Dispositivo para medir el espesor de acristalamientos Objeto de la invencionDevice for measuring the thickness of glazing Object of the invention
La presente invencion se refiere a un dispositivo para medir el espesor de acristalamiento que permite medir el espesor de acristalamientos instalados en carpinterias, independientemente de las capas que dicho acristalamiento comprenda, y sin necesidad de que el acristalamiento tenga que ser desmontado para realizar la medicion de su espesor. Es decir, la invencion puede ser utilizada tanto en el caso de vidrios simples como en el caso de vidrios compuestos, permitiendo medir incluso el espesor de las camaras de aislamiento intermedias, formadas con aire o liquido. La invencion tiene aplicacion en la industria de la edificacion, y mas concretamente en el ambito de la peritacion de acristalamientos en edificios.The present invention relates to a device for measuring the thickness of glazing that allows to measure the thickness of glazing installed in carpentry, regardless of the layers that said glazing comprises, and without the need for the glazing to be disassembled to measure its thickness That is, the invention can be used both in the case of simple glasses and in the case of composite glasses, allowing even the thickness of the intermediate insulation chambers, formed with air or liquid, to be measured. The invention has application in the building industry, and more specifically in the field of glazing in buildings.
Antecedentes de la invencionBackground of the invention
En la actualidad, con motivo de conseguir una mayor eficiencia energetica, el conocer el poder aislante de los materiales de la envolvente de un edificio cobra una gran importancia. Una de las partes de esta envolvente donde se produce una mayor transmision de energia (ganancias calorificas en climas calidos y perdidas en climas frios) es la parte acristalada de los mismos (tanto de fachadas como de cubiertas). De ah la importancia de conseguir acristalamientos con un alto poder aislante termico y acustico. Para ello, es importante intentar minimizar lo maximo posible la transmitancia de los mismos.At present, in order to achieve greater energy efficiency, knowing the insulating power of the building envelope materials is of great importance. One of the parts of this envelope where there is a greater transmission of energy (calorific gains in hot climates and lost in cold climates) is the glazed part of them (both facades and roofs). Hence the importance of achieving glazing with a high thermal and acoustic insulating power. For this, it is important to try to minimize their transmittance as much as possible.
Actualmente, los acristalamientos mas eficientes, desde el punto de vista termico y acustico, se componen de varias capas en lugar de un vidrio simple como se hada antiguamente. Habitualmente, estas capas estan formadas por uno o mas vidrios en la cara exterior del acristalamiento, una camara (de un liquido o un gas), y una ultima capa compuesta a su vez por uno o varios vidrios. En algunos casos, se puede llegar a incorporar varias camaras en un mismo acristalamiento si los requisitos tecnicos lo demandan. En funcion del espesor de cada uno de los vidrios y de las camaras que componen el acristalamiento, la transmitancia del mismo variara.Currently, the most efficient glazing, from the thermal and acoustic point of view, is made up of several layers instead of a simple glass as it was once. Usually, these layers are formed by one or more glasses on the outer face of the glazing, a chamber (of a liquid or a gas), and a last layer composed of one or more glasses. In some cases, several cameras can be incorporated in the same glazing if the technical requirements demand it. Depending on the thickness of each of the glasses and the chambers that make up the glazing, the transmittance thereof will vary.
Mientras que es muy facil medir el espesor de un vidrio o de una camara antes de montarlo, este proceso se complica al tener el acristalamiento montado en una carpinteria. Sin embargo, en una obra ya construida o de rehabilitation lo normal es que los acristalamientos ya esten montados en las carpinterias. Ademas, cualquier vivienda que vaya a ser alquilada,While it is very easy to measure the thickness of a glass or a camera before mounting it, this process is complicated by having the glazing mounted on a carpentry. However, in a work already built or rehabilitation, the normal thing is that the glazing is already mounted in the carpentry. In addition, any home that will be rented,

debe tener un certificado de eficiencia energetica. Para poder realizarlo, es necesario entre otras cosas, conocer los espesores de los acristalamientos. Por consiguiente, conocer el espesor de cada uno de los integrantes del acristalamiento sera necesario para poder conocer la transmitancia de los mismos y asi poder evaluar el flujo de transmision de energia (frio o calor).You must have a certificate of energy efficiency. To be able to do it, it is necessary, among other things, to know the thicknesses of the glazing. Therefore, knowing the thickness of each of the members of the glazing will be necessary to be able to know their transmittance and thus be able to evaluate the flow of energy transmission (cold or heat).
