Description
Panel aislante para cubiertas de edificios.Insulating panel for building roofs.
La invención se refiere a un panel aislante para cubiertas de edificios, y en particular para su utilización en cubiertas planas invertidas transitables, no transitables o ajardinadas.The invention relates to an insulating panel for building roofs, and in particular for use in inverted flat roofs that are passable, non-transitable or Landscaped
La característica principal de las cubiertas invertidas es que, en su construcción, la instalación del aislamiento se lleva a cabo por encima de la membrana impermeabilizante lo que impide que se produzca condensación dentro de la estructura de la cubierta. La membrana impermeable, que deviene la única barrera de vapor, queda protegida por el aislamiento térmico frente a daños mecánicos o cambios de temperatura, lo que proporciona una mayor durabilidad de la cubierta.The main feature of the covers inverted is that, in its construction, the installation of insulation is carried out above the membrane waterproofing which prevents condensation from occurring inside of the roof structure. Waterproof membrane which becomes the only vapor barrier, is protected by the thermal insulation against mechanical damage or changes in temperature, which provides greater durability of the cover.
Por lo que respecta al aislamiento, los paneles de poliestireno expandido se utilizan convencionalmente por su elevada resistencia a la difusión del vapor de agua y mínima absorción de agua, así como por su aislamiento acústico y térmico, pudiéndose obtener los paneles por proceso de extrusión o por procesos de moldeado. Usualmente, los paneles instalados son de planta rectangular y están provistos, en sus cantos laterales, de muescas y entalladuras destinados a permitir el ensamble entre paneles contiguos, los cuales se extienden sobre la membrana impermeabilizante, apoyados directamente sobre ella o con interposición de una capa o fieltro separador tipo geotextil, en disposición al tresbolillo.As regards insulation, the panels Expanded polystyrene are conventionally used for their high water vapor diffusion resistance and minimum water absorption, as well as its acoustic and thermal insulation, being able to obtain the panels by extrusion process or by molding processes Usually, the installed panels are of rectangular plan and are provided, in their lateral edges, with notches and notches intended to allow assembly between adjoining panels, which extend over the membrane waterproofing, supported directly on it or with interposition of a layer or felt separator type geotextile, in Tresbolillo disposition.
Cuando se dispone sobre los paneles aislantes grava de protección o pavimento de losas con espaciadores, el agua de lluvia es generalmente evacuada por encima de los paneles aislantes. No obstante, a pesar de la existencia de paneles provistos de acanaladuras en su superficie superior para la mejor canalización del agua, a través de las juntas entre paneles se produce una escorrentía de agua la cual alcanza la membrana impermeabilizadora, bajo el aislamiento térmico, que es susceptible de sustraer calor al forjado, lo que obliga a aumentar ligeramente el grueso de los paneles para garantizar un buen aislamiento térmico en temporadas de invierno.When disposed on insulating panels protective gravel or pavement slabs with spacers, water of rain is usually evacuated above the panels insulators However, despite the existence of panels provided with grooves on its upper surface for the best water channeling, through the joints between panels is produces a runoff of water which reaches the membrane waterproofing, under thermal insulation, which is susceptible of subtracting heat from the floor, forcing it to increase slightly the thickness of the panels to ensure good insulation thermal in winter seasons.
Por otro lado, debido a que parte del agua alcanza la membrana impermeabilizadora, se debe garantizar que ésta no quede atrapada depositada sobre la membrana, por lo que algunos paneles están provistos en su cara inferior, de apoyo sobre la membrana impermeabilizadora, de una serie de resaltes entre los cuales el agua es susceptible de discurrir en el sentido de la pendiente de la cubierta.On the other hand, because part of the water reaches the waterproofing membrane, it must be guaranteed that it do not get trapped deposited on the membrane, so some panels are provided on its underside, supporting on the waterproofing membrane, of a series of highlights between the which water is likely to run in the direction of cover slope.
Por todo ello, se hace notar la falta de un panel aislante que evite en mayor medida que el agua de lluvia alcance la membrana impermeabilizadora, y que ésta sea evacuada en más cantidad por los paneles aislantes.For all this, it is noted the lack of a insulating panel that avoids more than rainwater reach the waterproofing membrane, and that this is evacuated in more quantity for insulating panels.
