ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Es conocido que la inclusión de un marcaje lateral de las placas de hormigón aporta ventajas a su comportamiento en obra. Así, las placas con dicho marcaje 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 marcaje 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 side 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 marking of the plates allows reducing 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.
