ESTADO DE LA TECNICA STATE OF THE TECHNIQUE
En el estado de la técnica se conoce la solicitud de patente PCT/EP2013/053849 con patenten equivalente en Colombia No. 14187219 publicada el 12 de diciembre de 2014, que refiere a una junta de expansión para llenar un vacío de expansión entre dos piezas de losas de concreto que se usan en la construcción de pisos, especialmente en la fabricación de pisos de concreto tales como por ejemplo en pisos industriales. Evidentemente se requiere que estas juntas de expansión absorban el inevitable proceso de encogimiento del concreto y garanticen que los elementos del piso se puedan expandir o contraer, tal como ocurre por ejemplo por fluctuaciones de temperatura, lo que produce un desplazamiento horizontal de los paneles del piso unos con respecto a otros. Además, y dado el hecho de que estos pisos con frecuencia están sometidos a altas cargas, comúnmente se incluyen elementos adicionales de transferencia de carga en los mencionados perfiles de junta para garantizar que la carga vertical en un panel del piso sea transmitida al panel de piso adyacente de forma óptima y de esta forma evitar una inclinación vertical de los paneles del piso unos con respecto a otros. Sin embargo, cuando se maneja sobre una junta de expansión de este tipo, con vehículos de carga pesada tales como montacargas, que con frecuencia tienen ruedas duras Vulkollan, la presencia de estos elementos de transferencia de carga no puede evitar el daño de los rebordes circunferenciales de las losas o el daño a las ruedas, debido a la sacudida indeseable del vehículo cuando para por la separación similar a una ranura entre los elementos del piso. Esto se debe especialmente al hecho de que el perfil de la junta que constituye los bordes de los elementos del piso está hecho de acero, y por lo tanto es mucho más duro que la superficie exterior blanda circunferencial de las ruedas. Mientras, la nueva invención tiene pernos de anclaje, no requiere de doble platina inferior, se fija al concreto a través de un anclaje metálico en forma de“U” además de realizar la transferencia de carga por medio de una funda plástica y una platina metálica, mientras en el antecedente se realiza a través de la misma losa de concreto. In the state of the art, the patent application PCT / EP2013 / 053849 is known with equivalent patent in Colombia No. 14187219 published on December 12, 2014, which refers to an expansion joint to fill an expansion gap between two pieces of concrete slabs that are used in the construction of floors, especially in the manufacture of concrete floors such as for example in industrial floors. Obviously, these expansion joints are required to absorb the inevitable process of concrete shrinkage and ensure that the floor elements can expand or contract, such as occurs for example due to temperature fluctuations, which produces a horizontal displacement of the floor panels. relative to each other. Furthermore, and given the fact that these floors are frequently subjected to high loads, additional load transfer elements are commonly included in the aforementioned joint profiles to ensure that the vertical load on a floor panel is transmitted to the floor panel. adjoining in an optimal way and thus avoid a vertical inclination of the floor panels with respect to each other. However, when driving on such an expansion joint, with heavy duty vehicles such as forklifts, which often have hard Vulkollan wheels, the presence of these Load transfer elements cannot prevent damage to the circumferential flanges of the slabs or damage to the wheels, due to the undesirable shaking of the vehicle when stopping by the slot-like separation between the floor elements. This is especially due to the fact that the joint profile that constitutes the edges of the floor elements is made of steel, and is therefore much harder than the circumferential soft outer surface of the wheels. Meanwhile, the new invention has anchor bolts, it does not require a double bottom plate, it is fixed to the concrete through a metallic anchor in the shape of a "U" in addition to carrying out the load transfer by means of a plastic sleeve and a metallic plate. , while in the foregoing it is done through the same concrete slab.

Por su parte, en la nueva invención la parte inferior de la junta es completamente recta y no cuenta con orificios como el antecedente, tiene pernos de anclaje sobre una superficie ondulada, además realiza la transferencia de carga a través de la funda plástica y platina metálica. There is also the patent application No. KR101431634 published on August 20, 2014, which refers to a double waveform sliding type expansion joint apparatus to prevent a crack that forms between the concrete structures of a road and an underpass to prevent breakage between the concrete structures and a finger part due to load bearing, and guides the moisture introduced from the concrete structures to a drainage hole to prevent breakage of the joints between the concrete structures due to the ebb of moisture. The dual waveform slip type expansion joint apparatus for preventing a crack includes a pair of finger parts having multiple waveform first fingers formed on each of the inner sides; a plate formed on the underside of each of the finger portions to join each of the finger portions; a load bearing plate formed on the underside of the plate, and with multiple holes formed on an inner side; and a support part connected to the parts of the fingers and the load-bearing plate, wherein the back flow of moisture is prevented by the holes formed in the load-bearing plate to prevent deterioration of the structures of concrete and the joint gap between concrete structures and a finishing material, the finger parts and the load-bearing plate are extended in the vertical direction to minimize the rate of breakage and noise due to the reduction of vibration, and a second waveform finger on the load-bearing plate formed in the finger parts is supported by the first waveform fingers and the plate at the bottom of the first waveform fingers waveform to prevent breakage in the finishing material attached to the parts of the fingers. For its part, in the new invention the lower part of the joint is completely straight and does not have holes like the previous one, it has anchor bolts on a wavy surface, it also transfers the load through the plastic sleeve and metal plate. .

