Description

Prelosa autoportante.Self-supporting prelosa.

La presente memoria descriptiva se refiere, como su título indica, a una prelosa autoportante, ligera, de montaje rápido sobre las vigas prefabricadas del tipo utilizado para la construcción de viaductos, puentes y similares.The present specification refers to, as its title indicates, to a self-supporting, lightweight, mounting pre-slab fast on prefabricated beams of the type used for construction of viaducts, bridges and the like.

En la actualidad son conocidos diferentes tipos de prelosa autoportante, en algunos casos son prelosas convencionales fabricadas in situ para su posterior colocación sobre las vigas de los puentes o viaductos, siendo su construcción y montaje por partes, pues es necesario un tiempo de espera mientras se fragua el hormigonado.At present, different types of self-supporting pre-slab are known, in some cases they are conventional pre-slabs manufactured in situ for their subsequent placement on the beams of the bridges or viaducts, being their construction and assembly by parts, since a waiting time is necessary while Forge the concrete.

Actualmente para la realización de proyectos diseñados para puentes de pequeño tamaño o pasarelas, las prelosas utilizadas, no ofrecen mayores inconvenientes a la hora de transportar los elementos prefabricados que componen el conjunto, pues al ser puentes o pasarelas de pequeño tamaño, las dimensiones de los diferentes elementos y vigas prefabricadas que conforman el conjunto permiten su manipulación y traslado por carretera sin mayores
contratiempos.
At the moment for the realization of projects designed for small bridges or walkways, the pre-slabs used, do not offer major inconveniences when transporting the prefabricated elements that make up the set, since being small bridges or walkways, the dimensions of the different elements and prefabricated beams that make up the assembly allow its handling and transport by road without major
setbacks

Pero cuando se realiza un proyecto de gran envergadura como grandes puentes o viaductos donde además se requiere una determinada luz y que además las vigas alojen la conducción o tuberías de grandes diámetros, se requieren unas vigas de grandes dimensiones, ya que al utilizarse prelosas convencionales el canto útil resulta insificiente para el alojamiento de las conducciones de grandes diámetros.But when a great project is done wingspan like large bridges or viaducts where also requires a certain light and that the beams also house the conduction or large diameter pipes, beams are required of large dimensions, since when using pre-slabs conventional useful singing is insufficient for large diameter conduit housing.

El principal inconveniente que se plantea es el incremento de las dimensiones de las vigas, para aumentar su canto útil y poder alojar las conducciones o tuberías que se requieran, pero nos encontramos con el inconveniente de la reducción de luz del puente además del aumento de peso que debe soportar la estructura, y el problema añadido del transporte, al sobrepasar las medidas reglamentadas para que se puedan transportar por carretera, tanto por dimensiones, como por el peso, teniendo en cuenta que en la mayoría de los casos el acceso a pie de obra no resulta sencillo tanto por la propia carretera en si, como por la orografía del terreno.The main drawback that arises is the increase of the dimensions of the beams, to increase its edge useful and able to accommodate the pipes or pipes that are required, but we find the disadvantage of the reduction of light of the bridge in addition to the weight gain that the structure, and the added problem of transport, by exceeding regulated measures so that they can be transported by road, both by dimensions, and by weight, taking into account that in In most cases, access to the work site is not easy both by the road itself, and by the orography of the ground.

Otro inconveniente que presentan estas vigas de grandes dimensiones, es que para poder realizar el proyecto, ante la imposibilidad de poder transportarlas por carretera, resulta necesario realizar a pie de obra la construcción de estas, con el consiguiente aumento económico que genera el incremento de mano de obra, la inversión en recursos humanos y en bienes de equipo y por consiguiente mayores plazos de tiempo para la realización de la obra.Another drawback presented by these beams large dimensions, is that to be able to carry out the project, before the impossibility of being able to transport them by road is it is necessary to carry out the construction of these, with the consequent economic increase that generates the increase of hand of work, investment in human resources and capital goods and by consequently longer periods of time for the realization of the work.

Finalmente es digno de destacar que debido a la particular estructura de estas vigas de grandes dimensiones, al ser fabricadas a pie de obra, resulta muy costoso y de difícil ejecución realizar el debido control de calidad que se requiere para este tipo de construcciones.Finally it is worth noting that due to the particular structure of these large beams, being manufactured on site, it is very expensive and difficult execution perform the necessary quality control that is required For this type of construction.

Para solventar la problemática existente en la actualidad, se ha ideado una prelosa autoportante objeto de la presente invención, la cual está constituida por un ligero perfil de hormigón, con unos refuerzos transversales que sobresaliendo por su parte inferior, se asientan sobre las vigas, aumentando el canto útil, dotando al puente de grandes luces, pudiendo instalarse conducciones o tuberías de grandes diámetros, sin necesidad de recurrir a modificar las dimensiones de las vigas.To solve the problem in the At present, a self-supporting prelosa object of the present invention, which is constituted by a slight profile of concrete, with transverse reinforcements that protruding from its lower part, settle on the beams, increasing the edge useful, providing the bridge with great lights, and can be installed pipes or pipes of large diameters, without the need for resort to modifying the dimensions of the beams.

