Estudio de los daños y refuerzos necesarios para la recuperación del techo de la iglesia de Salsipuedes-Córdoba-Argentina
Abstract
RESUMEN
La Iglesia de Salsipuedes en la Provincia de Córdoba fue construida en el año 1875 y su techo está conformado por una estructura de madera, vigas reticulada y correas sobre las cuales se apoyan bovedillas cerámicas, capa de mortero y tejas musleras.
La Iglesia está inhabilitada por precaución debido a la aparición de fisuras en barras del reticulado y desprendimiento de trozos de mamposterÃa en las cercanÃas del apoyo de las vigas principales. En este trabajo se estudia el estado tensional de las barras del reticulado y la materialización del apoyo de las vigas principales en los muros de mamposterÃa.
Constatado el alto valor de las tensiones de trabajo de las barras con manifestaciones patológicas, como asà también el inadecuado sistema de apoyo en la mamposterÃa, se proyectan los refuerzos necesarios para lograr un funcionamiento de la estructura con un grado de seguridad adecuado.
Palabras clave: estructuras; madera; patologÃa; patrimonio.
ABSTRACT
Salsipuedes The Church of the Province of Cordoba was built in 1875 and its roof is formed by a wooden structure, reticulate beams and straps which support ceramic arches tile mortar layer and tiling Legguards
The Church is disabled as a precaution due to the appearance of cracks in the grid bars and breaking away of pieces of masonry near the support of the main beams. In this work we study the stress state of the grid bars and support the realization of the main beams in the masonry walls.
Confirmed the high value of the working stresses of the bars with pathological manifestations, as well as inadequate support system in the masonry, projecting reinforcements necessary for safe operation of the structure with a degree of security.
Keywords: Wooden structures; pathology; patrimony.