La solicitud también se refiere a un método para unir dos losas de piso (300, 400) hechas de material moldeable. Mientras, la nueva invención es fabricada en materiales metálicos y su cuerpo superior es ondulado y el inferior es recto a diferencia del antecedente que presenta una estructura trapeizoidal. In the state of the art, there is patent application No. WO2017072409 published April 5, 2017, which describes an apparatus (100) for joining two floor slabs (300, 400) made of mouldable material, where: - the apparatus (100) comprises a first strip (1 1 1), a second strip (1 12) and a dividing plate (120); • - the first strip (1 1 1) and the second strip (1 12) have an elongated shape; · Not the first strip (1 1 1) is provided with anchors (1 13) to anchor the first strip (1 1 1) to a slab of the first floor (300) made of moldable material; · - the second strip (1 12) is provided with anchors (1 13) to anchor the second strip (1 12) to a slab of the second floor (400) made of moldable material; · - the divider plate (120) has an elongated shape; · - the height of the dividing plate (120) is greater than the height of the first strip (1 1 1) or the second strip (1 12); - - the first strip (1 1 1) and the second strip (1 12) are provided with openings (1 15) to receive fixings (1 16) through the openings (1 15) to fix the first strip (1 1 1) with the second strip (1 12); and · - the dividing plate (120) is adjustably clamped between the first strip (1 1 1) and the second strip (1 12) to allow adjustment of the vertical position of the dividing plate (120) relative to the first strip (1 1 1) and second strip (1 12). The request also refers to a method of joining two floor slabs (300, 400) made of castable material. Meanwhile, the new invention is manufactured in metallic materials and its upper body is wavy and the lower body is straight, unlike the previous one, which has a trapezoidal structure.
Así como es conocida la solución con juntas cuya división superior en las placas es ondulada, como las solicitudes de patente PCT/EP2013/053849 y la solicitud No. KR101431634 mencionadas; no existe una nueva solución con una distribución de carga en la parte inferior que no sea ondulada como lo propone la nueva invención; ya que la nueva invención propone una distribución de carga inferior perpendicular compartida, donde la carga se distribuye trasversal con platina compartida entre placas de concreto cubiertas por fundas plásticas, y no solo por contacto lateral entre juntas como los antecedentes conocidos. Por otro lado, la nueva invención tiene pernos plásticos colapsibles para cambios de juntas en placas a las que están unidas, que se pueden separar sin romper la placa; a diferencia de las uniones conocidas que son soldadas o con tornillos metálicos que no se pueden separar a no ser de romper la placa. Just as the solution with gaskets whose upper division in the plates is wavy is known, such as the patent applications PCT / EP2013 / 053849 and application No. KR101431634 mentioned; There is no new solution with a load distribution in the lower part that is not wavy as proposed by the new invention; since the new invention proposes a shared perpendicular lower load distribution, where the load is distributed transversely with a shared plate between concrete plates covered by plastic covers, and not only by lateral contact between joints as the known antecedents. On the other hand, the new invention has collapsible plastic bolts for joint changes in plates to which they are attached, which can be separated without breaking the plate; Unlike the known joints that are welded or with metal screws that cannot be separated unless the plate is broken.
