Multi-petal type self-locking inner anchor head and mounting method
The invention provides a multi-petal type self-locking inner anchor head. The multi-petal type self-locking inner anchor head comprises an anchor rod, a limiting nut, a series connection steel ring, a multi-petal type lock head, a banding steel ring, a conical base and other assemblies. The anchor rod is axially pressed, so that the lower portion of the multi-petal type lock head is opened and gradually moves downwards under the guiding effect of the surface of the cone frustum of the cone-shaped base, a conical face with the large lower portion and the small upper portion is formed, and the conical face is tightly attached to the bottom conical face after reaming. According to the inner anchor head, anchoring is carried out through mechanical occlusal force generated after reaming is carried out on the bottom of a straight hole, meanwhile, the anchoring force and friction force of grouting materials of the straight hole section are overlapped, and an anchoring mode which is safer, more reliable and better in durability is formed. The method is safe, reliable, good in durability, excellent in economical efficiency, high in construction efficiency and wider in application range.
本发明提出了一种多瓣式自锁内锚头，包括包括锚杆、限位螺母、串联钢圈、多瓣式锁头、箍紧钢圈、锥形底座等组件。通过对锚杆进行轴向施压，使得多瓣式锁头的下部在锥形底座的圆锥台表面的导向作用下张开并逐渐下移，形成下大上小的锥面，该锥面与扩孔后的底部锥面紧贴。该内锚头利用直孔底部扩孔后的机械咬合力进行锚固，同时该种锚固力与直孔段灌浆料的摩擦力相叠加，形成了一种更加安全可靠、耐久性更好的锚固方式。本发明不仅安全可靠、耐久性好、经济性优、而且施工效率高，适用范围更加广泛。