Actualmente, para definir la composition de un acristalamiento montado en una carpinteria, era necesario desmontar el mismo, eliminando el sellado existente entre el acristalamiento y la carpinteria, medir el espesor de cada una de las capas y, finalmente, volver a montar el acristalamiento en la carpinteria, sellando ambos elementos.Currently, to define the composition of a glazing mounted on a carpentry, it was necessary to disassemble it, eliminating the seal between the glazing and the carpentry, measure the thickness of each of the layers and finally reassemble the glazing in the carpentry, sealing both elements.
Existen numerosos dispositivos para medir el espesor de un acristalamiento sin estar montado en una carpinteria. Sin embargo, no existe un dispositivo que permita hacerlo con el acristalamiento montado en la propia carpinteria, lo que evitaria tener que desmontar el mismo, con el consiguiente riesgo de rotura en dicho proceso. Ademas, en edificios que tengan protection especial (edificios historicos) el desmontaje de vidrios suele estar prohibido.There are numerous devices for measuring the thickness of a glazing without being mounted in a carpentry. However, there is no device to do so with the glazing mounted on the carpentry itself, which would avoid having to disassemble it, with the consequent risk of breakage in said process. In addition, in buildings that have special protection (historic buildings) the disassembly of glass is usually prohibited.
Description de la inventionDescription of the invention
La presente invencion se refiere a un dispositivo para medir el espesor de acristalamientos, permitiendo hacerlo en los acristalamientos de puertas y ventanas formados por capas de vidrios, con o sin capas aislantes intermedias de aire y/o liquido, todo ello mediante un dispositivo que ocupa un espacio reducido, puede ser transportado con facilidad, tiene un coste bajo y puede ser utilizado de manera rapida y sin sencilla, y lo mas destacable, sin necesidad de desmontar el acristalamiento de la carpinteria en la que se encuentra montado o instalado en un edificio.The present invention relates to a device for measuring the thickness of glazing, allowing it to be done in the glazing of doors and windows formed by layers of glass, with or without intermediate insulating layers of air and / or liquid, all through a device that occupies a small space, can be transported easily, has a low cost and can be used quickly and easily, and most notably, without the need to disassemble the glazing of the carpentry in which it is mounted or installed in a building .
El objeto de la invencion se consigue con un dispositivo tal y como se define en la revindication 1. En reivindicaciones dependientes se definen realizaciones particularmente ventajosas de la invencion.The object of the invention is achieved with a device as defined in revindication 1. Particularly advantageous embodiments of the invention are defined in dependent claims.
De acuerdo con la invencion, el dispositivo para medir el espesor de acristalamientos consiste en una escuadra articulada.According to the invention, the device for measuring the thickness of glazing consists of an articulated square.
Uno de los lados de la escuadra articulada es el elemento de fijacion que puede quedar situado sobre un acristalamiento.One of the sides of the articulated square is the fixing element that can be placed on a glazing.

Otro de los lados de la escuadra articulada sirve de soporte a una escala graduada, de manera que en una posicion de uso, el soporte de escala graduada forma un angulo de 90° respecto al elemento de fijacion.Another of the sides of the articulated square serves as a support on a graduated scale, so that in a position of use, the graduated scale support forms an angle of 90 ° with respect to the fixing element.
