Abstract
"ESTRUTURA PRé-MOLDADA DE CONCRETO ARMADO PARA COBERTURA DE GRANDES VãOS COM VIGA-TESOURA CONTìNUA". Patente de Modelo de utilidade para uma viga-tesoura pré-moldada continua 2 com emenda executada no local da obra 1, constituída por duas partes 8 produzidas em fábricas transportadas separadas até o local da obra e emendadas 1 formando a partir deste procedimento uma peça única 2. A emenda 1 poderá ser executada de três maneiras distintas de acordo com a matéria prima e mão-de-obra disponíveis na região: Primeira; emenda 1 por adição de graute entre as duas partes 8 da viga-tesoura 2, onde existem os insertos 10 necessários para efetivar a emenda(engaste) 1. Segunda; emenda 1 pela colocação de parafusos 15 em flanges 12 existentes no topo das duas partes 8 da viga-tesoura 2 transformando-as em peça única. Terceira; emenda 1 pela execução de solda entre as chapas 18 existentes no topo das duas partes 8 da viga-tesoura 2, tornando-as peça única, que após a secagem do acabamento 20 do local da solda 19 estará pronta para ser montada. Este sistema tem a vantagem que as peças 8 podem ser transportadas até o local da obra por equipamentos comuns (carretas) e após a emenda 1 são montadas com a utilização de apenas um quindaste para elevação."PRE-FRAMED CONCRETE ARMED STRUCTURE FOR COVERING LARGE SPANTS WITH CONTINUOUS SCREW". Utility Model Patent for a continuous precast scissor beam 2 with splicing performed on site 1, consisting of two parts 8 produced in factories transported separately to the site and spliced 1 forming from this procedure a single part 2. Amendment 1 may be implemented in three different ways according to the raw materials and labor available in the region: First; splice 1 by adding grout between the two parts 8 of the scissor beam 2, where there are the inserts 10 necessary to effect splice 1. Second; 1 by placing screws 15 on flanges 12 on top of the two parts 8 of scissor beam 2 into one piece. Third; splice 1 by welding between the plates 18 at the top of the two parts 8 of the scissor beam 2, making them one-piece, which after drying the finish 20 of the weld site 19 is ready to be assembled. This system has the advantage that parts 8 can be transported to the job site by standard equipment (wagons) and after splice 1 are assembled using only one lifting crane.
