PIEZA DE UNIÓN PARA TRAMOS DE BANDEJA PORTACABLES DE REJILLA Y TRAMO DE BANDEJA PORTACABLES DE REJILLA  JOINT PIECE FOR REJILLA PORTABLE TRAY TRAYS AND REJILLA PORTABLE TRAY TRAYS
Campo de la invención La presente invención se refiere a una pieza de unión para tramos de bandeja de rejilla, de las empleadas para conectar los extremos de los tramos consecutivos de las bandejas de rejilla utilizadas principalmente para soportar cables eléctricos, y a un tramo de bandeja portacables de rejilla que comprende dicha pieza. Field of the Invention The present invention relates to a connecting piece for grid tray sections, of those used to connect the ends of the consecutive sections of the grid trays mainly used to support electric cables, and to a cable tray section of grid comprising said piece.
Antecedentes de la invención Tradicionalmente para unir tramos consecutivos de bandejas portacables de rejilla se han empleado uniones atornilladas. Asimismo, también se han desarrollado en la técnica anterior numerosos sistemas que sirven para conectar tramos consecutivos de bandejas de rejilla que evitan el empleo de dichas uniones atornilladas. BACKGROUND OF THE INVENTION Traditionally, to connect consecutive sections of grid cable trays, screw connections have been used. Likewise, numerous systems have also been developed in the prior art that serve to connect consecutive sections of grid trays that prevent the use of said screwed joints.
El documento ES 2093949 T3 se refiere a un tramo de camino de cables en forma de bandeja o canaleta constituido por un módulo asimétrico que presenta dos extremidades complementarias que forman cada una un órgano de acoplamiento por encaje reversible, estando constituido un primer órgano de acoplamiento por al menos una eclisa o pieza de empalme cuya extremidad próxima está soldada a dicha bandeja y cuya extremidad alejada está provista de una uña de acoplamiento, estando formado el segundo órgano de acoplamiento en al menos una parte de dicha bandeja y siendo susceptible de acoger dicha uña de acoplamiento. Esta propuesta presenta la desventaja de que la pieza de empalme está soldada de manera permanente a la bandeja de rejilla. Document ES 2093949 T3 refers to a section of cable path in the form of a tray or gutter constituted by an asymmetric module that has two complementary ends that each form a coupling element by reversible fit, a first coupling element being constituted by at least one plate or splice piece whose proximal end is welded to said tray and whose remote end is provided with a coupling nail, the second coupling member being formed in at least a part of said tray and being able to accommodate said nail of coupling. This proposal has the disadvantage that the splice piece is permanently welded to the grid tray.
El documento ES 2159099 T3 describe una brida de carriles para unir secciones de soportes para cables, dividida longitudinalmente en dos ramas, contando cada rama con medios de armado que le permiten fijarse en posición de forma inamovible en la zona del extremo de una primera sección y en la zona del extremo de una segunda sección, respectivamente. Los medios de armado de la primera rama son independientes de los de la segunda rama y permiten el armado de la brida solamente con la primera sección. Los medios de armado de la segunda rama en la segunda sección incluyen al menos un medio de enganche elástico listo para cooperar con un alambre transversal de la segunda sección después del armado de las dos secciones. Document ES 2159099 T3 describes a rail flange for joining sections of cable supports, divided longitudinally into two branches, each branch having arming means that allow it to be fixed in an immovable position in the area of the end of a first section and in the end zone of a second section, respectively. The means of assembly of the first branch are independent of those of the second branch and allow the assembly of the flange only with the first section. The assembling means of the second branch in the second section include at least one elastic coupling means ready to cooperate with a transverse wire of the second section after the assembly of the two sections.
El documento ES 2066167 T3 describe una brida para camino de cable de hilos soldados del tipo que incluye, en saliente, por lo menos dos lengüetas plegables, que están alargadas longitudinalmente, a distancia una de otra, y cada una de las cuales es apropiada para su sujeción por engaste sobre un hilo transversal de uno de los dos segmentos de camino de cable que se han de acoplar a tope, en la que cada una de las lengüetas plegables que presenta se sitúa a la altura de un vaciamiento apropiado para su doblamiento. La brida de esta invención necesita un destornillador o un útil específico para facilitar su colocación. Document ES 2066167 T3 describes a cable flange for welded wires of the type that includes, in projection, at least two folding tabs, which are longitudinally elongated, at a distance from each other, and each of which is suitable for clamping by crimping on a transverse thread of one of the two segments of cable path that must be fully coupled, in which each of the folding tongues that it presents is located at the height of an appropriate emptying for bending. The flange of this invention requires a screwdriver or a specific tool to facilitate its placement.
