Description

Sistema que comprende una viga, una lámina corrugada y un conector System comprising a beam, a corrugated sheet and a connector

La presente invención se refiere a un sistema que comprende una viga, una lámina trapezoidal corrugada y un conector en dicha lámina trapezoidal corrugada. The present invention relates to a system comprising a beam, a corrugated trapezoidal sheet and a connector in said corrugated trapezoidal sheet.

Un caso típico del uso de esta clase de sistema es aquel que soporta una losa de hormigón. El conector ejerce principalmente una resistencia contra el movimiento horizontal entre la viga subyacente y la losa. Además, el conector está modelado de tal manera que resiste fuerzas de separación verticales entre la viga y la losa. A typical case of using this kind of system is one that supports a concrete slab. The connector mainly exerts a resistance against horizontal movement between the underlying beam and the slab. In addition, the connector is modeled in such a way that it resists vertical separation forces between the beam and the slab.

Como se conoce en la industria de la construcción a menudo aparece el problema relativo a la conexión apropiada entre las vigas de acero y una losa de hormigón. Las vigas de acero se refieren como primarias o secundarias dependiendo de su importancia desde un punto de vista estático en la industria de la construcción. La estructura de la sección transversal de estas vigas puede ser extremadamente variada y, estrictamente con fines ilustrativos, en lo sucesivo sólo se mencionan vigas IPE o HE. En la parte superior, las vigas están cubiertas con una capa de hormigón y así existe la posibilidad de proporcionar fijación recíproca entre la viga y el hormigón en sí. As is known in the construction industry, the problem often arises regarding the proper connection between the steel beams and a concrete slab. Steel beams are referred to as primary or secondary depending on their importance from a static point of view in the construction industry. The cross-sectional structure of these beams can be extremely varied and, strictly for illustrative purposes, hereafter only IPE or HE beams are mentioned. At the top, the beams are covered with a concrete layer and thus there is the possibility of providing reciprocal fixing between the beam and the concrete itself.

En realidad, en casos en que no se proporciona el rendimiento de esta clase de conexiones, se requeriría que las vigas estuvieran hechas con dimensiones muy superiores, lo cual implicaría costes más elevados para la fabricación de estructuras que comprenden las vigas en sí. En la práctica, es posible asegurar la conexión entre el acero y el material de hormigón y reducir considerablemente la cantidad de acero usada al mismo tiempo, lo que lleva en consecuencia a ventajas en términos de reducción tanto de los costes de fabricación como de las dimensiones globales de la estructura. In fact, in cases where the performance of this kind of connections is not provided, the beams would be required to be made with much larger dimensions, which would imply higher costs for the manufacture of structures comprising the beams themselves. In practice, it is possible to ensure the connection between the steel and the concrete material and considerably reduce the amount of steel used at the same time, which leads accordingly to advantages in terms of reducing both manufacturing costs and dimensions Global structure.

En ocasiones, en la parte superior de las vigas se proporcionan láminas metálicas, del tipo denominado corrugado trapezoidal, dado que tienen surcos y relieves alternos; en particular, se proporcionan para que el hormigón se aplique sobre las láminas, que terminan así interpuestas entre el hormigón y las vigas. Así, cuando se usan láminas corrugadas trapezoidales, se requiere fijación recíproca entre la viga de acero subyacente y la losa de hormigón a través de la lámina corrugada trapezoidal. Sometimes metal sheets, of the type called trapezoidal corrugated, are provided at the top of the beams, since they have alternate grooves and reliefs; in particular, they are provided so that the concrete is applied on the sheets, which thus end up interposed between the concrete and the beams. Thus, when trapezoidal corrugated sheets are used, reciprocal fixing between the underlying steel beam and the concrete slab through the trapezoidal corrugated sheet is required.

Con el fin de permitir estas conexiones se han inventado muchos tipos de conectores, entre los cuales el descrito en el documento EP-A-0.504.500, del mismo solicitante, que se refiere a un conector-pasador provisto de una placa de fijación y espárragos o cualquier otro material de fijación. In order to allow these connections, many types of connectors have been invented, among which the one described in EP-A-0.504.500, of the same applicant, which refers to a connector-pin provided with a fixing plate and studs or any other fixing material.

El documento EP-A-0.504.500 desvela un sistema según el preámbulo de la reivindicación 1. Document EP-A-0.504.500 discloses a system according to the preamble of claim 1.

Otros conectores del estado de la técnica se describen en los documentos EP-1.582.644-A1; DE-38/20.476-A1; JP62/154.042-U y DE-20/23.635-A1. Other prior art connectors are described in EP-1,582,644-A1; DE-38 / 20.476-A1; JP62 / 154.042-U and DE-20 / 23.635-A1.

El objetivo de la presente invención es proporcionar un sistema que comprende un conector del tipo descrito anteriormente, fácil de montar y también más resistente una vez montado, con respecto a conectores similares del tipo conocido. The object of the present invention is to provide a system comprising a connector of the type described above, easy to assemble and also more resistant once mounted, with respect to similar connectors of the known type.

Según la invención, esto se consigue proporcionando un sistema según la reivindicación 1. According to the invention, this is achieved by providing a system according to claim 1.

El conector en dicho sistema es capaz de adaptarse a la presencia de barras rectas o en U, para reforzar la conexión con el hormigón, que se dispondrá en proximidad con los extremos superiores de dichos bordes laterales, y también a la presencia de posibles nervaduras (referidas habitualmente como salientes) en la parte inferior de las láminas corrugadas trapezoidales. The connector in said system is capable of adapting to the presence of straight or U-bars, to reinforce the connection with the concrete, which will be arranged in proximity to the upper ends of said lateral edges, and also to the presence of possible ribs ( usually referred to as protrusions) in the lower part of the trapezoidal corrugated sheets.

