Background of the invention

En el mercado existen diversos sistemas de anclaje de placas de encofrado utilizadas en la ejecución de pilares o pequeños muros que quedan dispuestas en posición ortogonal entre sí.In the market there are various systems of anchoring of formwork plates used in the execution of pillars or small walls that are arranged in position orthogonal to each other.

Así, podemos considerar el sistema que se basa en unas placas metálicas de encofrado, de forma general rectangular, que en uno de sus lados laterales mayores disponen de una serie de bulones soldados provistos de unos orificios pasantes, mientras que en su otro costado presentan una serie de orificios para permitir el alineamiento de las placas de encofrado en la configuración de muros al poder unirse a través de los citados bulones por medio de chavetas rectas a modo de cuña.Thus, we can consider the system that is based on some metal formwork plates, generally rectangular, which on one of its major lateral sides have a series of welded bolts provided with through holes, while on its other side they present a series of holes to allow the alignment of the formwork plates in the configuration of walls to be able to join through the aforementioned bolts through wedge straight pins.

Por otra parte, las placas metálicas de encofrado por su cara posterior presenta unos perfiles, a distinta altura, de forma general en "U" con unas pletinas inclinadas convergentes desde el extremo interno de sus alas hacia el interior, disponiendo en relación al alma de los mismos de una pluralidad de orificios pasantes alineados.Moreover, the metal formwork plates by its back face it presents some profiles, at different height, of general "U" shape with converged inclined plates from the inner end of its wings inwards, arranging in relation to their soul from a plurality of holes aligned interns.

De esta forma, en la ejecución del correspondiente pilar las placas de encofrado se adosan disponiéndose en posición ortogonal, de manera que la serie de bulones de uno de los costados de una placa de encofrado se encajan en correspondientes orificios de la pluralidad de orificios alineados a diferentes alturas de la placa adosada, materializando el anclaje por medio de respectivas chavetas curvas, a modo de cuña, de encaje en los orificios pasantes de los bufones y haciendo tope sobre las pletinas inclinadas convergentes.In this way, in the execution of corresponding pillar formwork plates are attached disposing in orthogonal position, so that the series of bolts on one side of a formwork plate fit together in corresponding holes of the plurality of holes aligned at different heights of the attached plate, materializing anchoring by means of respective curved keys, by way of wedge, lace into the through holes of jesters and making butt over converging inclined plates.

Así, la citada chaveta presenta una forma curva, a modo de cuña, esto es, de anchura creciente de un extremo al otro y de igual grosor según dota su longitud.Thus, said key has a curved shape, as a wedge, that is, of increasing width from one end to the other and of equal thickness according to its length.

--: un primer perfil de sección general en "U" con su alma curvada dotada centralmente de un saliente en "U" invertida cuya alma queda enrasada con el extremo libre de las alas del perfil, presentando las alas del perfil en "U", en relación al alma, un saliente hacia el exterior, quedando fijado el perfil de sección general en "U" a la cara externa de la placa de encofrado por el extremo libre de sus alas y por el alma de su saliente central en "U" invertida;a first profile of general "U" section with its centrally curved soul of an inverted "U" projection whose soul is flush with the free end of the profile wings, presenting the wings of the "U" profile, in relation to the soul, a projection towards the outside, the general section profile being set to "U" to the outer face of the formwork plate by the free end of its wings and by the soul of its central projection in "U" inverted

--: un cuerpo corredera definido por un segundo perfil de sección general en "U" con su alma curvada estando dotado de un corte central en sus alas prolongado hacia su alma definiendo así las alas por una pareja de brazos dotados de una prolongación lateral provista de sendos salientes y presentando, respecto de una de sus alas, una prolongación paralela y próxima al alma, estando dotadas en el espacio existente entre la prolongación y el lateral del alma de respectivos tetones enfrentados;a sliding body defined by a second general section profile in "U" with its curved soul being endowed with a central cut in its wings prolonged towards his soul thus defining the wings for a couple of arms equipped with a lateral extension provided with two outgoing and presenting, with respect to one of its wings, a parallel prolongation and close to the soul, being endowed in the space between the extension and the side of the soul of respective breasts facing each other;

--: una chaveta curva, a modo de cuña, dotada de un regruesado perimetral excepto en un pequeño tramo relativo al lado de menor radio y en proximidad al extremo de mayor anchura.a curved key, to wedge mode, equipped with a perimeter backing except in a small section relative to the side of smaller radius and in proximity to wider end.

