Prestressed prefabricated open-web sandwich plate structure system
The invention discloses a prestressed prefabricated open-web sandwich plate structure system, and relates to the technical field of open-web sandwich plates, which is used for solving the technical problem of high docking accuracy requirements on assembly joints in the construction process of existing prefabricated open-web sandwich plates and semi-prefabricated open-web sandwich plates. According to the prestressed prefabricated open-web sandwich plate structure system, lower ribbed beam wrapped U-shaped steel grooves are connected in a welding mode through connecting plates after prefabricated units are assembled; lower rib constructional steel bars are connected in a lap joint mode after every two adjacent prefabricated units are assembled; upper rib constructional steel bars are connected in a lap joint mode after every two adjacent prefabricated units are assembled; and after the lower ribbed beam wrapped U-shaped steel grooves are hoisted by the prefabricated units and are welded, lower rib prestressed steel bars penetrate through a reserved prestressed steel bar channel for post-tensioning, and grouting or direct anchoring is performed in the reserved prestressed steel bar channel after tensioning is completed.
本发明公开一种预应力装配式空腹夹层板结构体系，涉及空腹夹层板技术领域，用于解决现有的装配式和半装配式空腹夹层板在施工过程中拼装节点的对接精度要求过高的技术问题。本发明所述的预应力装配式空腹夹层板结构体系中，下肋梁外包U型钢槽在预制单元装配完成后通过连接板并采用焊接的方式进行连接；下肋构造钢筋在相邻两个预制单元装配完成后采用搭接的方式进行连接；上肋构造钢筋在相邻两个预制单元装配完成后采用搭接的方式进行连接；下肋预应力钢筋在预制单元吊装下肋梁外包U型钢槽焊接完成后，穿过预留预应力钢筋通道进行后张拉，并在张拉完成后向预留预应力钢筋通道中进行灌浆或直接锚固。