Estas y otras características de la invención se describirán en detalle a continuación, con referencia a algunas de sus formas de realización en particular, proporcionadas con fines ilustrativos, con la ayuda de los dibujos adjuntos en los que: These and other features of the invention will be described in detail below, with reference to some of their particular embodiments, provided for illustrative purposes, with the aid of the accompanying drawings in which:

En la fig. 21 (lámina VII) se representa el sistema de la invención que comprende una pluralidad de conectores, aplicados de diversas formas en vigas provistas también de una lámina corrugada trapezoidal.  In fig. 21 (sheet VII) represents the system of the invention comprising a plurality of connectors, applied in various ways to beams also provided with a trapezoidal corrugated sheet.

En las figs. 1 a 5 puede observarse que el conector, indicado generalmente por 100, tiene una base de forma sustancialmente rectangular 1, que puede fijarse contra una viga (posiblemente a través de una lámina interpuesta), a través de uno o más espárragos 2 u otros elementos de conexión fija equivalentes. Desde dicha base se levantan dos bordes laterales de forma sustancialmente plana 3 dispuestos en oblicuo con respecto a la base mencionada anteriormente, de tal manera que se ensanchan al moverse desde la base hacia arriba. Ventajosamente en la cara superior de los bordes laterales 3 se proporcionan algunas ranuras 4 provistas de un extremo ensanchado 4’, para permitir la inserción de una varilla metálica 5 (véanse las figs. 6 a 10) en el interior de la misma, que servirá como un elemento de refuerzo para el hormigón; la inserción está concebida de una forma tal que la varilla no puede desalojarse durante la etapa de ejecución, ni durante la etapa operativa cuando el conector ejerce su resistencia contra el movimiento horizontal entre la losa y la viga. In figs. 1 to 5 it can be seen that the connector, generally indicated by 100, has a substantially rectangular base 1, which can be fixed against a beam (possibly through an interposed sheet), through one or more studs 2 or other elements Fixed connection equivalents. From said base two substantially flat side edges 3 are raised obliquely with respect to the aforementioned base, such that they widen as they move from the base upwards. Advantageously, some grooves 4 are provided on the upper face of the side edges 3 provided with a widened end 4 ', to allow the insertion of a metal rod 5 (see Figs. 6 to 10) inside it, which will serve as a reinforcing element for concrete; The insert is designed in such a way that the rod cannot be dislodged during the execution stage, or during the operational stage when the connector exerts its resistance against horizontal movement between the slab and the beam.

Como puede observarse en la fig. 19, el conector objeto de la invención estará fijado directamente contra una lámina corrugada trapezoidal 7. La lámina corrugada trapezoidal 7 está provista de un saliente 8 en la parte inferior de sus surcos y, para permitir la fijación del conector contra la lámina, se proporciona que la parte inferior 1 de la base sea ventajosamente ondulada 9, con el fin de adaptarse al saliente correspondiente de la lámina corrugada trapezoidal; además, se proporciona ventajosamente en la superficie interior del conector una nervadura de refuerzo 10. As can be seen in fig. 19, the connector object of the invention will be fixed directly against a trapezoidal corrugated sheet 7. The trapezoidal corrugated sheet 7 is provided with a projection 8 at the bottom of its grooves and, to allow the connector to be fixed against the sheet, it is provided that the lower part 1 of the base is advantageously corrugated 9, in order to adapt to the corresponding projection of the trapezoidal corrugated sheet; furthermore, a reinforcement rib 10 is advantageously provided on the inner surface of the connector.

Por otra parte, las figs. 11 a 14 muestran que la fijación de la base 1 a la lámina corrugada trapezoidal requerirá al menos un punto de fijación, a través de espárragos 2 u otros medios de conexión, aunque los mejores resultados se obtendrán por medio de un par de espárragos, según se ilustra en la fig. 11. On the other hand, figs. 11 to 14 show that fixing the base 1 to the trapezoidal corrugated sheet will require at least one fixing point, through studs 2 or other connection means, although the best results will be obtained by means of a pair of studs, according to It is illustrated in fig. eleven.

Como puede observarse en las figs. 15 y 16 el dispositivo objeto de la presente invención se usará ventajosamente para conexión directa entre el hormigón 11 y la viga 6; este sistema no forma parte de la invención reivindicada. Dentro del hormigón se proporcionan nervaduras de refuerzo 5. As can be seen in figs. 15 and 16 the device object of the present invention will be advantageously used for direct connection between the concrete 11 and the beam 6; This system is not part of the claimed invention. Inside the concrete reinforcement ribs 5 are provided.

La fig. 17 muestra que el conector se usa en un sistema, en el que se proporciona una lámina corrugada trapezoidal 7 y en este sistema el conector se fijará contra la viga 6 pasando a través de la lámina corrugada trapezoidal. Fig. 17 shows that the connector is used in a system, in which a trapezoidal corrugated sheet 7 is provided and in this system the connector will be fixed against the beam 6 passing through the trapezoidal corrugated sheet.

Las figs. 18 a 20 muestran que el conector está adaptado para ser aplicado a varias formas de una lámina corrugada trapezoidal 7; obviamente, la estructura de la base 1 del conector variará dependiendo del saliente 8 si se proporciona en dicha lámina corrugada trapezoidal. Figs. 18 to 20 show that the connector is adapted to be applied to various shapes of a trapezoidal corrugated sheet 7; obviously, the structure of the connector base 1 will vary depending on the projection 8 if it is provided on said trapezoidal corrugated sheet.