En el documento FR 2208219 A, referido a un dispositivo de ensamblaje para tramos de caminos de cables, se describe un dispositivo que comprende lateralmente al menos dos piezas de empalme rígidas en su parte central y elásticas en sus partes extremas, situadas entre dos elementos longitudinales de dos tramos de caminos de cables de modo que cada uno de sus extremos se acopla sobre un hilo transversal de cada uno de los dos tramos de caminos de cables. El dispositivo de esta invención también necesita un útil para facilitar su colocación. In document FR 2208219 A, referring to an assembly device for cable path sections, a device is described which comprises at least two rigid splice pieces in their central part and elastic in their end parts, located between two longitudinal elements of two sections of cable paths so that each of its ends is coupled on a transverse thread of each of the two sections of cable paths. The device of this invention also needs a tool to facilitate its placement.
El documento ES 2122829 A1 , referido a una mordaza para unión o ensamblado de tramos o ramales de caminos de cables dispuesto extremo con extremo, describe una pieza constituida por una banda metálica con una parte central rígida y dos zonas de extremidad elásticas provistas de un doblez de fijación para aplicarse alrededor de un alambre metálico transversal de un tramo del camino de cables, que comprende al menos un doblez longitudinal apto para entrar en contacto sobre dos alambres longitudinales en prolongación uno del otro, que pertenecen a los dos tramos de camino de cables, comprendiendo este doblez longitudinal dos tramos distintos que tienen líneas de abertura orientadas en sentidos opuestos, una hacia el interior del camino de cables, y la otra hacia el exterior del camino de cables. Esta mordaza necesita un útil para alcanzar su posición de bloqueo. Document ES 2122829 A1, referring to a jaw for joining or assembling sections or branches of cable paths arranged end to end, describes a piece consisting of a metal band with a rigid central part and two elastic end areas provided with a fold for fastening to be applied around a transverse metal wire of a section of the cable path, which comprises at least one longitudinal fold suitable for contacting two longitudinal wires extending from one another, which belong to the two cable path sections , this longitudinal fold comprising two different sections having opening lines oriented in opposite directions, one towards the inside of the cable path, and the other towards the outside of the cable path. This jaw needs a tool to reach its locked position.
Aunque muchas de estas propuestas de la técnica anterior no emplean partes atornilladas, normalmente necesitan un útil o herramienta para proceder a su montaje sobre las bandejas de rejilla, como se ha indicado anteriormente. Although many of these prior art proposals do not employ bolted parts, they usually need a tool or tool to be mounted on the grid trays, as indicated above.
Por otro lado, resulta muy habitual tener que cortar tramos de bandeja de rejilla en obra para lograr las longitudes deseadas. Al realizar el corte de las varillas longitudinales de la bandeja, dicho corte no resulta tan limpio como en las bandejas que vienen de fábrica, y resulta muy difícil enrasar los extremos de las varillas longitudinales cortadas con las correspondientes varillas transversales. Las piezas de unión de la técnica anterior están previstas para que, al montarse sobre dos tramos de bandejas de rejilla, exista un hueco fijo entre las dos varillas transversales adyacentes (una correspondiente a cada tramo), o bien para que no haya hueco entre dichas varillas transversales adyacentes, que estarían así en contacto. Por tanto, cuando es necesario montar un tramo cortado en obra, debido a que las varillas longitudinales no están enrasadas con las transversales, muchas de las piezas de unión de la técnica anterior no pueden montarse, al haber una separación entre varillas transversales mayor de la prevista. On the other hand, it is very common to have to cut sections of grid tray on site to achieve the desired lengths. When cutting the longitudinal rods of the tray, said cutting is not as clean as in the trays that come from the factory, and it is very difficult to flush the ends of the longitudinal rods cut with the corresponding transverse rods. The connecting pieces of the prior art are provided so that, when mounted on two sections of grid trays, there is a fixed gap between the two adjacent transverse rods (one corresponding to each section), or so that there is no gap between said adjacent transverse rods, which would thus be in contact. Therefore, when it is necessary to mount a section cut on site, because the longitudinal rods are not flush with the transverse ones, many of the connecting pieces of the prior art cannot be mounted, since there is a separation between transverse rods greater than the planned.
