Description
Cuerpo de relleno aligerador para losas y forjados de hormigón Lightweight filler body for concrete slabs and floors
La presente invención tiene por objeto un cuerpo de relleno que se utiliza para ocupar el espacio no sujeto a tensiones en una losa de hormigón armado con parrillas o varillas metálicas (por ejemplo para un forjado), que está provisto de un conjunto de nervaduras separadoras, sobre las que apoyan las varillas. Está conformado en un solo cuerpo o en dos mitades, generalmente idénticas entre sí, susceptibles de unión in situ o previamente al desplazamiento al lugar de colocación; comprende también un conjunto de nervaduras de refuerzo de la superficie del cuerpo para evitar su deformación. The subject of the present invention is a filling body which is used to occupy the space not subject to stresses in a reinforced concrete slab with metal grills or rods (for example for a slab), which is provided with a set of separating ribs, on which the rods support. It is conformed in a single body or in two halves, generally identical to each other, susceptible of union in situ or previously to the displacement to the place of placement; It also comprises a set of reinforcing ribs of the body surface to prevent its deformation.
Estado de la técnica State of the art
Se conocen distintos dispositivos de aligeramiento de forjados formados por casetones que quedan integrados en el forjado. Ejemplo de ello puede verse en ES2192454, que define un casetón con un cuerpo hueco y una base plana, y medios de unión entre ellos. Different lightening devices are known for slabs formed by cassettes that are integrated into the slab. An example of this can be seen in ES2192454, which defines a cassette with a hollow body and a flat base, and joining means between them.
ES 1071113 U describe un relleno de poliestireno como medio de aligeramiento de los forjados. ES 1071113 U describes a polystyrene filling as a means of lightening the slabs.
Sin embargo, este tipo de rellenos tiene un problema de fabricación y almacenamiento, debido a que se necesita un gran volumen de almacenamiento y transporte, debido a su poco peso. ES1067600 describe un casetón para forjados que, de modo similar al anterior, comprende además unas patas separadoras del suelo. However, this type of fillers has a manufacturing and storage problem, because a large volume of storage and transportation is needed, due to its low weight. ES1067600 discloses a floor slab which, similarly to the previous one, also comprises floor separating legs.
ES 2089947 describe también la construcción de forjados con elementos resistentes de hormigón y aligerados mediante bloques de poliestireno expandido. ES 2089947 also describes the construction of floors with resistant concrete elements and lightened by blocks of expanded polystyrene.
ES 1069999 describe una pieza aplicable para el aligeramiento de losas de hormigón, construida en dos mitades ensamblables entre sí, la cual es susceptible de unión con otras piezas similares a lo largo de una superficie de forjado, estando formada dicha pieza por cuerpos de sección esencialmente cuadrada, con unos lóbulos en cada uno de los ángulos, separados entre sí mediante surcos intermedios, y en la que la armadura se dispone superior e inferiormente al conjunto de la pieza sobre unas plaquillas verticales dispuestas en sentidos diagonales del cuadrado. Esta pieza presenta distintos inconvenientes, y particularmente que por ser de sección cuadrada las tensiones en las direcciones no principales pueden no ser adecuadamente soportadas. Además, no existe aligeramiento en las partes superior e inferior, a la altura de las armaduras, por lo que el coste en hormigón será mayor sin tener por ello una ventaja en cuanto a la resistencia del forjado. ES 1069999 describes a piece applicable for the lightening of concrete slabs, built in two assemblable halves, which it is capable of joining with other similar pieces along a forging surface, said piece being formed by bodies of essentially square section, with lobes in each of the angles, separated from each other by intermediate grooves, and in which the Armor is arranged superiorly and inferiorly to the set of the piece on vertical plates arranged in diagonal directions of the square. This piece presents different drawbacks, and particularly that because of its square section the tensions in the non-main directions may not be adequately supported. In addition, there is no lightening in the upper and lower parts, at the level of the reinforcements, so the cost in concrete will be greater without having an advantage in terms of the strength of the floor.
Por otra parte, el montaje de las mitades exige una de cuatro posiciones de montaje precisas, ya que la forma cuadrada del cuerpo presenta un eje de simetría cuaternario. On the other hand, the assembly of the halves requires one of four precise mounting positions, since the square shape of the body has an axis of quaternary symmetry.
