Análise das conformidades de uma obra residencial unifamiliar no sistema Light Steel Frame: estruturas de elevação no método por painéis e fechamento vertical das paredes externas de vedação

Abstract

This work presents a case study with comparison criteria and qualitative analysis of the Light Steel Frame (LSF) constructive system in the panel method and vertical closing of the outer walls. The main objectives will be to investigate the execution of the LSF constructive system, between the interface of the structural elements and installation of the materials of the external walls of sealing, to indicate the conformities and to compare them with the Brazilian technical Norms, among them; ABNT NBR 6355:2012, ABNT NBR 15253:2014, up to the recently released Light Steel Frame standard, ABNT NBR 16970:2022, will also be used as a basis for technical manuals from the Brazilian Center for Steel Construction (CBCA). The object of study is a high standard single-family residence in the city of Caxias do Sul - RS. The methods applied in this course conclusion work can be replicated for different standards of single-family residence in LSF, low, medium and high standard. A case study was carried out from the beginning of the elevations mounted on the raft and specific points in the structure were verified, points that are important to maintain the structural rigidity, and in the external walls of sealing the application of the correct closing materials. The conformities found were satisfactory, with a result above 90%, demonstrating that the work had quality control and attention in the structural execution of the LSF constructive method and used adequate materials and with good technical performance.