El panel aislante para cubiertas de edificios, objeto de la invención, es de los fabricados por moldeo a partir de un polímero termoplástico tal como poliestireno expandido hidrófobo. Dicho panel es de planta rectangular y está provisto a lo largo de toda la longitud de dos de sus cantos contiguos de un saliente inferior en forma de escalón y en sus otros dos cantos, también a lo largo de toda su longitud, de una entalladura inferior, complementaria a los citados salientes, los cuales permiten el ensamble entre paneles por encaje de los salientes de un panel en las entalladuras de dos paneles contiguos.The insulating panel for building roofs, The object of the invention is those manufactured by molding from a thermoplastic polymer such as expanded polystyrene hydrophobe. Said panel is rectangular and is provided along the entire length of two of its contiguous edges of a lower ledge in the form of a step and in its other two edges, also along its entire length, of a lower notch, complementary to those outgoing, which allow the assemble between panels by fitting the protrusions of a panel into the notches of two adjacent panels.
El panel de la invención en esencia se caracteriza porque ambos salientes están dotados de una acanaladura en su superficie superior que se extiende longitudinalmente sobre dicha superficie, destinada para la canalización de agua, y porque la superficie superior del saliente del canto correspondiente al lado mayor del panel está provisto de al menos una muesca que se extiende desde la acanaladura hasta el borde lateral del saliente, destinada a establecer comunicación hidráulica entre dicha acanaladura y la acanaladura del canto menor de un panel contiguo.The panel of the invention essentially is characterized in that both projections are provided with a groove on its upper surface that extends longitudinally over said surface, destined for the canalization of water, and because the upper surface of the edge of the edge corresponding to the major side of the panel is provided with at least one notch that is extends from the groove to the lateral edge of the projection, intended to establish hydraulic communication between said grooving and grooving of the lower edge of a panel adjacent.
Según otra característica de la invención, el contorno de la muesca es ligeramente mayor que el contorno de la acanaladura provista en el saliente del canto correspondiente al lado de menor longitud del panel, lo que garantiza que toda el agua conducida por dicha canaladura en un panel se vierta en la acanaladura del saliente del canto correspondiente al lado de mayor longitud del panel contiguo en el que desemboca.According to another feature of the invention, the contour of the notch is slightly larger than the contour of the groove provided on the ledge of the edge corresponding to the shorter side of the panel, which ensures that all water driven by said groove in a panel being poured into the groove of the ledge of the corresponding edge to the side of major length of the adjacent panel where it ends.
Según una realización preferida, el panel está provisto de una única muesca y ésta está dispuesta equidistante de los bordes laterales extremos de la superficie superior del panel.According to a preferred embodiment, the panel is provided with a single notch and it is arranged equidistant from the extreme lateral edges of the upper surface of the panel.
De acuerdo con otra característica del panel de la invención, la superficie de su cara inferior, de apoyo, está provista de una serie de resaltes entre los cuales, estando el panel apoyado sobre una superficie esencialmente plana, es susceptible de discurrir agua.According to another feature of the panel the invention, the surface of its lower, supporting face, is provided with a series of highlights between which, the panel being supported on an essentially flat surface, it is susceptible to run water.
En los dibujos adjuntos se ilustra, a título de ejemplo no limitativo, un modo de realización del panel según la invención. En dichos dibujos:The attached drawings illustrate, by way of non-limiting example, an embodiment of the panel according to the invention. In these drawings:

la Fig. 3, es una vista de detalle de la zona III del panel de la Fig. 1.Fig. 3, is a detail view of the area III of the panel of Fig. 1.
En la Fig. 1 se ha representado un panel 1 de poliestireno expandido hidrófobo según la invención. Dicho panel 1 es de configuración esencialmente paralelepipédica, de planta rectangular, y está provisto, de un modo en sí conocido de unos medios para su ensamble o machihembrado con otros paneles contiguos.In Fig. 1 a panel 1 of hydrophobic expanded polystyrene according to the invention. Said panel 1 It is essentially parallel, plant configuration rectangular, and is provided, in a manner known per se of some Means for assembly or tongue and groove with other panels contiguous
En concreto, el panel 1 está provisto a lo largo de toda la longitud de dos cantos contiguos de un saliente inferior en forma de escalón. En efecto, el panel 1 de la Fig. 1 está provisto a lo largo de uno de sus cantos de mayor longitud del saliente 2a mientras que uno de sus cantos contiguos, de menor longitud, está provisto del saliente 2b. Al mismo tiempo, los otros dos cantos del panel 1 están provistos, también a lo largo de toda su longitud, de sendos entallamientos inferiores apreciables en la Fig. 2, en la que se ha representado el panel 1 visto inferiormente. En dicha Fig. 2 se distingue el entallamiento 5a a lo largo del canto del lado de mayor longitud y el entallamiento 5b en el canto del lado de menor longitud.Specifically, panel 1 is provided along of the entire length of two contiguous edges of a lower projection in the form of a step. Indeed, panel 1 of Fig. 1 is provided along one of its longest edges of the outgoing 2a while one of its contiguous, minor songs length, is provided with the projection 2b. At the same time, the others two edges of panel 1 are provided, also throughout its length, of two appreciable lower notches in the Fig. 2, in which the panel 1 shown below is shown. In said Fig. 2 the notch 5a is distinguished along the edge of the longest side and notch 5b in the edge of the side of shorter length.