Sumario de la invención El objeto de la presente invención es proporcionar una pieza de unión para tramos de bandejas de rejilla que permita el montaje de forma manual (sin herramientas) por parte del instalador, y que permita su utilización cuando alguno de los tramos de bandeja de rejilla a unir haya tenido que cortarse en obra. SUMMARY OF THE INVENTION The object of the present invention is to provide a connecting piece for sections of grid trays that allows assembly by hand (without tools) by the installer, and that allows its use when any of the tray sections of grid to join had to be cut in work.
La invención proporciona una pieza de unión para tramos de bandeja de rejilla, estando constituidos los tramos de bandeja de rejilla por varillas longitudinales y varillas transversales unidas entre sí, que consiste en una placa provista de extremos susceptibles de acoplarse a varillas transversales de la bandeja de rejilla, siendo la altura de los extremos menor que la distancia entre las dos varillas longitudinales consecutivas de la bandeja de rejilla entre las que se aloja la pieza de unión, de tal modo que uno de sus extremos comprende dos prolongaciones curvadas hacia el mismo lado y, entre ellas, una prolongación curvada hacia el lado contrario, caracterizada porque el otro extremo de la pieza comprende una zona ondulada con al menos dos semiondas, cada una de las cuales es susceptible de alojar una varilla transversal de la bandeja de rejilla. The invention provides a connecting piece for grid tray sections, the grid tray sections being constituted by longitudinal rods and transverse rods joined together, consisting of a plate provided with ends capable of attaching to transverse rods of the tray grid, the height of the ends being less than the distance between the two consecutive longitudinal rods of the grid tray between which the connecting piece is housed, such that one of its ends comprises two curved extensions to the same side and , among them, a curved extension towards the opposite side, characterized in that the other end of the piece comprises a corrugated area with at least two half-waves, each of which is capable of accommodating a transverse rod of the grid tray.
La invención también proporciona un tramo de bandeja portacables, que comprende varillas longitudinales y varillas transversales unidas entre sí, teniendo las varillas transversales forma de U, de modo que forman una base y dos laterales, con varillas longitudinales situadas sobre la base y los laterales de la bandeja, respectivamente, que comprende adicionalmente al menos una pieza de unión para tramos de bandeja de rejilla, situada entre dos varillas longitudinales consecutivas y acoplada a dos varillas transversales consecutivas, una de ellas extrema y la otra interior, de modo que el extremo de la pieza que comprende dos prolongaciones curvadas hacia el mismo lado y, entre ellas, una prolongación curvada hacia el lado contrario está acoplado sobre la varilla transversal interior, y el extremo con la zona ondulada está acoplado sobre la varilla transversal extrema. Mediante esta configuración del objeto de la invención se logra una unión segura entre dos tramos consecutivos de bandejas de rejilla que permite ampliar la distancia entre las varillas transversales adyacentes. The invention also provides a section of cable tray, comprising longitudinal rods and transverse rods joined together, having the U-shaped transverse rods, so that they form a base and two sides, with longitudinal rods located on the base and sides of the tray, respectively, which additionally comprises at least one connecting piece for grid tray sections, located between two consecutive longitudinal rods and coupled to two consecutive transverse rods, one of them extreme and the other inner, so that the end of the piece comprising two extensions curved to the same side and, among them, a curved extension to the opposite side is coupled on the inner transverse rod, and the end with the corrugated zone is coupled on the extreme transverse rod. By means of this configuration of the object of the invention, a secure connection is achieved between two consecutive sections of grid trays which allows the distance between adjacent transverse rods to be extended.
Otras ventajas de la invención serían las siguientes: - Garantiza la continuidad eléctrica entre tramos de bandejas, de la misma forma que lo hace la unión atornillada. Other advantages of the invention would be the following: - Guarantees the electrical continuity between trays, in the same way as the screw connection.
