Problems solved by technology
The disadvantage of the prestress adjustment method of the anchor cables in the prior art is that when it is found that the prestress loss of the anchor cables is too large and it needs to be re-tensioned, the corresponding adjustment method generally can only be performed by unloading and tensioning each anchor cable one by one. Fixing again is difficult, time-consuming and labor-intensive

The invention relates to a prestress adjusting method and an anchorage device. The prestress adjusting method comprises a step of fixing the anchorage device and a step of adjusting a prestress of ananchor cable, wherein the anchorage device comprises a base and an anchor plate laminated with the base; more than two first through holes are formed in the base along the lamination direction of thebase and the anchor plate; more than two second through holes and at least one third through hole are formed in the anchor plate along the lamination direction; the second through holes correspond tothe first through holes in a one-to-one manner; and the orthographic projection of the third through hole in the lamination direction is at least partially projected on the surface of the base, so that a pushing component can pass through the third through hole and push against the base. The prestress adjusting method and the anchorage device are capable of tensioning more than two prestress-lostanchor cables at one time, so that the operation is simple, time-saving and labor-saving.
Description
technical field [0001] The invention relates to the technical field of anchoring, in particular to a prestress adjustment method and an anchor. Background technique [0002] Anchorage is an anchoring device used in prestressed engineering and plays an important role in prestressed engineering. The quality of the anchorage directly affects the loss of the prestress of the anchor cable, and then affects the anchoring effect. The anchors in the prior art generally include an anchor plate with anchor holes. When the anchor is installed, the anchor cables are set in one-to-one correspondence with the anchor holes on the anchor plate, and the ends of the anchor cables pass through the anchor holes and are tensioned and fixed. On the anchor plate, and then fix the anchor plate on the reinforced object. [0003] During the use of the anchorage, the anchor cable connected to it will suffer from prestress loss. The disadvantage of the prestress adjustment method of the anchor cables...
