Estructura auxiliar de absorcion de energfaAuxiliary energy absorption structure

[0001] La invencion se refiere a una estructura auxiliar de absorcion de energfa con construccion flexible de proteccion para edificios construcciones flexibles de proteccion contra impactos por piedras, impactos por cafdas de arboles, aludes o similares.[0001] The invention relates to an auxiliary structure for energy absorption with flexible construction protection for buildings, flexible constructions for protection against impacts from stones, impacts from tree coffees, avalanches or the like.

[0002] Se conoce una construccion de proteccion a partir del documento US-A-5.299.781. A partir del documento DE 20 3 0 0 821 U se conoce otra construccion de proteccion contra impactos por piedras, impactos por cafdas de arboles, aludes o similares, que comprende una estructura auxiliar de absorcion de energfa, una estructura de retencion, unos soportes, que por medio de una estructura de union se conectan con la estructura de retencion, y elementos de absorcion de energfa.[0002] A protection construct is known from US-A-5,299,781. From document DE 20 3 0 0 821 U another construction of protection against impacts by stones, impacts from tree coffees, avalanches or the like is known, comprising an auxiliary energy absorption structure, a retention structure, supports, that through a union structure are connected to the retention structure, and energy absorption elements.

Los elementos de absorcion de energfa soportan asf la estructura de elementos de union en la region de su fijacion en el subsuelo, fijando la estructura de elementos de union en el subsuelo mediante un anclaje de roca o similares mediante los elementos de absorcion de energfa.The energy absorption elements thus support the structure of union elements in the region of their fixation in the subsoil, fixing the structure of union elements in the subsoil by means of a rock anchor or the like by means of the energy absorption elements.

[0003] Es el objetivo tecnico de la presente invencion conseguir una reduccion de energfa eficaz de las construcciones de proteccion contra impactos por piedras, impactos por cafdas de arboles, aludes o similares, donde debe ser posible conseguir deformaciones globales inferiores del sistema y un dimensionado mas reducido de elementos de la estructura de retencion, de union y de apoyo, asf como su anclaje al subsuelo.[0003] It is the technical objective of the present invention to achieve an effective energy reduction of the constructions of protection against impacts by stones, impacts by coffee trees, avalanches or the like, where it should be possible to achieve lower overall deformations of the system and a dimensioning smaller elements of the structure of retention, union and support, as well as its anchorage to the subsoil.

[0004] La resolucion de este objetivo se realiza por las caracterfsticas de la reivindicacion 1.[0004] The resolution of this objective is carried out by the characteristics of claim 1.

[0005] De este modo se consigue, entre otras cosas, que la estructura de retencion, despues del montaje de la estructura de apoyo, se pueda correr y descorrer a modo de cortina, lo que simplifica considerablemente el montaje de la disposicion global.[0005] In this way, it is achieved, among other things, that the retention structure, after the assembly of the support structure, can be run and uncorked as a curtain, which considerably simplifies the assembly of the overall arrangement.

[0006] La invencion se refiere a una construccion flexible de proteccion contra impactos por piedras, impactos por cafdas de arboles, aludes o similares, que se integra directamente en la estructura de retencion, de manera que una gran parte de la entrada de energfa, introducida por un cuerpo de piedra cayente, rodante o que bota o similares ya se puede reducir mediante la combinacion de la estructura de retencion y la estructura de soporte de absorcion de energfa.[0006] The invention relates to a flexible construction of protection against impacts from stones, impacts from tree coffees, avalanches or the like, which is integrated directly into the retention structure, so that a large part of the energy input, introduced by a falling, rolling or bouncing stone body or the like can already be reduced by combining the retention structure and the energy absorption support structure.

