PLANTILLA DE COLOCACION DE CONECTORES EN FORJADO COLABORANTETEMPLATE OF PLACEMENT OF CONNECTORS IN FORGED COLLABORATING
DE MADERA-HORMIGONOF WOOD-CONCRETE
DESCRIPCIONDESCRIPTION
OBJETO DE LA INVENCIONOBJECT OF THE INVENTION
La presente invention se enmarca en el campo tecnico de la construction. Mas concretamente se propone una plantilla de conectores de forjado colaborante de madera-hormigon que permite la correcta colocation de dichos conectores en las posiciones y con la inclination determinada por los calculos estructurales.The present invention is part of the technical field of construction. More concretely, a template of concrete-wood composite flooring connectors is proposed, which allows the correct colocation of said connectors in the positions and with the inclination determined by the structural calculations.
ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
En edification es frecuente el uso de vigas, viguetas de madera o productos de derivados de la madera para la construccion de forjados. Muchas veces estos forjados se completan con una capa de compresion de hormigon que constituye el suelo de la siguiente planta o la superficie de la cubierta. Estos forjados mixtos a veces se disenan como dos forjados superpuestos que trabajan como estructuras independientes cuya solution es muy poco eficiente.In edification, it is common to use beams, wooden beams or products derived from wood for the construction of slabs. Many times these floors are completed with a layer of concrete compression that forms the floor of the next floor or the surface of the roof. These mixed floors are sometimes designed as two superimposed floors that work as independent structures whose solution is very inefficient.
En otros casos se disenan como un forjado colaborante, es decir, como una unica estructura que trabaja solidariamente distribuyendo las tensiones en la section completa, incluyendo el hormigon junto con la madera o los productos derivados de la madera. Esta solucion obliga a la transmision de esfuerzos entre los dos materiales y a que haya compatibilidad en las deformaciones. Se trata de una solucion es mucho mas eficiente desde un punto de vista estructural.In other cases they are designed as a collaborative slab, that is, as a single structure that works jointly distributing the stresses in the complete section, including the concrete along with the wood or the products derived from the wood. This solution requires the transmission of stress between the two materials and that there is compatibility in the deformations. It is a solution that is much more efficient from a structural point of view.
El forjado colaborante permite reducir el peso y aumentar la rigidez, ademas de reducir o incluso eliminar la armadura resistente en el hormigon. Sin embargo, el forjado colaborante madera-hormigon requiere calculos mas complejos y mayores costes de ejecucion, especialmente si se quiere obtener la maxima eficiencia con los elementos de conexion trabajando principalmente a esfuerzos axiales.The collaborative slab allows to reduce the weight and increase the rigidity, besides reducing or even eliminating the resistant reinforcement in the concrete. However, the wood-concrete composite floor requires more complex calculations and higher costs of execution, especially if maximum efficiency is to be achieved with the connection elements working mainly at axial forces.

Por otra parte, en ocasiones, la fibra neutra de la madera queda incluida en la zona de hormigon, cuando idealmente deberia situarse fuera de ella. Esto provoca que el hormigon trabaje a traction y hace necesaria la colocation de armadura de refuerzo.On the other hand, sometimes, the neutral fiber of the wood is included in the concrete zone, when ideally it should be placed outside it. This causes the concrete to work at traction and makes the placement of reinforcement reinforcement necessary.
DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION
La presente invention presenta una plantilla de colocacion de conectores en forjados de madera-hormigon. El objetivo esencial es proporcionar una plantilla que permite determinar de manera fiable la position en la que hay que colocar los conectores para tener una colaboracion optima entre la madera y el hormigon. Esto permite simplificar las operaciones de colocacion de los conectores y de hormigonado y por tanto se reducen los costes de ejecucion.The present invention presents a template for the placement of connectors in concrete-wood floors. The essential objective is to provide a template that allows to determine in a reliable way the position in which the connectors have to be placed in order to have an optimal collaboration between wood and concrete. This allows to simplify the operations of placement of the connectors and of concreting and therefore the costs of execution are reduced.
En ejemplos de realization de la invencion, la plantilla puede comprender, ademas de orificios para la colocacion de los conectores, indicaciones de la calidad de los materiales del forjado (la madera y el hormigon). La plantilla puede comprender tambien datos de la geometria y la capacidad resistente del forjado.In embodiments of the invention, the template may comprise, in addition to holes for the placement of connectors, indications of the quality of the materials of the floor (wood and concrete). The template can also comprise data of the geometry and the resistant capacity of the floor.