Asimismo, el dispositivo comprende un emisor de haz laser situado en un soporte de haz laser que esta vinculado al elemento de fijacion de manera que en la posicion de uso forma 45° respecto del elemento de fijacion. De este modo, una proyeccion de haz laser sobre el acristalamiento es reflejada en la escala graduada permitiendo determinar el espesor de dicho acristalamiento.Also, the device comprises a laser beam emitter located in a laser beam holder that is linked to the fixing element so that in the use position it forms 45 ° with respect to the fixing element. Thus, a laser beam projection on the glazing is reflected in the graduated scale allowing the thickness of said glazing to be determined.
Por lo tanto, el dispositivo esta basado en la reflexion de un haz laser sobre la superficie del vidrio. El rayo, al proyectarse sobre el acristalamiento, produce un reflejo en el lado horizontal de la escuadra con las medidas de los vidrios y la camara. Este elemento horizontal cuenta con una escala graduada, adecuada y en correspondencia con los espesores de cristal, para facilitar la determination del espesor en funcion de dicho reflejo. Esta calibration puede realizarse previamente con acristalamientos, como comprobacion.Therefore, the device is based on the reflection of a laser beam on the glass surface. The beam, when projected on the glazing, produces a reflection on the horizontal side of the square with the measurements of the glass and the camera. This horizontal element has a graduated scale, suitable and in correspondence with the glass thicknesses, to facilitate the determination of the thickness depending on said reflection. This calibration can be done previously with glazing, as a check.
Se contempla la posibilidad de que el elemento de fijacion este vinculado al soporte de escala graduada mediante una articulation, por ejemplo una rotula, que permite, en la posicion de uso, que el soporte de escala graduada forme un angulo maximo de 90° respecto al elemento de fijacion. Asi es mas facilmente transportable cuando no se encuentra en la posicion de uso, pues resulta como una escuadra articulada que puede ser plegada para su transporte a obra, cabiendo incluso en el maletero de un vehiculo automovil.It is contemplated that the fixing element is linked to the graduated scale support by means of an articulation, for example a label, which allows, in the use position, that the graduated scale support forms a maximum angle of 90 ° with respect to the fixing element. Thus it is more easily transportable when it is not in the position of use, as it results as an articulated square that can be folded for transport to work, even fitting in the trunk of a car.
En este sentido, tambien se contempla que el soporte del haz laser este vinculado al elemento de fijacion mediante una segunda articulacion, por ejemplo una rotula, de manera que en la posicion de uso el angulo maximo de 45° respecto al elemento de fijacion esta definido por una pieza de tope de giro, que puede estar situada tanto en el elemento de fijacion como en el soporte del haz laser.In this sense, it is also contemplated that the support of the laser beam is linked to the fixing element by means of a second joint, for example a label, so that in the position of use the maximum angle of 45 ° with respect to the fixing element is defined by a turn stop piece, which can be located both in the fixing element and in the support of the laser beam.
Por otra parte, con el objeto de que un operario no tenga que estar sujetando el dispositivo en la posicion de uso, se contempla que el dispositivo comprenda medios de fijacion del elemento de fijacion al acristalamiento, los cuales pueden consistir en una ventosa que se fija al acristalamiento.On the other hand, in order that an operator does not have to be holding the device in the use position, it is contemplated that the device comprises means for fixing the fixing element to the glazing, which may consist of a suction cup that is fixed to the glazing.

Por otra parte, para asegurar una disposition correcta del dispositivo en la position de uso, conviene disponer de medios que aseguren la verticalidad del elemento de fijacion al acristalamiento. En este sentido se contempla que el elemento de fijacion comprenda un nivel de verticalidad, por ejemplo de burbuja.On the other hand, to ensure a correct disposition of the device in the position of use, it is convenient to have means that ensure the verticality of the fixing element to the glazing. In this sense it is contemplated that the fixing element comprises a level of verticality, for example of bubble.
