Description

Sistema constructivo para la instalación de elementos divisorios de elevado aislamiento acústico.Construction system for the installation of dividing elements of high sound insulation.

Objeto de la invenciónObject of the invention

La invención concierne al sistema de construcción de elementos divisorios, o de tabiquería, cuyo objeto sea proporcionar un elevado aislamiento acústico.The invention concerns the construction system of dividing elements, or partition walls, whose object is Provide high sound insulation.

La obtención de un elevado aislamiento acústico es el resultado tanto del eficaz diseño de los elementos individuales que componen el elemento divisorio como del sistema constructivo utilizado para la ejecución del conjunto. La colocación convencional de los bloques que componen una fabrica, independientemente de las características acústicas de los mismos, supone un obstáculo para la consecución de un elevado aislamiento. Por el contrario, la colocación de los bloques siguiendo el sistema constructivo aquí propuesto, produce una importante mejora en las prestaciones acústicas del conjunto. Esta mejora puede verse reflejada en una disminución del espesor de la pared y en la imposición de condiciones menos restrictivas en las prestaciones acústicas de los bloques que componen la fabrica.Obtaining high sound insulation it is the result of both the effective design of the elements individual that make up the dividing element as the system constructive used for the execution of the set. Placement  conventional of the blocks that make up a factory, regardless of their acoustic characteristics, It is an obstacle to achieving high isolation. On the contrary, the placement of the blocks following the system constructive proposed here, produces a significant improvement in the acoustic performance of the set. This improvement can be seen reflected in a decrease in wall thickness and in the imposition of less restrictive conditions on benefits acoustics of the blocks that make up the factory.

Antecedentes Background

En numerosos estudios se proponen diversas soluciones al problema del aislamiento acústico. Las soluciones más sencillas y, por tanto, más frecuentemente utilizadas son la pared simple y la pared doble. En general, las paredes dobles presentan un mejor comportamiento que las simples excepto en la región del espacio de frecuencias donde las resonancias hacen que el comportamiento de la doble sea inferior al esperado (Manual de acústica, ruidos y vibraciones. Pedro Flores Pereita. Ediciones GYC. 1990). Para mejorar el comportamiento de la pared doble en esa región de frecuencias se adoptan diferentes tipos de soluciones, como son la eliminación de puentes sólidos entre las dos paredes, la inclusión de un material absorbente entre las mismas y que el peso de una de las paredes sea superior al de la otra.In numerous studies various solutions to the problem of sound insulation are proposed. The simplest and therefore most frequently used solutions are the single wall and the double wall. In general, the double walls have a better performance than the simple ones except in the region of the frequency space where the resonances make the behavior of the double lower than expected ( Manual of acoustics, noise and vibrations . Pedro Flores Pereita. GYC Editions . 1990). To improve the behavior of the double wall in this region of frequencies different types of solutions are adopted, such as the elimination of solid bridges between the two walls, the inclusion of an absorbent material between them and that the weight of one of the walls be superior to the other.

Estos principios se han aplicado de muy diversas formas para el desarrollo de diferentes tipos de paneles. En la bibliografía se encuentran decenas de modelos que presentan espesores, características y precios muy diversos en función del procedimiento elegido para evitar la resonancia entre la doble pared (Manual para el control del ruido. Cyril M. Harris. Instituto de Estudios de Administración Local. 1977).These principles have been applied in many different ways for the development of different types of panels. In the literature there are dozens of models that have very different thicknesses, characteristics and prices depending on the procedure chosen to avoid resonance between the double wall ( Manual for noise control . Cyril M. Harris. Institute of Local Administration Studies. 1977).

En el sistema constructivo aquí propuesto se parte de la utilización de una pared doble como elemento divisorio. Cada una de las hojas de la pared doble puede estar realizada en cualquier tipo de material (cerámico, hormigón, cartón-yeso, etc.) y en el espacio entre ellas puede disponerse, o no, material absorbente acústico.In the construction system proposed here, part of the use of a double wall as a dividing element. Each of the double wall sheets can be made in any type of material (ceramic, concrete, plasterboard, etc.) and in the space between them you can dispose, or not, acoustic absorbent material.

A continuación se describe el comportamiento de un tabique de doble pared construido con los elementos objeto de la invención con el comportamiento típico de un panel aislante.The behavior of a double wall partition built with the elements object of the invention with the typical behavior of an insulating panel.

1. Para frecuencias menores a la de resonancia los sistemas de doble pared funcionan como una pared simple con masa igual a la suma de las masas de las dos paredes que le componen.1. For frequencies lower than resonance double wall systems work like a simple wall with mass equal to the sum of the masses of the two walls that make up.