La prelosa autoportante objeto de la presente invención, adquiere una forma rectangular y está constituida por un ligero perfil de hormigón siendo la parte central plana y de menor grueso, estando los laterales de ambos lados con una ligera inclinación ascendente, teniendo en ambos extremos una corta prolongación perpendicular, la cual aloja dos refuerzos transversales, ubicados a distancia equidistante.The self-supporting prelosa object of the present invention, acquires a rectangular shape and is constituted by a lightweight concrete profile being the central part flat and smaller thick, being the sides of both sides with a slight ascending inclination, having at both ends a short perpendicular extension, which houses two reinforcements transversal, located at equidistant distance.

Cada refuerzo está dotado con dos salientes que sobresalen por la parte inferior de la prelosa autoportante, y ubicados en los límites de la zona plana de dicha prelosa.Each reinforcement is equipped with two protrusions that protrude from the bottom of the self-supporting pre-slab, and located in the limits of the flat area of said pre-slab.

La zona de la prelosa autoportante donde están ubicados los salientes, se encuentra libre de material, y constituida por unos perfiles que adoptan la inclinación del saliente de los refuerzos.The area of the self-supporting prelosa where they are located the projections, is free of material, and constituted by profiles that adopt the inclination of outgoing reinforcements.

Estas zonas libres de material permiten el paso de los anclajes metálicos con los que están dotados las vigas, para asegurar la compactación y fijación de la prelosa con las vigas en el momento de fraguarse el hormigonado.These material-free zones allow passage of the metal anchors with which the beams are equipped, for ensure compaction and fixation of the pre-slab with the beams in the time to set the concrete.

Esta prelosa autoportante consigue el canto útil necesario para la instalación de tuberías de grandes diámetros sin necesidad de modificar las dimensiones de las vigas, gracias a los salientes inferiores con los que está dotada.This self-supporting prelosa gets the useful edge necessary for the installation of large diameter pipes without need to modify the dimensions of the beams, thanks to the lower protrusions with which it is equipped.

La prelosa autoportante puede estar prefabricada en un solo bloque compacto o en varias partes, con las dimensiones adecuadas según necesidad, para que puedan ser transportadas fácilmente por carretera, cumpliendo así con la normativa vigente respecto a la circulación de elementos de grandes dimensiones.The self-supporting pre-slab can be prefabricated in a single compact block or in several parts, with the dimensions suitable as needed, so that they can be transported easily by road, thus complying with current regulations regarding the circulation of large elements.

Esta prelosa autoportante para la realización de grandes puentes o viaductos que se presenta, aporta múltiples ventajas sobre las utilizadas en la actualidad, siendo la más importante y objeto de la invención, que se aumenta las luces del puente o viaducto posibilitando la conducción de tuberías de grandes dimensiones, el canto útil que se requiere para su instalación se logra mediante los resaltes con los que está dotada, pudiendo variar su altura, según sean las dimensiones de la tubería o conducción.This self-supporting prelosa for the realization of large bridges or viaducts that is presented, provides multiple advantages over those used today, being the most important and object of the invention, that the lights of the bridge or viaduct allowing the conduction of pipes large dimensions, the useful edge that is required for your installation is achieved through the highlights with which it is equipped, being able to vary its height, depending on the dimensions of the pipe or driving

Otra importante ventaja de la presente invención es que se consigue el canto útil sin necesidad de variar las dimensiones de las vigas, reduciendo así el peso que tiene que soportar la estructura.Another important advantage of the present invention is that the useful song is achieved without changing the dimensions of the beams, thus reducing the weight that has to support the structure.

Asimismo podemos citar la ventaja añadida del ensamblaje entre la prelosa autoportante y las vigas, pues la prelosa dispone en su parte de central de unas zonas libres de material, las cuales permiten el paso de los anclajes de las vigas, facilitando su compactación al fraguarse el hormigonado.We can also cite the added advantage of assembly between the self-supporting pre-slab and the beams, as the prelosa has in its central part some areas free of material, which allow the passage of the anchors of the beams, facilitating its compaction when setting concrete.

También podemos citar como ventaja que la prelosa autoportante puede estar constituida para ser instalada sobre vigas únicas o sobre vigas dobles o adosadas, variando únicamente la distribución y salientes incorporados en la estructura de la prelosa.We can also cite as an advantage that the self-supporting pre-slab may be constituted to be installed on single beams or on double or attached beams, varying only the distribution and projections incorporated in the pre-slab structure

Finalmente citaremos como una ventaja añadida la reducción del costo, por la enorme facilidad de ensamblaje entre las diferentes partes que constituyen la viga y la prelosa autoportante.Finally we will cite as an added advantage the cost reduction, due to the enormous ease of assembly between the different parts that make up the beam and the pre-slab self-supporting
