Description

DESCRIPCIÓN DESCRIPTION
JUNTA PARA MADERA JOINT FOR WOOD
CAMPO DE LA INVENCIÓN FIELD OF THE INVENTION
La presente invención corresponde a una junta para madera que permite unir dos piezas de forma sencilla, resistente y sin requerir elementos metálicos como clavos o tornillos que afectan a la vida de la junta. The present invention corresponds to a joint for wood that allows two pieces to be joined in a simple, resistant way and without requiring metallic elements such as nails or screws that affect the life of the joint.
ESTADO DE LA TÉCNICA ANTERIOR PRIOR STATE OF THE ART
Es necesario abandonar el hormigón y el acero para sustituirlo por materiales constructivos ecológicos, destacando la madera por encima del resto. Para ello, se ha de lograr un sistema estructural que potencie el uso de la madera como elemento estructural, ya que se trata un agente reductor del impacto medioambiental siendo capaz de almacenar en su interior una tonelada de CO2 por cada metro cúbico de madera. It is necessary to abandon concrete and steel to replace it with ecological construction materials, emphasizing wood above the rest. To do this, a structural system must be achieved that promotes the use of wood as a structural element, since it is an agent that reduces environmental impact, being capable of storing one ton of CO2 inside for each cubic meter of wood.
En el estado de la técnica se conocen diversas formas de realizar juntas entre piezas de madera. En primer lugar, se puede insertar una parte de metal, clavo o tornillo, que fija ambas piezas. Sin embargo, este tipo de partes genera estrés en la madera y puede acabar rompiéndola. Por eso la siguiente forma implica usar dos elementos metálicos, que se acoplan entre sí para no afectar a las piezas de madera. Una tercer opción es la utilización de espárragos de madera que se insertan en orificios en ambas piezas. Various ways of making joints between pieces of wood are known in the state of the art. First of all, a metal part, nail or screw, can be inserted, which fixes both pieces. However, this type of part generates stress in the wood and can end up breaking it. That's why the following way involves using two metal elements, which are attached to each other so as not to affect the wooden pieces. A third option is the use of wooden studs that are inserted into holes in both pieces.
También se conoce la fijación mediante adhesivos, como en W02016024039 o por la generación de dientes en ambas piezas que se engranan, como en EP2894271 o GB1478295. Estas soluciones se consideran el estado de la técnica más cercano. Fixing by means of adhesives is also known, as in W02016024039 or by the generation of teeth in both pieces that mesh, as in EP2894271 or GB1478295. These solutions are considered the closest state of the art.
Cada una de estas fijaciones ofrece sus propias ventajas, pero no alcanza la resistencia de la invención. Each of these fixings offers its own advantages, but falls short of the strength of the invention.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
La invención es una unión para madera según la reivindicación independiente. Sus vahantes se definen en las demás reivindicaciones y se describen en el resto de la memoria. Permite la unión de piezas de madera, preferiblemente vigas y pilares de madera y cruceros o viguetas de madera entre las vigas, de forma que la unión se produce sin utilizar elementos metálicos de refuerzo. Así, logra una resistencia elevada sin afectar a la vida útil de la madera. The invention is a joint for wood according to the independent claim. Its variants are defined in the other claims and described in the remainder of the specification. It allows the joining of wooden pieces, preferably wooden beams and pillars and crosses or wooden joists between the beams, so that the union occurs without using metallic reinforcing elements. Thus, it achieves high resistance without affecting the useful life of the wood.
La unión permite realizar una unión rápida, resistente y que reduce el tiempo de fabricación y elimina el uso del acero en las construcciones de madera consiguiendo un ensamble de piezas en seco. Se han realizado ensayos de este tipo de uniones, utilizando piezas en “H” con una unión en cada extremo de la barra horizontal. Este sistema puede reemplazar a los sistemas actuales estructurales de madera y acero por un sistema estructural de ensamble de madera en seco. The union allows a fast, resistant union that reduces manufacturing time and eliminates the use of steel in wooden constructions, achieving a dry assembly of parts. Tests of this type of joints have been carried out, using “H” pieces with a joint at each end of the horizontal bar. This system can replace existing wood and steel structural systems with a dry-assembled wood structural system.
Para ello, la unión de madera realiza la unión de dos piezas: una primera pieza con una caja y una segunda pieza con un entrante. La caja o vaciado posee una primera parte de mayor anchura y una segunda parte de anchura decreciente. El entrante tiene forma conjugada a la segunda parte de la caja. De esta forma el entrante puede situarse dentro de la caja al entrar, al menos parcialmente, por la primera parte. Además, las paredes de la segunda parte y del entrante tienen dientes complementarios. Estos dientes estarán en las paredes que contactan en el uso para poder engranar. To do this, the wooden joint joins two pieces: a first piece with a box and a second piece with a recess. The box or emptying has a first part of greater width and a second part of decreasing width. The incoming has a conjugate shape to the second part of the box. In this way the entrant can be located inside the box when entering, at least partially, through the first part. In addition, the walls of the second part and the recess have complementary teeth. These teeth will be on the walls that they contact in use in order to engage.