Las alas del cuerpo corredera definido por un segundo perfil de sección general en "U" presentan una menor longitud que las alas del primer perfil de sección general en "U" que se fija a la cara externa de la placa de encofrado.The wings of the sliding body defined by a second general section profile in "U" present a smaller length than the wings of the first general section profile in "U" that attaches to the outer face of the plate formwork

Asimismo, el alma curva del cuerpo corredera definido por un segundo perfil de sección general en "U" presenta un mayor radio de curvatura que el alma curva del primer perfil de sección general en "U".Also, the curved soul of the sliding body defined by a second general section profile in "U" it has a greater radius of curvature than the first soul curve "U" general section profile.

Por otra parte, el primer perfil de sección general en "U" en relación al alma de su saliente central en "U" invertida solidario a la cara externa de la placa de encofrado presenta una serie de orificios pasantes, a través de los cuales será pasante el correspondiente bulón del costado de la placa de encofrado adosada en posición ortogonal a ella.Moreover, the first section profile general in "U" in relation to the soul of its central projection in "U" inverted integral to the outer face of the plate formwork presents a series of through holes, through the which will be the corresponding bolt on the side of the formwork plate attached orthogonal to it.

Para el montaje del sistema en una primera fase se monta la chaveta en el cuerpo corredera definido por el perfil de sección general en "U" encajando el pequeño tramo de menor grosor de su contorno entre la pareja de tetones enfrentados de la prolongación de una de sus alas y del lateral de su alma.For mounting the system in a first phase the key is mounted on the sliding body defined by the profile of general section in "U" fitting the small section of minor thickness of its contour between the pair of breasts facing the prolongation of one of its wings and the side of its soul.

En una segunda fase se monta el cuerpo corredera definido por el segundo perfil de sección en "U", que ya monta la correspondiente chaveta, respecto del primer perfil de sección en "U" solidario a la cara posterior de la correspondiente placa de encofrado encajando a presión los salientes de las alas del cuerpo corredera definido por un segundo perfil de sección en "U" tras los salientes de las alas del primer perfil de sección general en "U".In a second phase the sliding body is mounted defined by the second "U" section profile, which is already mounted the corresponding key, with respect to the first section profile in "U" integral to the back of the corresponding formwork plate snapping the wing projections of the sliding body defined by a second section profile in "U" behind the wing protrusions of the first profile of general section in "U".

De esta forma, el cuerpo corredera queda enclavado por presión, con un ajuste y presión suficiente para deslizar a lo largo del primer perfil de sección general en "U" pero sin posibilidad de liberación.In this way, the sliding body is interlocked by pressure, with sufficient adjustment and pressure to slide along the first general section profile in "U" but no possibility of release.

En el anclaje de las placas en posición ortogonal entre sí el correspondiente bufón del costado de una de las placas de encofrado es pasante por el correspondiente orificio practicado en relación al alma del saliente central en "U" invertida del primer perfil de sección general en "U" solidario a la cara posterior de la placa de encofrado, quedando el bulón con su orificio pasante respecto del plano de posicionamiento de la chaveta en el cuerpo corredera.At the anchor of the plates in orthogonal position each other the corresponding jester on the side of one of the plates formwork is passed through the corresponding hole in relation to the soul of the central projection in inverted "U" of the first profile of general section in "U" integral to the face back of the formwork plate, leaving the bolt with its through hole with respect to the positioning plane of the key in the sliding body.

Así, en la materialización del anclaje la chaveta es pasante por el orificio del bufón topando con su contorno de mayor radio sobre el alma del primer perfil a la vez que la pareja de tetones del cuerpo corredera topan sobre la superficie interna del contorno de menor radio de la chaveta.Thus, in the materialization of the anchor the key It is through the hole of the jester bumping its contour of greater radius on the soul of the first profile at the same time as the couple of lugs of the sliding body bump into the inner surface of the smaller radius contour of the key.

El cuerpo corredera definido por un segundo perfil de sección general en "U" de alma curva, en relación a la superficie curvo cóncava externa de su alma presenta un consistente saliente de golpeo para su deslizamiento por el primer perfil de sección general en "U" solidario a la cara externa de la respectiva placa de encofrado.The sliding body defined by a second "U" general section profile of a curved core, in relation to the external concave curved surface of his soul presents a consistent banging projection for its first slide general "U" section profile integral to the external face of the respective formwork plate.

Así, el cuerpo corredera, definido por un perfil de sección general en "U" de alma curva, portador de la correspondiente chaveta se monta en relación al primer perfil de sección general en "U" solidario a la cara externa de la placa de encofrado quedando con posibilidad de desplazamiento a lo largo de él para permitir el adecuado posicionamiento para el anclaje de las placas a unir e impidiéndose una posible perdida de la chaveta.Thus, the sliding body, defined by a profile of general section in "U" of curved soul, carrier of the corresponding key is mounted in relation to the first profile of general "U" section integral to the external face of the plate of formwork remaining with possibility of movement along from it to allow proper positioning for anchoring the plates to be joined and preventing a possible loss of the key.

