Description

MÉTODO DE DIMENSIONAMIENTO DE ARMADURAS PARA VIGAS DE HORMIGÓN ARMADO.ARMOR DIMENSIONING METHOD FOR BEAMS OF REINFORCED CONCRETE.
Hasta ahora las armaduras para vigas de hormigón armado se definen por su anchura, su altura, su longitud, por el número y el diámetro de sus redondos superiores que generalmente tiene la longitud de la viga y por el número y diámetro de sus redondos longitudinales inferiores que pueden tener unos, la longitud de la viga y otros, los llamados redondos de refuerzo, que pueden tener una longitud menor; además una viga tiene estribos que se definen por su anchura y altura, el número de sus ramas verticales, el diámetro del redondo con el que están construidos y la separación a la que se colocan unos de otros.Until now, reinforcement for reinforced concrete beams is defined by its width, its height, its length, the number and diameter of its upper rounds that are generally the length of the beam and the number and diameter of its lower longitudinal rounds. which may have some, the length of the beam and others, the so-called round reinforcements, which may have a shorter length; in addition a beam has stirrups that are defined by its width and height, the number of its vertical branches, the diameter of the round with which they are constructed and the separation to which they are placed from each other.
Tanto el diámetro como el número de ramas verticales como la separación entre estribos pueden ser distintos a lo largo de la longitud de la viga, siendo generalmente el diámetro mas grande, el número de ramas verticales mayor y la separación mas pequeña cerca de las cabezas de la viga que en su parte central. Como ejemplo no limitativo una armadura convencional para viga de hormigón armado, puede tener varios redondos longitudinales superiores, varios redondos longitudinales inferiores de longitud igual a la de la armadura llamados redondos de refuerzo y los estribos, que pueden ser de varias ramas verticales, que tienen un ancho, una altura y están separados uno de otro una distancia variable. El diámetro de los redondos puede ser cualquiera de entre los fabricados de la gama usual de redondos para la construcción aunque lo habitual es que los redondos superiores varíe entre los diámetros 6 y 12 mm., el de los redondos inferiores entre los diámetros 8 y 25 mm., y el de los estribos entre los diámetros 6 y 12 mm. La armadura de las vigas se dimensiona para cumplirBoth the diameter and the number of vertical branches and the spacing between stirrups can be different along the length of the beam, generally being the largest diameter, the number of vertical branches greater and the smallest separation near the heads of the beam that in its central part. As a non-limiting example a conventional reinforcement for reinforced concrete beam, can have several upper longitudinal rounds, several lower longitudinal rounds of equal length to that of the armor called reinforcement rounds and stirrups, which can be of several vertical branches, which have a width, a height and they are separated from each other a variable distance. The diameter of the rounds can be any of those manufactured from the usual range of rounds for construction although it is usual for the upper rounds to vary between diameters 6 and 12 mm, that of the lower rounds between diameters 8 and 25 mm., and that of the stirrups between diameters 6 and 12 mm. The reinforcement of the beams is sized to meet
HOJADESUSTITUCIÓN(REGLA26) las condiciones que el cálculo impone y teniendo en cuenta además cómo se construyen los elementos que la componen. La forma de construir los estribos tanto en máquinas manuales como en estribadoras automáticas programables obliga a que las ramas horizontales superiores e inferiores de la armadura transversal tengan el mismo diámetro y estén separadas entre sí la misma distancia que las ramas verticales, cuando por necesidades del cálculo pueden tener un diámetro más pequeño y estar separadas una distancia sensiblemente superior a la de las ramas verticales. Así pues, hasta ahora lo conocido queda obsoleto, dada la novedad de este invento que se describen a continuación, sin que se encuentre nada parecido anteriormente y supone un gran ahorro de materiales y la posibilidad de la prefabricación de armaduras, con un gran ahorro de espacio. Por ello en nuestro método proponemos dimensionar de forma independiente las ramas verticales de la armadura transversal, de las ramas horizontales superiores e inferiores para conseguir un ahorro importante en los materiales empleados en la construcción de las armaduras .SUBSTITUTE SHEETS (RULE 26) the conditions that the calculation imposes and also taking into account how the elements that compose it are constructed. The way to build the stirrups both in manual machines and in programmable automatic stirrups forces the upper and lower horizontal branches of the transverse reinforcement to have the same diameter and be separated from each other the same distance as the vertical branches, when due to calculation needs they can have a smaller diameter and be separated a distance significantly greater than that of the vertical branches. Thus, until now, what is known is obsolete, given the novelty of this invention described below, without finding anything similar before and represents a great saving of materials and the possibility of prefabrication of reinforcements, with a great saving of space. Therefore, in our method we propose to independently dimension the vertical branches of the transverse reinforcement, of the upper and lower horizontal branches to achieve significant savings in the materials used in the construction of the reinforcements.
