Abstract

The invention relates to a dismantlable joint system for metal beams that have a level upper part, characterised by the use of a main support plate (1) and a secondary support plate (2). The plates are provided with slots (3, 4) that enable different-sized standard I-profiles to be joined. For this purpose, in addition to what is mentioned above, securing clamps (5), with the corresponding screws (6), nuts (7) and washers (8), are required. The main support plate (1) is also provided with lateral flanges (10) having slots (11) that allow the height of different-sized metal profiles to be adjusted. By inserting the clamping screws (15) through the slots (11) and drill holes (14), the height of the beams can be adjusted to level the upper parts thereof. The adjusting screws (16), which are mounted in threads (21) of the main support plate, allow the height to be adjusted exactly, before firmly tightening the clamping screws (15). Furthermore, by inserting stiffening screws (18) into the drill holes (19) of the main support plate (1), the bending moments of the secondary beam (12) can be transmitted and converted into torsion in the main beam (9).

SISTEMA DE UNIÓN DESMONTABLE MEDIANTE GRAPAS PARA VIGAS METÁLICAS DE PERFIL I ENRASADAS POR LA PARTE SUPERIOR REMOVABLE JOINT SYSTEM BY STAPLES FOR METAL BEAMS OF PROFILE I FITTED BY THE TOP
SECTOR DE LA TECNICA TECHNICAL SECTOR
La presente invención se refiere a un sistema de unión desmontable de perfiles metálicos tipo i, aplicado a la fabricación y montaje de estructuras metálicas desmontables y reconfigurabies, mediante el uso de perfiles de acero estándar. The present invention relates to a removable joining system of type I metal profiles, applied to the manufacture and assembly of removable and reconfigurable metal structures, by using standard steel profiles.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En la actualidad, prácticamente todas las uniones empleadas en la fabricación de estructuras metálicas con perfiles de acero estándar, utilizan la unión por soldadura o las uniones atornilladas disicas. At present, practically all the unions used in the manufacture of metal structures with standard steel profiles, use the weld joint or the screwed disic joints.
En el primero de los casos, las uniones soldadas, presentan el gran inconveniente de que no son desmontables ni reconfigurabies; su desmontaje implica generalmente su destrucción, con ios inconvenientes que eilo conlleva. In the first case, the welded joints have the great disadvantage that they are not removable or reconfigurable; its dismantling generally implies its destruction, with the inconveniences that eilo entails.
Las uniones atornilladas clásicas, por su parte, necesitan una preparación previa de los perfiles a unir. Son necesarias operaciones que implican el soldado de placas, el rígidizado de las almas de los perfiles, el taladrado de los perfiles, etc. Este tipo de fabricación se lleva a cabo generalmente para configuraciones muy específicas, por lo que solo es util para los casos que fueron diseñados. Classic screw connections, on the other hand, need a previous preparation of the profiles to be joined. Operations involving plate welding, stiffening of profile souls, drilling of profiles, etc. are necessary. This type of manufacturing is generally carried out for very specific configurations, so it is only useful for cases that were designed.
En resumen, con las uniones empleadas actualmente en la fabricación de estructuras metálicas, la soldadura y las uniones atornilladas, no existe la posibilidad de reconfigurar la estructura aprovechando todos los componentes del sistema, incluidos ios perfiles a unir. In summary, with the unions currently used in the manufacture of metal structures, welding and bolted joints, there is no possibility of reconfiguring the structure taking advantage of all the components of the system, including the profiles to be joined.
Un sistema desmontable para perfiles metálicos tipo ), en ei cual no es necesario ningún tipo de preparación previa de los perfiles, es el que emplea grapas de unión. El uso de estas grapas como amarre de ios perfiles es frecuente en uniones de perfiles cuando estos se cruzan, mediante e! uso de una placa intermedia taladrada a medida, segun el tipo de perfil a utilizar. A removable system for metal profiles type), in which no type of pre-preparation of the profiles is necessary, is the one that uses joining clips. The use of these clips as a mooring of the profiles is frequent in profile joints when these intersect, through e! use of an intermediate plate drilled to measure, according to the type of profile to use.
