Description

Prelosa para forjados.Pre-slab for floors.

Sector de la técnicaTechnical sector

La presente invención está relacionada con la construcción de los forjados de división entre los espacios de diferentes alturas y de formación de la cubierta superior, en las edificaciones, proponiendo una prelosa que permite construir dichos forjados en unas condiciones y con una realización muy ventajosas.The present invention is related to the construction of the floor slabs between the spaces of different heights and upper deck formation, in the buildings, proposing a pre-slab that allows building said forged in conditions and with a very realization advantageous

Estado de la técnicaState of the art

Las estructuras de las edificaciones se forman convencionalmente con un armazón de columnas y vigas, sobre el cual se determina la cubierta superior y las divisiones entre los espacios de diferentes alturas, con unas estructuras denominadas forjados.Building structures are formed conventionally with a frame of columns and beams, on which the upper deck and the divisions between the spaces of different heights, with structures called forged

Según una realización habitual, las estructuras de dichos forjados se forman disponiendo una serie de viguetas paralelas de hormigón pretensado, las cuales se apoyan por sus extremos sobre la vigas del armazón estructural de la construcción, incorporándose sobre las viguetas unos elementos denominados bovedillas, que pueden ser cerámicas o de hormigón, determinando con el conjunto de las bovedillas una superficie cerrada, sobre la cual se echa una capa de hormigón, denominada capa de compresión, mediante la cual se unifica el conjunto estructural constituyendo una placa resistente.According to a usual embodiment, the structures of these slabs are formed by arranging a series of joists parallel of prestressed concrete, which are supported by their ends on the beams of the structural framework of the construction, incorporating elements called on the joists vaults, which can be ceramic or concrete, determining with the set of the vaults a closed surface, on which a layer of concrete, called a compression layer, is cast, by which the structural set is unified constituting a sturdy plate

El montaje de esos forjados se realiza totalmente en obra, disponiendo primero las viguetas sobre las vigas del armazón estructural de la edificación y luego las bovedillas sobre las viguetas, lo cual requiere una labor lenta y costosa, teniendo que deambular los operarios montadores por encima de los elementos que van quedando montados, es decir sobre las viguetas y las bovedillas, conllevando esto un grave riesgo de accidentes, ya que las bovedillas son frágiles y pueden romperse al pisar sobre ellas.The assembly of these slabs is done fully under construction, first placing the joists on the beams of the structural framework of the building and then the vaults on the joists, which requires slow and expensive labor, having to roam the assembly workers above the elements that remain mounted, that is to say on the joists and the vaults, leading to a serious risk of accidents, since that the vaults are fragile and can be broken by stepping on they.

Como alternativa se han desarrollado soluciones de construcción de los forjados con losas prefabricadas de hormigón pretensado, las cuales se disponen sucesivamente una al lado de otra, apoyándolas sobre las vigas del armazón estructural de la construcción, con lo cual se reduce el tiempo del montaje de la construcción y se elimina el riesgo de accidentes, ya que no hay que deambular sobre elementos frágiles como son las bovedillas.As an alternative, solutions have been developed construction of the slabs with precast concrete slabs prestressed, which are arranged successively next to another, supporting them on the beams of the structural framework of the construction, which reduces the assembly time of the construction and the risk of accidents is eliminated, since there is no need to wander around fragile elements such as vaults.

Sin embargo, con las losas prefabricadas que se utilizan en las soluciones conocidas de este tipo, surge un problema por la incomodidad de realizar instalaciones de conducciones en su cara inferior ante la imposibilidad de poder rozar el hormigón de la losa prefabricada, y además es necesario complementar los forjados con capas aislantes para cumplir con las exigencias a las que obligan actualmente las normas de la construcción, con lo cual las construcciones siguen siendo lentas y costosas.However, with the prefabricated slabs that used in known solutions of this type, a problem arises for the inconvenience of conducting conduction facilities in your inferior face before the impossibility of being able to touch the concrete of the prefabricated slab, and it is also necessary to complement the slabs with insulating layers to meet the requirements to which currently obey the construction standards, which constructions are still slow and expensive.

Objeto de la invenciónObject of the invention

De acuerdo con la invención se propone una prelosa destinada para la formación de los forjados en las edificaciones, la cual se ha desarrollado con unas características estructurales que la hacen funcionalmente ventajosa para la construcción de los forjados de aplicación.According to the invention, a pre-slab intended for the formation of the slabs in the buildings, which has been developed with characteristics structural that make it functionally advantageous for the construction of application slabs.

Esta prelosa objeto de la invención consta de un cuerpo base moldeado de hormigón armado y/o pretensado, el cual determina una placa base continua de una dimensión determinada, saliendo de dicha placa en la cara superior unas conformaciones del mismo material constructivo a modo de nervios longitudinales, mientras que sobre la cara inferior incorpora solidariamente unida una capa hormigón aligerado con arcilla expandida.This prelosa object of the invention consists of a molded base body of reinforced and / or prestressed concrete, which determines a continuous base plate of a given dimension, out of said plate in the upper face some conformations of the same constructive material as longitudinal ribs, while on the lower face incorporates jointly united a concrete layer lightened with expanded clay.

Se obtiene de este modo una prelosa de gran resistencia a los esfuerzos perpendiculares sobre ella, de modo que puede disponerse apoyada sobre las vigas del armazón estructural de las edificaciones, para formar, mediante la colocación de sucesivas prelosas consecutivas, una superficie cerrada, sobre la cual pueden disponerse armaduras metálicas entre los nervios de la cara superior de las prelosas, para echar sobre todo el conjunto un cubrimiento de hormigón en funciones de capa de compresión.In this way a large pre-slab is obtained resistance to perpendicular efforts on it, so that it can be placed on the beams of the structural framework of the buildings, to form, by placing successive consecutive pre-slabs, a closed surface, on which they can metal armor be arranged between the nerves of the upper face of the pre-slabs, to cover the whole with a covering of concrete in compression layer functions.

De este modo se pueden construir forjados de una manera sencilla y rápida, sin tener que pisar sobre elementos frágiles con riesgo de accidentes, pero además los forjados se obtienen con una capa de superficie en la cara inferior que confiere cualidades de aislamiento térmico, acústico y contra la propagación de incendios, de forma que mediante la colocación de las prelosas y la formación de la capa de compresión sobre ellas, se obtiene el forjado totalmente terminado, sin tener que realizar posteriormente incorporaciones complementarias de aislamiento.In this way you can build slabs of a simple and fast way, without having to step on elements fragile with risk of accidents, but also the floors are they get with a surface layer on the underside that confers qualities of thermal, acoustic and propagation insulation of fires, so that by placing the pre-slabs and the formation of the compression layer on them, you get the forged completely finished, without having to perform later complementary insulation incorporations.

De igual manera la capa inferior de la prelosa es susceptible de ser rozada y facilitar de este modo la instalación de conducciones eléctricas o de otro tipo, evitando la incomodidad de realizar este tipo de instalaciones directamente sobre el hormigón de la parte superior de la prelosa mucho más duro.Similarly the lower layer of the pre-slab It is likely to be brushed and thus facilitate installation of electrical or other conduits, avoiding discomfort of performing this type of installation directly on the concrete from the top of the pre-slab much harder.

Por todo ello, dicha prelosa objeto de la invención resulta de unas características ciertamente ventajosas, adquiriendo vida propia y carácter preferente para la función de construcción de forjados a la que se halla destinada.Therefore, said prelosa object of the invention results from certainly advantageous features, acquiring own life and preferential character for the function of construction of slabs to which it is intended.
