Abstract
The aim of the invention is to prevent the door from opening in the event of a fire, thereby preserving the integrity of the protected enclosure in the face of the action of the fire, and allowing the door to be opened by the occupants of the enclosure in the event of an evacuation. The bolt for double-leaf fireproof doors consists of two metal parts: a tongue and a plate for coupling to the leaf, which are mechanically joined to the leaves of the door and face each other such that the assembly fits together perfectly when the door is closed and leaves sufficient clearance between the parts, allowing them to uncouple easily when the door is pushed. There are two further possible embodiments: a bolt formed by two similar tongues, and a bolt formed by a modified coupling part and a bracket.

PASADOR PARA PUERTAS CORTAFUEGO DE DOS HOJAS TWO-SHEET DOUBLE DOOR PIN
D E S C R I P C I Ó N D E S C R I P C I Ó N
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un nuevo pasador para puertas cortafuego de dos hojas ideado con dos objetivos: impedir que la puerta se abra en caso de incendio, preservando así la estanqueidad del recinto protegido frente a la acción del fuego, y, al mismo tiempo, permitir que la puerta sea abierta rápidamente por los ocupantes del recinto en caso de evacuación. The present invention relates to a new pin for two-leaf fire doors designed with two objectives: to prevent the door from opening in case of fire, thus preserving the tightness of the protected enclosure against the action of fire, and at the same time , allow the door to be opened quickly by the occupants of the enclosure in case of evacuation.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En el Sector de la Técnica, la invención se encuadra en el sector de la construcción, en concreto, fabricación de puertas cortafuego de dos hojas con marco de acero. In the Technical Sector, the invention falls within the construction sector, namely, the manufacture of two-leaf fire doors with a steel frame.
Los factores que deben tenerse en cuenta en el diseño de puertas cortafuego son básicamente: presión, temperatura y tiempo. Estos tres condicionantes son los que producen tanto deformaciones, como dilataciones en este tipo de puertas. The factors that must be taken into account in the design of fire doors are basically: pressure, temperature and time. These three conditions are those that produce both deformations and dilations in these types of doors.
Las deformaciones dependen del tipo de material, la temperatura y la dimensión del elemento que sufre el incendio. Estas deformaciones son causadas por los esfuerzos de pandeo y torsión, que producen alabeos y curvaturas en el conjunto de la puerta. The deformations depend on the type of material, the temperature and the size of the element that suffers the fire. These deformations are caused by the buckling and twisting efforts, which produce warps and curvatures in the door assembly.
Las mayores deformaciones se encontrarán en el área central de la puerta, zona donde se sitúa la cerradura, de forma que la acción del fuego abre la puerta si estos esfuerzos mecánicos no quedan impedidos.
En el Estado de la Técnica son sobradamente conocidos los dispositivos de cierre de puertas, que cierran la puerta manualmente. Es el caso de los pasadores tipo pestillo, cerrojo o de falleba, que se caracterizan por tener un elemento pasante o vástago, que recorre una pequeña distancia hasta encajarse en la pieza de retención y suelen tener un seguro diseñado mediante muelles, ganchos, piezas especiales u otros elementos. Este tipo de pasadores presentan el inconveniente de que necesitan ser abiertos también de forma manual cuando se desea desbloquear la puerta. Así, en una evacuación en caso de incendio, los ocupantes del recinto afectado tendrían que interrumpir el recorrido de evacuación para pararse a desbloquear la puerta y poder salir, lo cual, además de no estar permitido según la normativa vigente (CTE DA DB- SI / 3, artículo 2), supone una gran incoherencia. The greatest deformations will be found in the central area of the door, the area where the lock is located, so that the action of fire opens the door if these mechanical efforts are not prevented. In the prior art, the door closing devices, which close the door manually, are well known. This is the case of the latch, bolt or flap pins, which are characterized by having a through element or rod, which travels a small distance to fit in the retention piece and usually have a safety designed by means of springs, hooks, special pieces or other elements. These types of pins have the disadvantage that they also need to be opened manually when you want to unlock the door. Thus, in an evacuation in case of fire, the occupants of the affected area would have to interrupt the evacuation route to stop to unlock the door and be able to leave, which, in addition to not being allowed according to current regulations (CTE DA DB-SI / 3, article 2), is a great inconsistency.
