随着新材料、新技术的不断涌现,《屋面工程技术规范》GB50345—2004已不能再适合工程需要。鉴于此,为适应屋面工程技术的发展需要,《屋面工程技术规范》GB50345重新修订,并已在专业审查会上通过。介绍屋面防水等级、设防要求、防水层合理使用年限等方面的修订工作。结果表明,修订后的规范应用覆盖面广,具有实用性,可产生良好的经济效益和社会效益。
With the continuous emergence of new materials and new technologies, GB50345-2004 “Specifications for Roofing Engineering” can no longer meet the needs of the project. In view of this, in order to meet the needs of the development of roofing technology, “roofing technical specifications” GB50345 re-amended, and has been approved by the professional review. Describe the roof waterproofing level, fortification requirements, rational use of waterproof layer and other aspects of the revision. The results show that the revised norms apply a wide range of coverage, practical, can produce good economic and social benefits.
