Description

DESCRIPCIÓN  DESCRIPTION

FACHADA MODULAR. Objeto de la invención MODULAR FACADE. Object of the invention

La presente invención se refiere a una fachada modular para construcciones prefabricadas que comprende unos módulos conformados por una estructura metálica reforzada, con travesanos y largueros, dotada de unos medios de fijación mutua y con los forjados adyacentes, y unos medios de estanqueidad; presentando estos módulos un relleno de la estructura con placas de material aislante y un recubrimiento de varias capas.  The present invention relates to a modular facade for prefabricated constructions comprising modules formed by a reinforced metal structure, with crossbars and stringers, provided with means of mutual fixation and with adjacent slabs, and sealing means; presenting these modules a filling of the structure with plates of insulating material and a coating of several layers.

Campo de aplicación de la invención. Field of application of the invention.

Esta fachada es aplicable en la industria de la construcción de edificios.  This facade is applicable in the building construction industry.

Antecedentes de la invención. Background of the invention.

La construcción convencional de edificaciones comprende la realización de obras que se dilatan en el tiempo al utilizar técnicas de construcción "in situ" con la necesidad de utilizar un gran número de albañiles y personal especializado, comprendiendo el uso de hormigón, arena, vigas, agua y otros materiales.  The conventional construction of buildings includes the construction of works that expand over time by using construction techniques "in situ" with the need to use a large number of bricklayers and specialized personnel, including the use of concrete, sand, beams, water and other materials.

También son utilizadas en la construcción de paredes exteriores, planchas de hormigón prefabricadas, que se introducen verticalmente a modo de corredera entre pilares consecutivos, realizándose el remate de las uniones mediante morteros, o pastas fraguables.  They are also used in the construction of exterior walls, prefabricated concrete slabs, which are introduced vertically as a slide between consecutive pillars, making the closing of the joints by mortars, or fragile pastes.

Actualmente también es conocida, la construcción de paredes "in situ", mediante la conformación y fijación a la obra de estructuras metálicas ligeras, de baja resistencia mecánica, y el recubrimiento de dicha estructura ligera con paneles de diferentes materiales, sobre los que se aplica una capa de mortero, siendo preciso proporcionarle a la superficie un acabado pintado.  Currently it is also known, the construction of walls "in situ", through the conformation and fixation to the work of light metal structures, of low mechanical resistance, and the coating of said light structure with panels of different materials, on which it is applied a layer of mortar, being necessary to give the surface a painted finish.

El rellenado de las juntas entre módulos consecutivos, y entre los módulos y la obra, se realiza igualmente con masas fraguables lo que determina que la superficie exterior no sea continua, y se vea deteriorada rápidamente, con la aparición de grietas, tanto en los módulos como en las zonas de las juntas, debido a las contracciones y dilataciones originadas por los cambios térmicos. The filling of the joints between consecutive modules, and between the modules and the work, is also carried out with fragile masses which determines that the exterior surface is not continuous, and is quickly deteriorated, with the appearance of cracks, both in the modules and in the areas of the joints, due to contractions and dilations caused by thermal changes.

La conformación de la estructura con perfiles metálicos ligeros determina que sea más ligera, y por lo tanto más deformable con los movimientos y asentamientos del edificio, propiciando la aparición de grietas en las capas de recubrimiento exterior.  The conformation of the structure with light metal profiles determines that it is lighter, and therefore more deformable with the movements and settlements of the building, leading to the appearance of cracks in the outer covering layers.

Además, estos módulos fabricados comprenden en su construcción capas de materiales no transpirables, tales como materiales plásticos de impermeabilización, por lo que acumulan humedad por condensación en el interior de la edificación.  In addition, these manufactured modules comprise in their construction layers of non-breathable materials, such as plastic waterproofing materials, so they accumulate moisture by condensation inside the building.

La fabricación "in situ" de estos módulos supone adicionalmente un incremento del tiempo de construcción, debido a factores climatológicos que impiden la aplicación del recubrimiento exterior y suponen una perdida importante de horas de trabajo de los operarios.  The manufacturing "in situ" of these modules additionally implies an increase in construction time, due to weather factors that prevent the application of the exterior coating and imply a significant loss of working hours of the operators.

Descripción de la invención Description of the invention

La fachada modular, objeto de esta invención, presenta unas particularidades técnicas destinadas a mejorar el acabado y durabilidad de la edificación, con una operativa de construcción limpia y sin usar agua o materiales fraguables, mejorando el rendimiento y la calidad obtenida. Esta fachada utiliza nuevos materiales que permite obtener mejores prestaciones.  The modular façade, object of this invention, presents some technical peculiarities aimed at improving the finish and durability of the building, with a clean construction operation and without using water or forged materials, improving the performance and quality obtained. This facade uses new materials that allow to obtain better benefits.

La fachada modular es del tipo de las que comprenden unos módulos prefabricados adosables al exterior de un edificio.  The modular facade is of the type that includes prefabricated modules attached to the exterior of a building.

