Prefabricated assembly type structure connection joint
The invention discloses a prefabricated assembly type structure connection joint, and belongs to the technical field of assembly type structures. The structure comprises concrete precast blocks, middle T-shaped solid web girders are arranged at the joints of the concrete precast blocks, concrete blocks and reserved annular steel bars are overlapped at the post-pouring positions of the joints, and on-site post-pouring additional annular steel bars are arranged at the post-pouring positions of the joints. Loads generated during on-site secondary concrete pouring can be effectively borne, more temporary supporting structures are prevented from being used, a joint part adopts a post-pouring wet connection mode, a joint is changed into a rigid structure from a variable-stiffness structure, post-pouring concrete adopts a high-performance micro-expansion type, the service life of the structure is effectively prolonged, and water leakage of the structure is avoided; the structure is reliable in connection node, good in integrity, rapid and convenient to prefabricate and install, and good in economical efficiency.
本发明公开了一种预制装配式结构连接接头，属于装配式结构技术领域。它包括混凝土预制块，在混凝土预制块接头处设置有中部“T型实腹梁”、接头后浇部位叠合混凝土块和预留环形钢筋以及现场后浇附加环形钢筋，结构装配完成后形成受力合理结构，在无跨中支撑的条件下，能有效承载现场二次浇筑混凝土时产生的荷载，避免使用更多临时支撑结构，接头部位采用后浇湿接方式，接头由变刚度结构转变为刚性结构，后浇混凝土采用高性能微膨胀型，有效提升结构的使用年限，避免结构漏水，此结构连接节点可靠、整体性良好、预制安装快速、便捷、经济性好。
