Abstract

"APERFEIçOAMENTO DE PERFIL DE AçO ZINCADO UTILIZADO COMO FÈRMA INCORPORADA AO CONCRETO FORMANDO LAJE MISTA". A fórma de pequena altura desenvolvida tem o objetivo de possibilitar a execução de lajes com espessuras menores que aquelas fabricadas com os 'decks' metálicos existentes, permitindo que se obtenha menor peso próprio para os pisos. As fórmas de aço desenvolvidas são moldadas em chapas de aço zincado, com altura base de 60mm, definindo basicamente mesa superior (1) e mesa inferior (2), dotadas de dois enrijecimentos longitudinais, uma de suas vantagens, podendo ser enrijecedores em 'V' (9), ou combinados, ou seja, enrijecedores em 'V' (9), nas mesas inferiores, e enrijecedores reentrantes (10) nas mesas superiores (1). As mesas superiores (1) e inferiores (2) são interligadas por almas (11). Ambas apresentam estampadas em toda sua extensão, mossas em 'V' (12) ou transversais (13), mais eficientes que as mossas adotadas nos 'decks' metálicos existentes. O emprego dessas fórmas proporciona grande economia na construção civil, pela redução significativa no prazo de execução, diminuição nos desperdícios de materiais e no custo de mão-de-obra, o que torna a relação custo/benefício de interesse imediato na construção civil.
