Tensile anchoring device
The invention relates to a tensile anchoring device. The tensile anchoring device comprises a tubular anchor rod body, a grouting pipe and an anchor head, wherein the grouting pipe and the anchor headare arranged in the anchor rod body in a penetrating mode; the anchor rod body comprises an anchoring section and a free section; the anchoring section comprises at least two anchoring subsections, and anchoring frameworks used for being transversely expanded to form the outer diameter smaller than the inner diameter of an anchor hole when being pressed are arranged between the adjacent anchoringsubsections. Strip-shaped holes used for allowing grout to flow into the anchor hole are formed between the adjacent frameworks of the anchoring frameworks; grout discharging holes opposite to the multiple strip-shaped holes are formed in the positions, corresponding to the anchoring frameworks, of the grouting pipe; and the anchor head is arranged at the end, away from the free section, of the grouting pipe. The structural tensile strength of the anchor rod can be improved easily, the permeability and the combination degree of concrete and a soil layer or a rock layer during grouting can beimproved easily, the combination degree of the concrete and a solidified concrete structure can be improved easily, and the overall stability and the tensile strength of the tensile anchoring device can be enhanced easily.
本发明涉及一种抗拉型锚固装置，包括管状锚杆本体、穿设于所述锚杆本体内的灌浆管和锚头；所述锚杆本体包括锚固段和自由段；所述锚固段包括至少两个锚固分段并相邻锚固分段间设置有用于受压时横向扩张形成外径小于锚孔内径的锚固骨架；所述锚固骨架的各相邻骨架间形成用于浆液流进锚孔的条形孔；所述灌浆管对应锚固骨架处开设有与多个条形孔相对的排浆孔；所述锚头设置于灌浆管的远离自由段端；利于增加锚杆自身的结构抗拉强度，利于提高灌浆时混凝土与土层或岩层的渗透度及结合度，利于提高与固化后的混凝土结构的结合度，利于增强其整体的稳定性及抗拉拔强度。