Como soluciones anteriores de la misma invención se propuso una junta con dovelas y platinas de transferencia de carga, donde la determinación de altura de la placa de concreto se propuso con placas rígidas de nivelación paralelas divididas y compartidas por una platina ondulada de junta superior; pero dicha solución tiene el inconveniente que debido a que las placas de nivelación tienen una división transversal, las piedras, la arena o el hormigón se aloja en dicha división externa cuando se ejecuta la junta y no permite la flexión entre placas de concreto en la sección de contacto externa, por lo que dicha solución es rígida y deteriora las placas de concreto juntadas, no permite la protección de los bordes de dilatación de la losa y no permitir transferencia de carga o movimiento entre dos losas de concreto. As previous solutions of the same invention, a joint with voussoirs and load transfer plates was proposed, where the determination of the height of the concrete plate was proposed with rigid parallel leveling plates divided and shared by an upper joint corrugated plate; but said solution has the drawback that because the leveling plates have a transverse division, the stones, sand or concrete lodge in said external division when the joint is executed and does not allow bending between concrete plates in the section of external contact, so that this solution is rigid and deteriorates the joined concrete slabs, does not allow the protection of the expansion edges of the slab and does not allow load transfer or movement between two concrete slabs.
De igual manera, en los antecedentes previos, las placas de nivelación están dispuestas a cada costado de la base donde se encuentran las dovelas y platinas de transferencia, donde existe un espacio interno en el que el hormigón no accede y no se fragua el concreto de la placa; por lo que el concreto no es distribuido de manera uniforme internamente. Para solucionar esta falencia técnica la nueva invención tiene muescas de acceso del concreto en su intermedio entre la unión de la sección ondulada y la funda plástica en un costado, y en el costado opuesto no existe ningún obstáculo entre las placas de transferencia y la sección superior, demás se eliminan las placas de nivelación a cada lado y propone una pestaña de la misma sección inferior con espacio entre la dovela con sus muescas de acceso de hormigón eliminando así el riesgo de vacío a lo largo de la junta. In the same way, in the previous antecedents, the leveling plates are arranged on each side of the base where the segments and transfer plates are located, where there is an internal space in which the concrete does not access and the concrete does not set. the plate; so the concrete is not evenly distributed internally. To solve this technical flaw, the new invention has concrete access notches in its intermediate between the union of the corrugated section and the plastic sleeve on one side, and on the opposite side there is no obstacle between the transfer plates and the upper section, others are eliminated the leveling plates to each side and proposes a flange of the same lower section with space between the segment with its concrete access notches, thus eliminating the risk of vacuum along the joint.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La junta preformada de transferencia de carga es una junta preformada para protección de filos de dilatación principalmente, que se compone de una base inferior de transferencia de carga transversal con platinas compartidas que se insertan en fundas plásticas que a su vez están incrustadas en una de las placas como se describe a continuación: The preformed load transfer joint is a preformed joint for protection of expansion edges mainly, which consists of a lower transverse load transfer base with shared plates that are inserted in plastic sleeves that are in turn embedded in one of the plates as described below:

La junta previene el deterioro de los filos de las juntas de dilatación de las losas, causados por los movimientos sobre las placas de concreto de las ruedas de montacargas, camiones y tráfico en general. Esta junta permite la transferencia de carga entre las losas de concreto a través de fundas (8) plásticas y platinas (9) metálicas que tienen una holgura de recepción de carga por alineación entre placas (9) y fundas (8) de forma transversal. The joint prevents the deterioration of the edges of the expansion joints of the slabs, caused by movements on the concrete plates of the wheels of forklifts, trucks and traffic in general. This joint allows the transfer of load between the concrete slabs through plastic sleeves (8) and metal plates (9) that have a load receiving clearance by alignment between plates (9) and sleeves (8) transversely.
Así mismo, permite el movimiento de las placas de concreto, ya que por acción de la funda (8) receptora de la platina (9) metálica permite el libre movimiento horizontal y vertical de las losas de concreto porque existe una holgura entre la funda (8) y la platina (9); donde la junta sirve para losas en exterior o interior y cualquier tipo de losa en concreto. Likewise, it allows the movement of the concrete slabs, since by the action of the sleeve (8) that receives the metal plate (9), it allows free horizontal and vertical movement of the concrete slabs because there is a gap between the sleeve ( 8) and the platen (9); where the joint is used for exterior or interior slabs and any type of concrete slab.
