1总则

1.0.1为规范装配式钢结构住宅现场检测，做到安全适用、数据准确、确保质量、便于操

作，制定本标准。

条文说明：国务院与住房城乡建设部发布了一系列政策和文件，明确提出了大力发展钢结

构建筑的新型生产建造方式的要求，装配式钢结构住宅建筑进入快速发展阶段。近年来，

虽然我省积极发展钢结构住宅建筑，但其一直存在有建筑质量和性能不高的问题。目前已

有了一些钢结构材料强度及构件质量的检测标准，但尚无一本既适用于工程现场检测且具

有可操作性的装配式钢结构住宅检测技术标准，为此制定本标准。

1.0.2本标准适用于装配式钢结构住宅中有关连接、变形、钢材厚度、涂装厚度等的现场

检测及检测结果的判定。

条文说明：装配式钢结构住宅的检测内容很多，具体检测内容可按照现行国家标准《建筑

结构检测技术标准》GB/T50344的相关要求执行，考虑到现行国家标准《建筑结构检测技

术标准》GB/T50344缺少相应检测方法和操作过程，本标准从装配式钢结构住宅的特点出

发，解决检测中常用的、重要的有关检测方法和操作过程。

1.0.3装配式钢结构住宅现场检测除应符合本标准外，尚应符合国家和山东省现行有关标

准的规定。

条文说明：装配式钢结构住宅现场检测技术涉及的应用技术面广、综合性强；在检测、鉴

定及验收中，凡本标准有规定者，应遵照执行；凡本标准无规定者，应按照现行有关标准

的规定执行。
