The invention, as stated in the present specification, refers to a machine for the continuous manufacture of prestressed concrete plates, which has novelty characteristics that will be described in detail below.
El objeto de la presente invención recae en una máquina de fabricación en continuo de placas pretensadas de hormigón que se distingue por comprender unos medios para aplicar un mareaje en forma de dentado lateral a las placas, destinado a mejorar su comportamiento en obra, para lo cual, dicha máquina está dotada de un mecanismo que, controlado manualmente realiza dicho mareaje automáticamente. The object of the present invention lies in a machine for the continuous manufacture of prestressed concrete plates that is distinguished by comprising means for applying a lateral serration shape to the plates, intended to improve their performance on site, for which , said machine is provided with a mechanism that, manually controlled, performs said tide automatically.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la construcción, centrándose particularmente en el ámbito de la industria dedicada a la fabricación de maquinaria para la fabricación de elementos constructivos, en particular placas pretensadas de hormigón. The scope of the present invention is framed within the construction sector, focusing particularly on the field of industry dedicated to the manufacture of machinery for the construction of construction elements, in particular prestressed concrete slabs.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Es conocido que la inclusión de un mareaje lateral de las placas de hormigón aporta ventajas a su comportamiento en obra. Así, las placas con dicho mareaje en los laterales adyacentes a una placa contigua quedan más ligadas entre sí en las zonas sísmicas, por lo que se conocen como placas anti-sísmicas. Pero, además, para un valor de fricción dado entre ellas, el mareaje lateral de las placas permite disminuir la cantidad de hormigón que se vierte para completar el piso o estructura de hormigón, lo cual supone, por tanto, un ahorro de material y de costes. It is known that the inclusion of a lateral marking of concrete slabs brings advantages to their behavior on site. Thus, the plates with said marking on the sides adjacent to a contiguous plate are more closely linked to each other in the seismic zones, so they are known as anti-seismic plates. But, in addition, for a given friction value between them, the lateral mareaje of the plates allows to reduce the amount of concrete that is poured to complete the concrete floor or structure, which, therefore, saves material and material costs
En cualquier caso, no se conoce la existencia de ninguna máquina o invención similar que permita efectuar de manera práctica dicho mareaje a las placas en el mismo momento de su fabricación, siendo este el objetivo de la presente invención. In any case, the existence of any machine or invention is unknown. similar that allows to carry out in a practical way said marking to the plates at the same time of its manufacture, this being the objective of the present invention.
Así, pues, como referencia al estado actual de la técnica, al menos por parte del solicitante, se desconoce la existencia de ninguna otra máquina o invención que presente unas características técnicas, estructurales y constitutivas semejantes a las que presenta la que aquí se reivindica. Thus, as a reference to the current state of the art, at least on the part of the applicant, the existence of any other machine or invention that has similar technical, structural and constitutive characteristics to those presented here is claimed.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
La máquina de fabricación en continuo de placas pretensadas de hormigón que la invención propone se configura, pues, como una novedad dentro de su campo de aplicación, ya que a tenor de su implementación se alcanzan satisfactoriamente los objetivos señalados, estando los detalles caracterizadores que lo hacen posible y que la distinguen convenientemente recogidos en las reivindicaciones finales que acompañan la presente descripción. The machine for the continuous manufacture of prestressed concrete plates that the invention proposes is thus configured as a novelty within its field of application, since according to its implementation the stated objectives are satisfactorily achieved, the characterizing details being make it possible and conveniently distinguishable in the final claims that accompany the present description.
Concretamente, lo que la invención propone, como se ha señalado anteriormente, es una máquina de fabricación en continuo de placas pretensadas de hormigón, utilizando una máquina de fabricación por extrusión mediante la gravedad de una columna de hormigón, aunque sin que ello suponga una limitación, la cual se distingue por comprender medios para aplicar un mareaje en forma de dentado en ambos laterales a las placas durante el proceso de formación de las mismas, el cual, con un espesor de, al menos, 5 milímetros, está eminentemente destinado a mejorar su comportamiento en obra, por ejemplo ante movimientos sísmicos para minimizar los movimientos relativos entre placas contiguas. Specifically, what the invention proposes, as noted above, is a continuous manufacturing machine for prestressed concrete plates, using an extrusion manufacturing machine by means of the gravity of a concrete column, although without limiting it. , which is distinguished by comprising means for applying a serrated-shaped marking on both sides to the plates during the process of forming them, which, with a thickness of at least 5 millimeters, is eminently intended to improve its behavior on site, for example before seismic movements to minimize relative movements between adjacent plates.
Para ello, y de modo más específico, la máquina de la invención, además de los elementos conocidos para conformar la placas, tales como una estructura portante, un alimentador de hormigón y unas guías laterales a la zona de expulsión que determinan su dimensión y forma, pudiendo incluir elementos para dotarla de huecos alveolares, está dotada de un mecanismo que imprime dicho dentado a los laterales de la placa en el momento de su conformación. Dicho mecanismo, preferentemente de accionamiento hidráulico, comprende, preferentemente, una pieza de molde de mareaje, con la configuración escogida, asociada a la estructura del mismo en una zona apropiada de la zona de expulsión, de tal modo que, cuando convenga, se desplaza para presionar y marcar el relieve dentado correspondiente sobre la superficie lateral de hormigón aún fresco. Para ello, el accionamiento de este mecanismo sincronizado con el avance automático de la máquina, se realiza mediante un selector en el cuadro de mandos. Si el selector se encuentra en la posición de reposo, el mecanismo no actúa. For this, and more specifically, the machine of the invention, in addition to the known elements for forming the plates, such as a supporting structure, a concrete feeder and lateral guides to the ejection zone that determine its dimension and shape , and may include elements to provide it with hollow holes, it is equipped with a mechanism that prints said teeth to the sides of the plate at the time of its formation. Said mechanism, preferably of hydraulic actuation, preferably comprises a part of a mold of mareaje, with the chosen configuration, associated with its structure in an appropriate area of the ejection zone, so that, when appropriate, it moves to press and mark the corresponding indented relief on the side surface of concrete still fresh. For this, the operation of this mechanism synchronized with the automatic advance of the machine, is carried out by means of a selector in the control panel. If the selector is in the idle position, the mechanism does not work.
En caso de estar previsto el mecanismo de control automático, dicho mecanismo se conecta a un autómata programable para calcular en qué momento debe accionar el repetido mecanismo. If the automatic control mechanism is provided, said mechanism is connected to a programmable automaton to calculate when the repeated mechanism should be activated.