Además hay que tener en cuenta que para ias uniones de los perfiles, dependiendo del diseno y del método de ejecución de la unión, se pueden conseguir distintos tipos de comportamiento resultante de la unión. Ésta puede llegar a comportarse como unión articulada, rígida o semirrígida, dependiendo del momento flector que sea capaz de transmitir. In addition, it must be taken into account that for the unions of the profiles, depending on the design and the method of execution of the union, different types of behavior resulting from the union can be achieved. It can behave as an articulated, rigid or semi-rigid joint, depending on the bending moment it is capable of transmitting.
Con el empleo de grapas, las cuales se muestran a continuación, se busca que sea posible la uniori de distintos tamaños de perfiles I estándar, mis concretamente para el caso de uniones del tipo viga-viga enrasadas por la parte superior, sin que sea necesario operaciones de preparación previas sobre ios perfiles y permitiendo que ias uniones obtenidas sean totalmente desmontables y reutilizables. La única operación necesaria a realizar, empleando sistemas de unión con grapas de fijaciort, arandelas y lomillería estándar, es ei corte de ios perfiles a la medida necesaria. Además, con el empleo del sistema de grapas propuesto, se podrá concebir de forma fácil y reversible un nudo articulado o rígido/semirrígido, según el momento flector que sea capaz de transmitir/absorber ios perfiles implicados en la unión. With the use of staples, which are shown below, it is sought that the uniori of different sizes of standard I profiles be possible, more specifically for the case of beam-beam type connections flush with the top, without it being necessary previous preparation operations on the profiles and allowing the joints obtained to be completely removable and reusable. The only necessary operation to be carried out, using joining systems with fixing clips, washers and standard lomillería, is the cutting of the profiles to the necessary extent. In addition, with the use of the proposed staple system, an articulated or rigid / semi-rigid knot can be conceived easily and reversibly, depending on the bending moment that is capable of transmitting / absorbing the profiles involved in the joint.
Actualmente existen divulgaciones de sistemas de unión desmontables para perfiles de acero estándar tipo I, como por ejemplo ES2432915B2. Sin embargo cuando se trata de vigas enrasadas por la parte superior, no se conoce ningón sistema que reúna las siguientes características: a) que no necesite preparación previa de ios perfiles a unir, b) que sea totalmente desmontable y reconfigurable, c) que los mismos elementos empleados para la unión sean válidos para diferentes tamaños de perfiles i, d) que permita regular con exactitud la altura para mantener las vigas enrasadas por la parte superior. There are currently disclosures of removable joint systems for standard type I steel profiles, such as ES2432915B2. However, when it comes to beams flush at the top, there is no known system that meets the following characteristics: a) that does not require prior preparation of the profiles to be joined, b) that is completely removable and reconfigurable, c) that the same elements used for the union are valid for different sizes of profiles i, d) that allows to regulate the height exactly to keep the beams flush with the top.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
Para dar solución a ios inconvenientes anteriormente descritos, la presente invención (Figura 1 ) consiste en el empleo de una placa soporte principal (1, ver Figura 2) y una placa soporte secundaría (2, ver Figura 3). Ambas placas estan provistas de unos rasgados (3,4) que hacen posible la unión de distintos tamaños de perfiles I estándar. Para realizar la unión de los perfiles, se necesita además de ia placa soporte principalTo solve the problems described above, the present invention (Figure 1) consists in the use of a main support plate (1, see Figure 2) and a secondary support plate (2, see Figure 3). Both plates are provided with torn ones (3,4) that make it possible to join different sizes of standard I profiles. To make the joining of the profiles, the main support plate is also required
(1) y la placa soporte secundaria (2), unas grapas de fijación (S, ver Figura 1 ) con sus tomillos (6), tuercas (7) y arandelas (8) correspondientes. Con este sistema se realizarla la unión del tipo viga-viga enrasadas por la parte superior, empleando para ello perfiles metálicos normalizados de! tipo I. (1) and the secondary support plate (2), fixing clips (S, see Figure 1) with their thymes (6), nuts (7) and corresponding washers (8). With this system the union of the beam-beam type flush at the top, using standardized metal profiles of! type I.