En este sentido, para la solution que comprende la articulation, se contempla que el soporte de escala graduada comprenda un nivel de horizontalidad, para asegurar su posicion a 90°, la cual puede no obtenerse en caso de que la articulacion no se haya abierto completamente hasta su posicion maxima, o en el caso de que esta haya cedido como consecuencia del uso.In this sense, for the solution comprising the articulation, it is contemplated that the graduated scale support comprises a level of horizontality, to ensure its position at 90 °, which may not be obtained in case the joint has not opened completely up to its maximum position, or in the case that it has yielded as a result of the use.

Descripcion detallada de la invencionDetailed description of the invention
A la vista de las figuras resenadas puede observarse como en una de las posibles realizaciones de la invencion el dispositivo que la invencion propone comprende tres partes: un elemento de fijacion (1) al acristalamiento (7), un soporte (2) de escala graduada y un soporte del haz laser (3).In view of the figures summarized, it can be observed that in one of the possible embodiments of the invention the device proposed by the invention comprises three parts: a fixing element (1) to the glazing (7), a support (2) of graduated scale and a laser beam support (3).
El elemento de fijacion (1) tiene como mision unir el dispositivo al acristalamiento (7) que se quiera medir su espesor. Para ello, lleva incorporado medios de fijacion que consisten en una ventosa (4) que permite, mediante una pequena presion, que quede fijado alThe fixing element (1) has the mission of attaching the device to the glazing (7) that wants to measure its thickness. For this, it incorporates fixing means consisting of a suction cup (4) that allows, through a small pressure, to be fixed to the

acristalamiento (7). El elemento de fijacion (1) dispone de un nivel de verticalidad (5) de burbuja que garantiza la colocacion del elemento de fijacion (1) en posicion vertical. Ademas, el elemento de fijacion (1) tiene dos tacos (8) con sendos tornillos de regulation (9) que permiten mediante su giro alejar o acercar la parte inferior del elemento de fijacion (1) hasta colocar este paralelo a la cara del acristalamiento (7) segun el nivel de verticalidad (5). De esta forma, al tener el dispositivo tres puntos de apoyo con el acristalamiento (7): la ventosa (4) y los dos tacos (8), se asegura que este quede totalmente en contacto y no balancee.glazing (7). The fixing element (1) has a level of verticality (5) of bubble that guarantees the placement of the fixing element (1) in vertical position. In addition, the fixing element (1) has two dowels (8) with two adjustment screws (9) that allow by turning it away or near the lower part of the fixing element (1) until it is placed parallel to the face of the glazing (7) according to the level of verticality (5). In this way, when the device has three points of support with the glazing (7): the suction cup (4) and the two blocks (8), it is ensured that it is fully in contact and does not swing.
El soporte (2) de escala graduada tiene como mision recoger la proyeccion del haz laser (11) reflejado por el acristalamiento (7) sobre la escala graduada (14). Esta escala graduada (14) puede cambiarse por otra en funcion de las necesidades particulares. Con objeto de garantizar la horizontalidad del soporte (2) de escala graduada, se ha incorporado un nivel de horizontalidad (15). Ademas, para evitar ser golpeado al plegarse el soporte (2) de escala graduada con el elemento de fijacion (1) al acristalamiento (7), existe una pieza de tope de cierre (16).The support (2) of graduated scale is intended to collect the projection of the laser beam (11) reflected by the glazing (7) on the graduated scale (14). This graduated scale (14) can be changed to another depending on the particular needs. In order to guarantee the horizontality of the support (2) of graduated scale, a level of horizontality (15) has been incorporated. Furthermore, in order to avoid being hit when the graded scale support (2) is folded with the fixing element (1) to the glazing (7), there is a closing stop piece (16).
