Viga prefabricada para pasarela. Prefabricated catwalk beam.
La presente memoria descriptiva se refiere, como su título indica, a una viga prefabricada para pasarela, del tipo de las utilizadas principalmente para la realización de pasarelas peatonales, caracterizada por una sección transversal en forma de “T” invertida, conformando un piso plano del que emerge verticalmente en su parte central un nervio que, longitudinalmente, adopta la forma de un arco que soporta el piso. The present specification refers, as its title indicates, to a prefabricated walkway beam, of the type used primarily for the realization of pedestrian walkways, characterized by an inverted "T" shaped cross-section, forming a flat floor of the that a nerve emerges vertically in its central part that, longitudinally, takes the form of an arch that supports the floor.
En la actualidad son ampliamente conocidos múltiples y variados tipos de formas de construcción de pasarelas para peatones, que permiten salvar vanos o efectuar cruces elevados. Es muy frecuente la utilización de elementos o módulos prefabricados de hormigón para facilitar y abaratar la construcción, tal y como podemos encontrar reivindicado en el Modelo de Utilidad 178801 “Viga para formación de pasarelas”, que presenta la construcción mediante unas vigas que conforman los laterales del piso, entre los cuales se dispone el piso, separado en varias partes de menor longitud que las laterales. Esta construcción tiene el inconveniente de utilizar gran número de piezas y de no poder soportar grandes longitudes de pasarela. Nowadays, multiple and varied types of ways of building walkways for pedestrians are widely known, which allow saving spans or crossings. The use of prefabricated concrete elements or modules to facilitate and reduce the construction is very frequent, as we can find claimed in Utility Model 178801 “Beam for the formation of walkways”, which presents the construction by means of beams that make up the sides of the floor, among which the floor is arranged, separated into several parts of shorter length than the sides. This construction has the disadvantage of using a large number of parts and of not being able to withstand large lengths of catwalk.
Otro ejemplo de elemento prefabricado lo encontramos en la Patente Europea 96902397 “Viga de enrejado, principalmente para formar una barandilla portadora de pasarela suspendida” pero presenta el inconveniente de que el elemento prefabricado soluciona únicamente la barandilla de la pasarela, no el piso. Another example of a prefabricated element is found in European Patent 96902397 "Lattice beam, mainly to form a suspended railing carrier railing" but it has the disadvantage that the prefabricated element solves only the railing of the gangway, not the floor.
Asimismo se encuentra alguna referencia como por ejemplo el Modelo de Utilidad 262634 “Viga de hormigón armado y pretensado” que consiste en una variación de una viga convencional, con alma hueca cerrada con sección de contorno trapezoidal isósceles invertido, con unas alas coplanarias que definen en su parte superior el piso plano de la pasarela, pero presenta del problema de la gran altura de transporte que necesita, además del Inconveniente añadido del escalón de acceso que hay que salvar para los peatones mediante rampas o construcciones auxiliares. There is also some reference, such as Utility Model 262634 “Reinforced and prestressed concrete beam” which consists of a variation of a conventional beam, with a closed hollow core with an inverted isosceles trapezoidal contour section, with coplanar wings defined in its upper part is the flat floor of the walkway, but it presents the problem of the high transport height it needs, in addition to the added inconvenience of the access step to be saved for pedestrians by means of ramps or auxiliary constructions.
Son asimismo conocidas las pasarelas realizadas como un puente pequeño, con un piso construido sobre unas vigas prefabricadas, rematado con unas barandillas laterales, pero presenta el inconveniente de necesitar varios elementos estructurales diferentes, además de crear también un importante escalón de acceso. The walkways made as a small bridge are also known, with a floor built on prefabricated beams, topped with side rails, but it has the disadvantage of needing several different structural elements, as well as creating an important access step.
Para solventar la problemática existente en la actualidad en cuanto a la construcción de pasarelas para peatones se ha ideado la viga prefabricada para pasarela objeto de la presente invención, la cual tiene una sección transversal en forma de “T” invertida, conformando un piso plano del que emerge verticalmente en su parte central un nervio que, longitudinalmente, adopta la forma de un arco que soporta el piso. To solve the current problem regarding the construction of walkways for pedestrians, the prefabricated beam for the walkway object of the present invention has been devised, which has an inverted “T” shaped cross-section, forming a flat floor of the that a nerve emerges vertically in its central part that, longitudinally, takes the form of an arch that supports the floor.
El nervio central puede ser macizo o bien estar aligerado mediante un hueco interior. The central nerve can be solid or lightened by an internal hollow.
Sobre los laterales del piso plano se instalan las barandillas laterales, de cualquiera de los tipos convencionalmente conocidos y utilizados. On the sides of the flat floor side rails are installed, of any of the conventionally known and used types.
Esta viga permite realizar pasarelas sencillas, con un único vano, empleando una sola viga apoyada en sus extremos en sendos soportes o pilas. This beam allows simple gateways to be made, with a single span, using a single beam resting on its ends on two supports or batteries.
vigas utilizando pilas intermedias en las que se apoyan las vigas, que son unidas entre sí por la armadura utilizando técnicas convencionales de unión de elementos prefabricados. beams using intermediate piles on which the beams are supported, which are joined together by the armor using conventional techniques of joining prefabricated elements.
Esta viga prefabricada para pasarela que se presenta aporta múltiples ventajas sobre los elementos disponibles en la actualidad siendo la más importante que integra el piso y un arco de soporte en una única viga prefabricada, con el consiguiente ahorro de elementos. This prefabricated catwalk beam that is presented provides multiple advantages over the elements currently available, being the most important that integrates the floor and a support arch in a single prefabricated beam, with the consequent saving of elements.
Es asimismo destacable que esta viga permite construir pasarelas sin apenas escalón de acceso, evitando la necesidad de escaleras o rampas de acceso, con el consiguiente ahorro económico. It is also noteworthy that this beam allows you to build walkways with hardly any access step, avoiding the need for stairs or access ramps, with the consequent economic savings.
Asimismo debemos resaltar que esta viga es fácilmente transportable e instalable, con el consiguiente ahorro de tiempo de instalación. We must also emphasize that this beam is easily transportable and installable, with the consequent saving of installation time.
Destacar asimismo, que la viga permite la realización mediante una única viga prefabricada de pasarelas de hasta 40 ó 50 metros de longitud. Also note that the beam allows the realization by means of a single prefabricated beam of walkways up to 40 or 50 meters in length.
Por último resaltar que, en caso necesario, las vigas pueden unirse entre sí y, mediante el apoyo en pilas o soportes, salvar vanos de cualquier longitud de una manera sencilla y económica. Finally, it should be noted that, if necessary, the beams can be joined together and, by means of support in batteries or supports, save spans of any length in a simple and economical way.