- Garantiza la carga máxima entre tramos de bandejas, de la misma forma que lo hace la unión atornillada. - Guarantees the maximum load between sections of trays, in the same way as the bolted joint.
- Garantiza la integridad del montaje, sin posibilidad de "desmontaje" accidental del sistema posteriormente a la carga, y/o a la deformación de las bandejas en caso que la hubiese. - Guarantees the integrity of the assembly, without the possibility of accidental "disassembly" of the system after loading, and / or deformation of the trays if any.

Descripción detallada de la invención Las figuras 1 a 5 son varias vistas de la pieza 1 de unión para tramos 2 de bandeja de rejilla de la invención. DETAILED DESCRIPTION OF THE INVENTION Figures 1 to 5 are several views of the connecting piece 1 for sections 2 of grid tray of the invention.
En las figuras 6 a 25 se observan piezas 1 de unión y tramos 2 de bandejas portacables de rejilla. Dichas bandejas están constituidas por varias varillas metálicas longitudinales 3, 3', 3" y transversales 4, 4', 4" unidas entre sí, teniendo las varillas transversales 4, 4', 4" forma de U, de modo que forman una base 15 y dos laterales o costados 14, con algunas varillas longitudinales 3' situadas sobre la base 15 de la bandeja y algunas varillas longitudinales 3, 3" situadas sobre los laterales 14 de la bandeja. Figures 6 to 25 show connecting pieces 1 and sections 2 of grid cable trays. Said trays are constituted by several longitudinal metal rods 3, 3 ', 3 "and transverse 4, 4', 4" joined together, the transverse rods 4, 4 ', 4 "being U-shaped, so that they form a base 15 and two sides or sides 14, with some longitudinal rods 3 'located on the base 15 of the tray and some longitudinal rods 3, 3 "located on the sides 14 of the tray.
En las figuras 1 a 5 se observa que la pieza 1 de unión de la invención consiste en una placa provista de extremos susceptibles de acoplarse a varillas transversales 4, 4', 4" de bandejas de rejilla como las representadas en las figuras 6 a 25. In Figures 1 to 5 it can be seen that the connecting piece 1 of the invention consists of a plate provided with ends capable of being coupled to transverse rods 4, 4 ', 4 "of grid trays as those shown in Figures 6 to 25 .
En uno de los extremos de la pieza 1 de unión hay dos prolongaciones 5 con forma de patillas o lengüetas curvadas hacia el mismo lado y, entre ellas, una prolongación 6 con forma similar pero curvada hacia el lado contrario. En el otro extremo de la pieza hay una zona ondulada 7 con al menos dos semiondas 8, cada una de las cuales es susceptible de alojar una varilla transversal 4, 4', 4" de la bandeja de rejilla. At one end of the connecting piece 1 there are two extensions 5 in the form of pins or tongues curved to the same side and, among them, an extension 6 with a similar shape but curved to the opposite side. At the other end of the piece there is a corrugated zone 7 with at least two half-waves 8, each of which is capable of accommodating a transverse rod 4, 4 ', 4 "of the grid tray.
En la realización mostrada en las figuras 1 a 5 la zona ondulada 7 de uno de los extremos de la pieza 1 comprende tres semiondas, 8 como se aprecia mejor en la vista en planta de la figura 4. In the embodiment shown in Figures 1 to 5, the undulating area 7 of one of the ends of part 1 comprises three half-waves, 8 as best seen in the plan view of Figure 4.
En dicha realización se observa también que el extremo provisto de la zona ondulada 7 comprende adicionalmente una prolongación 9 con forma de placa doblada, y que la prolongación 9 con forma de placa doblada tiene su línea 10 de doblado próxima a su borde extremo libre 11. In said embodiment it is also observed that the end provided with the undulating area 7 additionally comprises a bent plate-shaped extension 9, and that the bent plate-shaped extension 9 has its bending line 10 close to its free end edge 11.
