Abstract
ESTRUTURAS CONSTRUTIVAS RìGIDAS PRESSURIZADAS COM GASES (PROTENSãO BIDIRECIONAL) E SUAS APLICAçõES. Patente de invenção de um singular sistema de estruturas extremamente rígidas em diferentes formatos que não se alteram com pressões internas, tais como: formas cilíndricas de tubos e dutos (Fig.0 1), formas cilíndricas ovóides (Fig. 02), toros (Fig. 03) e esferas, confeccionados em diferentes espessuras, tamanhos e materiais, tais como: alumínio, duraluminio, aços, fibra de vidro, fibra de carbono, Kevlar(r) ou composit (materiais compostos e reforçados), sendo internamente pressurizados e protendidos com gases, como Hélio, Hidrogênio, ar comprimido e outros, fechados e lacrados com tampas (13) em suas extremidades, no caso de formas cilíndricas de tubos e dutos e tubos ovóides, podendo chegar a ter peso total menor que zero, contando opcionalmente com sacos flexíveis (5) em seu interior, também pressurizados, como medida de segurança (Fig. 5) no caso de furos ou rupturas, aplicáveis como vigas (4) e colunas (11) de sustentação, estruturas de aeronaves (12) e estruturas para coberturas de grandes vãos livres e portões, com todas as suas variáveis dependendo dos cálculos estruturais necessários para a configuração de carga e tração que as estruturas construtivas rígidas pressurizadas deverão suportar em cada aplicação.