EP2474677 describe un disco de aligeramiento de peso que está formado por un cuerpo esferoide achatado, con una corona central en los lados superior e inferior, en que dicha corona central presenta divisiones a lo largo de su longitud. La corona define lateralmente las posiciones de apoyo de la armadura metálica. Sin embargo, el apoyo de la armadura se realiza directamente sobre la superficie del cuerpo esferoide, por lo que el recubrimiento del conjunto hormigón- armadura, se ve significativamente reducido en la zona de apoyo en el disco, comprometiendo su durabilidad y resistencia. EP2474677 discloses a weight-lightening disc which is formed by a flattened spheroid body, with a central crown on the upper and lower sides, in which said central crown has divisions along its length. The crown laterally defines the support positions of the metal framework. However, the reinforcement of the reinforcement is made directly on the surface of the spheroid body, so that the coating of the concrete-reinforcement assembly is significantly reduced in the support area on the disc, compromising its durability and resistance.

Cuando son dos mitades, una vez montadas define un cuerpo hueco. The present invention proposes a lightening device for concrete slabs, having a spheroidal shape and a positioning element of the reinforcement, is formed in two identical halves that allow their assembly in virtually any angular position, or in a single piece, and has ribs emerging from the positioning element that define a support for the reinforcement, so that the concrete surrounds the rods adequately without impairing the strength and durability.

Descripción detallada de los modos de realización Detailed description of the embodiments
Se describe la presente invención como un cuerpo de relleno (1), que presenta forma esferoide, normalmente con una porción lateral, sustancialmente vertical (cilindrica), y una porción superior sustancialmente horizontal, que está formado por dos semicuerpos (2), realizados en inyección o soplado de material plástico. Los dos semicuerpos son preferentemente idénticos entre sí, y comprenden medios de unión entre uno y otro semicuerpo. Dichos medios de unión se distribuyen regularmente a distancias angulares regulares o irregulares, y pueden alternar elementos macho con elementos hembra, de modo que la unión entre uno y otro semicuerpo (2) puede realizarse en una de muchas posiciones angulares relativas. Sin carácter limitativo, los medios de unión de los semicuerpos (2) pueden ser: The present invention is described as a filler body (1), which has a spheroidal shape, usually with a lateral portion, substantially vertical (cylindrical), and a substantially horizontal upper portion, which is formed by two half-bodies (2), made in injection or blowing of plastic material. The two half-bodies are preferably identical to each other, and comprise joining means between one and the other half-body. Said joining means they are distributed regularly at regular or irregular angular distances, and can alternate male elements with female elements, so that the connection between one and the other half-body (2) can be made in one of many relative angular positions. Without limitation, the means of joining the half-bodies (2) can be:
Un machihembrado; A tongue and groove;
Porciones roscadas; Threaded portions;
Un cierre de bayoneta; A bayonet closure;
Unión a presión. Pressure joint.
La superficie superior (o inferior, en el semicuerpo opuesto) del semicuerpo (2) está provista de un elemento de posicionamiento. De acuerdo con un primer modo de realización, se dispone un elemento de posicionamiento (5) en forma anular o de corona de altura continua, en la porción horizontal del cuerpo de aligeramiento (1), alrededor del eje de simetría en el casquete esferoide superior (o inferior). En este caso, la corona anular deja interiormente un hueco sustancialmente cilindrico que será rellenado con el hormigón cuando se vierta sobre el encofrado correspondiente. The upper surface (or lower, in the opposite half-body) of the half-body (2) is provided with a positioning element. According to a first embodiment, a positioning element (5) in ring or annular form of continuous height is provided in the horizontal portion of the lightening body (1), around the axis of symmetry in the upper spheroid cap (or lower). In this case, the annular crown internally leaves a substantially cylindrical recess that will be filled with the concrete when it is poured over the corresponding formwork.
De acuerdo con un segundo modo de realización el elemento de posicionamiento (6) está formado por un conjunto de quesitos (8), con vértice orientado hacia el eje de simetría. Dichos quesitos presentan una concavidad (7) de profundidad progresiva hasta confundirse con la superficie en la zona próxima al eje de simetría. La curvatura de dicha concavidad presenta la ventaja de suponer un apoyo resistente del hormigón, mayor cuanto más al centro, y menor cuanto más hacia la periferia, y se encuentra reforzado por los espacios existentes entre cada pareja de quesitos (8). According to a second embodiment, the positioning element (6) is formed by a set of chests (8), with vertex oriented towards the axis of symmetry. Said cheeses have a concavity (7) of progressive depth until they are confused with the surface in the area close to the axis of symmetry. The curvature of said concavity has the advantage of supposing a resistant support of the concrete, greater the more to the center, and the lower the more towards the periphery, and is reinforced by the spaces existing between each pair of cheeses (8).
