Sistema de conexion oculto con chapa de acero encolada en estructuras de madera.Hidden connection system with steel sheet glued on wooden structures.
Sector de la tecnicaSector of the technique
La presente invention pertenece al sector de las estructuras de madera y mas concretamente al campo de las uniones entre elementos estructurales de madera.The present invention belongs to the sector of wood structures and more specifically to the field of joints between wooden structural elements.
El objeto principal de la presente invencion es la resolution de uniones entre elementos estructurales de madera tales como vigas, pilares o porticos, de manera eficaz, dotando a la union entre los distintos elementos de la continuidad y rigidez necesarias.The main object of the present invention is the resolution of joints between wooden structural elements such as beams, pillars or porticos, effectively, providing the union between the various elements of the necessary continuity and rigidity.
Antecedentes de la invencionBackground of the invention
La ejecucion de estructuras de madera conlleva la union de piezas de diferentes secciones y tipologlas entre si. Las uniones entre los distintos elementos estructurales suponen puntos singulares en los que es necesario realizar un estudio pormenorizado de los mismos puesto que el fallo de una de las uniones puede suponer el colapso de la estructura.The execution of wooden structures involves the union of pieces of different sections and typologies among themselves. The unions between the different structural elements suppose singular points in which it is necessary to carry out a detailed study of the same since the failure of one of the unions can suppose the collapse of the structure.
Tradicionalmente las estructuras se han resuelto mediante las denominadas uniones carpinteras o uniones tradicionales que basan su metodo de union en el mecanizado y ensamblado de la madera reduciendo al mlnimo el empleo de otros materiales.Traditionally the structures have been solved by means of the denominated carpenter unions or traditional unions that base their method of union in the mechanized and assembled of the wood reducing to the minimum the use of other materials.
En las uniones tradicionales, los esfuerzos se transmiten de un elemento a otro a traves de cajas o rebajes y espigas o llaves, transmitiendo los esfuerzos axiles de la estructura en base a compresion y esfuerzo tangencial.In traditional joints, the stresses are transmitted from one element to another through boxes or recesses and spikes or keys, transmitting the axial forces of the structure based on compression and tangential effort.
El empleo de elementos metalicos tales como tornillos o puntas, en las uniones tradicionales solo cumple la funcion de impedir el desplazamiento relativo entre piezas y el consecuente desarmado de la union.The use of metallic elements such as screws or points, in the traditional joints only fulfills the function of preventing the relative displacement between pieces and the consequent disassembly of the joint.
Si bien en la actualidad la existencia de maquinaria de control numerico reduce la dificultad de la ejecucion de los mecanizados, en las decadas anteriores la necesidad de mano de obra especializada para su ejecucion doto de preferencia al empleo de las denominadas uniones mecanicas, siendo las uniones mas empleadas en la actualidad.While currently the existence of numerical control machinery reduces the difficulty of the execution of machining, in the previous decades the need for skilled labor for its execution preferably given to the use of so-called mechanical unions, being the unions most used today.
Las uniones mecanicas son aquellas que se sirven de herrajes metalicos para la transmision de esfuerzos. A su vez, dentro de las uniones mecanicas podemos distinguir las uniones tipo clavija, entendiendo por clavija los clavos, grapas, tirafondos, pernos y pasadores. El metodo de fijacion se basa en transmitir los esfuerzos mediante herrajes metalicos a traves de tensiones de aplastamiento sobre las piezas de madera.Mechanical joints are those that use metal fittings for the transmission of stresses. At the same time, inside the mechanical joints we can distinguish the peg-type connections, meaning nails, staples, screws, bolts and pins. The method of fixation is based on transmitting the efforts through metal fittings through stresses of crushing on the pieces of wood.
Otro tipo de union mecanica lo constituyen las uniones con conectores donde el esfuerzo se transmite a traves del aumento de la superficie de contacto. Reciben el nombre de conectores los elementos de fijacion con forma de placa con resaltos, placa dentado o anillo, que se introducen ajustados entre dos piezas de madera y se fijan mediante un perno que atraviesa las piezas.Connections with connectors where the effort is transmitted through the increase of the contact surface. They receive the name of connectors the fixation elements in the form of plate with projections, toothed plate or ring, which are inserted tight between two pieces of wood and fixed by a bolt that crosses the pieces.