La parte superior (1 1 ) de la junta (10) preformada con transferencia de carga se compone de dos platinas onduladas (1 ) metálicas dispuestas paralelamente una frente a la otra, formando un espacio ondulado de separación entre ellas para cada placa de concreto, dispuestas paralelamente una frente a la otra con distancia para contracción y distención de las placas de concreto, donde unidas dichas platinas onduladas (1 ) están unidas con un perno (3) colapsible plástico que atraviesa un orificio (2) y se ajusta con tuerca (4) colapsible también. Cada platina ondulada (1 ) cuenta en medio de sus caras con orificios circulares (2) perpendiculares enfrentados donde se ubica un perno (3) colapsible plástico encargado de la sujeción de las platinas onduladas (1 ), que atraviesan y se ajustan a las caras externas de las platinas onduladas (1 ) por la acción de tuercas (4) colapsibles dispuestas a inicio y fin del perno (3) colapsible manteniendo las platinas onduladas (1 ) a determinada distancia permitiendo la contracción y distención de las placas de concreto. The upper part (1 1) of the preformed joint (10) with load transfer is made up of two corrugated metal plates (1) arranged parallel to each other, forming a corrugated space separating them for each concrete slab, arranged in parallel one in front of the other with distance for contraction and relaxation of the concrete plates, where said corrugated plates (1) are joined together with a plastic collapsible bolt (3) that passes through a hole (2) and is adjusted with a nut ( 4) collapsible too. Each corrugated plate (1) has circular holes (2) facing each other in the middle of its faces, where a plastic collapsible bolt (3) is located in charge of holding the corrugated plates (1), which pass through and adjust to the faces external parts of the corrugated plates (1) by the action of collapsible nuts (4) arranged at the beginning and end of the collapsible bolt (3), keeping the corrugated plates (1) at a certain distance allowing the contraction and relaxation of the concrete plates.
En las protuberancias (12) que se forman en la cara exterior de las platinas onduladas (1 ) se ubica en un anclaje en forma de "U" (5) metálico que conecta dos protuberancias (12) seguidas en la cara exterior de las platinas onduladas (1 ), el anclaje en forma de "U" (5) permite un mayor agarre en cada extremo de la losa de concreto fundida lo cual evita el desprendimiento entre la junta (10) y la losa de concreto. De esta manera, las platinas onduladas (1 ) tiene protuberancias (12) con en un anclaje en forma de "U" (5) metálico que conecta dos protuberancias (12) seguidas en la cara exterior de las platinas onduladas (1 ), donde el anclaje en forma de "U" (5) está fundido sólo en parte superior (1 1 ) de la junta (10) y el concreto; pero el anclaje en forma de "U" (5) metálico y no está unido a la base inferior (13), lo que garantiza la independencia de la trasferencia de carga en las platinas inferiores (9) y su contacto con el concreto y la funda (8). In the protrusions (12) that are formed on the outer face of the corrugated plates (1) it is located in a metallic "U" -shaped anchor (5) that connects two protrusions (12) in a row on the outer face of the plates. corrugated (1), the "U" shaped anchor (5) allows a greater grip on each end of the cast concrete slab which prevents detachment between the joint (10) and the concrete slab. In this way, the corrugated plates (1) have protrusions (12) with a metallic "U" shaped anchor (5) that connects two protrusions (12) in a row on the outer face of the corrugated plates (1), where the "U" shaped anchor (5) is cast only in the upper part (1 1) of the joint (10) and the concrete; but the anchor in the form of a "U" (5) metallic and is not attached to the lower base (13), which guarantees the independence of the load transfer in the lower plates (9) and its contact with the concrete and the cover (8).
Las platinas onduladas (1 ) de parte superior (1 1 ) de la junta (10) se encuentran unidas en su parte inferior a pestaña superior (6) con muescas (19) de vaciado de hormigón que conecta la parte superior (1 1 ) y la parte inferior (13) de la junta (10). Cada de una de las muescas (19) son colineales con la trayectoria de la lámina ondulada (1 ) en el costado opuesto (20) de la pestaña (6) de la parte inferior (13), con la mitad de la platina (9) cubierta con concreto entre la pestaña (6) y la platina (9). En otra versión de la invención, las muescas (19) son colineales con la trayectoria de la lámina ondulada (1 ) en el costado opuesto (20) de la pestaña (6) de la parte inferior (13), con la funda (8) cubierta con concreto entre la pestaña (6) y la funda (8). The corrugated plates (1) of the upper part (1 1) of the joint (10) are connected in their lower part to the upper flange (6) with notches (19) for casting concrete that connect the upper part (1 1) and the lower part (13) of the gasket (10). Each of the notches (19) are collinear with the path of the corrugated sheet (1) on the opposite side (20) of the flange (6) of the lower part (13), with the middle of the platen (9 ) covered with concrete between the flange (6) and the plate (9). In another version of the invention, the notches (19) are collinear with the trajectory of the corrugated sheet (1) on the opposite side (20) of the flange (6) of the lower part (13), with the cover (8 ) covered with concrete between the flange (6) and the sleeve (8).
