Abstract(s)
As construções mais antigas representam um significativo valor histórico e patrimonial do nosso país. No entanto, a implementação de ações de manutenção é um tema pouco desenvolvido, uma vez que o estudo do património histórico é complicado devido à especificidade, assim como à singularidade, do tipo de edifício alvo dessa eventual intervenção. Dependendo da idade da construção, assim como das suas características, a manutenção de um edifício de valor histórico pode tornar-se mais complicada, uma vez que o objetivo dessa intervenção é que o edificado não sofra alterações que desvirtuem a sua origem, obrigando assim ao uso de técnicas, materiais e equipamentos o mais ajustado possível a cada caso. Este trabalho pretende estabelecer um manual de inspeção e manutenção de um edifício histórico que celebra os 250 anos de existência, a Igreja Matriz de Rio Tinto. Para isso foi realizado um levantamento das principais anomalias detetáveis através de uma inspeção visual. Foi dada especial importância às paredes exteriores, uma vez que estas apresentam uma maior necessidade de intervenção, devido à presença de humidade ascensional e por infiltrações. A existência de humidade ascensional é um aspeto de abordagem exigente na elaboração de um plano de manutenção, uma vez que este tipo de patologia é de difícil tratamento, sendo que o grau de dificuldade aumenta com a idade da edificação. No edifício em análise, como se trata de um edifício com paredes de grande espessura, uma das soluções mais eficazes no combate à humidade ascensional seria o recurso a barreiras físicas, mas esta solução neste caso seria pouco viável, pois poria em causa a estabilidade e resistência da Igreja, e aportaria valores de intervenção que não seriam comportados pelo orçamento estabelecido. Assim, foram procuradas outras soluções menos invasivas e onerosas, que pudessem reduzir, ou eliminar, a humidade ascensional e evitar a presença de eflorescências e o consequente dano ao nível dos rebocos e pinturas. No final do trabalho é apresentado um Manual de Inspeção e Manutenção do Edificado (MIME), ajustado ao caso de estudo, que facilite a execução de inspeções futuras. Essas inspeções deverão possibilitar o processo de manutenção do elemento correta, preferindo executar manutenção preventiva a corretiva.
The oldest buildings represent a significant historical and patrimonial value of our country. However, its maintenance is an underdeveloped theme since the study of historical heritage is complicated due to the specificity, as well as the uniqueness, of the type of building to be treated. Depending on the age of the building as well as its characteristics, its maintenance can become more complicated since its purpose is that the building does not undergo changes, thus requiring the use of correct techniques, materials and equipment. Depending on the age of the building, as well as its characteristics, the maintenance of a building of historical value can become more complicated, since the objective of this intervention is that the building does not undergo changes that distort its origin, use of techniques, materials and equipment as closely as possible to each case. This work intends to establish a manual of inspection and maintenance of a historical building that celebrates the 250 years of existence, the Mother Church of Rio Tinto. For this, a survey of the main anomalies detectable through a visual inspection was carried out. Particular importance was given to the exterior walls, since they present a greater need of intervention, due to the presence of rising humidity and infiltrations. The existence of ascending humidity is a difficult aspect in the elaboration of the maintenance plan, since this type of pathology is difficult to treat, and the degree of difficulty increases with the age of the building. As it is a building with walls of great thickness, one of the most effective solutions in the fight against the rising humidity would be the use of physical barriers, but this solution in this case would be little viable, as it would put in question the stability and resistance of the church, and intervention values that would not be covered by the budget. This led to the analysis of other solutions which could reduce or eliminate ascent moisture and avoid the presence of efflorescence and consequent damage to the plaster and plaster. At the end of the work, a manual (MIME) is presented, adjusted to the case of study, that facilitates the execution of future inspections. These inspections should enable the process of maintenance of the correct element, preferring to perform preventive then a corrective maintenance.