Los orificios de la plantilla estan dispuestos en la posicion exacta en la que se deben colocar los conectores de clavija. Asimismo dichos orificios tienen una determinada inclination respecto a la viga. Esta inclination determina el angulo de inclination con el que hay que colocar los conectores.The holes of the template are arranged in the exact position in which the plug connectors must be placed. Also said holes have a certain inclination with respect to the beam. This inclination determines the angle of inclination with which the connectors must be placed.
La distancia a la que se introducen los conectores tambien puede estar determinada por los orificios. En algunos ejemplos de realizacion la plantilla comprende adicionalmente unos tetones que se alojan en los orificios. Los tetones tienen la misma inclinacion que los orificios en los que se introducen y colaboran por tanto en el guiado de los conectores. En algunos casos estos tetones permiten determinar la posicion exacta de la cabeza de los conectores. En otros casos la plantilla puede comprender unas piezas adicionales que se unen a los tetones y que tienen estas funciones.The distance to which the connectors are inserted can also be determined by the holes. In some embodiments, the template additionally comprises lugs which are housed in the holes. The lugs have the same inclination as the holes in which they are introduced and thus collaborate in guiding the connectors. In some cases these lugs allow to determine the exact position of the head of the connectors. In other cases, the template may comprise additional pieces that are joined to the lugs and that have these functions.
Los orificios estan dispuestos en las posiciones determinadas por los calculos estructurales que se determinan en funcion de las cargas a las que se vaya a someter el forjado.The holes are arranged in the positions determined by the structural calculations that are determined as a function of the loads to which the slab will be subjected.

Se propone una plantilla de conectores de forjado colaborante de madera-hormigon como la que se muestra por ejemplo en las figuras 1-4.A template of concrete-wood composite flooring connectors is proposed, as shown for example in figures 1-4.
Esta plantilla esta configurada para unirse a una viga (2) o vigueta de madera y asegurar el correcto posicionamiento de los conectores. Comprende al menos un cuerpo principal (1) configurado para unirse a la viga (2). Dicho cuerpo principal (1) comprende al menos una cara inferior, destinada a quedar en contacto con dicha viga (2); una cara superior, opuesta a la cara inferior; unos extremos laterales que unen la cara inferior y la cara superior en direccion longitudinal del cuerpo principal (1); y un extremo frontal y un extremo posterior, opuestos entre si, que unen la cara inferior y la cara superior en direccion transversal del cuerpo principal (1).This template is configured to join a beam (2) or wooden beam and ensure the correct positioning of the connectors. It comprises at least one main body (1) configured to join the beam (2). Said main body (1) comprises at least one lower face, intended to be in contact with said beam (2); an upper face, opposite the lower face; lateral ends joining the lower face and the upper face in the longitudinal direction of the main body (1); and a front end and a rear end, opposite each other, joining the lower face and the upper face in the transverse direction of the main body (1).
La clave de la plantilla de la presente invention es que el cuerpo principal (1) comprende adicionalmente una pluralidad de orificios (3) pasantes que se extienden entre la cara superior y la cara inferior. Dichos orificios (3) estan distribuidos alineados entre si en al menos una llnea recta y estan inclinados, cada uno de ellos a 45° o -45° respecto a la superficie de la viga (2).The key of the template of the present invention is that the main body (1) additionally comprises a plurality of through holes (3) extending between the upper face and the lower face. Said holes (3) are distributed aligned with each other in at least one straight line and are inclined, each one at 45 ° or -45 ° with respect to the surface of the beam (2).
Estos orificios (3) estan destinados a recibir a los conectores de tal manera que los conectores quedan parcialmente alojados en la viga (2) y parcialmente dispuestos a traves de los orificios (3). Los orificios (3) estan dispuestos en posiciones concretas previamente determinadas mediante calculos estructurales. Dichos calculos tienen en cuanta la geometrla del forjado, las cargas previstas durante la vida util de este, etc.These holes (3) are intended to receive the connectors in such a way that the connectors are partially housed in the beam (2) and partially arranged through the holes (3). The holes (3) are arranged in specific positions previously determined by structural calculations. These calculations take into account the geometry of the floor, the loads planned during the useful life of this, etc.
