Carbon fiber reinforced composite material rib base material anchorage device and anchoring method thereof
The invention relates to an anchorage device and an anchoring method thereof.The anchorage device comprises a clamping end steel bar, an anchor cup and a CFRP rib, the clamping end steel bar is connected with one end of the anchor cup, one end of the CFRP rib is anchored in the anchor cup, a bonding medium is poured into the anchor cup, the anchoring section of the CFRP rib is cut into a plurality of petals in the axial direction, and the CFRP rib is arranged in the CFRP rib. The tail ends of the split CFRP ribs are squeezed and gathered together through the squeezing anchor, and the split sections are expanded through the supporting frame to form expansion sections. The method comprises the steps that firstly, one end of the CFRP rib is subjected to sectioning, scattering and gathering treatment and inserted into an anchor cup, a bonding medium is poured into the anchor cup, after the bonding medium is solidified, the other end of the CFRP rib continues to be anchored, and anchoring of the CFRP rib is completed. According to the method, the tail end of the anchoring section of the CFRP rib is subjected to sectioning, scattering and gathering treatment, the cohesive force on the rib material is increased, the anchoring effect on the rib material can be improved, the CFRP rib can be prevented from slipping and losing efficacy, the high anchoring efficiency coefficient is obtained, and the method has high application value.
一种碳纤维增强复合材料筋母材锚具及其锚固方法，涉及一种锚具及其锚固方法，锚具包括夹持端钢棒、锚杯、CFRP筋，夹持端钢棒与锚杯的一端连接，CFRP筋的一端锚固于锚杯内，且锚杯内灌注有粘结介质，CFRP筋的锚固段沿轴向被切开分成多瓣，分瓣后的CFRP筋尾端通过挤压锚挤压归拢，并通过支撑架将该分瓣段撑开形成膨胀段。方法包括首先将CFRP筋的一端经过分瓣‑打散‑归拢处理，并将该端插入锚杯中，往锚杯内浇筑粘结介质，待粘结介质凝固后，继续锚固CFRP筋的另一端，即完成对CFRP筋的锚固。本发明通过对CFRP筋锚固段尾端进行分瓣‑打散‑归拢处理，既增大对筋材的粘结力，又能增大对筋材的锚固效果，可防止CFRP筋滑脱失效，获得高锚固效率系数，具有较高的应用价值。