[0007] La invencion preve preferiblemente que se integren con esta finalidad elementos de union como, por ejemplo, cables de acero o similares, a traves de toda la longitud de construccion de la construccion de proteccion, con determinadas separaciones de los cables de soporte (cables de borde), aproximadamente de forma paralela a los mismos, en la estructura de retencion. Con esta finalidad se une la estructura de los elementos de union directamente con la estructura de retencion usada (por ejemplo: red de anillo, red de omega o similares) y/o con su soporte de enrejado. Esta union se puede producir a traves de elementos de union convencionales como, por ejemplo, elementos de inmovilizacion, grilletes o similares, o la estructura de los elementos de union se puede coser o enlazar con la estructura de retencion (por ejemplo: redes de anillo, redes de omega o similares) y/o su asiento de enrejado. En el caso de la conduccion de los elementos de union a traves de los elementos de la estructura de apoyo no se realiza la union de la estructura de soporte de absorcion de energfa en la region de la estructura de retencion con la estructura de apoyo, para que no se perjudique a la libertad de movimiento de la estructura de retencion.[0007] The invention preferably provides that joining elements such as steel cables or the like are integrated for this purpose, throughout the entire construction length of the protective construction, with certain separations of the support cables ( edge cables), approximately parallel to them, in the retention structure. For this purpose, the structure of the joining elements is directly linked with the retention structure used (for example: ring net, omega net or the like) and / or with its trellis support. This union can be produced through conventional joining elements such as immobilization elements, shackles or the like, or the structure of the joining elements can be sewn or linked to the retention structure (for example: ring networks , omega nets or the like) and / or its trellis seat. In the case of the conduction of the connecting elements through the elements of the support structure, the union of the energy absorption support structure in the region of the retention structure with the support structure is not carried out, for that does not harm the freedom of movement of the retention structure.

[0008] El numero de los elementos de union usados, denominados a continuacion cuerdas centrales, y su separacion de las cuerdas de soporte se tiene que adaptar a la construccion de proteccion usada o su clase de absorcion de energfa.[0008] The number of the union elements used, referred to below as central ropes, and their separation from the support ropes must be adapted to the construction of protection used or its energy absorption class.

[0009] La invencion se distingue particularmente por las siguientes ventajas:[0009] The invention is particularly distinguished by the following advantages:

1) Por la combinacion de la estructura de soporte de absorcion de energfa con la estructura de retencion y/o su soporte de enrejado a traves de la longitud de construccion) y un numero seleccionado adecuadamente (para la entrada de energfa esperada) de cuerdas centrales y separaciones seleccionadas correspondientemente entre las cuerdas centrales instaladas y las cuerdas de soporte, la estructura de retencion de la construccion de proteccion esta apoyada uniformemente (de forma simetrica) a traves por toda su superficie mediante la estructura auxiliar de absorcion de energfa.1) By the combination of the energy absorption support structure with the retention structure and / or its trellis support through the construction length) and a properly selected number (for the expected energy input) of central ropes and separations correspondingly selected between the installed central ropes and the support ropes, the retention structure of the protection construction is supported uniformly (symmetrically) through its entire surface by means of the auxiliary energy absorption structure.

2) Ya que en la zona de impacto de un cuerpo de piedra o similares en la construccion de proteccion se produce la mayor deformacion del sistema (debido a la elasticidad de la estructura de retencion usada), las cuerdas centrales, que cubren esta zona, se cargan inmediatamente con fuerzas de traccion y pueden pasar las mismas inmediatamente a los elementos de absorcion de energfa unidos. De este2) Since in the area of impact of a stone body or the like in the construction of protection the greatest deformation of the system occurs (due to the elasticity of the retention structure used), the central cords, which cover this area, they are loaded immediately with tensile forces and can be passed immediately to the joined energy absorption elements.

modo, por una rapida reduccion de energfa se alivian considerablemente todos los componentes del sistema (sobre todo la estructura de union).Thus, by a rapid reduction of energy, all the components of the system are relieved considerably (especially the joint structure).

3) En el caso de deformaciones del sistema de los que se espera que seran muy intensas (hasta 6 m), se pueden utilizar elementos de absorcion de energfa, que ya se activan con una actuacion de fuerza reducida que, en cambio, permiten deformaciones intensas, o se pueden cambiar en serie a los elementos de absorcion de energfa que se usan en la actualidad. De este modo, se puede reducir energfa a traves de un recorrido mas largo, sin que por esto se vea influenciado negativamente el funcionamiento del sistema global (por ejemplo: mantenimiento de una cierta altura util restante despues de un impacto).3) In the case of deformations of the system that are expected to be very intense (up to 6 m), energy absorption elements can be used, which are already activated with a reduced force action that, on the other hand, allow deformations intense, or can be changed in series to the energy absorbing elements that are currently used. In this way, energy can be reduced over a longer route, without this negatively influencing the operation of the global system (for example: maintaining a certain remaining useful height after an impact).

