Description
Dispositivo para la anulación de tensiones estructurales internas en fundiciones.Device for stress cancellation internal structural foundries.
La presente invención se refiere a un dispositivo para la anulación de las tensiones estructurales internas que aparecen en las obras de hormigón, durante y especialmente después del fraguado del mismo, en todo tipo de construcciones con este material.The present invention relates to a device for cancellation of structural stresses internal that appear in concrete works, during and especially after setting it, in all kinds of constructions with this material.
El dispositivo consiste en un tubo de material plástico ligero, tipo porexpan, que colocado en su posición correcta dentro del hormigón, durante la construcción, resiste indemne todo el proceso del fraguado y es fácilmente eliminable mediante proceso químico o mecánico, una vez que el hormigón alcanza su resistencia característica.The device consists of a material tube lightweight plastic, porexpan type, which placed in position correct inside the concrete, during construction, it resists undamaged the entire setting process and is easily removable by chemical or mechanical process, once the concrete It reaches its characteristic resistance.
De esta forma se deja un hueco-orificio en el interior de la construcción, con lo que se permite el paso del aire a la temperatura adecuada, dándose un correcto secado desde dentro a fuera, así como desde fuera hacia dentro, de las piezas construidas. Con ello se consigue una construcción plenamente satisfactoria y sin las peligrosas tensiones internas que puedan producir grietas y roturas.This leaves a hole-hole inside the construction, which allows the passage of air at the right temperature, giving a correct drying from inside to outside, as well as from outside in, of the built pieces. This is achieved a fully satisfactory construction without the dangerous internal tensions that can cause cracks and breaks.
Un problema que se presenta siempre en las obras de hormigón es la aparición de tensiones internas, con sus consiguientes grietas interiores, debidas al proceso de fraguado de la masa, ya que, como es bien sabido, este fraguado es exotérmico.A problem that always appears in the works Concrete is the appearance of internal tensions, with their consequent internal cracks, due to the setting process of the dough, since, as is well known, this setting is exothermic.
Una solución evidente para obtener un orificio o cualquier otro tipo de apertura-hueco en una obra de hormigón, consiste en un dispositivo que, introducido dentro de la masa sin fraguar, pueda resistir todas las condiciones que se produzcan durante el fraguado (presiones, calor, etc.), y que luego pueda ser anulado mediante un proceso químico o mecánico, dejando dentro del hormigón el hueco por él ocupado antes de su desaparición.An obvious solution to get a hole or any other type of opening-hole in a work concrete, consists of a device that, introduced into the dough without setting, can withstand all the conditions that are produced during setting (pressures, heat, etc.), and then can be canceled by a chemical or mechanical process, leaving inside the concrete the hole he occupied before his disappearance.
Al quedar el hueco dejado por el dispositivo dentro del hormigón, este permite el paso de aire a su través, facilitando un secado gradual, tanto desde dentro de la masa hacia fuera, como en sentido contrario, lo cuál facilita la no aparición de tensiones internas, ni de las grietas producidas por ellas.With the gap left by the device inside the concrete, this allows the passage of air through it, facilitating a gradual drying, both from inside the dough towards outside, as in the opposite direction, which facilitates the non-appearance of internal tensions, nor of the cracks produced by them.
El dispositivo para la anulación de tensiones estructurales internas en obras de hormigón que la invención propone, resuelve el problema y el peligro de la aparición de grietas y roturas en las construcciones de este material.The device for stress cancellation structural structures in concrete works that the invention proposes, solves the problem and the danger of the appearance of cracks and breaks in the constructions of this material.
Mediante una correcta y adecuada implantación del dispositivo, que está construido a partir de un cuerpo monopieza (o también de varias piezas), se dota a las obras construidas con hormigón, de un orificio interno que las aligera de material. La posición exacta y adecuada dentro de la masa de hormigón puede garantizarse mediante puntos de fijación axial.Through proper and proper implementation of the device, which is built from a body monopieza (or also of several pieces), the works are endowed constructed with concrete, of an internal hole that lightens them of material. The exact and appropriate position within the mass of Concrete can be guaranteed by axial fixing points.
Después de verter la masa de hormigón, el dispositivo fabricado con material plástico ligero, tipo porexpan, resiste indemne el proceso de fraguado del hormigón, siguiendo en su posición inicial cuando se alcanza la resistencia característica del mismo.After pouring the concrete mass, the device made of lightweight plastic material, type porexpan, resists the concrete setting process unscathed, following in its initial position when the characteristic resistance is reached of the same.
Una vez terminado el fraguado del hormigón, el dispositivo muestra la particularidad de que puede ser eliminado fácilmente mediante un proceso mecánico o químico, obteniéndose así una estructura capaz de dejar pasar el aire a través de ella, a la temperatura adecuada, lográndose de esta manera el correcto secado de la pieza construida desde su interior al exterior, y viceversa, evitándose así la aparición de tensiones internas con sus correspondientes grietas.Once the concrete setting is finished, the device shows the peculiarity that it can be removed easily by a mechanical or chemical process, thus obtaining a structure capable of letting air pass through it, to the adequate temperature, thus achieving the correct drying of the piece built from inside to outside, and vice versa, thus avoiding the appearance of internal tensions with their corresponding cracks.
El dispositivo, por su estructura funcional, permite su implantación en obras horizontales, verticales y curvadas.The device, due to its functional structure, allows its implementation in horizontal, vertical and curved
