Comparação ergonômica: aplicação de argamassa manual x argamassa projetada

Abstract

It is known that the most common construction method in Brazil is that of masonry constructions and, as a result, the application of plaster to finish the walls (IBGE, 2017). Because of this, this monograph aims to make a comparison between the two methods of application of plaster: by application of manual plaster and projected plaster. To be able to demonstrate the relationship between ergonomic quality and productivity, and bring awareness regarding the need for quality workspace and well-being of the professional. In order to make this comparison, the method used was the interview with professionals working in the field of construction, as well as making technical visits to case studies, who were applying the manual plaster, projected or both. In addition, the OWAS method was applied for postural assessment as well as the conference of regulatory standards 15 and 17 (2015). After performing these activities, the result was that even with issues to be solved, the application of projected plaster is the best ergonomic option, with 12% less harmful movements than the application of manual plaster and productive, with 49% less time, to cover the same area.