2. En la frecuencia de resonancia habrá una disminución en el aislamiento. La magnitud en la pérdida de aislamiento y su compensación dependen de muchos factores, en especial del tipo de absorbente que se coloque entre las dos capas.2. In the resonant frequency there will be a decrease in isolation The magnitude in the loss of isolation and its compensation depend on many factors, in special type of absorbent that is placed between the two layers.

3. A partir de la frecuencia de resonancia entrará en vigor la ley de masas.3. From the resonant frequency Mass law will come into force.

Además de estas frecuencias relativas a la cavidad, habrá que tener en cuenta que existe una frecuencia propia de cada pared simple.In addition to these frequencies relative to the cavity, we must bear in mind that there is a proper frequency of each simple wall.

El sistema constructivo propuesto no afecta al comportamiento del sistema a frecuencias menores que la de resonancia de la cavidad, ni a frecuencias muy superiores a la de la cavidad. Sin embargo, la desconexión que se introduce entre las paredes hace que el trasvase de energía entre ellas sea despreciable. En consecuencia, la pérdida de aislamiento es mínima tanto a la frecuencia de resonancia de la cavidad como a las frecuencias propias de cada una de las paredes.The proposed construction system does not affect the system behavior at frequencies lower than that of resonance of the cavity, even at frequencies far superior to that of The cavity. However, the disconnection that is introduced between the walls makes the transfer of energy between them negligible. Consequently, the loss of insulation is minimal both at the resonance frequency of the cavity and at the own frequencies of each of the walls.

Esto supone una importante mejora en cuanto a las prestaciones del sistema total (pared de doble hoja con o sin aislante) permitiendo obtener un elevado aislamiento acústico con un espesor de pared reducido.This is a significant improvement in terms of total system performance (double sheet wall with or without insulator) allowing to obtain a high sound insulation with a reduced wall thickness.

Descripción de la invenciónDescription of the invention

A continuación se presenta una descripción pormenorizada del sistema constructivo propuesto.Below is a description detailed of the proposed construction system.

En la figura 1 se muestra la sección de la unión entre la doble pared. Se observa como cada una de las dos hojas que componen la pared doble del elemento separador están unidas a suelo, techo y paredes a través de una banda resilente (1). Esta banda perimetral produce una desconexión entre el elemento separador y el resto de la estructura de forma que resulte imposible cualquier puente acústico. La banda resilente puede afectar al perímetro de cada fabrica o, como se muestra en la figura 2, puede ser continua y afectar a las dos fabricas simultáneamente.Figure 1 shows the section of the joint Between the double wall. It is observed as each of the two leaves that make up the double wall of the separator element are attached to floor, ceiling and walls through a resilient band (1). This perimeter band produces a disconnection between the separator element and the rest of the structure so that it is impossible any acoustic bridge The resilent band can affect the perimeter of each factory or, as shown in figure 2, you can be continuous and affect the two factories simultaneously.

Además de la desconexión debida a la banda resilente se observa tanto en la figura 1 como en la 2 que el enlucido de yeso (2), si lo hubiera, ha de interrumpirse antes de conectar la pared con las superficies limítrofes (suelo techo y paredes) produciendo un hueco (3) que sirve de desconexión. En algunas situaciones, como la descrita en la figura 3A, las paredes contiguas de una misma habitación pueden permanecer conectadas sin detrimento del aislamiento acústico total siempre que se desconecten de techo y suelo. En caso de que existan puentes acústicos (figura 3B) sería necesario la utilización de bandas resilentes en las uniones verticales además de en las
horizontales.
In addition to the disconnection due to the resilent band, it can be seen in both Figure 1 and 2 that the plaster plaster (2), if any, must be interrupted before connecting the wall with the bordering surfaces (ceiling floor and walls ) producing a gap (3) that serves as disconnection. In some situations, such as that described in Figure 3A, the adjacent walls of the same room may remain connected without detriment to the total acoustic insulation provided that they are disconnected from the ceiling and floor. If there are acoustic bridges (Figure 3B), it would be necessary to use resilent bands in the vertical joints in addition to the
horizontal.

En caso de utilizarse doble techo de escayola el montaje responde a un esquema similar (como se muestra en la figura 4) de forma que pared y techo se mantengan desconectados.If double plaster roof is used, the assembly responds to a similar scheme (as shown in the figure 4) so that wall and ceiling are kept disconnected.