Asl pues, la plantilla permite el correcto posicionamiento de los conectores, preferentemente de tipo clavija, en la viga (2) o vigueta antes del vertido del hormigon. En un ejemplo de realization preferente los orificios (3) estan distribuidos alineados entre si en varias llneas rectas, paralelas entre si.Thus, the template allows the correct positioning of the connectors, preferably of the pin type, on the beam (2) or joist before the pouring of the concrete. In an example of preferred embodiment the holes (3) are distributed aligned with each other in several straight lines, parallel to each other.
La plantilla puede comprende tambien unos medios de fijacion mecanicos para su union a la viga (2). Esto permite asegurar que no haya desplazamiento de la plantilla durante la operation de colocation de los conectores. En un ejemplo de realizacion los medios de fijacion mecanicos pueden ser tornillerla que atraviesa unos agujeros pasantes (4) en al menos dos extremos opuestos del cuerpo principal (1).The jig may also comprise mechanical fastening means for joining it to the beam (2). This ensures that there is no displacement of the template during the colocation operation of the connectors. In an exemplary embodiment, the mechanical fastening means can be a bolt through a through hole (4) in at least two opposite ends of the main body (1).

En funcion de las caracterlsticas de la obra y de los materiales empleados, la plantilla puede ser fija de un solo uso o bien puede ser reutilizable. Preferentemente el cuerpo principal (1) esta fabricado en plastico, acero, fibra de carbono, madera o productos derivados de la madera. En el caso de las plantillas de madera se usara madera con el tratamiento necesario para garantizar su durabilidad.Depending on the characteristics of the work and the materials used, the template can be fixed for a single use or it can be reusable. Preferably the main body (1) is made of plastic, steel, carbon fiber, wood or wood products. In the case of wooden templates, wood with the necessary treatment will be used to guarantee its durability.
En las figuras 1 y 2 se muestra una plantilla que se queda fija en la viga (2) o vigueta. Como se puede observar, en la figura 1 se ha representado la plantilla (1) ya unida a dicha viga (2) tal y como queda en la posicion final de trabajo. En la figura se aprecia la cara superior del cuerpo principal (1) de la plantilla con los orificios (3) para los conectores. Para que se pueda observar mejor la inclinacion de los orificios (3), en la figura 2 se ha representado una vista de una plantilla como la de la figura 1 pero translucida. De esta forma se puede apreciar la inclinacion de dichos orificios (3). Se han senalado tambien los agujeros pasantes (4) para los medios de fijacion mecanica del cuerpo principal (1) a la viga (2).Figures 1 and 2 show a template that remains fixed on the beam (2) or joist. As can be seen, in figure 1 the template (1) already attached to said beam (2) has been represented as it is in the final work position. The figure shows the upper face of the main body (1) of the template with the holes (3) for the connectors. So that the inclination of the holes (3) can be better observed, in figure 2 a view of a template like that of figure 1 but translucent has been represented. In this way, the inclination of said holes (3) can be appreciated. The through holes (4) for the mechanical fastening means of the main body (1) to the beam (2) have also been pointed out.
En las figuras 3 y 4 se ha representado un ejemplo de realizacion en el que la plantilla es reutilizable. En este caso, como se observa en dichas figuras, el cuerpo principal (1) comprende adicionalmente unas ranuras (5). Estas se extienden entre la cara superior y la cara inferior, partiendo desde cada orificio (3), con la misma inclinacion que cada uno de ellos, hasta un extremo lateral del cuerpo principal (1).An exemplary embodiment in which the template is reusable is shown in FIGS. 3 and 4. In this case, as seen in said figures, the main body (1) additionally comprises grooves (5). These extend between the upper face and the lower face, starting from each hole (3), with the same inclination as each of them, until a lateral end of the main body (1).
Asl pues, las ranuras (5) conectan cada orificio (3) con el exterior del cuerpo principal (1). Esto permite que, despues de haber instalado los conectores en sus posiciones, se pueda desplazar la plantilla en direccion opuesta a la de las ranuras (5) manteniendo los conectores fijos hasta que se retira totalmente la plantilla. El hormigonado se hace despues de haber retirado la plantilla. En la figura 3 se muestra una plantilla reutilizable en la que se pueden observar las ranuras (5) descritas.Thus, the grooves (5) connect each hole (3) with the outside of the main body (1). This allows, after having installed the connectors in their positions, it is possible to move the template in opposite direction to that of the slots (5) keeping the connectors fixed until the template is completely removed. Concreting is done after having removed the template. Figure 3 shows a reusable template in which the slots (5) described can be observed.
