一种锚杆装置及利用锚杆装置锚固来加固截面的方法
摘要：
本发明公开了一种锚杆装置，包括：锚杆、套设在锚杆上的定位螺母和紧固螺母、以及用于容置锚杆的压板；锚杆内设有内螺纹孔，锚杆的插入端设置与螺纹孔连通的分隔槽，分隔槽用于将杆体分为若干受挤压向外扩的变形部；紧固螺母用于固定压板。该锚杆装置，可以有效控制锚杆的植入深度，一方面避免待加固件出现混凝土保护层剥离破坏现象，另一方面可避免加固层与待加固构件间出现界面剥离的破坏现象。本发明还公开利用该锚杆装置锚固来加固截面的方法。
摘要（英）：

The invention discloses an anchor rod device which comprises an anchor rod, a positioning nut, a clamp nut and a pressing plate, wherein the anchor rod is sleeved with the positioning nut and the clamp nut, and the pressing plate is used for accommodating the anchor rod. An inner threaded hole is formed in the anchor rod, a parting groove communicating with the threaded hole is formed in the inserting end of the anchor rod, and the parting groove is used for dividing a rod body into a plurality of deformation portions which expand outwards after being extruded. The clamp nut is used for fixing the pressing plate. According to the anchor rod device, the planting depth of the anchor rod can be effectively controlled, on the one hand, the phenomenon that a concrete protection layer of a member to be reinforced is stripped off and damaged is avoided, and on the other hand, the interfacial peeling damage phenomenon between a reinforced layer and the member to be reinforced can be avoided. The invention further discloses a method for reinforcing a section through anchoring of the anchor rod device.