Los rasgados (3) en la placa soporte principal (1) y los rasgados (4) en la placa soporte secundaria (2), permiten ei ajuste de las grapas y su tornillería, en ambos lados del ala de los diferentes tamaños de perfiles a unir (ver Figura 4). The tears (3) in the main support plate (1) and the tears (4) in the secondary support plate (2), allow the adjustment of the clips and their screws, on both sides of the wing of the different sizes of profiles to join (see Figure 4).
La placa soporte principal (1 , ver Figura 2) que se amarra a la viga principal (9) está provista de unas pestañas laterales (10) que estan soldadas en el centro de ia placa mediante unas láminas delgadas (17) y estas pestañas laterales tienen unos rasgadosThe main support plate (1, see Figure 2) that is attached to the main beam (9) is provided with side flanges (10) that are welded in the center of the plate by thin sheets (17) and these side flanges they have torn
(11) , los cuales permiten regular la altura para distintos tamaños de perfiles metálicos, cuando esta placa se monta sobre la placa soporte secundaría (2) (ver Figura 5). Este montaje es posible debido a que la placa soporte secundaria (2, ver Figura 3) esta provista de unas pestañas (13), en ias cuales se han realizado unos taladros (14), los cuales permiten mediante el empleo de unos tornillos de apriete (15), tuercas (20) y arandelas (22), la ur#ri a ia placa soporte principal (1) a través de los rasgados (11). Otros tomillos de ajuste (16), los cuales van colocados en los roscados (21 ) de la placa soporte principal (1), permiten empujar las pestañas (13) de la placa soporte secundaria (2) y, como consecuencia, regular con exactitud la altura de la viga secundaria (12) respecto a la viga principal (Θ) (ver Figura 6). (11), which allow the height to be adjusted for different sizes of metal profiles, when this plate is mounted on the secondary support plate (2) (see Figure 5). This assembly is possible because the secondary support plate (2, see Figure 3) is provided with some tabs (13), in which holes (14) have been made, which allow using clamping screws (15), nuts (20) and washers (22), the ur # ri to the main support plate (1) through the tears (11). Other adjusting screws (16), which are placed on the threads (21) of the main support plate (1), allow pushing the tabs (13) of the secondary support plate (2) and, as a consequence, regulate exactly the height of the secondary beam (12) with respect to the main beam (Θ) (see Figure 6).
Cuando están la viga principal (9) y la viga secundaria (12) enrasadas con exactitud por la parte superior, se realiza el apriete de los tornillos de apriete (15), tuercas (20) y arandelas (22) (ver Figura 6). When the main beam (9) and the secondary beam (12) are flush with precision from the top, the tightening bolts (15), nuts (20) and washers (22) are tightened (see Figure 6) .
Para evitar que se produzcan esfuerzos de torsién en la viga principal (9), los esfuerzos debidos a la viga secundaria (12), son transmitidos a través de las láminas delgadas (17) de la placa soporte principal (1, ver Figura 2), las cuales se sitúan de forma centrada sobre ei alma de la viga principal (9) (ver Figura 5). Debido a que estas láminas delgadas (17) son fácilmente deformables, permiten no transmitir los momentos flectores de la viga secundaria (12) a la viga principal (9), lo que supondría esfuerzos de torsién en la viga principa! (9). Para los casos en los que si se quiere transmitir los esfuerzos de flexión de la viga secundaria (12) a la viga principal (9), se colocarían los tornillos de rigidización (18) sobre los taladros (19) de la placa soporte principal (1) (ver Figura 6). To avoid torsional stresses in the main beam (9), the forces due to the secondary beam (12) are transmitted through the thin sheets (17) of the main support plate (1, see Figure 2) , which are centered on the core of the main beam (9) (see Figure 5). Because these thin sheets (17) are easily deformable, they allow not to transmit the bending moments of the secondary beam (12) to the main beam (9), which would involve torsional stresses in the main beam! (9). For cases in which if you want to transmit the bending stresses of the secondary beam (12) to the main beam (9), the stiffening screws (18) would be placed on the holes (19) of the main support plate ( 1) (see Figure 6).