Asimismo, la figura 4 muestra otro ejemplo de realizacion en el que, ademas de ser reutilizable, la plantilla comprende unos tetones (6) configurados para quedar alojados en los orificios (3) y que comprenden al menos un canal interior pasante (7) configurado para recibir los conectores. La plantilla tambien puede comprender tetones (6) en las realizaciones en las que no es reutilizable.Likewise, Figure 4 shows another example of embodiment in which, in addition to being reusable, the template comprises lugs (6) configured to be housed in the holes (3) and comprising at least one internal passageway (7) configured to receive the connectors. The template may also comprise lugs (6) in embodiments where it is not reusable.

En los casos en los que la plantilla no es reutilizable y comprende tetones (6), estos son cuerpos cilmdricos y el canal interior pasante (7) tiene seccion circular. En los casos en los que la plantilla si que es reutilizable y comprende tetones (6) (como en la figura 4), estos son cuerpos semicilmdricos y el canal interior pasante (7) es una acanaladura orientada hacia la correspondiente ranura (5) tal que el canal interior pasante (7) queda conectado con el exterior del cuerpo principal (1) a traves de dicha ranura (5).In the cases in which the template is not reusable and comprises lugs (6), these are cylindrical bodies and the inner passageway (7) has a circular section. In the cases in which the insole is reusable and comprises lugs (6) (as in Figure 4), these are semicylindric bodies and the inner passageway (7) is a groove oriented towards the corresponding slot (5) such that the inner passageway (7) is connected to the outside of the main body (1) through said slot (5).
En las realizaciones en las que la plantilla comprende tetones (6), el cuerpo principal (1) puede ser de menor espesor ya que los tetones (6) actuan como una prolongation de los orificios (3) y permiten mantener una longitud suficiente de guiado de los conetores.In the embodiments in which the insole comprises lugs (6), the main body (1) can be of smaller thickness since the lugs (6) act as an extension of the holes (3) and allow to maintain a sufficient length of guidance of the connectors.
Los tetones (6) pueden ser cortos, simplemente para colaborar en el posicionamiento del conector, o bien pueden tener una longitud concreta para, ademas, determinar la altura a la que debe quedar dispuesta la cabeza del conector. En este caso, segundo los tetones (6) tienen una longitud tal que sumada a la longitud del orificio (3) coincide con la longitud del conector que debe quedar fuera de la viga (2). En la figura 5 se muestran unos ejemplos de tetones (6), de un solo uso y reutilizables, con diferentes longitudes.The lugs (6) can be short, simply to assist in the positioning of the connector, or they can have a specific length to, in addition, determine the height at which the head of the connector should be arranged. In this case, second the lugs (6) have a length such that added to the length of the hole (3) coincides with the length of the connector that must be outside the beam (2). Figure 5 shows some examples of lugs (6), single-use and reusable, with different lengths.
Los tetones (6) estan preferentemente fabricados en plastico, acero, fibra de carbono, madera o productos derivados de la madera.The lugs (6) are preferably made of plastic, steel, carbon fiber, wood or wood products.
En otro ejemplo de realization, la plantilla puede comprender adicionalmente unas piezas auxiliares (8) con taladro pasante (9). Estas piezas auxiliares (8) se aprecian en la figura 6, donde se han representado en relation a unos tetones (6) ya que estan configuradas para unirse a ellos. Las piezas auxiliares (8) estan configuradas para limitar la introduction del conector en la viga (2). Es decir, permiten determinar la colocation optima de la cabeza de los conectores.In another embodiment example, the jig can additionally comprise auxiliary parts (8) with through bore (9). These auxiliary parts (8) are shown in Figure 6, where they have been represented in relation to lugs (6) since they are configured to join them. The auxiliary parts (8) are configured to limit the introduction of the connector in the beam (2). That is, they allow to determine the optimal colocation of the head of the connectors.
