DESCRIPCIONDESCRIPTION

Dispositivo y equipo para remodelar un producto de hormigon fresco colado en un encofrado deslizanteDevice and equipment for remodeling a fresh cast concrete product in a sliding formwork

La invencion se refiere a un dispositivo para remodelar un producto de hormigon fresco sin fraguar y a un equipo provisto de tal dispositivo. De manera mas precisa, la invencion se refiere a un dispositivo y a un equipo para realizar aberturas y agujeros en un producto de hormigon fresco colado en un encofrado deslizante.The invention relates to a device for remodeling a fresh concrete product without setting and to a device provided with such a device. More precisely, the invention relates to a device and equipment for making openings and holes in a fresh concrete product cast in a sliding formwork.

Despues de un moldeado con un encofrado deslizante, los productos de hormigon colados con frecuencia deben remodelarse de muchas formas diferentes con el fin de adecuarlos para sus objetivos de uso, porque un producto moldeado por encofrado deslizante es una pieza uniforme alargada, donde la forma de seccion transversal esta definida de acuerdo con el procedimiento de moldeado por encofrado deslizante junto con el proceso de moldeado. Las operaciones de acabado convencionales incluyen hacer varias dotaciones y agujeros en un producto de hormigon fresco colado en un encofrado deslizante para formar los necesarios agujeros, conexiones pasantes, etc.After a molding with a sliding formwork, cast concrete products often have to be remodeled in many different ways in order to adapt them to their objectives of use, because a product molded by sliding formwork is a uniform elongated piece, where the shape of Cross section is defined according to the sliding form molding process together with the molding process. Conventional finishing operations include making several endowments and holes in a fresh concrete product cast in a sliding formwork to form the necessary holes, through connections, etc.

Resulta bien conocido que la mezcla de hormigon usada en el moldeado con encofrado deslizante es bastante rlgida, para permitir que los medios de compactado para compactar la mezcla de hormigon, provistos en el equipo de moldeo por encofrado deslizante, logren un efecto de compactado suficiente en el producto formado en el molde de encofrado deslizante antes de desplazar el producto colado lejos de la zona efectiva de la maquina de colada del encofrado deslizante, a medida que el proceso de colada en el encofrado deslizante sigue avanzando. En la colada en un encofrado deslizante, se deja que un producto de hormigon fresco sin fraguar se frague en el lecho de colada sin paredes laterales u otras estructuras de soporte, en cuyo caso debe estar lo suficientemente compactado para poder conservar su forma sobre el lecho de colada a medida que el proceso de colada en encofrado deslizante sigue avanzando.It is well known that the concrete mixture used in molding with sliding formwork is quite rigid, to allow the compacting means for compacting the concrete mixture, provided in the sliding formwork molding equipment, to achieve a sufficient compacting effect in The product formed in the sliding formwork mold before moving the cast product away from the effective area of the sliding formwork casting machine, as the casting process in the sliding formwork continues to advance. When casting in a sliding formwork, a fresh concrete product without setting is allowed to set in the casting bed without side walls or other supporting structures, in which case it must be sufficiently compacted to be able to retain its shape on the bed of casting as the casting process in sliding formwork continues.

Debido a sus propiedades y al efecto de compactado provocado por la maquina de colada de encofrado deslizante, la mezcla de hormigon de un producto de hormigon fresco colado en un encofrado deslizante es muy compacta y por tanto bastante diflcil de agujerear. Ademas, los filamentos de refuerzo de los productos de hormigon colados en un encofrado deslizante con frecuencia obstruyen la formation de agujeros, debido a que los filamentos de refuerzo provistos dentro de un producto de hormigon no deberlan moverse cuando se hacen agujeros - de lo contrario el agarre de los filamentos en la mezcla de hormigon fresco se debilita.Due to its properties and the compacting effect caused by the sliding formwork casting machine, the concrete mixing of a fresh cast concrete product in a sliding formwork is very compact and therefore quite difficult to pierce. In addition, the reinforcing filaments of cast concrete products in a sliding formwork frequently obstruct the formation of holes, because the reinforcing filaments provided within a concrete product should not move when holes are made - otherwise the Grip the filaments in the fresh concrete mixture weakens.

