Description
Forjado mixto de poliestireno y hormigón.Mixed forging of polystyrene and concrete.
La presente invención tiene por objeto un forjado mixto de poliestireno y hormigón en base a casetones o bovedillas macizos de poliestireno a los que en posición invertida se les aplica una soleta de hormigón, con lo que al producto una vez instalado en obra se le puede aplicar directamente la capa de enlucido sin riesgo de fisuras.The present invention aims at a mixed forging of polystyrene and concrete based on cassettes or solid polystyrene vaults to those in an inverted position a concrete slab is applied, which gives the product a Once installed on site you can directly apply the layer of plastered without risk of cracks.
Los casetones o bovedillas se pueden conformar a partir de semicasetones y semibovedillas aligerados respectivamente, que presentan una alta resistencia a la flexión debido a un tabique central de mayor espesor existente en los mismos.The cases or vaults can conform to from lightened half-shells and semi-vaults respectively, which have high flexural strength due to a thicker central partition existing in the same.
Además, debido a la especial configuración de los casetones y bovedillas, ya sean macizos o aligerados, se pueden dividir en dos según una dirección perpendicular a la superficie de unión de las dos semibovedillas o los dos semicasetones aligerados, siendo de gran utilidad en obra debido al elevado número de semielementos que se utilizan.In addition, due to the special configuration of the cases and vaults, whether solid or lightened, can be divide in two according to a direction perpendicular to the surface of union of the two semi-vaults or the two lightened half-sets, being very useful on site due to the high number of semi-elements that are used.
Son sobradamente conocidos en el estado de la técnica las bovedillas o los casetones de poliestireno expandido que se emplean para conformar forjados unidireccionales o bidireccionales respectivamente.They are well known in the state of technique the vaults or the cases of expanded polystyrene which are used to form unidirectional slabs or bidirectional respectively.
Sin embargo, en los forjados anteriores es frecuente la aparición de fisuras debido al diferente coeficiente de dilatación con el del hormigón que va situado entre las bovedillas o casetones.However, in the previous slabs it is frequent the appearance of fissures due to the different coefficient of expansion with that of the concrete that is located between the vaults or casetones.
Por otra parte, en los anteriores forjados los elementos suspendidos pesados solamente pueden ser fijados directamente a la estructura, además de que el forjado así conformado presenta un pobre aislamiento acústico.On the other hand, in the previous ones forged the heavy suspended elements can only be fixed directly to the structure, in addition to the floor as well shaped presents a poor sound insulation.
También son conocidos los forjados construidos a base de cubetas recuperables que son adecuados para techos de garajes o edificios industriales que no necesitan pintura o recubrimiento posterior.Also forged are built to base of recoverable cuvettes that are suitable for roofs of garages or industrial buildings that do not need paint or back cover.
En estos sistemas, al no poder aplicar el enlucido directamente, es necesario colocar un falso techo con los consiguientes costes asociados a esta colocación.In these systems, unable to apply the plastered directly, it is necessary to place a false ceiling with the consequent costs associated with this placement.
Todos los inconvenientes anteriores quedan superados mediante la invención que ahora se procede a describir debido a la presencia de un forjado que lleva incorporado una soleta de hormigón antes de su instalación en obra que permite aplicar directamente un enlucido y donde el fijado de cargas se puede hacer en cualquier parte del forjado.All the above problems remain overcome by the invention that is now described due to the presence of a floor that incorporates a concrete slab before installation on site that allows apply a plaster directly and where the load setting is It can be done anywhere on the floor.
La presente invención se refiere a un forjado mixto de poliestireno y hormigón formado a partir de casetones o bovedillas que se colocan en posición invertida para aplicarles una soleta de hormigón, de manera que al fraguar el hormigón, la soleta queda firmemente anclada al casetón o bovedilla de poliestireno expandido.The present invention relates to a floor mixed polystyrene and concrete formed from casetones or vaults that are placed in an inverted position to apply a concrete slab, so that when setting the concrete, the slab is firmly anchored to the polystyrene vault or vault expanded.
Los casetones o bovedillas pueden ser macizos o se pueden formar a partir de semicasetones o semibovedillas aligerados obtenidos en un molde, donde estos, tras el desmoldeo son enfrentados entre sí dando lugar a casetones o bovedillas completos.The cases or vaults can be solid or they can be formed from semi-sets or semi-vaults lightened obtained in a mold, where these, after the demoulding they are faced with each other giving rise to casetones or vaults complete.
El ensamblaje de ambos semicasetones o semibovedillas se realiza mediante el guiado que proporcionan unos tetones existentes en cada uno de los semicasetones o de las semibovedillas que se insertan en unos orificios antagonistas del semicasetón o semibovedilla opuestos.The assembly of both half-sets or Semi-vaults are made through the guidance provided by some existing lugs in each of the half-sets or of the semi-vaults that are inserted into antagonistic holes of the Semi-seton or half-vase opposite.
Tanto en los casetones o bovedillas macizos, como en los casetones o bovedillas aligerados, donde el tabique central presenta un mayor espesor que aumenta la resistencia a la flexión, el casetón o bovedilla se anclan mediante un canal existente en su parte superior a la capa de compresión del forjado.Both in the casetones or solid vaults, as in lighter cases or vaults, where the partition central has a greater thickness that increases resistance to bending, the cassette or vault are anchored by a channel existing at the top of the compression layer of the wrought.
Así mismo, los casetones o bovedillas macizos, y los casetones o bovedillas aligerados se pueden dividir en dos siendo de gran utilidad en obra debido al elevado número de semielementos que se utilizan.Likewise, the solid cases or vaults, and the lighted cases or vaults can be divided into two being very useful on site due to the high number of semi-elements that are used.
En los casetones o bovedillas aligerados el
tabique central de mayor espesor permite dividir en dos la
bovedilla o el casetón según una dirección perpendicular a la
superficie de unión de las dos semibovedillas o los dos
semi-
casetones.In lightened cases or vaults, the thicker central partition allows the vault or the case to be divided in two according to a direction perpendicular to the junction surface of the two semi-vaults or the two semi-
casetones
Así mismo, el casetón o la bovedilla pueden presentar huecos y resaltes que sirven de asideros para su transporte.Likewise, the caseton or vault can present holes and projections that serve as handles for your transport.
La zona del casetón o de la bovedilla que está en contacto con la soleta de hormigón puede presentar un rehundido que proporciona la separación mínima para garantizar el recubrimiento de las barras de ferralla que se colocan en esa zona entre los casetones o las bovedillas, con lo que el ahorro de hormigón vertido en la parte superior del forjado es considerable además de la disminución del peso propio del mismo.The area of the box or the vault that is in contact with the concrete slab may have a recess which provides the minimum separation to guarantee the coating of the ferralla bars that are placed in that area between the cases or vaults, thus saving concrete poured on the top of the floor is considerable in addition to the decrease of the own weight of the same.
Así mismo, este rehundido permite el apoyo de los casetones o las bovedillas en las vigas del forjado.Likewise, this sunken allows the support of the boxes or vaults on the beams of the floor.
Las bovedillas presentan salientes y orificios antagonistas en sus extremos para realizar el ensamblaje en obra y conformar el forjado unidireccional.The vaults have protrusions and holes antagonists at their ends to perform assembly on site and conform the unidirectional floor.