Preferiblemente los dientes son sinusoidales para disminuir el riesgo de roturas o desgaste. También pueden ser trapezoidales. Preferably the teeth are sinusoidal to reduce the risk of breakage or wear. They can also be trapezoidal.
El propio peso de las piezas puede mantener la unión en la posición correcta, pero es preferible disponer un taco o tope en la primera parte de la caja para impedir el movimiento de retorno del entrante. El taco se puede disponer de varias formas. Por ejemplo, por un orificio ad hoc, disponiendo el entrante en un borde de la segunda pieza, de forma que la primera parte queda accesible... Este tope puede quedar a ras en la primera pieza o no. Por ejemplo, puede tener un asa para hacer que la junta sea fácilmente desmontable. The weight of the pieces itself can keep the joint in the correct position, but it is preferable to have a block or stop in the first part of the box to prevent the return movement of the recess. The plug can be arranged in various ways. For example, through an ad hoc hole, arranging the recess on one edge of the second piece, so that the first part is accessible... This stop can be flush with the first piece or not. For example, it may have a handle to make the gasket easily removable.
Si la superficie de contacto es suficientemente grande, se puede aumentar la resistencia haciendo que cada pieza posea una caja y un entrante en orientación opuesta. Así es posible introducir ambos entrantes en las cajas respectivas en un único movimiento. La caja y el entrante de cada pieza pueden estar alineados o no (eje de simetría coincidente). Cuando no están alineados aumenta la resistencia a la torsión. Igualmente, es conveniente que la segunda parte de la caja tenga un eje de simetría para equilibrar fuerzas. Cuando están alineados, es preferible que el entrante esté adyacente a la primera parte de la caja. Así se simplifica el bloqueo de las piezas al colocar el tope, pues sólo es necesario uno. Este tope requiere un orificio de entrada. If the contact area is large enough, resistance can be increased by having each part have a pocket and a recess in opposite orientation. Thus it is possible to introduce both starters in the respective boxes in a single movement. The box and the recess of each piece can be aligned or not (coinciding axis of symmetry). When they are not aligned, the resistance to torsion increases. Likewise, it is convenient that the second part of the box has an axis of symmetry to balance forces. When aligned, it is preferable for the recess to be adjacent to the first part of the box. This simplifies the blocking of the pieces when placing the stop, since only one is necessary. This stop requires an entry hole.

EXPOSICIÓN DETALLADA DE MODOS DE REALIZACIÓN DETAILED EXPOSURE OF PERFORMANCE WAYS
Se describe a continuación una serie de formas de realizar la invención, como ejemplos descriptivos pero que no buscan limitar la invención. A series of ways of carrying out the invention are described below, as descriptive examples but not intended to limit the invention.
En las figuras se muestran vahas formas de unir dos piezas (1 ,2) de madera. Como se puede apreciar, la unión puede ser en ángulo o coaxial. The figures show various ways of joining two pieces (1,2) of wood. As can be seen, the joint can be angled or coaxial.
En las figuras se aprecia una primera pieza (1) con una caja (3) o parte hembra y una segunda pieza (2) con un entrante (4) o parte macho, configurada para introducirse y fijarse en la caja (3). La caja (3) tiene dos partes principales, una primera parte (5) de mayor anchura, y una segunda parte (6) de anchura decreciente según se aleja de la primera parte (5). En las figuras, la primera parte (5) es aproximadamente rectangular y la segunda parte (6) es trapezoidal, simétrica. The figures show a first piece (1) with a box (3) or female part and a second piece (2) with a recess (4) or male part, configured to be inserted and fixed in the box (3). The box (3) has two main parts, a first part (5) of greater width, and a second part (6) of decreasing width as it moves away from the first part (5). In the figures, the first part (5) is approximately rectangular and the second part (6) is trapezoidal, symmetrical.
Por su parte, el entrante (4) posee forma conjugada a la segunda parte (6), de forma que puede apoyarse en ella por toda la pared de la segunda parte (6). Por ello, es preferiblemente trapezoidal. Esa pared de la segunda parte (6) posee una serie de primeros dientes (7) que pueden ser triangulares, cuadrados, trapezoidales... pero que preferiblemente son sinusoidales, es decir, curvos. Los primeros dientes (7) se corresponden con segundos dientes (8) en la pared correspondiente del entrante (4). Así, cuando el entrante (4) se apoya en la segunda parte (6), los dientes (7,8) se engranan unos en otros para aumentar la resistencia de esa unión. For its part, the recess (4) has a conjugated shape to the second part (6), so that it can be supported by the entire wall of the second part (6). Therefore, it is preferably trapezoidal. That wall of the second part (6) has a series of first teeth (7) that can be triangular, square, trapezoidal... but that are preferably sinusoidal, that is, curved. The first teeth (7) correspond to second teeth (8) on the corresponding wall of the recess (4). Thus, when the recess (4) rests on the second part (6), the teeth (7,8) mesh with each other to increase the resistance of that union.