De acuerdo con la invención, la fachada modular comprende unos módulos prefabricados conformados por una estructura metálica reforzada con travesaños y largueros, dotada de unos medios de fijación mutua, presentando estos módulos un relleno de la estructura con placas de material aislante dispuestas entre los travesaños y los largueros, y un recubrimiento de varias capas en su cara exterior  According to the invention, the modular façade comprises prefabricated modules formed by a metal structure reinforced with crossbars and stringers, provided with means of mutual fixation, these modules presenting a filling of the structure with plates of insulating material arranged between the crossbars and the stringers, and a multilayer coating on its outer face

El recubrimiento comprende unos paneles de madera sobre al menos una cara de la estructura metálica, protegidos con una lámina de papel antihumedad, sobre la cual se encuentra una malla metálica de adherencia de una capa de mortero seco proyectado y un acabado superficial exterior, siendo todas las capas y el acabado superficial exterior transpirables. Al ser transpirables las diversas capas que conforman el módulo se posibilita el paso del vapor de agua producido naturalmente en el interior de la edificación, evitando que condense y que forme humedades. La hoja de papel antihumedad protege el panel de madera de las humedades exteriores. A su vez, la malla metálica proporciona agarre del mortero seco a los otros materiales y evita la formación de microfisuras e otros signos de deterioro. The coating comprises wooden panels on at least one face of the metal structure, protected with a sheet of anti-humidity paper, on which is a metal mesh of adhesion of a layer of projected dry mortar and an exterior surface finish, all being Breathable outer layers and surface finish. Being breathable the various layers that make up the module allows the passage of water vapor produced naturally inside the building, preventing it from condensing and forming moisture. The anti-humidity paper sheet protects the wooden panel from external moisture. In turn, the metal mesh provides dry mortar grip to the other materials and prevents the formation of microcracks and other signs of deterioration.

Dichos módulos comprenden unos medios de fijación mutua de las estructuras de módulos consecutivos que permite establecer la continuidad horizontal de forma garantizada. Además, entre los módulos se encuentran unos medios de estanqueidad que evitan la filtración de humedades entre módulos desde el exterior al interior de la fachada.  Said modules comprise means of mutual fixation of the structures of consecutive modules that allow to establish horizontal continuity in a guaranteed way. In addition, between the modules there are sealing means that prevent the filtration of humidity between modules from the outside to the inside of the facade.

Para la colocación de la fachada, los módulos comprenden unos medios de sujeción al edificio, que pueden ser de cualquier índole, sujetándose principalmente al borde exterior del forjado principalmente.  For the placement of the façade, the modules comprise means for fastening the building, which can be of any kind, being mainly attached to the outer edge of the slab, mainly.

Los medios de fijación entre los módulos adyacentes están constituidos por unas orejetas distribuidas en los laterales verticales de la cara interior de dichas estructuras para su unión con las orejetas de los módulos consecutivos mediante unos tornillos. Estas orejetas permiten el montaje directo de los módulos, sin utilizar morteros o pastas fraguables de fijación, con lo que no es necesaria utilizar agua en esta fase de la construcción, ni esperar al fraguado. Además el acoplamiento mediante tornillos es sencillo y facilita la realización de uniones rápidas.  The fixing means between the adjacent modules are constituted by lugs distributed on the vertical sides of the inner face of said structures for their union with the lugs of the consecutive modules by means of screws. These lugs allow the direct assembly of the modules, without using mortars or settable fixing pastes, so it is not necessary to use water in this phase of the construction, nor wait for setting. In addition, the coupling by screws is simple and facilitates the realization of quick joints.

A su vez, , los medios de estanqueidad están constituidos por una junta longitudinal flexible, de sección en forma de "V", y un tapajuntas exterior, de sección en "T", estando este tapajuntas parcialmente introducido en el interior de la junta longitudinal por su porción central, quedando la porción plana del tapajuntas superpuesta sobre las caras exteriores de los módulos adyacentes. De esta forma se evita la necesidad de utilizar materiales fraguables o morteros en la unión entre módulos. Además, la junta flexible absorbe los movimientos relativos de los distintos módulos evitando tensiones entre ellos, y el tapajuntas exterior oculta la zona de unión entre módulos.  In turn, the sealing means are constituted by a flexible longitudinal joint, with a "V" shaped section, and an external flashing, with a "T" section, this joint being partially inserted inside the longitudinal joint. by its central portion, the flat portion of the flashing being superimposed on the outer faces of the adjacent modules. This avoids the need to use forged materials or mortars in the joint between modules. In addition, the flexible joint absorbs the relative movements of the different modules avoiding tensions between them, and the outer flashing hides the joint area between modules.

En una realización el acabado superficial exterior comprende una capa de fijador o sellador, una capa de goma transpirable y una capa de revestimiento siloxánico. Este revestimiento siloxánico es un mineral artificial, más económico que un revestimiento de silicatos, que es totalmente transpirable y mantiene su color sin degradación durante un largo periodo de tiempo, ahorrando el pintado final requerido por los módulos construidos "in situ" y los posteriores repasos o retoques de pintura. In one embodiment, the outer surface finish comprises a fixative or sealant layer, a breathable rubber layer and a siloxane coating layer. This siloxane coating is an artificial mineral, cheaper than A silicate coating, which is fully breathable and maintains its color without degradation for a long period of time, saving the final painting required by the modules built "in situ" and subsequent revisions or touch-ups of paint.

El panel de madera es un panel OSB o panel de virutas de madera orientadas. Este panel OSB es mecánicamente estable y ligero.  The wood panel is an OSB panel or panel of oriented wood chips. This OSB panel is mechanically stable and lightweight.

La precisión dimensional que se consigue con la elaboración de los módulos en fábrica, y permite la posterior instalación de los módulos en la fachada en construcción de una forma rápida, sin imprevistos ni problemas de acoplamiento.  The dimensional precision that is achieved with the manufacturing of the modules in the factory, and allows the subsequent installation of the modules on the facade under construction quickly, without any unforeseen or coupling problems.