Tal es el caso de las invenciones ES 1 025 338 U y ES 1 018 296 U, que consisten en un vástago que se desliza longitudinalmente y fija las hojas de la puerta cerrándolas, pero presentan el inconveniente de que este tipo de dispositivos impiden la evacuación de los ocupantes en un recinto en caso de incendio, ya que si la puerta se encuentra cerrada, no se puede desbloquear empujándola sencillamente, sino que se ha de devolver el pasador a la posición opuesta para poder salir, lo cual impide el paso libre de los ocupantes por una vía de evacuación hacia la salida, por lo que además, estas invenciones no se incluyen en el sector de la técnica de la presente invención. Otro problema que presentan estas invenciones es que no son regulables horizontal y verticalmente, de forma que a veces se producen fallos debidos a la instalación de estos pasadores, pues las diferentes piezas no llegan a adaptarse unas a otras perfectamente. Such is the case of the inventions ES 1 025 338 U and ES 1 018 296 U, which consist of a rod that slides longitudinally and fixes the door leaves closing them, but they have the disadvantage that such devices prevent evacuation. of the occupants in an enclosure in case of fire, since if the door is closed, it cannot be unlocked by simply pushing it, but the pin must be returned to the opposite position to be able to exit, which prevents the free passage of occupants by an evacuation route to the exit, therefore, these inventions are not included in the field of art of the present invention. Another problem presented by these inventions is that they are not adjustable horizontally and vertically, so that sometimes failures due to the installation of these pins occur, because the different pieces do not adapt perfectly to each other.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La invención consiste en un pasador regulable para puertas cortafuego de doble hoja, ideado con la intención de resolver los problemas planteados: asegurar el cierre de la puerta en caso de incendio; preservando el recinto protegido y las propiedades mecánicas de la puerta cortafuegos y permitir, a la vez, la salida de los
ocupantes del recinto a un espacio seguro, respetando así la normativa vigente. The invention consists of an adjustable pin for double-leaf fire doors, designed with the intention of solving the problems posed: ensuring the closing of the door in case of fire; preserving the protected enclosure and the mechanical properties of the fire door and allowing, at the same time, the exit of the occupants of the enclosure to a safe space, thus respecting current regulations.
Estas piezas se atornillan en la parte central de la puerta, concretamente, en los laterales de cerradura y contracerradura respectivamente: al lateral de cerradura de la puerta se le atornilla la lengüeta que es una pieza fabricada en metal con sección en forma de Z, mientras que al lateral de contracerradura, se le atornilla la chapa de enganche, que es una pieza fabricada en metal con sección en forma de greca. Está previsto que estas piezas sean regulables, de forma que puedan ensamblarse perfectamente una a la otra, evitando así posibles fallos en la instalación. Esta regulación se consigue gracias al diseño de las secciones de ambas piezas. De esta forma, el pasador actuará al cerrar y abrir la puerta, ya que la lengüeta entra en la chapa de enganche al cerrar y sale de ella al abrir, eliminando la necesidad de incluir ningún otro accesorio a la presente invención. El mecanismo de acción del pasador es muy sencillo: al cerrarse la puerta, las dos piezas se enganchan encajando perfectamente, pero permitiendo una holgura entre ellas suficiente para que, al abrir la puerta mediante la manilla o la barra antipánico, se desenganchen sin esfuerzo para los ocupantes del recinto que intentan salir. Así, se permite la apertura de las hojas de forma normal; una persona cualquiera no notaría la diferencia entre que el pasador estuviera colocado o no, pero en caso de incendio, la invención actúa como mecanismo de seguridad mientras la puerta está cerrada, ejerciendo un bloqueo adicional que impide que la puerta se abra por acción del fuego. La lengüeta, que representa la principal novedad de la invención, se desliza dentro de la pieza de enganche cuando la puerta abre y cierra, sin la necesidad de instalar ningún otro elemento más, de forma que el tiempo de instalación respecto a otras soluciones que incorporan un vástago, es menor. Esta invención también mejora la integridad de la puerta frente al fuego, ya
que, estructuralmente, el pasador supone un punto de coacción que permite el giro, pero impide los desplazamientos verticales y horizontales en ese punto, de forma que hablaríamos de un punto de apoyo estructural. Esto implica que en caso de incendio, la puerta en ese punto ofrecerá más resistencia a la deformación, concretamente al pandeo y la torsión, y tenderá a soportar la acción del fuego sin abrirse durante más tiempo. These pieces are screwed in the central part of the door, specifically, on the lock and counter lock sides respectively: the tongue which is a piece made of metal with a Z-shaped section is screwed to the door lock side, while that the hitch plate is screwed to the counter-lock side, which is a piece made of metal with a fret-shaped section. It is planned that these parts are adjustable, so that they can be perfectly assembled to each other, thus avoiding possible installation failures. This regulation is achieved thanks to the design of the sections of both pieces. In this way, the pin will act when closing and opening the door, since the tongue enters the latch plate when closing and leaves it when opening, eliminating the need to include any other accessory to the present invention. The mechanism of action of the pin is very simple: when the door is closed, the two pieces hook together perfectly, but allowing a sufficient clearance between them so that, when opening the door by means of the handle or the panic bar, they unhook effortlessly to the occupants of the enclosure trying to leave. Thus, the opening of the leaves is allowed in a normal way; Any person would not notice the difference between the pin being placed or not, but in case of fire, the invention acts as a safety mechanism while the door is closed, exerting an additional lock that prevents the door from opening by fire. . The tongue, which represents the main novelty of the invention, slides inside the coupling part when the door opens and closes, without the need to install any other element, so that the installation time with respect to other solutions that incorporate A stem is smaller. This invention also improves the integrity of the door against fire, since that, structurally, the pin supposes a point of constraint that allows the rotation, but prevents vertical and horizontal displacements at that point, so that we would talk about a structural support point. This implies that in case of fire, the door at that point will offer more resistance to deformation, specifically to buckling and twisting, and will tend to withstand the action of fire without opening for longer.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
La invención se aplica a puertas cortafuego de dos hojas con marco de acero, donde las piezas del pasador se fijan a la puerta en la parte central, concretamente en el lateral central de cada una de las hojas: primaria (4) y secundaria (1). Está previsto que
se coloquen uno o varios pasadores atornillados a las hojas de la puerta. The invention applies to two-leaf fire doors with steel frames, where the pin parts are fixed to the door in the central part, specifically in the central side of each of the leaves: primary (4) and secondary (1 ). It is planned that one or several pins bolted to the door leaves.
