Anchoring body for fiber reinforced thermoplastic resin matrix composite rod
The invention discloses an anchoring body used for a fiber reinforced thermoplastic resin matrix composite rod, and belongs to the technical field of civil engineering anchoring, the anchoring body comprises an FRTP rib, a centering ring, an anchoring steel pipe and a fixing cover, the anchoring section of the FRTP rib is located in the anchoring steel pipe, at high temperature, an FRTP prepreg tape is softened and is wound on the anchoring section of the FRTP rib in the clockwise direction, and the FRTP prepreg tape is fixed on the FRTP rib. A plurality of FRTP conical gradient structures are formed, a plurality of grooves with variable cross-section conical gradients are formed in an inner cavity of the anchoring steel pipe in the axial direction, the FRTP conical gradient structures are arranged in the grooves, and the anchoring section is fixedly sealed in the anchoring steel pipe through epoxy resin filler. The anchoring efficiency and the anchoring strength are improved, and the problem that the anchoring efficiency of the FRTP rib is reduced under the corrosive environment and the repeated fatigue load effect is effectively solved.
本发明公开一种用于纤维增强热塑性树脂基复合材料杆的锚固体，属于土木工程锚固技术领域，包括FRTP筋、对中环、锚固钢管和固定盖，FRTP筋的锚固段位于锚固钢管内，在高温下，将FRTP预浸带软化并按顺时针方向缠绕在所述的FRTP筋的锚固段上，形成多个FRTP锥形梯度结构，锚固钢管的内腔沿轴向开有多个变截面锥形梯度的凹槽，FRTP锥形梯度结构置于凹槽中，并通过环氧树脂填充剂将锚固段固封于锚固钢管内部。本发明提高了锚固效率、锚固的强度，有效解决解决了FRTP筋在侵蚀性的环境下及反复的疲劳荷载作用下锚固效率降低的问题。
