Recyclable anchoring assembly of prefabricated concrete bottom anchor head
The recyclable anchoring assembly of the prefabricated concrete bottom anchor head comprises an anchor cable, a pull pin and the bottom anchor head, the bottom anchor head comprises an anchor head body formed by concrete pouring and an internal thread anchorage device embedded in the anchor head body and provided with internal threads, and the bottom end of the anchor cable is fixedly connected with a connecting section; the connecting section is matched with the internal thread anchorage device through threads, and the lead angle of the threads is larger than the self-locking angle. The pull pin is inserted into the connecting section and the internal thread anchorage device in the length direction to be locked in the circumferential direction, and the pull pin can be pulled out to be separated from and release the internal thread anchorage device; the anchor cable is firm and thorough in pouring combination with an anchoring body, the overhead condition is avoided, the bearing capacity after anchoring is guaranteed, meanwhile, the anchor cable is easy and convenient to recycle, the construction efficiency is improved, a foundation pit is firmly supported during anchoring, the requirement for the anchor cable to transmit torsional moment is not high, and the anchor cable is suitable for large-scale popularization and application. Finally, the purposes of reducing construction cost and improving construction efficiency are achieved.
本发明公开了一种预制砼底部锚头的可回收锚固组件，包括锚索、拔销和底部锚头，底部锚头包括混凝土浇筑成形的锚头本体和预埋在锚头本体内的设有内螺纹的内螺纹锚具，锚索底端固定连接设有连接段，且连接段与内螺纹锚具通过螺纹配合，螺纹的升角大于自锁角；拔销沿长度方向插入所述连接段以及内螺纹锚具在圆周方向锁定，且拔销可被拔出脱离并释放所述内螺纹锚具；本发明在与锚固体浇筑结合时较为牢固且浇筑透彻，避免出现架空状况，从而保证锚固后的承载能力，同时，锚索的回收操作简单方便，提高施工效率，且锚固时对基坑支护牢固，对锚索传递扭转力矩的要求不高，最终达到降低施工成本提高施工效率的目的。