La idea de dimensionar de forma independiente las ramas verticales de la armadura transversal de las horizontales, nos conduce de forma natural a describir los principales componentes de la presente invención.The idea of independently sizing the vertical branches of the transverse reinforcement of the horizontal ones, naturally leads us to describe the main components of the present invention.
Los principales componentes de la armadura para vigas y pilares de hormigón armado basado en el método de dimensionamiento anterior son: Sub-armadura llamada reja y barras horizontales superior e inferior de la armadura transversal .The main components of the reinforcement for reinforced concrete beams and pillars based on the method of sizing above are: Sub-reinforcement called grating and upper and lower horizontal bars of the transverse reinforcement.
Diseñamos la armadura como un conjunto de sub- armaduras formadas cada una de ellas por un redondo superior y un redondo inferior, unidos mediante soldadura o cualquier otro método de fijación por varias ramasWe design the armor as a set of sub-armor each formed by an upper round and a lower round, joined by welding or any other method of fixing by several branches
HOJA DE SUSTITUCIÓN (REGLA 26) verticales; posteriormente estas sub-armaduras que llamamos rejas se unen entre sí por las ramas horizontales superior e inferior de la armadura transversal que serán generalmente de diámetro inferior a las ramas verticales de las rejas y estarán separadas una distancia mayor en el caso de armaduras para vigas de hormigón armado.SUBSTITUTE SHEET (RULE 26) vertical Subsequently, these sub-reinforcements that we call bars are joined together by the upper and lower horizontal branches of the transverse reinforcement that will generally be of smaller diameter than the vertical branches of the bars and will be separated a greater distance in the case of reinforcement for beams reinforced concrete.
Se completa la armadura, con los redondos inferiores, tanto de la misma longitud de la viga, como con los de menor longitud, los llamados redondos de refuerzo. Para la mejor comprensión de lo anteriormente expuesto, véanse la figuras 1 y 2.The reinforcement is completed, with the lower rounds, both of the same length of the beam, as with those of shorter length, the so-called reinforcement rounds. For the best understanding of the above, see Figures 1 and 2.
La armadura de la viga de hormigón se ha formado mediante las rejas 1-1' -IR, 2-2' -2R, 3-3' -3R, que tienen un redondo superior, un redondo inferior y varias ramas verticales unidas por las barras horizontales superior Hs e inferior Hi de la armadura transversal: además lleva dos redondos inferiores de longitud de las vigas números 4 y 5 y un redondo inferior de refuerzo 6 de longitud 1. Con esta forma de construir la armadura de la viga, hemos independizado las ramas verticales de la armadura transversal de sus ramas horizontales, pudiendo combinar el diámetro y separación de las ramas verticales de forma que el aprovechamiento de los materiales sea óptimo; además al ser independientes las armaduras horizontales Hs y Hi, de las ramas verticales pueden ser de diámetro inferior e ir mas separadas con el consiguiente ahorro de materiales.The reinforcement of the concrete beam has been formed using the 1-1 '-IR, 2-2' -2R, 3-3 '-3R bars, which have an upper round, a lower round and several vertical branches joined by the horizontal bars upper Hs and lower Hi of the transverse reinforcement: it also has two lower round lengths of beams numbers 4 and 5 and a lower round reinforcement 6 of length 1. With this way of constructing the beam reinforcement, we have become independent the vertical branches of the transverse reinforcement of its horizontal branches, being able to combine the diameter and separation of the vertical branches so that the use of the materials is optimal; in addition to being independent the horizontal reinforcements Hs and Hi, of the vertical branches can be of smaller diameter and go more separated with the consequent saving of materials.