En general, los agujeros y conexiones pasantes provistos en productos de hormigon colados en un encofrado deslizante se hacen, bien manualmente o mediante una maquina de acabado disenada para acabar un producto de hormigon colado en un encofrado deslizante.In general, through holes and connections provided in cast concrete products in a sliding formwork are made, either manually or by a finished machine designed to finish a cast concrete product in a sliding formwork.

Tales maquinas de acabado habitualmente estan provistas de una pala o un cabezal de excavation, mediante la cual la maquina hace agujeros y conexiones pasantes en puntos predeterminados del producto de hormigon colado. Convencionalmente, tales cabezales de excavacion comprenden dos mandlbulas, de las cuales, la primera mandlbula es fija y la segunda mandlbula es movil con respecto a la mandlbula fija, de modo que la punta de la mandlbula movil esta, durante el proceso de excavacion, girada hacia la mandlbula fija para desprender la mezcla de hormigon compacta y para retirarla del agujero que se ha de realizar, vease, por ejemplo, el documento FI 5.417 U1. Un problema con tales cabezales de excavacion convencionales de las maquinas de acabado regulares es que cuando se usan, es muy diflcil hacer una conexion pasante en una losa de modo que no se deje ninguna mezcla de hormigon sobre el fondo de la conexion pasante. El motivo para ello es que la punta de la mandlbula movil realiza un movimiento curvo sobre el plano de seccion transversal con respecto a su punto de sujecion y, por tanto, no es capaz de retirar toda la mezcla de hormigon del fondo del agujero creado, en particular, del area de los extremos finales del radio de movilidad de la punta de mandlbula. En la publication GB 2.336.283 A se divulga una herramienta de excavacion operada manualmente, que comprende una hoja fija y un cucharon movil con respecto a la hoja fija, cuyo cucharon esta conectado a una parte de mango de la herramienta de excavacion con una conexion pivotante. El movimiento de pivotamiento del cucharon movil esta controlado por una palanca sujeta de manera pivotante a la parte de mango. Una varilla conecta la palanca a una barra que une el cucharon movil a la parte de mango. En una disposition de acuerdo con la presente invencion, las dos mandlbulas del cabezal de excavacion estan sujetas a la estructura de soporte del cabezal de excavacion de tal manera que la mandlbula movil esta sujeta a la estructura de soporte por medio de al menos dos juntas o ejes articulados, en cuyo caso una estructura de brazo de palanca se forma entre la mandlbula de excavacion movil y las juntas o ejes articulados de la estructura de soporte. Mediante la estructura de brazo de palanca descrita, la punta de la mandlbula de excavacion movil puede desplazarse a lo largo del fondo del agujero creado sobre el nivel horizontal, es decir, sobre el nivel del fondo del agujero, claramente mejor que con las soluciones de la tecnica anterior.Such finishing machines are usually provided with a shovel or excavation head, whereby the machine makes holes and through connections at predetermined points of the cast concrete product. Conventionally, such excavation heads comprise two jaws, of which the first jaw is fixed and the second jaw is mobile with respect to the fixed jaw, so that the tip of the mobile jaw is, during the excavation process, rotated towards the fixed jaw to release the compact concrete mixture and to remove it from the hole to be made, see, for example, document FI 5.417 U1. A problem with such conventional excavation heads of regular finishing machines is that when used, it is very difficult to make a through connection in a slab so that no concrete mixture is left on the bottom of the through connection. The reason for this is that the tip of the mobile jaw performs a curved movement on the cross-sectional plane with respect to its clamping point and, therefore, is not able to remove all the concrete mixture from the bottom of the created hole, in particular, of the area of the end ends of the radius of mobility of the jaw tip. In publication GB 2,336,283 A a manually operated excavation tool is disclosed, comprising a fixed blade and a mobile bucket with respect to the fixed blade, whose bucket is connected to a handle part of the excavation tool with a connection pivoting The pivoting movement of the mobile bucket is controlled by a lever pivotally attached to the handle part. A rod connects the lever to a bar that joins the mobile bucket to the handle part. In an arrangement according to the present invention, the two jaws of the excavation head are attached to the support structure of the excavation head such that the mobile jaw is attached to the support structure by means of at least two joints or articulated axes, in which case a lever arm structure is formed between the mobile digging jaw and the articulated joints or axes of the support structure. Through the described lever arm structure, the tip of the mobile digging jaw can move along the bottom of the hole created above the horizontal level, that is, above the level of the bottom of the hole, clearly better than with the solutions of The prior art.