La parte superior (1 1 ) de la junta (10) tiene platinas onduladas (1 ) metálicas dispuestas paralelamente una frente a la otra con distancia para contracción y distención de las placas de concreto, unidas perpendicularmente dichas platinas onduladas (1 ) con un perno (3) colapsible que atraviesa un orificio (2) y se ajusta con tuerca (4) colapsible y unidas perpendicularmente dichas platinas onduladas (1 ) a la parte superior de la pestaña superior (6) con muescas (19). The upper part (1 1) of the joint (10) has metal corrugated plates (1) arranged in parallel one in front of the other with distance for contraction and relaxation of the concrete plates, perpendicularly joined said corrugated plates (1) with a bolt (3) collapsible that passes through a hole (2) and is fitted with a collapsible nut (4) and said corrugated plates (1) attached perpendicularly to the upper part of the upper flange (6) with notches (19).
Por su parte, la parte inferior (13) de la junta (10) se conforma por una lámina recta (7) vertical con una pestaña superior (6) con muescas (19), que determina la altura total de la junta (10) y a su vez de la losa de concreto, en su parte inferior la lámina (7) recta termina en pestaña inferior (15) con una base de apoyo (16), sirviendo este extremo de la lámina (7) recta para apoyar la junta (10) en el terreno donde se va a fundir la placa de concreto. A su vez, la lámina (7) cuenta con perforaciones longitudinales (14) en las cuales se adapta la funda (8) plástica triangular o rectangular donde se inserta media sección de una platina (9) metálica romboidal o rectangular que permite la transferencia de carga y movimiento entre placas de concreto, proporcionando a las placas de concreto juntadas una superficie continua, permitiendo movimientos diferenciales en las separaciones entre placas de concreto por su mayor superficie de contacto. For its part, the lower part (13) of the joint (10) is made up of a straight sheet (7) vertical with an upper flange (6) with notches (19), which determines the total height of the joint (10) and in turn of the concrete slab, in its lower part the straight sheet (7) ends in a lower flange (15) with a support base (16), this end of the straight sheet (7) serving to support the joint ( 10) on the ground where the concrete slab is to be cast. In turn, the sheet (7) has longitudinal perforations (14) in which the triangular or rectangular plastic sleeve (8) fits where a half section of a rhomboidal or rectangular metal plate (9) is inserted that allows the transfer of load and movement between concrete slabs, providing the joined concrete slabs with a continuous surface, allowing differential movements in the gaps between concrete slabs due to their greater contact surface.
La funda (8) realiza el aislamiento entre la platina (9) metálica de transferencia y la placa de concreto, permitiendo así el libre movimiento de las placas de concreto y se une a la lámina (7) recta con tornillo que atraviesa los orificios (17) de cada uno de los costados opuestos la funda (8) plástica. The sleeve (8) performs the isolation between the transfer metal plate (9) and the concrete plate, thus allowing the free movement of the concrete plates and joins the straight sheet (7) with a screw that passes through the holes ( 17) on each of the opposite sides the plastic sheath (8).
La base inferior (13) de transferencia de carga transversal tiene sus platinas (9) alojadas en perforaciones longitudinales (14) compartidas entre placas de concreto unidas y ajustadas en su parte central. Dichas platinas (9) comparten media sección entre placas de concreto unidas, donde cada platina (9) tiene una funda (8) plástica en un costado que se incrustada en una de las placas juntadas transversalmente. La junta de transferencia de carga, transfiere su carga con sus platinas (9), donde media sección de la platina (9) metálica tiene contacto con una de las losas de concreto y la media sección opuesta de la platina (9) tiene contacto con una funda (8) plástica con holgura dentro de la funda (8), y la parte central de la platina (9) está alojada en la perforación longitudinal (14) de la lámina (7) recta; que permite el libre movimiento horizontal y vertical de las losas de concreto. La media sección de la platina (9) tiene contacto con placas de concreto en el costado liso (21 ). The lower base (13) for transverse load transfer has its plates (9) housed in longitudinal perforations (14) shared between concrete plates united and adjusted in their central part. Said plates (9) share a half section between joined concrete plates, where each plate (9) has a plastic sleeve (8) on one side that is embedded in one of the plates joined transversely. The load transfer joint transfers its load with its plates (9), where half a section of the metal plate (9) has contact with one of the concrete slabs and the opposite half section of the plate (9) has contact with a plastic sleeve (8) with clearance within the sleeve (8), and the central part of the platen (9) is housed in the longitudinal perforation (14) of the straight sheet (7); that allows free horizontal and vertical movement of concrete slabs. The half section of the plate (9) has contact with concrete plates on the smooth side (21).
