ELEMENTOS ELEMENTS
La presente invención se refiere a un procedimiento de fabricación de elementos de forjado bidireccionales aligerados y aislados térmicamente. La invención también se refiere a una estructura de forjado bidireccional obtenida con dichos elementos. The present invention relates to a method of manufacturing lightened and thermally insulated bidirectional forging elements. The invention also relates to a bidirectional forging structure obtained with said elements.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Son conocidos los elementos de forjado bidireccionales prefabricados de hormigón armado y provistos de aislamiento térmico, obtenidos industrialmente y cuyo objetivo es el de aumentar el control en la calidad del elemento acabado y disminuir el tiempo de instalación, reduciendo al mínimo las acciones que quedan a la casualidad de la obra. The prefabricated reinforced concrete and industrial insulated bi-directional forged elements are known, industrially obtained and whose objective is to increase the quality control of the finished element and decrease the installation time, minimizing the remaining actions coincidence of the work.
Son ejemplos de estos elementos los descritos en los documentos FR1509229 y US3918222.  Examples of these elements are those described in documents FR1509229 and US3918222.
En el primero de ellos se describen elementos de forjado bidireccionales prefabricados de hormigón armado y provistos de aislamiento térmico.  In the first one, prefabricated reinforced concrete bidirectional slab elements and provided with thermal insulation are described.
Asimismo, se describe el procedimiento de obtención de estos, que se realiza por posicionamiento de los encofrados, colocación de la armadura y posterior relleno con hormigón. Opcionalmente, los encofrados pueden quedar perdidos en el hormigón, y pueden tener propiedades de aislamiento térmico.  Likewise, the procedure for obtaining these is described, which is carried out by positioning the formwork, placing the reinforcement and subsequent filling with concrete. Optionally, the formwork can be lost in the concrete, and can have thermal insulation properties.
Sin embargo, este procedimiento presenta el inconveniente de la complejidad de fabricación del elemento, muy especialmente debido a la necesidad de gestionar individualmente, en especial para posicionarlos entre sí, los encofrados.  However, this procedure has the disadvantage of the complexity of manufacturing the element, especially due to the need to manage the formwork individually, especially to position them together.
Por otro lado, en este documento, la unión del elemento de forjado obtenido a la jácena también es complicado, y se basa en la utilización de tornillos que trabajan a esfuerzo cortante. Además, la unión obtenida precisa de una etapa posterior de acabado.  On the other hand, in this document, the joining of the forged element obtained to the japan is also complicated, and is based on the use of screws that work at shear. In addition, the union obtained requires a later stage of finishing.
El segundo documento también propone elementos de forjado bidireccionales prefabricados en los cuales el apoyo sobre las jácenas se hace sobre unas pestañas de hormigón perimetrales. Sin embargo, el sistema descrito presenta el inconveniente de precisar una estructura especialmente adaptada, en lo que se refiere a la forma de los apoyos, para los elementos prefabricados. Tampoco soluciona el problema del aislamiento térmico. The second document also proposes prefabricated bidirectional forging elements in which the support on the jácenas is made on perimetral concrete tabs. However, the described system has the disadvantage of specifying a specially adapted structure, in terms of the shape of the supports, for the prefabricated elements. Nor does it solve the problem of thermal insulation.
Por lo tanto, los inventores consideran que las soluciones relativas a elementos de forjado bidireccionales aligerados del estado de la técnica no solucionan inconvenientes ligados a facilidad y rapidez de construcción, calidad y completitud del elemento acabado y propiedades de aislamiento térmico de estos.  Therefore, the inventors consider that the solutions related to lightened bidirectional forging elements of the prior art do not solve drawbacks linked to ease and speed of construction, quality and completeness of the finished element and thermal insulation properties of these.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
Para ello, la presente invención propone un procedimiento de fabricación de elementos de forjado bidireccionales prefabricados de hormigón armado y provistos de aislamiento térmico, que comprende las etapas de: For this, the present invention proposes a manufacturing process for prefabricated reinforced concrete bidirectional slab elements and provided with thermal insulation, comprising the steps of:

c) Verter el hormigón en dichos canales,  c) Pour the concrete into these channels,
d) Retirar conjuntamente la pieza y el hormigón fraguado,  d) Remove the piece and the set concrete together,
De modo que se obtiene un elemento de forjado bidireccional aligerado que incorpora un aislamiento.  So that a lightened bidirectional forging element that incorporates an insulation is obtained.
