Combined connection concrete uplift pile
The invention discloses a combined connection concrete uplift pile. The combined connection concrete uplift pile comprises a reinforcement cage, wherein pier heads are arranged at the two ends of longitudinal reinforcements on the reinforcement cage, one ends of the pier heads are sleeved with concave sleeves, the other ends of the pier heads are sleeved with concave lengthened sleeves, stepped holes are formed in the concave sleeves, the pier heads are clamped by the stepped holes, the concave sleeves are provided with pagoda type screws, cross-shaped opening elastic sleeves are installed at the positions, with the smallest diameter, of the pagoda type screws, non-return limiting rings are mounted in the concave lengthened sleeves, and liquid curing agents are added into the concave lengthened sleeves. The combined connection concrete uplift pile has the beneficial effects that the working efficiency and safety are improved, it is effectively guaranteed that a connecting piece cannot be deformed through epoxy resin caulking sealing solidification, and the pulling resistance and shearing resistance strength of the connecting position are enhanced.
本发明公开了一种组合式连接混凝土抗拔桩，包括钢筋笼，钢筋笼上的纵向钢筋的两端分别设有墩头。所述墩头一端外套有凹型套，另外一端套有凹型加长套；所述凹型套内设有台阶孔，所述台阶孔卡住墩头；凹型套上安装有宝塔式螺杆，所述宝塔式螺杆上直径最小的地方安装有十字型开口弹力套；凹型加长套内安装有止回限位环所述凹型加长套内加入液体固化剂。本发明的有益效果是提高了工作效率及安全性，环氧树脂嵌缝密封凝固有效的保证连接件不会变形，增强了连接处的抗拔和抗剪切强度。
