住建部近期发布了行业标准《装配式混凝土结构技术规程》,自2014年10月1日起实施。《规程》推荐了框架结构、剪力墙结构、框架-剪力墙结构等结构体系,并规定了各种结构体系适用的最大高度。框筒结构及新的结构体系如水平构件与竖向构件没有纳入该《规程》。《规程》要求,在节点及接缝处,主筋和横向补强筋要和现浇混凝土结构一样要保持连续性,节点区应采用现浇混凝土或者砂浆将预制构件连成整体。
The Ministry of Housing and Urban-Rural Development recently released the industry standard “Technical Specification for Assembled Concrete Structures” and implemented it on October 1, 2014. The Code recommends structural systems such as frame structures, shear wall structures, frame-shear wall structures, and specifies the maximum height to which various structural systems are applicable. Frame structures and new structural systems such as horizontal members and vertical members are not included in the Code. The Rules require that, at the joints and seams, the main reinforcement and transverse reinforcement should be of the same continuity as the cast-in-place concrete structure, and the prefabricated components should be integrated into the joint area by using cast-in-place concrete or mortar.
