RESUMO: O estado de Minas Gerais possui o maior acervo artístico do barroco nacional, destacando os casarões e igrejas dos municípios históricos. Visto a importância histórica e cultural de tais edificações, torna-se necessária a restauração de seus elementos estéticos e funcionais, tais como as estruturas de madeira, em sua maioria. O objetivo deste trabalho é sequenciar as etapas de elaboração de projetos de restauração e recuperação de estruturas de madeira. E, como estudo de caso, apresentar a obra de restauração da Igreja Nossa Senhora do Carmo, em Diamantina, indicando o diagnóstico de suas patologias e a proposta para a intervenção. Foi necessário tratar quimicamente as superfícies contra infestações de insetos xilófagos e substituir parte da estrutura por madeira nova tratada, ancorada em nova fundação em concreto armado. Este reforço foi imprescindível para a estabilidade estrutural da Igreja, mesmo alterando parte do ambiente. Conclui-se que a escolha da técnica de recuperação de estruturas de madeira é condicionada por se tratar de uma restauração. É destacado também que as limitações de um projeto de restauração impedem, muitas vezes, o atendimento à normalização técnica quanto aos carregamentos e dimensionamento de estruturas. A técnica utilizada em Diamantina pode ser aprimorada para casos semelhantes e futuros estudos são importantes para a apresentação de metodologias menos destrutivas.ABSTRACT: The state of Minas Gerais has the largest artistic heritage of the national baroque, highlighting the mansions and churches of the historical municipalities. Because of the historical and cultural importance of such buildings, it is necessary to restore their aesthetic and functional elements, such as the wooden structures, in the majority. This work aims to sequence the stages of projects of restoration and recovery of wooden structures. As a case study, presents the restoration work of the Nossa Senhora do Carmo Church, in Diamantina, diagnosing its pathologies and proposing the intervention. It was necessary to chemically treatment against xylophagous insects infestations and replace part of the structure with new treated wood, anchored in a new foundation made of reinforced concrete. This reinforcement was indispensable for the structural stability of the Church, even changing part of the environment. It is concluded that the choice of the technique of recovery of wood structures is conditioned by the fact that it is a restoration. It is also emphasized that the limitations of a restoration project often prevent the obedience of technical normalization regarding the loading and dimensioning of structures. The technique used in Diamantina can be improved for similar cases and future studies are important for the presentation of less destructive methodologies.

Wood modification in general, is an environmental non-biocide method to modify and improve certain wood properties to enable its utilization for diverse purpose. In this study, Firmiana simplex wood was modify using low melting point tin-alloy as the heat-treatment medium. The anatomical properties of the tin-bath treated wood were studied using a light microscope and scanning electron microscope analysis. Microscopic analyses with a light microscope showed that the morphologies of the wood were less smashed by the impact of the treatment with no deformation of the vessels after tin-alloy treatment while scanning electron microscope revealed collapse in the wood structures with damages to the cell walls and vessels. It was also evident from scanning electron microscope analyses that tin-alloy penetrated the wood structure, therefore forming a film covering the cell walls and partly occupying the wood cell lumens.
