Packing type forward tension CFRP plate anchoring system and construction method thereof
The invention discloses a filling type forward tension CFRP plate anchoring system and a construction method thereof, and belongs to the technical field of external prestressing reinforcement in civil engineering. The filling type forward tension CFRP plate anchoring system comprises a to-be-reinforced structural member and a CFRP plate, and the two ends of the CFRP plate are connected with the to-be-reinforced structural member through anchoring devices correspondingly; at least one of the two anchoring devices is a filling type forward tension anchoring device, at least one supporting device is further arranged between the CFRP plate and the to-be-reinforced structural member, and the CFRP plate is far away from a neutral axis of the to-be-reinforced structural member so as to improve the prestress applying effect, so that the technical problem of midspan down-warping of the to-be-reinforced structural member is solved in a targeted mode, and the construction quality of the to-be-reinforced structural member is improved. In the filling type forward tension anchoring device, the loss of prestress can be avoided by inserting the plug pins into the strip-shaped holes and the pin holes and filling the plug pieces in the redundant space of the strip-shaped holes, and the construction is more convenient; and meanwhile, the tensioning frame, the sliding seat and the pre-tensioning frame can be easily disassembled after the plug pins and the filling plug pieces are inserted, so that the construction cost is reduced.
本发明公开了一种填塞式顺向张拉CFRP板锚固体系及其施工方法，属于土木工程中施加体外预应力加固技术领域，包括待加固结构件以及CFRP板，CFRP板两端分别通过锚固装置与待加固结构件相连，两个所述锚固装置中至少一个为填塞式顺向张拉锚固装置，在CFRP板与待加固结构件之间还设置有至少一个支撑装置，CFRP板远离待加固结构件的中性轴，以提升预应力施加的效果，从而针对性解决待加固结构件跨中下挠的技术问题，填塞式顺向张拉锚固装置中，采用在条形孔、销孔中插入插销以及在条形孔冗余空间填充塞片即可避免预应力损失，施工更加便捷；同时张拉架、滑动座、预张拉架在插入插销和填充塞片后可轻松拆卸，降低了施工成本。