Los primeros dientes (7) se pueden realizar con una fresa como la mostrada en la figura 3. Comprende un vástago central y una serie de salientes radiales que realizan los valles entre primeros dientes (7). The first teeth (7) can be made with a cutter like the one shown in figure 3. It comprises a central stem and a series of radial projections that make the valleys between the first teeth (7).
Como se aprecia en las figuras, la unión de las piezas (1 ,2) se realiza colocando el entrante (4) enfrentado a la primera parte (5) de la caja (3) y el movimiento del entrante hacia abajo, hacia la segunda parte (6). Así los dientes (7,8) se engranan y no es posible extraer el entrante (4) de la caja (3) salvo hacia arriba. Una vez colocado el entrante (4) en la segunda parte (6) se puede colocar un tope (9) o taco en la primera parte (5) de forma que impide el movimiento de retorno. Preferiblemente la situación del entrante (4) en la segunda pieza (2) es a ras de una superficie para que se pueda situar el tope (9) fácilmente. También es posible entrarlo por un orificio (10) o realizar un rebaje en la segunda pieza (2). As can be seen in the figures, the joining of the pieces (1,2) is made by placing the recess (4) facing the first part (5) of the box (3) and the movement of the recess downwards, towards the second part (6). Thus the teeth (7,8) mesh and it is not possible to extract the recess (4) from the box (3) except upwards. Once the recess (4) has been placed in the second part (6), a stop (9) or plug can be placed in the first part (5) in such a way that it prevents the return movement. Preferably, the location of the recess (4) in the second piece (2) is flush with a surface so that the stop (9) can be easily located. It is also possible to enter it through a hole (10) or make a recess in the second piece (2).
Esto implica que la unión está optimizada para resistir fuerzas en la dirección de la primera parte (5) hacia la segunda parte (6). Por lo tanto, está especialmente destinado a ser esa dirección la correspondiente a la gravedad. Es decir, la primera pieza (1) correspondería a una columna y poseería la caja (3) en un lateral, para conexión con una viga o similar con un entrante (4) en su extremo (figura 1). Sin embargo, el tope (9) asegura la resistencia en cualquier dirección. This implies that the joint is optimized to resist forces in the direction of the first part (5) towards the second part (6). Therefore, it is especially destined to be that direction corresponding to gravity. That is, the first piece (1) would correspond to a column and would have the box (3) on one side, for connection to a beam or the like with a recess (4) at its end (figure 1). However, the stop (9) ensures resistance in any direction.
En la figura 1 se aprecia una forma de unir piezas (1 ,2) en ángulo, donde la caja (3) está en un costado de la primera pieza (1) y el entrante (4) en un extremo de la segunda pieza (2). En la figura 2 se muestra una forma de unir las piezas (1 ,2) con poco ángulo o incluso coaxialmente. Es aplicable a cualquier caso con gran superficie de contacto entre las piezas (1 ,2). En este caso se aprecia que cada pieza (1 ,2) posee un entrante (4) y una caja (3) en sentidos opuestos. Las correspondientes primeras partes (5) quedan enfrentadas en la posición final de montaje. En esta figura se define un orificio (10) en una o las dos piezas (1 ,2).Figure 1 shows a way of joining pieces (1,2) at an angle, where the box (3) is on one side of the first piece (1) and the recess (4) is at one end of the second piece ( 2). Figure 2 shows a way of joining the pieces (1, 2) with little angle or even coaxially. It is applicable to any case with a large contact surface between the pieces (1,2). In this case, it can be seen that each piece (1,2) has an inlet (4) and a box (3) in opposite directions. The corresponding first parts (5) face each other in the final assembly position. In this figure, a hole (10) is defined in one or both pieces (1, 2).
Este orificio (10) está alineado con ambas primeras partes (5) en la posición final. Por ese orificio (10) se introduce el tope (9) hacia la primera parte (5). En este caso, el tope (9) es más largo para taponar también este orificio (10). Se aprecia que, en la posición de montaje, ambos entrantes (4) estarán alineados para asegurar que las fuerzas se transmiten sin momentos. Esto se logra, como se muestra en la figura, definiendo escalones en la superficie de contacto de ambas piezas (1 ,2) para que la caja (3) y el entrante (4) de cada pieza (1 ,2) estén alineados. Así, cualquier estructura de madera o material similar queda perfectamente unido y resistente. Por ejemplo, puede ser una estructura de madera para un edificio. This hole (10) is aligned with both first parts (5) in the final position. Through this hole (10) the stop (9) is inserted towards the first part (5). In this case, the stop (9) is longer in order to plug this hole (10) as well. It can be seen that, in the mounting position, both recesses (4) will be aligned to ensure that the forces are transmitted without moments. This is achieved, as shown in the figure, by defining steps on the contact surface of both pieces (1,2) so that the box (3) and the recess (4) of each piece (1,2) are aligned. Thus, any structure of wood or similar material is perfectly united and resistant. For example, it can be a wooden structure for a building.
