Abstract

The invention relates to a system comprising at least three shaped, interlaced structural elements forming one or more triangles which can absorb forces and movements along the three axes: x, y, z. In this way, the weight of the system is reduced and the three-dimensional structural resistance thereof is improved in relation to other standardised structural systems. The inventive system can be combined with other innovative structural systems or used to reinforce existing systems in order to improve the qualities thereof.

Sistema estructural tridimensional.Three-dimensional structural system.
El invento consiste en un sistema compuesto de tres o más elementos estructurales conformados, entrelazados entre sí , formando una o varias triangulaciones las cuales nos permiten absorciones de fuerzas y movimientos en los tres ejes; x,y,z.The invention consists of a system composed of three or more structural elements formed, interwoven with each other, forming one or several triangulations which allow us to absorb forces and movements in the three axes; X and Z.
De esta manera se obtiene la reducción de peso y el aumento de resistencia estructural tridimensional a diferencia de otro u otros sistemas estructurales normalizados.In this way the reduction of weight and the increase of three-dimensional structural resistance is obtained unlike other or other standardized structural systems.
El sistema se puede combinar con otros sistemas estructurales bien sean de nueva realización o reforzar sistemas ya realizados para aumentar las cualidades de los mismos.The system can be combined with other structural systems, whether they are new or reinforce existing systems to increase their qualities.
2.-SECTOR.-2.-SECTOR.-
Construcciones arquitectónicas. Construcciones navales ,aeroespaciales y cualquier sector donde se pudiera aplicar el sistema.Architectural constructions Naval, aerospace and any sector where the system could be applied.
3.-ESTADO DE LA TECNICA.-3.-STATE OF THE TECHNIQUE.-
Los sistemas estructurales actuales se basan en un conjunto de elementos rígidos (elementos conformados ,laminados, troquelados ) los cuales son unidos entre si bien sean atornillados, soldados , o encastrados . Todos estos elementos que suelen ser rígidos en su constitución tienen determinados todos los esfuerzos en ejes lineales como x-x ,y-y; esto implica que deben estar sobredimensionados para los esfuerzos a resistir puesto que las absorciones de los mismos no son tridimensionales sino que son linealmente o superficiales, no pudiendo absorber los momentos de inercia máximos que se puedan producir en un determinado momento produciéndose una deformación estructural e incluso una rotura de los mismos.The current structural systems are based on a set of rigid elements (shaped, laminated, stamped elements) which are joined together even if they are screwed, welded, or embedded. All these elements that are usually rigid in their constitution have all the efforts on linear axes such as xx, yy; this implies that they must be oversized for the efforts to resist since the absorptions thereof are not three-dimensional but are linearly or superficially, not being able to absorb the maximum moments of inertia that may occur at a given time, producing a structural deformation and even a breakage thereof.
Por ello cuando se calculan dichos elementos se incrementan sus medidas de sección incrementándose proporcionalmente el peso del elemento y en consecuencia todo el conjunto estructural .Therefore, when these elements are calculated, their section measurements are increased by proportionally increasing the weight of the element and, consequently, the entire structural assembly.
4.-EXPLICACION DE LA INVENCIÓN.4.-EXPLANATION OF THE INVENTION.
Se trata de la unión de tres o más elementos en forma de semicírculos continuos y contrapuestos linealmente donde se unen asimétricamente en módulos alternos formando varias triangulaciones entre si generando barras y nudos estructurales totalmente dinámicos. Con ello obtenemos una regidedez estructural superior a otro elemento tipo que fuere el apropiado para la misma función, pero el peso se reduce en consideración y la resistencia del elemento es la misma en los tres ejes ;x,y,z.It is the union of three or more elements in the form of continuous and linearly opposed semicircles where they are joined asymmetrically in alternate modules forming several triangulations of each other generating totally dynamic structural rods and bars. With this we obtain a structural rigidity superior to another type element that is appropriate for the same function, but the weight is reduced in consideration and the resistance of the element is the same in the three axes; x, y, z.
Respecto a la absorción de movimiento con el sistema estructural tridimensional se incrementa la estabilidad y la máxima absorción del mismo, puesto que la forma geométrica de los semicírculos conlleva una pretensión estructural añadida en diferencia a cualquier tipo de elemento lineal rígido, la cual al trabajar multidireccionalmente siempre compensa dichos movimientos y esfuerzos.Regarding the absorption of movement with the three-dimensional structural system, its stability and maximum absorption are increased, since the geometric shape of the semicircles entails a structural claim added unlike any type of rigid linear element, which when working multidirectionally always compensates for such movements and efforts.
Esta teoría esta contemplada en el método analítico fundamentado en las condiciones generales de equilibrio; es decir, si en un sistema reticulado todos los esfuerzos están en equilibriosa suma de los momentos, con respecto a un punto cualquiera del reticulado es igual a 0.This theory is contemplated in the analytical method based on the general equilibrium conditions; that is, if in a reticulated system all the efforts are in equilibrium sum of the moments, with respect to any point of the reticulate it is equal to 0.
El sistema de unión de los puntos convergentes se puede realizar mediante sistema de soldadura ( mig, tig, arco sumergido.electrodo ) , bien atornillada mediante elementos auxiliares de suportación , bien comprimida por cualquier sistema de compresión y elementos cualificados para proceder a la misma o cualquier otro método de unión que ofrezca unas garantías comprobadas de resistencia en consideración a los cálculos de resistencia .dilatación, torsión , esbeltez y abonamiento del sistema estructural siempre en consideración al tipo de material que se utilice .The joining system of the converging points can be done by welding system (mig, tig, submerged arc and electrode), well screwed by auxiliary support elements, well compressed by any compression system and qualified elements to proceed to it or any other joining method that offers proven guarantees of resistance in consideration of the calculations of resistance. dilation, torsion, slenderness and fertilization of the structural system always in consideration of the type of material used.
Referente a otros sistemas estructurales, el sistema estructural tridimensional puede formar parte de los mismos, bien sea total o parcial mente. Según los sistemas estructurales definidos como: articulados ( sistema isostatico, sistema hiperestatico , sistema hipoestatico) , los no articulas , los reticulados y los espaciales , todos ellos utilizan barras fijas sin triangular con perfilaría estándar según norma, sustituyendo estos elementos por barras con sistema estructural tridimensional se obtendría mayor resistencia dinámica y estática, menores cargas puntuales pudiendo ampliar las luces estructurales entre apoyos, obteniendo elementos estructurales de alta resistencia y bajo peso así como mínimas deformaciones en situaciones extremas.Regarding other structural systems, the three-dimensional structural system can be part of them, either totally or partially. According to the structural systems defined as: articulated (isostatic system, hyperstatic system, hypostatic system), non-articulated, cross-linked and spatial systems, all of them use fixed triangular bars with standard profiles according to norm, replacing these elements with bars with structural system three-dimensional, greater dynamic and static resistance would be obtained, lower punctual loads being able to expand the structural lights between supports, obtaining structural elements of high resistance and low weight as well as minimal deformations in extreme situations.