Vemos pues que la armadura de las vigas de hormigón armado se ha formado con sub-armaduras (rejas) con redondos longitudinales tanto largos como de refuerzo y redondos transversales superior e inferior. En el sistema de construcción basado en el método de dimensionamiento, descrito anteriormente, se eliminan los estribos tradicionales y nace el concepto de sub-armadura (reja) .We see that the reinforcement of the reinforced concrete beams has been formed with sub-reinforcements (bars) with both long and reinforcement longitudinal rounds and upper and lower transverse rounds. In the construction system based on the sizing method, described above, the traditional stirrups are eliminated and the concept of sub-armor (grid) is born.
HOJA DE SUSTITUCIÓN (REGLA 26) Una sub-armadura (reja) es la unión de una barra longitudinal superior con una barra longitudinal inferior por medio de varias barras transversales verticales (ver Fig. 3 ó 4 a modo de ejemplo no limitativo) . Colocando a la separación adecuada el número de rejas que el cálculo nos pida para resistir el esfuerzo cortante llegamos a la anchura de la viga B. Vemos que una reja de altura H y longitud L puede ser empleada para formar vigas de cualquier anchura. Como además los diámetros de los redondos superiores e inferiores de la reja y de las barras transversales varían muy poco para vigas de longitud L, podemos tener prefabricadas las rejas ocupando muy poco espacio.SUBSTITUTE SHEET (RULE 26) A sub-reinforcement (grating) is the union of an upper longitudinal bar with a lower longitudinal bar by means of several vertical crossbars (see Fig. 3 or 4 by way of non-limiting example). Placing at the appropriate separation the number of bars that the calculation asks us to withstand the shear stress we reach the width of the beam B. We see that a fence of height H and length L can be used to form beams of any width. As the diameters of the upper and lower round of the fence and of the crossbars vary very little for beams of length L, we can have the bars prefabricated taking up very little space.
Otro elemento necesario para la construcción de las vigas son las barras transversales superiores e inferiores . Su longitud varia habitualmente de 5 en 5 centímetros, como la anchura de vigas y pilares y los diámetros usuales son el 6 y 8 mm. Por ello se pueden prefabricar en máquinas automáticas enderezadoras cortadoras de gran rendimiento y tenerlas almacenadas en un espacio muy pequeño. Lo que en esta invención se propone es el concepto de construir las armaduras para vigas y pilares de hormigón armado por medio de componentes prefabricados que se almacenan en un espacio pequeño y que permiten mediante su unión formar todo tipo de armaduras para vigas y pilares de hormigón armado de una forma rápida y económica. Estos componentes básicos son: la sub-armadura llamada reja y las barras horizontales superior e inferior de la armadura transversal. Añadiendo a estos componentes los redondos longitudinales libres tanto de la misma longitud de la viga como en los más cortos podemos construir cualquier armadura para vigas y pilares de hormigón armado, aprovechando el ahorro de materiales que el método de dimensionamiento nos permite y la versatilidad, rapidezAnother necessary element for the construction of the beams are the upper and lower crossbars. Its length usually varies from 5 to 5 centimeters, such as the width of beams and pillars and the usual diameters are 6 and 8 mm. For this reason, high performance cutting straightening machines can be prefabricated and stored in a very small space. What is proposed in this invention is the concept of building reinforcement for reinforced concrete beams and pillars by means of prefabricated components that are stored in a small space and that allow, by joining together, to form all types of reinforcement for concrete beams and pillars. assembled quickly and economically. These basic components are: the sub-reinforcement called grating and the upper and lower horizontal bars of the transverse reinforcement. Adding to these components the free longitudinal rounds of both the same length of the beam and in the shortest we can build any reinforcement for reinforced concrete beams and pillars, taking advantage of the material savings that the sizing method allows us and the versatility, speed
HOJA DE SUSTITUCIÓN (REGLA 26) y ahorro de espacio que la prefabricación nos posibilita. Una variante de la sub-armadura llamada reja, según figuras 7 y 8, consiste en que los redondos transversales en lugar de estar situados entre los redondos longitudinales, superior e inferior, están colocados sobre ellos y, unidos por soldadura o cualquier otro método de unión.SUBSTITUTE SHEET (RULE 26) and space saving that prefabrication allows us. A variant of the sub-armor called grating, according to figures 7 and 8, is that the transverse rounds instead of being located between the longitudinal, upper and lower rounds, are placed on them and, joined by welding or any other method of Union.