En la realización de dichas figuras 1 a 5 se observa que la parte central 12 de la pieza 1 de unión es aplanada y tiene practicados orificios pasantes 13. Las figuras 6 a la 10 muestran el montaje de la pieza 1 de unión para tramos 2 de bandeja de rejilla de las figuras 1 a 5 sobre un tramo 2 de bandeja de rejilla. En la figura 7 se observa que el extremo de la pieza 1 que comprende dos prolongaciones curvadas 5 hacia el mismo lado y, entre ellas, una prolongación 6 curvada hacia el lado contrario se acopla sobre una varilla transversal interior 4', situada a continuación de la varilla transversal extrema 4. Este acoplamiento se realiza con una ligera presión manual por parte del operario o instalador, sin necesidad de emplear ningún útil o herramienta. Asimismo, en las figuras 7 a 9 se observa que la prolongación 9 con forma de placa doblada situada a continuación de la zona ondulada 7 permite su sujeción por parte del usuario o instalador, con el objeto de poder acercar la pieza 1 de unión a la varilla transversal extrema 4 y de acoplarla a ella. In the embodiment of said figures 1 to 5 it can be seen that the central part 12 of the connecting piece 1 is flattened and has through holes 13. Figures 6 to 10 show the assembly of the connecting part 1 for sections 2 of grid tray of figures 1 to 5 on a section 2 of grid tray. In figure 7 it can be seen that the end of part 1 comprising two curved extensions 5 towards it side and, between them, an extension 6 curved towards the opposite side is coupled on an inner transverse rod 4 ', located next to the extreme transverse rod 4. This coupling is carried out with a slight manual pressure by the operator or installer, No need to use any tools or tools. Likewise, in Figures 7 to 9 it can be seen that the extension 9 in the form of a bent plate located next to the corrugated zone 7 allows its attachment by the user or installer, in order to be able to bring the connecting piece 1 closer to the extreme cross rod 4 and attach it to it.
En la figura 10 se observa que el extremo con la zona ondulada 7 está acoplado sobre la varilla transversal extrema 4, mediante una semionda 8 de dicha zona ondulada 7. En dicha figura 10 también se observa que la pieza 1 de unión queda montada entre dos varillas longitudinales 3 de un lateral 14 del tramo 2 de bandeja de rejilla y dos varillas transversales 4, 4' del tramo 2 de bandeja de rejilla, siendo una de éstas la varilla transversal extrema 4. In figure 10 it is observed that the end with the undulating zone 7 is coupled on the extreme transverse rod 4, by means of a half-wave 8 of said undulating area 7. In said figure 10 it is also observed that the connecting piece 1 is mounted between two longitudinal rods 3 of one side 14 of the grid tray section 2 and two transverse rods 4, 4 'of the grid tray section 2, one of these being the extreme transverse rod 4.
En las figuras 6 a la 10 también se observa que la altura de los extremos es menor que la distancia entre las dos varillas longitudinales 3 consecutivas de la bandeja de rejilla entre las que se aloja la pieza 1 de unión. Asimismo, en dichas figuras toda la pieza 1 de unión tiene una altura menor que la distancia entre las dos varillas longitudinales 3 consecutivas de la bandeja de rejilla entre las que se aloja. In figures 6 to 10 it is also observed that the height of the ends is less than the distance between the two consecutive longitudinal rods 3 of the grid tray between which the connecting piece 1 is housed. Likewise, in said figures the entire connecting piece 1 has a height less than the distance between the two consecutive longitudinal rods 3 of the grid tray between which it is housed.
En las figuras 1 1 a 15 se ilustra el montaje de una segunda pieza V de unión para tramos de bandeja de rejilla como la de las figuras 1 a 5 sobre el tramo 2 de bandeja de rejilla de las figuras 6 a 10. Esta segunda pieza V de unión se monta sobre el otro lateral 14 del tramo 2 de bandeja de rejilla, siendo su acoplamiento igual que el descrito para las figuras 6 a 10. Es de destacar que la misma pieza de unión sirve para ser colocada sobre un lateral 14 del tramo 2 de bandeja de rejilla o sobre el otro (incluso sobre la base 15 del tramo de bandeja de rejilla), por lo que no es necesario tener piezas de unión de la invención de varios tipos o configuraciones. Figures 1 1 to 15 illustrate the assembly of a second connecting piece V for grid tray sections like that of Figures 1 to 5 on the grid tray section 2 of Figures 6 to 10. This second piece Connection V is mounted on the other side 14 of the grid tray section 2, its coupling being the same as that described for Figures 6 to 10. It is noteworthy that the same connection piece serves to be placed on a side 14 of the section 2 of grid tray or on the other (even on the base 15 of the grid tray section), so it is not necessary to have connecting pieces of the invention of various types or configurations.