Los entallamientos 5a y 5b son complementarios de los salientes 2a y 2b, los cuales están destinados a quedar encajados en entallamientos de paneles dispuestos contiguos, quedando los paneles ensamblados entre sí.The notches 5a and 5b are complementary of the projections 2a and 2b, which are intended to remain embedded in contours of adjacent arranged panels, the panels being assembled together.
En la Fig. 1, se aprecia que el saliente 2a está provisto de una acanaladura 3a en su superficie superior que se extiende longitudinalmente sobre dicha superficie desde uno de sus extremos hasta su extremo contrario, en tanto que el saliente 2b está provisto de una acanaladura 3b en su superficie superior que se extiende longitudinalmente desde su extremo 7 hasta la acanaladura 3a del saliente 2a del canto correspondiente al lado de mayor longitud del panel 1, desembocando dicha acanaladura 3b en la acanaladura 3a. Estas canaladuras están destinadas a canalizar el agua que desliza sobre la superficie superior del panel 1 y que cae, por efecto de la gravedad, a través de las juntas entre paneles contiguos. Esta agua es recogida y conducida por las acanaladuras 3a y 3b en el sentido de la pendiente de la cubierta. Cabe decir que, en el ejemplo de los dibujos, los paneles 1 están diseñados para ser instalados bien en la dirección de la pendiente, es decir, extendiéndose longitudinalmente en la dirección de caída del agua hasta el punto de desagüe de la cubierta, o bien transversalmente. En el primer caso, el agua recogida y canalizada por la acanaladura 3b de cada panel 1 es susceptible de ser conducida hasta la correspondiente acanaladura 3a del mismo panel, a la que desemboca uno de sus extremos, la cual tiene cierta continuidad hidráulica entre paneles contiguos dispuestos unidos a lo largo de su lado menor.In Fig. 1, it can be seen that the projection 2a is provided with a groove 3a on its upper surface which is extends longitudinally on said surface from one of its ends to its opposite end, while the projection 2b it is provided with a groove 3b on its upper surface which is extends longitudinally from its end 7 to the groove 3a of the projection 2a of the corresponding edge next to the major length of panel 1, said groove 3b leading into the 3rd groove. These gutters are intended to channel the water that slides over the top surface of panel 1 and falls, due to gravity, through the joints between panels contiguous This water is collected and conducted by grooves 3a and 3b in the direction of the slope of the roof. It is possible to say that, In the example of the drawings, panels 1 are designed to be installed well in the direction of the slope, that is, extending longitudinally in the direction of water fall to the drain point of the roof, or transversely. In the first case, the water collected and channeled through the groove 3b of each panel 1 is capable of being conducted until corresponding groove 3a of the same panel, to which it leads one of its ends, which has some hydraulic continuity between adjacent panels arranged together along its side Minor.
