Eccentric injection-increasing steel bar connecting structure between prefabricated reinforced concrete members
The invention relates to an eccentric injection-increasing steel bar connecting structure between prefabricated reinforced concrete members. The eccentric injection-increasing steel bar connecting structure comprises eccentric expanding screw heads, sectioning splicing strips, combined lantern rings and inner segment bearing bodies; the eccentric expanding screw heads comprise screw bodies and expanding screw bodies eccentrically connected to the ends of the screw bodies; a hollow cylindrical body is formed by splicing the plurality of sectioning splicing strips, and internal threads are arranged on the inner side surfaces of the upper end part and the lower end part of the hollow cylindrical body; the combined lantern rings are arranged on the hollow cylindrical body in a sleeving manner;a grouting slotted hole leading to an inner cavity of the hollow cylindrical body is formed in the hollow cylindrical body; the inner joint bearing bodies are mounted in the inner cavity of the hollow cylindrical body; the periphery of the hollow cylindrical body provided with the inner segment bearing bodies is correspondingly sleeved with the combined lantern rings; the combined lantern rings comprise force bearing rings, sectioning arc-shaped pads and sectioning arc-shaped wedges. When the eccentric injection-increasing steel bar connecting structure is used for connecting the prefabricated reinforced concrete members, the eccentric injection-increasing steel bar connecting structure has high connecting and bearing capacity and high position deviation adaptive capacity, and can adapt to large position deviation of two connecting ends.
本发明涉及一种预制钢筋砼构件间偏心增注钢筋联结结构，包括偏心扩径螺头、分瓣拼装条、组合套环和内节承体；所述偏心扩径螺头包括螺杆体和偏心连接在该螺杆体端部处的扩径螺杆体；多条分瓣拼装条拼合成空心筒状体，所述空心筒状体的上下两端部内侧面分别设置有内螺纹；所述空心筒状体上套置有组合套环；所述空心筒状体上设置有通往空心筒状体内腔的注浆槽孔；所述内节承体安装在空心筒状体内腔；安装有内节承体的空心筒状体外周对应套置有组合套环；所述组合套环包括承力环、分瓣弧形垫和分瓣弧形楔。本发明用于联结预制钢筋砼构件时，不仅具有较强的连接和承载能力，还具有较强的位置偏差适应能力，能够适应两连接端的较大位置偏差。