La figura 15 muestra un tramo 2 de bandeja portacables, que comprende varillas longitudinales 3, 3', 3" y varillas transversales 4, 4', 4" unidas entre sí, teniendo las varillas transversales 4, 4', 4" forma de U, de modo que forman una base 15 y dos laterales 14, con varillas longitudinales 3'; 3, 3" situadas sobre la base 15 y los laterales 14 de la bandeja, respectivamente, que comprende adicionalmente sobre cada lateral 14 del tramo 2 de bandeja portacables una pieza 1 , 1 ' de unión para tramos de bandeja de rejilla, situada entre dos varillas longitudinales (3, 3; 3", 3") consecutivas y acoplada a dos varillas transversales 4, 4' consecutivas, una de ellas extrema y la otra interior, de modo que el extremo de la pieza 1 , V que comprende dos prolongaciones 5 curvadas hacia el mismo lado y, entre ellas, una prolongación 6 curvada hacia el lado contrario está acoplado sobre la varilla transversal interior 4', y el extremo con la zona ondulada 7 está acoplado sobre la varilla transversal extrema 4. Figure 15 shows a section 2 of cable tray, comprising longitudinal rods 3, 3 ', 3 "and transverse rods 4, 4', 4" joined together, having the transverse rods 4, 4 ', 4 "U-shaped , so that they form a base 15 and two sides 14, with longitudinal rods 3 '; 3, 3 "located on the base 15 and the sides 14 of the tray, respectively, which additionally comprises on each side 14 of the tray section 2 1, 1 'connecting piece for grid tray sections, located between two consecutive longitudinal rods (3, 3; 3 ", 3") and coupled to two consecutive transverse rods 4, 4', one of them extreme and the other interior, so that the end of the piece 1, V comprising two extensions 5 curved to the same side and, between they, an extension 6 curved towards the opposite side is coupled on the inner transverse rod 4 ', and the end with the corrugated zone 7 is coupled on the extreme transverse rod 4.
La figura 25 muestra un tramo 2 de bandeja de rejilla provisto de tres piezas 1 , 1 ', 1 " de unión para tramos 2 de bandeja de rejilla de la invención, con una pieza 1 , 1 ' de unión acoplada sobre cada lateral 14 del tramo 2 de la bandeja de rejilla, y una pieza 1 " de unión acoplada sobre la base 15 del tramo 2 de la bandeja de rejilla. La pieza 1 " de unión acoplada sobre la base 15 (preferentemente, sobre su zona central) puede ser necesaria cuando el ancho de la bandeja así lo requiera. El tramo 2 de bandeja de rejilla de la figura 15 puede suministrarse como un conjunto premontado en fábrica que sobre uno de sus extremos presenta dos piezas 1 , 1 ' de unión para su acoplamiento con otro tramo 2' de bandeja de rejilla. Asimismo, el tramo 2 de bandeja de rejilla de la figura 25 también puede suministrarse como un conjunto premontado en fábrica que sobre uno de sus extremos presenta tres piezas 1 , 1', 1 " de unión para su acoplamiento con otro tramo 2' de bandeja de rejilla. Figure 25 shows a section 2 of grid tray provided with three pieces 1, 1 ', 1 "of connection for sections 2 of grid tray of the invention, with a piece 1, 1' of coupling coupled on each side 14 of the section 2 of the grid tray, and a connecting piece 1 "coupled on the base 15 of section 2 of the grid tray. The connecting piece 1 "coupled on the base 15 (preferably, on its central area) may be necessary when the width of the tray so requires. The grid tray section 2 of Figure 15 can be supplied as a preassembled assembly in factory which on one of its ends has two connecting pieces 1, 1 'for coupling with another section 2' of grid tray, and also the section 2 of grid tray of Figure 25 can also be supplied as a preassembled assembly in factory that on one of its ends presents three pieces 1, 1 ', 1 "of union for its coupling with another section 2' of grid tray.
