O domínio tecnológico dos processos envolvidos nas operações primárias de transformação desta matéria prima, influenciam na qualidade e viabilidade destes produtos laminados. Neste trabalho foi estudada a laminação por torneamento da espécie Dendrocalamus giganteus. Inicialmente, este bambu foi laminado em um torno industrial sem centros e os resultados comparados àqueles apresentados na literatura para a obtenção de laminados de bambu por outros meios. Na seqüência, utilizando um torno mecânico, foi realizada a laminação em um torno com garras e fuso. Para então, avaliar a variação do torque durante o processo e a qualidade das lâminas, obtidas a partir de uma determinada geometria simplificada da ferramenta e rotação de acionamento. A experiência adquirida permitiu desenvolver e avaliar variações originais no processo de laminação por torneamento capaz de operar com e sem centros. A análise dos experimentos mostra a viabilidade do processo de laminação por torneamento, para a obtenção rápida, eficaz e fácil de lâminas contínuas com pequena espessura e grande largura, inviáveis de serem obtidas por outros meios. Colabora-se desta forma, para o desenvolvimento de processos industriais eficientes na transformação dos colmos de bambu, mais aptos a explorar o real potencial técnico e econômico desta importante matéria prima. / Among several industrial applications, bamboo veneering is very desirable, either by longitudinal lamination (splliter), by saw cut or lathe veneering. The technology used to primarily process this grass species (or raw material or Bamboo) has great influence in the quality and the viability of the product. In this work Dendrocalamus giganteus species was used to study lathe veneering. Initially it was laminated in an industrial Center less veneering lathe and the results were compared to what was presented in literature for obtaining bamboo veneer by other means. The second step was simulated a traditional veneering in a mechanical lathe, with a simplified tool configuration. The experience allowed a development and evaluation of a process that is simple, original and capable of centered or center less operation. Analyzing the experiments it was noted the viability of this process to obtain a fast and easy continuous lamination with dimensions (thin and very large) that would be unattainable by other processes. This is a great step for an efficient industrial development to exploit the real technical economical potential of this wonderful raw material.

As lâminas de bambu gigante, contínuas, largas e finas obtidas por processo de torneamento são um excelente material para revestir e reforçar madeira e painéis sarrafeados de eucalipto. Neste trabalho foram realizados ensaios de cisalhamento e tração normal na madeira de eucalipto de alta densidade com e sem o revestimento com lâminas de bambu. Foram produzidos painéis sarrafeados colados lateralmente (EGPs) de Eucalyptus saligna que foram ensaiados à flexão estática e a tração normal, segundo a norma NP EN 310, no sentido transversal do painel em que as ripas são coladas lateralmente. Verificou-se que as lâminas de bambu funcionaram como reforço mecânico para os casos de tração normal na madeira de eucalipto, mas que não houve reforço quando sujeita a esforços cisalhantes, independentemente da posição dos anéis de crescimento da madeira nas amostras. Neste caso as lâminas funcionaram apenas como revestimento. Verificou-se um comportamento frágil do painel sarrafeado de eucalipto durante sua ruptura a flexão no sentido transversal. Foram repetidos os ensaios para os painéis sarrafeados de eucalipto revestidos com lâminas de bambu gigante em dupla face. Verificou-se então um grande aumento na resistência mecânica à flexão estática no painel laminado. Com o reforço das lâminas houve uma mudança no comportamento do painel que deixou de romper de forma frágil passando a romper de modo dúctil, tornando o painel mais elástico e confiável ao uso. Além disso, foram estudadas as características de acabamento superficial das lâminas de bambu quando o material é submetido a processos de lixamento manual / Both bamboo and eucalyptus wood are important forest resources. The giant bamboo veneers continuous, wide and thin obtained by turning process are an excellent material for cover and reinforce the wood and laths edged glued panels (EGP) of Eucalyptus saligna. In this work was tested the eucalyptus wood of high density to shear and normal traction, then the eucaliptus wood was covered with layers of bamboo veneer and so repeated the same mechanic tests. Were produced panels EGP of eucalyptus that were tested for static bending, according to NP EN 310, in the direction that the laths are glued. It was found that bamboo veneers acted as mechanical reinforcement for the cases of normal traction in the eucalyptus wood, but there was no increase in eucalyptus wood subjected to shear efforts, regardless of the position of growth rings in wood samples. In this case the veneers functioned only as a coating. There was a fragile behavior of the panel EGP of eucalyptus during their break to shear efforts. The tests were repeated for the panels EGP coated with bamboo venners on double-sided. There was then a large increase in mechanical resistance to bending of laminated panel. With the increase obtained was a change in behavior of the panel that failed through the fragile break so ductile rupture, making the panel more elastic and reliable to use. Furthermore were studied the characteristics of roughness of the surface of bamboo veneer when the material is subjected to manual sanding processes

O bambu na arquitetura : desing de conexões estruturais /

Padovan, Roberval Bráz. January 2010 (has links)
Resumo: O bambu é considerado um dos mais antigos materiais para habitações, porém, o desenvolvimento de tecnologia própria, como material de construção de qualidade, vem acontecendo somente nas últimas três décadas, quando surgiu uma discussão mundial sobre sustentabilidade. A variável ambiental passou, então, a ser considerada em qualquer projeto de desenvolvimento, uma vez que influencia tanto na disponibilidade futura de matérias-primas e energia, quanto na qualidade de vida das populações. Uma das maiores dificuldades no pleno emprego do bambu na construção civil são as conexões estruturais entre seus elementos, que não permitem o uso da tecnologia de ligações aplicada a outros materiais, como o aço e a madeira maciça, para efetuar com eficiência a transferência de esforços, inviabilizando toda potencialidade estrutural oferecida pelo bambu. Este trabalho faz uma ampla revisão dos principais aspectos de arquitetura com bambu, bem como das técnicas de construção e conexões utilizadas. A partir de uma estratégia geral de inovação, baseada no processo de desenvolvimento de produtos, foi proposto o design de uma nova conexão estrutural, com execução de protótipo e projeto arquitetônico para ilustração de sua aplicação. Esta nova ligação visou contribuir com a viabilização da utilização do bambu na construção civil, pelo incremento tecnológico do material / Abstract: Bamboo is considered one of the oldest materials for housing, but the development of technoloy as quality construction material is happening only in the last three decades when a wordwide discussion about sustainability, where the environmental variable is to be considered in any development project, since it affects the future availability of raw materials and energy, as in the quality of life of people with improved environmental conditions. One of the biggest difficulties in full employment in the construction of bamboo are structural connections between its elements, which do not allow the use of executable technology of other materials such as steel and timber, for their efficiently transfer efforts, using all structural offered by bamboo creditworthiness. This work is a comprehensive review of the main aspects of the bamboo culture, as well as construction techniques and connections used. From an overall strategy of innovation, based on the product development process to design a new connection is proposed. This rebonding aims to serve as a contribution to the process of enabling the use of bamboo in construction, by technological increment of the material / Orientador: Marco Antonio dos Reis Pereira / Coorientador: Paula da Cruz Landim / Banca: Antonio Ludovico Beraldo / Mestre