4) Al contrario, mediante el alivio de la estructura de union (cuerdas de soporte y cuerdas de retencion), al que en la mayorfa de los casos le ayuda la instalacion de elementos de absorcion de energfa, se mejora considerablemente la consecucion de una altura util restante predefinida.4) On the contrary, by relieving the joint structure (support ropes and retention ropes), which in most cases helps the installation of energy absorbing elements, the attainment of a height is greatly improved remaining utility predefined.

5) Debido a la actuacion de frenado inmediata y la aportacion de rigidez a la estructura de retencion mediante la combinacion de la estructura de soporte de absorcion de energfa con la estructura de retencion, se consigue una disminucion considerable de la deformacion global del sistema, es decir, el cuerpo de piedra cayente o similares se puede parar de un modo mas corto. Por consiguiente, los sistemas de construccion se pueden construir mas cerca de los objetos que se tienen que proteger.5) Due to the immediate braking action and the contribution of stiffness to the retention structure by combining the energy absorption support structure with the retention structure, a considerable decrease in the overall deformation of the system is achieved, it is that is, the falling stone body or the like can be stopped in a shorter way. Therefore, construction systems can be built closer to the objects to be protected.

[0010] Las reivindicaciones dependientes contienen mas perfeccionamientos ventajosos de la invencion.[0010] The dependent claims contain more advantageous improvements of the invention.

[0011] Se obtienen otros detalles, caracterfsticas y ventajas de la invencion a partir de la siguiente descripcion de ejemplos de realizacion por medio del dibujo. Se muestra:[0011] Other details, characteristics and advantages of the invention are obtained from the following description of embodiments by means of the drawing. It shows:

En la Figura 1, una vista lateral de una primera realizacion de la estructura de absorcion de energfa de acuerdo con la invencion, yIn Figure 1, a side view of a first embodiment of the energy absorption structure according to the invention, and

En la Figura 2, una vista delantera esquematicamente muy simplificada de una segunda realizacion de la estructura de absorcion de energfa de acuerdo con la invencion.In Figure 2, a schematically simplified front view of a second embodiment of the energy absorption structure according to the invention.

[0012] La Figura 1 muestra la vista lateral de una primera realizacion de una construccion de proteccion contra impactos por piedras, impactos por cafdas de arboles, aludes o similares. La construccion de proteccion presenta una estructura de retencion 1, que se representa esquematicamente por una lfnea con puntos y rayas. En el caso del ejemplo se une por una cuerda de soporte superior 2 y una cuerda de soporte inferior 3 con los elementos de una estructura de apoyo 10.[0012] Figure 1 shows the side view of a first embodiment of a construction of protection against impacts by stones, impacts by tree coffees, avalanches or the like. The protection construction has a retention structure 1, which is schematically represented by a line with dots and stripes. In the case of the example, it is joined by an upper support rope 2 and a lower support rope 3 with the elements of a support structure 10.

[0013] Habitualmente este montaje parecido a un modulo de tales sistemas de proteccion se une a una estructura de retencion, una estructura de union, una estructura de apoyo, su anclaje y, cuando sea necesario, una cimentacion.[0013] Usually this assembly resembling a module of such protection systems joins a retention structure, a joint structure, a support structure, its anchoring and, when necessary, a foundation.

[0014] La estructura de retencion 1 presenta preferiblemente elementos de red de anillos gruesa 1 (por ejemplo: red de anillo, red de omega etc.), a los que les ayuda parcialmente la aplicacion de soportes de enrejado de anillos pequenos, para evitar una penetracion de cuerpos de impacto mas pequenos. El objetivo de la estructura de retencion 1 consiste, como ya indica el nombre, en la retencion de los cuerpos de impacto. Por una deformacion plastica de los elementos de red se reduce una parte de la energfa cinetica introducida por el cuerpo de impacto.[0014] The retention structure 1 preferably has thick ring network elements 1 (for example: ring network, omega net etc.), which is partially helped by the application of small ring trellis supports, to avoid a penetration of smaller impact bodies. The objective of the retention structure 1 consists, as the name already indicates, in the retention of the impact bodies. A part of the kinetic energy introduced by the impact body is reduced by a plastic deformation of the network elements.

