DESCRIÇÃO DESCRIPTION
ELEMENTO DE COFRAGEM E SISTEMA DE COFRAGEM PARA ELEMENTOSFORMWORK ELEMENT AND FORMWORK SYSTEM FOR ELEMENTS
ESTRUTURAIS STRUCTURAL
Âmbito da Invenção Scope of Invention
A presente invenção enquadra-se no campo da construção civil, mais especificamente a um elemento para realização de cofragens perdidas, mais concretamente a uma peça de acabamento que serve de cofragem definitiva autoportante e de acabamento para elementos estruturais de betão, que fica integrada no elemento estrutural. The present invention is part of the field of civil construction, more specifically to an element for the realization of lost formwork, more specifically to a finishing part that serves as a self-supporting definitive formwork and finishing for structural concrete elements, which is integrated into the element. structural.
Enquadramento da invenção Context of the invention
Na construção civil, quando é necessário executar uma estrutura vertical, como por exemplo: paredes, muros, pilares ou núcleos de elevador, é necessário proceder à montagem de uma estrutura de suporte, geralmente em metal, madeira, plástico ou outro material menos comum, com o propósito de evitar desmoronamentos ou para delimitar e reter betão como numa espécie de reservatório, o que garante que através de uma estrutura estanque, que a estrutura mantém o formato até à sua completa secagem ou solidificação. In civil construction, when it is necessary to carry out a vertical structure, such as: walls, walls, pillars or elevator cores, it is necessary to assemble a supporting structure, usually in metal, wood, plastic or other less common material, with the purpose of preventing collapses or to delimit and retain concrete as in a kind of reservoir, which ensures that through a watertight structure, that the structure maintains its shape until its complete drying or solidification.
Estas estruturas designadas por cofragens, apresentam a desvantagem de, após a estrutura se encontrar seca ou solidificada, ter que ser desmontada. These structures, called formworks, have the disadvantage that, after the structure is dry or solidified, it has to be dismantled.
Antecedentes da Invenção Background of the Invention
Foram encontrados alguns documentos que fazem referência a elementos para a realização de cofragens. Refira-se nomeadamente o documento EP0757137 que apresenta uma cofragem para produção de estruturas para obtenção de painéis prefabricados para revestimentos de fachadas. Some documents were found that refer to elements for the realization of formwork. Reference should in particular be made to document EP0757137 which presents a formwork for the production of structures for obtaining prefabricated panels for covering facades.
Refira-se ainda o documento WO0222982 que divulga um painel de cofragem fabricado num material isolante e que incorpora um núcleo metálico reforçado. Reference should also be made to the document WO0222982 which discloses a formwork panel made of an insulating material and which incorporates a reinforced metallic core.
Ou ainda o documento EP1434919 que apresenta painéis ocos ligados entre si para realização de uma cofragem. Or even the document EP1434919 which presents hollow panels connected together to form a formwork.
Não foi contudo encontrado nenhum documento que refira uma solução para uma cofragem definitiva para elementos estruturais de betão que fique integrada no elemento estrutural e que em simultâneo sirva de acabamento dessa mesma estrutura. However, no document was found that mentions a solution for a definitive formwork for concrete structural elements that is integrated into the structural element and that simultaneously serves as a finishing of that same structure.
Vantagens da Invenção Advantages of the Invention
Atualmente o método mais comum utilizado para a execução de estruturas de betão armado é a cofragem dita tradicional, o que implica a utilização de vários sistemas de cofragem, com tudo o que essa prática implica, como a utilização de óleos descofrantes, espaçadores para garantia de recobrimento, já que, uma vez concluída a tarefa, se seguirá a respetiva desmontagem da cofragem e limpeza da mesma, bem como a necessidade de correção de imperfeições resultantes de betonagem. Currently, the most common method used for the execution of reinforced concrete structures is the so-called traditional formwork, which implies the use of various formwork systems, with all that this practice implies, such as the use of release oils, spacers to guarantee covering, since, once the task is completed, the formwork will be dismantled and cleaned, as well as the need to correct imperfections resulting from concreting.
Existe também a necessidade da criação de negativos nos vários elementos para escoramento das cofragens que de seguida têm de ser selados, ou então usar peças de elevado custo para que essa selagem seja garantida. There is also the need to create negatives in the various elements for shoring the formwork that then have to be sealed, or else to use high-cost parts so that this sealing is guaranteed.
> Na solução apresentada neste documento, é a própria peça de acabamento que serve de cofragem e acabamento para os elementos estruturais e garantem o recobrimento dos mesmos, assim como o acabamento final dos elementos a betonar, podendo ser de betão branco ou com corantes, assim como com classes de exposição adequadas ao local onde se insere a obra, o que confere a esta solução uma elevada versatilidade nos acabamentos. > In the solution presented in this document, it is the finishing part itself that serves as formwork and finishing for the structural elements and guarantees their covering, as well as the final finish of the elements to be concreted, which can be of white concrete or with dyes, as well as with exposure classes appropriate to the place where the work is located, which gives this solution a high versatility in finishes.