Cuando se conecte la doble pared del elemento separador a un muro de fachada se han de colocar bandas resilentes como indica la figura 5 además de las bandas resilentes entre los paramentos verticales y los horizontales con el fin de producir la desconexión acústica.When the double wall of the element is connected separator to a facade wall resilent bands have to be placed as indicated in figure 5 in addition to the resilient bands between the vertical and horizontal walls in order to produce the acoustic disconnection

Descripción de las figurasDescription of the figures

Figura 1.- En la figura se observan las dos hojas de una pared doble unidas a una superficie perimetral a través de una banda resilente (1) y una masa ligante como puede ser yeso, o cemento cola. El recubrimiento de yeso (2) se ha interrumpido para formar un hueco (3). En este caso se considera que el espacio entre hojas está relleno de material aislante acústico (4).Figure 1.- The figure shows the two sheets of a double wall joined to a perimeter surface through a resilent band (1) and a binding mass such as plaster, or cement glue. The plaster coating (2) has been interrupted to form a hole (3). In this case it is considered that the space between sheets is filled with acoustic insulating material (4).

Figura 2.- El montaje es similar a la figura 1 aunque la banda resilente ahora es continua ocupa la superficie de contacto de la pared doble con la superficie perimetral.Figure 2.- The assembly is similar to figure 1 although the resilent band is now continuous occupies the surface of double wall contact with the perimeter surface.

Figura 3.- Se observa que en la unión vertical de paramentos pertenecientes a una misma habitación no es necesario interrumpir el recubrimiento (3A), aunque sigue siendo imprescindible la interrupción en la unión con techo y paredes. Cuando existen puentes acústicos (3B) el uso de banda resilente en la unión vertical es imprescindible.Figure 3.- It is observed that in the vertical union of walls belonging to the same room is not necessary interrupt the coating (3A), although it remains essential the interruption in the union with ceiling and walls. When there are acoustic bridges (3B) the use of resilent band in Vertical union is essential.

Figura 4.- En el caso de una habitación con doble techo la desconexión ha de producirse como se muestra en la figura, de forma que el doble techo no esté en contacto con el recubrimiento de yeso de la pared.Figure 4.- In the case of a double room ceiling disconnection must occur as shown in the figure, so that the double roof is not in contact with the plaster wall covering.

Figura 5.- En el caso de un elemento divisorio conectado a una pared de fachada la conexión ha de realizarse a través de una banda resilente. La pared de fachada se puede completar con una doble pared y disponer en el espacio intermedio un material aislante como indica la figura.Figure 5.- In the case of a dividing element connected to a facade wall the connection must be made to through a resilent band. The facade wall can be complete with a double wall and arrange in the intermediate space an insulating material as indicated in the figure.

Un modo de realización de la invenciónAn embodiment of the invention

A continuación se detalla una posible realización del elemento divisorio de alto aislamiento acústico.A possible embodiment is detailed below. of the dividing element of high acoustic insulation.

El elemento divisorio propuesto consta de tres capas, las dos externas son cerámicas y la intermedia de lana de roca según muestra la figura 1. Es necesario hacer constar que el sistema constructivo puede aplicarse independientemente de la naturaleza de las capas externas que pueden ser cerámicas, de hormigón o de cartón-yeso. De la misma forma, la capa intermedia puede ser de aire, o de cualquier material de naturaleza aislante.The proposed dividing element consists of three layers, the two outer ones are ceramic and the wool intermediate of rock as shown in figure 1. It is necessary to state that the constructive system can be applied independently of the nature of the outer layers that can be ceramic, of concrete or plasterboard. In the same way, the intermediate layer can be of air, or of any material of insulating nature.

Las dos capas externas están unidas a las superficies perimetrales a través de una banda resilente. La banda puede ser continua o afectar únicamente a cada una de las dos fabricas por separado (figura 2).The two outer layers are attached to the perimeter surfaces through a resilient band. The band it can be continuous or affect only each of the two factories separately (figure 2).

En la figura 3A se observa que, cuando no existe puente acústico entre habitaciones contiguas (por ejemplo columnas), es suficiente la desconexión entre el paramento vertical (elemento separador) y los horizontales (suelo y techo). Esto simplifica el montaje ya que la banda resilente se colocaría únicamente en suelo y techo. Sin embargo la existencia de columnas (figura 3B) hace necesario el uso de banda resilente en las uniones verticales.Figure 3A shows that, when it does not exist acoustic bridge between adjoining rooms (for example columns), the disconnection between the vertical wall is sufficient (separating element) and horizontal (floor and ceiling). This simplifies assembly since the resilent band would be placed only on floor and ceiling. However the existence of columns (Figure 3B) makes it necessary to use resilent band in the joints vertical

En todos los casos en los que exista un recubrimiento, es condición indispensable que este se interrumpa al llegar a la banda resilente. Si hubiese un falso techo (figura 4) la interrupción tendría que producirse antes de forma que no hubiese contacto entre recubrimiento y falso techo.In all cases where there is a coating, it is an indispensable condition that this be interrupted by Get to the resilent band. If there were a false ceiling (figure 4) the interruption would have to occur before so that no there would be contact between cover and false ceiling.
