Abstract

The false ceiling consists of reinforced concrete slabs (1) with fixings (3, 4), mounted on fastening members (5) fixed to a secondary frame (2). The fixings, made e.g. in the form of threaded rods, can be attached to reinforcing elements inside the concrete slabs, which have flexible joints between adjacent edges. The upper surfaces of the slabs are covered by at least one layer (7, 8) of a thermal insulation material and ribbed metal sheets (6), while their lower surfaces have a finishing layer (14).

Description

Falso techo suspendido.Suspended suspended ceiling.

La presente invención tiene por objeto un falso techo destinado en particular a ser aplicado en los edificios industriales tales como fábricas (véase por ejemplo el documento FR 550 722 A).The present invention aims at a false roof intended in particular to be applied in buildings industrials such as factories (see for example FR document 550 722 A).

Uno de los problemas que plantea la realización de falsos techos es el de asegurar una protección eficaz contra el fuego.One of the problems posed by the realization of false ceilings is to ensure effective protection against fire.

En efecto, los falsos techos son vectores privilegiados de propagación de los incendios en los locales industriales.Indeed, suspended ceilings are vectors privileged spread of fires in the premises Industrial

Uno de los objetos de la invención es un falso techo que por su naturaleza asegure una protección completa contra los incendios.One of the objects of the invention is a false roof that by its nature ensures complete protection against the fires.

Otra finalidad de la invención es un falso techo que asegure un aislamiento térmico.Another purpose of the invention is a false ceiling To ensure thermal insulation.

Otro objeto de la invención es un falso techo que sea sencillo de ensamblar.Another object of the invention is a false ceiling that Be easy to assemble.

Por lo menos uno de los objetos citados se logra con un falso techo que comprenda placas o losas provistas de elementos de fijación montados sobre piezas de fijación solidarias de un elemento de armazón secundario, que sirva de soporte al falso techo.At least one of the objects mentioned is achieved with a false ceiling comprising plates or slabs provided with fixing elements mounted on solidarity fixing parts of a secondary frame element, which supports the false ceiling.

Las placas son ventajosamente de hormigón armado. Los elementos de fijación, por ejemplo varillas fileteadas, pueden ser montados sobre unos elementos complementarios, por ejemplo unos manguitos, solidarios de la armadura de la placa. Estos elementos complementarios están por ejemplo atravesados por un hierro para hormigón fijado sobre dicha armadura de la placa.The plates are advantageously reinforced concrete. The fasteners, for example threaded rods, can be mounted on complementary elements, for example ones sleeves, solidary of the plate armor. This elements complementary are for example crossed by an iron to concrete fixed on said plate reinforcement.

Se pueden interponer unas juntas flexibles entre bordes adyacentes de las placas.Flexible joints can be interposed between adjacent edges of the plates.

Puede obtenerse un aislamiento térmico disponiendo sobre las placas por lo menos una capa de material térmicamente aislante.Thermal insulation can be obtained arranging at least one layer of material on the plates thermally insulating.

En su parte superior, el falso techo puede quedar cubierto por unas chapas nervadas montadas sobre las piezas de fijación mediante unos elementos de fijación de las placas.In its upper part, the false ceiling can remain covered by ribbed plates mounted on the pieces of fixing by means of fixing elements of the plates.

La cara inferior de las placas puede estar revestida con una capa de acabado por ejemplo de resina poliéster.The underside of the plates may be coated with a topcoat for example resin polyester.

Aparecerán más claramente otras características y ventajas de la invención en la lectura de la descripción dada a continuación a titulo no limitativo, en conexión con los dibujos adjuntos, en los cuales:Other features will appear more clearly and advantages of the invention in reading the description given to then non-limiting title, in connection with the drawings attachments, in which:

-la figura 1 representa una vista en corte y en perspectiva de una forma de realización preferida de la invención;-Figure 1 represents a view in section and in perspective of a preferred embodiment of the invention;

-la figura 2 representa un corte transversal del dispositivo de la figura 1.-Figure 2 represents a cross-section of the device of figure 1.