Las piezas auxiliares (8) se pueden unir a los tetones (6) acoplandose exteriormente a ellos o alojandose al menos parcialmente en el canal interior pasante (7) de los tetones (6) tal que el taladro pasante (9) queda alineado con el canal interior pasante (7). Como se puede ver en dicha figura 6, las piezas auxiliares (8) tambien puede ser, igual que los tetones (6), de un solo uso o reutilizables. Asimismo, igual que losThe auxiliary parts (8) can be attached to the lugs (6) by engaging them externally or at least partially housed in the inner passageway (7) of the lugs (6) such that the through bore (9) is aligned with the inner passage channel (7). As can be seen in said figure 6, the auxiliary pieces (8) can also be, like the lugs (6), single-use or reusable. Likewise, like

tetones (6), pueden ser plastico, acero, fibra de carbono, madera o productos derivados de la madera.lugs (6), can be plastic, steel, carbon fiber, wood or wood products.
En un ejemplo de realization los orificios (3) pueden ser orificios roscados. En otro ejemplo de realizacion, los tetones (6) y/o las piezas auxiliares (8) pueden ser parte de una pieza unica junto con el cuerpo principal (1).In a realization example the holes (3) can be threaded holes. In another embodiment, the lugs (6) and / or the auxiliary parts (8) can be part of a single piece together with the main body (1).
En la figura 7 se muestra un ejemplo de realizacion en el que la plantilla comprende adicionalmente unos elementos de anclaje (10) conformados por unas prolongaciones que se extienden desde un extremo lateral del cuerpo principal (1). Las prolongaciones comprenden en su extremo un tope configurado para quedar enrasado con un extremo lateral de la viga (2). Esta realizacion permite facilitar las labores de posicionamiento de la plantilla en la viga (2).Figure 7 shows an example embodiment in which the template additionally comprises anchoring elements (10) formed by extensions extending from a side end of the main body (1). The extensions comprise at their end a stop configured to be flush with a lateral end of the beam (2). This embodiment makes it possible to facilitate the tasks of positioning the template on the beam (2).
En otro ejemplo de realizacion, el cuerpo principal (1) es telescopico y se pliega en direction longitudinal. Preferentemente el cuerpo principal (1) comprende al menos una marca que indica el centro del cuerpo principal (1) y marcas en los extremos laterales con diferentes metricas que permiten emplear la plantilla como regla. En un ejemplo, el cuerpo principal (1) se pliega telescopicamente desde el centro.In another embodiment, the main body (1) is telescopic and folded in the longitudinal direction. Preferably the main body (1) comprises at least one marking indicating the center of the main body (1) and markings on the lateral ends with different metrics that allow the template to be used as a rule. In one example, the main body (1) telescopically folds from the center.
Como se ha descrito previamente, los conectores se emplean en los forjados de madera-hormigon para aseguar que ambos materiales se comporten de la misma manera, para mejorar asl la resistencia del forjado. En los casos en los que la plantilla no es reutilizable y se queda en el interior del forjado tras el hormigonado, unida a la madera, el cuerpo principal (1) puede comprender una pluralidad de muescas configuradas para aumentar la transferencia de esfuerzos entre dicho cuerpo principal (1) y la viga (2). Estas muescas pueden ser por ejemplo ranurados, laminados, elementos puntiagudos o una combination de estos. Asimismo, el cuerpo principal (1) puede comprender en su cara superior otras muescas, como por ejemplo corrugados o resaltos, para mejorar la transferencia de esfuerzos con el hormigon.As previously described, the connectors are used in the concrete-wood slabs to ensure that both materials behave in the same way, to improve the strength of the slab. In cases where the template is not reusable and remains inside the floor after concreting, joined to the wood, the main body (1) can comprise a plurality of notches configured to increase the transfer of stress between said body main (1) and the beam (2). These notches may be for example grooved, laminated, pointed elements or a combination of these. Likewise, the main body (1) can comprise on its upper face other notches, such as for example corrugated or protrusions, to improve the stress transfer with the concrete.
En otra realizacion de la invention la plantilla puede comprender adicionalmente unas bandas de material elastomerico (11). Esta realizacion esta disenada para los casos en los que la plantilla no es reutilizable. Las bandas de material elastomerico (11) estan dispuestas al menos a lo largo de los extremos laterales del cuerpo principal (1) para queIn another embodiment of the invention, the template may additionally comprise bands of elastomeric material (11). This embodiment is designed for cases in which the template is not reusable. The bands of elastomeric material (11) are arranged at least along the lateral ends of the main body (1) so that
esta encaje perfectamente en el encofrado perdido durante la operation de hormigonado. De esta forma se evitan fugas de hormigon o lechadas de cemento.This fits perfectly into the formwork lost during the concreting operation. In this way, concrete leaks or cement slurries are avoided.
