目前我国目前的冷弯薄壁型钢住宅墙体虽然满足规范要求,但在实际应用中许多性能指标与传统建筑墙体仍有较大差距,采用的轻质混凝土灌心技术,利用轻质混凝土对冷弯薄壁型钢的包裹提高了建筑整体隔音性能、防火性能、防腐性能。 At present, China’s current cold-formed thin-walled steel residential wall although meet the requirements of norms, but in practice many of the performance indicators and the traditional building wall is still a big gap, the use of lightweight concrete filling heart technology, the use of lightweight concrete Cold-formed thin-walled steel package to improve the overall building noise performance, fire performance, corrosion resistance.