Sobre la superficie del cuerpo de relleno, en zonas próximas al elemento de posicionamiento (5,6) se disponen un conjunto de nervaduras de apoyo (3) en posición radial, que se disponen de forma sobreelevada respecto a la superficie del cuerpo de relleno (1). Según una primera opción (figura 8) dichas nervaduras consisten en sendas placas conformadas sobre la superficie de dicho cuerpo de relleno (1); designamos con (31) la sección según dicha primera opción. Según una segunda opción, que se representa en la figura 9, y designa con (32), las nervaduras están conformadas por la deformación de la superficie de dicho cuerpo de relleno (1) en forma angular. Las nervaduras presentan al menos una porción sustancialmente horizontal, cuyo borde superior se encuentra alineado con la base del elemento de posicionamiento (5,6), de modo que dicho elemento de posicionamiento (5,6) emerge con respecto a la altura de dichas nervaduras de apoyo (3). On the surface of the filling body, in areas close to the positioning element (5,6) a set of support ribs (3) in radial position, which are arranged in an elevated manner with respect to the surface of the filling body (1). According to a first option (figure 8) said ribs consist of respective plates formed on the surface of said filling body (1); we designate with (31) the section according to said first option. According to a second option, which is represented in Figure 9, and designated by (32), the ribs are formed by the deformation of the surface of said filler body (1) in an angular manner. The ribs have at least a substantially horizontal portion, whose upper edge is aligned with the base of the positioning element (5,6), so that said positioning element (5,6) emerges with respect to the height of said ribs of support (3).
Además, para poder minimizar la cantidad de masa de material empleada para la realización del cuerpo de relleno (1), se disponen un conjunto de nervaduras resistentes (4). Estas nervaduras pueden estar realizadas, al igual que las de apoyo (3) por conformación de una placa sobre la superficie (interior o exterior) del cuerpo de relleno (1), o por deformación de la superficie de dicho cuerpo de relleno (1). In addition, in order to minimize the amount of material mass used to make the filling body (1), a set of resistant ribs (4) are arranged. These ribs can be made, as well as the support ribs (3) by forming a plate on the surface (interior or exterior) of the filling body (1), or by deformation of the surface of said filling body (1) .
Las nervaduras resistentes (4) pueden definirse en solución de continuidad con las nervaduras de apoyo (3) y/o de forma independiente de éstas. The resistant ribs (4) can be defined in continuity with the support ribs (3) and / or independently of these.
Conforme a un tercer modo de realización, se define un elemento de posicionamiento con una porción sobreelevada (33) de las nervaduras de apoyo (3) en su parte más próxima al centro. Según este modo de realización, las varillas estructurales apoyarán sobre la nervaduras de apoyo (3) distanciadas del cuerpo hueco una cierta distancia que permitirá que sean totalmente recubiertas de hormigón, y al mismo tiempo será la propia nervadura la que determine mediante su porción sobreelevada (33) el límite o posición que deberá adoptar dicha varilla previamente al vertido del hormigón, todo ello permitiendo también un flujo de la masa de hormigón también en las partes centrales de los cuerpos huecos. According to a third embodiment, a positioning element with an elevated portion (33) of the support ribs (3) is defined in its part closest to the center. According to this embodiment, the structural rods will rest on the support ribs (3) spaced apart from the hollow body a certain distance that will allow them to be completely covered with concrete, and at the same time it will be the rib itself that determines by its raised portion ( 33) the limit or position that said rod must adopt prior to the pouring of the concrete, all this also allowing a flow of the concrete mass also in the central parts of the hollow bodies.
Obviamente, las nervaduras de apoyo tienen también una función resistente. Obviously, the supporting ribs also have a resistant function.
De forma preferente el número de nervaduras radiales es no inferior a ocho, ni superior a veinticuatro, variable según la longitud de las mismas, con un número óptimo de dieciséis. Preferably, the number of radial ribs is not less than eight, nor more than twenty-four, variable according to the length thereof, with an optimum number of sixteen.
Mediante la utilización de estos cuerpos de relleno se obtienen estructuras más seguras, baratas y/o resistentes que las descritas en los antecedentes. By using these filler bodies, safer, cheaper and / or more resistant structures are obtained than those described in the background.