REALIZACIÓN PREFERENTE DE LA INVENCION PREFERRED EMBODIMENT OF THE INVENTION
A continuación se realiza una descripción de la realización de la invención, haciendo referencia a la numeración adoptada en ias figuras. A description of the embodiment of the invention follows, with reference to the numbering adopted in the figures.
Primero se coloca la placa soporte principal (1) bajo la viga principal (9) y se amarra la placa a ias alas del perfil empleando las correspondientes grapas (5) y su correspondiente tornilleria (6), tuercas (7) y arandelas (8) (ver Figura 7). First, the main support plate (1) is placed under the main beam (9) and the plate is tied to the wings of the profile using the corresponding clips (5) and its corresponding screws (6), nuts (7) and washers (8 ) (see Figure 7).
Para resolver dicho montaje primero se sujeta una grapa (5) con su tornilleria (6) y una vez ajustado el tamaño del ala del perfil correspondiente, se coloca debajo de la tuerca (7) la arandela (8) plana de apoyo. Todo esto con cuidado de dejar la placa soporte principa! (1) alineada con las alas del perfil y aproximando al máximo los tornillos (6) de las grapas de fijación (5) al borde del perfil. Se repite esta operación en cada uno de los rasgados (3) y una vez realizado, apretamos firmemente todos los tornillos (6). A continuación sobre la placa soporte principal (1) se montan los tornillos de ajuste (16). To solve this assembly, a clip (5) is fastened with its screws (6) and once the size of the corresponding profile wing is adjusted, the flat support washer (8) is placed under the nut (7). All this with care to leave the main support plate! (1) aligned with the wings of the profile and maximizing the screws (6) of the fixing clips (5) to the edge of the profile. This operation is repeated on each tear (3) and once done, firmly tighten all screws (6). Next, the adjustment screws (16) are mounted on the main support plate (1).
Después colocamos la placa soporte secundaria (2) bajo la viga secundaria (12) y se amarra la placa a las alas del perfil siguiendo las mismas operaciones que en el caso anterior (ver Figura 8). Then we place the secondary support plate (2) under the secondary beam (12) and the plate is tied to the wings of the profile following the same operations as in the previous case (see Figure 8).
El paso siguiente es acercar las dos vigas, con sus correspondientes placas montadas y cuando están alineados ios rasgados (11 ) de la piaca soporte principal (1), con ios taladros (14) de ia placa soporte secundaria (2) (ver Figura 5), se introducen los tornillos de apriete (15); por los taladros (14) y rasgados (11 ), pero se dejan flojos para poder con otros tomillos de ajuste (16) regular con exactitud la altura. Una vez que están la viga principal (9) y la viga secundaria (12) enrasadas con exactitud por la parte superior, se aprietan firmemente los tomillos de apriete (15) (ver Figura 6). The next step is to bring the two beams closer together, with their corresponding plates mounted and when the torn (11) of the main support plate (1) are aligned, with the holes (14) of the secondary support plate (2) (see Figure 5 ), the tightening screws (15) are introduced; by the drills (14) and torn (11), but they are left loose to be able to adjust the height exactly with other adjustment screws (16). Once the main beam (9) and the secondary beam (12) are flush with precision from the top, the clamping screws (15) are firmly tightened (see Figure 6).
Después si queremos que se transmitan los momentos Héctores de la viga secundaria (12), que se transforma en torsión sobre la viga principal (9), se introducen los tornillos de rigidización (18) sobre los taladros (19) de ia placa soporte principal (1) (ver Figura 6). Then, if we want the Hector moments of the secondary beam (12) to be transmitted, which is transformed into torsion on the main beam (9), the stiffening screws (18) are introduced on the holes (19) of the main support plate (1) (see Figure 6).