Explication de la invencionExplanation of the invention
El metodo de resolucion de union entre elementos estructurales de madera objeto de la invencion comprende tres elementos principales (estructura de madera, resina epoxi y herraje metalico) que permiten resolver los nudos de la estructura de manera rlgida y segura. The method of bonding between wooden structural elements object of the invention comprises three main elements (wood structure, epoxy resin and metal hardware) that allow to solve the knots of the structure in a rigid and safe manner.
Las ventajas principales de esta invention se resumen a continuation:The main advantages of this invention are summarized below:
• El herraje metalico se introduce en la union y los esfuerzos se transmiten entre los elementos de madera del nudo mediante las tensiones en el contacto de la madera con la resina y de esta con el herraje, siendo innecesario aprietes de tornillos que con el tiempo pudieran necesitar ser reajustados.• The metal fitting is introduced into the joint and the stresses are transmitted between the wooden elements of the knot by the tensions in the contact of the wood with the resin and of this with the fitting, being unnecessary tightening of screws that with time could need to be readjusted.
• En zonas de especial humedad, el herraje queda totalmente embebido en la union y por tanto no expuesto a la humedad del ambiente ni a los problemas de corrosion asociados a la misma.• In areas of special humidity, the fitting is fully embedded in the joint and therefore not exposed to the humidity of the environment or the corrosion problems associated with it.
• En caso de incendio, el herraje metalico queda protegido por la madera, que carbonizara en su superficie exterior en contacto con las llamas y mantendra la section suficiente para garantizar la union durante el tiempo requerido.• In the event of fire, the metal fitting is protected by the wood, which will carbonize on its outer surface in contact with the flames and keep the section sufficient to guarantee the union during the required time.
Para la ejecucion de la union, son necesarios dos o mas elementos de madera que confluyen en un mismo nudo, un herraje metalico que queda totalmente embebido en los elementos de madera y la resina epoxi que rellena los huecos existentes entre el herraje metalico y la madera.For the execution of the union, two or more wooden elements are required that come together in the same knot, a metal fitting that is completely embedded in the wooden elements and the epoxy resin that fills the gaps between the metal fitting and the wood. .
Los elementos de madera que confluyen en un nudo presentan en sus extremos unos ranurados o cajeados realizados mediante control numerico en los que se insertara el herraje metalico. Dichos ranurados o cajeados, seran de tamano suficiente para albergar el herraje y tendran unos millmetros de holgura para conseguir que la resina epoxi penetre y rellene los huecos existentes entre el herraje metalico y la madera.The wooden elements that come together in a knot have slotted or recessed ends made by numerical control in which the metal fitting is inserted. These slotted or recessed, will be of sufficient size to house the hardware and will have a few millimeters of slack to get the epoxy resin penetrate and fill the gaps between the metal hardware and wood.
Se tendra en cuenta el ancho de los elementos de madera a unir para determinar si es necesario un cajeado o dos en el extremo del mismo con el fin de transmitir los esfuerzos de manera eficaz. Los ranurados o cajeados realizados no seran pasantes, pudiendo sostenerse el herraje metalico en la union durante el vertido sin necesidad de ningun elemento de fijacion. The width of the wooden elements to be joined will be taken into account to determine if a recess or two at the end thereof is necessary in order to transmit the efforts effectively. The grooves or grooves made will not be through, being able to hold the metal fitting in the joint during the pouring without the need of any fixing element.
Los herrajes metalicos empleados seran chapas de acero con tantas "alas” como elementos a unir. El espesor y dimensiones de las chapas de acero se determinaran en funcion de los esfuerzos de la union y del tamano de los elementos a unir.The metal fittings used will be steel sheets with as many "wings" as elements to be joined The thickness and dimensions of the steel sheets will be determined depending on the efforts of the union and the size of the elements to be joined.
