ESTRUCURA PLÁSTICA CON ARMAZÓN INTERIORPLASTIC STRUCTURE WITH INTERIOR FRAME
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
Es objeto de la presente invención, tal y como el título de la invención establece una estructura plástica con armazón interior donde el armazón interior es una armadura metálica preferentemente realizada en malla electrosoldada.It is the object of the present invention, as the title of the invention establishes a plastic structure with an internal frame where the internal frame is a metallic frame, preferably made of electro-welded mesh.
Caracteriza a la presente invención el hecho de disponer dentro de una estructura plástica un armazón interior de malla, consiguiendo una resistencia estructural no conseguida hasta el momento.The present invention is characterized by the fact of arranging an internal mesh frame within a plastic structure, achieving a structural resistance not achieved up to now.
Por lo tanto, la presente invención se circunscribe dentro del ámbito de los elementos plásticos fabricados, tales como contenedores, o elementos de uso cotidiano sometidos a requerimientos de carga estructural importantes.Therefore, the present invention is circumscribed within the field of manufactured plastic elements, such as containers, or elements of daily use subjected to significant structural load requirements.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Actualmente todos los esfuerzos realizados para poder dotar a elementos plásticos de una mayor resistencia estructural están orientados hacia la elaboración de resinas y polímeros más resistentes, también en el diseño de las propias piezas mediante la inclusión de refuerzos o nervios del mismo material constitutivo de la pieza a modo de cartelas o refuerzos estructurales. Estos diseños reforzados dificultan la consecución de superficies lisas y fáciles de limpiar.Currently, all the efforts made to provide plastic elements with greater structural resistance are oriented towards the production of more resistant resins and polymers, also in the design of the pieces themselves by including reinforcements or ribs of the same material that makes up the piece. as gussets or structural reinforcements. These reinforced designs make it difficult to achieve smooth, easy-to-clean surfaces.
Los elementos actuales elaborados en material plástico tienen el límite de resistencia que les da la resistencia del material del cual están constituidos, siendo el punto del material que recibe el impactó o el esfuerzo el que ha de realizar todo el trabajo.The current elements made of plastic material have the resistance limit that gives them the resistance of the material from which they are made, being the point of the material that receives the impact or the effort that has to carry out all the work.
Hay polímeros de alta resistencia a los impactos, pero su alto coste los hace prohibitivos para la elaboración de elementos de gran tamaño como contenedores de basura o muebles de jardín entre otros, o aquellos cuyo precio tenga que ser reducido. There are polymers with high resistance to impacts, but their high cost makes them prohibitively expensive for the production of large elements such as garbage containers or garden furniture, among others, or those whose price has to be reduced.
Por lo tanto, es objeto de la presente invención desarrollar unos medios que superen los inconvenientes del estado de la técnica relativos a la falta de resistencia estructural de objetos plásticos sometidos a esfuerzos y requerimientos de carga sin incurrir en altos costes o realizar complejos diseños que requieren la presencia de cartelas, nerviaciones o regruesamientos, desarrollando una estructura plástica como la que a continuación se describe y queda recogida en su esencialidad en la reivindicación primera.Therefore, it is the object of the present invention to develop means that overcome the drawbacks of the state of the art related to the lack of structural resistance of plastic objects subjected to stress and load requirements without incurring high costs or carrying out complex designs that require the presence of gussets, ribs or thickening, developing a plastic structure as described below and is contained in its essentials in the first claim.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
Es objeto de la presente invención queda recogido en su esencialidad en la reivindicación independiente y las diferentes realizaciones están recogidas en las reivindicaciones dependientes.The object of the present invention is collected in its essentials in the independent claim and the different embodiments are included in the dependent claims.
La presente invención tiene por objeto una estructura plástica con armazón interior, donde dicho armazón interior es una malla metálica, preferentemente electrosoldada, pudiendo quedar unidos los diferentes tramos entre ellos por cualquiera de los métodos conocidos.The object of the present invention is a plastic structure with an internal frame, where said internal frame is a metal mesh, preferably electro-welded, the different sections being able to be joined together by any of the known methods.
