GB 50203—2011《砌体结构工程施工质量验收规范》对混凝土结构填充墙后植拉结钢筋如何进行现场非破坏实体检测作出了规定,为后植拉结筋施工和实体检测提供了依据。但GB 50203—2011实施中也发现了一些问题,如没有规定后植拉结钢筋的适用范围、给出的非破坏检验值检测时存在争议、没有规定钢筋锚固临界深度、对后植筋施工缺乏过程控制要求等,在分析上述问题的基础上提出了完善的具体建议。
GB 50203-2011 Code for Construction Quality Acceptance of Masonry Structure Engineering provides the rules for how to carry out on-site non-destructive entity testing of post-planting bracing steel bars with infill walls in concrete structures, which provides the basis for the construction and physical testing of post-bracing bars. However, some problems were found during the implementation of GB 50203-2011. For example, the application range of post-tensioned steel bars is not stipulated. There are controversies when testing non-destructive test values. There is no stipulation of the critical depth of steel bar anchorage and the lack of construction of rear planting bars Process control requirements, etc., based on the analysis of the above issues put forward a sound and specific recommendations.
