con cable helicoidal, presentando el mismo determinadas características anticorrosivas.Other systems are the well-known rock anchors in which one end is anchored in the rock or in the ground, in a drilling done previously, and the other end shaped loop protrudes so that you can hook cable networks or distribution cables This is the case of Patent ES 2 076 834, made only with helical cable, presenting the same determined anti-corrosive characteristics

Los anclajes para roca de este tipo tienen el problema de no garantizar un buen amarre a la roca, pues una vez entrado en carga el cable se deforma longitudinalmente, por lo que se disminuye la sección transversal en contacto con el material adherente a la roca, por alargamiento del material y reacomodo de los alambres, lo que origina una pérdida de adherencia y, en consecuencia, una disminución de la resistencia del sistema. Para mantener las condiciones necesarias de seguridad se deberán reemplazar estos cables, debiéndose practicar una nueva perforación donde instalar otro cable, suponiendo los sucesivos cambios de material un gasto considerable de mano de obra.Rock anchors of this type have the problem of not guaranteeing a good mooring to the rock, because once when the cable is loaded, the cable deforms longitudinally, so the cross section in contact with the material is decreased adherent to the rock, due to elongation of the material and rearrangement of the wires, which causes a loss of adhesion and, in Consequently, a decrease in system resistance. For maintain the necessary safety conditions must be replace these cables, having to practice a new drilling where to install another cable, assuming the successive changes of material a considerable expense of labor.

Descripción de la invenciónDescription of the invention

La invención resuelve plenamente los problemas expuestos mediante un anclaje con armadura rígida consistente en una barra de acero roscable que se fija al terreno, y una cabeza de cable en forma de gaza sujeta a la armadura por medio de un manguito roscado sobre la barra.The invention fully solves the problems exposed by an anchor with rigid reinforcement consisting of a threaded steel bar that is fixed to the ground, and a head of gauze-shaped cable attached to the armor by means of a threaded sleeve on the bar.

Las principales características son una rigidez de la armadura que garantiza la adherencia con el terreno, debiendo cambiarse únicamente la cabeza del anclaje cuando se ha producido una sobrecarga o un deterioro en el cable, realizándose este cambio de manera sencilla en un desenroscado del manguito.The main features are a stiffness of the armor that guarantees the adhesion with the ground, owing only change the anchor head when it has occurred an overload or deterioration in the cable, making this change easily in a unscrewed sleeve.

Este anclaje ha de garantizar la transmisión de los esfuerzos recibidos en la cabeza a la parte estable del terreno, sin pérdida de resistencia o flexión de la armadura una vez que ésta se va cargando.This anchor must guarantee the transmission of the efforts received in the head to the stable part of the terrain, without loss of resistance or bending of the armor a Once it is charging.

Con el fin de poder describir con el máximo detalle las características esenciales del soporte a que se hace referencia, se adjuntan a esta descripción unos dibujos en los que, a modo de ejemplo no limitativo, se ha representado una realización práctica del mencionado anclaje mixto.In order to be able to describe with the maximum detail the essential characteristics of the support to which it is made reference, are attached to this description some drawings in which, by way of non-limiting example, an embodiment has been represented practice of the mentioned mixed anchor.

Descripción de una forma de realización preferidaDescription of a preferred embodiment

La invención está formada por dos partes diferenciadas, la armadura del anclaje y la cabeza del anclaje. La primera está constituida por una barra de acero macizo con rosca exterior (1), de diámetro y longitud variable, que se introduce en una perforación previamente realizada en el terreno, cuyo diámetro ha de ser superior al de la armadura, inyectándose posteriormente una lechada de cemento o una resina para asegurar la fijación y la adherencia de la armadura con el terreno. La cabeza del anclaje está formada por un cable que se cierra sobre sí mismo (2), formando una gaza, el cual se une a la armadura por medio de un manguito (3).The invention is formed by two parts differentiated, the anchor armor and the anchor head. The The first consists of a solid steel bar with thread exterior (1), of diameter and variable length, which is introduced in a drilling previously done in the field, whose diameter must be superior to that of the armor, then injected a cement grout or resin to ensure fixation and adhesion of the armor with the ground. Anchor head It is formed by a cable that closes on itself (2), forming a gaza, which joins the armor by means of a sleeve (3).

El manguito presenta un tope roscado en el interior de su extremo de mayor sección (4), conteniendo en su parte media dos perforaciones con un diámetro que permita la entrada de los extremos del cable que forma la gaza (Fig. 3). Se dispondrán sobre los extremos de dicho cable, una vez introducidos en el manguito, anillos de aluminio prensado (5) que impedirán la salida de los cables. Para garantizar que la unión de la gaza con el manguito sea resistente se inyectará posteriormente una resina (6), rellanándose el espacio existente entre el tope y la superficie con rosca interior de la parte estrecha del manguito.The sleeve has a threaded stop on the inside of its end of greater section (4), containing in its middle part two perforations with a diameter that allows the entrance of the ends of the cable that forms the gauze (Fig. 3). Be will have on the ends of said cable, once introduced in the sleeve, pressed aluminum rings (5) that will prevent cable outlet. To ensure that the union of the gaza with the cuff is resistant, a resin will be subsequently injected (6), filling the space between the stop and the internal threaded surface of the narrow part of the sleeve.

La parte estrecha del manguito se enroscará en el extremo superior de la barra que conforma la armadura del anclaje, disponiéndose una superficie de roscado interior a lo largo de esta zona (Fig. 4).The narrow part of the cuff will curl into the upper end of the bar that forms the anchor reinforcement, an internal threading surface being arranged along this zone (Fig. 4).

En el modo de realización la barra se introducirá en el terreno dejando fuera una parte equivalente a la superficie de roscado del manguito sobre la barra, permitiendo de este modo el fácil cambio de la cabeza del anclaje.In the embodiment, the bar will be introduced on the ground leaving out a part equivalent to the surface of threaded the sleeve on the bar, thus allowing the Easy change of anchor head.

La invención se empleará en la instalación de los cables dispuestos atirantados entre la cabeza de anclaje y los postes de la empalizada o la pantalla de seguridad.The invention will be used in the installation of cables arranged cabled between the anchoring head and the palisade posts or safety screen.

El cable de la cabeza del anclaje será protegido contra la corrosión por un polímero estable frente a los rayos uva.The anchor head cable will be protected against corrosion by a stable polymer against lightning grape.

Para que las cargas que se transmiten a la cabeza del anclaje, por medio de una red de cable u otro cable, no se concentren en un solo punto del cable, produciendo el cierre de la gaza y, en consecuencia, la disminución de la resistencia del cable que se produciría por la aplicación de un esfuerzo cortante puntual, se colocará forrando parte del cable un guarda-cabos, que mantendrá un radio de curvatura mínimo en el cable (7).So that the loads that are transmitted to the head of the anchor, by means of a cable network or other cable, is not concentrate on a single point of the cable, causing the closure of the gaza and, consequently, the decrease in cable resistance that would be produced by the application of a shear effort punctual, it will be placed covering part of the cable a bodyguard, which will maintain a radius of curvature minimum in the cable (7).

Debe entenderse que la invención ha sido descrita según la realización preferida de la misma, por lo que puede ser susceptible de modificaciones de forma, tamaño y materiales, siempre y cuando dichas alteraciones no varíen sustancialmente las características del invento que se reivindican a continuación.It should be understood that the invention has been described. according to the preferred embodiment thereof, so it can be susceptible to changes in shape, size and materials, as long as these alterations do not vary substantially characteristics of the invention that are claimed below.