Una vez que la puerta esté instalada en obra, con las dos hojas montadas en el marco y reguladas, se acoplará a ellas el pasador. Se prevé que, en primer lugar, se atornille la pieza de enganche, la cual está fabricada en metal y tiene sección en forma de greca (2) en el lateral de contracerradura de la hoja secundaria (1), perforando la hoja y, una vez que esta pieza esté fija, se atornille análogamente la lengüeta, que está fabricada en metal y tiene sección en Z (3) en el punto homólogo de la hoja primaria (4). Las piezas deben atornillarse mediante los agujeros predispuestos (6) que permiten la regulación necesaria, vertical y horizontal, para que las piezas se ensamblen perfectamente: deben quedar enfrentadas en la zona central de la puerta, de forma que cuando cierren las dos hojas, las piezas se acoplan, ya que la lengüeta (3) entrará en la pieza de enganche (2) de forma natural. La pieza de enganche (2) actúa como enlace de la contraria, ya que su forma en forma de greca le permite acoplarse a la hoja de la puerta (4) dejando un espacio libre en donde la lengüeta (3) puede ensamblarse. Esta lengüeta (3) se ha estudiado de forma que el plegado de la sección en Z le permita acoplarse al enganche (2) y que, a la vez, permita que se separe de forma natural al empujar la puerta (1). Once the door is installed on site, with the two leaves mounted on the frame and regulated, the pin will be attached to them. It is envisaged that, in the first place, the coupling piece is screwed, which is made of metal and has a fret-shaped section (2) on the counter-lock side of the secondary leaf (1), perforating the leaf and, a Once this piece is fixed, the tongue, which is made of metal and has a Z-section (3) at the homologous point of the primary sheet (4), is screwed in analogously. The pieces must be screwed through the predisposed holes (6) that allow the necessary vertical and horizontal adjustment so that the pieces are assembled perfectly: they must face each other in the central area of the door, so that when they close the two sheets, the pieces are coupled, since the tongue (3) will enter the coupling piece (2) naturally. The coupling piece (2) acts as a link to the opposite, since its shape in the form of a fret allows it to be attached to the door leaf (4) leaving a free space where the tongue (3) can be assembled. This tab (3) has been studied so that the folding of the Z section allows it to be coupled to the hitch (2) and, at the same time, allows it to separate naturally when pushing the door (1).
Una segunda opción para la realización de la invención es que en lugar de una pieza de enganche y una lengüeta, se atornillen a la hoja primaria (4) y secundaria (1) dos lengüetas con sección en forma de Z y realizadas en metal (5) semejantes mediante agujeros predispuestos (6), que permiten la regulación perfecta de las piezas, tanto en vertical como en horizontal. A second option for the realization of the invention is that instead of a hitch piece and a tongue, two tabs with a Z-shaped section and made of metal (5) are screwed to the primary (4) and secondary (1) sheet. ) similar by means of predisposed holes (6), which allow the perfect regulation of the pieces, both vertically and horizontally.
Una tercera opción para la realización de la invención es que se atornille a la hoja secundaria (1) una pieza de enganche modificada metálica (7) con un recorte tal que permita que un corchete de metal (8) fijado en la hoja secundaria (4) se enganche en ella y que, a la vez, se separa de forma natural al empujar la puerta (1 ).
Descrita suficientemente la naturaleza de la presente invención, así como la manera de ponerla en práctica, no se considera necesario hacer más extensa su explicación para que cualquier experto en la materia comprenda su alcance y las ventajas que de ellas se derivan, haciéndose constar que, dentro de su esencialidad, podrá ser llevada a la práctica en otras formas de realización que difieran en detalle de la indicada a título de ejemplo, y a las cuales alcanzará igualmente la protección que se recaba siempre que no se altere, cambie o modifique su principio fundamental.
A third option for the realization of the invention is that a metal modified hitch piece (7) is screwed to the secondary sheet (1) with a cut such that it allows a metal bracket (8) fixed on the secondary sheet (4) ) hooks on it and, at the same time, separates naturally by pushing the door (1). Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make its explanation more extensive so that any person skilled in the art understands its scope and the advantages derived therefrom, stating that, within its essentiality, it may be carried out in other embodiments that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is sought provided that it does not alter, change or modify its fundamental principle .
