Abstract

Fibra con geometría optimizada para el refuerzo del hormigón y el mortero que muestra una sección circular con cuatro resaltes triangulares equidistantes, mejorando la adherencia de la fibra al material donde se encuentra embebida.Fiber with optimized geometry for the reinforcement of concrete and mortar that shows a circular section with four equidistant triangular projections, improving the adhesion of the fiber to the material where it is embedded.

Description

Fibra con geometría optimizada para el refuerzo del hormigón y el mortero.Fiber with optimized geometry for reinforcement of concrete and mortar.

Objeto de la invenciónObject of the invention

La presente invención se refiere a una fibra con geometría optimizada para el refuerzo del hormigón y mortero.The present invention relates to a fiber with  Optimized geometry for concrete and mortar reinforcement.

La especial geometría de la fibra de esta invención que muestra una sección circular con cuatro resaltes triangulares equidistantes, mejora la adherencia de la fibra al material donde se encuentra embebida.The special fiber geometry of this invention showing a circular section with four projections triangular equidistant, improves fiber adhesion to material where it is embedded.

Antecedentes de la invenciónBackground of the invention

Es conocida la utilización de fibras para mejorar las propiedades mecánicas del hormigón como la resistencia y la tracción.The use of fibers for improve the mechanical properties of concrete such as strength and traction

Generalmente el hormigón presenta unas fuerzas de comprensión muchas más altas que sus fuerzas de tensión. Por esto el hormigón tiende a romperse bajo estas fuerzas de tensión.Generally the concrete has forces of understanding much higher than their tensile forces. By this concrete tends to break under these forces of tension.

Las fibras que se embeben en el hormigón evitan las microfisuras que se puedan dar en éste, las fibras proporcionan al hormigón en fresco, una mayor resistencia a la migración del agua, pudiéndose trabajar mejor en él, durante más tiempo, y finalmente proporcionan al hormigón una mayor resistencia al impacto.The fibers that are embedded in the concrete avoid the microcracks that can occur in it, the fibers provide to fresh concrete, greater resistance to the migration of water, being able to work better on it, for longer, and finally they provide concrete with greater resistance to impact.

En la patente con nº de publicación ES2060135 se describen fibras que constituidas por poliolefina mejoran las características de un material constituido a base de cemento.In the patent with publication number ES2060135  describe fibers that constituted by polyolefin improve the characteristics of a cement-based material.

Descripción de la invenciónDescription of the invention

La presente invención consiste en una fibra con una geometría optimizada para el refuerzo del hormigón.The present invention consists of a fiber with a geometry optimized for concrete reinforcement.

La especial geometría de la fibra que muestra en sección cuatro resaltes triangulares equidistantes entorno a un círculo, aumenta la superficie de anclaje entre la fibra y la materia que la contiene, respecto a una fibra circular y de esta manera mejora la adherencia de la misma al hormigón, incrementando la resistencia a la tracción del mismo. De la misma manera se disminuye las microfisuras del material que las contiene.The special geometry of the fiber shown in  section four equidistant triangular highlights around a circle, increases the anchoring surface between the fiber and the matter that contains it, with respect to a circular fiber and of this way improves the adhesion of the same to the concrete, increasing the tensile strength thereof. In the same way it decreases the microcracks of the material that contains them.

Las fibras de la presenten invención son preferentemente de polipropileno, este material hace que las mismas sean ligeras, fuertes, resistentes a productos químicos, que no se oxiden y que no absorban el agua.The fibers of the present invention are preferably of polypropylene, this material makes the they are light, strong, resistant to chemicals, which They do not oxidize and do not absorb water.

De la misma manera que en el refuerzo de hormigón las fibras de la presente invención pueden ser utilizadas para el refuerzo de morteros.In the same way as in the reinforcement of concrete fibers of the present invention can be used for mortar reinforcement.

Descripción de los dibujosDescription of the drawings

Se complementa la presente memoria descriptiva, con un juego de planos, ilustrativos del ejemplo preferente y nunca limitativos de la invención.This descriptive report is complemented, with a set of drawings, illustrative of the preferred example and never Limitations of the invention.

La Figura 1 muestra una vista en perspectiva de la fibra de la invención.Figure 1 shows a perspective view of The fiber of the invention.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de lo anteriormente enunciado, la presente invención consiste en una fibra (1) con geometría optimizada para el refuerzo del hormigón.In view of the foregoing, the The present invention consists of a fiber (1) with geometry optimized for concrete reinforcement.

Las fibras (1) de la presente invención se añaden en el hormigón o en mortero en forma de haces, consiguiendo una distribución homogénea por todo la masa de hormigón, de esta manera se evitan la formación de microfisuras en la masa de hormigón aumentando su resistencia.The fibers (1) of the present invention are add in concrete or mortar in the form of beams, getting a homogeneous distribution throughout the concrete mass, of this way the formation of microcracks in the mass of concrete increasing its resistance.

Los haces de fibras tienen de 10 a 10.000 filamentos y una longitud de 1 a 50 mm.The fiber bundles have 10 to 10,000 filaments and a length of 1 to 50 mm.

No alteran la esencialidad de esta invención variaciones en materiales, forma, tamaño y disposición de los elementos componentes, descritos de manera no limitativa, bastando ésta para proceder a su reproducción por un experto.They do not alter the essentiality of this invention variations in materials, shape, size and arrangement of component elements, described in a non-limiting manner, sufficient this one to proceed to its reproduction by an expert.