Debido a que es usual colocar los paneles aislantes sobre la membrana impermeabilizadora en disposición al tresbolillo, en caso de que los paneles se coloquen transversales a la dirección de la pendiente, la acanaladura 3b de los paneles carece de continuidad entre paneles contiguos por lo que el agua conducida se vertería sobre la membrana impermeabilizadora. Para evitar este inconveniente, el panel 1 de la invención está adaptado para que el agua recogida y canalizada por las acanaladuras 3b pueda ser vertida en las acanaladuras de los cantos correspondientes a los lados mayores de los paneles contiguos. A tal efecto, la superficie superior del saliente 2a del canto correspondiente al lado mayor del panel 1 está provista, a igual distancia de los bordes laterales extremos de la superficie superior del panel, de una muesca 4 que se extiende desde la propia acanaladura 3a hasta el borde lateral 9 del saliente 2a, la cual permite establecer comunicación hidráulica entre dicha acanaladura 3a y la canaladura 3b del canto correspondiente al lado menor de una panel contiguo, colocado al tresbolillo respecto al panel de referencia.Because it is usual to place the panels insulators on the waterproofing membrane available to the Tresbolillo, in case the panels are placed transverse to the direction of the slope, the groove 3b of the panels lacks continuity between adjacent panels so the water conducted would pour over the waterproofing membrane. For avoid this inconvenience, panel 1 of the invention is adapted so that the water collected and channeled by the grooves 3b can be poured into the grooves of the edges corresponding to the major sides of adjacent panels. For this purpose, the surface upper of the projection 2a of the edge corresponding to the greater side of the panel 1 is provided, at the same distance from the side edges ends of the upper surface of the panel, of a notch 4 that is extends from the groove 3a to the side edge 9 of the outgoing 2a, which allows to establish hydraulic communication between said groove 3a and the groove 3b of the edge corresponding to the minor side of an adjoining panel, placed at Tresbolillo with respect to the reference panel.
En la Fig. 3, se ha representado en detalle la zona III de la Fig. 1, observándose que la sección del pasaje de comunicación, formado por el contorno de la muesca 4, es mayor que el de las acanaladuras 3a y 3b, con lo que se garantiza que toda el agua recogida y conducida por la acanaladura 3b de un panel pueda ser vertida sobre la acanaladura 3a de un panel contiguo.In Fig. 3, the zone III of Fig. 1, observing that the section of the passage of communication, formed by the contour of the notch 4, is greater than that of the grooves 3a and 3b, which ensures that all the water collected and conducted by the groove 3b of a panel can be poured onto the groove 3a of an adjoining panel.
De colocarse los paneles 1 transversales a la dirección de la pendiente de la cubierta, indicada con la flecha A en la Fig. 1, el agua recogida por la acanaladura 3b del panel 1 será conducida hasta su extremo 7, desde donde será vertida, a través de la correspondiente muesca 4, a la acanaladura análoga a la acanaladura 3a del panel dispuesto inmediatamente a continuación y en el sentido de la circulación del agua, la cual conducirá el agua a lo largo de dicha acanaladura hasta su correspondiente acanaladura 3b, desde donde se repetirá el recorrido descrito hasta un panel contiguo situado a un nivel inmediatamente inferior.If the panels 1 are transverse to the direction of the slope of the roof, indicated by arrow A in Fig. 1, the water collected by the groove 3b of panel 1 it will be led to its end 7, from where it will be poured, to through the corresponding notch 4, to the groove analogous to the groove 3a of the panel arranged immediately below and in the sense of water circulation, which will conduct the water along said groove to its corresponding groove 3b, from where the described route to a panel will be repeated contiguous located at an immediately lower level.
En la Fig. 2 se aprecia además que el panel 1 está provisto en su cara inferior, de apoyo, de una serie de resaltes 6a y 6b esencialmente cuadrangulares y regularmente distribuidos que determinan, entre ellos, una serie de pasajes 8 para la libre circulación del agua. La disposición de los resaltes respecto de los lados del panel 1 es oblicua, por lo que también es oblicua la dirección que siguen los pasajes 8 para el agua, de modo que ésta podrá discurrir en el sentido de la pendiente tanto si los paneles se colocan longitudinal o transversalmente respecto de dicha pendiente.In Fig. 2 it is further appreciated that panel 1 it is provided on its lower, supporting face, with a series of 6a and 6b essentially quadrangular and regularly distributed that determine, among them, a series of passages 8 for the free circulation of water. The arrangement of the highlights with respect to the sides of panel 1 it is oblique, so it is also oblique the direction of passages 8 for water, so that this may run in the direction of the slope whether the panels are placed longitudinally or transversely with respect to said pending.
Se observa en dicha Fig. 2 que en las zonas próximas a los bordes del panel 1, el tamaño de los resaltes 6b es menor que en su zona central, para favorecer la circulación del agua en los puntos de ensamble entre paneles.It is observed in said Fig. 2 that in the zones next to the edges of panel 1, the size of the projections 6b is smaller than in its central zone, to favor water circulation at the assembly points between panels.