De este modo, mediante la disposicion de acuerdo con la invencion, la cantidad de mezcla de hormigon que se deja en el fondo del agujero creado puede reducirse notablemente, en cuyo caso, no hay necesidad de ningun medio o medidas aparte para terminar el agujero creado.Thus, by arrangement according to the invention, the amount of concrete mixture left at the bottom of the created hole can be significantly reduced, in which case, there is no need for any means or separate measures to complete the created hole. .

Por otra parte, la disposicion de acuerdo con la invencion permite la formacion de agujeros o dotacion de agujeros con fondos planos, lo que no era posible con las soluciones de la tecnica anterior.On the other hand, the arrangement according to the invention allows the formation of holes or provision of holes with flat bottoms, which was not possible with the prior art solutions.

La disposicion de acuerdo con la invencion tambien permite el reciclado de la mezcla de hormigon, primero colado en un producto de hormigon colado en un encofrado deslizante y luego retirado durante el proceso de excavacion, reutilizandolo. La mezcla de hormigon fresco retirada del producto de hormigon por el equipo de excavacion se transporta del equipo de excavacion, bien a un deposito de mezcla de hormigon de la maquina de colada de encofrado deslizante o al proceso de fabricacion de mezcla de hormigon. En consecuencia, se obtiene un ahorro tanto a nivel economico como ecologico.The arrangement according to the invention also allows recycling of the concrete mixture, first cast into a cast concrete product in a sliding formwork and then removed during the excavation process, reusing it. The fresh concrete mixture removed from the concrete product by the excavation equipment is transported from the excavation equipment, either to a concrete mixing tank of the sliding formwork casting machine or to the concrete mixing manufacturing process. Consequently, savings are obtained both economically and ecologically.

Por otra parte, la disposicion de acuerdo con la invencion tambien reduce notablemente la mano de obra necesaria para el proceso de acabado de productos de hormigon colados en un encofrado deslizante, lo que reduce aun mas los costes de fabricacion de los productos de hormigon.On the other hand, the arrangement according to the invention also significantly reduces the labor required for the finishing process of cast concrete products in a sliding formwork, which further reduces the manufacturing costs of the concrete products.

De manera mas precisa, el dispositivo de acuerdo con la invencion esta caracterizado por lo expuesto en la parte caracterizante de la reivindicacion 1 y el equipo de acuerdo con la invencion esta caracterizado por lo expuesto en la parte caracterizante de la reivindicacion 5.More precisely, the device according to the invention is characterized by what is stated in the characterizing part of claim 1 and the equipment according to the invention is characterized by what is exposed in the characterizing part of claim 5.

La invencion se describe con mas detalle a continuation, a modo de ejemplo, con referencia a los dibujos adjuntos, dondeThe invention is described in more detail below, by way of example, with reference to the attached drawings, where

la Figura 1 es una ilustracion esquematica de un cabezal de excavacion de acuerdo con la invencion, como se verla en una vista tridimensional, sin la segunda placa lateral de la estructura de soporte del cabezal de excavacion, yFigure 1 is a schematic illustration of an excavation head according to the invention, as seen in a three-dimensional view, without the second side plate of the support structure of the excavation head, and

las Figuras 2A-2C son ilustraciones esquematicas de un cabezal de excavacion de la invencion de acuerdo con la Figura 1, a medida que la mandlbula movil se desplaza hacia la mandlbula fija en las diversas etapas de la operacion de desplazamiento.Figures 2A-2C are schematic illustrations of an excavation head of the invention according to Figure 1, as the mobile jaw moves towards the fixed jaw in the various stages of the displacement operation.

La Figura 1 ilustra un cabezal de excavacion 1 de acuerdo con la invencion, incluyendo una estructura de soporte 2, una mandlbula 3 de excavacion movil, una mandlbula de excavacion fija 4 y un mecanismo de transferencia 5 que opera la mandlbula 3 de excavacion movil. En los dibujos, la segunda placa lateral de la estructura de soporte 2 del cabezal de excavacion se ha retirado para ilustrar mejor la estructura del mecanismo de transferencia 5.Figure 1 illustrates an excavation head 1 according to the invention, including a support structure 2, a mobile excavation jaw 3, a fixed excavation jaw 4 and a transfer mechanism 5 operating the mobile excavation jaw 3. In the drawings, the second side plate of the support structure 2 of the excavation head has been removed to better illustrate the structure of the transfer mechanism 5.