El soporte del haz laser (3) fija dicho haz (11) y lo mantiene en un direction y con una inclination determinadas. Para su fijacion el haz laser (11) se inserta sobre un carril (12) que existe en el soporte del haz laser (3) y permite su desplazamiento sin modificar su direccion. Ademas, el soporte del haz laser (3) tiene una pieza de tope de giro (13) que permite que el soporte del haz laser (3) forme un determinado angulo, de 45°, con el elemento de fijacion (1).The laser beam support (3) fixes said beam (11) and maintains it in a certain direction and inclination. For its fixation the laser beam (11) is inserted on a rail (12) that exists in the support of the laser beam (3) and allows its displacement without changing its direction. In addition, the laser beam support (3) has a turn stop piece (13) that allows the laser beam holder (3) to form a certain angle, 45 °, with the fixing element (1).
La union del elemento de fijacion (1) con el soporte (2) de escala graduada se realiza mediante una articulation (10), que puede ser una rotula, que permite plegar el soporte (2) de escala graduada sobre el elemento de fijacion (1) reduciendo el tamano del dispositivo y facilitando su transporte.The union of the fixing element (1) with the support (2) of graduated scale is carried out by means of an articulation (10), which can be a label, which allows the support (2) of graduated scale to be folded onto the fixing element ( 1) reducing the size of the device and facilitating its transport.
La union del elemento de fijacion (1) con el soporte del haz laser (3) se soluciona con una segunda articulacion (6), que igualmente puede ser una rotula (6), que permite, al girar una pieza sobre la otra, que el soporte del haz laser (3) entre y se escamotee en un hueco que tiene el elemento de fijacion (1), reduciendo su tamano y facilitando su transporte. Este giro queda impedido cuando el soporte del haz laser (3) forma un angulo de 45° con el elemento de fijacion (1), gracias a la pieza de tope de giro (13).The union of the fixing element (1) with the support of the laser beam (3) is solved with a second joint (6), which can also be a label (6), which allows, when rotating a piece on the other, that the support of the laser beam (3) enters and is retracted in a recess that has the fixing element (1), reducing its size and facilitating its transport. This rotation is impeded when the laser beam support (3) forms an angle of 45 ° with the fixing element (1), thanks to the rotation stop part (13).
El procedimiento para la medicion del espesor del acristalamiento (7) consiste en desplegar el soporte (2) de escala graduada del elemento de fijacion (1). Girar el soporte del haz laserThe procedure for measuring the thickness of the glazing (7) consists in deploying the support (2) of graduated scale of the fixing element (1). Rotate the laser beam holder

(4) , el dispositivo al acristalamiento (7). Colocar el dispositivo en posicion vertical mediante el nivel de verticalidad (5) y paralelo al acristalamiento (7) mediante el giro de los tornillos de regulacion (9). De esta forma el dispositivo queda en contacto con el acristalamiento (7) a traves de la ventosa (4) y de los tacos (8). Comprobar que el soporte (2) de escala graduada se encuentra nivelado mediante el nivel de horizontalidad (15). Activar el haz laser (11) y moverlo a traves del carril (12) hasta la posicion deseada. Observar las proyecciones sobre la escala graduada (14) del haz laser debido a la reflexion del mismo al incidir sobre el acristalamiento (7). Las diferentes marcas de esta proyeccion senalan el inicio y final de cada vidrio o camara. Como aparecen sobre la escala graduada (14) es sencillo obtener el espesor de cada uno de los componentes de ese acristalamiento (7).(4), the device to the glazing (7). Place the device in a vertical position using the vertical level (5) and parallel to the glazing (7) by turning the adjustment screws (9). In this way the device is in contact with the glazing (7) through the suction cup (4) and the plugs (8). Check that the graduated scale support (2) is level with the horizontal level (15). Activate the laser beam (11) and move it through the rail (12) to the desired position. Observe the projections on the graduated scale (14) of the laser beam due to the reflection of the laser beam when affecting the glazing (7). The different brands of this projection mark the beginning and end of each glass or camera. As they appear on the graduated scale (14) it is simple to obtain the thickness of each of the components of that glazing (7).
Obviamente, el dispositivo puede estar compuesto de cualquier material, ya sea plastico, madera, metal o cualquier otro.Obviously, the device can be composed of any material, be it plastic, wood, metal or any other.