Description of a preferred embodiment

A la vista de las comentadas figuras y de acuerdo con la numeración adoptada podemos observar como las placas 1 de encofrado se disponen en posición ortogonal en la configuración del encofrado de pilares y muros de pequeña envergadura, siendo las placas 1 de encofrado del tipo de las que presentan en uno de sus costados una serie de bulones dotados de un orificio pasante y en su cara posterior presentan unos perfiles transversales en relación a los cuales la placa 1 de encofrado dispone de un grupo de orificios alineados.In view of the commented figures and agree with the numbering adopted we can see how plates 1 of formwork are arranged orthogonally in the configuration of the formwork of small pillars and walls, being the formwork plates 1 of the type presented in one of their a series of bolts provided with a through hole and in their back face have transversal profiles in relation to which formwork plate 1 has a group of holes aligned.

Así, el sistema de anclaje que se presenta se constituye por estos primeros perfiles 2 transversales de sección general en "U" solidarios a la cara posterior de las placas 1 de encofrado, a los que se asocian respectivos cuerpos 10 corredera definidos por unos segundos perfiles de sección general en "U" portadores de correspondientes chavetas 11 de anclaje.Thus, the anchoring system presented is constitutes by these first profiles 2 cross section general "U" integral to the back of the plates 1 formwork, to which respective sliding bodies 10 are associated defined by a few seconds "U" general section profiles carriers of corresponding anchor keys 11.

De esta forma, los primeros perfiles 2 transversales presentan su alma 3 curvada dotada centralmente de un saliente 4 en "U" invertida cuya alma 5 queda enrasada con el extremo libre de las alas 6 del perfil 2, presentando las alas 6 del perfil 2 en "U", en relación al alma 3 curva, un saliente 7 hacia el exterior, quedando fijado el perfil 2 de sección general en "U" a la cara externa de la placa 1 de encofrado por el extremo libre de sus alas 6 y por el alma 5 de su saliente 4 central en "U" invertida.In this way, the first profiles 2 transversal features its curved soul 3 centrally endowed with a inverted 4-out "U" whose soul 5 is flush with the free end of wings 6 of profile 2, presenting wings 6 of the profile 2 in "U", in relation to the soul 3 curve, a projection 7 towards the outside, the profile 2 of the general section being fixed "U" to the outer face of the formwork plate 1 by the free end of its wings 6 and by the soul 5 of its central projection 4 in inverted "U".

En relación al alma 5 del saliente 4 central en "U" invertida de los primeros perfiles 2 presenta un grupo de orificios 8 alineados a través de los cuales es pasante el correspondiente bulón 9 de la placa 1 de encofrado adosada en ortogonal a ella en la materialización del anclaje por medio de una chaveta, a modo de cuña.In relation to the soul 5 of the central projection 4 in Inverted "U" of the first profiles 2 presents a group of holes 8 aligned through which the corresponding bolt 9 of the formwork plate 1 attached in orthogonal to it in the materialization of the anchor by means of a cotter, by way of wedge.

Los cuerpos 10 corredera que se asocian a los primeros perfiles 2 solidarios a la cara posterior de las placas 1 de encofrado se definen por un segundo perfil de sección general en "U" con su alma 12 curvada estando dotado de un corte 13 central en sus alas 14 prolongado hacia su alma 12 definiendo así las alas por una pareja de brazos dotados de una prolongación lateral provista de sendos salientes 15 presentando, respecto de una de sus alas, una prolongación 16 paralela y próxima al alma 12, estando dotadas en el espacio existente entre la prolongación 16 y el lateral del alma 12 de respectivos tetones 17 enfrentados.The sliding bodies 10 that are associated with the first profiles 2 integral to the rear face of the plates 1 formwork are defined by a second general section profile in "U" with its curved soul 12 being provided with a cut 13 central on its wings 14 prolonged towards its soul 12 thus defining the wings for a pair of arms endowed with an extension side provided with two projections 15 presenting, with respect to a of its wings, an extension 16 parallel and close to the soul 12, being provided in the space between extension 16 and the side of the soul 12 of respective lugs 17 facing each other.

Por otra parte, la chaveta 11 de anclaje que portan los cuerpos 10 corredera presentan una forma curva, a modo de cuña, y están dotadas de un regruesamiento 18 perimetral, excepto en un pequeño tramo 19 relativo a su contorno de menor radio y en proximidad a su extremo de mayor anchura.On the other hand, the anchor key 11 which they carry the sliding bodies 10 have a curved shape, by way of wedge, and are endowed with a perimeter thickness 18, except in a small section 19 relative to its minor contour radius and in proximity to its widest end.