[0015] La estructura de retencion 1 se une mediante una estructura de union con la estructura de apoyo. La estructura de union presenta un cuerda de soporte superior o varias cuerdas de soporte superiores 2 y una cuerda de soporte inferior o varias cuerdas de soporte inferiores 3, que tambien se denominan cuerdas de borde, que se tiran de un cabezal de apoyo a otro cabezal de apoyo (o de un pie de apoyo a otro pie de apoyo) a traves de todas las secciones del sistema. Las cuerdas de soporte 2, 3 se fijan en elementos de la estructura de apoyo o por anclajes de roca 9 en el fondo. Fijan la estructura de apoyo con la estructura de retencion.[0015] The retention structure 1 is joined by a joint structure with the support structure. The joint structure has an upper support rope or several upper support ropes 2 and a lower support rope or several lower support ropes 3, which are also called edge ropes, which are pulled from a support head to another head of support (or from one support foot to another support foot) through all sections of the system. The support ropes 2, 3 are fixed on elements of the support structure or by rock anchors 9 at the bottom. They fix the support structure with the retention structure.

[0016] Otros elementos de la estructura de union son cuerdas de retencion 6 que unen los lados del cabezal de los elementos de la estructura de apoyo (por ejemplo: en una realizacion, como apoyos pendulares) en el lado del monte con el subsuelo mediante un anclaje (por ejemplo: anclaje de roca) 9 y, de este modo, los mantienen en una posicion estaticamente determinada. Si los elementos principales de la estructura de apoyo no estan unidos directamente con anclajes de roca o similares con el fondo (por ejemplo: en el caso de un alojamiento flotante), cuerdas de retencion estan colocados ademas adicionalmente en la zona del pie de los elementos de apoyo.[0016] Other elements of the joint structure are retention ropes 6 that join the sides of the head of the elements of the support structure (for example: in one embodiment, such as pendular supports) on the side of the mount with the subsoil by an anchor (for example: rock anchor) 9 and, thus, keep them in a statically determined position. If the main elements of the support structure are not directly connected with rock anchors or similar to the bottom (for example: in the case of a floating housing), retaining ropes are also additionally placed in the foot area of the elements support.

[0017] A los componentes de la estructura de union (cables de soporte 2,3 y cables portadores 6) les ayudan elementos de absorcion de energfa 8. Por los elementos de absorcion de energfa que se han mencionado se reduce una gran parte de la energfa de introduccion por una deformacion plastica y/o elastica.[0017] The components of the joint structure (support cables 2,3 and carrier cables 6) are assisted by energy absorption elements 8. The energy absorption elements mentioned above reduce a large part of the introductory energy by a plastic and / or elastic deformation.

[0018] La estructura de apoyo presenta soportes 10, su longitud (altura constructiva) y su separacion horizontal (longitudes de compartimento) se determinan por la introduccion de energfa esperada. Generalmente son habituales longitudes de compartimento de aproximadamente 10 m.[0018] The support structure has supports 10, its length (construction height) and its horizontal separation (compartment lengths) are determined by the introduction of expected energy. Generally, compartment lengths of approximately 10 m are common.

[0019] El alojamiento de los soportes 10 se realiza preferiblemente por placas de base 5. La union de los soportes 10 a las placas de base 5 se realiza por una articulacion pendular (apoyo pendular) o se produce como una union fija (soldada, atornillada o similares). La placa de base 5 se une con subsuelo directamente por anclajes de roca o similares o se aloja de forma flotante con cables portadores en el lado del monte. En una realizacion como apoyo pendular se retiene la zona del cabezal del soporte 10 con cables portadores 6 en el lado del monte y, de este modo, se mantiene en una posicion estaticamente determinada.[0019] The housing of the supports 10 is preferably carried out by base plates 5. The union of the supports 10 to the base plates 5 is carried out by a pendulum joint (pendulum support) or is produced as a fixed joint (welded, screwed or similar). The base plate 5 is connected with subsoil directly by rock anchors or the like or housed floatingly with carrier cables on the side of the mount. In an embodiment as a pendular support, the area of the support head 10 is retained with carrier cables 6 on the side of the mount and, thus, is maintained in a statically determined position.