Con esta modificación facilitamos la construcción automatizada de la sub-armadura llamada reja. Otra mejora de esta variante consiste en la sustitución cuando por cálculo o fabricación sea conveniente de las armaduras transversales superior o inferior por la sub-armadura llamada reja definida en las figuras 7 y 8 de forma que podamos construir las armaduras para vigas y pilares de hormigón armado, tal como se indica en las figuras 5 y 6 por medio de una combinación de sub-armaduras (rejas) , 1-1' -IR, 2-2' -2R, 3-3' -3R, colocadas en posición vertical y otras sub- armaduras (rejas) , 4-4' -Hs - 5-5' -Hi, colocados en posición horizontal unidas entre sí por soldadura o cualquier otro método de unión. Se completa la armadura a modo de ejemplo no limitativo con los redondos libres inferiores largos 6 y 8 y el redondo libre corto 7 (ver figuras 5 y 6) . Otra variante de la sub-armaduras llamadas reja según figuras 9 y 10, se diferencian de las rejas descritas anteriormente en que los redondos transversales están unidos a los longitudinales por soldadura o cualquier otro método de unión y todos o parte de ellos están doblados sobre los longitudinales formando un gancho.With this modification we facilitate the automated construction of the sub-armor called gate. Another improvement of this variant consists in the substitution when by calculation or manufacture it is convenient for the upper or lower transverse reinforcements with the sub-reinforcement called a fence defined in Figures 7 and 8 so that we can build the reinforcement for concrete beams and pillars armed, as indicated in figures 5 and 6 by means of a combination of sub-reinforcements (grilles), 1-1 '-IR, 2-2' -2R, 3-3 '-3R, placed vertically and other sub-reinforcements (bars), 4-4 '-Hs - 5-5' -Hi, placed horizontally joined together by welding or any other joining method. The reinforcement is completed by way of non-limiting example with the long bottom free rounds 6 and 8 and the short free round 7 (see figures 5 and 6). Another variant of the sub-reinforcements called grating according to figures 9 and 10, differ from the gratings described above in that the transverse rounds are joined to the longitudinals by welding or any other joining method and all or part of them are bent over the Longitudinal forming a hook.

A modo de ejemplo no limitativo dibujamos una armadura para vigas de hormigón armado (fig. 13 y 14) en la que combinamos las sub-armaduras descritas según figuras 9 y 10, colocadas en posición vertical 1-1' -IR, 2-2' -2R, 3-3' -3R, con la sub-armadura descrita según figuras 7 y 8, colocadas en posición horizontal inferior 4-4' -Hi y con barras horizontales sueltas colocadas en posición horizontal superior Hs .As a non-limiting example we draw a reinforcement for reinforced concrete beams (figs. 13 and 14) in which we combine the sub-reinforcements described according to figures 9 and 10, placed in a vertical position 1-1 '-IR, 2-2 '-2R, 3-3' -3R, with the sub-armor described according to figures 7 and 8, placed in a lower horizontal position 4-4 '-Hi and with loose horizontal bars placed in a superior horizontal position Hs.