Partiendo de estas estructuras en una primera fase se monta la correspondiente chaveta 11 en el cuerpo 10 corredera para lo cual el tramo 19 se encaja entre los tetones 17 enfrentados relativos a la prolongación 16 y al lateral del alma 3.Starting from these structures in a first phase the corresponding key 11 is mounted on the body 10 slide for which section 19 fits between the lugs 17 facing relative to prolongation 16 and lateral to the soul 3.

En una segunda fase el cuerpo 10 corredera, portando la correspondiente chaveta 11, se monta en relación a un primer perfil 2 solidario a la cara posterior de una placa 1 de encofrado encajando y enclavándose a presión los salientes 15 de sus alas 14 por los alientes 7 de sus alas 6, materializando un ajuste y presión adecuada para facilitar su deslizamiento pero sin posibilidad de liberación quedando así el cuerpo 10 corredera desplazable a lo largo del perfil 2.In a second phase the sliding body 10, bearing the corresponding key 11, it is mounted in relation to a first profile 2 integral to the rear face of a plate 1 of formwork fitting and locking the protrusions 15 of its wings 14 by the breath 7 of its wings 6, materializing a adequate adjustment and pressure to facilitate sliding but without possibility of release thus leaving the body 10 sliding movable along profile 2.

Así, una vez encajado y enclavado el cuerpo 10 corredera en el correspondiente perfil 2 la chaveta 11 no puede liberarse accidentalmente.Thus, once the body is fitted and locked 10 sliding in the corresponding profile 2 the key 11 cannot accidentally released.

Como puede observarse en los diseños las alas 14 del cuerpo 10 corredera presentan una menor longitud que las alas 6 del primer perfil 2, y, asimismo, el alma 3 curva del primer perfil 2 presenta un menor radio que el alma 12 del cuerpo 10 corredera.As you can see in the designs the wings 14 of the sliding body 10 have a shorter length than the wings 6 of the first profile 2, and also the soul 3 curve of the first profile 2 has a smaller radius than the soul 12 of the body 10 slide.

En la unión de dos placas 1 de encofrado en posición ortogonal entre sí la serie de bulones 9 de uno de los costados de una de las placas 1 de encofrado se encajan en respectivos orificios 8 de los distintos grupos alineados a diferentes alturas de la otra placa 1 de encofrado, de forma que para materializar el anclaje los cuerpo 10 corredera se desplazan a lo largo de los perfiles 1 para posicionar las chavetas 11 en relación a los orificios pasantes de los bulones 9.At the junction of two formwork plates 1 in orthogonal position with each other the series of bolts 9 of one of the sides of one of the formwork plates 1 fit into respective holes 8 of the different groups aligned to different heights of the other formwork plate 1, so that to materialize the anchor the sliding body 10 moves to along the profiles 1 to position the keys 11 in relation to the bolt through holes 9.

Para ello, el lateral del alma 12, relativo a la prolongación 16 presenta un entrante 20 curvo cóncavo que permite el posicionamiento del bulón 9 de unión con su orificio pasante en el mismo plano que la chaveta 11.For this, the side of the soul 12, relative to the extension 16 has a concave curved entrant 20 that allows the positioning of the connecting bolt 9 with its through hole in the same plane as the key 11.

De esta forma, se impide la perdida de las chavetas 11 y en el momento de efectuar el anclaje su contorno de mayor radio topa sobre el alma del perfil 1 y los tetones 17 topan sobre el contorno de menor radio, materializando un perfecto anclaje de las placas 1 de encofrado entre sí.In this way, the loss of keys 11 and at the time of anchoring its contour of larger radius bumps over the soul of profile 1 and the studs 17 bump on the outline of smaller radius, materializing a perfect anchoring the formwork plates 1 to each other.

El cuerpo 10 corredera puede estar dotado de un consistente saliente 21, en relación a la cara curvo cóncava externa para permitir su desplazamiento mediante golpeo en aquellos casos que sea necesario realizar una mayor fuerza y manualmente sea dificultoso.The sliding body 10 may be provided with a consistent protrusion 21, relative to the concave curved face external to allow its displacement by hitting in those cases that need to be stronger and manually be difficult.

El corte 13 de las alas 14 del cuerpo 10 corredera, así como el entrante curvo cóncavo del lateral opuesto a la prolongación 16 permite obtener un cuerpo más liviano sin perdida de rigidez.The cut 13 of the wings 14 of the body 10 sliding, as well as the concave curved entrant on the side opposite to the extension 16 allows to obtain a lighter body without loss of stiffness

Una importante ventaja del sistema descrito es que el hormigón no puede depositarse sobre las piezas conformantes del sistema.An important advantage of the described system is that concrete cannot be deposited on the forming parts of the system.

Lógicamente, en una variante de ejecución practica de la invención los cortes 13 de las alas del cuerpo corredera podrían obviarse.Logically, in an execution variant practice of the invention cuts 13 of the wings of the body Sliding could be ignored.