[0020] Como ya se ha mencionado, se reduce una gran parte de la energfa de entrante por elementos de absorcion de energfa 8 de los tipos constructivos y modos de funcionamiento mas diversos. Los elementos de absorcion de energfa 8 se utilizan en un contexto muy relacionado con la estructura de union. Se instalan junto con cables portadores 6, cables de soporte 2,3 y/o su gma en la zona de la estructura de apoyo. Ademas es posible proporcionar elementos de absorcion de energfa, que se unen en puntos sobre una estructura de union (por ejemplo: cables de acero) con la estructura de retencion. De este modo, a la estructura de retencion le apoyan directamente elementos de absorcion de energfa.[0020] As already mentioned, a large part of the incoming energy is reduced by energy absorbing elements 8 of the most diverse construction types and modes of operation. The energy absorption elements 8 are used in a context closely related to the joint structure. They are installed together with carrier cables 6, support cables 2.3 and / or their gma in the area of the support structure. It is also possible to provide energy absorption elements, which are joined at points on a joint structure (for example: steel cables) with the retention structure. In this way, energy retention elements are directly supported by the retention structure.

[0021] Los soportes 10 de la estructura de apoyo se alojan sobre dichas placas de base 5, preferiblemente por un enlace pendular. Las placas de base 5 estan fijadas con anclajes de roca 9 en el subsuelo. Los soportes 10 se atirantan con cables portadores 6 en el cabezal en el lado del monte y, de este modo, se mantienen en su posicion. En los cables de retencion 6 se apoyan, en la zona de su anclaje 9, elementos de absorcion de energfa 8.[0021] The supports 10 of the support structure are housed on said base plates 5, preferably by a pendulum link. The base plates 5 are fixed with rock anchors 9 in the basement. The supports 10 are secured with carrier cables 6 in the head on the side of the mount and, thus, are kept in position. In the retention cables 6, energy absorption elements 8 are supported in the area of their anchorage 9.

[0022] El sistema de construccion representado esta provisto en la realizacion representada de dos cuerdas centrales 7 en diferentes alturas. Estos cables 7 se unen, en el caso representado, con la estructura de retencion 1 a traves de toda su longitud (con excepcion de la zona de los soportes 10). En la zona de los soportes o la estructura de apoyo 10 se conducen cuerdas a por gmas de cable (en este caso, grilletes), se apoyan lateralmente por elementos de absorcion de energfa 8 y se fijan con anclajes de roca 9 en el subsuelo.[0022] The construction system represented is provided in the represented embodiment of two central ropes 7 at different heights. These cables 7 are joined, in the case shown, with the retention structure 1 throughout its entire length (with the exception of the area of the supports 10). In the area of the supports or the support structure 10, ropes are driven by cable ranges (in this case, shackles), supported laterally by energy absorbing elements 8 and fixed with rock anchors 9 in the subsoil.

[0023] En la Figura 2 se representa una segunda realizacion de la construccion de proteccion de acuerdo con la invencion, en la que todas las partes que corresponden con la realizacion de acuerdo con la Figura 1 estan indicadas con las mismas referencias. Por consiguiente, se puede hacer referencia a las explicaciones precedentes.[0023] A second embodiment of the protection construction according to the invention is shown in Figure 2, in which all the parts corresponding to the embodiment according to Figure 1 are indicated with the same references. Therefore, reference may be made to the preceding explanations.

[0024] Sin embargo, en la segunda realizacion representada se proporcionan tres cuerdas centrales 7', 7'', 7'''. Tal como ilustra la Figura 2, los mismos tienen un recorrido preferiblemente paralelo entre sf y, asimismo, paralelo al cable de soporte superior 2 o al cable de soporte inferior 3.[0024] However, in the second embodiment shown, three central strings 7 ', 7' ', 7' '' are provided. As Figure 2 illustrates, they preferably have a parallel path between them and also parallel to the upper support cable 2 or the lower support cable 3.

[0025] Tal como tambien en la realizacion de acuerdo con la Figura 1, esta realizacion hace posible durante el montaje de la disposicion global correr a modo de cortina la estructura de retencion 1 entre los soportes 10, donde, previo a su montaje, la estructura de retencion 1 se puede instalar de forma plegada en uno o varios de los soportes 10.[0025] As also in the embodiment according to Figure 1, this embodiment makes it possible during the assembly of the overall arrangement to run the retention structure 1 between the supports 10 as a curtain, where, prior to its assembly, the retention structure 1 can be installed folded into one or more of the supports 10.
