La invención que se presenta aporta la principal ventaja de la calidad de la construcción ya que este tipo de anclaje entre pilares esta perfectamente tipificado en la normativa actual, a través de las longitudes de empalme por solape.The invention presented provides the main advantage of construction quality since this type of anchoring between pillars is perfectly typified in the regulations current, through overlap splice lengths.
En la actualidad los edificios para viviendas y para otros usos, generalmente están constituidos por estructuras de hormigón armado, que en la mayoría de los casos, son realizadas en la propia obra mediante diferentes tipos de encofrados, dentro de los cuales se sitúan los armados de hierro que previamente han sido preparados en talleres especializados en ferralla, y que finalmente se rellenan de hormigón.At present the buildings for houses and for other uses, they are generally constituted by structures of reinforced concrete, which in most cases, are made in the work itself through different types of formwork, within which are located iron armed that have previously been prepared in specialized workshops in ferralla, and finally They are filled with concrete.
También son utilizados a veces ciertos sistemas de unión de pilares prefabricados, consistentes en rellenar un hueco preferentemente cónico, situado en la base del pilar, el cual presenta en su cara de adherencia con el relleno, unos salientes que propician únicamente esfuerzos rasantes cuando queda fraguado el relleno de unión que se aporta.Sometimes certain systems are also used of union of prefabricated pillars, consisting of filling a preferably conical hollow, located at the base of the pillar, which it presents on its face of adhesion with the filling, some projections that only favor flush efforts when it is set the joint filler that is provided.
Los pilares que se integran en las construcciones y que se conforman "in situ" tienen el inconveniente de ralentizar el ritmo de levantamiento de la obra, ya que como es sabido, resulta muy laboriosa la preparación de los encofrados, así como la situación de la ferralla en su interior, para finalmente realizar el hormigonado.The pillars that are integrated in the constructions and that are conformed " in situ " have the disadvantage of slowing the pace of lifting of the work, since as it is known, it is very laborious the preparation of the formwork, as well as the situation of the ferralla inside, to finally perform the concreting.
Otros inconvenientes del hormigonado de pilares en obra, consisten en la importante inversión económica que se precisa en lo referente a los elementos que son necesarios para la ejecución del encofrado.Other disadvantages of concrete concreting on site, they consist of the important economic investment that precise in relation to the elements that are necessary for the formwork execution.
Los pilares prefabricados conocidos, presentan
el problema del control de la calidad, ya que la transmisión de
esfuerzos entre el hormigón vertido en obra y la cara del
prefabricado, se produce de forma rasante, lo cual implica, la
obligación de tener que realizar ensayos sistemáticos que
garanticen que la cara conseguida en los pilares, se corresponda con
la
ensayada.The known prefabricated pillars, present the problem of quality control, since the transmission of efforts between the concrete poured on site and the face of the prefabricated, occurs flush, which implies, the obligation to have to perform systematic tests that guarantee that the face achieved in the pillars corresponds to the
rehearsed
Como problema citaremos finalmente, el tema económico, pues una obra con estructuras de hormigón armado, realizada por medios tradicionales, resulta sensiblemente más costosa que la que integra elementos estructurales prefabricados.As a problem we will finally quote the subject economic, because a work with reinforced concrete structures, done by traditional means, it is noticeably more expensive than the one that integrates structural elements prefabricated
Para solventar la problemática existente en la actualidad se ha ideado el sistema mejorado de pilar prefabricado objeto de la presente invención, caracterizado por preverse en el referido pilar prefabricado un elemento de sección y longitud variable de hormigón armado, emergiendo de su base superior una parte de la armadura metálica, lo que permite su unión con las vigas de la planta a la que da soporte, así como su anclaje con el pilar que nace de la planta, al preverse una oquedad en la base del pilar prefabricado. La referida oquedad en la base del pilar prefabricado aloja parte de la armadura metálica que proporcionará la unión entre pilares por solape, previéndose en la parte superior de la citada oquedad una ventana o conducto para permitir el hormigonado del hueco, lo que permitirá la unión entre pilares.To solve the problem in the The improved precast pillar system has been devised today object of the present invention, characterized by being provided in the referred to prefabricated pillar an element of section and length variable concrete, emerging from its upper base a part of the metal armor, which allows its union with the beams of the plant it supports, as well as its anchoring with the pillar that is born from the plant, when a hollow at the base of the prefabricated pillar. The aforementioned cavity at the base of the pillar prefabricated houses part of the metal armor that will provide the union between pillars by overlapping, provided at the top of the aforementioned recess a window or conduit to allow the concreting of the hole, which will allow the union between pillars.
El sistema mejorado de pilar prefabricado que se presenta, tiene múltiples ventajas sobre los medios y sistemas conocidos en la actualidad, destacándose principalmente, el tema de la calidad de la construcción ya que este tipo de anclaje entre pilares esta perfectamente tipificado en la normativa actual, a través de las longitudes de empalme por solape.The improved prefabricated abutment system that presents, has multiple advantages over media and systems known today, standing out mainly, the subject of the quality of the construction since this type of anchor between pillars is perfectly typified in current regulations, to through overlap splice lengths.
Otra ventaja consiste en que se aumenta el ritmo en la elevación de la obra, lo cual proporciona unos menores costes.Another advantage is that the pace is increased in the elevation of the work, which provides some minor costs
Otra ventaja supone la facilidad de su colocación en lugares complejos como medianiles y otros casos, ya que su colocación en obra es con la resistencia adquirida.Another advantage is the ease of your placement in complex places such as medians and other cases, since that its placement on site is with the resistance acquired.
Finalmente citaremos como ventaja su gran versatilidad, tanto en longitud como en sección, ya que éstas, pudiendo adoptar cualquier forma, optimizan las estructuras a construir.Finally we will cite as an advantage its great versatility, both in length and in section, since these, being able to take any form, they optimize the structures to build.