El procedimiento permite obtener en un menor número de etapas un elemento de forjado prefabricado armado que ya incorpora el aislamiento.  The procedure allows to obtain in a smaller number of stages an element of prefabricated reinforced slab that already incorporates the insulation.
El elemento obtenido tiene un nivel de aislamiento térmico elevado, evitando al máximo los puentes térmicos en dirección vertical, muy especialmente gracias a la estructura de placa provista de paralelepípedos.  The element obtained has a high level of thermal insulation, avoiding thermal bridges in the vertical direction, especially thanks to the plate structure provided with parallelepipeds.
El procedimiento permite emplear piezas de encofrado/ aislamiento monobloque de gran tamaño, de modo que se minimizan las tareas de posicionamiento mencionados en los antecedentes, aumentándose la velocidad de fabricación y la precisión en las dimensiones del elemento obtenido.  The procedure allows the use of large-size monobloc formwork / insulation pieces, so that the positioning tasks mentioned in the background are minimized, increasing manufacturing speed and precision in the dimensions of the element obtained.

La disposición de los elementos en el elemento de anclaje permite colocar los elementos prefabricados apoyados en las jácenas, de modo que las vigas y los elementos ocupan el mismo espacio en proyección vertical.  The arrangement of the elements in the anchoring element makes it possible to place the prefabricated elements supported by the beams, so that the beams and the elements occupy the same space in vertical projection.
En los procedimientos del estado de la técnica, la unión de los elementos a la estructura se complica durante la colocación de estos en la estructura, por ejemplo en la fase de atornillado descrito en la patente francesa, o de preparación de jácenas adaptadas de la segunda patente mencionada.  In the state of the art procedures, the joining of the elements to the structure is complicated during their placement in the structure, for example in the bolting phase described in the French patent, or in the preparation of taps adapted from the second mentioned patent.

a- Disponer horizontalmente una pieza 2 con propiedades de aislamiento térmico en el fondo de un encofrado E, representado en sección en la figura 1 , donde esta pieza 2 es una matriz M de paralelepípedos 3 sobre una placa rectangular 4, de modo que se configura una red de canales 5 perpendiculares entre sí para la recepción del hormigón H,  a- Horizontally arrange a piece 2 with thermal insulation properties at the bottom of a formwork E, shown in section in figure 1, where this piece 2 is a matrix M of parallelepipeds 3 on a rectangular plate 4, so that it is configured a network of channels 5 perpendicular to each other for the reception of concrete H,
b- Disponer la armadura A en los canales 5 que se configuran entre los paralelepípedos,  b- Armor A in the channels 5 that are configured between the parallelepipeds,
c- Verter el hormigón H en los canales 5,  c- Pour concrete H into channels 5,
d- Retirar conjuntamente la pieza 2 y el hormigón fraguado H. d- Remove part 2 and set concrete H.
De este modo, se obtiene un elemento de forjado bidireccional 1 aligerado que incorpora un aislamiento 2 como los que se ilustran en las figuras 7a y 7b. In this way, a lightened bidirectional forging element 1 is obtained that incorporates an insulation 2 such as those illustrated in Figures 7a and 7b.
Estas dos variantes se diferencian en que en la primera de ellas el producto acabado presenta un cerco de hormigón, mientras que en la segunda, la estructura de hormigón acaba lateralmente en extremos que sobresalen.  These two variants differ in that in the first of them the finished product has a concrete fence, while in the second, the concrete structure ends laterally at protruding ends.
Por lo tanto, ambas se diferencian en la relación hormigón/ aislamiento, siendo la relación más baja para el de la segunda realización representada en la figura 7b, la cual constituye la opción preferida.  Therefore, both differ in the concrete / insulation ratio, the lowest ratio being that of the second embodiment represented in Figure 7b, which constitutes the preferred option.
Se destaca que en las figuras 1 a 5 se ha descrito la fabricación de los elementos según la primera realización, pero resulta obvio extenderla a elementos según la segunda realización.  It is noted that in Figures 1 to 5 the manufacture of the elements according to the first embodiment has been described, but it is obvious to extend it to elements according to the second embodiment.