El falso techo según la invención comprende un conjunto de placas 1 hechas con material no combustible, y en particular de hormigón armado, de un espesor generalmente comprendido entre 5 y 7 cm según el vano que se trate de cubrir, el cual será en general de 5 a 6 m.The suspended ceiling according to the invention comprises a set of plates 1 made with non-combustible material, and in particular reinforced concrete, generally thick between 5 and 7 cm depending on the span in question, the which will be in general from 5 to 6 m.

En estas placas 1, quedan situados antes del vaciado unos manguitos 9, por ejemplo de acero inoxidable, atravesados en su base por una varilla de acero 10 ("hierro para hormigón") fijada sobre el armazón de estructura (o armadura) de la placa 1, esto con el fin de impedir todo posible arrancamiento del manguito después de haber fraguado el hormigón.In these plates 1, they are located before the emptying sleeves 9, for example stainless steel, pierced at its base by a steel rod 10 ("iron for concrete ") fixed on the frame structure (or reinforcement) of plate 1, this in order to prevent any possible tearing of the sleeve after setting the concrete.

Estos manguitos 9 sirven para recibir varillas fileteadas 3 (por ejemplo de 12 mm de diámetro) destinadas a ser enganchadas en el armazón secundario mediante unos pernos 4 que permitan a un tiempo fijar las varillas y regular el nivel de las placas delgadas 1.These sleeves 9 serve to receive rods filleted 3 (for example 12 mm in diameter) intended to be hooked on the secondary frame by bolts 4 that allow at the same time to fix the rods and regulate the level of the thin plates 1.

El enganche se realiza de la manera siguiente. Se fijan unas platinas metálicas 5 en la parte inferior de unos elementos 2 de armazón secundario, por ejemplo vigas metálicas, como se ha representado, que serán solidarias de un armazón metálico principal 20. Estas platinas metálicas 5 están atravesadas por las varillas 3, y los pernos 4 se enroscan para igualmente fijar unas chapas nervadas 6 por ejemplo de aluminio, formando un encofrado colaborador que cubrirá el falso techo. En sentido longitudinal, las chapas 6 se montan juntas utilizándose remaches o roblones, para asegurar la sujeción deseada.The hitch is done as follows. Be fix some metal plates 5 at the bottom of some secondary frame elements 2, for example metal beams, such as has been represented, who will be in solidarity with a metal framework main 20. These metal plates 5 are crossed by the rods 3, and bolts 4 are threaded to also fix some ribbed sheets 6 for example of aluminum, forming a formwork collaborator that will cover the false ceiling. Longitudinally, the plates 6 are mounted together using rivets or roblones, to ensure the desired support.

Por encima de las placas, se colocan dos capas cruzadas 7 y 8 de lana de vidrio de por ejemplo 50 mm de espesor cada uno.Above the plates, two layers are placed crossed 7 and 8 of glass wool, for example 50 mm thick each.

El conjunto es capaz de sustentar una sobrecarga de 100 kg/m^{2}, es decir, el peso de una persona de la obra con una caja de herramientas.The set is capable of sustaining an overload of 100 kg / m2, that is, the weight of a work person with a toolbox

Las placas 1 presentan unos bordes en bisel 12 cuya parte inferior está equipada con unas juntas elásticas 11 que permiten asegurar la continuidad de un revestimiento de acabado 14 (por ejemplo de resina de poliéster) de la cara inferior de las placas 1. La unión entre las placas 1 se realiza preferentemente en la vertical de las vigas 3 entre dos hileras de fijación (3, 4, 9).The plates 1 have bevel edges 12 whose bottom is equipped with elastic joints 11 that allow to ensure the continuity of a finishing coating 14 (for example polyester resin) of the underside of the plates 1. The connection between plates 1 is preferably carried out in the vertical of the beams 3 between two fixing rows (3, 4, 9).
