La invención contempla tanto los componentes del propio balcón como los elementos específicos de unión entre el mismo y los forjados existentes del edificio, que se diseñan de forma específica para posibilitar un montaje y desmontaje cuando el edificio ya está ejecutado.The object of the present invention, as its title establishes, is a light and removable prefabricated balcony to be incorporated into a building already executed and in service, which allows the built area available for its inhabitants to be expanded. The invention contemplates both the components of the balcony itself and the specific joining elements between it and the existing slabs of the building, which are specifically designed to allow assembly and disassembly when the building is already built.

Caracteriza al presente desarrollo la especial configuración y disposición de conjunto de una serie de elementos para conseguir el fin de obtener un balcón prefabricado ligero y desmontable capaz de poder adosarse a forjados de edificios ya existentes, lo que por una parte evita el empleo de costosas piezas de encofrado en voladizo que se requieren cuando los balcones se construyen a la vez que el edificio, permite ampliar de forma económica la superficie construida disponible para los pisos que conforman un edificio ya ejecutado y además posibilita un desmontaje sencillo que favorece el traslado y reutilización del mismo balcón prefabricado en el caso de que se requiera, sin requerirse operaciones de reacondicionamiento o tener que volverlo a fabricar.The present development is characterized by the special configuration and joint arrangement of a series of elements to achieve the goal of obtaining a light and removable prefabricated balcony capable of being attached to existing building slabs, which on the one hand avoids the use of expensive pieces of cantilever formwork that are required when the balconies are built at the same time as the building, it allows economically expanding the constructed area available for the floors that make up a building that has already been completed and also allows easy disassembly that favors the transfer and reuse of the same prefabricated balcony in the event that it is required, without requiring reconditioning operations or having to re-manufacture it.

Por lo tanto, la presente invención se circunscribe dentro del ámbito de la construcción, y particularmente de la construcción de edificios, y de modo más preciso dentro de los balcones prefabricados.Therefore, the present invention is circumscribed within the field of construction, and particularly building construction, and more precisely within prefabricated balconies.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Las características de las viviendas que demanda el mercado van evolucionando a medida que lo hace la sociedad. La pandemia mundial de COVID19 ha reposicionado la importancia de la vivienda en la vida diaria, influenciando sin duda de forma muy determinante las preferencias de los compradores. La cuarentena y el aislamiento de la gente en sus casas ha cambiado de forma muy significativa la dinámica habitacional. En el corto plazo ya nadie duda de que la vivienda tras la pandemia debe reformularse, considerando aspectos como la salubridad que garantice un hogar seguro o la versatilidad que garantice un hogar preparado para conciliar la vida personal y laboral. Las circunstancias vividas a causa de la pandemia de COVID19 pusieron en valor aquellas viviendas con espacios abiertos como balcones o terrazas, elementos cuya construcción presentaba una tendencia a la baja debido a los cada vez más exigentes requisitos impuestos por las reglamentaciones técnicas en la edificación.The characteristics of the houses that the market demands evolve as society does. The global pandemic of COVID19 has repositioned the importance of housing in daily life, undoubtedly influencing buyers' preferences in a very decisive way. The quarantine and isolation of people in their homes has significantly changed the housing dynamics. In the short term, no one doubts that housing after the pandemic must be reformulated, considering aspects such as sanitation that guarantees a safe home or the versatility that guarantees a home prepared to reconcile personal and work life. The circumstances experienced due to the COVID19 pandemic valued those homes with open spaces such as balconies or terraces, elements whose construction showed a downward trend due to the increasingly demanding requirements imposed by technical building regulations.

Normalmente los balcones en edificios nuevos en los que sus forjados son de hormigón armado o pretensado constituyen una prolongación de los mismos en los que geométricamente se sobrepasa hacia el exterior la línea de fachada. Esta estrategia, por una parte, requiere de costosas piezas de encofrado que complican y ralentizan la construcción del edificio, y, por otra, si existe continuidad entre el balcón y el resto del forjado, puede implicar un punto de debilidad a nivel de confort térmico en el edificio, ya que se impide la continuidad del aislamiento de la envolvente exterior o fachada.Normally the balconies in new buildings in which their floors are made of reinforced or prestressed concrete constitute an extension of them in which the line of the façade is geometrically exceeded towards the outside. This strategy, on the one hand, requires expensive formwork pieces that complicate and slow down the construction of the building, and, on the other, if there is continuity between the balcony and the rest of the slab, it can imply a point of weakness in terms of thermal comfort. in the building, since the continuity of the insulation of the external envelope or façade is prevented.

El cambio de mentalidad provocado por la pandemia, unido a que desde el punto de vista urbanístico cada vez son más las comunidades que permiten la instalación de balcones, bien en proyectos de obra nueva, bien en edificios ya construidos, sin que estos elementos computen como edificabilidad, puede generar un nuevo mercado de balcones para incorporar a edificios ya ejecutados, siempre que se resuelvan esencialmente la forma de anclaje a los forjados y la manera de garantizar la continuidad de las envolventes térmicas de los edificios a los que se anclan (recordemos que prácticamente el 30% de las emisiones mundiales de CO2 provienen de la construcción y del uso de edificios, por lo que es esencial desplegar estrategias para reducir la demanda de energía del parque edificatorio).The change in mentality caused by the pandemic, together with the fact that from an urban point of view, more and more communities allow the installation of balconies, either in new construction projects or in buildings already built, without these elements counting as buildability, it can generate a new market for balconies to be incorporated into buildings that have already been completed, provided that the form of anchorage to the slabs is essentially resolved and the way to guarantee the continuity of the thermal envelopes of the buildings to which they are anchored (remember that practically 30% of global CO2 emissions come from the construction and use of buildings, so it is essential to deploy strategies to reduce the energy demand of the building stock).

Finalmente, en la actualidad no podemos dar la espalda a la política comunitaria y a todas las directrices que emanan del Pacto Verde Europeo de 2019. La Unión Europea pretende avanzar hacia un modelo de economía circular basado en productos más sostenibles y para ello, en marzo de 2022, la Comisión adoptó un paquete de medidas para hacer que los productos sostenibles sean la norma en la Unión Europea. El balcón prefabricado ligero y desmontable para incorporar a un edificio ya ejecutado que se presenta precisamente es desmontable y reutilizable, dos de las principales palancas necesarias en el ecodiseño y en facilitar la transición hacia una economía más circular.Finally, at present we cannot turn our backs on community policy and all the guidelines that emanate from the 2019 European Green Pact. The European Union intends to move towards an economic model circular based on more sustainable products and for this, in March 2022, the Commission adopted a package of measures to make sustainable products the norm in the European Union. The light and removable prefabricated balcony to be incorporated into an already completed building that is presented precisely is removable and reusable, two of the main levers needed in ecodesign and in facilitating the transition towards a more circular economy.