Ha de prevenirse la corrosion del acero previo a su introduction en la union, por ello se aplicara una resina epoxi de imprimacion a los herrajes protegiendolos de la corrosion. Una vez realizada la union del herraje de acero con la madera mediante la resina epoxi adhesiva, el herraje queda totalmente oculto evitando asl su exposition al ambiente.Prevent corrosion of the steel prior to its introduction into the union, for this reason a priming epoxy resin will be applied to the fittings protecting them from corrosion. Once the union of the steel hardware with the wood by means of the adhesive epoxy resin, the hardware is totally hidden avoiding its exposure to the environment.
Con el fin de mejorar la superficie de contacto entre el herraje de acero y la madera materializada con la resina epoxi, la superficie del herraje sera rugosa y con estrlas, aumentado asl la superficie de union.In order to improve the contact surface between the steel fitting and the wood materialized with the epoxy resin, the surface of the fitting will be rough and stiff, thus increasing the joint surface.
Previo al vertido de la resina epoxi, se disponen los elementos de madera segun la disposition definitiva del nudo a resolver. Se sellaran las testas de los elementos a unir con el fin de evitar que la resina escurra por las holguras existentes en la union.Prior to the pouring of the epoxy resin, the wooden elements are arranged according to the final disposition of the knot to be solved. The heads of the elements to be joined will be sealed in order to prevent the resin from running through the gaps existing in the joint.
Se dispone el herraje en su position definitiva dentro del ranurado o cajeado garantizando que haya espacio suficiente en todas las superficies de contacto del herraje por las que penetre la resina epoxi. The fitting is arranged in its final position in the slotted or slotted area, ensuring that there is sufficient space in all the contact surfaces of the fitting through which the epoxy resin penetrates.
La resina epoxi se presenta mediante dos componentes separados en distintos recipientes. Uno de ellos contiene la resina epoxi mientras que el otro es un endurecedor. Ambos llquidos se mezclan mediante agitador mecanico en un solo recipiente que posteriormente se empleara para el vertido de la resina en la union. El soporte de la mezcla debera estar limpio, exento de polvo, aceites o grasas.The epoxy resin is presented by two separate components in different containers. One of them contains the epoxy resin while the other one is a hardener. Both liquids are mixed by mechanical agitator in a single container that will later be used for pouring the resin into the joint. The support of the mixture should be clean, free of dust, oils or grease.
La reaccion entre ambos componentes es una reaccion exotermica, por lo que se tomaran las medidas de seguridad asociadas a la misma como el empleo de guantes.The reaction between both components is an exothermic reaction, so that the safety measures associated with it will be taken, such as the use of gloves.
El fluido resultante es de consistencia viscosa y permite penetrar en holguras de entre 2 y 4 mm de anchura minima. La temperatura de aplicacion oscilara entre los 10°C y los 35 °C.The resulting fluid is of viscous consistency and allows to penetrate into clearances of between 2 and 4 mm minimum width. The application temperature will oscillate between 10 ° C and 35 ° C.
Una vez conseguida la mezcla eficaz de ambos componentes apreciandose la homogeneidad del llquido resultante y la inexistencia de grumos de alguno de los componentes, se puede proceder al vertido de la resina epoxi en la union.Once the effective mixing of both components has been achieved, recognizing the homogeneity of the resulting liquid and the absence of lumps of any of the components, the epoxy resin can be poured into the joint.
El vertido de la resina se realiza de manera manual, vertiendo la misma por gravedad en la union y garantizando que la resina epoxi penetra y rellena todos los huecos existentes entre el herraje metalico y la madera.The pouring of the resin is done manually, pouring it by gravity in the union and ensuring that the epoxy resin penetrates and fills all the existing gaps between the metal hardware and wood.
El endurecido de la union a temperatura ambiente se produce en las 24 horas posteriores al vertido. Una vez endurecida la resina, la union queda garantizada y no es necesario ningun tratamiento posterior.Hardening of the union at room temperature occurs within 24 hours after pouring. Once the resin has hardened, the union is guaranteed and no further treatment is necessary.