Todo el armazón interior queda embebido dentro de un material plástico o polimérico.The entire interior frame is embedded within a plastic or polymeric material.
Dicho armazón interior se configura en primer lugar disponiéndose en aquellos lugares del objeto final donde se considere deba contar con un mayor refuerzo estructural, pudiendo incluso dejar partes del objeto sin armazón alguno, para a continuación, colocar dicho armazón en el interior del molde procediendo finalmente a verter el plástico o polímero líquido cubriendo toda la estructura del armazón.Said interior framework is configured in the first place by placing it in those places of the final object where it is considered to have greater structural reinforcement, being able to even leave parts of the object without any framework, to then place said framework inside the mold, finally proceeding to pour the plastic or liquid polymer covering the entire structure of the frame.
Conceptualmente es muy similar a lo que se hace con las estructuras de hormigón armado en las que en primer lugar se coloca una malla de acero corrugado o malla metálica, donde la unión entre los cruces de las armaduras bien se realiza mediante electrosoldado o mediante unión, para finalmente verte el hormigón líquido.Conceptually it is very similar to what is done with reinforced concrete structures in which a corrugated steel mesh or metal mesh is first placed, where the union between the crosses of the reinforcements is either carried out by electro-welding or by union, to finally see you the liquid concrete.
El armazón interior en una posible forma de realización preferente pero nunca limitativa, puede ser integral, ya que de lo contrario los esfuerzos se transmitirán a las partes no incluidas provocando roturas, las cadenas siempre se rompen por el eslabón mas débil, pero cabe la posibilidad de que el esqueleto o armazón interior sea parcial, no en la totalidad interior del objeto donde se quiere ubicar si no solamente en ciertas partes. The inner frame in a possible preferred but never limiting embodiment, can be integral, since otherwise the efforts will be transmitted to the parts not included causing breakage, the chains always break at the weakest link, but it is possible that the skeleton or interior framework is partial, not in the entire interior of the object where it is to be located, but only in certain parts.
En la malla metálica se pueden fijar por soldadura u otro método tuercas, tomillos, bisagras u otros elementos para unir varias piezas cuando sea necesario (por ejemplo las patas de una mesa de jardín) y evitar que esa unión sea un punto débil, y también la colocación en la malla de pastillas separadoras del mismo plástico constitutivo de la pieza como elemento que asegure que la malla quede correctamente colocada en el molde a fin de asegurar que la distancia a la superficie de la pieza sea la correcta y no asome al exterior, con los problemas estéticos y de corrosión que generaría.Nuts, screws, hinges or other elements can be fixed to the metal mesh by welding or another method to join several pieces when necessary (for example, the legs of a garden table) and prevent that union from being a weak point, and also the placement in the mesh of separator tablets of the same plastic that constitutes the piece as an element that ensures that the mesh is correctly placed in the mold in order to ensure that the distance to the surface of the piece is correct and does not show to the outside, with the aesthetic and corrosion problems that it would generate.
Son cosas que quizás por obvias no se puedan patentar ¿O si? Pero en todo caso quizás será adecuado incluir para que quede mas claro el proceso constructivo y evitar que algún otro las patente para mejorar nuestro proceso.These are things that perhaps because they are obvious they cannot be patented, right? But in any case, perhaps it will be appropriate to include them so that the construction process is clearer and to prevent someone else from patenting them to improve our process.
Gracias al hecho de disponer un armazón metálico embebido en la estructura plástica se consigue dotar de una resistencia estructural incrementada, aunando por un lado los beneficios de un armazón metálico y por otro lado los del plástico que permite obtener superficies lisas, y durante el proceso de moldeo cubrir todo el armazón sin dejar nada de él visto.Thanks to the fact of having a metal frame embedded in the plastic structure, it is possible to provide increased structural resistance, combining on the one hand the benefits of a metal frame and on the other hand those of plastic that allows smooth surfaces to be obtained, and during the process of molding cover the entire frame without leaving anything of it visible.