En la realization ilustrada en los dibujos, la mandlbula 3 de excavacion movil esta sujeta a las placas laterales de la estructura de soporte 2 del cabezal de excavacion 1 por medio de un mecanismo de transferencia 5. El mecanismo de transferencia 5 incluye dos ejes articulados 6 y 7 (el eje articulado 7 no esta ilustrado en la Figura 1) que se extienden entre las placas laterales de la estructura de soporte 2 y estan soportados por las placas laterales, unos brazos 8, 8' sujetos a un extremo de los ejes articulados 6 y 7; y en los extremos opuestos de los brazos 8, 8' y 9, 9', unos ejes articulados 10 y 11 que conectan los brazos entre si y la mandlbula 3 de excavacion movil a la estructura. Ademas, el mecanismo de transferencia 5 incluye un cilindro hidraulico 12 para generar potencia de accionamiento para la mandlbula 3 de excavacion movil.In the embodiment illustrated in the drawings, the mobile digging jaw 3 is attached to the side plates of the support structure 2 of the digging head 1 by means of a transfer mechanism 5. The transfer mechanism 5 includes two articulated axes 6 and 7 (the articulated shaft 7 is not illustrated in Figure 1) which extend between the side plates of the support structure 2 and are supported by the side plates, arms 8, 8 'attached to one end of the articulated axes 6 and 7; and at opposite ends of the arms 8, 8 'and 9, 9', articulated axes 10 and 11 that connect the arms to each other and the jaw 3 of mobile digging to the structure. In addition, the transfer mechanism 5 includes a hydraulic cylinder 12 to generate drive power for the mobile digging jaw 3.

A continuacion, la operation del cabezal de excavacion 1 de acuerdo con la invencion tal como se ilustra en los dibujos, se describe con referencia a las figuras 2A-2C.Next, the operation of excavation head 1 according to the invention as illustrated in the drawings is described with reference to Figures 2A-2C.

Cuando se usa el cabezal de excavacion 1, primero se sumergen las puntas de las mandlbulas de excavacion 3 y 4, en una position ilustrada en la Figura 2A, dentro de un producto de hormigon fresco vertido en un encofrado deslizante, a una profundidad deseada, presionandolas, por ejemplo, verticalmente hacia abajo desde el nivel de la superficie del producto. Cuando las mandlbulas de excavacion 3 y 4 estan sumergidas a la profundidad deseada dentro del producto, se detiene el movimiento de inmersion y se empieza a desplazar la mandlbula 3 de excavacion movil hacia la mandlbula de excavacion fija 4 mediante el mecanismo de transferencia 5, de conformidad con la Figura 2B.When the excavation head 1 is used, the tips of the excavation jaws 3 and 4 are first submerged, in a position illustrated in Figure 2A, into a fresh concrete product poured into a sliding formwork, at a desired depth, by pressing them, for example, vertically downwards from the level of the product surface. When the excavation jaws 3 and 4 are submerged to the desired depth within the product, the immersion movement is stopped and the mobile excavation jaw 3 begins to move towards the fixed excavation jaw 4 by the transfer mechanism 5, of in accordance with Figure 2B.

En este aspecto cabe destacar que cuando el espacio definido por las mandlbulas 3 y 4 el cabezal de excavacion 1 esta lleno de mezcla de hormigon, la mezcla de hormigon situada entre las mandlbulas obstaculiza de manera efectiva el movimiento de la mandlbula 3 hacia la mandlbula fija 4. Dicha mezcla de hormigon comprimida entre las mandlbulas ya puede retirarse del producto de hormigon levantando el cabezal de excavacion 1 hacia arriba, de modo que la mezcla de hormigon comprimida entre las mandlbulas se desprenda del producto de hormigon. La mezcla de hormigon fresco, compacta, resiste bien la compresion, pero se rompe con facilidad con las fuerzas de traccion.In this regard, it should be noted that when the space defined by the jaws 3 and 4 the excavation head 1 is filled with concrete mix, the concrete mixture between the jaws effectively hinders the movement of the jaw 3 towards the fixed jaw 4. Said compressed concrete mixture between the jaws can now be removed from the concrete product by lifting the excavation head 1 upwards, so that the compressed concrete mixture between the jaws is detached from the concrete product. The fresh, compact concrete mix resists compression well, but breaks easily with traction forces.