Preferentemente, tras la etapa c se prevé una etapa consistente en disponer en los extremos de algunos canales 5, o preferentemente todos, unos elementos de apoyo 6 provistos de una pestaña de apoyo 6a que sobresale lateralmente del elemento 1 por sus bordes superiores.  Preferably, after stage c, a stage is provided consisting of having at the ends of some channels 5, or preferably all, support elements 6 provided with a support flange 6a protruding laterally from the element 1 by its upper edges.
Esta pestaña, tal como se ilustra en la figura 8, servirá de apoyo del elemento obtenido sobre las jácenas J. A estar dispuesta en los bordes superiores, el elemento se dispondrá con su superficie superior enrasada con la superficie superior de la jácena, con lo cual la ocupación en la dirección vertical será la misma tanto en el elemento de forjado como en la estructura de apoyo, lo cual permitirá obtener directamente amplias superficies planas continuas.  This flange, as illustrated in Figure 8, will support the element obtained on the jácenas J. To be arranged on the upper edges, the element will be arranged with its upper surface flush with the upper surface of the jácena, with which the occupation in the vertical direction will be the same both in the forging element and in the support structure, which will allow to obtain directly large continuous flat surfaces.
La invención también aporta una realización inventiva de estos elementos de apoyo.  The invention also provides an inventive embodiment of these support elements.
Concretamente, tal como se aprecia en las figuras 9 y 10, los elementos de apoyo 6 comprenden una placa metálica 6b, estando dicha pestaña de apoyo 6a constituida por el tramo sobresaliente de dicha placa 6b. Specifically, as seen in Figures 9 and 10, the support elements 6 comprise a metal plate 6b, said support flange 6a being constituted by the projecting section of said plate 6b.
Extendiéndose desde la superficie inferior de la placa 6 hay dos anclajes destinados a estar embebidos en el hormigón H, un primero de ellos 6c perpendicular a la placa 6b, y el segundo 6d formando un ángulo de 45° con el primero 6c.  Extending from the lower surface of the plate 6 there are two anchors intended to be embedded in the concrete H, a first 6c perpendicular to the plate 6b, and the second 6d at an angle of 45 ° with the first 6c.
El primer anclaje tiene por función tiene como función garantizar el buen estribado del nervio y aumentar la solidaridad entre el apoyo y el hormigón.  The first anchor has the function of guaranteeing the good ribbing of the nerve and increasing the solidarity between the support and the concrete.
El segundo anclaje, está preferentemente con cordones de soldadura y su dirección a 45° cose la fisura cortante teórica del nervio en esfuerzo cortante.  The second anchor is preferably with weld seams and its 45 ° direction sews the theoretical shear fissure of the nerve in shear stress.
Preferentemente, tal como se aprecia en las figuras 9 y 10, el primer anclaje 6c es una patilla en forma de U y el segundo anclaje 6d son dos patillas, y más preferentemente, las patillas se prolongan mediante sendos tramos 6e paralelos a la placa, de modo que el segundo anclaje 6d está doblado formando un ángulo de 135°.  Preferably, as seen in Figures 9 and 10, the first anchor 6c is a U-shaped pin and the second anchor 6d is two pins, and more preferably, the pins are extended by sections 6e parallel to the plate, so that the second anchor 6d is folded at an angle of 135 °.
Tal como se puede apreciar en la figura 8, con los elementos obtenidos mediante el procedimiento de la invención se puede construir en un tiempo mínimo una estructura de forjado bidireccional, donde los elementos de forjado prefabricados modulares se apoyan sobre la superficie superior de unas jácenas J mediante dichos elementos de apoyo 6.  As can be seen in Figure 8, with the elements obtained by the process of the invention, a bidirectional floor structure can be constructed in a minimum time, where the modular prefabricated floor elements are supported on the upper surface of a few Js. through these support elements 6.
Cuando los elementos integran el pavimento y el falso techo, una vez dispuestos los elementos, el forjado integra todas las capas, especialmente la de aislamiento térmico, y además queda a la misma altura que las jácenas que lo sostienen.  When the elements integrate the pavement and the false ceiling, once the elements are arranged, the slab integrates all the layers, especially the thermal insulation, and is also at the same height as the jácenas that support it.
