Friction structure of prestressed anti-floating anchor rod
The invention discloses a friction structure of a prestressed anti-floating anchor rod, the friction structure comprises a sleeve and a spiral stirrup, the top of the sleeve is provided with a first base plate, the bottom of the sleeve is provided with a second base plate, and the spiral stirrup is connected with the bottom surface of the second base plate; the sleeve is arranged above a target hole body, the second base plate is located at the top end of the target hole body and completes plugging of the target hole body, a grouting hole is formed in the second base plate, and the spiral stirrup below the second base plate extends into the target hole body and is pre-buried in a concrete structure body of the anti-floating anchor rod; the bottom end of the anti-floating anchor rod penetrates through the first base plate, the sleeve and the second base plate, extends into a target hole body and is pre-embedded in a concrete structure body of the target hole body; the top end of the anti-floating anchor rod is located on the top side of a to-be-fixed structure. The spiral stirrup is combined with the second base plate, so that the rigidity of a concrete structure body at the top of the anchor rod is enhanced, and the compression resistance, tensile resistance and shear resistance of the concrete structure body are improved.
本发明公开了一种预应力抗浮锚杆的摩阻结构，所述摩阻结构包括：套筒和螺旋箍筋，其中，所述套筒的顶部设有第一垫板，底部设有第二垫板，所述螺旋箍筋与所述第二垫板底面相接；所述套筒设置于目标孔体上方，所述第二垫板位于目标孔体顶端并完成目标孔体的封堵，且所述第二垫板上设有灌浆孔，第二垫板下方的螺旋箍筋伸入目标孔体并预埋于抗浮锚杆的混凝土结构体内；抗浮锚杆的底端贯穿于第一垫板、套筒、第二垫板并伸入目标孔体，预埋于目标孔体的混凝土结构体内设置；所述抗浮锚杆的顶端位于待固定结构的顶侧。通过螺旋状箍筋与第二垫板相结合，增强了锚杆顶部位置的混凝土结构体的刚性，从而提高混凝土结构体的抗压、抗拉、抗剪性能。