Cuando se ha procedido a excavar un agujero o abertura, por ejemplo, hasta una profundidad definida, la mandlbula 3 de excavacion movil puede desplazarse, durante la etapa de finalization del proceso de excavacion, a la posicion ilustrada en la Figura 2C, donde la punta de la mandlbula 3 de excavacion movil y el borde inclinado estan enWhen a hole or opening has been excavated, for example, to a defined depth, the mobile excavation jaw 3 can move, during the finalization stage of the excavation process, to the position illustrated in Figure 2C, where the tip of the mobile digging jaw 3 and the sloping edge are in

contacto con la mandlbuia de excavacion fija 4 o colocarse en las proximidades inmediatas.contact with the fixed excavation mandlbuia 4 or be placed in the immediate vicinity.

Como se aprecia mejor en las ilustraciones de las Figuras 2A-2C, la punta de la mandlbula 3 de excavacion movil durante todo el proceso de desplazamiento de la mandlbula de excavacion movil esta colocada sustancialmente al mismo nivel, es decir, en el nivel horizontal. Por tanto, toda la mezcla de hormigon sobrante puede retirarse de 5 manera efectiva del fondo del agujero formado, de modo que la calidad del agujero o abertura efectuado por el cabezal de excavacion 1 mejora de manera notable en comparacion con las soluciones de la tecnica anterior.As best seen in the illustrations of Figures 2A-2C, the tip of the mobile digging jaw 3 during the entire process of moving the mobile digging jaw is placed substantially at the same level, that is, at the horizontal level. Therefore, the entire mixture of excess concrete can be effectively removed from the bottom of the hole formed, so that the quality of the hole or opening made by the excavation head 1 improves markedly compared to the prior art solutions. .

En comparacion con un cabezal de excavacion convencional provisto de una junta o eje articulado en el cabezal de excavacion de la mandlbula de excavacion movil, la mandlbula de excavacion movil, de acuerdo con la invencion, posibilita una notable reduccion de la distancia de la punta del cabezal de excavacion desde el nivel del fondo del 10 agujero formado en posiciones extremas. Por ejemplo, en el ejemplo ilustrado en los dibujos, dicha distancia de la punta de la mandlbula de excavacion movil desde el nivel del fondo es al menos un 70-75 % mas corta en las regiones extremas del radio de movilidad que en una solucion convencional.In comparison with a conventional excavation head provided with an articulated joint or shaft in the excavation head of the mobile excavation jaw, the mobile excavation jaw, according to the invention, enables a notable reduction in the distance of the tip of the excavation head from the bottom level of the hole formed in extreme positions. For example, in the example illustrated in the drawings, said distance from the tip of the mobile digging jaw from the bottom level is at least 70-75% shorter in the extreme regions of the mobility radius than in a conventional solution .

Si bien la solucion ilustrada en los ejemplos de los dibujos solo incluye dos juntas y ejes articulados, es obvio para un experto en la materia el uso de varias juntas y/o ejes articulados en la sujecion de la mandlbula de excavacion 15 movil, en cuyo caso, el movimiento de la mandlbula de excavacion movil, en particular, en las posiciones extremas, puede acercarse mas al nivel del fondo.Although the solution illustrated in the examples of the drawings only includes two joints and articulated axes, it is obvious to one skilled in the art to use several joints and / or articulated axes in the fastening of the mobile digging jaw 15, in which In this case, the movement of the mobile digging jaw, in particular, in extreme positions, can be closer to the bottom level.

Con respecto a la realizacion ilustrada en los dibujos, tambien puede indicarse que la disposicion descrita es solo un ejemplo de realizacion de la invencion y no deberla en modo alguno interpretarse como una restriccion de la invencion. El alcance de la invencion esta restringido tan solo por las reivindicaciones adjuntas.With respect to the embodiment illustrated in the drawings, it can also be indicated that the arrangement described is only an example of embodiment of the invention and should not in any way be construed as a restriction of the invention. The scope of the invention is restricted only by the appended claims.