En el caso de que alguna de esas piezas 1 , 1 ', 1 " de unión premontadas se deformara o deteriorara en el almacén o durante el transporte, se podría desmontar sin perjudicar la integridad del tramo 2 de bandeja de rejilla. In the event that any of these pre-assembled pieces 1, 1 ', 1 "of the joint is deformed or deteriorated in the warehouse or during transport, it could be disassembled without damaging the integrity of the grid tray section 2.
De manera alternativa, los tramos de bandeja de las figuras 15 y 25 también pueden montarse en obra de manera manual. Alternatively, the tray sections of Figures 15 and 25 can also be assembled on site manually.
En las figuras 16 a 24 se representa el montaje de dos tramos 2, 2' de bandeja de rejilla consecutivos mediante dos piezas 1 , 1 ' de unión para tramos 2, 2' de bandeja de rejilla de la invención, previamente acopladas a uno de dichos tramos 2. Figures 16 to 24 show the assembly of two consecutive sections 2, 2 'of grid tray by means of two connecting pieces 1, 1' for sections 2, 2 'of grid tray of the invention, previously coupled to one of said sections 2.
En la figura 19 se observa que la prolongación 9 con forma de placa doblada se introduce en el espacio delimitado por las varillas longitudinales 3 situadas sobre el lateral 14 del segundo tramo 2' de bandeja de rejilla, de manera que en el siguiente paso la semionda 8 adyacente a la prolongación 9 con forma de placa doblada se acopla sobre la varilla transversal extrema 4 del segundo tramo 2' de bandeja de rejilla, llegándose al conjunto montado de la figura 24. Se observa que durante el proceso de unión el tramo 2 de bandeja de rejilla con las piezas 1 , 1 ' de unión integradas se sitúa en el mismo plano de montaje que el otro tramo 2', sin necesidad de tener que recurrir a mayor espacio en su eje vertical u horizontal. En la figura 23 en planta se observa que la zona ondulada 7 situada sobre el extremo de la pieza 1 de unión que se acopla con el tramo 2' de bandeja de rejilla adyacente permite variar la distancia entre las varillas transversales 4 adyacentes de los dos tramos 2, 2' de bandeja de rejilla a unir. En efecto, dicha zona ondulada 7 puede someterse a cierta flexión, lo que hace que tenga un efecto "distanciador" que permite jugar con algunos milímetros adicionales de holgura para adaptarse a la distancia entre las varillas transversales 4 adyacentes. Esto resulta especialmente útil cuando en uno de los extremos de uno de los tramos 2, 2' de bandeja de rejilla las varillas longitudinales 3, 3', 3" han tenido que ser cortadas en obra y no se encuentran enrasadas con la varilla transversal extrema 4. La pieza 1 , V, 1 " de unión es metálica y puede fabricarse con cualquier acabado superficial. Asimismo, su configuración no contiene elementos cortantes ni aristas que puedan dañar los cables o al instalador durante el montaje. In figure 19 it is observed that the extension 9 in the form of a bent plate is introduced into the space delimited by the longitudinal rods 3 located on the side 14 of the second section 2 'of grid tray, so that in the next step the half-wave 8 adjacent to the extension 9 in the form of a bent plate is coupled on the extreme transverse rod 4 of the second section 2 'of grid tray, reaching the assembled assembly of Figure 24. It is observed that during the joining process the section 2 of Grid tray with integrated joining pieces 1, 1 'is placed in the same assembly plane as the other section 2', without having to resort to more space in its vertical or horizontal axis. In Fig. 23 in plan it is observed that the undulating zone 7 located on the end of the connecting piece 1 that is coupled with the adjacent grid tray section 2 'allows to vary the distance between the adjacent transverse rods 4 of the two sections 2, 2 'of grid tray to join. In fact, said undulating zone 7 can undergo some bending, which makes it have a "spacer" effect that allows it to play with some additional millimeters of clearance to adapt to the distance between adjacent transverse rods 4. This is especially useful when at one of the ends of one of the sections 2, 2 'of grid tray the longitudinal rods 3, 3', 3 "have had to be cut on site and are not flush with the extreme transverse rod 4. The connecting piece 1, V, 1 "is metallic and can be manufactured with any surface finish. Also, its configuration does not contain sharp elements or edges that could damage the cables or the installer during assembly.
