Anchoring system and anchoring method for thermoplastic resin matrix composite parallel rod cable
The invention discloses an anchoring system and an anchoring method for a thermoplastic resin-based composite material parallel rod cable, and belongs to the technical field of fiber reinforced resin composite material anchoring. The problem that an existing thermoplastic composite material cable for large-span space structures such as bridges and ocean engineering is difficult to anchor is solved, and the problems that a traditional clamping type anchorage device and a traditional bonding type anchorage device are subjected to local shear failure and pull-out failure, the cable anchor slippage amount is large, the anchoring efficiency is low, and the anchorage device size is large are solved. A pre-extrusion forming device is used for manufacturing each composite material rod in an anchoring area into corrugated rod bodies with different bending angles and tail end hooks, and a binding material with the mixing proportion of an efficient expanding agent gradually increased from the loading end to the free end of an anchorage device is injected into a steel anchor cylinder; the external load is transmitted to the steel anchor cylinder through the chemical bonding effect and the mechanical meshing effect between the cable body and the bonding material and the shearing and extruding effect of the hook at the tail end of the inhaul cable and the centering piece.
本发明公开了一种用于热塑性树脂基复合材料平行杆索的锚固系统及锚固方法，属于纤维增强树脂复合材料锚固技术领域。本发明解决现有桥梁、海洋工程等大跨度空间结构用热塑性复合材料索的锚固困难的问题，以及为了避免传统夹持式锚具与粘结式锚具存在的局部剪切破坏、拔出破坏、索锚滑移量大、锚固效率低及锚具尺寸大等问题。本发明利用预挤压成型装置将锚固区的每根复合材料杆制作成呈不同弯折角度、带末端弯钩的波纹状杆体，并向钢锚筒注入自锚具加载端至自由端高效膨胀剂掺入比例逐渐增大的粘结材料，通过索体与粘结材料间的化学粘结作用、机械咬合作用以及拉索末端弯钩与对中片的剪切挤压作用将外荷载传递到钢锚筒上。
