Estudo das manifestações patológicas na Catedral Nossa Senhora das Mercês na cidade de Porto Nacional - TO

Abstract

The emergence of pathologies in old buildings is common, especially those with historical and cultural value, since it is very important to preserve the constructive characteristics, especially when it comes to works listed by IPHAN. The realization of inspections becomes indispensable in this type of construction, as is the case of the Nossa Senhora das Mercês Cathedral, object of study of the present work. When pathologies are found in their initial stage, it is easier to carry out a more efficient diagnosis and smaller repair works. One of the obstacles of the present work was in the collection of data, documents about the construction and repair works, because it is an old work dated from the beginning of the 20th century. In this sense, the objective of the work was to carry out a case study of the Cathedral, where it will undergo technical inspections in order to perform the best possible diagnosis for the pathologies found. The use of the Damage Identification Form to carry out the Damage Map was the main working instrument, as it is a historical and cultural heritage, the need for its use arose. As a result, it was observed that there is the presence of several pathological manifestations, mainly on the external and internal surfaces closer to the ground, indicative of an ascending humidity by capillarity, but that do not affect the general state of the structure, these can be solved with works of repair.
