Abstract Industrialized lightweight buildings have great advantages associated with lower indirect costs, minimum construction wastes and faster construction processes. However, their main weaknesses lie in their acoustic performance and fire resistance. This paper develops and assesses a novel lightweight steel floor with high fire resistance and high acoustic performance for buildings. Acoustic measurements through laboratory tests were carried out according to ISO 10140:2010 and ISO 717:2013. Fire resistance was tested according to EN 1365–2:2000. The results demonstrate that using an appropriate structural and resilient layer through an optimized design, insulating the floor surface from the surrounding structure, separating structural systems between layers, minimizing flanking transmissions through resilient strips and joint sealing between boards, a Weighted sound reduction index of Rw (C; Ctr) ≥ 65 (−6; −14) dB, and a Weighted normalized impact sound pressure level of Ln,w (CI) ≤ 49,9 (4) dB can be achieved, along with a fire resistance of REI45.

先进的轻质钢地板走向高隔音和防火

摘要 工业化轻量化建筑具有间接成本低、建筑垃圾最少、施工速度快等巨大优势。然而，它们的主要弱点在于它们的声学性能和耐火性。本文开发并评估了一种用于建筑物的具有高耐火性和高声学性能的新型轻质钢地板。根据 ISO 10140:2010 和 ISO 717:2013 通过实验室测试进行声学测量。根据 EN 1365–2:2000 测试耐火性。结果表明，通过优化设计使用适当的结构和弹性层，将地板表面与周围结构隔离，在层之间分离结构系统，
