简介:摘要:现代装配式混凝土结构施工过程中存在大量预制构件与现浇结构的接缝处理,而且接缝位置往往处于结构受力复杂或设计要求较高的部位,如预制梁端、预制墙端、预制柱端等位置,因此,预制构件与现浇混凝土接缝位置的处理方式至关重要。目前,国内行业标准《装配式混凝土结构技术规程》JGJ1-2014(下文简称“规程JGJ1”)、国家标准《混凝土结构工程施工质量验收规范》GB50204和各地方标准规范中,均将预制构件的结合面质量作为一项重要内容,却并未对结合面的粗糙化处理提出具体的工艺要求及检验方法,各预制构件生产厂家并无统一标准进行预制构件粗糙面的处理工艺,因此有必要对预制混凝土构件粗糙面不同的处理工艺选择进行深入的研究。
